Washer for clamping concrete form

Abstract

PROBLEM TO BE SOLVED: To provide techniques whereby a concrete form support member is retained in one or two steps so that even a rectangular or round support member is surely fixed in place to enable a wedge to be driven easily and accurately, with no excessively worn part formed by the driving of the wedge. SOLUTION: In a washer A for clamping a concrete form, having a one-step retaining part 1 and a two-step retaining part 2 at a batter angle 12b, curved parts 6, 10 are projected toward the backs 1a, 2a of the one-step retaining part and/or the two-step retaining part so that curved surfaces 6a, 10a over which a part of a round steel pipe 12a taking place of the batter angle 12b is fitted are arranged within the retaining surfaces 5, 9 of the batter angle 12b. The maximum depth of each curved surface is equal to or smaller than the thickness of a steel plate and openings 7, 11 enabling the lower surface 3a of a wedge to meet the flat part of the back of each retaining part in the longitudinal direction of the retaining part are provided in the curved parts, the width of each opening 7, 11 about equal to the thickness of the wedge.
(57)【要約】 【課題】 コンクリート型枠の支持部材を一段または二 段重ねに押え、角形または丸型の支持部材でも確実に固 定し楔の打ち込みも容易で正確にでき、楔打ち込みによ る極端な摩耗部分が発生しない技術の提供。 【解決手段】 バタ角12bの一段押え部1と二段押え 部2とを有するコンクリート型枠締め付け用の座金Aに おいて、バタ角に代え丸型鋼管12aの一部を嵌着する 湾曲面6a,10aがバタ角の押え面5,9内に配置さ れるように湾曲部6,10を一段押え部または/および 二段押え部の背面1a,2a側に突出し、湾曲面最大深 さが鋼板厚み以下にして形成し、押え部の長手方向に向 け楔下面3aを押え部の背面平坦部に面合可能とする開 口部7,11を略楔の厚みと同幅で湾曲部に設けた構 成。
