CONSTRUCTION BLOCK Russian patent published in 2014 - IPC E04C1/00 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular, to construction elements in the form of finished construction blocks for erection of bearing and barrier structures of buildings and facilities. A construction block has the shape of a rectangular parallelepiped and comprises three identical and parallel panels connected to each other. Each panel comprises two flat parts and a layer of filler between them. All panels have identical through holes of round shape, where connection parts of cylindrical shape are inserted. The middle panel is displaced relative to side panels so that in the middle of the construction block on its larger side face there is a long ledge, on its opposite side face there is a long groove, on the smallest side face there is a short ledge, and on the opposite side face there is a short groove. On one of largest side faces of the middle panel there are ledges in the form of a square prism, and on its opposite face there are grooves, which fully match the ledges by shape, size and location. Between them the panels are fixed with the help of glue or with the help of fastening elements. During assembly of a construction structure, ledges of adjacent construction blocks are matched with appropriate grooves, and ledges of adjacent middle panels are coupled with appropriate grooves, also at the angle of 90 degrees in the horizontal plane. By means of the specified matching and coupling the location of each construction block is self-aligned and fixed in all orthogonal planes, accuracy of assembly and stability of the construction structure to external impact is provided. The multi-layer structure of the construction block provides for its high strength under low own weight, filler layers of all panels create heat and sound insulation.

EFFECT: low weight, convenience of manipulations and simplicity of coupling of adjacent construction blocks make assembly of construction structures from them possible manually and within quite a short period of time.
