Arrangement of bar method null of hoop muscle of the beam joint of the pillar of the reinforcement concrete structure which at least includes the pillar main reinforcement and hoop muscle

摘要

PURPOSE:To make arrangement of reinforcing bars in simple operations by placing pillar main bars in a space at the junction of H-shape steels, fixing a plurality of L-shaped hoop bars to the pillar main bars, and detaining a detent mild steel bar or bars upon inserting through a hole in the flange of each H- shape steel. CONSTITUTION:H-steel beams 12 are welded to a cruciform pillar steel 11, and through holes 12A1, 12A2 are bored in an upper and a lower flange 12A. Pillar main bars 15 are arranged in a space between the H-steel beams 12, 12 of the beam junction part 10. A plurality of L-shape hoop bars 13 are fixed to the pillar main bars 15 at a certain spacing. A detent mild steel bar 14 is threaded through holes 12A1, 12A2 in the flange 12A of each H-steel beam 12, and the tip of this detent bar 14 is sunk while detained with the detent ends 13A1, 13B1 of the L-shape hoop bar 13 fixed to the pillar main bars, and then detained. Thereby the arrangement of loop bars can be done without welding operations.
