[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roofing material formed by integrally molding a plurality of roofing sheets and having improved handleability and transportability.

[0002]

2. Description of the Related Art As shown in FIG. 5, for example, a roofing material 02 made by laminating two roof members 01A and 01B such as roof tiles and integrally forming the same is constructed by laying two sheets in one construction. It has been proposed to improve workability.

[0003]

However, as shown in FIG. 6, when a plurality of conventional roof members 02 formed by integrally forming two roof members 01A and 01B are stacked, as shown in FIG. There is a problem because it gradually shifts.

Accordingly, as shown in FIG. 7A, the bottom surface of the upper roof member 01A constituting the roof material 02 is thickened and the rear surface side 02a is flattened, so that the roof material 02 is alternately formed.
Although competitors can be stacked facing each other, there is a problem that the roofing material itself becomes heavy, the workability is reduced, and the cost is increased.

[0005]

The roof material according to the present invention which solves the above-mentioned problem has a hydraulic property which is obtained by integrally molding adjacent substantially rectangular roof members in a state of being superposed stepwise. a roofing material comprising a roofing material body made of inorganic composition, in any of the roof element, on the back side of the roof member
Its projecting in the thickness direction has a projection portion that is embedded integrally in the molding of the roofing material body, and the co becomes provided with a draining thin plates of the different material than the roof member, the back surface side flat flush against It is characterized by being made into.

[0006]

In the above-mentioned construction, since a draining thin plate made of a material different from that of the roof member is provided and the adjacent roof members are overlapped with each other, the entire roof material can be made thinner, and the front surface and the back surface can be separated. Even if a plurality of roofing materials are stacked facing each other, it is light and compact.

[0007]

Embodiments of the present invention will be described below.

FIG. 1 is an explanatory view of a roofing material according to the present embodiment, in which (A) is a plan view, (B) is a front view, and (C).
Is a side view thereof. As shown in FIG.
The upper roof member 11A and the lower roof member 11B
Are integrally formed in a step-like manner to form the roofing material main body 12, and a drainer thin plate 13 is integrally provided on a side surface portion of the roofing material main body 12. In the drawing, reference numeral 14 denotes a groove provided on the surface.

As shown in FIG. 2, the draining member provided on the side surface of the roofing material main body 12 is a roof member 11 on the upper side.
In the case of A, a draining portion 13A integrally formed of a hydraulic inorganic material may be used, and only the draining portion 13B provided on the lower roof member 11B may be a draining thin plate 13B made of a different material.

In the present invention, the roof material body 12 is generally made of cement or the like, and various other ceramic materials such as siliceous materials, calcareous materials, reinforcing fibers, aggregates, water reducing agents, thickeners and the like. Hydraulic inorganic composition appropriately blended according to the purpose,
Materials preformed or kneaded by papermaking, extrusion, semi-dry molding, etc. (hereinafter referred to as "kneaded material")
Is directly molded by pressure using a molding die and cured by curing.

The draining thin plate 13 is, for example, as shown in FIG.
(A), unsuitable (B), the (C), the above kneaded product tabular and the thickness direction of the roofing material body 12 (D direction)
The draining thin plate 13 has an engaging projection 17 formed on the flat plate 16 of the draining thin plate 13 along the direction in which the projection 15 stands.

The draining thin plate 13 is made of a metal or a synthetic resin and is formed by integral molding. When the roofing main body is manufactured, the draining thin plate 13 and the roofing main body 12 are interposed via the projections 15. And are integrally molded. Note that the draining thin plate 13 is not limited to being provided integrally with the side end portion of the roofing material main body 12 as shown in FIG. 1, and may be located at any one of the outer peripheral portions of the roofing material main body 12 as necessary. Is fine.

In the roofing material 10 of the present embodiment, the draining thin plate 13 made of a material different from the material of the roofing material main body is used in at least a part of the draining portion, so that the total thickness of the roofing material 10 can be reduced. .

As a result, as shown in FIG. 4, even if a plurality of sheets are stacked with the front and back surfaces of the roofing material facing each other, the roofing material is lighter and more compact than before.

Specifically, in the case of a roofing material of 450 mm × 600 mm, the thickness of the roof member on the upper side is about 40 mm and the weight is about 10 kg, which is considerably heavy in the related art as shown in FIG. In this embodiment, the thickness of the upper roof member is 18 to 20 mm, and the thickness of the lower roof member is 9 mm.
The compact size was about mm and the weight was light, about 4 to 5 kg. Even when 4 to 6 sheets were stacked, the size became compact, and there was no problem in transportability and handling.

[0016]

[Effects of the Invention] As described above, the roofing material of the present invention is made thinner by using a draining thin plate made of a different material for at least a part of the draining portion, so that the roofing material is lightweight and can be loaded in a large number of sheets. As a result, it was possible to improve the transportability and handleability as compared with the conventional case.
