1. The invention relates to the construction and can be used in the manufacture of building envelopes in terms of a wide range of seasonal temperatures.

Known similar "Block wall construction" EN 2131501 C1 CL E04C 1/40. In this block, the concrete shell is connected with the insulating core only due to the adhesion of the concrete, which is not sufficient.

Known analogues "Concrete block" EN 2208102 C1 CL E04C1/40, "Building block" EN 2208101 C1 CL E04C1/40, "Concrete building block" EN 2317381 C1 CL E04C1/40, "multi-layer building block" EN 2317381 C1 CL E04C1/40, "heat-Insulating building block" RU, 33 589 U1, E04C1/00. When creating these materials, an attempt was made to create a multi-layer building block, connecting bearing and insulating layers using fiberglass, plastic, and metal rods of different configurations. As shown, this connection cannot withstand the serious load. Joints in this building structure is not insulated in any way and are "cold bridges".

The prototype is a "heat-Insulating building block", EN, 33589 U1, E04C1/00, 27.10.2003, PP-22, 36 formula, p.5-6 description of, 4-12, /1/, which describes a multilayer insulating building block, including external and internal the unit layers, made on the basis of different binding solutions, between which the insulating Styrofoam plate, for example, polystyrene foam, which is made of the through-hole for the formation of links. The insulating plate is shifted in the vertical and horizontal plane relative to the faces of the outer and inner layers of the block by a value not less than the thickness of the mortar joint. The disadvantage of this insulating block is insufficient bonding strength of the layers using the specified elements of communication, because the holes for their formation are in the same plane. Despite the presence of additional insulation boards are "cold bridges"because of the holes in the two insulating plates are located on the same axis. In the prototype is specified (page 6 of the description)that is manufactured building block according to standard technology in the forms, it does not specify how to keep it from surfacing lighter layers of polystyrene foam when pouring a load-bearing layers and how is the uniformity of the thickness of the bearing layer, which is of paramount importance when creating the material connection (p formula). Therefore, as a prototype for the method of manufacture and apparatus for manufacturing the fuser selected closer on a technical level, the "Fuser", EN, 2157875 C2, 04C 1/00, B28B 7/22. (PP,7 formula), the disadvantage of this method and device is the impossibility of fixing the insulating layer outside faces of the bearing layer. The purpose of this invention was the creation of a set of unified thermally protected products for construction, combining all the advantages of existing building blocks, but devoid of the disadvantages of these products, as well as method and device for its manufacture.

1.1 Technical result achieved when using the invention:

1.1.1 Increase the strength of the connection layers in multilayer fuser.

1.1.2 Improving thermal properties of multilayer fuser.

1.1.3 Increase heat and windproof properties of the building envelope as a whole.

1.1.4 improving the quality of the installation due to the precision of the Assembly.

1.1.5 reducing the number of masonry material.

1.1.6 the Opportunity to fulfill facing in parallel with the masonry works without installation of scaffolding (for multi-storey building).

1.1.7 a Significant reduction in construction time.

1.2. The challenge is in getting the kit termozakalennyh uniform products of house-building systems for low-rise and precast-monolithic construction, having the properties that provide the claimed technical result and having h is superexistence differences from the prototype and its analogues.

This technical result is the following differences fuser: multilayer fuser for construction, containing a three-dimensional rigid - item matrix, and the block consists of three load-bearing concrete layers and two located between insulating layers of foam, such as polystyrene, with holes for the connection of three concrete layers in a single monolithic structure through education monolithic lintels during pouring, and insulating layers are shifted relative to the bearing layer vertically and horizontally to obtain the material connection blocks that completely isolates bearing layers from each other insulating layers on the edges of the block in the zone of contact with the glue mixture, characterized in that the concrete lintel in one insulating layer is shifted relative to the jumper in the other insulating layer on the maximum size and have a size of section is necessary to ensure structural strength, and when the partition connection adhesive layer, having the highest thermal conductivity, the installation process is broken into 5 segments, respectively, the number of layers.

1.2.1 multi-layer fuser consists of five layers: three bearing construction made of foamed or expanded clay, concrete representing samojedny monolithic spatial element (matrix) (1), two layers of EPS (2), and are made of foam (such as Styrofoam or other materials with similar properties) (Fig.1-4).

