EARTH SUPPORTING MATERIAL AND END METAL PART USED FOR THE SAME

PROBLEM TO BE SOLVED: To provide an earth supporting material and an end metal part used for the same with which a temporary member required in a conventional case may be omitted, thus the number of the temporary members may be minimized even in a case which requires deep digging; and thereby, in a case where an end metal part made of steel material which is served as an extending part at an end part of the earth supporting material is enclosed in a wall, interference with a bar arrangement may be reduced as much as possible.SOLUTION: As an extending part, such as an angle brace and a cut beam, at an end part of an earth supporting material, an end metal part 8 made of steel material is arranged in an orthogonal direction of a wall 6 in an integrated manner with the wall 6. 【課題】本来必要な仮設部材を省略することが出来るので、大深度掘削の物件においても仮設部材を必要最小限にとどめることが可能となり、しかも、そのために山留め支保工材の端部に延設するものとして、鉄骨材による端部金物を壁体内に納める場合に配筋との干渉を極力少なくできる山留め支保工およびそれに使用する端部金物を提供する。【解決手段】火打ちや切梁等山留め支保工材の端部に延設するものとして、鉄骨材による端部金物８を、壁体６の直交方向に位置せしめ、該壁体６と一体とする。【選択図】 図１
