How to strengthen the garage door from thieves. Two ways to make swing gates. Expanding the garage door

The garage space is primarily necessary for the reliable storage of the car. In addition, many motorists equip a workshop, cellar, warehouse in it, keep numerous spare parts, tools, seasonal tires in the garage. It is important to know how to protect the garage from opening. Today we will look at the most significant factors, effective methods. Let's find out how the protection of the premises differs depending on the type of materials from which the garage is built. Having learned numerous helpful tips, everyone will be able to ensure safety in their garage space.

It turns out that the protection of the garage largely depends on what material it is made of. Let's consider all the main types of garages, find out how safe it is to store a car in them, how to strengthen protection.

Monolithic reinforced concrete building. it the best option for the garage, so that it is really strong, reliable, and ensures safety. Such a design can be ordered at the Russian plant of reinforced concrete products. Of course, you will need craftsmen, appropriate specialized equipment for its transportation and installation. But at this garage it is quite difficult to break through the wall. At good hinges and castles, gates, the building will become impregnable.
brick garages. These structures can also be very durable. But it all depends on the material, the quality of the masonry. In addition, there is a weak point: floor slabs on the gate. Criminals raise them with jacks, providing a clearance for themselves. Experienced garage workers simply attach such a plate directly to the frame garage door, ensuring the integrity and reliability of the design.

metal buildings. Unfortunately, widespread professional sheet garages are becoming the least protected. Even teenagers cope with them without much difficulty. The metal panels themselves are vulnerable. In addition, there is a danger that the entire structure will simply be lifted off the ground. The problem is also in the thickness of the metal: if it is thin, the garage is opened simple fixture reminiscent of the usual can opener. Therefore, it is important to use thick, durable metal. Good decision- sectional garage, which is assembled on site. Of course, the floor must be connected to the walls. It is also worth taking care of pouring the foundation so that it is impossible to dig.

When there is an opportunity to choose, it is better to stop at a ready-made monolithic reinforced concrete garage. If it is not there, you will need to engage in strengthening the existing structure.

Important Points

The following factors are also significant. If you have to choose a new garage, pay attention to the following points.

It is desirable to have neighbors with safe, well-equipped and protected garages. This is especially true in cooperatives. If the premises adjacent to you are very poorly protected, it is through them that intruders can get into your garage. This risk factor is very serious.
The specificity of the area, as well as the level of crime in it, plays an important role. When a place is poorly lit, little visited, it is hardly visible from different sides, the likelihood of the appearance of criminals increases dramatically. It is better to purchase a more expensive garage, but in a safe place, in a quiet area.
Finally, the presence of an expensive car next to you can become a negative factor. It happens that an elite car is stored in the garage, but it is well protected, closed, and has an alarm. And then the criminals can try to get into it through the next room. That is, the neighboring garage is at risk.

Be careful. To make the garage more reliable, try to eliminate all risk factors, as well as take additional security measures.

We strengthen the garage

Now we will learn how to protect garages from opening, consider various options. We have already found out that metal structure must be welded from thick material. It is necessary to strengthen well not only your garage, but also neighboring ones. It is required to prevent undermining, lifting the box. Now let's move on to the gate.

Gate protection

The weak link is the garage door. Unfortunately, quite often criminals resort to forced opening of the gate: they make jerks with the help of cars, attaching a cable to the leaves or the handle of the gate. This method is quite effective, especially if the place is poorly visible and illuminated, the area is deserted. To increase the level of security, it is necessary to make the sashes solid, without slots and gaps.

Make additional stiffeners on metal gate Oh. This is a good way to strengthen them. The best option- made of iron with a thickness of at least 3 mm. The frame must also be strong. It is desirable to weld it from channel number 6, like a box. Additional measure- fasten the box with a reliable weld to the walls, beams of the garage.

Remember that attackers often wring out the gate using a crowbar. Here you need to eliminate the gap between the two leaves of the swing gates. Weld a strip of metal so that the crowbar cannot be pushed into the slot.

loops

Vulnerability is often associated with loops. They are additionally strengthened by welding bolts. But this does not always help either, since the heads of the bolts are cut off by a grinder, knocked down with a chisel.

Optimal modern solution- install internal hinges. In their design, structure, they resemble car hinges. Of course, they will be more difficult to install, but it is also extremely difficult for criminals to get to such loops.

