2. Description of the Related Art In recent years, roofing materials such as clay, concrete, and slate, as well as steel plates with various surface treatments and aluminum roofing materials have excellent waterproof, fireproof, and earthquake resistant functions, and are economical. It has been gaining attention as a roofing material and is becoming more popular.

In Japanese Patent Laid-Open No. 4-258449, as shown in FIG. 9 (longitudinal section) and FIG. 10 (perspective view), the flow of rainwater blown up along the slope of the roof due to the influence of strong wind causes the exterior plate ( We have proposed a building exterior structure with improved waterproofness under strong wind and rain by providing a means for preventing the phenomenon of concentrating in the gap between the roof tiles). That is, as shown in FIG. 9, the strip-shaped exterior plate 3
2 Upper edge forming portion 33 that is folded back to the surface side along the upper edge of the main body
And forming a lower edge molding portion 34 that is folded back to the back surface side along the lower edge of the main body of the exterior plate 32.
2 is a building exterior structure in which the upper edge and the lower edge both molding portions 33 and 34 adjacent to each other are joined and joined to each other on the base 31 of the building exterior, and the joint portion 36 of the exterior plates 32 is joined. A step portion 35 rising from the surface of the exterior plate 32 along the lower side (within 10 mm from the lower end of the lower edge molding portion)
Is formed. It should be noted that the exterior plates 32 that are sequentially laid on the base 31 of the roof surface are adjacent to each other in the upper stage and the lower stage. To be joined. Therefore, the rainwater that flows backward on the roof surface is not affected by the presence of the step portion 35 and the gap 3 of the joint portion 36.
It will flow over 7. As a result, a space a which the flow does not reach can be formed behind the step portion 35, and the gap 37 serving as the inlet of the flooded water is located in this space a, and the phenomenon that the backflow of rainwater directly hits is avoided. It As a result, it is said that the infiltration of water from the gap 37 of the joint portion 36 is effectively prevented. In FIG. 9, 31a is a plywood, and 31b is a base sheet. FIG. 10 corresponds to FIG.
FIG. 10 is a perspective view showing a vertical section of an exterior plate of the building exterior structure (flat plate type thatched roof structure), and parts having the same names as in FIG. 9 are given the same reference numerals. 38 indicates rainwater.

Further, Japanese Patent Application Laid-Open No. 5-33427 proposes a method for constructing a roof material at a joint portion of a roof unit or a roof panel. That is, the construction method is such that a roof material is pre-installed on a portion other than the vicinity of a connection portion with another divided roof on the divided roof portion of the unit building, and after the divided roof portion is assembled, the inclination of the divided roof portion A roofing material construction method in a unit building in which a roofing material is constructed on a connecting portion in the direction and a metal-molded short roof tile is used as the roofing material. The metal-molded short roof tile is nailed and attached to the pier fixed to the split roof portion. An example of a concrete construction method will be described based on FIG. 11 (longitudinal sectional view).
After attaching waterproof paper (liner roofing) 44 on the roof boards 42, 43 of the roof panels (divided roof parts) 40, 41 of the unit building, the pier 4 according to the assigned allocation.
5 is fixed.

Then, in the factory, the roof panel 40,
The metal-molded short roof tiles 46 as roofing materials are attached to the pier 45 from the outside by screw nails 50 on most of the portions other than the vicinity of the connecting portion 49 in the inclination direction of 41, and plural roof panels 40, 41 are provided in the inclination direction. Fix the stage. At this time, when the roof panels 40 and 41 are assembled in a unit building and connected in the inclination direction, in the vicinity of the connection portion 49 in the inclination direction of the roof panels 40 and 41, along the connection portion 49 orthogonal to the inclination direction when the roof panels 40 and 41 are connected in the inclination direction. Thus, the portions where the metal-molded short roof tiles 46 are not attached are provided at intervals of one sheet of the metal-molded short roof tiles 46, and the waterproof paper 44 is exposed.

As described above, the roof panels 40 and 41 to which the metal-molded short roof tiles 46 are attached in advance in the factory are
After being transported to the construction site of the unit building and assembled to the unit building, the waterproof papers 44 of the adjacent roof panels 40 and 41 are overlapped at the connecting portion 49 in the inclined direction, and the tape material 51 is attached to the roof panels 40 and 41. Paste it over. After this, the connecting portion 4 of the roof panels 40, 41
On the exposed portion of the waterproof paper 44 in 9, a metal-molded short roof tile 46 is installed. At this time, as shown in FIG. 11, the upper edge 53 of the metal-molded short roof tile 46 is inserted in a state in which the lower edge 52 of the metal-molded short roof tile 46 on the upper stage side that has been attached in advance is lifted and elastically deformed to be stacked. Together with matching, the lower edge portion 52 of the metal-molded short roof tile 46 is superposed on the upper edge portion 53 of the lower metal-molded short roof tile 46 that is previously attached, and then the screw nail 50 is attached to the roof panels 40, 41.

