FORMWORK PLATE FOR FOUNDATION, LOWER FITTING, UPPER FITTING, FORMWORK MOLDING FITTING, AND WORK EXECUTION METHOD OF CONCRETE FOUNDATION

摘要

PURPOSE: To improve the workability of the concrete foundation work execution and to shorten the construction period by supporting a GRC board with a lower light fitting, which has the stabilized strength, and an upper fitting, which can be easily disconnected and recycled, so as to form the foundation formwork having a specified value. ;CONSTITUTION: Incombustible formworks 31 and 32 for foundation, which can be freely cut, made of a GRC board at 5-20mm of thickness, at 5-12kg/m² of weight, at 100kg/cm² of bending strength, which is mainly composed of the light foaming aggregate and reinforcing fiber and which is solidified with the thermosetting resin, is manufactured. Receiver members 12 are supported at both ends of the bottom plate part of a supporting member 14, and lower fittings 11, which are provided with a receiver member 13 in the upper end of a support part, are arranged with the predetermined space, and the formworks 31, 32 for foundation respectively inserted into the receiver members 12, 13, and an insertion part 22b of a side member 22 of an upper fitting 21 is inserted into a clearance between the receiver member 13 and the formwork 32 for foundation, and the upper ends of the side members 22 are connected to each other by a connecting member 23, through which a bolt 24 for fixation to the base is passed, so as to form a formwork. Concrete is placed, and after the concrete is hardened, the upper fitting 21 is removed for recycle.;COPYRIGHT: (C)1996,JPO
