BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building roof having a double structure consisting of an inner roof portion and an outer roof portion. The roof with a curved surface is formed on the left and right side edges of the drainage plate by forming overlapping sections with open lower surfaces and by varying the lateral width of the left and right overlapping sections, depending on the overlapping state of the overlapping sections of the drainboards on the left and right. It is characterized in that it can be installed easily and surely.

2. Description of the Related Art Recent buildings have various forms, and the roofs have a circular shape as shown in FIG. 1A, a conical shape as shown in FIG. 1B, and a dome. Shape, polygon or pyramidal shape shown in FIG. 1 (C), FIG. 1 (D)
Various shapes such as the bow shape shown in are adopted. The roof with the above-mentioned shape is mainly used for roofs of large-scale and large-scale factories, halls, gymnasiums, clubhouses of golf courses, etc., but most roofs have an arcuate curvature surface. The ridges a and / or the valleys b are formed by dividing them into a planar shape, and the divided small planar polyhedrons are continuous to form a curved surface as a whole. Therefore, when constructing the base part, a tapered surface or plate is formed as designed at the construction site so as to correspond to a small planar polyhedron, and this surface or plate is continuous to form a polyhedron. There is.

[0003]

However, as described above, when a polyhedron is formed by forming a taper surface or plate on the spot and making it continuous, minute voids are generated in the connecting portions of the adjoining polyhedrons and rainwater is generated. May penetrate or wind may blow, and when using a straight plate when forming a tapered surface or plate, triangular parts are generated on the left and right side edges, so the roof plate that constitutes the roof Since the shape and length of rafters are not constant, highly skilled roof construction technology is required. For example, as shown in FIG. 2, when the fan-shaped surface B is formed by using a plurality of strip-shaped parallel plate materials A, only the rectangular surfaces can be formed by simply arranging the plate materials A in parallel. It is necessary to connect the triangular plate material A'to. In this case, if the plate material A is a roof plate or a drain plate, rafters are located at the connection portions C of the plate materials A that are adjacent to each other on the left and right, and the rising portion of the roof plate is located, but the connection portion C is a straight line. Due to the shape, the construction is relatively easy. However, since the outer edge portions C ′ of the plate materials A ′ on the left and right side ends are different in length from the connecting portion C, if the fan-shaped surface B is continuous, the above-mentioned water leakage and construction defects will occur. When it is necessary to cut the upper edge portion of the plate material A located second from the side edge in a slanted shape, a fine gap is formed unless it is performed by a more skilled technique. Water may leak or wind and rain may blow. When the polyhedron is made to have an extremely small area and continuous in order to make the curved surface of the roof smooth, the connecting portion of the polyhedron remarkably increases, so that the above-mentioned drawbacks become conspicuous.

In addition, a double-structured roof having an inner roof portion and an outer roof portion has been proposed in order to ensure prevention of water leakage and to have high strength and to improve heat insulation and sound insulation effects.
When providing a curved surface to this double-structured roof, the roof material for the outer roof part can be tiles, tiles, roofing roofing boards, natural slate boards, etc. with a relatively small area, so the curved surface is configured. It's easy to do. However, the drainage plate of the inner roof part is mainly intended for drainage function when water leaks from the outer roof part, so it is necessary to prevent it from soaking into the ceiling even if water flows on the surface. Therefore, water must not penetrate. Therefore, there is a demand for a drainage plate on the inside of a double-layered roof that has a reliable rain finish, is easy to install, can be worked in a short period of time without requiring skill, and can have a curved surface easily. ing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments of the drawings. The roof 1 for a building of the present invention has an inner roof portion 2 and an outer roof portion 3 that is roofed on the outdoor side of the inner roof portion 2.

According to the first embodiment of the present invention shown in FIGS. 3 and 4, the inner roof portion 2 is directly on the upper surface of the steel frame purlin 4 made of a channel material, or is made of hard wood wool board, foam cement board or the like. The drainage plate 6 is laid on the upper surface of the lower inner layer material 5, and the roof base portion 7 is the steel frame purlin 4 or the lower inner layer material 5 is laid on the upper surface of the steel frame purlin 4. As shown in FIG. 5, the drain plate 6 has a wide first overlapping portion 9 on one side edge portion of a drain portion 8 through which water flows and a narrow second overlapping portion 10 on the other side edge portion. Is formed.

