INDICATION TOOL FOR TOP END OF CAST-IN-PLACE CONCETE IN HALF-PRECAST FLOOR SLAB

摘要

PROBLEM TO BE SOLVED: To provide an indication tool for the top end of cast-in-place concrete in a half-precast floor slab, which has an effect that anyone can easily and rapidly fit the tool without jigs at anytime he wants and realizes labor saving and rationalization and improves the execution accuracy and reduces the construction period and cost and hence, which is economical and practically useful, not like conventional cases requiring bothersome works such as fastening works of bolts or adjustment of the height, for indication of the thickness of cover concrete in the placing work of cast-in- place concrete, on constructing a slab that a half-precast floor slab is constructed as a structural member. ;SOLUTION: A fitted part of upper chord reinforcements is provided at the center. An introduction groove in which a part of the fitting part 2 is opened to the outer peripheral direction and a support piece projected along the introduction groove are formed in the indication tool. And further, connection parts are appropriately formed radially from the fitting part 2 to the circular or polygonal outer peripheral part to integrally form a synthetic resin top end indication tool. A plurality of indication pieces 7 having an appropriate length are integrally and radially projected together with the indication tool 1, at the outer peripheral part.;COPYRIGHT: (C)1999,JPO
