Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a roof for a building that has a double structure consisting of an inner roof part and an outer roof part.More specifically, the present invention relates to a roof for a building that has a double structure with an inner roof part and an outer roof part. This is a tiered roof made using members.

0002

[Prior Art] Modern buildings have various shapes, and along with the various shapes of buildings, the roofs are also circular, conical, annular, etc.
Alternatively, various shapes such as a dome shape, a polygonal or polygonal pyramid shape, and an arch shape are adopted. Roofs of the above-mentioned shape are mainly used for the roofs of large-scale factories, halls, gymnasiums, golf course clubhouses, and other buildings with large areas, but in most cases, the curvature surface is partially The polyhedron is divided into planar shapes to form descending ridges and/or descending valleys, and the partitioned planar polyhedrons are continued to form a curvature surface as a whole. For example, when the roof of a relatively large-scale building is to be roofed in a stepped manner, for example,
A roof board described in Japanese Patent No. -304250 is known. The device described in the above-mentioned publication has a main body curved in the transverse direction, and a lower part formed by bending toward the surface side along the upper edge of the main body and elongating the wall to be thinner than the main body. The roof is roofed in a step-like manner using a roof board that is integrally formed with a top part that is bent toward the back side along the lower edge of the main body part and has an uneven drawing shape.

0003

[Problems to be Solved by the Invention] However, when roofing is done in steps using the conventional roofing boards described above, the steps have uneven drawn parts, so the aesthetic appearance is not good when observed from the ground surface, for example. It's damaging and doesn't look good. In particular, a terraced roof is characterized by a large step between the upper and lower roof panels, so if there is an uneven part on the step, it will not work as a terraced roof. The value of will be significantly reduced. Additionally, when roofing is done by combining the seams of roof shingles, the seams are uneven, creating many microscopic voids, which reduces the rain protection function. Even if it is interposed in the combination of parts, a reliable waterproof effect cannot be expected. In addition, in roofs that have partially curved surfaces, where a flat linear general surface and a curved surface coexist, there are no unevenness formed in the portion that appears as a straight line, so the design of both portions is greatly improved. The result will be different.

[0004] Furthermore, there is a demand for a roof with a double structure consisting of an inner roof portion and an outer roof portion in order to ensure water leakage prevention, high strength, and improve heat insulation and sound insulation effects. If a curvature surface can be provided to the roof of this double structure, it is relatively easy to form a curvature surface by tiering the outer roof portion. However, the main purpose of the drainage board on the inner roof is to drain water in the event that water leaks from the outer roof, so it is necessary to prevent water from seeping into the attic even if water flows over the surface. It is necessary to ensure that water does not penetrate into the ceiling due to this phenomenon. Therefore, there is a need for a drainage board for the inner side of a double-layered terraced roof that can reliably shut off rain, is easy to construct, and can easily form a curved surface.

[0005]

[Means for Solving the Problems] The present invention was developed based on the above-mentioned requirements, and has an inner roof section and a stepped outer roof section, and the roof surface of the above-mentioned outer roof section is an outer roofing material having a first folded part whose front end is folded downward and a second folded part whose rear end is folded upward; The step structure member has an arc shape,
Alternatively, a receiving piece that is received by the first folded portion of the outer roofing material is provided at the upper end, and a fixing piece that is fixed to the rafters or the upper inner layer material is provided at the lower end.

[0006]

[Function] As mentioned above, the building roof of the present invention is constructed by roofing the outer roof part in a step-like manner using vertical step construction materials formed separately from the outer roof board, so that the step part is sufficiently covered. Not only can it be made taller, it also has a good appearance because there are no uneven parts, and the construction work is extremely simple.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below based on embodiments shown in the drawings. A roof 1 for a building according to the present invention is composed of an outer roof part 2 and an inner roof part 3 covering the indoor side of the outer roof part 2.

The above-mentioned outer roof section 2 has an outer roof material 4 shown in FIGS. 1 and 2, and a stepped member 5 located at the front end of the above-described outer roof material 4. The above-mentioned outer roofing material 4 is made of, for example, a metal plate and has a horizontally long band shape, a fan shape, or an arc shape, and has a first folded part 41 that is folded downward so as to overlap at the front end, and a first folded part 41 that is folded downward so as to overlap at the front end. A second folded portion 42 is formed in a folded shape so as to overlap on the upper side. If the outer roofing material 4 has an arc shape, it is preferable that the curvature of the front end 43 and the curvature of the rear end 44 of the outer roofing material 4 be approximately equal.