Locks

Locks must be extremely secure. It is advisable to use combinations of several locks different types. The external lock protects the metal casing quite well. True, experienced criminals also get rid of casings by threading a crowbar through the shackle. The lock design with hidden rods is more reliable. They have a streamlined shape, which does not allow you to easily put on the chain.

Most effective solution- install, which will be securely closed from the outside. Also, experts advise installing several locks, keeping a distance of 30 cm between them. Then, even if you try to break in, the load will be distributed. Be sure to make sure that the locks are well deepened, in no case protrude beyond the gate.

Electronic security

It is most prudent to install an alarm system with console protection in the garage. Then, when a penetration or attempted burglary is detected, an outfit will immediately leave for the place. You won't have to pull telephone wires because the radio channel is now used. If you just want to scare off intruders, set up an audible alarm: a siren will turn on when someone enters. Carefully disguise the alarm switch.

Video: we provide reliable protection for the garage

Worth seeing and useful materials on video. Here, motorists tell how to protect garages from opening, show everything on concrete examples. For example, you can make reliable garage doors by equipping them with a special lock hatch. So the level of security will increase significantly.

You also need to pay attention to correct installation modern reliable locks on the gate in the garage. The following video details how to do this.

If you follow the advice, act comprehensively, do not leave weaknesses in the protection of the structure, you will be able to ensure safety in the garage.

You will need

- pipe Ø100 mm;
- corner 100x100 mm;
- angle grinder ("Bulgarian");
- welding machine;
- cement;
- sand;
- edged board and timber for formwork;
- carpentry tool;
- shovel and bayonet shovels.

Instruction

Cut out the blanks for the gate. For racks, use a pipe Ø100 mm or a corner 100x100 mm. Their length is determined by the sum of the height of the gate and the length of the ends embedded in the ground (0.8-1 m). With a planned gate height of 2 m, the length of the blanks should be 2.8-3 m.
Make a jumper connecting the racks from a 100x100 mm corner. Its length should be equal to the width of the gate. For standard gates, it is assumed to be 3 m. If a pipe is used as posts, cut off one corner flange on both sides at an angle of 30 ° and give its edge a concave shape. This is done so that the edges of the corner fit well against the uprights when they are welded.

Assemble the gate frame from the blanks on the ground, choosing a more even place for this. It should look like the letter "H" - two racks and a jumper laid between them at a distance of 2 m from their top (or 0.8-1 m from the bottom). In this case, two conditions must be ensured: the parallelism of the racks between themselves and the perpendicularity of the jumper with respect to the racks.

Weld the jumper to the uprights. Both shelves of the corners must be securely welded with a continuous seam. Weld any pieces of metal to the jumper in two or three places, pointing them down. They will play the role of reinforcement, firmly connecting the jumper to the foundation.

Dig a trench for pouring the foundation. Its width should be 350-400 mm, length - 3.5 meters (for a 3-meter gate). Required depth trench is determined taking into account the depth of soil freezing, its type, level ground water. For simplicity, you can take it equal to the depth of soil freezing in your area, which can be found on construction sites.

Make wooden shields from edged board and assemble formwork from them. Its dimensions in plan should be 0.3x3.3 m. It is advisable to make the walls of the formwork slightly expanding towards the bottom - in order to avoid the expulsion effect of the soil on the foundation.

Place the gate into the formwork so that the lintel is flush with the ground and the posts are vertical. To do this, place supports made of stones or metal under the racks or lintel and secure the racks on both sides with stops. Lay reinforcement from any type of metal in the formwork - wire, scraps metal profile etc.

cook sand-cement mortar with a ratio of 1:4 (cement:sand) and pour it into the formwork. To use less mortar, fill the formwork with stones and broken bricks. During pouring, tamp the solution with a shovel. The surface of the poured foundation should be flush with the ground and the lintel. Before hanging the gate itself, give the solution time to harden - at least a week.

From the article you will learn how to strengthen swing and sectional garage doors to increase the strength of structures and the level of protection against burglary. We will review the most popular and effective ways. Tips and tricks will help you secure your car and other valuable property.

How to strengthen garage doors: increasing the protection of structures with hinged doors

Before you strengthen the garage door, equipped with hinged doors, identify all the weak points that attackers can take advantage of.

