BUILDING HOSTBLOCK Russian patent published in 2010 - IPC E04C1/00 

FIELD: construction.

SUBSTANCE: building hostblock includes plastic shell, shape of which makes it possible to fully fill three-dimensional space, and filler, which tightly fills the shell. Walls of the latter are arranged with ledges and slots to connect to adjacent units when erecting structures, crosswise in the form of crosses connected to each other along axis of block and arranged symmetrically to faces of bed. Plastic shell with thickness of 0.2-0.6 mm with ledges on upper bed and slots on lower bed makes it possible to form coupling of angular joints and with rigidity that preserves block alignment after introduction of filler by increasing thickness of shell from edges of side planes of shell to their centres. It is made by +250°C heating of plastic stock from preform of 50 g and blowing under pressure of 15 atmospheres (1.5 MPa) into die mould in the form of book allowing misalignment of two joining parts of die mould 0.1 mm, providing for tightness by hand tool of assembler without application of fastening material of block walls as a result of two ledges and slots for connection, accuracy of geometric dimensions of block, thickness of shell, fluidity of plastic.

EFFECT: improved efficiency of assemblers and reduced material intensity.
