等において使用される合成樹脂製の建築用型枠（土木工
事用型枠を含む）に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin architectural form (including a civil engineering form) used in concrete casting work and the like.

Description of the Related Art Conventionally, as a form frame of this type, a hard and thick wood plywood or steel plate is used as a face plate, and flanges (including square members) and ribs (including square members) are formed from the periphery thereof. It is a standing 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。[0003] Therefore, conventional molds generally have a considerable weight and are not always easy to handle, and in the case of wooden ones, durability is particularly high, such as increased weight due to water absorption and early deterioration due to repeated water absorption and drying. There was also a problem. In addition, since the surface layer of the hardened concrete adheres to the steel plate or the wooden board, not only irregularities are generated on the concrete surface after removing the formwork, but also the concrete attached to the formwork surface must be removed before the next use. No.

る、という問題は未解決のまま残る。For this reason, some attempts have been made to extrude or draw an aluminum material into a "harmonic" cross section for the purpose of weight reduction. Extrusion or pulling out of irregularly shaped structural members is by no means easy, and daring to do so would lead to increased manufacturing costs. Further, aluminum has an affinity for concrete, like steel and wood, so that the problem that hardened concrete adheres to the surface of the aluminum formwork remains unsolved.

And the vertically oriented linear convex ribs (16) are arranged so as to reinforce each other, i.e., parallel to and intersect with either of the long and short sides. The area is provided with an area having no linear convex ribs, and in this area, six concentric convex ribs (17) and projections (18) are provided. The height of these convex ribs (15), (16) and (17) is 12 mm from the surface of the face plate in this embodiment. Face plate like this
The convex ribs formed in the middle part of the back surface of (19) are side plates (12),
(13), (40), by forming lower than (40), a long nail (51) is driven from inside the side plate (40) as shown in FIG. , (K) facilitates nailing work when connecting each other. These convex ribs (15), (16) do not necessarily need to be formed entirely lower than the side plate (40),

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) at the center draws a concentric circle. It is desirable that they are arranged as follows.

It is desirable to have a size that is 1 / integer of (typically 00 mm). As an example, a unit frame having a length of 300 mm and a width of 600 mm and having six (or five) unit frames that can be arranged in a row and connected to each other, that is, a unit frame having a size of 1/6 (or 1/5) is advantageous. is there. This is because, in general, civil engineering works and the like often use dimensions that are multiples of 300 mm, and dimensional changes during construction are also often made in 300 mm units.

組立て並びに分解が容易である。According to the present invention, since the synthetic resin formwork for building formwork of the present invention is constructed as described above, it is strong and durable despite its light weight, and it can be used for various types of construction involving concrete casting work. It greatly contributes to improving the efficiency of civil engineering work.
In addition, since the synthetic resin face plate has good releasability of concrete, a beautiful concrete surface can be formed, and the conventional extra work of peeling off the adhered concrete is not required. A particularly important advantage is that, for example,
Compared to the case where a large mold such as 0 mm is integrally formed by injection molding, it is easy to manufacture because a mold of a fraction of the size is sufficient, and it is lightweight and compact, so it can be transported.

する作業が容易である、等の種々の効果がある。In addition, a side plate formed on the short side edge of the back surface of the face plate, and a flange portion for mounting a wooden timber, which is formed by projecting outward at a lower end portion of the side plate, are formed. ,
When a plurality of unit frames are combined to form a mold, a wooden piece of timber is placed on the flange and nailed and fixed to achieve a strong integral connection without reinforcement and displacement of the entire form, Since the convex ribs formed on the surface are formed lower than the height of the side plate in the area adjacent to the side plate on the short side portion, it is easy to nail and connect the mold frames with the side plate portion, etc. There are various effects.
