Abstract

FIELD: construction.

SUBSTANCE: invention relates the erection of walls of residential and civil buildings using fixed formwork. Wall fixed concrete formwork for erection of wall structures comprises the following combined and connected elements: ordinary block, angular block and additional angular block. The blocks are made of concrete. The ordinary block contains parallel outer front and rear longitudinal walls connected by two parallel partitions, whereas the upper surface of the partition has chamfers 15 mm high at an angle of 45 degrees, turning into a groove with a radius of 8 mm. A connecting stepped surface is made on the side surface of the walls. The angular block is an angular structure and comprises the first parallel outer front and rear longitudinal walls, which are located at an angle of 90 degrees to the second parallel outer front and rear longitudinal walls, while the first and second outer front and rear longitudinal walls are each connected by two parallel partitions. On the upper surfaces of the partitions, chamfers 15 mm high are made at an angle of 45 degrees, turning into a groove with a radius of 8 mm, a connecting stepped surface is made on the side surface of the walls. The additional block angular is a hollow cubic structure, consisting of four walls, each located at an angle of 90 degrees to each other whereas two of the walls are front and two are back. Mounting connecting surfaces are made on the side surface of the front walls, and chamfers 15 mm high at an angle of 45 degrees are made on the upper surface of the front walls, turning into a groove with a radius of 8 mm. Blocks are installed on the finished foundation using adhesive. After the erection and installing of 4-5 rows of blocks, the masonry is reinforced and the cavities of the block are filled with concrete mixture whereas 2 types of reinforcement are used: horizontal and vertical.

EFFECT: increased formwork strength; acceleration of its installation during the construction of buildings; reducing the material consumption for the wall structure.

Description

The claimed invention relates to the field of construction, namely the erection of walls of residential and civil buildings using fixed formwork.

Various fixed formworks are known from the prior art (for example, see utility model patent RF 131024, published 08/10/2013, RF patent 2525242, published 08/10/2014, etc.). However, the known solutions have a number of disadvantages, such as insufficient strength, a large thickness of the bearing wall, a long installation time during construction and the impossibility of building in seismically hazardous areas, etc.

The objective of the claimed invention is to eliminate the shortcomings of the prior art.

The technical result of the claimed invention is to provide:

- increasing the seismic resistance of buildings and structures;

- increasing the strength of the formwork;

- acceleration of its installation during the construction of buildings;

- reducing the material consumption of the wall structure and reducing the area of the foundation or increasing the internal area of \u200b\u200bthe house while maintaining the external dimensions of the building.

The stated problem is solved, and the technical result is achieved by means of the declared wall non-removable concrete formwork for the erection of wall structures (see Fig. 5), which contains combined and connected blocks made of concrete: an ordinary block, a partition block, a corner block and an additional corner block, at the same time, the ordinary block (see Fig. 1) contains parallel outer front and rear longitudinal walls connected by two parallel partitions, while on the upper surface of the partition there are chamfers 15 mm high at an angle of 45 degrees, turning into a groove with a radius of 8 mm, on the side surface of the walls is made connecting stepped surface;

the angular block (see Fig. 3) is an angular structure, and contains the first parallel outer front and rear longitudinal walls, which are located at an angle of 90 degrees to the second parallel outer front and rear longitudinal walls, while both the first and second outer the front and rear longitudinal walls, each, are connected by two parallel partitions, while on the upper surfaces of the partitions there are chamfers 15 mm high at an angle of 45 degrees, turning into a groove with a radius of 8 mm, a connecting stepped surface is made on the side surface of the walls; corner additional block (see Fig. 2) is a hollow cubic structure, consisting of four walls, each located at an angle of 90 degrees to each other, while two of the walls are front and two are rear, fastenings are made on the side surface of the front walls connecting surfaces, and on the upper surface of the front walls there are chamfers 15 mm high at an angle of 45 degrees, turning into a groove with a radius of 8 mm; partition block (see Fig. 4) contains parallel outer front and rear longitudinal walls connected by three parallel partitions, the first and third partitions are located at the ends of the longitudinal walls and have a stepped connecting surface - protruding from the front side and sunken from the back side, with In this case, a groove with a radius of 8 mm is made on the upper surface of the partition in the middle.

The blocks are laid on the finished foundation with glue (joint thickness 1-3 mm). When laying blocks, the masonry is reinforced, and 2 types of reinforcement are used - horizontal and vertical. Horizontal reinforcement is made of A500C reinforcement, 8 mm in diameter, and is laid in 2 rows every fourth row of masonry. Vertical reinforcement (A500C, diameter 8 mm) is laid vertically and in a checkerboard pattern.

After the erection and laying of several rows (4-5 rows) of blocks, the cavities of the block are filled with concrete mixture. After the concrete hardens, a reinforced concrete structure is obtained. Filling can be done both manually and with a concrete pump. When pouring concrete, vibration is produced.

For the construction of interior partitions, a partition block 120 mm thick is used, while there is no need to pour concrete inside and reinforce the masonry.

For the proper erection of masonry corners, corner blocks and corner additional blocks are used, which are alternately placed on top of each other, while there is no need to file the blocks to correctly form the corners of the building.

In addition, unlike other wall materials used, in this block there are no problems with fastening heavy objects to the wall, since the structural strength is very high.

When laying internal communications (such as electrics, heating pipes), there are no problems with block chasing, since the wall thickness is 40 mm, and the chasing thickness is always less, so the chasing depth does not reach the main concrete and reinforcement.

Thus, this wall has several advantages:

1) since the wall is monolithic and reinforced concrete, it can be used in seismically hazardous regions, unlike other structures (for example, brick or gas block, which have a thickness of 300-380 mm);

2) The thickness of the bearing wall is only 200mm. Saving wall thickness leads to a decrease in the material consumption of the wall structure and a decrease in the area of \u200b\u200bthe foundation or an increase in the internal area of \u200b\u200bthe house while maintaining the external dimensions of the building;

3) increased strength of the formwork and accelerated its installation during the construction of buildings.
