How to increase the height of the garage door: a step-by-step master class. We raise garage doors: complex problems and simple solutions Increasing the opening of the garage door in height

Often the height of the gate is already finished garage does not suit the owner. Perhaps the person decided to buy a new car, say, an SUV, whose height is higher than usual cars, or it became necessary to use the garage for other purposes when you need to drive a small truck e.g. Gazelle.

But the gates for a private garage were previously created using a certain amount metal in order to save money - the calculation of the amount of materials used was carried out taking into account the size of the standard steel sheet 2-3 mm thick (photo 1).

Today, the height of the garage doors of other owners has ceased to suit, and many have begun to increase this size (photo 2).

Buying materials and choosing a tool

Of course, you can invite specialists who will do it quickly and efficiently. However, not everyone has enough money to pay for the work of hired workers and purchase the materials they use. Often, craftsmen require the purchase of new metal, which is an order of magnitude more expensive than the one that was already in use.

In turn, the garage owner can pick up the necessary rolled metal from an organization that collects scrap metal. The material selected from scrap can cost 2-3 times less than you have to pay for new rolled metal. At the same time, the strength of metal structures made of old metal is quite enough to ensure the strength of the finished product.

But it is not recommended to save on tools and equipment. Need to prepare workplace by setting the required height strong scaffolding- when performing work, a person must be in a stable position, which will prevent him from falling with a working tool and getting injured.

The hammer drill and angle grinder must be powerful, and equipment such as drills and cut-off wheels must be purchased. good quality on which the speed of work and the safety of the worker will depend.

For example, for cutting brick wall It is recommended to use special cutting diamond wheels. For welding, it is enough to use a small inverter welding machine that runs on a conventional 220V network and welds metal with electrodes with a diameter of 3-4 mm.

I would like to add that such work should be undertaken by a person who has at least a little idea how to use specialized equipment, and who has little practical skills in using such tools.

Tools and equipment

• Scaffolding;
• Powerful angle grinder;
• Perforator or powerful drill;
• Plumb;
• Construction level;
• Inverter welding machine;
• Welding helmet (it is recommended to choose a mask of the "Chameleon" type);
• Welding gloves and preferably a welding suit;
• Two cutting wheels for metal;
• Cutting wheels for concrete, one of which has a maximum diameter (photo 3 and 4);
• Drill for metal d=8.5 mm;
• Drill for concrete d=8 mm;
• MP3 electrodes with a diameter of 3 mm, although it is possible to work with electrodes of 4 mm;
• Hammer;
• Bit;
• 13 open-end wrench for anchor bolts;
• Plastic film to protect the garage from dust;
• Respirator to protect the respiratory tract;
• Special glasses that protect the eyes from dust and small pebbles that form when making channels for a new gate frame;
• Clothing that maximally protects parts of the body from dust.

materials

• Corner with a shelf width of 40-75 mm for building the door frame (focus on the corner from which the frame is already made);
• Corner with a shelf width of 30-35 mm for the gate frame;
• Sheet scraps 2-2.5 mm thick.

The amount of rolled metal and sheet dimensions are calculated based on the area by which the gate will increase.

Procedure for building gates

The scaffolding is firmly and stably installed.

The contour of the new frame of the garage door is outlined.

Attached inside the garage polyethylene film in such a way as to prevent dust generated during operation from entering the room.

The corner prepared for building up the gate frame is cut, with a note of each segment about its location in the structure.

A cut is being made brickwork garage walls along the contour of the new door frame, first outside the garage. It is better to cut the wall horizontally along the seam located between the bricks (photo 5), which will facilitate the even laying of the channel and the further removal of the excess masonry array.

Photo 5. Sawing a masonry seam

The vertical cut is made along the outlined contour (photo 6) with a maximum recess into the existing part of the frame for ease of installation new design(photo 7).

The sufficiency of the depth of the strobe is checked by the segment remaining when cutting the corner with a shelf width of 40-75 mm (photo 8).

After completing the cut from the outside (photo 9), the sections of the corner for the frame are installed (photo 10) with careful welding of the seams at the junction of the segments (photo 11). When installing corner segments, it is advisable to check their location using a plumb line and a building level. After checking, the structural elements are fixed in some way, after which the seams are welded. In the case of the enlargement shown in the photographs, the gate was installed incorrectly during the construction of the garage, which had to be compensated by adjusting the newly created frame and sash construction, which will be especially noticeable in the photographs with the already enlarged gate. When performing welding work, it is recommended to have a fire extinguishing agent nearby.

