Description

DETAILED DESCRIPTION OF THE INVENTION The present invention forms a large number of recesses on one surface of a resin sheet, and fits into these recesses with the tile surface facing the sheet side to form a tile unit. The unit is pasted on the side of the concrete pouring formwork corresponding to the concrete pouring side with the tiles facing the concrete pouring side, concrete is then placed, and the formwork is dismantled and the above-mentioned This invention relates to a tile-based recycling method that includes a step of creating a tile wall using a tile tip method in which a tiled concrete wall is obtained by peeling off a sheet.

Conventionally, the tile tipping method has been used, for example, in the
A method as described in Japanese Patent No. 19016 has been proposed.

This method has many advantages as described in the same bulletin, and it allows tiles to be attached to the existing concrete wall by applying mortar, adhesive, etc. and pressing the tiles. Although this method is far superior to other methods, in order to fit and hold the tiles into the recesses of the sheet, adhesive was applied to the tile surface and attached to the sheet, so when the sheet was peeled off, There is a disadvantage that adhesive remains on the tile surface and the sheet, making the tile surface dirty, and it is difficult to reuse the sheet because of the residual adhesive, and adhesive must be applied to each tile one by one. Therefore, it is difficult to expect a significant improvement in work efficiency.

Furthermore, due to the manufacturing method and the materials used, tiles vary widely in their dimensions. Therefore, when inserted into a recess, the space between the rising wall surface of the protruding strip that forms the recess and the tile circumferential surface is large. Therefore, if concrete is poured with the concrete covered, the concrete will enter the gap and after hardening, a step will be formed in the wall depth direction at the joint, creating a beautiful appearance. It is difficult to form joints and requires post-processing, and in this respect, it is difficult to expect efficient work.

Therefore, the present invention was devised as an improvement in view of the shortcomings of the conventional methods. Even if the tiles have uneven dimensions, this variation can be absorbed well, and the finish of the first concrete joint can be improved by finishing the first joint with concrete. Compared to conventional methods, it is possible to create a beautiful tile with no individuality, and there is no residual adhesive on the tile surface, resulting in a beautiful tile surface.In addition, it is expected to improve work efficiency and reduce construction costs. The present invention aims to provide a tile-based recycling method that includes a tile wall manufacturing process using the tile tipping method.

fi'lJ, the present invention forms a large number of squares by integrally molding convex stripes vertically and horizontally on the surface of a base made of thermoplastic resin with dimensions slightly larger than the vertical and horizontal dimensions of the tile. Then, a tile is inserted into each of these squares with its surface facing the base side, and then the base is heated to a state where the ridges melt and flow, thereby filling the gaps on the tile circumferential surface. At the same time, the base is melt-bonded to the circumferential side of the tile, or to the circumferential side and the tile surface to form a tile unit, and after this tile unit is attached and fixed to the inner surface of the concrete form, concrete is poured, Thereafter, the base is peeled off at the same time as the mold is dismantled, and the peeled bases are collected and melted, and the molten resin is reused as a base molding material.

In other words, since the peeled base has already been deformed by melting, it is difficult to melt and bond another tile to the peeled base as expected.
Therefore, this peeled base is often considered to be disposable.

However, when this method is applied to attach decorative tiles to the exterior walls of high-rise buildings, for example, the number of peeled base tiles becomes extremely large, making it difficult and difficult to dispose of or incinerate them. At the same time, it requires a huge amount of money, and it also poses serious problems such as causing pollution.

According to the present invention, the peeled base has no adhesive remaining on it, making the most effective use of the thermoplastic property of the base, and as described above, there is no adhesive remaining on the base. Since the base after peeling can be transported to a tile unit manufacturing factory, where they are collectively melted and reused as a base molding material, the above-mentioned disposal and incineration processes are not required at all, but no pollution is generated. This made it possible to reduce the cost of the tile unit itself through the circular reuse of materials, and to significantly reduce construction costs overall.In particular, the base could be made in the same shape using the same manufacturing process. It has become possible to repeat the process, making it easier to fit into the squares of the tile compared to using the tile that has been molded and used as is, and also has the disadvantage of not being able to absorb dimensional errors in the tile. It has come to disappear.

Furthermore, by heating the base to a state where the convex stripes melt and flow, the gap on the tile circumferential surface is filled. At the same time, the base is melted on the circumferential side of the tile, or on this circumferential side and the tile surface. Because it is glued,
No steps are formed in the wall depth direction at the joints, and therefore the first-shot joints with Concrete 1 can be finished in a beautiful condition that is comparable to the later joints.The soil adheres to the tile surface. There is no disadvantage of residual adhesion of the quill, and the work of inserting tiles into the squares is easy because no adhesive is used, and since the adhesive on the surface of the quill is adhered, no post-treatment is required. As a result, we were able to improve our work efficiency.

Hereinafter, embodiments of the present invention will be described step by step based on the drawings.

(1) Made of thermoplastic resin such as polyvinyl chloride, polyethylene, polystyrene, styrene-acrylonitrile-butadiene copolymer, etc., in a state in which convex strips 2 are integrally formed vertically and horizontally on one side, and the other side is flat. Form the base 1.

The tile 4......flows between the surrounding side surface and is integrally bonded to this circumferential side surface, and the entire circumferential side surface of each tile 4 is held under pressure by the side surface of the convex strip body 2 that has been melted and then hardened. At the same time, the upper surface of the base 1 is also heated and melted, and the surface of each tile 4 is integrally bonded to this, resulting in a large number of tiles 4...
A tile unit 5 is manufactured in which the... are fixedly held on the base 1.

Adhesive strength can be easily adjusted by adjusting the amount of heating.

(6) When the concrete hardens to a predetermined hardness, the tiles 4 are strongly bonded and held to the concrete.

At this stage, the formwork 7 is dismantled and the base 1 is peeled off from the tiles 4 bonded to the concrete.

(Force) A large number of base stones were peeled off in this way...

When transporting the tile unit 5 or installing it on the formwork 7, or during concrete pouring or pre-watering, etc., each tile 4... is attached to the base 1 on its surface and all sides. Since the tiles are strongly bonded and held, it is reliably prevented from accidentally peeling off or intruding concrete slag between the base 1 and the tile 4 surface.

Incidentally, the convex stripes 2 may be arranged in a vertical and horizontal grid pattern (checkerboard pattern).
