Description

The utility model relates to construction, namely to the construction of reinforced concrete walls, mainly external, using fixed formwork in the form of blocks, in particular polystyrene foam.

Monolithic walls of buildings or structures using prefabricated wall elements in the cavities of which reinforcement and concrete pouring are located are known, for example, from the following sources: Housing Construction magazine, No. 7, 1998, p.2-3; the magazine "Housing", No. 2, 2002, p.20; RF patent No. 2190922 E 04 B 2/84, 1998; RF patent No. 2052038 E 04 B 2/28, 1996; RF patent No. 2402 E 04 G 11/00, 1996.

The closest analogue in terms of the number of common features can be considered a monolithic wall according to the source - the Zhilishnoy stroitelstvo magazine, No. 7, 1998, p.2-3, in which the monolithic wall contains polystyrene foam blocks of fixed formwork, vertical reinforcement and concrete pouring in their cavities .

The main disadvantage of such a monolithic wall is the high complexity of its construction. This is due to the implementation of a large amount of work on the connection of reinforcing bars into spatial frames to the height of the wall, the need to ensure the strength and stability of such extended vertical frames. At the same time, significant labor costs for lifting blocks of fixed formwork to the mark of the upper end of these frames and their subsequent lowering along the vertical reinforcement.

The utility model is aimed at simplifying the construction of a monolithic wall.

The technical result that can be achieved using a utility model is to reduce the complexity of the construction of a monolithic wall.

For this, according to the utility model, the vertical reinforcement is made of sections, the height of each of which is equal to the height of one to five blocks of fixed formwork, the corresponding ends of the previous and next sections of vertical reinforcement overlapping with concrete layer-by-layer casting of the cavities of the fixed formwork blocks along the monolithic height walls.

In this case, the installation of vertical reinforcement, the installation of fixed formwork blocks and filling their cavities with concrete mix is carried out in layers at the height of the monolithic wall, which eliminates the time-consuming work of connecting the reinforcing bars into stable and durable spatial frames to the wall height, and also reduces the labor required to install the blocks fixed formwork. The strength and stability of vertical reinforcement in a utility model is created by the location of the corresponding ends of the previous and next lap sections.

The use of vertical reinforcement sections of the height of one block of fixed formwork unnecessarily increases the number of cycles for the erection of a monolithic wall and, consequently, increases the complexity of its construction.

When the height of the sections of vertical reinforcement is more than five blocks of fixed formwork, the sizes of these sections increase, the installation of horizontal rods is required, the height of the blocks of fixed formwork increases, that is, the laboriousness of erecting a monolithic wall increases.

According to claim 2 of the formula, a monolithic wall may additionally contain horizontally oriented reinforcement installed at

layer-by-layer concrete casting of cavities of fixed formwork blocks along the height of a monolithic wall. This increases its strength if necessary.

The utility model is illustrated by an example implementation. In FIG. the drawing shows a patentable monolithic wall in axonometric projection.

The monolithic wall of a building or structure contains polystyrene foam blocks 1 of fixed formwork, vertical reinforcement and concrete pouring located in their cavities 2. The vertical reinforcement is made of sections 3, 4, the height of each of which is approximately the height of 1.5 blocks 1. The lower ends of section 4 and the upper ends of the vertical reinforcement portion 3 are overlapped.

A monolithic wall is erected as follows. Mount section 3 of the vertical reinforcement. Then, two rows of blocks 1 are installed so that the section 3 of the vertical reinforcement is located in the cavities of the blocks 1. Next, these cavities of the blocks 1 are filled with concrete mixture 2. Thus, a layer-by-layer concrete pouring is made along the height of the wall of one of the sections.

Then make the next section on the height of the wall. To do this, in the uncured concrete mixture in the cavities of the blocks 1 set the lower ends of the next section 4 of vertical reinforcement. In this case, the lower ends of section 4 and the upper ends of the previous section 3 of vertical reinforcement are lapped. Section 4 of the vertical reinforcement also has a height equal to a height of approximately 1.5 blocks 1. Two rows of blocks 1 are installed along the height of section 4 and their cavities are filled with concrete mixture. In this case, a second layer-by-layer section is formed along the height of the wall. These operations are repeated until the wall is erected over its entire height. If necessary, during layer-by-layer concrete pouring, it can be laid between sections in not hardened

concrete mix horizontally oriented reinforcement in the form of rods 5, which increases the strength of a monolithic wall.

Thus, a monolithic wall is proposed, the construction of which does not require the implementation of connecting work with fittings, reduces the volume of lifting and transport work when installing blocks of fixed formwork. Patented utility model reduces laboriousness and simplifies the construction of a monolithic wall of a building or structure.