For better attachment to the existing masonry of the structure being created, it is advisable to use anchor expansion bolts (photo 12).

The diameter of the bolts used is 8 mm with a length of 60 mm (photo 13). It is enough to fix the horizontal segment of the corner in four places. First, a hole in the corner to the brickwork is drilled with an 8.5 mm metal drill, and then the hole for the anchor bolt is deepened with an 8 mm drill for concrete to the desired depth. After that, insert anchor bolts, and the structure is attached to the wall.

After assembling and fixing the new structure from the outside, the necessary wall cuts are made from the inside, after which the elements of the gate frame are assembled in the same order and fastened from the inside.

The next stage is the preparation of parts for building up the sashes. To do this, cutting the existing sheets and cutting the corner with a shelf width of 30-35 mm into segments of the required length is performed.

Next, the fabric of the stackable section of each of the gate leaves is assembled. The assembled sections of the canvases are butt-welded from above to the gate leaves, and for fixing they are attached to a new section of the frame spot welding in several places (photo 14).

After that, excess brick is removed from the inside of the garage, gently chipping when using chisel and hammer tools. Before extracting excess sections of the wall, it is also necessary to fix the inner part of the stackable structure of the gate frame with anchor bolts (photo 15).

When the unnecessary pieces of the wall are removed, the frame structure is additionally strengthened and the extension part of the gate leaves is reinforced with the frame (photo 16). All new structural elements that increase the size of the gate are thoroughly welded, because the strength of the finished product depends on this.

The lower locks of the gate are fitted in place when new elements are added to the existing frame (photo 17). Then the floor is poured to the required level, or the gate frame is completely built up from below.

The upper locks of the gate are built up and adjusted according to top edge enlarged frame (photo 18).

WITH outer side gate upper loops due to the increased size of the canvases, they are cut and welded higher (photos 19 and 20).

The final step is painting the gate with special paint (photo 21). It is recommended to use a coloring composition that performs three functions - the paint replaces the primer, if necessary, converts rust and creates a paintwork protective layer on metal.

If a person has little skills in working with a special tool for concrete and has an idea about welding work, then he will be able to build the gate on his own, thus saving significant funds from the family budget.

For work, you will need a brick, channel, water and the garage door itself. As you can see, nothing special. When everything is at hand, you can begin to work.

Getting Started

Consider a situation where it becomes necessary to maintain the current level of the garage, as well as raising its gate. Let's consider the step-by-step execution of the operation. First, the garage door must be removed, then release the frame. Next, we remove several rows of bricks directly above the opening and raise the gate itself. At the end, in the lower section, you can raise the backfill and return the structure to its original position.

Now let's take a closer look, how to raise garage doors. Before removing them from the hinges, wash the mortar between the bricks of the row to which you will remove them, and install a channel or at least a reliable corner in its place. This operation must be carried out before lifting the garage door. So you can save the structure of the building from destruction, otherwise the consequences can be the most sad. Using anchor bolts, securely fix the selected channel or corner.

Other possible problems

Sometimes the difficulty may lie in the height of the garage door. In this case, the problem becomes more complicated, since its elimination will require certain experience and skills in the construction field. The solution we offer is designed for brick caravans. Above you can read detailed description actions, for this it is necessary to knock out one or two rows of masonry. After that, it is required to strengthen the resulting slope, after which the frame itself rises to the required height.

Let's summarize. There are various ways to solve the problem of raising the garage door. You can choose the most best option for your situation. I would like to repeat that the simplest and easy method to increase the clearance between the garage door and the floor is to cut them with a grinder.

Sometimes, after raising the gate by one or two bricks, the gap between them and the floor increases significantly. You can get rid of this problem different ways. One of them is concrete. You can also install a threshold. In any case, make sure that the slope is directed from the garage to the street. If this is not done, water during the rain will flow into the garage, filling it with dampness. And this, as you know, is very harmful to the car and the room itself.

There is a proverb "I passed the sopromat, I passed everything." And yet, some garage "experts" like to assure that they made "hard gates". Competent engineers are aware of a simple truth - "hard metal structures No", and a shipbuilding engineer, having heard about the strength of materials, will grin and say that "Strength of materials is a special case of Structural Mechanics, in which movement is not taken into account." This is us to the question of why it is sometimes necessary to raise the garage door. Now a little more detail on how to do this.

