Abstract

PROBLEM TO BE SOLVED: To prevent corrosion of a nail and a batten and to ensure wind resistance by a method wherein a plurality of the crest parts, protruding upward, of upper and under surfaces and a plurality of protrusion-form wave parts produced throughout a portion ranging from end piece on the ridge side to the end piece on the eaves side are laterally juxtaposed. SOLUTION: A plate-form body containing cement is previously cut in a pentagonal shape in a plane comprised of two sides of an end piece part 3 on the ridge side and upper and under surfaces are molded in an uneven surface as water is supplied. In this case, a crest part where upper and under surfaces are upward curved in a protrusion-form manner as the thickness of a roof tile is maintained at a specified value is formed throughout a portion ranging from an end piece part 3 on the ridge side to an end piece part 4 on the eaves side to produce a protrusion-form wave part 1, and the four protrusion-form wave parts 1 are laterally juxtaposed. Further, positioning marks 4a and 7a during laying are arranged on the central part of the end piece part 4 on the eaves side and the ridge sides of end piece parts 7 on both right and left sides. Moreover, nail holes 8 are formed closer to the ridge side than a mating mark 7a of a flat part 7b extending along the end piece part 7 on both the right and left sides. This constitution provides excellent workability and load resistance and prevents levitation of a roof tile due to lateral displacement of the right and left gap parts of a top part 1a of the protrusion-form wave part 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a plurality of ridges which are formed from a ridge-side edge to an eave-side edge, and a plurality of ridges are formed in a lateral direction. It relates to a wavy tile.

[0002]

2. Description of the Related Art Conventionally, in a corrugated tile of this type, as disclosed in, for example, Japanese Utility Model Laid-Open No. 6-58020, a flat base portion between the adjacent ridges is provided.
In addition, nail holes were provided in flat portions along both left and right side edges.

[0003]

However, in the above-described conventional wavy tiles, the right and left side edges of one of the right and left adjacent wavy tiles are laid one on the other. When the abutting portion of the both end faces,
Since it is always disposed above one of the bases provided with nail holes, the wavy roof tiles laid on the lower side from the exposed part of the butting part penetrate into the lower surface of the left and right side edges. Reaching the nail hole along the base top surface of one of the boards, flooding to the roof base plate surface through the nail hole,
Furthermore, there was a risk of corroding the nail. An object of the present invention is to solve the above-mentioned drawbacks and to provide a corrugated tile having an effect of preventing corrosion of nails and a base plate and having excellent wind resistance.

[0004]

A first feature of the wavy tile according to the present invention for achieving this object is as described in claim 1 of the claims, in which the upper and lower surfaces are upward. A plurality of convex ridges are formed in the lateral direction so as to form a curved mountain portion from the ridge side edge to the eaves side edge, and within a base between the adjacent convex ridges. At the time of laying, a nail hole is provided only in a ridge-side overlapping portion of the first base portion on which the base portion of another tile board body is overlapped.

[0005] A second characteristic configuration of the corrugated tile according to the present invention is, in addition to the first characteristic configuration described above, as set forth in claim 2 of the claims, in addition to the first characteristic configuration described above. For a second base, which is the base excluding the first base,
The nail hole provided in the first base adjacent to the nail is located closer to the second base.

The operation will be described below. According to the first characteristic configuration, in the laid state, the second base portion, which is the base portion except for the first base portion in which the nail hole is not provided, is always arranged below the abutting portion, It is possible to prevent rainwater entering from the abutting portion from corroding the base plate through the nail or the nail hole. As a result, it is possible to provide a wavy tile board excellent in waterproofness.
In addition, since the nail hole is arranged in the ridge side overlapping portion, it is always concealed by the corrugated tiles that are laid on and adjacent to the upper side, so that rainwater does not directly flood.

