This formwork structure consists of plywood (a) and (a) arranged side by side at a specified interval.Therefore, a bottom frame (b) with both ends standing vertically is placed on the ground. The lower ends of the veneer plates (a) and (a) are fixed to the bottom frame (b). And plywood (a),
The upper plate (c) is passed to the upper end of (a) and is nailed, and both veneer plates (a) and (a) stand upright while maintaining parallel to each other. Concrete is poured into the space between both plywood (a) and (a).

When the poured concrete has hardened, the veneer boards (a) and (a) are removed, and another rise is created on the base of the created concrete foundation. A plywood board is installed side by side to make a stand-up formwork. By the way, the conventional work of assembling the formwork is very troublesome and can be reused by using the veneer plate as a frame plate, but the cost is also high. Creating the base of the basic concrete and then forming the rising on the base requires about 2 man-hours for the production of the formwork and the pouring of the concrete, as compared with the case of creating the basic concrete at once. It will be doubled.

The fastener has an engaging portion for engaging with a lateral line of the horizontal frame, and also forms a fitting portion for attaching the base frame plate. The locking portion may be a concave groove into which a lateral line fits, or may be provided on an arm end extending from the fitting portion, and an L-shaped receiving portion may be formed on the opposite side of the fitting portion. There is. A crosspiece is set in the receiving portion and supports the base frame plate fitted and attached to the fitting portion. Of course, when the base frame plate is strong, the crosspiece is not required, and therefore the receiving portion may be omitted. The fastener is made of metal, resin,
Or it may be made of concrete.

Conventionally, the base is made of concrete and then the rising is completed to complete the basic concrete. However, if the base and the rising are separately formed as described above, it takes time and labor. The invention is directed to a formwork that can be constructed at the same time. Therefore, a holding tool that is connected to the fastening means is provided, and the support rod of the holding tool on which the rising frame plate is placed can move up and down. However, the means for moving up and down does not matter. The distance between the fastening member and the holding member is adjustable, and the width between both rising frame plates can be arbitrarily changed.

As described above, the base frame plate is arranged on the fastening member and the rising frame plate is arranged on the holding member, so that the mold frame is constituted. Of course, a reinforcement frame for foundation construction is installed in the formwork, and concrete is poured into the formwork. Therefore, basic concrete having a base with a predetermined width and a rising edge is created. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
