FOUR-SIDED FRAME FOR EARTH RETAINING
PROBLEM TO BE SOLVED: To provide a four-sided frame for earth retaining using a telescopic method by fluid pressure, which can smoothly and naturally contracting the frame after use.SOLUTION: Four frames A incorporate a drive mechanism including a cylinder 3 and a piston 4 and are elongated by injecting a fluid pressure into the cylinder 3 and are constricted by the return spring 10 when the fluid pressure in the cylinder 3 is released, and are assembled in a rectangular shape via a corner connection fitting B. The frame A is formed of an outer pipe 1 and an inner pipe 2 which are slidably fitted. Slide members 14 and 15 made of a resin material having a small friction coefficient are provided on an inner peripheral surface of the outer pipe 1 and an outer peripheral surface of the inner pipe 2 in the vicinity of a fitting end portion of the outer pipe 1 and the inner pipe 2.SELECTED DRAWING: Figure 4
【課題】流体圧力による伸縮方式を用いた土留め用枠体であって、使用後にフレームを円滑に自然収縮させることができる四面土留め用枠体を提供する。【解決手段】シリンダー３及びピストン４を含む駆動機構を内蔵し、シリンダー３に流体圧力を注入することにより伸張し、シリンダー３内の流体圧力を開放すると復帰スプリング１０によって収縮するように形成された４本のフレームＡがコーナー連結金具Ｂを介して方形状に組み付けられ、フレームＡがスライド可能に嵌合された外管１並びに内管２から形成され、外管１と内管２の嵌合端部近傍で、外管１の内周面及び内管２の外周面に、摩擦係数の小さな樹脂材料からなるスライド部材１４、１５を設ける構成とした。【選択図】図４
