STEEL REINFORCED CONCRETE BEAM FOR BEARING WALL, STEEL BEAM FOR BEARING WALL, AND CONSTRUCTING METHOD FOR BEARING WALL AND FLOOR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a steel reinforced concrete beam for a bearing wall, by which the arrangement of the vertical reinforcement of the bearing wall and the placement of concrete can easily be performed, an upper flange can be fully installed inside an RC floor board, and a floor part can be regarded as a part of the structural cross-section performance of the beam. ;SOLUTION: A pair of channel steel members 4, 4 such that a space S for arranging the reinforcement of a bearing wall is secured between their respective webs 10, 10 by pointing flanges 6, 8 outward are used as steel. A concrete block 14 is formed on one side of the web 10 of each of the pair of channel steel members 4, 4 facing the flanges 6, 8, and on the lower flange 8, and the upper flange 6 and the web 10 are exposed over the concrete block 14. Through holes 16 for placing floor reinforcement are formed through the exposed part of the web 10. In the space S between the webs 10, 10, bearing-wall reinforcement 18 is arranged, floor reinforcement 26 is passed through the through holes 16, and concrete 32 is placed to construct a bearing wall 34 and a floor board 36.;COPYRIGHT: (C)1999,JPO