Construction work time for roofing materials on site will be greatly reduced, and the parts handled on the roof will be smaller. Since the metal-molded short roof tile is used as the roofing material, this metal-molded short roof tile can be elastically deformed, and other metal-molded short roof tiles can be easily inserted and stacked, and the metal-molded short roof tile can be attached at the connection part. Is extremely easy.

Further, it is said that the metal roof tiles can be attached to the stiles on the divided roof part by nailing them so that the roofing material can be attached so as to sufficiently withstand the blowing load due to the wind.

Next, in Japanese Patent Laid-Open No. 5-33428, as shown in FIG. 12, except for the vicinity of a connecting portion 49 with the other divided roof portions 41, 40 on the divided roof portions 40, 41 of the unit building. Roof material 46 is pre-installed on the part,
After assembling the split roof parts 40 and 41, the split roof part 4 in the lateral direction
A roof material 46 is constructed by a zigzag roof on the connecting portion 49 between 0 and 41, and a metal-molded short roof tile is used as the roof material 46. In addition, metal-molded short roof tile
A roofing material construction method is proposed, which is attached by nailing to the pier 45 fixed on 0, 41. The method for assembling the metal-molded short roof tiles and the nailing work is described in the above-mentioned JP-A-5-3.
This is similar to the case of Japanese Patent No. 3427. In addition, 50 shows a screw nail. The roof construction method proposed in this proposal also aims to shorten the time required for the construction work of the roof material on site.

[0009]

As described above, various improved techniques have been proposed, but the problems at present are listed below. Clay roof tiles and iron plate roof tiles are common, and these have poor thermal conductivity. When the above roof tile is used, the roof becomes heavy and the earthquake resistance is poor. Clay roof tiles and baked roof tiles are easily broken in cold regions. The flat plate (sheet-like) shape is inferior in stereoscopic effect. If the roofing material is nailed from the outside, rainwater may enter through the nail holes, which may cause a problem. When the roofing material is nailed from the outside, the nail head is visible from the outside, which impairs aesthetics. From the viewpoint of shortening the construction period, ease of laying roof material is desired. The present invention has been made in view of these problems, and an object thereof is a roof structure that is easy to lay roof tiles, and is a metal tile such as a lightweight aluminum press-molded article, and is earthquake-resistant. By using a roof tile that is excellent and has a heavy weight, and has a structure that is not nailed from the outside,
It is to provide a roof structure that prevents rainwater from entering and does not spoil the appearance. In addition, the roof tile roof tile in the present invention means a tile-shaped roof tile of various forms such as a cross tile and a sleeve tile, which are usually made of clay, and is close to an S-shaped roof tile.

[0010]

Means for Solving the Problems The inventors of the present invention, as a result of earnest research in view of the above-mentioned object, use a metal roof tile roof tile made of metal, pay attention to a method of joining the roof tile roof tiles, and facilitate the construction. In addition, we have completed a three-dimensional roof structure with a good aesthetics.

That is, the roof structure of the present invention is a roof tile made of a plate-shaped metal roof material having a concave portion at a portion to be nailed, and the roof tile roof and the concave portion are provided. It is characterized by comprising a hanging member to be attached, and the inside of the folded-back portion of the main tile roof tile is fitted to the outside of the folded portion of the lower portion of the hanging member.

Further, the roof structure of the present invention is characterized in that a plate-shaped metal roof material is formed into a main tile-like roof tile, and the main tile-like roof tile and the suspension are integrated by welding. To do.

It is characterized by being integrally molded.

As the main tile-like roof tile applied to the present invention,
A press-formed product made of aluminum, copper, or a steel plate may be used, but a press-formed product made of aluminum is preferable from the viewpoints of weight reduction and corrosion resistance. An oxide film (usually 6 to 15 μm) may be formed on the surface of the aluminum press-formed product. Alternatively, a colored aluminum plate or a colored steel plate may be press-molded to form the roof tile roof tile applied to the present invention. It should be noted that, depending on the complexity of the shape of the roof tile-like roof tile, it can also be manufactured by an aluminum cast product.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Aluminum alloy wrought material (100
0 mm and 5000 mm) 1 mm thin plates were subjected to shearing and press-molded at a pressure of 300 tons into a heavy roof tile-like shape. In the present invention, a conventional clay roof tile has a horizontally long shape integrally formed horizontally and has a horizontal length of 800 m.
m. Therefore, the roof tile of the present invention is easy to lay and is made of aluminum that is press-formed, so it is lighter than conventional clay and steel plate products, and can reduce heavy labor and is excellent in earthquake resistance. It has a roof structure. The tile roof tile may be an aluminum casting. Alternatively, a color aluminum plate, a color steel plate, or a copper plate may be press-molded to be manufactured.