List of the most common problems:

loose junction of the valves to each other;
protruding loops for padlocks;
the presence of handles and other elements to which a cable can be attached;
loops placed outside for hanging sashes;
weak locks;
sashes without stiffeners, made of thin sheets of steel;
lack of alarm.

Ideally, garage doors should be devoid of all of the above disadvantages. Next, we will talk about ways to strengthen hinges and sashes, as well as the nuances of choosing and installing locks.

How to strengthen swing gate hinges

There is only one way to strengthen the loops located outside. Weld special metal bars on them. This will make it much more difficult to cut.

Important! This method is used only in cases where it is impossible to install the gate so that the hinges are inside the garage. If the attacker is armed with an acetylene cutter, the amplification will not save.

To exclude the possibility of removing the gate from the hinges, weld metal pins or plates to the leaves as shown in the photo below.

Photo No. 1: strengthening the swing gate to protect it from being removed from the hinges

When the doors are closed, the metal plates slide out to the sides and enter the holes in the walls. In this case, the gate will not open and fall out even after cutting the hinges.

How to strengthen swing gate leaves

Let's start with the fact that for maximum reliability swing gates must be made of steel sheets with a minimum thickness of 3 mm, and the frame and box - from channels No. 6.

To strengthen the sashes, additional stiffeners are welded to them. For their manufacture, they usually take:

How to further strengthen the protection of swing gates from burglary

Loops for padlocks, handles and other elements to which a cable can be tied are best removed altogether or installed on internal surfaces.
Make sure that the sashes are as close to each other as possible. If necessary, weld a metal plate onto one of them. Fitting density is also achieved by mounting eccentric locks and vertical bolts.
For additional protection premises, lattice doors can be installed behind the main gate, which will be locked to the inside the padlock. From the outside, weld a steel plate to hide the locking device from prying eyes. You will have to touch the lock to open it.

Selection and installation features of locks for swing gates

When choosing locks, immediately ask the seller to show models designed specifically for garages. Such locking devices are marked with the letter "G". Lever and disc locks are optimal. Burglary resistance must be at least 3rd class.

Basic rules for installing locks.

Mechanisms and fasteners must not protrude beyond the plane of the gate from the outside.
For fixing, use reliable bolts (thickness - 8 mm and above).

Important! Place 2-3 locking devices of different types at a distance of 30-40 cm from each other. Experts recommend additionally protecting the locks with metal windows.

How to strengthen sectional doors

Sectional doors can be reinforced with steel profiles. The need to strengthen structures arises in three cases.

The gates are installed in a room where significant temperature fluctuations are possible or air humidity exceeds the permissible values.
Sandwich panels are subject to constant high wind loads.
The entrance to the garage is located on sunny side(thermal deformations are possible).

If the steel profiles were not included in the package, you will have to buy them separately. Prices are more than acceptable.

Important! If you order sectional doors with the possibility remote control, do not save on electronics and ask if the equipment is equipped with remote monitoring systems, protection against interception of signals and their encryption.

To monitor the state of structures, connect the automation to the Internet and install the application on your smartphone. So you can monitor the garage in real time.

The protection of sectional doors against burglary is also enhanced by installing secret locking mechanisms. This method of improving security is best suited for manual models, since hidden locks are not associated with automation.

Garage door alarm

Installing a security system is a great way to protect both manual and automatic sectional garage doors from burglary. In Moscow, alarms connected to centralized monitoring panels of private security agencies are popular. When an alarm is received, rapid response teams are sent to the facilities.

You can also equip the gate with a howler alarm that makes loud noises when unauthorized entry is attempted. Don't forget to install and mask the switch.

For any motorist, a garage is not just an additional room near the house, but a building element that serves to store an iron horse, and is also used as a pantry or workshop. Therefore, here, too, climatic conditions must be provided that will be comfortable for the car. And this may require repair of the garage door or insulation, since this part is vulnerable. There are simple troubleshooting steps. Knowing them, you will be able to carry out all the work with your own hands.

Garage door insulation

For proper insulation the gate must follow certain rules:

pay attention not only to the insulation of the door leaf, but also to the sealing of joints and cracks using a material that is characterized by a high coefficient of expansion;
carefully select a heater, the thermal conductivity of which is higher than that of the walls of the garage;
compliance with safety regulations;
thickness thermal insulation material must be the same over the entire area of the goal;
carry out the process at a positive temperature.

