KAMIYAMA TAKESHI / TSUKADA MASAKAZU / SAITO HIROYUKI

To provide a beam end part reinforcing structure which can reinforce an existing beam when removing a shaft column for supporting an end part of the existing beam of an existing building in a longitudinal direction.SOLUTION: In order to solve a problem, a beam end part reinforcing structure 1 comprises: a reinforced existing beam 3 being an object of reinforcement out of existing beams 2 which are arranged in an existing building; and a beam-shaped reinforcing member 4 for reinforcing the reinforced existing beam 3. The reinforced existing beam 3 becomes an object of reinforcement due to the removal of a removed shaft column which has supported an end part of the reinforced existing beam 3 in a longitudinal direction, the reinforced existing beam 3 is located between the two existing beams 2 which are parallel with the reinforced existing beam 3, and the beam-shaped reinforcing member 4 is bridged between the two existing beams 2 sandwiching the reinforced existing beam 3 so as to be orthogonal to the reinforced existing beam 3 at a lower part of the reinforced existing beam 3, and supports an end part of the reinforced existing beam 3 in a longitudinal direction from below.SELECTED DRAWING: Figure 1

【課題】既存建築物の既存梁の長手方向端部を支持する軸柱を撤去した場合に、当該既存梁を補強することができる梁端部補強構造を提供すること。【解決手段】上記課題を解決するために、本発明に係る梁端部補強構造１は、既存建築物に設けられている既存梁２のうち補強の対象となる被補強既存梁３と、被補強既存梁３を補強するための梁状補強部材４と、を備え、被補強既存梁３は、被補強既存梁３の長手方向端部を支持していた被撤去軸柱を撤去したことによって補強の対象となったものであり、被補強既存梁３は、被補強既存梁３と平行な２つの既存梁２の間に位置しており、梁状補強部材４は、被補強既存梁３の下方で被補強既存梁３に直交するように被補強既存梁３を挟む２つの既存梁２の間に架け渡されて、被補強既存梁３の長手方向端部を下方から支持することを特徴とする。【選択図】図１
