Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a corrugated tile.

[0002]

2. Description of the Related Art Conventionally, in the above-mentioned wavy tile, a plurality of convex ridges are formed in a horizontal direction, the ridges having upper and lower surfaces projecting upward from a ridge side edge to an eaves side edge. There was a horizontal corrugated tile.

[0003]

However, if one attempts to give the conventional tiles a solid appearance,
I had to make it a plank tile. Then, since the tile itself is a thick plate, the weight of the tile itself is large, and the effective laying area (working area) per sheet is small and the number of laying sheets is large, so that the workability is poor and the material cost is low. Further, there is a problem that it is difficult to reduce the operation cost. An object of the present invention is to solve the above-mentioned drawbacks and to provide a wavy tile sheet which has a heavy appearance in a laid state, is lightweight, and is excellent in workability and economy.

[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. One or a plurality of ridges are formed in the vertical direction from the right side edge to the left side edge of the bent mountain portion, and a nail hole forming portion is provided in a flat portion of the overlapped portion at the time of overlapping roofing, The point is that a ground contact portion is provided on the ridge side with respect to the nail hole forming portion, the lower surface of which is in contact with a field board when laying.

[0005] A second feature of the wavy tile according to the present invention is, as described in claim 2 of the claims, in addition to the above-mentioned first feature, the building from the nail hole forming portion. The point is that a flat portion is formed over the side edge.

The operation will be described below. According to the first characteristic configuration, in the laid state, in the laid state, the ridge portion formed from the right side edge to the left side edge forms a ridge portion in which the upper and lower surfaces project upward, from the eave side toward the ridge side. Presenting a step-like appearance, each step looks like the thickness of the tile plate, which can increase the feeling of weight, and furthermore, nails are nailed into nail holes provided in the nail hole forming part, and The wavy tiles can be fixed to the ground board, and when the wavy tiles are regarded as levers along the eaves ridge direction, the place fixed with the nails is provided at the fulcrum, the ridge side from the nail hole forming part. The grounded portion provided serves as an action point, and the action of the lever suppresses the lifting moment of the exposed portion on the eaves side from the fulcrum, thereby improving wind resistance. Needless to say, the lever is more effective when the nail hole is provided as close to the eaves as possible in the overlapped portion. In addition, since the nail hole is provided in the flat portion, nailing work is easy to perform, and even if the nail is damaged, the nail hole may be damaged as compared with the case where the nail hole is on the convex ridge portion. Is low. As a result, it is possible to ensure the wind resistance performance against the rising of the exposed portion in the laid state.

[0007] According to the second characteristic configuration, the nail hole can be provided in a wide area in the flat portion, and the contact area of the grounding portion with the ground plate is widened. The lifting moment of the exposed part is more effectively suppressed.

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

FIG. 1 and FIG. 2 are a perspective view and a side view showing an embodiment of a corrugated tile according to the present invention. The corrugated tile, the plate-like body containing cement, reinforcing fiber, special mixture, and water, is cut in advance into a pentagon having a ridge-side edge 8 composed of two sides when viewed from above, 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. As shown in FIGS. 1 and 2, a ridge is formed from the right side edge 2 to the left side edge 3, with the upper and lower surfaces projecting upward while the thickness of the wavy tile is kept constant. Two ridges 1 are provided in the ridge eave direction, and valleys sandwiched between the ridges 1 and flats 10, 7 on the ridge side from the ridges 1 closer to the ridge. Is formed. still,
The shape (hereinafter, referred to as a vertical cross-sectional shape) of each of the ridges 1 in a vertical section along the ridge direction is uniformly formed in a horizontal direction perpendicular to the ridge direction. The flat portion 7 is provided with a nail hole forming portion 4 having four nail holes 4a in the lateral direction along the eaves side edge, and the flat portion along the ridge side edge 8 of the wavy tiles. The lower surface side of 7 forms a ground contact portion 5 which comes into contact with a field board at the time of laying.
And the flat portion 7 constitute the overlapped portion 11 at the time of laying.
As shown in FIG. 2, each of the ridges 1 has a ridge-side wavefront 1 b closer to the ridge than the top 1 a of the ridges 1 compared to an eaves-side wavefront 1 c closer to the eaves than the top 1 a. The length in the eaves ridge direction is long, and the vicinity of the top 1a is constituted by a gentle curved surface.

Further, as shown in FIG. 1, the central part, the right side part 2 and the left side part 3 of the eave side edge 9 of the wavy tile board.

a and 3a are provided respectively.

As shown in FIG. 3, in the two wavy tiles vertically adjacent to each other, the right or left half of the upper surface 1d of the convex wavy portion 1 near the ridge side of the lower wavy tile is The left or right half of the lower surface 1e of the protruding ridge portion 1 near the eaves side of the upper wavy tiles is laid so as to face each other. The alignment marks 2a, 3a of the upper wavy tile
The alignment mark 9a of the upper wavy tile is further laid at the tip of the ridge side edge 8 of the two right and left wavy tiles laid on the lower side, respectively. It is positioned so as to coincide with the butted portion 12 of the two right and left wavy tiles.

FIG. 4 shows a three-level gradient (inclination angle of about 16.7 degrees).
FIG. 4 is a cross-sectional view in a vertical cross-section taken along a ridge house direction in FIG. 3, which is a side cross-sectional view of an overlapping state of the vertically adjacent corrugated tiles laid on a field board 6 of FIG. As shown in FIG. 4, in the upper wavy tile, the eaves side portion overlaps the overlapped portion 11 of the lower wavy tile from above, and the grounding portion 5 comes into contact with the ground plate 6. It is fixed to the base plate 6 by a nail 4b inserted through the nail hole 4a. In addition, the upper surface 1d of the convex ridge portion 1 closer to the ridge side and the lower surface 1e of the convex ridge portion 1 closer to the eave side have the same shape, and there is a gap between the upper and lower convex ridge portions 1. Since the thickness of the thin plate is effectively doubled particularly at the overlapping portions bent upward, the load resistance performance against step cracks and the like is improved. In addition, the maximum inclination angle formed between the ridge side wavefront 1b and the base plate 6 is about 12 degrees, and the wavy tiles are laid on the three-graded base plate 6 or the base plate with a slope higher than that. In this case, the water flow is not hindered.

Hereinafter, another embodiment will be described. The flat portion 7 is such that at least the nail hole forming portion 4 is flat,
