RU48864U1 - FACIAL WALL STONE - Google Patents

Abstract

The utility model relates to the field of construction and can be used in the manufacture of concrete facial wall stones for wall cladding for various purposes. The technical result, which consists in improving the decorative qualities of wall cladding while reducing its cost, is achieved due to the fact that along the perimeter of its front side on the upper and side sides there are bevels towards the rear side.

Description

The proposed utility model relates to the field of construction, in particular, to the production of wall stones intended for wall cladding in both residential and public buildings (hereinafter referred to as face stones).

To improve the decorative quality of the walls, their outer surfaces are laid out from special stones that differ from ordinary stones either by the increased quality of the facial faces, or by their special coating, or by giving them a decorative texture [1]. It should be noted that in any case, facial stones are significantly more expensive than ordinary ones, in particular, because the cost of the coloring matter is a significant fraction of the cost of the whole stone. Therefore, it is necessary to solve two problems: reducing the cost of facial stones and ensuring their reliable connection with the main masonry.

Face stones are known that are made in droves in various ways and from various materials (ceramic, concrete, composite materials) [2]. In accordance with this standard, they have the dimensions of ordinary stones, but differ from them in their color and texture. Such face stones are firmly connected to the wall, because they have a wide base, but have considerable cost, since the entire mass of the brick is subjected to staining. An additional drawback of the use of these stones is the need to increase the size of the foundation for them, which with significant dimensions of the building can cause a significant increase in the cost of construction.

Known facing the outer surface of the wall with a relatively thin front tile [3] (prototype). To grip the wall using nests (shallow blind holes) on the upper face and trapezoidal protrusions on the rear face. In this case, mounting hooks embedded in the wall go into the indicated slots. At the same time, the cost of facing is minimized,

the adhesion force of the cladding to the wall increases, but with this design the decorative qualities of the wall are low.

It should be noted that all of the above facial stones are bonded to the wall to be faced and to each other using a solution. For technological reasons, mortar joints are relatively thick (10-15 mm), which spoils the appearance of the facade. In addition, when facing, tiles are pressed into the solution, from this part of the solution inevitably falls on the external surface, almost unavoidable smudges of the solution are formed, which reduces the aesthetic properties of the building.

To eliminate this drawback, a face stone is proposed, the shape of which is shown in FIG.

Here: 1 - the front face of the stone;

2 - the back face of the stone;

3 - beveled side faces;

4 - beveled upper face;

5 - socket on the upper edge for mounting hooks;

6 - protrusion on the rear face.

The front stone around the entire perimeter of the front edge 1 (except for the lower side) has bevels towards the rear edge: on the sides - pos. 3, on the upper side - pos. 4. In this regard, the conditions H ₁ <H and B ₁ <B are satisfied. Elements 5 and 6 are similar to the corresponding elements of the prototype.

To explain the purpose of the bevels in figure 2 shows a fragment of the lining of the proposed stone.

Here 7 is the proposed face stone;

8 - facing wall;

9 - solution;

10 - mounting hooks.

When laying the facing with the proposed stone 7 of the wall 8, as already noted, facial stones are pressed into the solution 9. The extruded mass of the solution, in the presence of bevels, flows into the cavities formed behind them, which eliminates the ingress of the solution onto the front surface. 2 in

only a bevel falls on the upper side of the front stone, however, it is obvious that the same cavities form behind the bevels on the sides of the front face.

The presence of the proposed bevels does not interfere with the implementation of the front stones of known elements that increase adhesion to the wall: nests on the upper face and protrusions on the rear face. Moreover, the presence of bevels allows seamless cladding even in the presence of reinforcement, as shown in Fig.2.

It can be seen that the reinforcement 10 is completely hidden behind the protrusions and does not interfere with the seamless lining. As a result, the decorative qualities of the cladding are not violated.

In order to ensure that the reinforcement, even with a significant cross-section, does not violate the seamlessness of the masonry, it is proposed for its recession to perform on the upper face of the trough connecting the sockets with the rear face, as shown in Fig. 3, where item 11 is the proposed trough.

We also note that, having the above advantages, wall cladding from the proposed stones simplifies the technological process, since it eliminates seams and, therefore, does not require the bricklayer to manually ensure the same thickness of the seam throughout the entire masonry. At the same time, the cost of work is reduced due to the use of masons of lower qualifications and the elimination of the need for finishing finishing operations to remove traces of mortar.
