SHUTTERING Russian patent published in 1997 - IPC

FIELD: construction engineering. SUBSTANCE: this shuttering can be used for manufacture of structures from cast-in-place concrete and reinforced concrete. Side walls of contour ribs of shuttering are made with teeth. Positioning pitch of teeth on side walls and their width are equal to half thickness of single plate which forms deck of panel. Minimal number of teeth per single plate is larger than number of deck plates. Oval holes in contour ribs are located perpendicularly to deck surface and their width is equal to diameter of fastening bolt. Length of oval hole is less or equal to 30 heights of side wall of contour rib and larger than diameter of fastening bolt by thickness of single plate with coefficient equal to number of deck plates reduced by one. Height of teeth can be equal to 1-2 mm. EFFECT: high efficiency. 1 cl, 9 dwg
