The invention relates to the production of building materials used, particularly in low-rise construction, as well as in the construction of civil and industrial facilities with high demands on decorative exterior cladding, heat and sound insulation of buildings, such as houses, cottages and other buildings, in the construction industry for molding building products with a decorative outer layer.

The well-known set of building blocks for the construction of low-rise buildings by the RF patent for useful model №54060 from 29.09.2005, containing sets are made in the form of rectangular parallelepipeds three-layer ordinary blocks of three species and an angular blocks of three types. Ordinary blocks made with bearing inner layer and outer layer, made of concrete, as well as with the internal insulating layer, which are connected, at least one transverse tie passing through the inner insulating layer and the ends sealed in the front layer and the inner supporting layer. The thickness of ordinary blocks is 398 mm, and length, respectively, 198, 298 and 398 mm Blocks openings, coupling and Bay Windows are made with the tabs formed by the continuation of the front layer, and two blocks made with the tabs on the one hand, and the third with the protrusions on two opposite sides. The width of you who Tupou blocks equal to the thickness of the front layer, bump height is 50 mm, the Disadvantage of these units is the difficulty of keeping the sizes of the blocks due to their diversity and use of collapsible forms in their manufacture, the complexity in calculating the number of necessary blocks and high consumption of concrete with masonry.

Closest to the claimed unit is a multi-layer building block for RF patent for the invention №2317381 from 05.06.2006, characterized by the presence of the decorative layer thickness And base layer thickness and located between the insulating layer of polystyrene foam thickness, bonded polymer rods, made with the sharp end side in contact with the decorative layer, and with a hook at the other end, which is included in the supporting layer. The unit is made in the form of a prism, trapezoid, the base of which are the ends of the block. A smaller area of the parallel side faces of a prism is the outer side of the decorative layer block. A large area of the parallel side faces of a prism is the outer side of the base layer block. Two identical square non-parallel faces of the prism are the upper and lower base unit with the angle α of inclination to the outer side of the base layer block is not more than 1° and the ratio of the thickness of the layers A:B:C=1:2,4:2,6... But this unit is inconvenient help, especially when using the strip heater in the area of thermal efficiency of the liner to prevent cold bridge through the layer of solution as the inner (bearing) side has a large area for the application of masonry mortar and, as a consequence, less "sagging" at a greater height (a large area of the parallel side faces of a prism is the outer side of the base layer block). This, in turn, makes the solution applied to the face and bearing layers of different thickness, which requires a special skill of a bricklayer, and when multiple masters - their consistency. The increase in the thickness of the front seam between blocks to compensate for the tilt causes the extrusion of the excess solution on the front side, which leads to contamination of the textured layer and can create restrictions on the masonry rows per shift.

A known method of manufacturing a multi-layer building blocks with decorative outer surface by RF patent for the invention №2250163 from 09.27.2004, including die-casting concrete from the hopper, seal it by vibration, moving forms on the conveyor line, drying units forms in the process of moving, cooling the mold and extraction of block form. Blocky shapes perform with paired cells and mortgages dogami that pre in all cells of the form stack is atrica face layer and simultaneously fill with a mixture of two arranged in a single row across the conveyor line paired cell shape, forming a first layer of concrete by submitting portions of concrete from the hopper. Forced drying is carried out in the process of moving forms on the conveyor line at a temperature of not less than 40° for at least 12 h, then cooled form to the ambient temperature. Remove blocks by pulling from the cell together with mortgage loans dogami, stack them, putting on the sides, remove the matrix of the surface layer and send or additional drying or storage. However, this solution forces to produce blocks with a wide (high) host layer and narrow (low) a decorative layer due to the inability of popping a frozen block of metal molds. The equipment is way too expensive, occupies a large area. This method does not provide the production of blocks with color (multi-color) texture layer and blocks with different wall thickness.

Closest to the claimed method is a method of manufacturing a two-layered construction panel containing two layers, described in Russian patent for invention №2085371 from 11.11.1991, "Installation for the formation of building products with a decorative outer layer. The form is filled from the hopper decorative layer, condense it, then stack the base layer, and condense it, push the product from the mold on the movable bottom of the form, stack and is the product on the pallet and send on aging (heat treatment), and Dona forms greased. However, this solution cannot provide heat-laminated products; products with color and bump texture layer with the given, including prismatic geometry. Possible product damage when putting him on the pallet. Permanent grease bottoms takes additional time.

