The invention relates to the field of construction and can be used in the construction of various buildings of brick and other masonry materials.
Known lightweight masonry, consisting of inner and outer layers, the United transverse vertical and horizontal diaphragms with slab insulation installed between the diaphragm layers close to the inner wall, observing the sealed plates in the joints to each other and to defraites. Stone designs and their construction. - M.: stroiizdat, 1989, Fig.11.17, page 92).
Shows similar to the technical essence is the closest to the claimed invention and is taken as a prototype.
The disadvantage of the prototype is that during the operation of the building in the slab insulation is shrinking, leading to air circulation between the layers of masonry; thereby violated thermotechnical properties of the fence.
The technical result - the increase of the resistance of the wall heat transfer, provision of thermotechnical calculation.
This technical result is achieved by the fact that the slab insulation has a U-shaped profile, consisting of two layers connected by a bridge. The total thickness of the layers of insulation and the width of the air gap meet in the prototype.
The invention is illustrated by drawings, which depict:
in Fig.1 - section lightweight masonry;
in Fig.2 is a view of a laying along section 1-1.
Lightweight masonry includes inner 1 and outer 2 layers, the United transverse vertical diaphragms 3, plate heater 4. As slab insulation can be applied foam. Slab insulation 4 has a P-obraznye masonry and connected by a bridge 5. Between the layers of insulation formed air gap 6. When erecting masonry on the jumper 5 through a solution of stacked bricks horizontal diaphragm 7. When uploading masonry load from the horizontal diaphragm is transmitted to the slab insulation 4. Since the rigidity of the jumper 5 is much less than the stiffness of the layers of plate heater 4, the slab insulation 4 starts to operate as a P-frame, with the load attached to the transom frame. Due to the deflection of the layers of insulation, they are constantly pressed against the inner surfaces of the layers 1 and 2 of masonry, which prevents air circulation from the outside cold and masonry surfaces according to the law of the convective motion.
Lightweight masonry, including the inner and outer layers, the transverse vertical and horizontal diaphragm slab insulation and air gap, characterized in that the slab insulation has a U-shaped profile, consisting of two layers closely adjacent to the inner surfaces of the outer and inner layers of masonry, connected by a bridge, adjacent to the horizontal aperture.
FIELD: construction, particularly outer load-bearing walling structures of buildings and building structures.
SUBSTANCE: building wall formed of small building members comprises outer and inner layers and metal inserts. The wall additionally has vertical stiffening diaphragm plates. Metal inserts have Z-shaped cross-sections and are periodically spaced along wall plane. Flanges of the inserts are arranged in inner and outer wall layers correspondingly so that vertical middle face works in shear and folded flanges located on masonry plate work in crush. Metal inserts unite inner and outer wall layers along stiffening diaphragm plates in single structure.
EFFECT: increased wall maintainability and reliability of cooperation between masonry members.

FIELD: building unit production.
SUBSTANCE: building system comprises building units with fixing members made as extensions and depressions. Building units are formed as sectors arranged in horizontal plane and forming a circle. The sectors may be added in length in vertical direction. Centers of fixing members are located on concentric circle and spaced equal distances one from another. Some sectors facing circle centre form cylindrical cavity for fastening rod receiving during system lengthening.
EFFECT: simplified building unit transportation, reduced material consumption, increased convenience of system installation in confined area.

FIELD: building, particularly composite and cast-in-place building erection, for outer load-bearing structure heat insulation due to elimination of cold penetration through joints of reinforced concrete floor structure with load-bearing walls and/or columns.
SUBSTANCE: envelope wall structure includes end surfaces of load-bearing members arranged between cast-in-place reinforced concrete floor panels and blocks fastened one to another with concrete and arranged between floor panels. The structure also has heat insulation. The blocks project outwards with respect to end surfaces of load-bearing members for a distance of not less than 1/6 of block width. The heat insulation is arranged in depressions. Depression walls are defined in vertical direction by end projected surfaces of blocks and load-bearing members and in horizontal direction by lower and upper projected surfaces of blocks and end surfaces of reinforced concrete floor panels.
EFFECT: simplified structure and reduced costs of wall envelope structure, increased thermal properties and elimination of cold joints between floor structure and load-bearing walls.
