SHEAR REINFORCEMENT STRUCTURE AND SHEAR REINFORCEMENT METHOD
PROBLEM TO BE SOLVED: To propose a shear reinforcement structure and a shear reinforcement method of an existing reinforced concrete structure in which electric power cables, gas pipes and other members have been laid, capable of effective reinforcement without removing the existing members.SOLUTION: In a shear reinforcement structure 1, having a plurality of first members 10, 10,... embedded in rows in an existing reinforced concrete structure 2 and second members 20 laid out on the surface of the reinforced concrete structure 2, a concrete cover thickness equivalent to that of the existing main reinforcements arranged in the reinforced concrete structure 2 is secured at the edge side of the first members 10, while the base end part of the first members 10 protrudes from the surface of the reinforced concrete structure 2. The second members 20 are fixed at the base end part of several of the first members 10, 10, ..., and are laid out parallel to tensile reinforcements of the reinforced concrete structure 2.
【課題】電力ケーブルやガス配管等の既設部材が配設された既存のＲＣ構造物に対して、既設部材を撤去等することなく効果的に補強をすることを可能としたせん断補強構造およびせん断補強方法を提案する。【解決手段】既設の鉄筋コンクリート構造物２に列状に埋め込まれた複数本の第一部材１０，１０，…と、鉄筋コンクリート構造物２の表面に配設された第二部材２０とを備えるせん断補強構造１であって、第一部材１０の先端側に、鉄筋コンクリート構造物２に配筋された既設の主筋と同等の被りコンクリート厚が確保されているとともに、第一部材１０の基端部が鉄筋コンクリート構造物２の表面から突出しており、第二部材２０は、複数本の第一部材１０，１０，…の基端部に固定されていて、鉄筋コンクリート構造物２の引張鉄筋と平行に配設されている。【選択図】図１