Do I need to insulate and why?

They are usually made from metal. Because of this, problems arise. AT winter time year they are prone to freezing. This happens due to the fact that uneven freezing of the garage perimeter occurs, since only the gates are metal. After all, it is metal, and not brick, the most heat-conducting element. Because of this, the gate condenses moisture from inside the garage, and at negative air temperatures, this condensate turns into ice.

Condensation occurs at any time of the year due to daily temperature fluctuations. And this leads to some problems:

Corrosion due to prolonged exposure to moisture. Non-insulated gates rust much faster, and this happens even when stainless steel was used for their manufacture.
Condensation settling on all metal objects in the garage, including a car that usually drives into a cold garage warm due to constant work. The garage is designed to preserve it, but in the absence of insulated gates, on the contrary, it contributes to its damage. In an unprepared garage, the car rots faster, and this, unfortunately, is not a myth.
The ice does not allow the gate to be opened. Attempting to do this quickly may result in damage.

There are many reasons to insulate your garage door as soon as possible. But you need to do it right.

Material selection

The first question to be solved is the choice of thermal insulation material. Each of them has its own specifications which can be both an advantage and a disadvantage. The table will help you to get acquainted with them.

Table: insulation materials

Knowing these characteristics, you can get a holistic view of each material, on the basis of which you can make a choice:

Expanded polystyrene is not as resistant to fire, however, the advantages are low thermal conductivity and high stability to moisture.
Polyurethane foam allows you to perform insulation without seams, and it can be applied to an unprepared surface. This material is absolutely resistant to temperature extremes, chemicals, thereby ensuring the strength and durability of the insulated gates. But for this pleasure you will have to pay a considerable amount.
Mineral wool does not burn. Since the risk of sparks is high in the garage, it is worth considering using this material. However, when installing it, you need to take care of additional hydro and vapor barrier.
Styrofoam almost does not conduct heat, has high moisture resistance, which is very important when insulating gates. And also, due to its low density, there will be no additional load on the gate. Styrofoam is absolutely safe for humans and environment. Moreover, it is sufficient available material and easy to process. Therefore, it is polystyrene that is considered almost ideal for insulating metal garage doors.

There are other materials that are suitable for this purpose, for example liquid foam- penoizol.

Calculation of the amount of material

For quality insulation gate in advance you need to carefully calculate the consumption of all necessary materials. In addition to the selected insulation, you will also need a facing material, which at the end of the work will finish the gate. It could be:

lining;
corrugated board;
Fiberboard or MDF;
plywood (it is recommended to choose moisture resistant);
OSB boards ( perfect option, because it is highly durable, vapor-tight, easy to process, cheap).

To calculate the amount facing material you need to know the dimensions of the gate. As a rule, when using OSB boards for insulation, two pieces are enough, since standard sizes them are 125*250cm.

For cladding, you will need to mount the crate. You need to place it on the door leaf. For this it is better to take wooden bars at least 4 * 2.5 cm. You need to mount them around the perimeter of the canvas, while you can mount them on metal corners. When calculating its general design, the dimensions of the load-bearing elements of the gate, foam boards (or other insulation) should be taken into account, while the fastening step of the facing material should be at least 40 cm. The bars must first be treated with an antiseptic to prevent them from rotting.

For mounting the crate, you will also need galvanized self-tapping screws:

for fastening to the side surface - 3.5 * 30 mm;
for end mounting - 4.5*70 mm.

The length of the self-tapping screw depends on whether the crate will be attached to metal corners or a pipe. In the second case, the length must be increased. To calculate their number, it is necessary to make a drawing of the gate insulation on paper.

It is better to fix OSB boards with screws with a press washer 32 mm long. Quantity is calculated in the same way.

For high-quality insulation of metal gates, you must not forget about corrosion protection. Suitable for this special primer. It must be applied to a degreased surface.

Can't do without polyurethane foam, which is needed for attaching insulation plates to the gate and sealing gaps.

