PANEL-TYPE SHUTTERING FOR FLOORING Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: panel-type shuttering can be used for construction of monolithic flooring. Panels of shuttering are installed on telescopic posts with longitudinal beams. Longitudinal beams are made of dual girders with pivoted joint over lower internal edge. At unshuttering, this allows for turning of each girder through angle of up to 90 deg. Their working position is created due to provision of locking joint. Head-pieces of telescopic posts can be provided with supporting band with possible vertical displacement, and guide members in the form of metal strips arranged over axes of longitudinal beams for their fixed positioning. Shuttering panels can be made as multilayer. Application of aforesaid design of shuttering panels allows for reducing labour input for installing and dismantling of shuttering. Duration of concrete curing cycle up to acquiring required strength before unshuttering is also reduced. EFFECT: higher efficiency. 2 cl, 6 dwg
