Description of the Related Art Conventionally used molds of this kind are generally made of hard and thick wood-based plywood or steel plates, and have flanges (including square members) and ribs (including square members) from their peripheral edges. It is an upright structure.

のみならず、該型枠表面に付着したコンクリートを次回
使用の前に取り除かねばならない。Therefore, the conventional formwork generally has a considerably large weight and is not always easy to handle. In the case of a wooden formwork, durability is increased, especially due to an increase in weight due to water absorption and early deterioration due to repeated water absorption and drying. There was also a problem. Moreover, since the surface layer of the hardened concrete adheres to the steel plate or wood board, not only will irregular irregularities occur on the concrete surface after the formwork is removed, but the concrete that has adhered to the formwork surface must be removed before the next use. I won't.

It is not easy to extrude or pull out a slightly deformed structural material, and if it is intentionally carried out, the manufacturing cost will be increased. Furthermore, since aluminum has an affinity for concrete like steel and wood, the problem that hardened concrete adheres to the surface of an aluminum mold remains unsolved.

And the vertical straight convex ribs (16) are arranged to reinforce each other, that is, they are arranged parallel to and intersect with either one of the long and short sides, and on the left and right of the unit frame face plate, respectively, in the center thereof. An area without a linear convex rib is provided in the portion, and a convex rib (17) and a protrusion (18) having six concentric circles are provided in this area. The height of these convex ribs (15), (16) and (17) is 12 ▲ ▼ from the face plate surface in this example. In this way, the convex ribs formed in the middle portion of the back surface of the face plate (19) are attached to the side plate (1

The attachment to the timber (30) is strong. In addition, as shown in FIGS. 4 (a) and 4 (b), one of the side plates (12) and (13), preferably both, is connected to the adjacent formwork (K) and (K). Hole used (12a),
(13a) is drilled. A C-shaped clip or the like is inserted into this hole to connect the adjacent flanges. Therefore, this can be used to connect the unit frames (10) to each other.

ましい。The synthetic resin as the material of the unit frame (10) may be selected from appropriate ones having excellent releasability and durability, such as polypropylene resin, acrylic resin, polycarbonate resin or FRP. The mechanical strength characteristics of the material are also important, and from that point of view, the convex ribs (15) and (16) that are integral with the face plate extend linearly, and the convex rib (17) draws concentric circles in the central portion. It is desirable that they are arranged as follows.

It is desirable to have a size that is an integer fraction of (00 mm is common). As an example, a unit frame in which 6 unit frames (or 5 units) having a length of 300 mm and a width of 600 mm can be arranged side by side in a row, that is, a unit frame having a size of 1/6 (or 1/5) is advantageous. is there. This is because, in general, a dimension of a multiple of 300 mm is often used in civil engineering work, etc., and a dimension change in the middle of construction is also often performed in 300 mm units.

It greatly contributes to improving the efficiency of civil engineering work.
Moreover, since the face plate made of synthetic resin has a good mold releasability of concrete, a beautiful concrete surface can be formed and the conventional extra work of peeling off the adhered concrete is unnecessary. A particularly important advantage is, for example, 600 mm length x 180 width
Compared with the case of injection molding a large mold such as 0 mm as an integrated one, it is easy to manufacture because it is only a fraction of the size of the mold, and it is lightweight and compact, so it can be transported.
Easy to assemble and disassemble.

調節が可能であるから作業が楽である。Further, in the usual formwork, both end portions, particularly corner portions are liable to be damaged by repeated use. In such a case, the entire formwork must be discarded. When forming the formwork by combining,
It is economical because it is only necessary to replace the unit frame of the damaged part, and the work is easy because the formwork size can be adjusted depending on the number of unit frames to be connected.

がある。In addition, since the side plate formed on the short side edge portion of the back surface of the face plate and the brim-shaped portion for mounting the wooden lumber, which is formed at the lower end portion of the side plate to project outward, are formed. ,
When combining a plurality of unit frames to form a form, by mounting wooden lumber on this brim-shaped part and nailing and fixing it, reinforcement of the entire form and strong integral connection can be achieved, and it is also formed on the intermediate face plate The convex ribs formed are formed lower than the height of the side plate so as not to get in the way when nailing from the inside of the side plate toward the wooden lumber on the brim in the area adjacent to the side plate on the short side. Therefore, there are various effects such as the work of connecting the formwork by nailing is easy.
