STONE WALL

The technical field to which the utility model relates.

The proposed utility model relates to the field of building elements in the form of blocks or another form for the construction of individual parts of building structures, namely, the construction of wall stones.

State of the art

Known wall stones, disclosed in GOST 6133-99 "Concrete wall stones. Technical conditions ”(hereinafter - [1]). Known stones when laying walls are connected with a solution of both horizontal and vertical joints, and their end walls can be both smooth and with protrusions for mortar keys.

Known technical solutions have several disadvantages. The quality of the masonry is very dependent on the qualifications of the bricklayer and the quality of the mortar. The weak point (in terms of quality) are vertical seams. With a liquid mortar or, conversely, a very thick mortar, and with insufficient qualification of a bricklayer, vertical seams may not be completely filled with mortar, and sometimes there is empty space. In addition, the density of the mortar is always less than the density of concrete vibropressed stone. All this leads to the fact that the walls, lined with famous stones, have a low level of sound insulation index of airborne noise Rw. So, for interroom walls, the required Rw ≥ 52 dB, which is not always possible when using known stones. One of the methods for solving this problem is to increase the thickness of the plastering of the walls. However, the proposed method leads to an increase in the complexity, material consumption and weight of wall structures.

Known wall stone, disclosed in the patent of the Russian Federation for utility model No. 100787, published December 27, 2010 (hereinafter - [2]). The known stone is made in the form of a rectangular parallelepiped and, to increase Rw, includes at least one vertical protrusion of arbitrary shape on one end wall and the same number of corresponding response grooves on the opposite end wall.

The known solution has the following disadvantage. When loosing adjacent stones (loose in masonry), or if a bricklayer wants to avoid cutting the stone to end the row, when the stones are “dispersed” with gaps, to avoid the need to insert an additional stone, cracks arise and the sound insulation of the wall decreases sharply. Rw, in this case, may turn out to be even less than that of walls made of known stones disclosed in [1].

Utility Model Implementation

In FIG. 1. presents a top view of an exemplary embodiment of the proposed utility model.

The wall stone (1) is made in the form of a rectangular parallelepiped, while one of the end walls (2a) includes a first vertical protrusion (3a) and a second vertical protrusion (3b), and the opposite end wall (2b) includes a first response a groove (4a) and a second return groove (4b). The stone (1) further comprises a first recess (5a) located between the first protrusion (3a) and the second protrusion (3b), and a second recess (5b) located between the first response groove (4a) and the second response groove (4b). In this case, the first response groove (4a) and the second response groove (4b) are slightly larger in size of the corresponding first protrusion (3a) and the second protrusion (3b). It will be apparent to those skilled in the art that the first recess (5a) is the space directly formed between the first protrusion (3a) and the second protrusion (3b) in the manufacture of stone (1), wherein the recess (5b) is purposefully formed. In addition, the first recess (5a) can also be called the first additional keyway (5a) or the keyway (5a), and, accordingly, the second recess (5b) can also be called the second additional keyway (5b) or the second keyway (5b). In an exemplary embodiment of the proposed utility model, the first protrusion (3a) and the second protrusion (3b) are made tapering in the direction from the end wall (2a), each of them has a trapezoidal shape. The first protrusion (3a) and the second protrusion (3b) are made along the entire height of the end wall (2a).

The wall stone (1) further includes a first internal cavity (6a) and a second internal cavity (6b). The wall stone (1) also contains an intermediate wall (7) or a partition located between the first cavity (6a) and the second cavity (6b) and preferably parallel to the first end wall (2a) and the second end wall (2b). In addition, the stone (1) wall additionally includes a chute (8) for reinforcing the masonry (for laying reinforcement), made on all transverse walls of the stone and passing along the surfaces of the transverse walls from the first end wall (2a) to the second end wall (2b ) and oriented along the longitudinal axis of the stone (1) of the wall, preferably parallel to it and perpendicular to the first end wall (2a).

The use of the above exemplary embodiment of a stone (1) wall is presented below with reference to FIG. 2.

In FIG. 2 is a top view of a masonry section formed by identical wall stones (1) — a series of wall stones (1).

Indices -a, -b, -c are added for ease of description of the masonry and are selected conditionally: stone (1a) - stone (1), relative to which the description is presented, i.e. the stone under consideration (1), stone (1b) - stone (1), preceding stone (1a) in the row of stones (1), stone (1c) - stone following stone (1a) in the row of stones. In order to simplify the drawing, some positions on it are not marked.

