ている。2. Description of the Related Art Heretofore, in an apparatus for forming a concrete plate (also called a PC panel) by surrounding a pouring board with a mold and pouring a concrete into the inside of the pouring board, the form is poured into the form. Various devices (clamps) for supporting and fixing to a base plate are provided. Usually the device is, for example,
A metal curved plate having a bolt hole in the center, with its concave surface facing down, insert the fastening bolts from above the metal curved plate into female screw holes provided at intervals along the mold on the pouring platform side. Then, the horizontal base plate and the pouring base plate are bridged and held down at the lower ends of both ends of the metal curved plate, and the fixing bolts are tightened and fixed.

間と手間を要する難点があった。In this device, a bolt is inserted into a bolt hole provided in the center of a metal curved plate, and a fastening bolt is screwed into a female screw hole provided in a pouring board and tightened and fixed with a tool such as a spanner. Things. The work was performed for each of those places, and it took a lot of time to fix all of the many places, and the work efficiency was very poor. Furthermore, if the poured concrete intrudes into the female screw hole, the concrete solidifies and sticks in the female screw as it is, and there is a possibility that the fastening bolt cannot be securely screwed. Also, when removing the formwork, the removal work performed for each location has a drawback that requires much time and labor as in the case of the fixing.

A device that inserts a fixing bolt into a U-shape with a U-shaped fitting in between, presses the horizontal base plate of the mold with the lower surface of the U-shaped fitting on the pouring board, and tightens and fixes the fixing bolt. Is provided.

It took a lot of time to work and the work efficiency was very poor. In addition, there is the same problem as in the above-described apparatus in that the concrete is solidified in the female screw and sticks and the trouble of the work of removing the concrete.

It was only to pinch the mold, and there was no function to stretch the side of the form even if it was diverted to the form as it was, and it could not cope with securely supporting and fixing the form.

合と同様であった。As another example of the device, there is provided a device in which a turnbuckle is incorporated in the middle of a strut support rod. In this type of apparatus, the support rods arranged at intervals along the formwork are supported and fixed by simply turning the support rod toward the side of the formwork by turning a turnbuckle. There was a drawback that the horizontal base plate portion of the mold could not be held down. For this reason, when the concrete is poured, the slurry is strongly displaced from the inside to the side surface of the mold, causing the mold to be displaced or tilted, and there is a problem that the accurate position cannot be stably maintained. Also, in this apparatus, the turnbuckle must be turned for each location to perform the tensioning work and the work of removing the same, and the point that much time and labor is required is the same as in the case of each of the above-mentioned apparatuses.

The part and the bottom part are pressed against the outer surface 1b of the mold 1 and the right-angled intersection of the horizontal base plate 1a. Then, the height adjustment bolt 16 on the rear portion 5b of the clamp slider 5 is turned to adjust the vertical movement of the clamp slider 5 so that the intermediate portion 5c of the inclined clamp slider 5 is finely adjusted to a horizontal state.

Thereafter, when the concrete has dried and solidified, the handle 12 of the cam clamp shaft 9 is operated with one touch to release the tightening of the pressing cam 13. Then, the clamp slider 5, which has been loosened from the cam clamp shaft 9 after the tightening is released, is retracted, and is further rotated sideways by about 90 degrees to be largely separated. And
When the mold 1 from which the clamp slider 5 has been removed is released, a concrete plate material A is obtained. In such a series of concrete plate material manufacturing steps, as described above, the work of fixing and removing the formwork 1 from the pouring board 2 can be performed without using a tool such as a spanner or a wrench.

るようになった。As described above, the present invention has been described above. Until now, the work of fixing and removing the formwork from the pouring board has to be performed by using a tool such as a spanner, one by one, taking time and effort, and tightening bolts. However, according to the present invention, these operations can be performed simply, reliably and extremely efficiently with one touch.

The operation of the conventional device requires about one minute per one place, and in the present invention, once the clamp slider 5 is mounted on the screw fixing part 3, it can be fixed in a few seconds thereafter. Therefore, the working efficiency is 20 to 30 in comparison with the conventional device.
It is twice as efficient.

った。The finishing accuracy of the concrete plate product is also fixed by pressing the bottom of the contact plate 6 below the horizontal base plate 1a and pressing the front surface against the outer surface 1b of the formwork 1. The support is the height adjustment bolt 16
In combination with the horizontal adjustment of the clamp slider 5, it is possible to withstand the strong pressure of the poured concrete slurry, and there is no displacement of the mold 1. It has become possible to easily manufacture high quality concrete plate products having extremely high dimensional accuracy.
