Abstract

PURPOSE:To be not required the finishing work, and improve the tile pre- attachment to render an accuracy of product to be excellent by fitting a tile in a recessed part formed into a tapered shape wherein the distance of the faced side walls becomes large gradually as they go down the bottom part thereof in the bottom plate of a mold frame consisting of an elastic material, and curing it in flowing a curing material into the mold frame. CONSTITUTION:A tile 4 is fitted in the recessed part 2 of a bottom plate 1. The tile 4 is fitted in such a manner that the face to be exposed on the surface of a building is faced downward, and the rear surface thereof is faced upward. Since the side wall 3 of the recessed part 2 is formed into a tapered shape, and has an elasticity, the tile 4 is held therebetween even it has a little dimensional error, and thus, any gaps never occur between it and the tile 4. And, a curing material 5 such as mortar or concrete is flown into the bottom plate 1 in order to cure it. The tile 4 is buried into the curing material 5 in its part projecting out of the bottom plate 1, and integrated with the curing material 5 cured therein, thereby completing a tile pre-attached precast board.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of manufacturing a precast tile plate used as an exterior wall of a building.

[Prior Art] Precast plates have been developed in which tiles used as exterior walls of buildings are pre-attached in a factory. To embed tiles on one surface of a precast plate, recesses are formed in the bottom plate of the formwork, tiles are fitted into each recess, and mortar or concrete hardening material is filled on top of the recesses and hardened. It is.

[Problems to be solved by this invention]

A problem with this manufacturing method is that the tile dimensions have an error of 2 to 3 mm. In other words, if the recess formed in the bottom Fia of the form is simply a U-shaped recess as shown in Fig. 4, a gap will be created between the tile C and the side wall of the recess. The hardening material gets into the gap and it is necessary to remove that part after demolding. Moreover, the tile C becomes misaligned within the recess, resulting in poor product accuracy.

This invention was made in order to solve the above-mentioned problems, and its purpose is to provide a method for manufacturing a precast tile plate that does not require finishing work and improves the precision of the manufactured product. do.

[Means to solve the problem]

The method of manufacturing a precast tile tip plate according to the present invention uses a bottom plate of a form made of an elastic material. The openings of the four recessed portions of the bottom plate have the same shape as the tiles, and the side walls thereof are tapered so that the distance between them and the opposing side walls gradually increases toward the bottom. A tile is fitted into this recess and sandwiched by the elasticity of the side walls. In this state, a hardening material is poured into the mold and hardened.

The concave portion of the bottom plate described above may be formed into a tapered shape around the entire circumference, or, for example, only two sides of the rectangular concave portion may be formed into a tapered shape.

The aforementioned bottom plate may be formed of a rubber-based material.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in the drawings.

In the figure, reference numeral 1 denotes the bottom plate of the formwork, which is made of synthetic rubber. A plurality of recesses 2 are provided at appropriate positions on the surface of the bottom plate 1. The opening of the recess 2 has the same shape as the tile 4 to which it fits, but its side wall 3 is formed in a tapered shape.

That is, the side walls 3 are formed so that the distance between them and the opposing side walls 3 gradually increases as the distance from the side walls 3 approaches the bottom. In the embodiment shown in FIG. 3, all four sides of the rectangular recess are tapered.

The depth of the quadrant 2 is smaller than the thickness of the tile 4.

The tiles 4 are fitted into the recesses 2 of the bottom plate 1 as described above. The tile 4 is fitted into the recess 2 with the surface exposed on the front surface of the building facing down and the back surface facing up. The side wall 3 of the recess 2 is tapered and has elasticity, so the tile 4
Even if there is some error in the tile 4, the tile 4 can be inserted without creating a gap between the tile 4 and the tile 4.

In the above state, a hardening material 5 of mortar or concrete is poured onto the bottom plate l and hardened.

The portion of the tile 4 that protrudes from the bottom plate 1 is buried in the hardening material 5, and is integrated with the hardened material 5 to complete a tile tip plate.

In addition to the above embodiments, the present invention has various embodiments, and the side wall 3 of the recess 2 of the bottom plate 1 may be partially tapered instead of having the entire circumference tapered. For example, in the case of the four parts 2 having a rectangular shape, only the side walls on two adjacent sides may be tapered.

〔Effect of the invention〕

This invention has the above-mentioned configuration, and since a recess with tapered side walls is provided in the bottom plate of the formwork made of an elastic material, the tiles can be fitted into the recess so as to sandwich the tiles between the side walls. It is possible to absorb tile errors and close the gap between the side wall and the tile. Therefore, the hardening material adheres to the periphery of the tile, eliminating the need for finishing treatments such as peeling off. In addition, the position of the tiles will not shift, and the precision of the precast version will not be compromised.
