Description

[Detailed description of the invention] As a tile fixing method in the tile tip driving method, there is a joint square method in which tiles are fitted and aligned in the squares of a tile fixing square body layered on the back of the formwork. Generally, rubber squares and styrene squares are used as tiles for fixing tiles in this method, but since rubber squares are expensive,
If it can be reused nine times or more, it will be profitable, but
For low-rise buildings or buildings that cannot be converted to other uses, styrene boxes are economically advantageous.

However, with polystyrene square bodies, there is still no way to securely fix the tiles to the formwork, so problems such as tiles falling off, misalignment, distortion, and poor alignment occur during and after construction. There is.

This project was proposed in order to solve such problems.The tiles are arranged and fitted into squares divided vertically and horizontally in a polystyrene square body for fixing tiles layered on the back of the formwork. A wire mesh is layered on the back surface of the wire mesh, and a groove-shaped fastening piece is disposed on the back surface of the wire mesh across the striations of the wire mesh, and is fitted into the joint between adjacent tiles and the through hole of the square body. A tile characterized in that an end separator is inserted through the rubber seat piece and the through hole of the formwork, and a formwork tightening rod is screwed and tightened to the protruding end of the formwork of the separator. This relates to a tile fixing device in the pre-driving method.

According to the present invention, as described above, the tiles are arranged in predetermined positions by fitting the tiles into the vertically and horizontally divided squares of the styrene square for fixing the tiles layered on the back of the formwork. be done.

Then, a wire mesh is layered on the back of the same tile, and a groove-shaped fastening piece is arranged on the back of the wire mesh so as to straddle the lines of the wire mesh, and the fastening piece and the joint part of the adjacent tile are arranged. An end separator is inserted between the rubber seat piece fitted into the through hole provided in the square body and the through hole of the formwork, and a formwork tightening rod is inserted into the part of the separator that protrudes from the formwork. Since the screws are tightened, the tiles are securely fixed to the formwork through the wire mesh and the styrene square body for fixing the tiles, and there will be no peeling, distortion, or poor alignment of the tiles during construction, and the concrete can be poured. In this case, the same methods as usual, such as pounding and using a vibrator, can be used without worrying about tiles falling off, warping, or malalignment, so that high-quality concrete is poured, and after demolding, it is easy to clean. Concrete is placed with high reliability with fewer problems, and joints are not easily clogged.Compared to conventional methods, less repairs are required after tile placement is completed, which can save construction costs and construction time. It is.

In addition, since a rubber seat piece is fitted into the through hole into which the end separator of the square body is to be inserted, there is a risk that the tile will split when the wire mesh is crimped to the back of the tile as described above. Without,
Also, since it has good releasability to concrete, it can be used for other purposes.

The present invention will be described below with reference to illustrated embodiments.

1 is a plywood formwork, on the back of which a styrene square body 2 for fixing tiles is stuck, tiles 3 are fitted and arranged in the squares, and the back side of the tiles 3 is treated with anti-corrosion treatment. Wire mesh 4 is layered.

The formwork 1 and the styrene square body 2 for fixing the tiles are pre-drilled with through holes 1a and 2a communicating with the tile joints at predetermined locations, and the through holes 2a are filled with rubber catch pieces 5 and 2a. A hexagonal washer 6 is fitted.

As shown in FIGS. 5 and 6, the seat piece 5 has a truncated conical protrusion 5b integrally projecting from a disc-shaped base 5a, and a through hole 5c is bored in the center. The protruding portions 5b fit into the joints of the tiles 3. Since the seat piece 5 is made of rubber, it has appropriate elasticity, so there is no risk of the tile splitting when the wire mesh is crimped to the back of the tile as described later, and it has good peelability against concrete. , diversion becomes possible.

Reference numeral 7 indicates a groove-shaped tightening piece disposed on the back side of the tile 3 so as to straddle the lines of the wire mesh 4; 8 indicates the through-hole 1a of the formwork 1, the central through-hole 5a of the seat piece 5, and the tile. The end separator is inserted through the joint part 3, and the inner end thread part 8a is connected to the tightening piece 7.
It passes through the through hole 7a and is screwed onto a joint nut 9 that is in contact with the back surface of the tightening piece 7, and is connected to a separator 10 in the center that is screwed onto the joint nut 9. On the other hand, the outer end thread part 8b of the separator 8 is threaded into the thread hole of the hexagonal washer 6, and the formwork tightening rod 11 is threadedly attached to the end protruding from the through hole 1a of the formwork 1. ing. In the figure, reference numeral 12 denotes a vinyl hose that is fitted into the joint of the tile 3 between the tightening piece 7 and the seat piece 5 so as to surround the separator 8, and protects the concrete from going around the outer periphery of the separator 8. It is something to do. In addition, 8c and 8d in the figure are the separators 8
The raised tightening pieces 7 and the stoppers 8e and 8f of the hexagonal washer 6 are the end back cut portion and center back cut portion of the separator 8, respectively, and the separator 8 is removed after concrete pouring and demolding. When separating the separator 8 with a tool, use the end back cut 8e.
is rotated to remove it from the joint nut 9. However, if the outer end thread part 8b is damaged, the center back cut part 8f is used.

Note that glue or glass putty is applied to the smooth surface portions and concave portions of the tile 3, respectively, to prevent cement slag from adhering.

Since the illustrated embodiment is configured as described above, as the formwork is tightened and assembled via the formwork clamping rod 11, the wire mesh 4 is pressed against the back surface of the tile 3 by the clamping piece 7. The tile 3 is firmly fixed to the formwork 1 via the square body 2. At this time, since the seat piece 5 that clamps the tile 3 together with the tightening piece 7 is made of rubber as described above, the tile 3
There is no need to worry about it splitting apart.

Since the tiles 3 are securely fixed to the formwork 1 in this way, the concrete structure A can be pounded and pounded without worrying about the tiles 3 falling off, distorted, or having poor alignment, which is different from ordinary concrete pouring using a vibrator. As a result, high-quality concrete with less jitter, etc. is poured, and the finish is good with good joint clogging, and it is easier to repair after tile placement is completed than with the conventional method. This allows for cost savings.
