JIG FOR CONSTRUCTING EARTH RETAINING STRUCTURE, AND CONSTRUCTION METHOD OF EARTH RETAINING STRUCTURE
To provide a jig for constructing an earth retaining structure and a construction method of an earth retaining structure making a construction of an earth retaining structure easy.SOLUTION: When constructing an earth retaining structure formed by connecting a plurality of earth retaining members each having end edges on which flange portions are formed, a jig for constructing an earth retaining structure aligns positions of connection holes formed in the flange portions and holds the earth retaining members in a state in which the flange portions overlap. The jig for constructing an earth retaining structure comprises: a fixed piece with a tip at which a first clamping portion is provided in which a protrusion inserted into the connection hole is formed; a lever portion attached to the fixed piece via a link so as to freely oscillate; and a movable piece which is attached to the fixed piece so as to freely rotate, with a tip at which a second clamping portion is provided in which a recessed portion into which the protrusion is inserted is formed, and which is constituted such that the second clamping portion becomes separated from or close to the first clamping portion in conjunction with oscillation of the lever portion. The first clamping portion further comprises a collar portion which is formed so as to protrude outwardly from an outer peripheral surface of the protrusion. The second clamping portion further comprises a flat face which is formed around the recessed portion. An end face of the collar portion and the flat face face each other with a prescribed distance in a state in which the lever portion and the fixed piece are brought into closest with each other.SELECTED DRAWING: Figure 5
【課題】土留構造の構築を容易にする土留構造構築用治具及び土留構造の構築方法を提供する。【解決手段】本発明に係る土留構造構築用治具は、端縁にフランジ部が形成されている複数の土留部材を連結して形成される土留構造を構築する際にフランジ部に形成された連結孔の位置を合わせ、かつフランジ部を重ねた状態で保持する土留構造構築用治具であって、連結孔に挿入される突出部が形成された第１挟持部が先端に設けられた固定片と、固定片にリンクを介して揺動自在に取り付けられたレバー部と、固定片に回動自在にとりつけられ、突出部が挿入される凹部が形成された第２挟持部が先端に設けられ、レバー部の揺動に連動して第２挟持部が第１挟持部に対し離合するように構成された可動片と、を備え、第１挟持部は、突出部の外周面から外側に張り出すように形成された鍔部を更に備え、第２挟持部は、凹部の周囲に形成された平坦面を更に備え、鍔部の端面と平坦面とは、レバー部と固定片とを最も近づけた状態において、所定の距離をもって対向する。【選択図】図５