Tools

For high-quality insulation of metal gates in the garage, you need a number of tools that almost every good owner has:

Electric drill.
Drill. It is necessary to take care in advance of the availability of drills for working with wood and metal (if the crate is wooden).
Screwdrivers of various sections. Can be replaced with a screwdriver.
Wood saw. If there is, then a jigsaw. It will speed up the work.
Metal brush with metal bristles or a suitable drill bit.

In addition to these tools, you may need others, for example:

brush or roller for applying antiseptic;
a hammer;
core (used to mark the holes of the drill);
tape measure or meter ruler;
square;
construction knife;
sandpaper;
clamps (needed to fix the elements).

Step-by-step instruction

After the material is selected and calculated, the tool is prepared, you can proceed to the direct insulation of the garage door. All work takes place in several stages (in the case of foam insulation):

Preparatory work. This stage in no case should you miss it, since it largely depends on the quality of thermal insulation. If there is rust on the canvas, you need to get rid of it using a special nozzle on the drill. It is recommended to go over the entire surface of the gate with sandpaper, and then with a degreaser. Next, an anti-corrosion primer is applied in two layers (the second layer can be applied only after the first one has dried well). Now is the time to install the waterproofing layer. Suitable for this bituminous mastic, vapor barrier membrane, isolon.
Lathing installation. On the inner surface gate to mount the crate. It can be metal or wood. You need to fasten to the base of the metal sheet with self-tapping screws or screws. Make fasteners according to the drawing, and for this you need to make markings, and then drill holes without overheating the drill. The bars must all be solid, it is recommended to attract with clamps, and then drill with a thin drill.

If there is a problem with fastening the lower horizontal beam to the frame or gate, then it can only be fastened to the end. If it is possible to remove the gate, then this must be done in order to get the tool to the frame.

If desired, the plates can be painted in your favorite color, however, even without this, the main goal of insulation will be achieved.

Do-it-yourself garage repair: how and why to do it

Timely implementation repair work- a necessity, since cold air can enter through the gate, which adversely affects the technical condition of the car. Fortunately, carry out Maintenance you can do it yourself.

How to raise the gate

There are several reasons why this type of repair is required. Most often, it is necessary to raise the gate when it is impossible to open it not only in winter due to icing, but also in summer. by the most in a simple way to solve this problem is to cut the gate with subsequent concreting of the passage. However, it is better to carry out a full repair so as not to reduce the dimensions of the structure.

Gate lifting steps:

Dismantle them, release the frame. Before removing the gate from the hinges, it is recommended to wash the mortar between the bricks.
Remove several rows of bricks from the top of the garage opening. Instead of bricks, lay a channel or a high-strength corner, which are fixed with anchor bolts. This will save the gate structure from further destruction.
On the lower section, slightly raise the backfill. You can close the gap between the gate and the floor in another way, for example, by concreting. You can also make a small sill. Regardless of the way to eliminate the gap, you need to ensure that the slope is directed towards the street, otherwise excessive moisture in the garage cannot be avoided, especially during heavy rain.

How to fix the frame on the wall

One of the problems that can affect the ease of use of the garage is the separation of the gate frame from the wall. Spend this species repairs can be done on your own. This is done as follows:

Remove the old gate.
to the gate with inside weld a metal belt.
Replace old hinges with new ones.
In places where the frame is attached to the wall, it is recommended to install metal corners and fittings.
Mount the gate, observing all the rules.

It is necessary to carefully strengthen the gate frame to the wall, since this is one of the vulnerabilities garage.

How to replace a gate

In some cases, a complete replacement of the gate is necessary. This can happen for many reasons, such as when the structure has become unusable due to rust and rot. The door replacement process only takes a few hours. During this time, the following work is performed (after dismantling the old gate):

Frame installation. It will give the gate the necessary rigidity and allow the doors to move easily. First, the installation of the external and internal parts frames to the opening. For this, metal pins with a length of 150 to 180 mm are used (it is recommended to process their ends welding machine sanded and painted).
Spend additional mount gate with iron lintels. The distance between them should be from 2 to 4 cm.
Fixation of shutters on hinges.

