SLIT MATERIAL FOR EARTHQUAKE RESISTANCE AND JOINT STRUCTURE OF CONCRETE WALL

摘要

PROBLEM TO BE SOLVED: To provide a slit material for earthquake resistance, which prevents the flying of a core material in the case of the placing of concrete and can be installed simply when the slit material is mounted on forms and can from a joint to a concrete surface when the forms are removed and has the excellent shape of the joint.;SOLUTION: The slit material for earthquake resistance is composed of the core material (3) consisting of a foamed synthetic resin, a supporting member (6) arranged so as to form the joint (10) in the external surface of a wall (1) and a fixing member (4), in which an external end section is pinched by the forms (7), a pair of wedge-shaped sectional rib sections (9), (9) are formed oppositely within a range narrower than the width S of the drum section (6c) of an internal end section (6a) at the external end section (6b) of the supporting member (6) forming the joint (10) of the wall 1 made of concrete, an approximately trapezoidal recess (6d) is formed between these rib sections (9), (9), and the projecting angles α of the rib sections (9) are formed within a range of 3-45°.;COPYRIGHT: (C)2001,JPO
