DOUBLE REINFORCING BAR ARRANGEMENT STRUCTURE OF REINFORCED CONCRETE BASE BEAM
PROBLEM TO BE SOLVED: To enhance ductility capacity in the reinforced concrete base beam of a double reinforcing bar arrangement structure where the upper end of a pair of right and left beam reinforcement frames has, for example, a structure connected by a connecting reinforcement at a fixed pitch, and thereby brittle fracture can be avoided.SOLUTION: A connecting reinforcement frame 6A(6B) is used which includes horizontal connection reinforcements 11, and vertical connection reinforcements 12 extending in the direction intersecting the horizontal connection reinforcements 11 and welded to the horizontal connection reinforcements 11, as a connecting reinforcement for use in a double reinforcing bar arrangement structure of a reinforced concrete base beam. The connecting reinforcement frames 6A(6B) are installed, and thereby the occurrence and progress of upper surface splitting cracks after the flexural yielding of the reinforced concrete base beam can be prevented, and the ductility capacity of the base beam can be enhanced.SELECTED DRAWING: Figure 2
【課題】例えば左右一対の梁筋枠の上端が一定のピッチで連結筋によって連結された構成のダブル配筋構造の鉄筋コンクリート基礎梁における靭性能を高めて、脆性破壊を回避できるようにすること。【解決手段】鉄筋コンクリート基礎梁のダブル配筋構造に用いる連結筋として、横連結筋１１と、横連結筋１１に交差する方向に延びていると共に当該横連結筋１１に溶接されている縦連結筋１２とを備えた連結筋枠６Ａ（６Ｂ）を用いる。連結筋枠６Ａ（６Ｂ）を配置することにより、鉄筋コンクリート基礎梁の曲げ降伏後の上面割裂ひび割れの発生、進行を抑制でき、基礎梁の靭性能を高めることができる。【選択図】図２