1.2.2 In insulating layers are holes, "mirror" shifted relative to each other in each layer (Figure 2). Holes should be at least three in each layer for the formation of solid bridges (3) (3), provides the necessary bonding strength of the layers during pouring. The shape of the section of the jumpers may be different. The layers of insulation are shifted vertically and horizontally relative to the bearing layer to a depth sufficient for the formation of the material connection of thermal blocks. Thus there are formed two rows of tongue and groove vertical and horizontal elements, greatly improving thermal insulation properties of masonry, as well as completely eliminating its insufflation. Partition units connection greatly improves the quality of installation. The edges of the block in the zone of contact with the glue mixture, construction layers are completely isolated from each other by insulating layers. The application of the adhesive layer by using devices of mechanization allows you to minimize costs on the adhesive mixture and significantly improve the quality of masonry, productivity and reduce heat loss by suture joints. When partition blocks connect the research Institute of the adhesive layer, with the greatest conductivity, in the process of installation is broken into 5 segments (number of layers), thereby increasing the overall thermal resistance of the building envelope.

1.2.3. To facilitate mounting of the angular designs created corner elements multilayer fuser (5-6).

When using multilayer fuser for the manufacture of walling in frame-monolithic high-rise construction, revealed main major advantage is no need for the installation of scaffolding that provides significant economic benefits. In scaffolding is not necessary, as high-quality insulation already made in the process of masonry work, and facing multi-storey buildings can be conducted in parallel with the stacking blocks inside buildings. Insulating layers of expanded polystyrene inside the concrete blocks do not burn, therefore the proposed multilayer fuser has superior fire properties.

There is a significant savings in time, labor, and, consequently, a sharp increase in economic indicators of construction, while improving the quality of work.

2.1 the Method of manufacturing a multilayer fuser differs from the prototype so that there is a technical result, it is impossible for prototype - division form for making insulating layers allows to fill the outer concrete layer simultaneously with the internal (claydite-concrete) concrete mix with different (visual and mechanical) properties, while the layers are firmly connected to each other inside jumper (3) in the process of making. In similar Concrete building block" EN 2317381 C1 CLE04C1/40, "multi-layer building block" EN 2317381 C1 CLE04C1/40 attempted connection concrete layers with different visual and structural qualities through the layer of peopl the hundred with a metal, plastic or fiberglass reinforced plastic rods by continuous horizontal casting of bearing construction layers and horizontal stacking insulating layer between them, but with this method the strength of the connection construction of the layers is low and it is impossible to maintain the predefined thickness of the concrete layer.

SUBSTANCE: invention relates to flaky items used in construction for heat insulation of buildings and premises in it. The heat and sound insulation unit comprises filler webs laid one onto another, every of which comprises a corrugated sheet with corrugations of zigzag shape and a flat sheet connected to it. In each filler web, at least at one longitudinal side of the filler web, the flat sheet is arranged with a transverse size below the corrugated sheet by value of at least half of a pitch of a zigzag-shaped corrugation, thus producing a compensator from corrugations protruding beyond the flat sheet, capable of being compressed in transverse direction for gapless laying of the filler web into a building structure. A serrated line of corrugated sheet bend matches the edge of the flat sheet of the web. In the first version of block laying into a building structure the block is pressed with its longitudinal side with a compensator to the element of the building structure, and in this condition it is installed into the filled space of the building structure. The block compensator due to action of springing forces fills a gap produced between the block and the element of the building structure. In the second version, in case of layer-by-layer installation of block filler webs into a building structure, block filler webs that are adjacent along the height of the building structure are laid with a rotation relative to each other by 180, and thus the compensator of the below block filler web is covered with a flat sheet of the filler web sheet. In the third version, in case of layer-by-layer installation of block filler webs into a building structure with equal longitudinal and transverse dimensions, block filler webs that are adjacent along the height of the building structure are laid with a rotation relative to each other by 90, and thus gapless laying of the block is provided at all sides of the building structure.

EFFECT: invention provides for higher heat and sound insulation properties of blocks due to elimination of gaps between elements of building structures and fillers.
