THIN-WALLED BUILDING BLOCK Russian patent published in 1995 - IPC

FIELD: civil engineering. SUBSTANCE: arch structure block has longitudinal thin- walled lateral members with flangings fixed on a sheet and thin-walled cross members of angle-shaped cross-section. The lateral longitudinal thin-walled members have channel-like cross-section and flanges directed outside. The sheet has flanged edges overlapping the upper flanges of the channels. The longitudinal thin-walled lateral member flanges are in perpendicular to those of the channels in a way that each pair of the flanges located on the lower and upper flanges of the channels are of different height, respectively, and each sheet flange is adjacent to the corresponding flange of the lateral thin-walled member, unidirectional to it and of the same height. The block is also provided with an additional sheet covering the lower flanges of the lateral longitudinal thin-walled member and a heat retention material lagging placed between the sheets. EFFECT: effective heat insulation, simplified and accelerated installation process. 4 cl, 10 dwg
