To provide a beam reinforcing member which can secure sufficient movement of a welding torch with a minimum welding amount and enables a sound welding work.SOLUTION: A beam reinforcing member 7 provided on a through hole 5 for passing a pipe formed on a web 3 of a steel beam 1 has an insertion hole 4 having a diameter larger than that of the through hole 5 of the web 3 formed therein and is composed of a steel material having a ring shape. A plurality of recesses 9 which are cut from a center direction of the insertion hole 4 and specify a welding range are formed in an opening edge part 4A of the insertion hole 4. When being welded and fixed to the web 3, the beam reinforcing member is aligned and is brought into contact with the web 3 so that the through hole 5 and the insertion hole 4 have concentric circular shapes, and thereby an edge distance 8 is formed.SELECTED DRAWING: Figure 1
【課題】必要最小限の溶接量で溶接トーチの十分な運動が確保できて、健全な溶接作業を行うことができる梁補強部材を提供すること。【解決手段】鉄骨梁１のウェブ３に形成された配管を通すための貫通孔５に設けられる梁補強部材７であって、前記ウェブ３の前記貫通孔５より大径の挿通孔４が開設されてリング状を呈する鋼材で構成し、前記挿通孔４の開口縁部４Ａにこの挿通孔４の中心方向から切除して溶接範囲を特定する複数の凹部９を形成すると共に、前記ウェブ３に溶接して固定する際に前記貫通孔５と前記挿通孔４とが同心円状となるように位置決めして前記ウェブ３に当接させるとへりあき８が形成される。【選択図】図１