Declare block, as is known, consists of a decorative layer, base layer and located between the insulating layer, bonded polymer rods; the unit is made in the form of a prism, trapezoid, the base of which are the ends of the block, an area equal in non-parallel faces of the prism are the upper and lower base block.

The inventive method, as known, includes the form of the bunker decorative layer, compaction, placement of the base layer, compaction, lifting products on the movable bottom of the form, pushing it out of shape, removing the finished product from the mold and his endurance.

The objective of the invention is to improve operational properties of heat-units with a decorative outer layer.

The technical result is to create easy to use teplosberegajushhie block with a decorative outer layer, providing increased productivity when vowed the Institute building excluding damage (spoilage solution) of the decorative layer during the construction of the building, compensation of uneven subsidence of the block in the clutch, strict dosing of solution, reducing the flow of concrete in the clutch and, thus, reduce the cost of construction of the building, as well as in the creation of a production method of such a block.

The technical result is achieved in that a large area of the parallel side faces of a prism is the outer side of the decorative layer block, the smaller the area of the parallel side faces of a prism is the inner side of the base layer block, and the angle between the planes of the bases of the prism and the outer side of the front decorative layer is less than 89°. On any of the grounds in the decorative and support layers are made grooves, the axes of which are in planes parallel to the front side of the decorative layer, with the cross-sectional area of each groove more than 5 square cm, on other grounds executed corresponding to the grooves of the protrusions. On one of the sides in the decorative and support layers may be made grooves on the other of the sides can be performed corresponding to the grooves of the protrusions.

The technical result is also achieved by the fact that at the bottom of the form, the sides of which, forming the upper and lower base of the unit, is made wider at the bottom and is equipped with movable penoobrazovatelej and vystupayushchimi, stack tray and a flexible matrix, filled with plastic concrete for the top layer. Then fill the form of semi-dry concrete mix using volumetric dosing or to lower edge of window forms, compacted, insert insulating layer of polystyrene and penetrate both layers of the connecting rods. Advance penoobrazovatel base layer, fill up semi-dry concrete mix to the top of the form, close the form cover, with limited vertical clearance, condense, and then delete or move one side, forming the end of the block, and push the product from the pallet opposite the rolling Board, forming the other end of the block, and send the product with a tray and a flexible matrix for ageing. After reaching a certain concrete strength delete a flexible matrix. Bead shape, forming the upper and lower base of the unit, can be performed with a window for dispensing facial layer.

Manufacturing unit with high external side of the decorative layer, i.e. the angle between the planes of the bases of the prism and the outer side of the front decorative layer 89° or less, provides the exception of damage (spoilage solution) of the decorative layer during the construction of the building and compensation of uneven subsidence of the block in the clutch, caused by the difference of the squares of the front and the carrier layer is.

The execution of the block with grooves (recesses) on any of the grounds in the decorative and support layers, the axes of which are in planes parallel to the front (outer) side of the decorative layer, with the cross-sectional area of each recess of more than 5 cm, and with the tabs on the other of the grounds provides accurate dosing masonry mortar, reducing the flow of concrete in the clutch and, accordingly, increase productivity during the construction of the building and reducing the cost of its construction. The cross-sectional area (volume) of the protrusions is governed by the volume of solution between the decorative and load-bearing layers of the neighboring blocks in the masonry.

The invention is explained by using the drawings, in which figure 1 is a perspective view of a perspective view of a multilayer construction unit with the tabs and notches on the ends of the block, figure 2 - diagram of the masonry walls of the building from the inventive blocks, figure 3 is a top view of the masonry walls of the building blocks with tabs and slots on the grounds and in the lateral sides of the block.

