The technical field to which the invention relates

The present invention relates to the field of building materials and construction elements, namely to the design of a set of concrete building stones.

The level of technology

Known symmetrical stone wall with ordinary through annular cavities having at the ends of two longitudinal troughs to create the mortar dowels for masonry (see GOST 6133-99, Fig. B. 9). When the through-voids is overrun masonry mortar and weighting of the wall. To avoid this the above GOST possible to perform non-through cracks. While the stone itself becomes harder, which also leads to an increase in the weight of the entire wall, i.e. to the increase of the construction cost. In addition, the greatest challenge is posed by vertical seams that are a lot of masonry mortar with strict requirements for its plasticity.

In GOST 6133-99 also the above construction of partition blocks (see Fig. B. 7, B. 8) or with smooth ends, or with depressions for the formation of mortar dowels. Septal stones (PC) together with ordinary stones (RK) form a system that allows you to build not only the load-bearing or self-bearing walls of buildings, and partitions within them.

In addition to the described disadvantages of the stones (B. 9) it's hard prick, so for normal operation Kamenica� require additional finishing or corner stones. All this increases the range, complicates logistics and requires additional space for storage of products and avoidance of re-grading.

In addition, with the use of these stones are related to the problem of providing the required parameters on the sound insulation of walls, since the sound insulation depends on the quality of vertical seams, and in the case of pustoshovki this clutch can negate all the efforts of the builders and constructors.

There is a solution which avoids these drawbacks (see RF patent for useful model No. 101401). The ledge on one end wall of an ordinary stone and a corresponding groove on the other allow you to create bearstone the connection stones, and additional longitudinal aperture provides reliable sound insulation wall even when the wall chasing with two sides.

This solution has the following disadvantages.

In case of need in additional element, the stones must be split, and these stones are hard to crack. They can only be cut using special equipment that the construction is extremely difficult to ensure that every workplace. When trying to reduce weight and dimensions of the stone (its thickness) having problems with sound insulation. Besides, such stones are not in line with modern wall stones having grooves and protrusions on the ends than the size�in the grooves and protrusions above ordinary wall stones (see the website section bulkhead stones").

To eliminate these disadvantages of the proposed solution of ordinary stone wall with protrusions on one end wall of stone and with the corresponding grooves on the other (see RF patent for useful model No. 100787), and the grooves and ledges of these rocks correspond to the protrusions and grooves of partition blocks, which makes possible their bearstone connection in different combinations. In addition, this stone has high insulating characteristics due to the corrugated rough texture of the internal surfaces with the correct alternation of longitudinal protrusions and / or depressions (see GOST 6133-99, p. 3), and the tops of these projections and depressions on the adjacent inner surfaces are shifted relative to each other.

It is obvious that the increase of the coefficient of sound insulation (R3we are more than comfortable accommodation; or when consistently given R3allows to reduce the width of the stone, i.e. to reduce the construction costs.

However, this stone also has flaws that do not correspond to the modern level of development of the construction industry.

The presence of cracks of complex shapes is certainly a progressive step, however, these RK cavity cracks and roughness of their internal surfaces are not along the entire length of the stone. As for the ends of the stones, at their connection the way�is solid solid jumper, through which the sound passes, bypassing complex annular space.

The present invention is to create a design of a set of concrete stones, which will be addressed the above shortcomings, as well as the task of further increasing the sound insulation coefficient (R3).

Disclosure of the invention

The above problem is solved by creating a set of concrete stones, which consists of raw stone (RK) with Central cavities separated by bridges and exposed to the end surfaces of the stone, and more than two times narrower bulkhead stone (PC) whose end faces are identical protrusions and corresponding grooves, and the claimed set of concrete stones differs in that all internal surfaces of the stones, including the Central cavity of the Republic of Kazakhstan, made with corrugations or rough edges, and protrusions and depressions of the curved corrugation and the neighbouring cracks and cavities are shifted relative to each other, and with all the cracks of the Republic of Kazakhstan and the PC except the Central cavities in the ROK are blind.

In an embodiment of the invention jumpers in the Republic of Kazakhstan between the Central slits can have a height less than the height of the stones.

In an embodiment of the invention in the laying of the gem of the Central slit of the Republic of Kazakhstan and the space between two parallel PCs, connected�bubbled with RK, can be filled with sound absorbing materials.

The technical result is to improve the sound insulation properties of the walls without increasing construction costs, as well as providing convenience and ease of masonry works.

The implementation of the invention

The proposed design of ordinary stone, shown in Fig. 1, in which:

1 - ordinary stone (ROK);

2 is an end surface of the RK with the projections 3 and grooves 4, and RK of length L and width consists essentially of two stones 5 width b with internal non-through slots 6 having a corrugated surface. Mentioned the stones 5 are connected to each other by crosspieces 7, which have a height less than the height H, the value of S.

Thus, an ordinary stone (RK) 1 is an essentially two bodies in the form of a rectangular parallelepiped (5 stones), each of which has one end side vertically oriented protrusion 3 in terms of form, close to the trapezium, and on the other end side vertically oriented groove 4 of a shape corresponding to the shape of the protrusion 3, and the two bodies are placed parallel to each other at a certain distance from each other (Central cavity) and connected by at least two crosspieces 7, arranged at a distance from the end faces of the 5 stones. Thus, RK 1 is open at the ends and has �ENISA least one of through the Central cavity between the ridges 7. In addition, the stones 5 are vertically oriented internal non-through slit 6, which can be opened with one of the horizontal surfaces of the stone 5, but do not reach the opposite horizontal side of the stone 5.

