The wooden formwork panel is fixed to the panel fitting part of the formwork base, and as a fixing means, a plurality of holes are drilled in advance at predetermined positions in the wooden formwork panel, and appropriate screws are inserted into the holes. It was fixed to the formwork base with nails, etc.

要となる場合もあった。[Problems to be Solved by the Invention] However, with conventional means, it is necessary to accurately cut the wooden formwork panel to predetermined dimensions, and it is also difficult to accurately drill a plurality of holes at predetermined positions in the wooden formwork panel. However, the problem was that the assembly was troublesome and time-consuming. In particular, wooden formwork panels (
For example, the surface of plywood (plywood) that comes into contact with poured concrete is severely damaged, and it is necessary to install compatible wooden formwork panels relatively frequently, making assembly difficult and economical. There was also a problem. Moreover, since the formwork panels are fixed to the formwork base by inserting appropriate screws, nails, etc. into the multiple holes drilled in the formwork panels, the heads of screws, nails, etc., are inserted into the concrete surface. In some cases, the shape of the part remained, making it impossible to form the poured concrete surface neatly, and repair work was required.

が完成する。Next, an example of the use of the concrete formwork A of the present invention will be described. First, a plurality of concrete formworks A are connected to each other via formwork connectors 25 to form a wall formwork of a predetermined size. . Then, this is placed at a desired position on the concrete slab, and the separator 20 is inserted into the separator insertion space surrounded by the corner inclined surfaces 9 of the plurality of concrete forms A, and the separator 20 is inserted through the seat plate 21. Then, screw the nuts 22 to construct the wall formwork. If the surface of the face plate 2 of the formwork base 1 is damaged due to repeated use of the concrete formwork A (or when the formwork base 1 is damaged), remove the mounting screws 15 and then remove the formwork base. 1 and the reinforcing body 10 are separated,
The separated reinforcing body 10 is attached to the new formwork base 1, and these are fixed with the mounting screws 15 to form the concrete formwork A.
is completed.

大な省力化が図れるようになる。Therefore, according to the concrete formwork according to claim 1, the structure of the concrete formwork itself becomes simple and suitable for mass production, and the reinforcement body increases the strength of the concrete formwork itself. It has increased rigidity, is extremely strong, durable, and lighter than traditional concrete formwork. In addition, since sufficient strength can be obtained, there is no need for thick timbers or the like to hold down the concrete formwork from the outside, and a great deal of labor can be saved when constructing wall formwork, etc.

補修作業が不要となる。[0019] Furthermore, since the face plate portion, which is the contact surface of the poured concrete, is made of a suitable synthetic resin material,
Concrete is difficult to adhere to, and the surface of the poured concrete can be formed very neatly, eliminating the need for conventional repair work.

ようになる。Furthermore, since corner slopes are formed at the four corners of the formwork base 1, the separator through holes can be constructed using the corner slopes, and the separator can be formed in the concrete formwork itself. This eliminates the need to drill through holes.

ようになる。Further, according to the method for producing concrete formwork according to claim 2, the concrete formwork can be assembled by simply attaching the reinforcing body to the formwork base and fixing the reinforcing body to the formwork base via the mounting screws. As a result, the assembly of concrete formwork can be performed extremely easily and quickly without requiring any skill, and the assembly process is hassle-free and efficient, greatly reducing the manpower and time required for assembly. Labor-saving,
Concrete formwork can be provided at low cost. Moreover, it is also possible to manufacture in advance a large quantity of only the formwork bases, which are relatively easily damaged, so that there is no waste in transportation, storage space, and management labor. Furthermore, since the mold base is integrally molded from a synthetic resin material containing reinforcing fibers, it becomes possible to form a mold base with considerably high strength relatively easily.
