Further, the work performance is improved by forming a seat tool 11 by concrete and burying it and fitting it only through insertion.SELECTED DRAWING: Figure 1

Description

せき板の連結する端部より12ミリ程度後退した位置に、型枠連結具に具備するガイドピンが貫通する貫通孔を一定の間隔に複数設けた桟木又は金属型材等の縁リブを固定してなるコンパネフォームと称するシステム型枠及び、せき板の連結する端部に桟木又は金属型材等の縦リブを固定してなる型枠パネルと称するシステム型枠において、組立または解体に関するコンクリート型枠締結具の形態に関する物である。 At a position about 12 mm retreated from the end where the weir is connected, a plurality of through-holes are provided at regular intervals through which the guide pins of the formwork connector pass. Concrete formwork fasteners for assembly or dismantling in system formwork called concrete panel form and system formwork called formwork panel in which vertical ribs such as crosspieces or metal forms are fixed to the ends of connecting dams It relates to the form of

対向する型枠せき板間を支持するセパレート部材の形態に関する物である、又は、型枠組立に使用する、部品である。 It relates to the form of a separate member that supports between opposing formwork dams, or is a part used for formwork assembly.

コンクリート構造物である壁体の施工時におけるコンクリートの打設に際しては、構造物の骨格と補強材になる鉄筋の配筋が完了したのち、その両側にシステム型枠(以下、単に型枠と言うことがある)をそれぞれ連結配置し、対向する型枠間の所要間隔を維持するように丸セパを配置するとともに、コンクリート型枠の背面を支持する横バタ材を配置固定し、型枠間にコンクリートを流し込む事によりコンクリート構造物の施工が行われる。 When pouring concrete during the construction of a wall, which is a concrete structure, after the reinforcement of the structure's skeleton and reinforcing bars is completed, system formwork (hereinafter simply referred to as formwork) is placed on both sides. ) are connected to each other, and a round separator is placed to maintain the required spacing between the opposing formwork, and the horizontal butter material that supports the back of the concrete formwork is arranged and fixed, and between the formwork Concrete structures are constructed by pouring concrete.

対向する型枠間の所要間隔を維持するように丸セパの両端にPコンと称する座具を螺合して取付け、コンクリート打設固化後、回転させて抜取り、その抜き後を防水モルタル等で埋込む方法が一般的であるがこの方法では取付け及び取外しに手間がかかる他、Pコン抜取り後を防水モルタル等で埋込むため、工期が延びる欠点がある。 In order to maintain the required distance between the facing molds, a fitting called a P-con is screwed to both ends of the round separator and attached. The embedding method is common, but this method requires time and effort to install and remove, and has the disadvantage of extending the construction period because it is embedded with waterproof mortar etc. after removing the P concrete.