In addition, a set of stones also includes a separate partition stones (PC) 8 having a width more than two times smaller than the width of ordinary stones (RK) 1, and also representing the body in the form of a rectangular parallelepiped having one end side vertically oriented protrusion 3, and the other end side, a vertically oriented groove 4, which by their form correspond to the protrusion 3 and the groove 4 of the 5 stones of ordinary stone 1. It provided the possibility of joining the septal stone (PC) 8 with any of the stones 5 RK 1.

PC 8 has a length L and may have an internal cavity, analogous to the internal cracks 6 RK 1, the inner surface of which is serrated or have a roughness (see Fig. 2). Fig. 2 shows the clutch (bottom view) in which RK 1 is connected to a PC 8, in this case, since RK 1 stones 5 are only connected by crosspieces 7, between them are formed through the cavity, so that the end of massive fragments of disjointed stones. The alternation in the laying of the stones 1 and 8 allows for a much easier installation, because the 8 stones lighter, with namepros to work but RK 1 it ensures the correct orientation of the 8 stones in the wall due to the " groove and raised connections. Internal through cavity 9 RK 1, also formed of corrugated or rough walls of stone and having a width of 5 and provides additional insulation. Also between stones 8 by their coupling with RK 1 automatically creates a cavity 10. The presence of roughness on all internal surfaces of the Republic of Kazakhstan 1 provides increased reflection and scattering of the sound waves and thus throughout the entire wall, the principle of alternation of the environment with high density environment with low density. If necessary additional elements stones 8 easily shoot up (like the bricks) hand tools, without the need of special equipment.

Fig. 3 shows a variant in which the clutch is coming to the wall 11, while the distance L1<L is provided with split stones 8, which on one side are joined with RK 1, and the other through the mortar seam 12 are joined with the wall 11.

Fig. 4 shows the performance of angle (top view), when RK 1 ensure "alignment" split to the right size stones 8A, 8b and 8c. Chipped gems are joined mortar joints, the strength of the angle may be increased at the expense of a corner reinforcing bars 13, which are laid in the horizontal joints.

Proper design for�allows to reduce the number of required additional elements, but in case of need, the process of splitting stones is simple and allows you to keep the cavities 9 and 10 and also in a difficult corner elements.

Fig. 4 shows the performance of the end item (e.g., an aperture), when the edge portion of the cavity 9 of length l1is filled with a block of wood 14 width l3which is planted on the glue thickness l4or mounting adhesive foam. Obviously, instead of a piece of wood can be another element (plastic cap, foam liner, etc.).

Fig. 5 shows the case of the niches in the wall to accommodate, for example, the electrical panel or the necessary shelves or other technological elements. Fig. 5 masonry also shown as a top view, when the bed of stones 1 and 8 create a surface for the application of the solution. So the solution is not to fall into the voids, mortar is usually used "tapes of a desired width and thickness.

Fig. 6 shows a fragment of masonry, when interroom partition thickness To fit in with interior partition, made of PC 8.

To further increase the sound insulation is possible the space filling of the cavities 9 and 10 absorbing materials such as mineral wool sheets, or sheets of Styrofoam, or monolithic foam of low density. In these cases, in addition to high zvukopisi�arousih properties of RK decreases and its thermal conductivity, allowing you to use this RK in effective walling, moreover, that the proposed stone has virtually no cold bridges.

Jumper 7 do not bear the load and are only used to connect two parts of the Republic of Kazakhstan 1, while their height is equal to hp=H-c and thus in the mounting position of the stone at the bottom of the jumper 7 is formed a free space that can be used for the organization of attachment of stones over the openings.

Fig. 7 shows RK 1 in this position, between two walls of an aperture opened the metal frame 15, which ensures a stable position of the stones. To increase strength nadbramny jumper space of the cavity 9 is filled with concrete.

Fig. 8 shows how you can use stones for 1 multi-layered outside wall construction, in which the cavity space 9 RK 1 filled with concrete 16. Next, a wall of small RK insulated plate heater 18, which is attached to RK 1 stainless (e.g., plastic) dowel 17 umbrella type, pressing the heater 18 to the Republic of Kazakhstan 1. Further, the insulation on the grid 19 plastered with a thin layer of plaster 20. Dowel 17, passing through two walls of stone, provides reliable fastening of insulation to the wall. By increasing the length of the dowels 17 and he falls into a layer of insulation 16. In any case, offer�, the types of rocks 1 and 8 provide when sharing the required amplification dug and can be used for walling tall buildings.

The use of a layer of insulation 16 to reduce the thickness of external insulation 18, i.e. to reduce overall costs for installation of the wall while improving its insulating qualities.

Void stone 1 is serrated, with depressions and protrusions for better audio dispersion advisable to perform a curve.

If the distance between the peaks of the protrusions is equal to T, then on the adjacent surfaces, it is advisable either to shift the corrugations by ΔT (see Fig. 9), either to produce corrugations with another step T1≠T.

Fig. 10 shows an embodiment in which the length of PC 8 twice RK 1. Since the stone is 8 more than twice easier RK 1, by increasing the length of the PC reduces the complexity of the masonry in accordance with overall size, enabling easy execution of masonry. In any case, it is obvious that the length of the stones 1 and 8 must be multiples of each other.

Thus, the presented set of stones helps to improve acoustical characteristics of the walls without increasing construction costs, and provide the convenience and ease of masonry works.
