SOLUTION: Fixing hardwares to fit the lower end and the upper end of an angular pipe column 5 respectively are fixed to a lower sash bar and an upper sash bar at a space corresponding to the width of a sheathing board 3. The angular pipe column 5 has a column side hole 5B1 in the inner face 5B at a preset space to the vertical direction, a rod penetration hole 5C1 corresponding to the outer face 5C and a columnar center support 5D formed at the same height as the thickness of the sheathing board 3 and attached to the center of the inner face 5B in the vertical direction. A P-cone 7 is formed of a screw rod 7B1 threaded to a fastening rod 8 and a support 7B2 threaded to a separator 9 to resist the pressure of concrete. A crosscut 10 is connected to the fastening rod 8 to complete a form. Assembling work is thus efficiently done.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a formwork for placing concrete and a method of assembling the formwork using the formwork. Specifically, the pressure of the concrete acting on the weir plate 3 is applied to the central receiving portion 5 fixed to the square pipe support 5.
D is transmitted to the square pipe support 5 with the fulcrum as a fulcrum, and the externally applied stress received by the formwork is resisted against the concrete pressure by the tensile strength of the screw bar portion 7B1 of the P-container and the separator 9 penetrated through the square pipe support 5. It is something that can be done.

[0002]

2. Description of the Related Art Heretofore, this type is as follows. Conventionally, the general formwork method is
Vertical pull (pier or single pipe) supports the concrete pressure on the weir board, and vertical pull is supported by horizontal pull. The horizontal draw is connected to the separator and further connected to the opposite horizontal draw, thereby canceling each other's pressure.

[0003]

The above-mentioned prior art has the following problems. A. Since the pressure is dispersed by the three-layer structure including the weir board, the vertical draw, and the horizontal draw as described above, there is a problem that the amount of the material is large and the construction time is required. B. The weir is nailed in order to connect the weir to the adjacent weir through the pier. C. A hole must be made for the separator. D. For the above reasons, in the conventional method, the consumption rate of the dam is large and the conversion rate is low. E. FIG. Regarding the workability, saws and gennows are frequently used, and the setup of the formwork is complicated, and the work is difficult unless some skilled craftsmen are used. The present application has been made in view of such problems of the related art, and has as its object to provide the following. A. This is a formwork assembly method that can be used by unskilled workers without using nails. B. By reducing the number and weight of formwork materials, the economics related to the management of materials, such as the reduction of material maintenance costs, storage space, and transportation costs, are improved. C. Conventionally, the number of times of diversion of a weir board is generally about three times, because nailing or drilling of a hole for a separator is performed, and the diversion rate is extremely low. By using a dam of the same standard, not driving in nails and not drilling holes for separators, the conversion rate of dams can be greatly increased. D. Since the assembling method does not use a lot of saws and knuckles, the assembling can be performed easily and quickly.

[0012]

Since the present invention is configured as described above, the following effects can be obtained. 1. The conventional formwork assembling work starts by cutting the dam plate to a predetermined size and attaching a crosspiece. However, the present invention does not need to do so, and the assembling work can be started from the beginning.
In addition, since it is not necessary to perform a difficult operation such as nailing the surfaces of the adjacent weir plates together, the assembling operation can be easily mechanically advanced, and the workability is good. In addition, since the work can be performed mechanically as compared with the conventional construction method, the construction can be performed even by an unskilled worker. 2. The number of times the divert board has to be diverted has been greatly increased because it is not necessary to make holes for separators in the dam or drive nails to attach a pier, etc., and it is not necessary to cut the dam into predetermined dimensions. It can be increased and is economical.
(By not making holes for nailing and separators,
The diversion rate of the weir can be greatly increased. Since the work of nailing and fixing the pier to the weir and the work of drilling the separator with a drill on the weir are unnecessary, it can be performed by unskilled workers. ) 3. With the multi-use of crests, the possibility of developing a rental business for a complete set of materials can be expected, even for formwork materials that previously accounted for a high proportion of consumable materials. (The multi-purpose use of dams reduces the wear rate. This contributes to the improvement of environmental issues in terms of resource saving. Conventional wooden materials, dams and piers are consumable materials, so The material could not be a rental product, but the construction method of the present application has the potential for a formwork material rental business.) Since the weir can be removed even after the completion of the formwork assembly, piping and wiring can be easily installed by removing the weir even after the completion of the formwork assembly.

5. Since the square pipe support is a lightweight material, the workability of transportation and assembly is good. 6. When used in combination with a decorative formwork having a finished surface made of concrete to have a design property, the economical efficiency of the material cost of the decorative formwork attached to the weir board is further increased due to multiple conversions. 7. The left and right sides of the weir plate 3 are the inner surfaces 5B of the square pipe struts 5,
Since the state is sandwiched between the central receiving portion 5D and the personal computer 7, the weir can be strongly supported. In this case, no special reinforcement is required on the left and right sides of the weir plate, so that no labor is required and the whole can be made inexpensive. 8. Since the receiving portion 8B of the tightening rod 8 and the threaded rod portion of the P-con- trol are screwed and connected to each other, there is no need for a shaft foot of the P-con- sistor as in the related art, so that no labor is required. 9. The gap between the adjacent dams 3 is set to the width 5D3 of the center receiving portion 5D.
As the concrete can be exposed, the width of the vertical streaks appearing on the exterior can be reduced. In addition, since the gap between the adjacent weir plates 3 can be narrowed, when the receiving portion 8B of the tightening rod 8 penetrated from the tightening rod penetration hole 5C1 and the threaded rod portion of the P component are screw-connected to the P component side, Even if a washer is not used, the damping plate can be pressed and tightened with a P-con.
