REINFORCING MATERIALS AROUND THROUGH-HOLE OF BEAM SECTION OF REINFORCEMENT OR STEEL FRAME/REINFORCED CONCRETE STRUCTURE

摘要

PURPOSE:To promote aseismicity by bending both ends of a horizontal reinforcing steel with a certain inclination, and forming main reinforcing bars having the same lengths of right and left inclined parts and auxiliary bars connecting the main reinforcing bars to each other into two layers in the shape of an approximate octagon. CONSTITUTION:There is a space section 3 having a hole of a beam in the central part thereof, and reinforcing materials are constituted of main reinforcing bars 1 consisting of two bars each in up and down arranged in parallel across the space section 3 and bar-shaped auxiliary bars 2 welded to the main reinforcing bars 1 with them diagonally crossed. After that, the first layer is constituted of the main reinforcing bars 1 of the upper part C1 of the reinforcing materials and the auxiliary bars 2 of the lower part C2 of them, and the second layer is constituted of the auxiliary bars 2 of the upper part C1 and the main reinforcing bars 1 of the lower part C2. All the intersecting points of the main reinforcing bars 1 with the auxiliary bars 2 are connected by means of welding. According to the constitution, strength and aseismicity can be promoted by placing the auxiliary bars diagonally crossed with horizontal parts of the main reinforcing bars on part correspondent in the horizontal direction of the hole.