[0009] The above-mentioned step component member 5 is formed, for example, from a metal plate material, has a horizontally elongated shape that substantially coincides with the front end 43 of the outer roof material 4, is oriented vertically, and has a top end extending forward at a substantially right angle. A receiving piece 51 is provided so as to protrude, and a fixing piece 52 is provided at the lower end so as to extend rearward at a substantially right angle. If the outer roofing material 4 is a horizontally long strip-shaped plate material, the step-constituting member 5 may also be horizontally linear. However, if the outer roofing material 4 has a circular arc shape with a small radius of curvature, the step component 5 must also have a circular arc shape with a similar curvature; Since this is not possible, for example, V-shaped notches 53 are formed at appropriate intervals across the length direction of the receiving piece 51, and folds 54 that protrude or flatten are formed on the fixed piece 52. It is preferable to adjust it to the curvature of the outer roofing material 4 by adjusting it.

The outer roof part 2 of the present invention uses the above-mentioned outer roof material 4 and step structure member 5, but during construction, for example, a hat-shaped rafter 6 is arranged on the outdoor side of the inner roof part 3. An upper inner layer material 7 made of, for example, a wood wool cement board, a resin foam insulation board, etc. is laid between adjacent rafters 6, and an outer roof material 4 and a step component 5 are installed on the surface of the rafters 6 and the upper inner layer material 7. It covers the roof.

[0011] A specific method of covering the outer roofing material 4 and the step component member 5 is, for example, by engaging the second folded portion 42 and the fixing piece 52 with the rear end of the outer roofing material 4 located on the lower side. The step structure member 5 is made to stand upright, and the second folded portion 42 and the fixing piece 52 are connected in series by driving screws into the upper inner layer material 7, or by using a hanger (not shown). The second folded portion 42 and the fixing piece 52 are fixed to the surface of the rafter 6 and the upper inner layer material 7. In this state, the step structure member 5 is in an upright shape on the rear end 44 of the lower outer roof material 4, so the step structure member 5 is placed on the rear side of the upright step structure member 5 so as to match the slope of the outer roof material 4. The formed backing material 8 having a triangular cross section is disposed on the surface of the upper inner layer material 7 by adhesive or the like, and the outer roofing material 4 located on the upper side is arranged so as to cover the above-mentioned backing material 8. First folded portion 41 of outer roofing material 4
is narrowly attached to the receiving piece 51 of the step member 5 which is in an upright shape, and the first folded portion 41 is crushed or crimped to connect the front end 43 of the outer roofing material 4 and the receiving piece 51 of the step member 5. be fixed integrally. Then, the fixing piece 52 of the new step-constituting member 5 is engaged with the second folded portion 42 of the outer roofing material 4, and the rear end of the outer roofing material 4 is connected to the step with screws or hangers (not shown). The fixed pieces 52 of the constituent members 5 are fixed to the rafters 6 and the upper inner layer material 7, and the backing material 8 is arranged behind the fixed step constituent members 5, and the upper outer roofing material is attached to the step constituent members 5. 4 should be fixed.

Furthermore, the outer roofing materials 4 adjacent to each other on the left and right are shown in FIG.
As shown in FIG. 8, the side edges 45 of each outer roofing material 4 are overlapped vertically, and a scrap board 9 is placed inside the overlapping portion of the side edges 45 to connect them, or as shown in FIG. A first folded piece 46 that is bent upward is formed on the side end 45 of the roofing material 4, and a second folded piece 47 that is bent downward is formed on the side edge 45 of the other outer roofing material 4. , the first folded piece 46 and the second folded piece 47 of the left and right outer roofing materials 4 are locked, and a scrap board 9 is placed inside to connect them, or as shown in FIG. A waste board 9 is arranged inside the side end 45 that the roof material 4 contacts, and a cover 10 is attached to the surface to connect it, or a joint 11 is provided on the surface of the waste board 9 as shown in FIG. The side ends 45 of the left and right outer roofing materials 4 are connected to the left and right horizontal fitting grooves 111, 111 of the joint 11.
The cover 10 is attached to the surface and connected. In this case, since each of the outer roofing materials 4 is firmly attached with screws or hangers, there is no need to consider the strength of the connecting portions of the left and right outer roofing materials 4.

If necessary, between the first folded part 41 of the outer roof material 4 and the receiving piece 51 of the step component 5, and between the fixed piece 52 of the step member 5 and the second folded part of the outer roof material 4, It is preferable to provide a waterproof treatment by interposing rubber packing, adhesive tape, etc. between the folded portion 42, or by applying a caulking agent or a sealing agent made of silicone resin or the like. Additionally, if the side edges 45 of the outer roofing materials 4 that are adjacent to each other on the left and right overlap vertically, the overlapped areas should also be waterproofed with caulking agent or the like as described above to prevent rainwater from penetrating. is preferable.

As described above, the outer roofing material 4 is installed in order from the bottom.
When the outer roof is roofed by fixing it to the surface of the rafters 6 and the upper inner layer material 7, a vertical step member 5 is formed between the rear end and the front end of the upper and lower outer roof materials 4, as shown in FIG. Intervening and becoming a step part,
