本発明は、コンクリート打継ぎ型枠とその製造法に関す
る。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a concrete pour form and a method for manufacturing the same.

ドメタル、鋼製ネット等のネット状打止め材に棒状止水
材を付設している。Demoulding used in concrete pouring work
, fx-ps concrete pouring formwork has a rod-shaped water-stopping material attached to a net-like pouring material such as expanded metal or steel net.
しかし、網目から漏れるモルタルが他側の棒状止水材を
覆ってしまうため、これを拭き取るのに甚だ手数を要し
ている。これを放置すると、核部にわずかな隙間を生じ
て止水性が低下するからである。However, the mortar that leaks from the mesh covers the rod-shaped waterproof material on the other side, making it extremely time-consuming to wipe it off. This is because if this is left untreated, a slight gap will be created in the core, reducing the water-stopping property.
上記ネット状打止め材に部分的に鋼板を溶接し、該鋼板
の中央に棒状止水材を付設するとともに、両側に適宜幅

別部材の鋼板を利用したのでは、部材点数が増えるばか
りでなく、手数が増大して、コスト高となる。It has been considered that a steel plate is partially welded to the above net-shaped stopper, and a bar-shaped water-stopping material is attached to the center of the steel plate, as well as a slag guard of an appropriate width on both sides, but it is not possible to use it on walls. Although it is effective when used as a base plate, it is ineffective when used as a foundation board.Also, if a steel plate is used as a separate member, it will not only increase the number of parts, but also This increases the number of steps and costs.

得なくなることがあり、また、厚いと、運搬や建込み時
のハンドリングが悪い等の支障があった。Therefore, the net-like stopper material usually has a thickness of 0.6
~1.5cm is used, but if it is thin, it easily deforms during transportation and construction, and the rod-shaped waterproof material is easy to peel off, and when pouring pre-cast concrete, reinforcing material to prevent deformation is required. Although reinforced with concrete, the unreinforced part bulges out toward the post-casting side due to the pressure of the poured concrete, which may cause the induced edges to curl up and no longer function as a concrete pouring formwork. Also, if it is thick, there are problems such as poor handling during transportation and construction.
本発明は、斯る問題点を解決しようとするものである。The present invention attempts to solve such problems.

ンクリート打継ぎ型枠の製造法にある。In addition, the invention of claim 2 makes a large number of fine cuts for forming a network in a steel plate, leaving a continuous part, and by elongating the steel plate, the periphery of each cut is deformed to form a net. At the same time, a plurality of tall ribs are formed on the remaining continuous plate-like part, and an expandable water stop material is then bonded to the plate-like part between the ribs. It's in the manufacturing method of the frame.

Since we have set up
The rigidity can be greatly increased, there is less deformation during transportation and construction even if the wall thickness is made thinner, the expansible water stop material can be prevented from peeling off due to deformation, and the amount of reinforcing material to prevent deformation can be reduced. It can reduce the number of reinforcing steps, can accurately prevent bulging deformation of pre-cast concrete during pouring, and the resulting curling of edges, and is also lightweight overall, making it easier to handle during work. can.
