Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention is a device for preventing a large tile from falling off concrete.

[0002]

2. Description of the Related Art Up until now, medium-sized and small-sized tiles have been used, but recently, large-sized tiles are often built in a PC board and crowded. In that case, consideration for preventing the tile from falling off the concrete becomes a problem.

[0003]

If the tile becomes large-sized, it will easily fall off from the concrete if the back surface of the tile is smooth unless the adhesive strength with the concrete is increased.

[0004]

In consideration of such a point, the present inventor has made various experiments and trial productions, and as a result, in the present invention, the large tiles are each divided into two areas at several positions on the back surface thereof. While grooving each groove, use a special metal fitting that has a pair of tip legs that are inserted along these grooves, connects these legs, and fits them with a curved part at the center upper part. It is intended to increase the adhesion strength between concrete and tile by placing.

[0005]

Thus, in the device of the present invention, a large number of special metal fittings 3 having a pair of tip legs 3a and having a curved portion 3b at the center of the piece connecting the legs 3a are integrally used as needed to make a large tile. The purpose of the present invention is to increase the adhesive strength when concrete is placed by combining the two grooves 2 provided in advance on the periphery of the back surface of No. 1.

[0006]

1 is a perspective view of a special metal fitting 3 used in the device of the present invention. Reference numeral 3a denotes a pair of distal legs, and a curved portion 3 for providing flexibility in the upper center of a piece connecting the legs 3a.
b. The width actually used for both legs is 35
A gruel, a bracket width of 15 and a height of about 30 is used. FIG. 2 shows a large-sized tile used in combination with the special metal fitting 3, where 1 is a large-sized tile, which is actually about 600 grits, and an appropriate number of grooves 2 are provided on the peripheral edge of the back surface. Next, the two tip legs 3a of a special metal fitting 3 such as stainless steel, which is separately provided, are fitted into these grooves 2 and mounted, and then epoxy adhesive is filled and fixed in these grooves 2 and then concrete is poured, The adhesion-enhancing strength of the concrete concrete is secured, and the concrete is prevented from falling off.

Also, a PC (precast concrete) board
Large tiles often break while being cast on large tiles. In such a case, this special metal fitting 3 is used for repair . It ’s a precast
In some cases, it may be necessary to remove the cracked tiles after hitting the cleats .
Chisel the iles into the groove 2 on this tile as shown in Figure 3.
While fitting the leg tips 3a, 3a of the special metal fitting 3,
The center of the special metal fitting 3 that connects the ends 3a, 3a has a spring property.
If you give it a curved portion 3b, the tip of this special metal fitting 3
3a and 3a bite into the groove 2 while penetrating the PC board panel
Drill stainless steel wire 5 and drill stainless steel wire 5
Of the special metal fitting 3 has one end on the curved portion 3b and the other end is made of stainless steel.
Connect them to the tenless pins 6 of the countersink hole 7 for pinning,
After that, apply polymer cement mortar filling and firmly
It will be fixed.

The tiles are chipped in the chisel The notches around the tiles are cut with a diamond cutter, the surrounding tiles are cured with a plywood board, and the tiles are chipped using a chiseling machine.

[0009]

As described above, according to the present invention, while a large number of two grooves 2 are formed on the rear surface of the large tile, a pair of leg tips 3a are inserted along the grooves 2, respectively. By connecting the equal leg tip portions 3a and combining the special metal fitting 3 having the curved portion 3b in the central upper portion, it is possible to increase the adhesion strength when placing concrete and large tiles, and further to place large tiles into concrete. It is convenient for later repairs.