However, in the first characteristic configuration, when the width of the second base portion is wide, the interval between the nail holes on both sides sandwiching the second base portion is longer than the interval between the other nail holes, and in the laid state. There is a fear that the wind resistance performance of the vehicle is impaired. However, according to the second characteristic configuration, the interval between the nail holes can be made more uniform, and when the strong wind blows under the convex ridge portion of the wavy tile, the second base portion is concentrated. It is possible to provide a corrugated tile having excellent wind resistance as well as waterproofness.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 are a perspective view showing an embodiment of a corrugated tile according to the present invention, and an elevational view from the side of the eaves viewed from the eaves side. The corrugated tile is a plate-like body including cement, reinforcing fiber, special mixture, and water, and a planar shape viewed from above is cut in advance into a pentagon in which the ridge side edge 3 has two sides, Further, the upper and lower surfaces of the plate-like body are formed by asperity molding by a press working device while water is being replenished. 1 and 2
As shown in FIG. 1, a convex ridge portion 1 is formed in which a mountain portion whose upper and lower surfaces are bent upward from the ridge-side edge portion 3 to the eave-side edge portion 4 while the thickness of the corrugated tile is kept constant. Are arranged side by side in four rows. In addition, three flat bases 2 are formed between each of the four protruding ridges 1, and one of the bases 2 at the center is a second base having no nail hole. In the portion 2b, two strips on both sides thereof are a first base portion 2a provided with a nail hole 6 in the ridge side overlapping portion 5. Further, on the ridge side from the center of the eave-side edge 4 and the center of the left and right side edges 7 of the wavy tile, the relative positional relationship between the adjacent wavy tiles when laying is determined. Alignment marks 4a and 7a are provided respectively. Further, nail holes 8 are respectively provided on the ridge side of the alignment mark 7a of the flat portion 7b along the left and right side edge portions 7.

As shown in FIG. 3, in the two wavy tiles adjacent to each other on the left and right sides, the right end face of the left and right side edges 7 of the left wavy tile and the right wavy tile The left and right side surfaces of the left and right side edge portions 7 are abutted against each other, and in the two wavy tiles vertically adjacent to each other, the right or left half of the ridge side upper surface 5a of the lower wavy tiles And the upper or lower corrugated tiles are overlaid so that the left or right half of the lower surface 9 of the eaves side overlapping portion faces each other. The two alignment marks 7a, 7a of the upper corrugated tile are respectively provided at the tips of the ridge side edges 3 of the two left and right corrugated tiles laid below, and The wavy tiles are positioned so that the alignment mark 4a coincides with the butted portion 10 of the two right and left wavy tiles laid below.

FIG. 4 is a plan view of the overlapping state of one set of the ridges 1 in FIG. 3 as viewed from above. FIG. 5 shows an overlapping state of the set of ridges 1 in FIG.
It is sectional drawing in A section. As shown in FIGS. 4 and 5,
The convex ridge portion 1 has an arc-shaped cross section in the transverse direction, and the radii of curvature r ₁ , r ₃ of the upper surface are longer than the radii of curvature r ₂ , r _{4 of the} lower surface by the thickness t, and the respective radii of curvature r _1, r _2, r
₃ and r ₄ are formed in the longitudinal direction from the eaves side edge 4 to the ridge side edge 3 so as to be gradually shorter and r ₁ > r ₂ > r ₃ > r ₄ . Further, the top 1a of the lower convex ridge portion 1 and the base portion 2 are in contact with the lower surface 9 of the eave side overlapping portion of the upper wavy tile, and further, the lower surface 9 of the eave side overlapping portion 9 The radius of curvature of each portion of each of the ridges 1 is set so that a gap 11 is formed between the top portion 1a and the base portion 2 between the ridge-side overlapping portion upper surfaces 5a.

According to the specific configuration shown in FIG. 5, in the wavy tiles vertically adjacent to each other, the load applied from above to the upper surface of the top portion 1a of the protruding wavy portion 1 of the upper wavy tile is increased by the upper wavy tile. The ridge wave portion 1 of the tile plate and the ridge wave portion 1 of the lower wavy tile plate are dispersed and act in the left-right direction, and the load finally acts on the base plate at the base portion 2. Therefore, the strength against stepping cracks is increased, and since there is the gap portion 11 on the left and right of the top portion 1a of the convex ridge portion 1 of the lower wavy tile, there is a margin for a displacement in the left and right direction,
