PROBLEM TO BE SOLVED: To provide a beam through-hole formation tool that is constructed to be capable of drastically reducing labors including nailing in order to fix a slide sleeve and fastener (nail and others) removing work after removing formwork.SOLUTION: A beam through-hole formation tool 1 has a slide sleeve 50, a support 10, and a connector 30. The slide sleeve 50 consists of two cylinder members that can slide to each other in an axial direction and has multiple mounting holes 53. The support 10 is fixed to a concrete formwork by inserting a nail into a fastener insertion hole 15 and supports the slide sleeve 50 at least when the concrete is installed. A mounting projection 32 is formed on the connector 30, which is detachably installed to the slide sleeve 50 when the slide sleeve 50 is slid in the axial direction toward the mounting projection and the mounting projection 32 is engaged with the mounting hole 53 from inside and is detachably installed to the support 10.SELECTED DRAWING: Figure 1
【課題】スライドスリーブの固定のための釘打ち作業や、型枠の除去後に残った固定具（釘等）の除去作業等の手間を大幅に軽減可能な構成の梁用貫通孔形成具を提供する。【解決手段】梁用貫通孔形成具１は、スライドスリーブ５０と、支持具１０と、連結具３０と、を備える。スライドスリーブ５０は、軸方向に互いにスライド可能な２つの筒部材を含んで構成されており、複数の取付孔５３が形成されている。支持具１０は、固定具挿入孔１５に釘が挿入されることでコンクリートの型枠に固定され、少なくともコンクリートの打設時にスライドスリーブ５０を支持する。連結具３０は、取付突起３２が形成されており、スライドスリーブ５０を軸方向にスライドさせて近づけることで取付突起３２が取付孔５３に内側から嵌まり込んで当該スライドスリーブ５０に着脱可能に取り付けられるとともに、支持具１０に着脱可能に取り付けられる。【選択図】図１
