PRECAST WALL SLAB AND CONSTRUCTING METHOD OF BUILDING USING THE WALL SLAB

摘要

PROBLEM TO BE SOLVED: To facilitate connection operation with another structural material, and to rationalize operation by forming a notch section to the peripheral section of a wall slab body and extending an embedded bar constituting a lap joint with a joint bar projected from another structural material into the notch section from the inside of the wall slab body. ;SOLUTION: A column member 20 and a wall slab 10 are joined in such a manner that a joint bar 21 is projected from the column member 20 as another structural material, the precast wall slab 10 is built, the joint bar 21 forms a lap joint with an embedded bar 12 in a notch section 11b, an opening 11c is closed by a frame plate 22 and a concrete placing space S1 is filled with concrete. Since the embedded bar 12 is disposed into the notch section 11b, the reinforcing bar for connection is arranged beforehand in the space S1, thus facilitating connection operation. When the wall slab 10 is joined with a coin member 20, the opening of the notch section 11b can be partitioned only by closing the opening by the frame plate 22, the leakage prevention, etc., of concrete may be conducted only in the periphery of the notch section 11b, and operation can be rationalized.;COPYRIGHT: (C)1997,JPO
