CONNECTION TOOL
PROBLEM TO BE SOLVED: To provide a round bar-shaped connection tool which can absorb impact without generating concentration of stress, and takes convenience during construction into consideration.SOLUTION: A connection tool 10 embeds a plurality of members 31 and 41 so as to penetrate through prepared holes 33 and 43 provided on the members 31 and 41 in order to integrate the members 31 and 41, but has side holes 13 and 14 penetrating a drift pin 25 inserted into the members 31 and 41 provided on a side peripheral surface of the connection tool 10. The connection tool 10 is provided with an oval hole 17 extending in an axial line direction so as to cause elastic-plastic deformation, but the oval hole 17 is arranged between the side hole 13 positioned inside one member 31 and the side hole 14 positioned inside the other member 41. With the configuration, when a tensile load acts on the connection tool 10, in a region positioned outside the oval hole 17, stress is substantially equally dispersed, and impact can be absorbed without causing concentration of stress. The connection tool 10 has one bar shape, is handled similarly to a conventional tenon pipe, and shows no deterioration in convenience during construction.SELECTED DRAWING: Figure 1
【課題】応力集中を生じることなく衝撃を吸収可能で、しかも施工時の利便性にも配慮された丸棒状の連結具を提供する。【解決手段】連結具１０は、複数の部材３１、４１を一体化するため、部材３１、４１に設けた下穴３３、４３を貫くように埋め込むが、連結具１０の側周面には、部材３１、４１に差し込むドリフトピン２５を通す側孔１３、１４を設ける。さらに連結具１０には、弾塑性変形を生じさせるため、軸線方向に伸びる長円孔１７を設けるが、長円孔１７は、一方の部材３１の内部に位置する側孔１３と、他方の部材４１の内部に位置する側孔１４と、の間に配置する。このような構成により、連結具１０に引張荷重が作用した際、長円孔１７の外側に位置する領域では、応力が概ね均等に分散し、応力集中を生じることなく衝撃を吸収可能である。また連結具１０は一本の棒状で、その取り扱いは従来のホゾパイプと変わりがなく、施工時の利便性も悪化しない。【選択図】図１
