[0005]

Means for Solving the Problems The technical problems described above are:
This can be effectively solved by the present invention. That is, the roofing material according to the present invention is formed of a fiber-reinforced concrete plate having a plane shape of a substantially parallelogram, and has an upwardly extending upper surface extending substantially in an L shape along two sides sandwiching one corner of the parallelogram. A ridge is formed, a locking projection having a fixing hole is formed on the lower surface, and a downward ridge is formed on each of two sides symmetrical to the upward ridge, and the upward ridge and the downward ridge are adjacent to each other. It has a notch in a portion which is an overlap margin with a corner portion of the material. The term "parallelogram" as used herein refers to all quadrilaterals in which two opposing sides are parallel to each other, that is, includes not only a parallelogram in a narrow sense, but also a rectangle, a square, and a rhombus. In addition, "fiber reinforced concrete" refers to concrete in which the mechanical strength is enhanced by mixing an appropriate amount of synthetic fiber, glass fiber, or the like.

[0006] The roofing material of the present invention is laid in a large number in a state of being partially overlapped like a scale along the slope of the roof. In each of the roofing materials, a vertically extending portion of the L-shaped upward ridge is substantially parallel to the gradient direction, and a laterally extending portion of the upward ridge is a higher side of the gradient. Placed in

In this laid state, one of the two downward projections is a vertically extending portion of the upward projection of the roof material adjacent in the lateral direction (a direction perpendicular to the gradient direction, that is, the horizontal direction). The lower ridge, which covers from the outside, covers the laterally extending portion of the upward ridge of the roofing material adjacent to the lower side of the slope from the lower side. In addition, the corners of another adjacent roofing material are located at the cutout portions of the upward ridge and the downward ridge, and are overlapped. With such a laying form, rainwater is smoothly drained without rainfall during rainfall, and intrusion (leakage) into the inside of the roof is reliably prevented.

In addition, the locking projections of each roof material are hooked on the roof tiles of the roof, and are fixed through screw holes or nails screwed or driven into the roof tiles through the fixing holes of the locking projections. You. That is, in this case, the roofing material is directly fixed to the roof tile bar by a screw member or a nail, and the mechanical strength is large, so that a base plate as a base material can be unnecessary.

In the above-mentioned roofing material, more preferably, a heat insulating material is integrally provided on the entire lower surface except for the portions where the downwardly projecting ridges and the locking projections are formed. With such a configuration, it is not necessary to separately provide a heat insulating material when installing the roof.

In the manufacture of a roofing material having a heat insulating material integrally provided on a lower surface, a heat insulating material is laid on a surface corresponding to the lower surface of the roofing material on an inner surface of a mold for molding the roofing material. The mold is closed, and the mold is filled with concrete mixed with reinforcing fibers. In this case, since the heat insulating material is integrated with the lower surface of the roof material formed by curing the concrete in the mold, a separate bonding step is not required.

FIGS. 3 and 4 schematically show a roofing construction using the above-described roofing material 10. In these figures, reference numeral 31 denotes a ridge and a purlin (not shown) of the roof of a wooden house. A rafter 32 supported by (haze) and erected at a predetermined slope, 32 is placed on the rafter 31
This is a roof tile that is driven at a right angle to 1. The roofing material 10 according to this embodiment is provided on the inclined roofing material support grid 30 composed of the rafter 31 and the tile bar 32 in a state of being partially overlapped with each other in a scale-like manner along the gradient.
A large number of the short side portions 11a in FIG. 1 are arranged vertically and horizontally along the roofing material support grid 30 so that the downwardly protruding ridges 12 along the short side of the gradient face the low side.

Here, of the many roofing materials 10 laid on the roofing material support grid 30, for example, an arbitrary roofing material 1
Focusing on 0A, the downward protruding ridge 12 along the short side on the lower side of the roofing material 10A lowers the short side portion 11a of the upward protruding ridge 11 on the roofing material 10B adjacent to the lower side of the roofing material 10A. The downward projecting ridge 13 along the long side is overlapped so as to cover the long side portion 11b of the upward projecting ridge 11 in the roofing material 10C adjacent to the left side of the roofing material 10A from the outside. ing. In addition, for example, the notch 13 on the high side and the left side of the lower surface of the roofing material 10A.

