Description

[Detailed description of the invention] When constructing a concrete structure, this invention arranges the exterior tiles in contact with the concrete pouring Q form, and after the poured concrete solidifies, the formwork is removed and the tile installation work is completed. This invention relates to a tile protection device designed to prevent exterior tiles from cracking and to shorten the working time of concrete structure construction in the so-called exterior tile pre-installation method.

Conventionally, in the pre-installation method of exterior tiles, it is necessary to correctly attach the exterior tiles to the predetermined position on the poured concrete via the formwork or a buffer between the formwork and the adhered material, and to connect the exterior tiles between the outer formwork. Various tile protection devices have been developed to escape and protect the tile from the tightening force of the tightening separator, but these devices are complicated and difficult to fall down.

Especially when pasting thick mail, great care has been taken to protect it.

Based on this knowledge, the present invention proposes a tile protection device designed to eliminate these drawbacks in the exterior tile pre-installation method in which thick tiles are pasted.

The following explanation will be given based on the drawings.As shown in Fig. 1, thick tiles 3 are interposed between the plywood formwork 1 and the poured concrete 2, and holes 4 are formed in the center of the tiles 3 at predetermined intervals. In addition to arranging the perforated tiles, the plywood formwork 1 that comes into contact with the tiles 3 having the shaped holes 4 is provided with the tiles 3.
A hole 5 having a smaller diameter than the hole 4 is bored in advance.

Next, holes 4 of the tile 3 and holes 5 of the plywood formwork 1 have holes 2 to 3.
Insert the shaft rod 6 having the shape shown in the figure.

Both shaft ends 7 and 8 of the shaft rod 6 are threaded and have the same diameter, and one of the shaft ends 7 has a hole 5 drilled in the plywood formwork 1 so that it can be inserted into the tile 3. An enlarged portion 9 is formed having a smaller diameter than the drilled hole 4, and its length H is slightly longer than the thickness R of the tile 3.

A neck portion 10 having a diameter smaller than that of the shaft end 8 and having a thickness equal to that of the plywood formwork 1 is formed between the other shaft end 8 and the enlarged portion 9 .

The shaft rod 6 thus formed is inserted into the holes 4 and 5 drilled in the tile 3 and the plywood form 1, respectively, so that the shaft ends 8 are exposed outside the plywood form 1.

Since the diameter of the expanded portion 9 of the inserted shaft rod 6 is larger than the diameter of the hole 5 of the plywood formwork 1, the end face of the expanded portion 9 and the formwork 1
are inserted into the hole 5 while being prevented from coming into contact with each other.

Since the length H of the enlarged portion 9 is slightly longer than the thickness H' of the tile 3 as described above, the enlarged portion 9 on the shaft end 7 side
The end portion of the tile 3 is inserted into the hole 4 of the tile 3 so as to slightly protrude from the hole 4.

Next, an appropriate tightening device is screwed onto the shaft end 8 side of the shaft rod 6 inserted into the hole 5 of the plywood formwork 1 and the hole 4 of the tile 3 in this way, and the other shaft end 7 A packing material 11 made of rubber or the like as shown in FIGS. 4 and 5 is fitted into the side of the tile 3 in contact with the tile 3, and the packing material 11 is made of a diameter larger than the hole 4 of the tile 3 so that the packing material 11 is tightly attached to the surface of the tile 3. A joint nut 13 having a collar 12 is screwed together.

A separator 14 that connects and tightens the inner and outer formwork is screwed into the joint nut 13.

Now, even if the joint nut 13 is screwed onto one shaft end 7 side of the shaft rod 6, the joint nut 13 is connected to the collar 12 and the hole 4 of the tile 3, that is, the hole 4 of the tile 3. Since the protruding end portions come into contact with each other and the tightening pressure does not spread to the periphery of the hole in the tile 3, the tile 3 is not cracked or cracked at all.

In addition, since the flange 12 allows the packing material 11 inserted into the small gap between the tile 3 and the tile 3 to be brought into close contact with the circumferential side of the hole 4 of the tile 3, cement will not flow into the hole 4 even when concrete is poured. 9. After the poured concrete 2 has solidified in this way, the tightening tool screwing and fitting the outer plywood form 1 and the shaft rod 6 is removed, the plywood form 1 is removed, and then the poured concrete 2
The shaft rod 6 screwed with the joint nut 12 buried therein is pulled out, and mortar is injected into the hole 4 of the tile 3 after this pulling out to repair the joint.

As described above, with the device of the present invention, thick tiles, which were difficult to apply using the pre-applied method for exterior tiles, can be pasted with a simple device, without damaging the tiles, and joint repair can be done easily and quickly. It has excellent advantages.
