Description

The invention relates to the field of construction, and in particular to devices designed for fastening to the overlap of the upper part of the external curtain wall of lightweight concrete blocks.

A device for attaching the upper part of a curtain wall of lightweight concrete blocks to the ceiling, described in the normals of typical nodes [1]. The device is a straight U-shaped strip, with pointed lower edges that are inserted into the hole in the floor slab, filled with an effective heater (thermal insert), and then clogged into the upper rows of masonry from lightweight concrete blocks. The disadvantages of the device are the following:

1) the design of the device allows it to be used only in places of overlap where thermal liners are provided, which makes it impossible to use it for a number of walls, for example, three-layer walls with an inner layer of light concrete blocks, in which thermal liners are usually located above the wall insulation layer;

2) when driving the strip into a lightweight concrete block to a depth of more than 150 mm, as practice shows, it partially splits, which leads to a significant decrease in the bearing capacity of the masonry fastener to overlap;

3) the design of the device eliminates the possibility of simultaneous masonry of walls from blocks on two or more floors, which reduces the manufacturability of the process and leads to an increase in the duration of construction.

It is also known a device for attaching the upper part of a curtain wall from lightweight concrete blocks to the ceiling, described in the regulations [2]. The device is a straight reinforcing bar, the upper part of which is hammered into the hole made in the overlap, and its lower part is brought into the vertical masonry seam of the upper row of masonry.

The disadvantages of the device are the following:

1) the design of the device necessitates the obligatory combination of a vertical seam with it, which reduces the manufacturability of the masonry process due to an increase in the volume of sawn blocks and leads to an increase in material consumption and construction time;

2) the combination of the vertical masonry seam with the core leads to the formation of excess thickness of the vertical seam, to reduce which it is necessary to make vertical cuts in the blocks, which also increases the duration of the masonry process;

3) as experience with the use of such core devices shows, it is practically very difficult to completely fill the vertical seam of the upper row of masonry with a solution, if it is combined with the core, which reduces the load-bearing capacity of the masonry fastener to overlap.

Also known is a device for attaching the upper part of a large-sized partition to the ceiling, described in the copyright certificate [3]. The device consists of a rigidly connected straight pin and an L-shaped plate. The upper part of the pin is hammered into the hole made in the overlap, and its lower part and the L-shaped plate rigidly connected to it are pressed to the upper part of the partition from two sides.

The disadvantages of the device are the following:

1) the design of the device eliminates the possibility of introducing it into the masonry, which leads to a decrease in the bearing capacity of the masonry fastening unit to the ceiling;

2) the design of the device necessitates additional finishing work, because on the trimmed surface of the fence go metal elements.

In all of these devices, there is no possibility of vertical movement of the part of the device that is fixed to overlap, relative to the part of the device that holds the upper part of the wall masonry, which leads to a decrease in the manufacturability of using these devices, because the upper part of the constructed masonry must be additionally straightened under the device to ensure their joint work.

The objective of the invention is to increase the load-bearing capacity and manufacturability of the device for attaching the outer wall to the ceiling, while ensuring the possibility of simultaneous masonry of the outer walls on two or more floors, as well as reducing the amount of work on the interior decoration of the wall.

This task is achieved due to the fact that the device for fastening the masonry of the outer wall to the ceiling, consisting of a retainer and a holder made in the form of a vertical plate with the possibility of its vertical movement relative to the retainer, which is made in the form of a corner, and in the lower part of its vertical shelf is made U -shaped bend, and in the holder a rectangular hole is made, edged along its lower edge with a cantilever plate located perpendicular to the holder and codirectional horizontal shelf , The upper edge of the opening is not disposed below the U-shaped bending, and the holder is arranged between the shelf and the vertical U-shaped contour. Moreover, the holder from the bottom of the rectangular hole is bent and the cantilever plate has a width and length equal to the width and height of the rectangular hole, respectively. In addition, a number of slit-like openings are made in the cantilever plate forming the lateral sides of the triangles, while sections of the cantilever plate limited by the area of such triangles are located below the plate and perpendicular to it. In addition, a hole is made in the horizontal shelf of the latch.

The invention is illustrated by drawings (Fig. 1, 2 and 3).

In FIG. 1 and 2 show axonometric images of the retainer and holder, figure 3 shows a perspective view of the device, in which:

1 - vertical plate;

2 - corner;

3 - U-shaped limb;

4 - a rectangular hole;

5 - cantilever plate;

6 - hole in the horizontal shelf of the latch;

7 - sections of the cantilever plate limited by slit-like openings;

8 - bend of the holder.

The specified problem is solved as follows. Before the masonry of the two upper rows of the outer curtain wall section, the latch (Fig. 1) is fixed to the ceiling using an anchor installed in the hole of the horizontal shelf. After laying on the wall section of the penultimate height row of blocks, the holder is hung on the U-shaped bend of the retainer (Fig. 2), so that the holder is placed between the vertical shelf of the retainer and its U-shaped limb (Fig. 3). Next, lower the cantilever plate of the holder on the upper bed of the block, while it is possible to vertically adjust the position of the holder relative to the specified masonry seam. By driving the triangular sections of the cantilever plate into the block, the holder is fixed in height. After that, a masonry mortar or adhesive mixture is applied to the bed of the block and the masonry is finished, i.e. stack the top row of blocks.

The technical result of the invention is that:

- thanks to the laying of the cantilever plate in the horizontal seam of the masonry and its connection with the block by means of triangular sections, as well as the bending of the holder, as a result of which its section located below the rectangular hole is pressed against the outer surface of the wall, the load-bearing capacity of the fastening unit of the outer wall to the ceiling increases ;

- due to the presence of the limb on the vertical shelf of the latch there is the possibility of vertical movement of the holder relative to the latch, which increases the manufacturability of the device mounting the outer wall to the ceiling;

- the proposed constructive solution of the device eliminates the presence of protruding parts on the inner surface of the wall, which, in turn, minimizes the amount of work on its decoration;

- the proposed constructive solution of the device allows its installation on two or more floors at the same time, which makes it possible to simultaneously conduct masonry on several floors.

Thus, the constructive solution of the device provides an increase in the bearing capacity and manufacturability of the device for attaching the external wall to the ceiling, while ensuring the possibility of simultaneously laying the external walls on two or more floors, as well as reducing the amount of work on the interior decoration of the wall.
