Abstract

PURPOSE: To prevent even heavy, particular and cubic tiles from dropping out during handling and prevent the tiles from falling into disorder or shifting the position due to the deformation of a plastic sheet and efficiently and smoothly set the tiles. CONSTITUTION: A plastic sheet 4 is heated and closely stuck to the surface of tiles 2 arranged on a base frame 1 at every joint distance. Joint recesses 8 inserted in the joints are formed on the plastic sheet 4 and a back-up material 5 is charged in the clearance of the base frame 11 containing the joint recesses 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile construction form for attaching tiles to a concrete surface.

[0002]

2. Description of the Related Art Conventionally, a so-called tile pack, in which a large number of tiles are fitted and adhered to concave portions formed on one surface of a thermoplastic sheet at joint intervals, is attached to a concrete pouring formwork, and concrete is placed in the formwork. After pouring, the form is removed and the plastic sheet is peeled off to produce tiled concrete.
Known by the issue.

This method can be used for thin tiles that are light in weight, but in the case of heavy tiles with a unique three-dimensional shape and heavy weight, the tiles may fall off during handling or the plastic sheet may be deformed. Disturbances caused by this increase the labor of work and impair the aesthetics.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tile construction form that solves the above problems of the prior art.

[0005]

The above object can be achieved by the following means.

That is, according to the present invention, a plastic sheet is heated and brought into close contact with the surface of tiles arranged on the underframe at joint intervals so as to form a joint concave portion which penetrates into the joint, and the inside of the joint concave portion is included. To propose a tile construction formwork characterized in that the voids in the underframe are filled with a backup material, wherein the back-up material is sand,
Includes silicone, polyurethane, or FRP.

The present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view showing an embodiment of a tile construction form showing an example of the present invention.

According to the present invention, as shown in FIG. 1, a tile fitting recess 3 is formed on one side of a base frame 1 made of, for example, plywood and is appropriately divided by a joint wall 7, and the tile fitting recess 3 has tiles. 2 are fitted and tiles 2 are arranged on the underframe 1 with a joint interval.

On the surface of the underframe 1 and the tiles 2 on the underframe 1, a plastic sheet 4 coated with a known adhesive or adhesive on one side is heat-adhered so that the coated surface abuts,
A joint recess 8 is formed in the plastic sheet 4 so as to be inserted into the joint, and a backup material 5 is filled in a void in an underframe including the joint recess 8 and a lid 6 is attached. Reference numeral 12 is a hollow frame body that holds the peripheral edge of the plastic sheet 4 against the peripheral edge of the underframe 1 and that is placed on the underframe 1 and functions as an enclosure wall body, and is removable.

By covering the tile 2 and the like with the plastic sheet 4, the tile 2 for water when pouring concrete
It is possible to prevent wraparound to the surface. As the backup material 5, sand, silicon, polyurethane, FRP or the like is preferably used.

Examples of the plastic sheet 4 include EVA elastomer, polyethylene, polyvinyl chloride and the like.

The lid 6 and the frame 12 are made of the same material as that of the underframe 1.

FIG. 2 shows a plastic sheet 4 on a tile 2
FIG. 6 is a cross-sectional view showing a state of heating and closely contacting with the surface of.

The plastic sheet 4 is held by the clamp 42, and is heated and softened by the heater 41. When the clamp 42 is lowered, the plastic sheet 4 is removed from the suction hole 43 of the underframe 1 while covering the upper surface of the underframe 1. By being careful, the surface of the tile 2 and the joint wall 7 are brought into close contact with the entire surface.

Next, in order to manufacture a tiled concrete panel using the tile construction form of the present invention, the tile construction form prepared in advance is inverted as shown in FIG. So that the underframe 1 of is located on the upper surface side,
The underframe 1 is removed.

Next, as shown in FIG. 3, a well-known concrete formwork 9 having mounting bolt holes 10 and reinforcing bars 11 is set on the upper part of the tile construction formwork from which the underframe 1 has been removed, and concrete 13 is poured thereinto, and concrete 13 is poured. Let it harden.

Next, the structure shown in FIG. 3 is inverted, and the lid body 6, the frame body 12 and the plastic sheet 4 are peeled off,
By removing the concrete form 9, tiled concrete can be obtained.

The backup material 5 can be reused repeatedly.

[0020]

As described above, according to the present invention, a plastic sheet is heated and brought into close contact with the surface of tiles arranged on the underframe with the joint space therebetween, and the joint recess is formed in the plastic sheet to enter the joint. Since the voids in the underframe including the joint recesses are filled with the backup material, the tile construction form of the present invention can be inverted to set the concrete form directly on the upper opening of the tile construction form. For example, tiles can be installed, and even if the tile is heavy and has a unique three-dimensional shape, the tile will not fall off during handling. In addition, since the backup material is filled in the voids in the form, deformation of the plus sheet does not disturb the tiles or dislocate the tiles, and the time and effort of the work do not increase, so that efficient and smooth construction can be performed. Is.
