てる作業に非常に多くの時間と労力とを要している。In this case, veneer plywood is widely used as a concrete formwork for forming the above-mentioned assembly frame, and the veneer plywood frame formed in a predetermined size is connected and assembled by using a reinforcing material. A concrete assembling frame is formed to form a wall surface of a predetermined concrete casting space. In this case, assembling a large number of veneer plywood frames requires a great deal of time and labor. .

するものである。As a prior art of such a paneled concrete form, there is a structure as shown in a sectional view of FIG. 13. In this concrete form, a large number of panels 51 are connected by U-shaped pins 52. The assembled panel frame is maintained at a predetermined interval by a separator screw 53, and a reinforcing member 55 is fixed to the back surface by a fastening rod 54 to form a concrete assembly frame 56.

There is an invention described in JP-A-56-9563. However, in the concrete formwork of the present invention, since a large number of reinforcing ribs are formed integrally with the panel so that the reinforcing material 55 is not required, the reinforcing material 55 is not required, but one formwork is required. The weight of the work significantly increases, and efficient work cannot be performed in a complicated work site.

クリート型枠を必要とする。As described above, when a concrete building is constructed with a concrete form made of FRP as described above, the concrete form having the same shape is continuously connected on a wide flat surface. The casting space S may be formed. For example, as shown in a perspective view of FIG. 12, a concrete building has portions of various shapes such as a continuous wall portion P, a column portion Q, and an inclined portion R. Therefore, not all concrete placing spaces can be formed with the above-mentioned conventional concrete formwork. Particularly, in recent years, concrete structures of various shapes have been constructed, and in order to form the concrete casting space of these various shapes with the concrete form made of FRP, concrete forms of various sizes are required.

As described above, it is very difficult to form a concrete building by combining concrete forms of various sizes as described above. In addition, since the work site for forming a concrete building by combining concrete forms of various sizes is very complicated, it is more difficult to form a concrete assembly frame that allows quick work at the work site. , Not yet realized.

After placing the removed members and the like in a safe place, the fastener 2 is removed and the formwork 1 is dismantled. However, these operations are very complicated because it is necessary to disassemble a large number of members. In particular, when disassembling the reinforcing member 5, when the wedge 7 is removed from the fastener 4 by hitting with a hammer or the like, a downward movement is required. Since the reinforcing member 5 falls, it is necessary for an operator to remove the reinforcing member 5 while supporting it by hand. This reinforcing material 5 is heavy (for example, one is 16 kg).
), The removal work while supporting with one hand is extremely hard work. In addition, such a concrete form 1
In most cases, the disassembly work is performed on an assembling scaffold in the air, so that the work is performed in an unreasonable posture in a place with poor feet, which is a very inefficient work.
