METHOD FOR REINFORCING OPENING OF BEAM AND BEAM STRUCTURE
To provide a method for reinforcing the opening of a beam and a beam structure that can efficiently reinforce a through-hole.SOLUTION: In a beam structure 10, a through-hole 25 is provided in a direction orthogonal to the axis of a beam 20, and a slab 30 is arranged above the beam 20. Below the through-hole 25, a reinforcing plate 41 is welded to the lower surface of a lower flange 22 of the beam 20 as a reinforcing member for reinforcing the strength lowered by the through-hole 25. A reinforcing bar 42 embedded in the slab 30 is arranged above the through-hole 25 as a reinforcing member for reinforcing the strength lowered by the through-hole 25.SELECTED DRAWING: Figure 1
【課題】効率的に貫通孔を補強することができる梁の開口補強方法及び梁の構造を提供する。【解決手段】梁構造10は、梁20の軸に対して直交する方向に貫通孔25が設けられ、梁20の上方にスラブ30が配置される。貫通孔25の下方に、貫通孔25により低下した耐力を補強する補強部材として、梁20の下フランジ22の下面に補強板41を溶接する。更に、貫通孔25の上方に、貫通孔25により低下した耐力を補強する補強部材として、スラブ30に埋設される補強筋42を配置する。【選択図】図1
