MODULAR WALL STRUCTURE Russian patent published in 1997 - IPC

FIELD: civil engineering. SUBSTANCE: modular wall structure has non-removable box- shaped shutter of foamed plastic of polystyrole type and has opposite parallel side and end walls, installed on ends of lateral walls and a pair of installation vertical grooves originated on inner surfaces of lateral walls to form the cavity for being filled with concrete. Interval between lateral walls is kept by crosswise connectors installed into the opposite T-shaped grooves originated on the lateral walls. Crosswise connector has two tails. Perforated lintel is placed between them perpendicular. Holder of vertical reinforcement bar is placed in center of lintel. Holder of horizontal reinforcement bars is formed by two inclined edges of the upper lintel part, outer surface of the holder of vertical reinforcement bar and ledges placed on upper edges of the lintel at equal distance from the holder of vertical reinforcement bar and tails. Units of interconnection for wall modules in vertical direction are made at upper and lower surfaces of the lateral and end walls. Vertical recesses are there on outer and inner surfaces of the lateral walls of modules of cylindrical shape. Lateral walls are bent about the vertical axis that is parallel to vertical recesses. Corner module of the wall has two shutters. End surface of the second shutter is joined to outer surface of the lateral wall. An aperture to join cavities of two shutters is originated in the lateral wall of the first shutter. EFFECT: improved design. 3 cl, 7 dwg
