Foundation for sliding gates

Nowadays, many types of gates are produced, but the most popular sliding gates. This design is very convenient in operation, the gate works according to this principle: 2 road wheels are placed on the foundation, the lower part of the gate is a beam that works as a guide.

Supports perceive the load from the weight of the gate, and allow their doors to move. The supports are fixed using embedded bolts. You can use this design without restrictions throughout the year.

The main part of any sliding gates is carts, with rollers allowing the door leaf to move, they are based on a reinforced foundation poured below the freezing depth of the soil. The foundation for this design is made special, for this reason, first of all, you need to calculate the dimensions of the pit, mark it and dig it.

Next, a mortgage is installed, so that one side of the channel fits snugly against the support post. When all the calculations are done and the mortgage is correctly placed in the pit, pour concrete and

set the gate.

You can open and close them either manually or using automatic devices. The most important for this design is the strength of the installation. Installation of the base and frame made with errors will most likely lead to malfunctions of the automatic system. For this reason, sliding gates are installed only on a special foundation.

Site selection

Preparation begins with the selection of a suitable site for the foundation. Considering that when opening the door of the structure, any side will move, the foundation must be continued from the same side of the gate opening. It is poured along the fence, from the inside of the territory.

Having decided in which direction the gates will move, prepare a site for the trench. Shrubs and trees should not grow on it - the roots after some time will surely damage the concrete monolith.

Training

An unusual foundation is made for sliding gates, and first of all it is necessary - to calculate the sizes and choose a suitable site for digging a trench. After calculating the dimensions and strength of the foundation, a trench is prepared, it should be 30 cm deeper than the level of freezing of the soil. After that, they are made of channels and a mortgage is mounted.

The channel is welded in a U-shaped design. After installation of the embedded structure, it is necessary to place reinforcement rods in the trench to increase the strength and reliability of the structure. Installation is carried out so that the side parts of the channel are as close as possible to the support column. After proper installation of the mortgage, you can begin concreting the foundation.

During all work, you must use a pre-prepared design drawing. This will protect against errors in the calculations on the ground. The immediate function of the foundation is to hold the cantilever units on which the entire structure rests. The foundation must be longer than the width of the gate.

Foundation process

In a dug trench, it is necessary to make a reinforcing cage. The fittings are connected by welding or knitted with wire, the main thing is that the skeleton of the foundation is securely fixed.

Sliding gates

This part of the structure is made of a channel 20 cm wide, equal in length to the foundation trench, and use reinforcement with a cross section of 12 mm to combine parts of the structure and also to create a reinforcing frame. To the prepared channel vertically using electric welding fasten pieces of reinforcement about 1 m long.

The assembled structure is lowered into the trench, directed downward by reinforcement, making sure that the channel side is adjacent to the support column and is located horizontally. It is important to correctly set the upper edge of the channel, this affects the presence and size of the gap between the road and the bottom of the gate. If it is necessary to install additional posts, they are dug into the ground and fixed to the embedded element.

The trench is poured with concrete solution so that the upper part of the channel remains clean. Usually, depending on the weather, the solution sets in 6-7 days. The reinforcing cage in the trench is placed horizontally.

Its upper part must be located below the soil surface by 11-12 cm. It is not difficult to prepare a concrete mortar for the foundation, the ratio of components: 6 measures of sand per 2 measures of cement, mix the solution to the sour cream consistency.

To strengthen the entire structure can be in concrete mortar add crushed stone. In this case, the proportions of the solution are the same, but 2 measures of crushed stone are added to it. Concrete must be poured carefully, making sure that the reinforcing cage does not move. The solution in the trench must be poured in one step into 1/2 pit. This method of concreting will ensure reliable fixation of the reinforcement.

After this, the transverse channels are fastened, 3 of them should be in the reinforcing cage. It is imperative to align the channel vertically and horizontally. After which it is welded to the reinforcement and poured with mortar, as a result of the work done, you will get a foundation, for stability reinforced by 3 channels located across the trench.

The level of the carriageway should be located 7 cm higher than the concrete channels of the channel. We must not forget that during the pouring of the foundation it is convenient to lay an electric cable for connecting automatic devices.

Foundation on stilts

If the soil on the site can sag, it is swampy or clay, it is better to make pile foundation. Such a basis is:

  1. Screw.
  2. Monolithic.

Screw metal piles are the best option in terms of labor and cash costs. So that this design can be used as long as possible, it is protected with anticorrosive substances or poured with concrete.

While creating monolithic foundation reinforced poles are immersed from the piles into the soil, which are necessary as a support for the channel. Separate piles fasten together with a reinforced concrete belt.

If the fence posts are not able to replace the supports for the gate, then prepare the pit into which the pole is installed.

Gate setting

Installation of the door leaf is carried out in stages:

  1. Marking the necessary space for moving the sliding sash.
  2. Production of roller trolleys.
  3. Calculation of the limits of movement of the rollers.
  4. Assembly.
  5. Adjusting the door leaf and checking the operation of the roller bearings.
  6. End roller mount.
  7. Installing the guide bracket.
  8. Mating support device.
  9. Covering the door frame.
  10. Mounting catchers and the necessary automation.

In the manufacture of sliding gates, a calculation is made of the place for movement and their installation. During the assembly of the structure, they are installed in profile and slightly moved towards the center of the mortgage, the door leaf is installed strictly vertically on them.

A response post is necessary for attaching catchers, and at the same time makes it possible to cover the resulting technological gap. Mount it tightly and fix, securing to the fence post opposite the embedded element.

The door leaf can be sheathed using various materials, for example, corrugated board or wood. The method of plating is chosen taking into account the design of the structure and material.

Installing Catchers

One of the stages of completing the installation of sliding gates is the installation of special catchers. One of these elements, located at the bottom of the gate, makes it possible, with the gate closed, to some extent reduce the load that is transmitted from the roller bearings. To calculate its location, it is necessary to completely close the leaf of the sliding gate and connect it to the end roller.

The trap located in the upper part of the structure makes it possible to prevent the swinging of the gate during strong winds. Its installation is carried out at the height of the protective corners, and keep in mind that the corners when the gate is closed must be in contact with the brackets of the trap located at the top of the gate.

Installation of automatic devices

The automation is installed last, the movement of the sash is done by means of gear racks. They are sold in parts of 1 m, complete with a special mount, fasten the rails to the supporting profile. When installing automation on a sliding gate yourself, you need to know that for their operation not only gear racks will be required, but also a special key, a beacon, a remote control and an electric drive with gear.

Installation of these elements is carried out, focusing on the instructions supplied with the equipment. If it is difficult to independently carry out this work, it is better to invite an experienced electrician.
