The connecting plate 20 is provided with a nail hole 20a. After the pier 16 is inserted into the engaging hole 12a, the pier 16 can be nailed to the pier 16 through the nail hole 20a. .

Next, referring to FIG. 4, the auxiliary formwork panel 15 used together with the formwork panel 10 of the present invention will be described. A reinforcing bar 22 is fixed to an upper end of a plywood 21, and a back surface 21a of the plywood 21 A plurality of piers 16 each having a thickness of, for example, 24 mm × 49 mm are fixed to the plywood 21 so as to protrude from the plywood 21. It is good to do.

According to the method of the present invention (claim 1), a guide member 12 fixed to the back surface of a reference form panel 10 having at least a front surface made of fiber reinforced resin or aluminum and having a certain dimension is projected from the panel 15. The reference form panel 1 is formed by engaging the crosspiece 16 of the auxiliary form panel 15 of any size provided with the crosspiece 16 to integrate the reference form panel 10 and the auxiliary form panel 15.
This is a method for forming a mold panel 30 having an arbitrary length larger than the dimension 0.

The present invention is configured as described above,
Hereinafter, the operation will be described. In FIG. 5 and FIG. 6, a certain dimension (length or height) due to the odd dimension appearing
In the case where an irregular-shaped form panel becomes necessary, the auxiliary form panel 15 is cut to the required size and height. The pier 16 of the auxiliary form panel 15 is connected to the guide member 12.
Are inserted into the engaging holes 12a, and
Then, the reference form panel 10 and the auxiliary form panel 15 are integrally combined by hitting a nail (not shown), and a reinforcing bar 19 is fixedly attached to the lower end of the reference form panel 10 so as to have a predetermined length. The formwork panel 30 is manufactured.

As another manufacturing method, the reference form panel 10
The guide member 1 is made to protrude by the insufficient length (height) from
Only the crosspiece 16 is inserted into the second engaging hole 12a, and the nail hole 20a is inserted.
After being fixed to the reference formwork panel 10 by nailing, the plywood 21 may be nailed to the crosspiece 16 to produce the pier.

The shape of the auxiliary form panel 15 is not limited to a rectangular shape, but can be easily manufactured according to necessity even in a modified shape having different heights in right and left directions.

When the previously used auxiliary form panel 15 is reused, it can be used as it is if it has the same dimensions as the previous use, but it is too long,
Even if it is too short, it can be easily reused by appropriately modifying the auxiliary form panel 15.

More specifically, if the length is too long, the lower end of the plywood 21 of the auxiliary formwork panel 15 is cut in accordance with the required length, and the crosspiece 16 is cut off until the panel 11 and the plywood 21 abut. The auxiliary form panel 15 having the required length can be easily manufactured by inserting the auxiliary form panel 15 into the necessary length simply by inserting the auxiliary form panel 15 into the engaging hole 12a and nailing it to the crosspiece 16. After pulling out from the engagement hole 12a and nailing the pier 16 to the connecting plate 20, the insufficient plywood 21 is nailed to the pier 16 so that it can be easily manufactured on site.

As described above, the irregular form panel 30
Cuts the wooden auxiliary form panel 15 to predetermined dimensions,
Since the form panel 30 of an arbitrary length can be manufactured by a simple operation simply by inserting the crosspiece 16 into the engagement hole 12a, it can be manufactured extremely easily in a short time in the field.

At the construction site, first, the reference formwork panel 10 is used to sequentially form a framework, and then the reference formwork panel 10 is used.
A frame is formed by assembling the form panel 30 manufactured according to the actual size as described above to an irregular-shaped portion that cannot be assembled by itself, but the adjacent standard form panels 10 or form panels 30 are connected to each other. A clip (not shown) is inserted into the coupling hole 14a, and the two reference form panels 10 are inserted.
Alternatively, the reinforcing plates 14 of the formwork panel 30 are sandwiched between the clips so that they are in close contact with each other to be joined, and then the panels 10, 3 are traversed through the joined panels 10, 30.
A plurality of connecting pipes (not shown) are provided on the back side of the slab 0 to reinforce it so that it can withstand the force at the time of concrete casting, and the ready-mixed concrete is poured into the void formed by the panel 10 or 30 and solidified. Finish in the prescribed shape.

The reference form panel 10 comprises a synthetic resin panel 11 whose surface is covered with a fiber reinforced resin or aluminum 11b, and a pipe-shaped guide member 12 made of a metal such as aluminum or a synthetic resin. Since the panel 11 is lightweight, it can be easily handled on site, and the panel 11 hardly deteriorates due to use, it can withstand dozens of times of diversion, and the timber, a valuable resource, can be used. It is possible to reduce the required stock of formwork panels and reduce the size of the material storage area without wasteful consumption, thereby reducing construction material costs.

[0031]

According to the present invention, as described above, at least the front surface of a panel made of fiber reinforced resin (FRP) or aluminum is fixed to the back surface of a panel, and the crosspiece of another form panel is engaged with the guide member. Can be easily assembled on site to adjust the length (height) of the form panel to the required dimensions. As a result, the number of steps for assembling the form panel is greatly reduced. The required stock of formwork panels can be reduced, so that the material storage space can be reduced, and the construction cost can be reduced.

Also, since at least the surface of the panel is made of fiber reinforced resin (FRP) or aluminum, a guide member having an engaging hole through which a bar of the auxiliary form panel can be inserted is fixed to the back surface of the panel. Since the crosspiece of the auxiliary form panel can be inserted into the engagement hole and assembled integrally, there is an effect that an irregular form panel of an arbitrary length (height) can be easily manufactured.

Further, the above configuration has the effect of increasing the durability of the form panel and providing a form panel capable of withstanding tens of diversions. Can be greatly reduced, the size of the material storage area can be reduced, and the construction cost can be reduced.
