[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roofing material which is thin as a whole, has a high covering rate, and has an improved load resistance.

[0002]

2. Description of the Related Art Conventionally, as a roofing material, a material made of a clay-based material, a cement-based material, or a slate-based material reinforced with fibers has been used.

[0003] In general, a roofing material that is excellent in load-bearing capacity and good in raining is required. For example, a slate-based roofing material contains a reinforcing fiber or the like, so that a relatively thin and strong material can be obtained, which is good in terms of load-bearing capacity. , Roofing material 01
By overlaying comrades and covering the roof, rain is prevented from entering.

[0004] That is, as shown in FIG.
The lower part a is the roof material 0
In 1B, the infiltrated rainwater escapes to the roof surface, and the upper part b of the roof b prevents the infiltration of rainwater by the roofing material 01C located above. The upper end c of the roofing material 01A is covered with an upper roof 01C to prevent infiltration of rainwater.

[0005] As described above, the slate-based roofing material has a problem that about 60 to 70% of the roofing material overlaps as a covering portion, resulting in poor covering efficiency.

The present inventors have proposed a roof material having a thin roof material, a large covering efficiency, and good rain performance in order to solve the rain at the side end of the roof material. (Japanese Patent Application No. 4-196845).

FIG. 6 shows an example. As shown in FIG. 1, the roofing material 10 is composed of a roofing material main body 11 and a draining thin plate 12 integrally provided at a side end of the roofing material main body 11. In addition to the protrusion 13 standing upright in the thickness direction (D direction) of the roofing material main body 11, the flat portion 14 of the draining thin plate has a concave portion 16 provided at an end of one adjacent roofing material 10. The engagement ridge 1 extends in the direction in which the projection 13 is fitted.
5 are formed.

[0008]

[Problem to be Solved by the Invention] However, when constructing a flat roof that resolves rain and reduces the number of piles (that is, increases the covering rate), as shown in FIG. When it is placed on top of it, the thickness of the roofing material 10 is thin and the distance (L) of the support is long.

[0009]

Means for Solving the Problems The constitution of the roofing material according to the present invention, which solves the above-mentioned problems, comprises a kneaded material composed of a hydraulic inorganic composition or a kneaded material preformed in a flat plate shape, and one side of the kneaded material. And a thin plate for draining, which has a protrusion protruding in the thickness direction of the kneading part and embedded integrally with the kneaded material, and being integrally formed so as to be located at one of the outer peripheral parts of the formed body. A projection is formed on the back side of the roofing material, and the height of the projection does not exceed the depth of the recesses formed at predetermined intervals on the front side of the roofing material. The present invention is characterized in that the protrusion is provided in the recess when the competitors are stacked.

[0010]

In the above construction, the protrusion for preventing cracking is provided on the back side of the roofing material, and at the same time, the arrangement position thereof corresponds to the concave portion of the surface pattern formed on the front side of the roofing material. Due to the convex portions provided on the back surface side of the material, the support interval is narrowed, the load bearing strength is improved, stepping cracks can be prevented, and a large number of plates can be stacked so that they do not collapse.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the roofing material according to the present invention will be described below.

FIG. 1A is a plan view of a roofing material according to this embodiment, and FIG. 1B is a cross-sectional view taken along the line BB. As shown in these drawings, the roofing material 10 has
1 and a roof material main body 11 having a concave portion 22 formed at a position corresponding to the convex portion 21 on the surface side, and a draining thin plate 12 integrally provided at a side end of the roof material main body 11. ing.

In the present invention, the roof material body 11 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, and thickeners. 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 thin plate 12 for draining is, for example, shown in FIG.
As shown in (A), (B), and (C), the kneaded material has a projection 13 that stands upright in the thickness direction (D direction) of the roofing material body 11 having a flat shape, and a draining thin plate. Engagement ridges 15 are formed on the twelve flat plate portions 14 in the direction in which the projections 13 are erected.

The draining thin plate 12 is made of a metal or a synthetic resin and is formed by integral molding. When the roofing body is manufactured, the draining thin plate 12 and the roofing body 11 are interposed via the projections 13. And are integrally molded. In addition, the said draining thin plate 12 is not limited to being provided integrally with the side end part of the roofing material main body 11 as shown in FIG. 1, and is located in any one of the outer peripheral parts of the roofing material main body 11 as needed. Is fine.

As shown in FIG. 3, the height h of the convex portion 21 provided on the back surface side of the roofing material main body 11 exceeds the depth d of the concave portion 22 formed on the front surface side of the roofing material main body 11. There is no.

As a result, when constructed, the protrusions 21 serve as support members as shown in FIG. Also,
Even when a large number of sheets are stacked, since the concave portions 22 corresponding to the convex portions 21 are provided, as shown in FIG.
It is possible to prevent the stack 1 from interfering with the horizontal loading. Therefore, when many roofing materials are loaded,
It is extremely compact compared to the conventional one, and has improved transportability and storage.

[0018]

As described above with reference to the embodiments, the roofing material according to the present invention is provided with a protrusion for preventing cracking on the back side of the roofing material and, at the same time, the arrangement position of the protrusion is formed on the surface. Since it corresponds to the concave portion, it is intended to prevent stepping cracks and to improve the condition when the roof material is loaded.