The main reasons for changing the geometry of the gate, or opening

General fatigue of the metal, settlement of the hinges, natural deformations upon completion of installation, settlement of the opening (the frame in which the gate is mounted) after different reasons, some other factors (for example, in hot, cloudless weather a couple of years ago there were problems of thermal deformations of metal structures).

External causes that do not depend on the material part. We bought a car higher - it doesn’t fit in dimensions, they made a mistake in the lower gap - in winter the gate is extremely difficult to open, one of the walls of the garage sank more, which caused the opening to skew, and others that are sometimes difficult to foresee.

In each of these cases, the decision is made individually, but we will consider several simple ways, which are available with a simple tool with an assistant.

Ways to raise (correct the geometry) of the gate

1. Sagging hinges, (the gate is deformed, or something else). To raise (for example, one sash) you can use a spacer washer. We remove the sash from the hinges, put a washer of the required thickness on the axis of the lower hinge, return the sash to its place. Sometimes it is difficult to pick up the puck, then we put a ball of a suitable diameter into the loop where the hole is. This method allows you to correct small distortions of the leaves, slightly raise the gate, and facilitate movement on the loop. Very important! The material of the washer and ball must be of a harder alloy than the loop itself!
2. The need to change the distance from ground level to the bottom of the wings. The easiest way is to cut off the lower part with a grinder, then fix the rubber strip to close the gap. Applicable if the sheathing sheet protrudes beyond the lower frame beams. If the gate is mounted so that the lower beam is at ground level, you will first need to cut the beam, then the metal, weld the beam in place. By the way, in our practice there are structures where the lower part (about 10 cm) is mounted on hinges, and when the gate is opened, it can be folded back.
3. The skew of the valves, due to the deformation of the opening. If you do not touch the opening, then the easiest way to determine the skew zone (as a rule, the sashes do not close in the upper or lower part), on the sash that does not give a bow, cut the horizontal beam, cut down a few mm. With effort (you may need a jack), we press the vertical beam of the frame - we weld it. Up to gaps of 7-12 mm deformation sheet metal will be invisible. We must weld the place of welding with an additional metal strip, since residual deformations will occur here! If you do not strengthen this place, the welding seam will simply break over time.
4. The need to increase the height of the opening. The most difficult case, which will take time, the ability to lay bricks, additional equipment. How to do this can be found on construction sites. We will consider a situation where the problem was solved more simply.

An example of a simple solution in a difficult situation

So, the new car did not pass through the dimensions of the upper part of the garage opening. 6-7 cm across the width of the car itself, 14 cm on the right - on the left, at the installation sites of the roof rails (by the way, one of the most common causes when you need to raise the gate in height!).

Some garage craftsmen immediately advised dismantling the upper part of the opening (reducing the number of rows of bricks is a common approach), re-scalding the frame, thus increasing the height of the opening. In fact, it is very difficult to raise the entire upper part by 14 cm (2.5 rows of bricks), but this was not required. How the problem was solved.

1. In the floor of the garage (concrete, as well as a race with a slope of about 2 meters long), grooves were hollowed out with a width of 2 - 2.5 tires each, a depth of 10 cm. . The bottom of the track was covered with corrugated metal fixed to the floor.
2. On the example of another car (garage cooperatives are good because there will always be almost the same car - in this case without roof rails). Take into account the difference in tire height. We determined the gap between the roof of the car and the upper frame in the most unloaded state - 7 cm.
3. On the left and right, in the upper part of the opening, 60 cm of the channel were cut out (the middle part was supported with beams just in case). They knocked out several bricks, and scalded the resulting U-shaped slots with a channel, which was fixed into a brick.
4. We checked the smooth check-in and check-out on the right car, made sure that everything was done correctly.
5. After that, I had to lift the necessary sheets a little, since the gates stopped closing these holes, which was done on the spot, after the wings had already been put in place.

This work was completed. They took three days, it took the help of a neighbor in the garages, it was not necessary to suffer with the task of how to raise the entire upper part of the frame (at the same time increasing the gate).

We hope that when you face a similar problem, this article will help you be smart, use simple ways solutions, rather than trying to solve the problem head-on, as experts from the Internet advise.

