SHORT STRUT JACK INSTALLATION BOX AND LANDSLIDE PROTECTION STRUT
To provide a short strut jack installation box and a landslide protection strut of which a short strut jack bears only the axial force acting on a short strut, not the bending force and the shearing force, and the short strut jack can be installed at any position in the axial direction of the short strut.SOLUTION: An inner frame 12 and an outer frame 11 internally contacting the inner frame 12 are provided. Provided inside is a short strut jack 3 that introduces an axial force to a landslide protection strut 1. The outer frame 11 and the inner frame 12 are arranged so as to be slidable in opposite directions to the axial direction of the short strut as the short strut jack 3 expands and contracts. The outer circumference of the short strut jack 3 and the inner frame 11 are separated from each other. It is structured such that the axial force acting on the landslide protection strut 1 is transmitted by the short strut jack 3, and the bending force and the shearing force acting on the landslide protection strut 1 are transmitted at the contact surfaces of the outer frame 11 and the inner frame 12. A friction reducing material is interposed on the contact surface between the outer frame 11 and the inner frame 12.SELECTED DRAWING: Figure 1
【課題】切梁ジャッキは切梁に作用する軸力のみを負担し、曲げ力とせん断力は負担しないようにして、切梁ジャッキを切梁軸方向の任意の位置に設置できるようにした切梁ジャッキ設置ボックスおよび山留切梁を提供する。【解決手段】内枠12と内枠12が内接する外枠11を備えている。中に山留切梁１に軸力を導入する切梁ジャッキ３を備えている。外枠11と内枠12は切梁ジャッキ３の伸縮に伴って、切梁軸方向の相反する方向にスライド可能に配置する。切梁ジャッキ３の外周と内枠11間を離間させる。山留切梁１に作用する軸力は切梁ジャッキ３が伝達し、山留切梁１に作用する曲げ力とせん断力は外枠11と内枠12との当接面で伝達するように構成する。外枠11と内枠12との当接面に摩擦低減材を介在する。【選択図】図１
