MOVABLE SHUTTERING FOR MOULDING OF WALL BLOCKS Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: this relates to erection of walls from hard sand-cement mix with application of movable shuttering and immediate unshuttering. Movable shuttering includes mould, hole-forming core, fixing pintles conjugated with hole-forming core and with walls of mould, as well as extracting panel which is in contact with upper surface of moulded wall block. Mould is made with longitudinal walls and lateral walls and they are rigidly connected to each other by lateral beam. Beam together with longitudinal walls create opening which embraces wall block. Opening is covered by removable lateral wall. Mould can be made with widening towards bottom. Application of aforesaid shuttering for moulding of wall blocks cuts labour required for operation and improves thermal-insulating characteristics of wall. EFFECT: higher efficiency. 1 cl, 8 dwg
