BUILDING BLOCK Russian patent published in 1999 - IPC

FIELD: low building construction; applicable in erection of civil and industrial structures with high requirements for heat-sound insulation of rooms, for instance, residential buildings, cottages and other structures. SUBSTANCE: building block has concrete shell with core from heat-insulating material installed in shell before molding of building block. Concrete shell is made of two parts, preferably, rectangular in plan, with hollows facing each other. Parts are spaced from each other and from longitudinal vertical plane of block to form gap between similar upper and lower edges facing each other. Gap is filled with heat-insulating material of core and exceeds between the edges the minimum thickness at least of one of side walls of shell parts. At least one of shell parts in block cross-section is C-shaped or channel-shaped, or tray-shaped, and the other shell part is symmetrical mirror image at least over the most part of block length, of shape of its first part of shell or corresponds to one of the shapes. In mounting of structures, offered block despite its increased sizes, does not need use of load hoisting mechanism as volume of its core exceeds 60% of building block volume and shell parts are formed from concrete with light-weight filler. EFFECT: higher heat engineering characteristics, improved sound insulation and reduced specific material consumption. 10 cl, 14 dwg