The first overlapping portion 9 and the second overlapping portion 10
Is a rising piece 11 rising upward from the side edge of the drainage portion 8 in an inclined shape, an upper surface piece 12 extending laterally outward from the upper end of the 11, and a short downward direction from the tip of the upper surface piece 12. It is a hollow shape whose bottom surface is open. The first overlapping portion 9 and the second overlapping portion 10 have different horizontal widths because the upper surface pieces 12 have different horizontal widths, and when the drainage plates 6 are arranged side by side, the adjacent drainage plates 6 are adjacent to each other. The second superposed section 10 is superposed on the inside of the first superposed section 9. Therefore, a plurality of the drainage plates 6 having the above-described structure are laid in parallel in the lateral direction, and the second overlapping portions 10 of the adjacent drainage plates 6 are polymerized so as to be housed inside the first overlapping portion 9, When the second overlapping portion 10 is inclined inside the first overlapping portion 9, each drain plate 6 gradually becomes inclined as shown in FIG. 6, and when a plurality of drain plates 6 are arranged side by side, it is fan-shaped. The surface portion S can be formed. In particular, as shown in FIGS. 6 to 8, the second overlapping portion 10 is located inside and outside the first overlapping portion 9 at the lower end of the drainage plate 6, and the second overlapping portion 10 is located at the upper end of the drainage plate 6. When tilted so as to be located inside the first overlapping portion 9, it is possible to form a fan-shaped surface portion S having a wide lower portion and a narrow upper portion as a whole.

In FIG. 6, four drain plates 6 are horizontally connected in parallel to form one surface portion S, but for example, a surface portion S in which six drain plates 6 are arranged side by side in the lateral direction. Is further connected in the lateral direction, a large fan-shaped curvature surface can be formed as shown in FIG. In addition, as shown in FIG. 10, the drainage portion 8 has a taper shape in which the lateral width of the lower end is wider than the lateral width of the upper end, and the left and right side edges of the drainage portion 8 have the same first overlapping portion 9 as described above. When the surface portion S is formed by using the drainage plate 6 having the second overlapping portion 10, the surface portion S in which the lateral widths of the upper end and the lower end largely change can be formed.
Therefore, by appropriately selecting the difference in lateral width between the first overlapping portion 9 and the second overlapping portion 10 in the drainage plate 6 and the drainage portion 8 in which the taper is formed, the fan shape of the surface portion S can be freely set. Can be set to. Further, when the surface portion S is configured as described above, the drain plates 6 having the same standard dimensions can be used, and the drain plates 6 adjacent to each other can be used.
The rafter that supports the connection part of the side edge of the inside from the inside can also use the thing with a fixed length.

The drainage plate 6 is formed by press-forming a long strip-shaped metal plate to form the left and right first overlapping portions 9,
The second overlapping portion 10 can be formed. However, if the drainage portion 8 has a tapered shape, it is difficult to integrally form the first overlapping portion 9 and the second overlapping portion 10 on the left and right at different intervals from one end portion to the other end portion. 9 and the second overlapping portion 10 may be press-molded individually. Also,
In addition to press molding, for example, a cantilever roll molding machine can be used to mold the first overlapping portion 9 and the second overlapping portion 10 of the drain plate 6. That is, in the roll forming machine, a pair of upper and lower rolls are juxtaposed in parallel, a metal plate material is sequentially passed between the pair of upper and lower rolls, gradually bent from the first stage roll, and formed into a desired shape by the final stage roll. Of. Therefore, after one side edge of the drainage plate 6 is roll-formed to form the first overlapping portion 9, then the other side edge of the drainage plate 6 is roll-formed to form the second overlapping portion 10. In this way, when the first overlapping portion 9 and the second overlapping portion 10 on the left and right edges are roll-formed differently, the first overlapping portion 9 having a complicated shape,
Even the second overlapping portion 10 can be molded extremely easily and efficiently.

In the first embodiment of the present invention, the drainage plates 6 are laid on the upper surface of the roof base portion 7 so as to be juxtaposed in the lateral direction, and the first overlapping portions 9 of the drainage plates 6 adjacent to each other on the left and right sides are provided.
