Description

The utility model is used in construction for the erection of building structures from concrete mix and the like hardening material, as well as for reinforced concrete sandwich structures.

An analogue is the reinforcement formwork unit, including walls reinforced with flat frames and united by reinforced partitions, characterized in that, in order to increase strength, each partition is reinforced with staple rods placed along its height and joined by vertical rods, the ends of the staple rods being connected to the horizontal rods of the overlap frames [patent for invention 1690551]

The disadvantage of this analogue is the complexity and high complexity in the manufacture of the block.

As a prototype, a fixed formwork unit was taken, including two flat-shaped elements - two formwork plates placed opposite each other, and clamps - structural steel stiffeners in the form of rectangles placed across between the plates and embedded side parts into the inner surface of the plates. Bottom block can be equipped with a horizontal slab formwork.

The disadvantage of the prototype is the low bearing capacity.

The objective of the utility model is to simplify the design of the block and ease of installation at the construction site.

The technical result is aimed at increasing the bearing capacity of the block, as well as reducing the complexity of formwork.

The technical result is achieved by the fact that the reinforcement formwork unit consists of two reinforced concrete formwork slabs connected by a stiffener made in the form of horizontal reinforcing rods connected to flat frames in the body of the formwork slabs, with metal knitting wire perpendicular to the plane of these plates.

If necessary, heat and sound insulating material can be installed, as well as the outer sides of the block formwork slabs during the manufacturing process can be lined with any facing material.

Also, formwork slabs can carry recesses for all necessary communications.

The essence of the utility model is illustrated by drawings.

In figure 1. The proposed block, axonometry is presented.

In figure 2. - two side views

In figure 3. - sections aa, bb

In figure 4. - a fragment of the wall from the proposed blocks, axonometry.

Figure 5 - reinforcement of the block, a perspective view.

Where 1 - reinforced concrete formwork slab, 2 - flat frame slab, 3 - connecting reinforced rods, 4 - knitting wire.

When assembling reinforcing formwork blocks at the construction site in the desired structures, they are fastened together by knitting wire 4 (Figure 4), which significantly reduces the complexity of formwork and allows you to lay all the necessary communications inside the structures.

At the construction site, at a level specified by the project, reinforced concrete zero (a site of a certain thickness) is poured, from which reinforcement reaches 50-60 cm of the desired diameter vertically, at a given distance, in one or two rows, in one or two rows. After additional marking, we install the blocks along the perimeter of the alleged walls, linking them together and the outgoing armature with a knitting wire until an intracavity wall is formed with a given height of the entire floor of the structure. Then, having laid the formwork and having connected the reinforcement of the ceiling (ceiling), the entire intracavitary structure, including the ceiling, is poured with concrete, thereby forming a spatially inextricable, monolithic, reinforced concrete structure of a homogeneous section. When assembling from blocks of a hollow wall, reinforcement is simultaneously tied into it. The vertical reinforcement is knitted so that after pouring the entire structure

concrete, she spoke on the next floor around the perimeter of the proposed walls no less than 50-60 cm. after monolithic concrete to a given strength. Next, they collect the next floor, etc.

After the construction of the structure, we get a single spatially inextricable, reinforced concrete monolithic structure of a homogeneous section from zero to the last floor, lined on the outside and bearing all the communications in its walls.

When building low-rise buildings on the principle of reinforced concrete sandwich construction, the assembly technology is the same. During the constructive formation of an intracavity wall to a predetermined height of the entire floor of the structure, the touch lines of the blocks with the inner hollow wall or outside with mastic are smeared. This is necessary in order to avoid the loss of penoizol. After the formation of the intracavity walls, the floor is covered with the design material so that it is possible to continue forming the intracavity walls of the structure, etc.
