BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure.

[0002]

2. Description of the Related Art A second roof on a ridge side is placed on a first roofing material on an eaves side.
Conventionally, there is a roofing structure shown in Fig. 6 as a roofing structure in which the eaves of roofing materials are overlapped and stair-shaped. In FIG. 6, a roofing material mounting body 1 shown by rafters or the like having a field board is attached to a hut set (not shown) with a roof gradient, and the roofing material mounting body 1 is attached to a first roofing material 2 on the eaves A side. The eaves side of the second roofing material 3 on the ridge side B is overlapped and stair-shaped.

[0003] That is, wooden ridges 4 are arranged on the base board at intervals in the roof flow direction C, and the wooden ridges 4 are engaged with the first and second roofing materials 2 and 3 on the ridge side. Engage projections 2A and 3A to engage nail 5
It is laid up by fastening.

[0004]

In the prior art shown in FIG. 6, when the roofing materials 2, 3 are not fixed by the nail 5, the roofing materials 2, 3 are scattered, while the nail 5, Even if it is fixed at the roof, the roof materials 2 and 3 are not fixed by the nail 5, because the eaves side of the next stage roof material is only overlapped on the ridge side of the roof material on the eaves side, There is a limit in improving the waterproof performance and the wind resistance by floating due to the wind shown by arrow D in FIG. Also, because of the nailing, it was difficult to replace the roofing material.

[0005] Therefore, the present invention is to improve the efficiency of roofing construction, while improving the wind resistance to some extent without nailing,
Moreover, it is an object of the present invention to provide a roof structure in which replacement of a roof material can be easily performed.

[0006]

Means for Solving the Problems The present invention is the first of the eaves side.
In order to achieve the above-mentioned object, the following technical measures have been taken in the roofing structure in which the eaves side of the second roofing material 14 on the ridge side is superimposed on the roofing material 13 and the roof is stair-stepped. . That is, the present invention is provided with engaging projections 13A, 14A on the back side of the ridge side of the 1.2 roofing materials 13, 14, and the engaged projections 13A, 14A are engaged with each other in a detachable manner. A crosspiece 12 having a portion 12A is provided on the roofing material mounting body 10, and the engaging projections 13A and 14A are unevenly distributed on the ridge side from the eaves edge of the upper roofing materials 13 and 14, and the first .2 The engaging projections 13A,
13B, the upper part of the roof material 13, 14 is provided on the ridge side of the ridge side, and the engaged part 12A has the upper roof material 13, 14 in order to allow the replacement of the lower roof material 13, 14. 14 engagement projections 13A,
A lifting allowable portion 12E on the eaves front side and a mounting surface portion 12F for the roofing materials 13 and 14 are provided based on 14A, and the lifting allowable portions 12E are formed by flanges 12C rising up from the eaves side to the ridge side. The surface portion 12F is formed by projecting the upper edge of the flange 12C toward the eaves side, and when the engaging portions 13A, 14A of the upper roof materials 13, 14 are fitted into the engaged portion 12A. The upper roof material 13, 14 is supported on the mounting surface 12F with a gap between the bottoms of the engaging portions 13A, 14A and the bottom 12B of the engaged portion 12A. It is assumed that.

[0007]

After mounting the beam 12 having the engaged portion 12A on the upper surface of the roof material mounting body 10 with a space in the roof flow direction, the 1.2 roof material 13 is moved from the eaves A side to the ridge B side. , 14 are sequentially laid in steps. In this case, the engaging protrusion 13A formed on the back side of the ridge side of the first roofing material 13 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 formed. The second roofing material 14 is superimposed on the upper portion, and the engaging projection 14A is
After engaging with A, the same construction will be performed and roofing will be performed in sequence.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, a roof material mounting body 10 is fixed to a hut (not shown) so as to have a gradient in a roof flow direction C. For example, a roof board is stretched on a rafter, and On the upper surface of the body 10, a beam 12 made of a long piece of metal extending in the ridge longitudinal direction with an asphalt roofing 11 interposed therebetween is fixed at intervals in the roof flow direction C, for example, by nailing, screwing, or the like. The crosspiece 12 has an engaged portion 12A through a front groove-shaped opening.

The engaged portion 12A has a web 12B and a pair of flanges 12C and 12D, and the flange 12C on the eaves side has a mounting surface 12F that is inclined toward the ridge and protrudes toward the eaves. Have. After the above-mentioned so-called groundwork is performed, the roofing material is sequentially laid in steps from the eaves A side to the ridge B side.

Hereinafter, for convenience of explanation, the roofing material on the eaves A side is defined as a first roofing material 13, and the roofing material on the building B side adjacent thereto is defined as a second roofing material 14. Roofing materials 13 and 14 are both cement,
Flat tiles, western tiles, etc., made of ceramic material made of silica or the like. Engagement projections 13A, 14A which are detachable from the engaged part 12A are integrally formed on the back side of the ridge side. A water receiving portion 13B is formed integrally with the side edge.

The engaging projections 13A and 14A are provided on the upper
3 and 14 are unevenly distributed on the ridge side from the edge of the eaves on the eaves side, thereby preventing the roof materials 13 and 14 from cracking at the overlapping part. As shown in FIG. 2, the engaged portion 12A is lifted on the eaves front side with the engagement protrusions 13A, 14A of the upper roof materials 13, 14 as a base to allow replacement of the lower roof materials 13, 14. An allowable portion 12E is provided, and the flange 12D restrains further lifting. That is, in the roofing structure according to the present invention, engaging protrusions 13A, 14A are provided on the back side of the ridge side of the 1.2 roofing materials 13, 14, and the engaging protrusions are provided.

Is unevenly distributed on the ridge side from the eaves edge of the upper roofing materials 13 and 14, and the first roofing materials 13 and 14 have upper roofs closer to the ridge side than the engaging projections 13A and 13B. There is an overlap portion of the members 13 and 14, and the engaged portion 12A has the engaging projections 13A and 14A of the upper members 13 and 14 in order to allow replacement of the lower members 13 and 14. Lifting allowable part on the eaves side with reference to 14A 12
E and a mounting surface portion 12F for roofing materials 13 and 14. The lifting allowable portion 12E is formed by a flange 12C which rises from the eaves side to the ridge side, and the mounting surface portion 12F is
C is formed by projecting the upper edge of the upper roof member C toward the eaves, and the engaging portions 13A, 14A of the roof members 13, 14 in the upper stage are formed.
Is fitted into the engaged portion 12A, the engaging portions 13A, 14
The roof members 13 and 14 in the upper stage are supported on the mounting surface 12F in a state where there is a gap between the bottom of A and the bottom 12B of the engaged portion 12A.

FIG. 3 shows a second embodiment, in which an engagement projection 13A is provided.
(The same applies to 14A). A tapered portion 13C is formed to facilitate engagement with the engaged portion 12A. FIG. 4 shows a third embodiment, in which the tapered portion 13C and the detachment preventing portion 13D are formed together with the tapered portion 13C. Is formed. 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 using the clip metal 15, so that the clip metal 15 is provided on the water receiving portion 13B.
