[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roofing structure.

[0002]

[Prior art]

 Conventionally, there is a roofing structure shown in Fig. 6 as a roofing structure in which the eaves side of the second roofing material on the ridge side is superposed on the first roofing material on the eaves side and raised in a staircase shape. In FIG. 6, a roof material mounting body 1 indicated by rafters having a field board is attached to a roof house (not shown) with a roof slope, and the first roof material on the eaves A side is mounted on the roof material mounting body 1. 2 is overlapped with the eaves side of the second roofing material 3 on the ridge side B, and it is raised like a staircase.

That is, wood caskets 4 are arranged on the base plate at intervals in the roof flow direction C, and engagements formed on the wood caskets 4 on the ridge side of the first and second roof materials 2, 3 It is raised by engaging the protrusions 2A and 3A and fixing them by the nail 5.

[0004]

[Problems to be solved by the device]

 In the prior art shown in FIG. 6, when the roof materials 2 and 3 are not fastened by the nails 5, the roof materials 2 and 3 are scattered, while the roof materials 2 and 3 are fastened even if they are fastened by the nails 5. The timbers 2 and 3 only overlap the eaves side of the next-stage roofing material on the ridge side of the eaves side roofing material, and are not fixed by nails 5, so the wind flow shown by arrow D in Fig. 6 is shown. There was a limit to improving the waterproof performance and wind resistance. Also, it was difficult to replace the roofing material because it was nailed.

Therefore, the present invention provides a roofing structure that improves the efficiency of roofing construction, improves wind resistance to some extent without nailing, and facilitates replacement of roofing materials. That is the purpose.

[0006]

[Means for Solving the Problem] The present invention provides a roofing structure in which the eaves side of the second roofing material 14 on the ridge side is superposed on the first roofing material 13 on the eaves side, and is raised in a stepwise manner, In order to achieve the above-mentioned purpose, the following technical measures are taken. That is, the present invention is provided with the engaging projections 13A, 14A on the back surface of the ridge-side of the 1.2th roofing material 13, 14, and the engaged projections 13A, 14A for engaging and disengaging the engaging projections 13A, 14A. The roof member mounting body 10 is provided with the crosspiece 12 having the joint portion 12A, and the engaging projections 13A and 14A are unevenly distributed to the ridge side from the eaves side edge of the upper roof members 13 and 14. The engaging part 12A is provided with a lift permitting part 12E on the eaves side with the engaging protrusions 13A, 14A of the upper roofing materials 13, 14 as a base point to allow replacement of the lower roofing materials 13, 14 It is characterized by that.

[0007]

[Action]

 After installing the crosspiece 12 having the engaged portion 12A with a space in the roof flow direction on the upper surface of the roof material mounting body 10, install the 1.2th roof material 13, 14 from the eaves A side to the ridge B side. Raise the roof in steps. In this case, the engaging protrusion 13A formed on the back surface of the first roofing material 13 on the ridge side is engaged with the engaged portion 12A of the crosspiece 12 from the roof flow direction C, and the ridge side of the first roofing material 13 is engaged. The second roofing material 14 is superposed on the upper part, and the engaging projections 14A thereof are engaged with the engaged parts 12A, and thereafter, the same construction is sequentially carried out to raise the roof.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, the roof material mounting body 10 has a gradient in the roof flow direction C and is fixed to a roof frame (not shown). For example, a roofboard is laid on a rafter. On the upper surface of the mounting body 10, there are provided crosspieces 12 made of a long metal object extending in the longitudinal direction of the ridge with an asphalt roofing 11 interposed therebetween and having a space in the roof flow direction C, such as nailing or screwing. The crosspiece 12 has an engaged portion 12A through a front groove-shaped opening.

The engaged portion 12A has a pair of flanges 12C and 12D with the web 12B, and the eaves side flange 12C has a mounting surface portion 12F which is inclined toward the ridge side and protrudes toward the eaves side. I have. After the above-mentioned so-called groundwork construction, the roofing material is stepped up in steps from the eaves A side to the ridge B side.

Hereinafter, for convenience of description, the roof material on the side of the eaves A is defined as the first roof material 13, and the roof material on the side of the ridge B adjacent thereto is defined as the second roof material 14. The roofing materials 13 and 14 are both flat roof tiles and western roof tiles made of ceramics made of cement, silica, etc., and an engaging projection 13A that can be engaged with and disengaged from the engaged portion 12A is provided on the rear surface of the ridge. , 14 A are integrally formed, and a water receiving portion 13 B is integrally formed at the side edge portion.

The engaging protrusions 13A and 14A are unevenly distributed toward the ridge side from the eaves side edge of the upper roofing materials 13 and 14, so that the roofing materials 13 and 14 at the overlapping portion are not cracked. It is protected. Further, as shown in FIG. 2, the engaged portion 12A is lifted on the eaves side from the engaging protrusions 13A, 14A of the upper roof members 13, 14 as a base point to allow replacement of the lower roof members 13,14. The allowance 12E is provided and the flange 12D restrains further lifting.

FIG. 3 shows a second embodiment, in which a tapered portion 13C is formed to facilitate engagement of the engaging projection 13A (same for 14A) with the engaged portion 12A. FIG. 4 shows a third embodiment in which a separation preventing portion 13D is formed together with a taper portion 13C. Further, FIG. 5 shows a fourth embodiment, in which the water receiving portion 13B is engaged with the mounting surface portion 12F of the crosspiece 12 by using the clip metal fitting 15, and therefore the clip metal fitting 15 has the water receiving portion 13B. Has a first hook portion 15A for the mounting surface portion 12F and a second hook portion 15B for the mounting surface portion 12F. Others are common to the first to third embodiments.

[0013]

The present invention has been described in detail above, and the engaging projection of the roof material is disengaged from the engaged portion of the crosspiece provided to the roof material mounting body to remove the roof material. Since it is attached, the construction can be done easily and quickly compared to the conventional nailing. The engaging projections formed on the back surface of the roofing material are located on the ridge side, and the engaging projections are unevenly distributed on the ridge side and engage with the engaged parts on the roof side. While maintaining, it is possible to prevent the stepping of the overlapping part.

Further, since the upper roof material can be lifted on the eaves side because the lower roof material is replaced, the roof material can be replaced easily and quickly.