How to fix skew and adjust correctly

Problems arise when the geometry of the gate is violated. You can solve it depending on the cause of the malfunction:

How to increase the size of the gate without dismantling the roof

The complexity of the procedure for increasing the opening directly depends on the structure of the roof and the ceiling of the garage. Before you try to increase the garage opening, you should understand the design of the roof and find out how wide the garage door should be. Most often, three main schemes for arranging the supporting frame of the roof are used:

On brick or cinder block walls, transverse floor beams, steel or wooden, are laid. The beams are laid with a crate, insulation and waterproofing. In this case, it is possible to increase the doorway without major alterations to the front wall of the garage;
The case when, instead of beams in the transverse direction, hollow lightweight iron is laid on the side walls concrete plates overlap. In this case, the weight load load-bearing structure the roof is placed on the side walls, so a relatively small part of the load falls on the brickwork;
The most difficult option is the case when concrete slabs are located in the longitudinal direction. In this case, the floor slabs largely rest on the front wall of the garage, which does not allow simultaneous removal or destruction of several rows of bricks between the door frame and the floor slab.

Note! The presence of a concrete jumper over the garage door can simplify the situation. Competent builders in this way, when building a garage, transferred part of the load from the floor slabs to the side segments of the wall.

If there is no serious load on the front wall and garage doors, you can expand the size for replacing the frame with a very simple operation. To do this, with a cutting wheel on a stone, it is necessary to make an incision along the measured vertical border of the new opening and chop off part of the brick wall with perforators. Today, instead of the old garage doors of 250 cm, they are increasingly using input structure 270 cm wide.

Expanding the garage door

It is much more difficult to increase the opening if the upper rows of bricks above the frame and the loot itself bear a certain load from the weight of the floor slabs. In this case, changing the height or increasing the width of the opening is possible only by installing additional unloading beams:

Option one - to increase the size of the entrance to the garage room using a steel I-beam shroud as a temporary fastening;
Option two - cut a niche in the brickwork above the frame for the installation of a reinforced concrete lintel and use it as a transverse beam holding the bulk of the slabs;
Use steel angles to assemble a horizontal bar to support the weight of the boards and brickwork at the time of "redrawing" the opening of the garage door.

Note! All three methods are of the same type and suggest the possibility of increasing the size of the entrance only after the gate frame is unloaded.

How to expand and enlarge the opening with a steel corner

The above method to increase the size of the garage opening can be called low-impact and the cheapest, due to the fact that a relatively small amount of auxiliary materials are used in the restructuring than in the method with reinforced concrete or I-beams horizontal beams.

To increase the size of the opening, first of all, you will need to install an additional horizontal composite beam of two corners with a shelf width of 75 mm. At the initial stage, you will need to mark up the front wall above the entrance. We mark the horizontal and vertical line dimensions of the new gate.

Using a perforator, we cut a groove in the wall with a width of 8 mm and a depth to the width of the corner shelf. First, a groove is cut from the inside of the wall. Three segments of a corner are cut along the dimension line, which are recessed into a cut groove and welded with the letter P.

In a similar way, a groove is cut, then the corners are installed from the outside of the front wall. It turns out a design of two corners, welded and fixed on the wall in the form of two letters P, edging the contour of the future gate. To prevent the assembled frame from falling apart, it will be necessary to increase the strength and rigidity by welding on the transverse jumpers.

Dismantling masonry as a way to increase the opening of the garage door

Before welding the lintels, it is necessary to remove some of the bricks above the horizontal beam of the old gate. To do this, install a support from a thick log or timber in the central part. Only after that, it is possible to cut out part of the masonry bricks with a perforator, and a gap is formed that is sufficient to connect the corners of the new frame with jumpers.

Next, you can increase the size of the garage door opening. To do this, you will need to cut the remaining brick from the masonry, through the knocked out holes above old beam stretch two channels, under which to install additional props from wooden beam. horizontal beam old garage doors can be cut and thrown away.

We got a new frame for the garage door. It remains only to strengthen the paired corners with overhead elements, if necessary, replace the channel on the threshold. Since for the most part new gates are sold complete with a frame and dummy elements, it is easiest to insert finished structure into the prepared frame from the corner, align it vertically and horizontally, and then weld it to the base by electric welding.

Conclusion

A similar way to increase the size of the opening can be used if there are no more than 4-5 rows of bricks above the old gate, that is, the ceiling height is no more than 240 cm. For higher gables, the strength of two corners will not be enough, and more in a safe way to increase the opening will be the use of an external I-beam as an intermediate support for the ceiling slabs.
