抜きが斜めになると連結鍔板同志が当接して型枠の引き
抜きが不良となり、作業性の点において非常に厄介であ
るという問題点である。In order to form a retaining wall, the formwork is connected vertically and horizontally, standing upright at the desired position, concrete is allowed to flow between the formwork and the panel plate standing upright behind the formwork, and after the concrete solidifies, the formwork is formed. When removing, there is a connecting brim plate protruding from the periphery of the form,
The formwork must be pulled out linearly, and if the pullout is skewed even a little, the connecting collar plates will come into contact with each other and the formwork will be pulled out poorly, which is a problem in terms of workability. .
本考案は、この問題点を解決しようとするものである。The present invention seeks to solve this problem.
添付図面を参照して本考案の構成を詳述すると次の通り
である。The structure of the present invention will be described in detail with reference to the accompanying drawings.

ト型枠に係るものである。In a concrete formwork in which a connecting brim plate 4 is provided around the periphery of the base plate 1 of the formwork 3, the adjacent formwork 3 when the formwork 3 is juxtaposed by a predetermined length a from the base of the connecting brim plate 4. Of the connecting flange plate 4 are provided so as to be in contact with each other to form a concrete outflow preventing portion 8 having a predetermined length a.
Forming the thinned portion 9 by providing the following thinly, the adjacent molds 3
A space 20 is formed between both of the connecting collar plates 4 when they are installed side by side, and the linear withdrawal of the mold 3 at the time of demolding is restricted to the predetermined length a only. It relates to a characteristic concrete formwork.
型枠３を縦横に並設して連結し、所定位置に型枠列を立

ることはない。Form frames 3 are vertically and horizontally arranged side by side and connected, and form line rows are erected at predetermined positions. A panel plate 7 is erected on the rear side of the mold row with a predetermined gap, and concrete is poured between the mold row and the panel board 7. The concrete outflow prevention portion 8 is provided at the base of the connecting flange plate 4 so as to be in contact with the connecting flange plate 4 of the adjacent molds 3.
Since concrete is formed, concrete does not flow out of the mold 3.
コンクリートが固化した後、型枠３を取り外すとコンク
リート擁壁が形成される。After the concrete is solidified, the formwork 3 is removed to form a concrete retaining wall.
この型枠３を取り外す際、連結鍔板４の基部から所定長

とは多少型枠３の引き抜きが斜めになっても良い。When the mold 3 is removed, the base plate of the connecting collar plate 4 is thinned from the base to a predetermined length a and thereafter, and a gap 20 is formed between the connecting flange plates 4 when the adjacent mold frames 3 are juxtaposed. Therefore, if the formwork 3 is pulled out linearly only for the predetermined length a where the concrete outflow prevention portion 8 having a large thickness exists, even if the formwork 3 is slightly pulled out thereafter. good.
