SHORT STRUT
To provide a short strut that can be efficiently installed even if an excavation region is narrow.SOLUTION: A short strut 1 provided on an earth retaining support that is temporarily disposed on an excavation region has a rod-like inside strut member 3, a cylindrical first outside strut member 4 screwed on one side in an axial direction of the inside strut member 3, and a cylindrical second outside strut member 5 screwed on the other side in the axial direction of the inside strut member 3. A first male screw 33 and a second male screw 34 are formed on one side in the axial direction of the outer periphery and on the other side in the axial direction of the outer periphery, respectively, of the inside strut member 3. The first male screw 33 and the second male screw 34 are reverse to each other. A first female screw 43 to be screwed onto the first male screw 33 is formed on the inner periphery of the first outside strut member 4. A second female screw 53 to be screwed onto the second male screw 34 is formed on the inner periphery of the second outside strut member 5.SELECTED DRAWING: Figure 2
【課題】掘削領域が狭隘な場合でも効率よく設置することができる切梁を提供する。【解決手段】掘削領域に仮設される土留め支保工に設けられる切梁１において、棒状の内側切梁部材３と、内側切梁部材３の軸線方向の一方側に螺合する筒状の第１外側切梁部材４と、内側切梁部材３の軸線方向の他方側に螺合する筒状の第２外側切梁部材５と、を有し、内側切梁部材３は、外周の軸線方向の一方側に第１雄ねじ３３が形成され、外周の軸線方向の他方側に第２雄ねじ３４が形成され、第１雄ねじ３３と第２雄ねじ３４とは、互いに逆向きのねじであり、第１外側切梁部材４は、内周に第１雄ねじ３３と螺合する第１雌ねじ４３が形成され、第２外側切梁部材５は、内周に第２雄ねじ３４と螺合する第２雌ねじ５３が形成されている。【選択図】図２
