In our country, sliding gates have gained great popularity since the Soviet era, when such an opening system was installed at most enterprises. Now, such gates are installed on the private plots and fences of cottage settlements. The sliding doors have become very popular due to the ergonomic design, which saves space.
Make a sliding gate for your site can each. This will require some time from you, but the self-made gates will cost less than those ordered by a specialized company.
To understand how the sliding gate is constructed, it is enough to study their drawing. In such a system there are no complex or ingenious elements. Everything is simple and reliable.
Sliding gates are installed inside the welded frame, into which the open door leaf leaves. Roller bearings of closed type are installed in the frame, which makes it easier to open and close the gate. In this case, the carriages of the rollers, being inside the frame, are reliably protected from precipitation and external influence, which allows to reduce maintenance to a minimum( lubrication of bearings only when the door is installed) and extend the service life to an average of 12 years.
For finishing the gate can be used any material-chipboard, lining, metal siding, solid steel sheet or any other.
From your wishes and financial possibilities it depends on whether the gate will be moved manually or using automation systems. Also it is necessary to decide for what purposes the gate will be used: as a front entrance, fire( evacuation) exit or as a spare in case of malfunctions of the main gate. All this determines the size, appearance and cost of the installation of the gate.
1. Installation of the future gate frame
The first step in the installation process is the installation of the opening of the future gate. For this purpose, poles made of two steel pipes, bricks or wooden beams are installed. Pillars should go to the ground at least a meter, this depth is frozen in winter by the soil. The pillars are installed in the pit in this depth, leveled and filled with cement mortar.
It takes about a week to completely dry the solution.
2. Foundation for the gates
A foundation is also required for installing the frame. For its manufacture, we take a channel 20 mm wide and a reinforcement with a diameter of 15 mm. The armature is cut into meter pieces and welded to the channel vertically. As a result, you should get a design, like scaffolding.
Under the foundation a swath of a pit, the length of which is equal to half the width of the door opening. The width of the pit is 40 cm, the depth is not less than one meter.
A hole is placed in the pit from a reinforcement and a channel. It should be noted that the leveling of the channel relative to the ground level determines the width of the gap between the door leaf and the road. After placing the foundation of the foundation, the pit is poured with cement mortar and allowed to freeze.
. If you did it right, you will get an even metal pad, on which guides for the gate will be installed later.
3. Support frame
For the manufacture of the gate frame, we require metal pipes with a diameter of 30 to 60 mm.pipes must be cleaned of rust with a grinder or grinder, degrease and primer.
After the processing of the pipes is finished, proceed to weld the frame. On the finished frame of pipes fastened crate, from pipes of smaller diameter( for example, 20mm), which will be the basis for the plating. The paneling is attached to the door leaf by means of screws or rivets.
The location of the crate inside the frame is determined by how you want to trim the gate. With one-sided sheathing, the lath is at the edge of the frame, with the double lining in the center.
doors. When welding, make welds in 25 cm increments. This is the optimal distance for maximum structural strength.
After welding, all seams are compared by a Bulgarian, and the door leaf is re-primed and painted. When the paint dries, you can begin to sheathe the fabric with the selected material.
4. Installation of
guides The mounting of the gate itself begins with the fitting of the guides. Set the lower rollers, bearings and guides to the open position. Pay attention to the position of the first and last rollers, from them to the edge of the door leaf there should still be free space.
guides Place the upper guide rail on the rollers and level the rollers to level. After that, place the frame of the gate on the rollers and again set everything in level. If the frame is level, grab the roller platforms with welding to the foundation, weld the upper and lower catchers.
rollers The upper guide is attached to the previously installed posts, and the rollers are attached to it. If the poles are made of metal, you will not have any problems with welding. If the posts are brick or wooden, use anchors or mortgages from the reinforcement.
door leaf installation Roller carriages are recommended to be welded in easily accessible places to avoid problems with repair or replacement in the future.
door leaf installation The lower rollers, as already mentioned, are welded to their foundation by their platforms, and the upper rollers are fastened to the guide with bolts or welding. Variant with bolts allows you to replace the rollers if necessary, weld the same connections have to be cut and re-digested.
6. Assembling the upper rollers against lateral rolling
Instead of the guide beam, several vertical roller guides can be made from above. They are attached to the U-shaped profile with bolts. Such rollers will not allow the door leaf to swing and will act as a guide beam. The advantage of such a system is that in the doorway there are no barriers to the passage of high cars.
7. Installation of lower catcher
On the lower edge of the foundation, weld the lower catcher into which the door leaf will enter. Thus, an additional support point is created, which makes it possible to release the rollers from the load.
Experience shows that the manufacture of sliding doors on its own allows you to significantly save finances. The manufacture of the gate in the company would have cost twice as much. In addition, parts and structural elements are not a scarce commodity. With the proper observance of the installation technology, your self-made gates will last much longer than your branded doors.