The lower surface (notch 12b) of the lower / right corner 10a overlaps, and the lower / left notch 11c of the roofing material 10A is the lower end of the long side portion 11b of the upwardly protruding ridge 11 of the roofing material 10C. Are overlapping. The other roofing materials 10 have the same relationship as the two roofing materials 10 arranged adjacent to the lower side and the left side, respectively.

The protruding height of the downward protruding ridge 12 along the short side is formed higher than the protruding height of the downward protruding ridge 13 along the long side in the laid state shown in FIG. This is because the step between the roofing material 10A and the roofing material 10B adjacent to the lower side is larger than the leveling difference between the roofing material 10A and the roofing material 10C adjacent to the side (left side) thereof, and this difference in level is accommodated. By doing so, the peripheral edges of the respective roofing materials 10 are substantially in close contact with each other, and it is possible to effectively prevent the intrusion of rainwater and the blowing of wind into the interior space of the roof.

Higher-side locking projection 1 on each roofing material 10
Numeral 4 is fixed by a screw member 33 which is hung on the roof tile 32 and screwed into the roof tile 32 through the fixing hole 14a. The lower end of each roofing material 10 is:
The downward projecting ridge 12 is supported by being overlapped on the upper end of the roofing material 10 adjacent to the lower side. In addition, since the roofing material 10 is a molded product of high-strength concrete reinforced with fibers as described above, the strength is large, and the heat insulating material 15 is integrally joined to the lower surface thereof. There is no need to stick a base plate for attaching the heat insulating material.

In the perspective view of FIG. 3, for convenience, the thickness of each roofing material 10, the upward ridges 11, and the downward ridges 12, 1 are shown.
3 is exaggerated, so that the roofing materials 10, 10,
Are shown so that a large step is formed at the overlapped portion of...
The ratio of the plate thickness and the height of the protrusions of the upward ridges 11 and the downward ridges 12, 13 to the area of the projections is much smaller than that shown in the figure. Accordingly, in the mounting structure, the lower locking projections 14 of each roofing material 10 do not float up from the rafters 31 as shown in FIG. The locking projection 14 may be fixed to the roof tile 32. Further, also in the lateral direction, each roofing material 10 does not become in a state of being greatly inclined with respect to the roof tile 32 as shown in FIG.

In the above embodiment, the roof material 1
Although the plane shape of 0 is a substantially rectangular shape, a square shape, a rhombus shape, and the like can also be implemented.

Further, the roof tiles 3 in the roof material support grid 30
By narrowing the arrangement interval of 2, the overlapping margin of each roofing material 10 may be larger than in the mounting state shown in FIG. 3, FIG. 4, or FIG. Further, the fixing hole 14a may be formed as a female screw, and a bolt inserted into a hole previously opened in the tile bar 32 may be screwed into the fixing hole 14a. That is, in this case, the metal pipe 16 embedded in the locking projection 14 is a nut. State.

Further, in the above embodiment, the roof material 1
Although the description has been given of the case where the heat insulating material 15 is integrated with the lower surface of the zero, the structure without the heat insulating material 15 may be used in the case where the heat insulating material 15 is used for the roof of a building that does not need heat insulation, such as a bicycle yard. Furthermore, various changes can be made to the shape of other details.

[0026]

According to the present invention, the following effects are realized. (1) Since each roofing material can be directly attached to the roof tile, there is no need to insert a base plate as a base material, so that the construction period can be shortened and the construction can be performed at low cost. (2) Since the heat insulating material is integrated with the lower surface of the roof material, there is no need to separately lay the heat insulating material on the lower surface side of the roof material at the time of roof construction, which also shortens the construction period and construction cost Can be reduced. (3) In the manufacture of a roofing material in which a heat insulating material is integrated on the lower surface, since the heat insulating material is integrated on the lower surface simultaneously with the molding of the roofing material by concrete, it can be manufactured in a small number of steps and at low cost.
