Abstract

(57) [Summary] [Purpose] At the time of construction, play is provided in the overlapping part of the corrugated parts so that the corrugated parts stacked on top may not float. [Structure] A flat surface portion 1 in the lateral direction and a corrugated portion 2 protruding upward.
And are provided alternately. The width of the corrugated portion 2 is formed such that the ridge side is narrow and the width gradually increases toward the eaves side.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flat roof tile having a structure in which flat portions and wavy portions are alternately provided in the lateral direction.

[0002]

[Prior art]

 2. Description of the Related Art In recent years, flat tiles have been provided in which flat portions in the lateral direction and wavy portions that slightly bend upward are provided alternately. The wavy portion is provided to improve the external appearance, but the height of the wavy portion is made low so as to prevent cracking.

[0003]

[Problems to be solved by the device]

 However, in such a conventional example, since the width of the wavy portion is the same width in the eaves ridge direction, when the flat roof tiles are roofed, the overlapping of the flat roof tiles adjacent to each other in the eaves ridge direction is a little misaligned. Then, the wavy portions do not completely match with each other, and the wavy portions overlaid on each other float. As a result, the strength of the flat roof tile on the roof surface is extremely reduced, which causes a problem such as a stepping crack.

The present invention has been made in view of the above problems, and an object of the present invention is to have a play in an overlapping portion between corrugated portions during construction so that a corrugated portion overlaid may float. It is to provide a flat roof tile that does not have the risk of

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the flat roof tile A of the present invention is provided with a flat portion 1 and a corrugated portion 2 protruding upward alternately in a lateral direction, and the corrugated portion 2 has a narrow width toward the eaves. The width was gradually increased.

[0006]

[Action]

 According to the above configuration, when the flat tile A is roofed on the roof surface, the wavy portions 2 of the flat tiles A adjacent to each other in the eaves direction overlap each other, but since the wavy portion 2 on the eave side that overlaps above is wide, The flat roof tiles A that overlap with each other do not float up even if the overlaps are a little off.

[0007]

【Example】

 As shown in FIG. 1, the flat roof tile A is formed by alternately providing a flat surface portion 1 and a corrugated portion 2 protruding upward in the lateral direction. The corrugated portion 2 has a small height that slightly protrudes upward, and in this embodiment, three ribs are provided. The width of the flat surface portions 1 located on both sides of the flat surface portion 1 is about half the width of the flat surface portions 1 located between the adjacent wavy portions 2. The wavy portion 2 is formed so that the width on the ridge side (non-exposed portion) side is narrow and gradually widens toward the eaves side (exposed portion) side. That is, when the width of the corrugated portion 2 on the ridge side is a and the width on the eaves side is a ', the relationship of a <a' is established.

Then, as shown in FIGS. 2 and 3, the flat roof tiles A are arranged laterally on the roof surface and are arranged in the eaves direction to roof the roof. Side edges of adjacent flat tiles A in the left-right direction are abutted against each other, and flat tiles A adjacent to the eaves ridge direction are flat roof tiles A located on the ridge side on the upper surface of the non-exposed portion of flat roof tiles A located on the eave side. The lower surface of is stacked. Further, the flat tiles A that are adjacent to each other in the eaves direction are offset from the flat tile A located on the side of the eaves by 1/3 of the width of the flat tile A in the lateral direction. When the lower surface of the exposed portion of the flat tile A on the ridge side is overlapped with the upper surface of the unexposed portion of the flat tile A on the eaves side, the flat portions 1 overlap each other and the corrugated portions 2 overlap each other. When the wavy portions 2 overlap each other, the width of the wavy portion 2 on the eave side that overlaps the upper portion is wider than the width of the wavy portion 2 on the lower ridge side. It can be installed so that the eaves side of the roof tile A does not rise.

[0009]

[Effect of device]

 As described above, the flat tile of the present invention is formed such that the width of the corrugated part is narrower on the ridge side and gradually widens toward the eaves side. The wavy portions of adjacent flat tiles overlap with each other, but since the wavy portion on the eave side that overlaps with each other is wide, it overlaps with play, and even if the overlap overlaps a little, the flat tile that overlaps will float. This will prevent the flat roof tile from cracking on the floor and facilitate the lateral position adjustment of the flat roof tile during construction.