The end wall (2a) of the stone (1a) is connected to the end wall (2b) of the previous stone in the row (1b), and the end wall (2b) of the stone (1a) is connected to the end wall (2a) of the next stone in the row (1c). Preferably, the end walls (2a) and (2b) are brought into contact (in connection). In this case, the first protrusion (3a) of the stone (1a) is placed in the first mating groove (4a) of the previous stone (1b) and the second protrusion (3b) of the stone (1a) is placed in the second mating groove (4b) of the previous stone (1b). In addition, in the first mating groove (4a) of the stone (1a), a first protrusion (3a) of the subsequent stone (1c) is placed and in the second mating groove (4b) of the stone (1a), the second protrusion (3b) of the subsequent stone (1c) is placed. Thus, the first protrusion (3a) represents the first alignment protrusion (3a), the second protrusion (3b) represents the second alignment protrusion, the first response groove (4a) represents the first alignment groove, the second response groove (4b) represents the second alignment groove. The said protrusions (3a) and (3b) and the response grooves (4a) and (4b) orient the stone (1) in space, forming, when interacting with adjacent stones (1), tongue-and-groove joints, thereby reducing the requirements for the qualification of a bricklayer, and reduces the complexity of the work performed. In addition, the implementation of vertical joints without solvents also leads to a decrease in the complexity and material consumption, i.e. when laying, lay only a horizontal joint solution. In addition, in the path of the sound wave, in addition to plaster (if any), there is dense concrete (the same as the material of the whole stone), which allows you to get the specified Rw.

When joining stones (1), the recess (5a) of the stone (1a) and the recess (5b) of the previous stone (1b) form a closed cavity (9a), and the recess (5b) of the stone (1a) and the recess (5a) of the subsequent stone (1c) form respectively a closed cavity (9b). The cavity (9a) and the cavity (9b) are filled with a solution (liquid key). Filling the cavities (9a) and (9b) with a solution makes it possible to create reliable engagement of stones (1) with each other without gaps, which increases the reliability of the masonry formed by stones (1), and also significantly improves the soundproofing characteristics of the masonry.

The gutter (8), if necessary, can be used for laying reinforcement in cases where this is required in accordance with design decisions. In addition, the specialist in the field of technology it is obvious that the chute (8) can be performed on any given wall (face) of the stone (1) wall. The groove (8) can be made on a part of the wall surface, preferably, it completely intersects it.

It is obvious that the above description of the embodiment of the proposed utility model is given as an example and cannot be considered as a limitation. Other embodiments of certain features of the proposed utility model that are not presented in the above description with reference to the relevant figures and do not go beyond the nature and scope of the legal protection claimed by the utility model formula are obvious to a person skilled in the technical field. The detailed description above with reference to the accompanying drawings is given in order to explain the essence of the claimed utility model and provide examples of material and technical means that can serve to implement the features of the proposed technical solution. So, for example, the following are some possible alternative options for performing certain signs of the proposed technical solution.

In FIG. 3 shows a top view of an alternative embodiment of the proposed technical solution. Presented in FIG. 3, the embodiment of the proposed technical solution differs from the solution described above in that the shape of the first response groove (4a) and the second response groove (4b) are close to the shape of the first protrusion (3a) and the second (3b), respectively. In other words, the first response groove (4a) and the second response groove (4b) are made tapering into the stone (1). In addition, between the first protrusion (3a) and the second protrusion (3b), an additional recess (5c) is made.

It should be noted that as a stone (1) any wall stone known from the prior art can be used.

It is obvious that in other embodiments of the proposed utility model, the stone may contain at least two protrusions and at least two reciprocal grooves.

It is also obvious to a person skilled in the technical field that the shape and / or dimensions of at least one protrusion and / or at least one response groove can be made different from those shown in the figures. For example, it is preferable that at least one protrusion (3) is made tapering away from the end wall (2). The cross-section (for example, longitudinal) of at least one protrusion (3) may have a rectangular, trapezoidal, polygonal, barrel-shaped or any other form known from the prior art. At least one reciprocal groove (4) can be made tapering into the volume (inside) of the stone (1) wall and / or similar or matching in shape with at least one protrusion (3). In addition, the width of the at least one counter groove (4) may be greater than the width of the at least one protrusion (3), and the depth of the at least one counter groove (4) is greater than the height of the at least one groove (4). At the same time, at least one protrusion (3) and / or at least one reciprocal groove (4) can be made not vertical, but, for example, at an angle to one of the faces. It is also preferable, to simplify the manufacture, the proposed technical solution contained the same number of protrusions (3) and mating grooves (4) on the corresponding end walls (2) to form a gapless joint. In addition, the width of at least one groove is more than two times its depth.

In other embodiments, the stone may contain at least one cavity (6), while at least one cavity (6) can be made through and / or at least one cavity (6) can be made through. It will be apparent to those skilled in the art that the shape and / or dimensions of the cavities (6) may be different from those shown in the figures, for example, at least one cavity (6) may have a cylinder shape.

It will be apparent to those skilled in the art that in other embodiments of the proposed utility model, stone (1) contains at least one recess (5), for example, intended to be filled with a solution (liquid key).

The proposed technical solution can be made from a material known from the prior art, for example, dense concrete.

The proposed utility model allows to increase the air noise insulation index Rw due to the fact that the protrusions (3) made of dense concrete act as barriers to the sound wave path, and additional recesses (5) allow better filling of the space between the stones, which will provide additional sound insulation.

Additionally, the problem of expanding the arsenal of technical means of a certain purpose, i.e. a new technical solution is proposed, alternative to the already known solutions (a variant of the known solution has been created) with a new design (structure). In addition, a technical result was achieved, consisting in the implementation of the proposed technical solution of its purpose.
