Abstract

PURPOSE:To improve productivity, and to reduce cost largely by extrusion- molding a long-sized roof tile raw material having an L-shaped cross section. CONSTITUTION:A long-sized roof tile 1 having an L-shaped cross section is extrusion-molded, and cured and dried, and the roof tile raw material 1 is cut in fixed length. A creasing groove 4 is machined to the lateral piece 3 of the cut intermediate 2 having the L-shaped cross section. The lateral piece 3 and a longitudinal piece 5 are cut so that width is narrowed toward the ridge side and height is lowered toward the ridge side in the lateral piece 3 and longitudinal piece 5 of the cut intermediate 2, thus manufacturing a verge roof tile.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing glazed roof tiles, and more particularly to a technique for increasing productivity.

[0002]

2. Description of the Related Art Conventionally, the height of the vertical piece of the glazed roof tile having an L-shaped section is lower toward the ridge side, and a draining groove is formed on the ridge side portion of the horizontal piece. Is a vertical piece.

[0003]

However, in the case of such a structure, it is a single-piece production, its productivity is low, and the cost is high as a gallant accessory. Cannot be extruded and
There is a problem that it is difficult to increase the height of the vertical piece appearing in the shingle, and it is impossible to give the vertical piece a degree of freedom because the mold is formed one by one.

The present invention has been made in view of the above problems, and an object thereof is to extrude a long tile raw material having an L-shaped cross section and separately form a groove on a cutting intermediate product. By doing so, it is possible to increase the overall productivity, significantly reduce the cost, allow the vertical pieces to have a high degree of freedom, and to improve the appearance. There is to try to serve.

[0005]

The present invention is a method for manufacturing a glazed roof tile having an L-shaped cross section, in which a long tile base material 1 having an L-shaped cross section is extruded and cured and dried after being cured. The material 1 is cut into a certain length, the horizontal piece 3 of the cutting intermediate product 2 having an L-shaped cross section is processed into the draining groove 4, and the vertical piece 5 is formed so that the height becomes lower toward the ridge. It is characterized by cutting.

[0006]

In this way, the long tile raw material 1 having an L-shaped cross section is extruded, and after curing and drying, the tile raw material 1 is cut into a certain length, and the cut intermediate product 2 having an L-shaped cross section is laterally cut. By processing the draining groove 4 in the piece 3 and cutting the vertical piece 5 into the vertical piece 5 so that the height becomes lower toward the ridge side, the long roof tile material 1 having an L-shaped cross section is extruded. , Curing and drying this tile raw material 1,
After that, it is cut into an appropriate length, the draining groove 4 of the horizontal piece 3 is processed, and the vertical piece 5 is cut into the vertical piece 5 so that the height becomes lower toward the ridge. Yes, it is possible to increase the productivity by using extrusion molding as compared with the conventional one-piece production, significantly reduce the cost, and to give the vertical piece 5 a high degree of freedom. is there.

[0007]

Embodiments of the present invention will be described in detail below with reference to the drawings. The glazed roof tile A having an L-shaped cross section is formed by extrusion-molding a long tile raw material 1 having an L-shaped cross section by using a cement-based material in which fibers are appropriately mixed to increase crack strength. Such tile raw material 1 is cured and dried in an autoclave, and then the tile raw material 1 is cut into a certain length to obtain such a cross section L.
The horizontal piece 3 of the character-shaped cutting intermediate product 2 is processed into the draining groove 4, and the width of the horizontal piece 3 and the vertical piece 5 becomes smaller toward the ridge side, and the height becomes lower toward the ridge side. In this way, the horizontal piece 3 and the vertical piece 5 are cut to manufacture the glazed roof tile A.

Thus, the roof tile material 1 having an L-shaped cross section and a long length
Is extruded, the roof tile material 1 is cured and dried, and then cut into appropriate lengths, the draining groove 4 of the horizontal piece 3 is processed, and the horizontal piece 3 and the vertical piece 5 are cut. ,
Keraba roof tiles are manufactured by using extrusion molding as compared with conventional single-piece production to improve productivity, significantly reduce costs, and allow vertical pieces 5 to have a degree of freedom. Is. In the figure, 6 is a through hole for nail driving.

[0009]

As described above, according to the present invention, a long tile raw material having an L-shaped cross section is extrusion-molded, and after curing and drying, the tile raw material is cut into a certain length, and an intermediate cutting of the L-shaped cross section is performed. Since the horizontal piece of the product is processed into a draining groove and the vertical piece is cut into the vertical piece so that the height becomes lower toward the ridge, a long roof tile raw material with an L-shaped cross section is extruded. After curing and drying the raw material, cut it to an appropriate length, process the draining groove on the horizontal piece, and cut the vertical piece so that the height becomes lower toward the ridge side Since it can be manufactured, the productivity can be improved by using extrusion molding as compared to the conventional single product production, the cost can be significantly reduced, and the height of the vertical piece is also free. There is an advantage that it can have.