Garage doors endure heavy loads all the time. Due to their weight and wind gusts, they are subject to subsidence and arching. If the gate frame is deformed, it will not be possible to close the garage. In this case, many motorists are wondering how to raise the gate in the garage. In addition, execute this procedure may be needed in the event of a change of vehicle.

Raising the garage door may be required in the following cases:

• the foundation base sank along with the wall, therefore, the possibility of opening the wings disappeared, since their bottom is hooked onto the blind area;
• the gate hinges have been deformed or they have undergone significant wear, the sashes have tilted;
• the size of the garage door opening does not allow parking a car with a high ground clearance or a high seating position (Gazelle, UAZ-Patriot).

Gate lifting methods

There are different methods for lifting brick garage doors. It should be noted that when using certain methods, it may be necessary to remove the door from the hinges.

Repair washers

If the gate leaves are deformed due to the sagging of a pair of hinges, the following recommendations should be followed:

1. To raise the lowered sash, you need to install adjustment washers. The thickness is chosen taking into account the depth to which the loops sag.
2. To install the washer, it is necessary to remove the sash from the hinges, put the washer, return the sash to its place.
3. If it is not possible to use a washer right size, you can install an additional ball in the loop.

Reducing the headroom (raising the frame)

One of the hardest methods. The heavy steel structure is fixed with concrete, therefore, before lifting it, it is necessary to dismantle the gate leaves. If the foundation subsided, it is required to remove 1-2 bricks from the masonry (depending on the height of the rise). By means of a perforator or a special hammer with a chisel, it is necessary to remove the concrete from under the racks of the frame and the threshold beam located on the side.

With the help of a crowbar inserted under the central part of the frame, it rises to a small height. A wedge is inserted, then the procedure is repeated for the sides of the frame. Side wedges are driven in with opposite side threshold beams. After the gap between the frame and the ground increases to five or six centimeters, you need to use a rolling jack that can lift a weight of up to five tons. By means of a jack, a further raising of the frame is carried out.

Similarly, the frame beam located on top is raised. After a part of the brickwork is knocked out, a cut is made of the vertically placed racks and the top of the frame. The cut is carried out above the places where the loops are fixed.

The mass of the cut part of the frame does not exceed seventy kilograms. It can be lifted with a standard jack, which is installed on the threshold. A log / beam is installed between the plank located on top and the jack. After that, the ascent to required level.

Change threshold level

Using this method no need to dismantle the gate. It is not recommended to use this method if the bottom of the frame is almost at ground level. It will be necessary to mount horizontally placed spacers (for temporary fixing of the frame). The gate leaves open, after which the bottom of the frame is removed.

After that, a part of the threshold is knocked out. Then the bottom of the frame, by welding, returns to its place, the spacers are pulled out. Next, you need to fill the threshold with a cement solution.

cut the canvas

If the wings began to touch the earth's surface, and the gate is difficult to open, you can cut the bottom with a grinder. To eliminate the gap that will appear after trimming, you can fix at the bottom rubber compressor or a piece of hose.

Restoration of a deformed opening

If the opening was not made correctly during the construction of the garage, lateral twisting of the sash may occur. main reason deformation - a frame beam located on top. You need to find the stress point in this beam.

If you tap the beam along its entire length, you can find the stress point. In it, the material of the beam begins to oscillate. Cut this place with a grinder, using welding machine install a stiffening bar.

Enlarge garage door project

This method is used infrequently, as it is very laborious.

Height

First, the gate beam located at the top is dismantled. The slab is raised by means of several jacks installed along its edges. Platforms must be placed on and under the jacks so that they stand firmly on the floor. A metal beam is placed on the upper platform, which serves as an emphasis.

The plate must be lifted slowly (each edge ten centimeters at a time). In the gap that appears, it is required to put two bricks or metal corners.

Each plate in turn rises to the required level. After that, brick laying is done under the raised roof.

Wide

To increase the width of the opening, you will need to mount a horizontal beam of 2 corners (shelf width - seventy-five millimeters). It is required to create markings on the front wall above the opening.

By means of a perforator, a hole is created in the wall surface with a width of eight millimeters and a depth equal to the width of the corner shelf. A hole is drilled from the inside of the wall. 3 parts are cut off from the corner (along the dimension line), recessed into the created hole and welded with the letter “P”.

Similarly, work is done with outside wall surface. To prevent deformation of the formed frame, it is necessary to increase the strength indicators and rigidity by welding jumpers (transversely).
