ンクリート型枠の組立てにおいて、縦横のばた材
を使用する場合は座金の脚が長く、一方、横ばた
材のみを使用する場合は座金の脚が短かい。(Prior art) This type of washer for concrete formwork connectors has long legs when vertical and horizontal beams are used in assembling concrete formwork, whereas only horizontal beams are used. In this case, the legs of the washer are short.

そこで、従来は、実公昭56−30608号公報に記

（考案の効果） この考案は、次のような顕著な効果を有する。(Effect of idea) This invention has the following remarkable effects.

(1) この考案の座金は、型枠の組立てにおいて、
縦横のばた材を使用する場合と、横ばた材のみ
を使用する場合の両方の工法に兼用で用いるこ
とができるから、型枠の組立てには１種類の座
金だけを用意しておけばよくて経済的である上
に、取扱いおよび作業上における手間を節減し
得て作業性が向上する。(1) The washer of this invention can be used when assembling formwork.
It can be used for both methods of construction, such as when using vertical and horizontal beams, and when using only horizontal beams, so you only need to prepare one type of washer when assembling the formwork. Not only is it economical at best, it also reduces handling and work effort and improves work efficiency.

(2) 座金は、縦片からその両端の長短の脚にわた
り、それらの幅方向における断面がＳ字形で、
半部づつが互いに反対面側へ突出する長さ方向
のリブに形成されているから、その両リブによ
り全体にわたつて連続的に補強され、堅牢で損
傷することがない。(2) The washer extends from the vertical piece to the long and short legs at both ends, and has an S-shaped cross section in the width direction.
Since each half is formed with longitudinal ribs that protrude toward opposite sides, the entire structure is continuously reinforced by both ribs, making it sturdy and undamaged.

(3) 座金の２個のくさび挿入孔は互いに齟齬して
いるから、座金のくさび挿入孔を設けた部分も
堅牢である。(3) Since the two wedge insertion holes of the washer are inconsistent with each other, the portion of the washer where the wedge insertion holes are provided is also strong.

(4) 型枠の組立てにおいて、縦横のばた材を使用
する場合と、横ばた材のみを使用する場合の何
れの工法に用いるときも、常にくさびが座金の
縦片の外面に正確に密接し、振動等によつてく
さびが浮くことはなく、堰板に対しばた材を適
切に押当てて型枠を堅固に組立て保持すること
ができる。(4) When assembling formwork, whether using vertical and horizontal beams or using only horizontal beams, always make sure that the wedges are placed exactly on the outside of the vertical pieces of the washer. Since the wedges are in close contact with each other, the wedges will not float due to vibrations, etc., and the formwork can be firmly assembled and held by appropriately pressing the flap material against the weir plate.

(5) 構造が簡単で、容易安価に製作できる。(5) It has a simple structure and can be manufactured easily and inexpensively.