Multi-layer building block represents (see figure 1) three-layer unit consisting of a decorative face layer 1, the base layer 2 and located between the insulating layer 3, made for example of expanded polystyrene foam bonded between a polymer rods 4. The unit is made in the form of a prism, trapeze the prominent base 5 which are the ends of the block, and the same square non-parallel faces of the prism are the top 6 and bottom 7 by reason of the block. A large area of the parallel side faces of a prism is the outer or front (textured) side 8 of the decorative layer 1 block, the smaller the area of the parallel side faces of a prism is the inner side 9 of the base layer 2 block. The angle between the planes of the bases of the prism and the outer side of the front decorative layer is 89° or less. The lower base 7 of the block has a protrusion 10 (crest) in the decorative layer 1 and at least one protrusion 11 (figure 1 shows 2 tabs) in the bearing layer 2, and the upper base 6 block has corresponding projections of the grooves (recesses) 12, 13. The cross-sectional area of the slots 12, 13 must be at least 5 cm, and the cross-sectional area of the ridge (ridge) may not be less than 45% of the sectional area of the groove. The grooves 12, 13 and the protrusions 10, 11 can be made round, triangular and other shapes. The grooves 12, 13 in the present invention have a dual purpose: they serve as dispensers of the solution and simultaneously the locking protrusions 10, 11 (see figure 2), providing a smooth laying of the blocks to each other, allowing you to build the walls Mason low-skilled. In addition, the grooves 12, 13 can be used for reinforcement if necessary reinforcement of the walls. Figure 3 shows a top view of the unit with the tabs and the basics on the grounds and in the lateral sides of the block. The tabs 14 and grooves 15 are also decorative 1 and host 2 layers. Production of blocks with additional grooves and ledges in the sides provides an even greater reduction of the flow of concrete in the clutch and, thus, reduce the cost of construction, since the construction of the wall stacking blocks is made by joining them to each other by connecting the end grooves - tabs without mortar.

The production method of the block is as follows.

At the bottom of the form, the sides of which, forming the upper and lower base of the unit, is made wider at the bottom and is equipped with movable tabs (penoobrazovatelej) and grooves (vystupayushchimi), stack tray and a flexible matrix, filled with plastic concrete for the front (textured) 8 layer. Bead shape, forming the upper and lower base of the unit, can be performed with a window for dispensing a decorative layer. Fill in the form of semi-dry concrete mix using volumetric dosing or to the lower edge of the window seal, insert the insulating layer of polystyrene and penetrate both layers of the connecting rods. Push the tabs (penoobrazovatel). Fill up semi-dry concrete mix to the top of the form, close the lid, with limited vertical clearance, compact vibrate to full the second lower cover or pressed). Then delete or move one side, forming the end of the block, push the product from the pallet opposite the rolling Board, forming the other end of the block, and send the product with a tray and a flexible matrix on the shutter speed to obtain the Stripping strength or before the maturity of the concrete. After reaching a certain concrete strength delete a flexible matrix.

For implementing the method uses a machine consisting of a body, molds, mechanism wypracowania block form, of a vibrator and/or the press to seal the concrete mass and the bunker. The machine can be equipped with a dosing volume. To send articles on a pallet on the shutter speed can be used specially made fixture.

In this way it is possible to make and rectangular multi-layer blocks, the difference in their production is only in shape design: bead shape, forming the upper and lower base of the unit, not made wider at the bottom and straight.

The wall of the building, formed from the inventive multi-layer building blocks, is constructed as follows (see figure 2). First on the Foundation of the lower base 7 with the projections 10, 11 on the layer of concrete is placed in a first horizontal row of blocks. Their packing is made by joining them to each other side ends and the bond between the concrete or by with the unity of the grooves of the protrusions in the manufacture of blocks with grooves and ledges in the sides of the block. Each subsequent row is formed by stacking protrusions 10, 11 lower bases 7 blocks filled with concrete grooves 12, 13 (deepening) of the upper base blocks of the previous row. When this leakage of concrete is mainly in the direction of the base layer, under bias, which eliminates the damage (the spoilage solution) front textured layer 8. In the grooves 12, 13 of the upper base 6 blocks can be stacked valves (not shown). The corners of the building can be tiled with corner blocks (not shown), representing two of the decorative layer unit, collected an l-shape, the difference in length which corresponds to half the length of an ordinary block. Formed corner block cavity can be filled with any thermal efficiency of a material, such as penopolistirolbeton.

Thus, this design of multilayer unit manufactured using the proposed method provides increased productivity when constructing a building, excluding damage (spoilage solution) of the decorative layer during the construction of the building, compensation of uneven subsidence of the block in the clutch, strict dosing of solution, reducing the flow of concrete in the clutch and, thus, reduce the cost of construction of the building.
