。Although this problem could be improved by stacking and connecting the vertically adjacent groups of formworks, shifting them by half a pitch in the horizontal direction, and making the vertical joints discontinuous, the problem still remains.

本発明は、かかる問題を考察し、上記の如き不都合を解
消して、大巾な工発節減を達成できるコンクリート型枠
を提供せんとするものである。The present invention considers these problems and aims to provide a concrete formwork that can eliminate the above-mentioned inconveniences and achieve a significant reduction in construction labor.

あることを特徴とする。The concrete formwork according to the present invention, when pieces of the same shape and size are stacked and connected side by side in multiple rows and in multiple stages, forms a series of concrete forms without forming continuous linear joints in either the juxtaposition direction or the stacking direction. It is characterized by being configured in a shape that forms a flat concrete pouring surface, such as a regular hexagonal shape.

成できるに至った。According to this, continuous linear joints are not formed either in the juxtaposition direction of the formwork or in the stacking direction, and therefore, the concrete lateral pressure acting on the abutting joints of adjacent formworks is , can be distributed to multiple locations with different phases, which reduces the load on each U-clip, and also suppresses the outward bulge of the formwork group. Frame supports can be saved and reduced in terms of materials, materials, and number of parts, and the labor required for assembling and disassembling them has also been reduced, making it possible to achieve a significant reduction in overall construction costs. .

以下、本発明の実施態様を図面に基づいて説明する。Embodiments of the present invention will be described below based on the drawings.

ンクリート型枠Ａを構成しである。As shown in Figures 1 to 4, a flat plate member 1 that forms a concrete pouring surface in the implosion is made of plywood into a regular hexagonal shape (one side is 2
0 to 50 cIIL), and a peripheral edge member 2, which is made of a metal material such as stainless steel and bent into a shape that can come into contact with the back collapse and peripheral end surface of the flat plate member 1, is formed around the back surface of the flat plate member 1. The portions 2a are connected via a plurality of screws 3 in a posture perpendicular to the plate surface of the flat member 1 to constitute a concrete formwork A.

ためのものである。Reference numeral 4 denotes a hole drilled in the protruding portion 2a of the peripheral edge member 2, and the abutting peripheral edge members 2, 2 of the adjacent formworks A, A are fixed to each other by inserting a U clip 7, which will be described later, into the opposing holes 4, 4. It is for connecting.

とになる。In this state, the contact joints 6 of the adjacent formworks A, A, etc. are wavy in both the formwork juxtaposition direction (horizontal direction) and the stacking direction (vertical direction). The concrete lateral pressure applied to the series of flat concrete placement surfaces formed on the inner surface of the connected formwork group A is distributed to the corrugated joints 6. It will work.

The required strength and number of connecting fittings 10 for connecting to ... can be reduced compared to the conventional case.

又、その扁平板部材１は合板製であるから、これの変形
、損耗時の取替えを容易かつ安価に行なえる。Further, since the flat plate member 1 is made of plywood, it can be easily and inexpensively replaced when it is deformed or worn out.

る。However, the combination of the fact that the peripheral edge member 2 is made of metal, that the reinforcing member 5 is attached, and that the button and the whole are made into a regular hexagon compensates for the decrease in strength due to the fact that the flat plate member 1 is made of plywood. The formwork can be provided with sufficient strength to overcome the problems.
