Description

[Detailed Description of the Invention] The present invention relates to a panel plate holding device for forming concrete columns that makes it possible to easily manufacture concrete columns. It is as follows.

This product consists of four panel holding rods 1, four bolt rods 4, four nuts 2, and four pins 10.

The panel holding rod 1 has a rectangular vibro having a bottle hole 5 drilled near the end thereof and a round pipe 7 intersecting in an L shape 3.

The bolt rod 4 has a male screw part 8 at one end, a square stop part 9 having a bottle hole 5' inserted into the square vibro at the opposite end, and is inserted into the round pipe 7. be.

The nut 2 has bundles 11 protruding from the left and right sides.

In the figure, reference numeral 12 is a panel plate, and 13 is a panel support protrusion.

To form a conventional concrete column, a foundation is formed, four panel boards are erected on top of it to form a vertical rectangular parallelepiped space, and reinforcing bars are placed within this space. The panels are filled with concrete, but since the four erected panel boards tend to expand outward due to the pressure of the filled concrete, holding frames must be attached at appropriate intervals to prevent this. The construction work of this holding frame was extremely troublesome as the pipes were arranged and fixed around the frame.

The present invention solves this drawback, and since it is configured as described above, the four panel presser rods 1 are arranged one after another in a square shape, are brought into contact with the panel plate 12, and are inserted into the respective round pipes 7. Insert the corner stop 9 of the bolt rod 4 into the square vibro of the adjacent panel presser rod 1, insert the pin 10 into the pin hole 5, 5' to connect and fix the adjacent panel presser rods 1, 1, and complete the round pipe. Bundle 1 is attached to male thread part 8 of bolt rod 4 protruding from 7.
When the nuts 2 with 1 are screwed in and tightened, the four panel boards 1
2 is securely held by the panel holding rod 1, and even if concrete is poured inside, the panel board 12 is reliably prevented from expanding outward, and a predetermined concrete column is formed.

In this way, the panel presser rod 1. Bolt rod 4. It is designed so that four nuts 2 and pins 10 are combined to form a rectangular frame, and it can be fixed by simply inserting the pin 10, and tightened by simply tightening the nut 2. One piece of the panel holding rod 1 is a square vibro, so it is securely connected to the corner stop 9 to prevent rotation, and its structure is simple and easy to operate, which eliminates the problem of conventional panel board fixing frames. The shape of the square frame can be changed to a square or rectangle depending on the screwing position of the upper nut 2, which makes the erection work easy and quick, and the size of the square or rectangle can be changed, which is extremely convenient and has an isotropic practicality. This is a panel holding device for forming concrete columns.
