It is configured. The pair of trapezoidal roof surfaces 8 are positioned with their ridge sides facing each other and are continuous with each other. The pair of triangular roof surfaces 8 are positioned with their ridge sides facing each other and are positioned with a distance from each other.

The four roof surfaces 8 described above have the following common configuration. That is, each roof surface 8 has two inclined sides 81 and 82 located on both left and right sides and an eaves side 85 (see FIGS. 2 and 3). The two inclined sides 81 and 82 are inclined so that the distance between them increases from the ridge side toward the eaves side, and both inclined sides 81 and 82 intersect the eaves side 85 at an acute angle. The two inclined sides 81 and 82 are a pair of corner sides positioned opposite to each other. The above shape of the roof surface 8 is only an example and it is also possible to have other shapes.

A plurality of roofing materials 1 includes a plurality of standard roofing materials 2 occupying the main portion thereof and a plurality of adjusting roofing materials 3 different from the plurality of standard roofing materials 2. - 特許庁In the roof structure 9 of the first embodiment, these standard roof materials 2 and adjustment roof materials 3 are allocated to the roof surface 8 .

In the first embodiment, among the plurality of standard roofing materials 2 arranged side by side in the left-right direction on each stage, at least the standard roofing materials 2 positioned at both left and right ends are pre-cut materials 2b.

These plurality of standard roofing materials 2 (ordinary materials 2a and precut materials 2b for each stage) are ridged on the roof surface 8 so as to have a constant working width (that is, the eaves ridge direction dimension of the portion exposed to the outside) W2. They are assigned in order from the side to the eaves side. The working width W2 is the width dimension in the eaves ridge direction D1 (D2) of a portion of each standard roofing material 2 that does not overlap another standard roofing material 2 placed on the upper stage. The order of allocation of the plurality of standard roofing materials 2 in the first embodiment is opposite to that in the prior art. It should be noted that the constant working width in this specification does not require strict uniformity, and may be of a degree that can be regarded as a constant working width in the field of building materials.

The plurality of standard roofing materials 2 include the standard roofing material 2 arranged closest to the ridge (hereinafter referred to as "ridge end roofing material 2R") among the plurality of standard roofing materials 2, and the plurality of standard roofing materials 2. Among them, the standard roofing material 2 arranged closest to the eaves (hereinafter referred to as "edge roofing material 2E") is included. In the first embodiment, the ridge end roofing material 2R is the roofing material 1 closest to the ridge among the plurality of roofing materials 1 .

On the trapezoidal roof surface 8, two ridge end roof materials 2R aligned laterally are constituted by two trapezoidal precut materials 2b aligned laterally. Moreover, the four eaves roof materials 2E arranged horizontally are composed of precut materials 2b at both left and right ends and two normal materials 2a positioned between the precut materials 2b at both ends.

On the triangular roof surface 8, one ridge end roof material 2R is composed of one triangular precut material 2b. The four eaves roof materials 2E aligned in the left and right are composed of pre-cut materials 2b on both left and right ends and two normal materials 2a positioned between the pre-cut materials 2b on both ends.

A plurality of adjustment roof materials 3 are allocated to the eaves side of the plurality of standard roof materials 2. - 特許庁In other words, in the roof structure 9 of the first embodiment, a plurality of adjustment roof materials 3 arranged laterally are allocated further to the eave side of a plurality of eaves edge roof materials 2E arranged laterally.

The width dimension in the eaves ridge direction D1 (D2) of each adjustment roof material 3 is set shorter than the width dimension in the eaves ridge direction D1 (D2) of each standard roof material 2 (see FIG. 4).

The plurality of adjustment roof materials 3 include normal adjustment materials 3a that are not precut and precut adjustment materials 3b that are precut. The normal adjustment member 3a has a flat plate shape and a rectangular shape in a plan view. The normal adjustment member 3a has a point-symmetrical shape. That is, the normal adjustment member 3a has the same shape as before rotation when rotated 180° about an axis passing through its center and parallel to the thickness direction.

The pre-cut adjusting material 3b has a right-angled corner portion 31 and an inclined side portion 32 located on the opposite side of the corner portion 31. As shown in FIG. The inclined side portion 32 is a side formed by precutting. The inclined side portion 32 of each precut adjustment member 3b is arranged along one of the left and right inclined sides 81 and 82 of the roof surface 8 when the precut adjustment member 3b is installed at the eaves end portion of the roof surface 8. is set. Of the plurality of adjusting roof materials 3 arranged side by side in the left-right direction, the adjusting roof materials 3 positioned at both left and right ends are pre-cut adjusting materials 3b.

Allocation of these plurality of roof materials 3 for adjustment (regular adjustment materials 3a and precut adjustment materials 3b) is performed by allocating the plurality of standard roof materials 2 in order from the ridge side to the eaves side, and then covering the eaves end of the roof surface 8. It is done as follows.

On the trapezoidal roof surface 8, the five adjustment roof materials 3 aligned left and right are arranged between the pre-cut adjustment materials 3b at both left and right ends, and the three normal adjustment materials positioned side by side between the pre-cut adjustment materials 3b at both ends. 3a.

The roof surface 8 is allocated in order from the ridge side to the eaves side so as to have the width, and then a plurality of adjusting roof materials 3 are allocated further to the eaves side of the eaves edge roof material 2E.

According to this method, the size and shape of each adjustment roof material 3 can be adjusted according to the lateral dimension of the eaves of the roof surface 8, and the cut shape of the standard roof material 2 need not be set for each building. good too. That is, for each precut material 2b hatched in a lattice pattern in FIG. Therefore, there is a first advantage that the roof structure 9 can be constructed using the pre-cut material 2b having a standardized cut shape even if the target building is different.

In addition, the roof structure 9 of the first embodiment has a second advantage that the ridge end roof material 2R can be directly fixed to the roof surface 8 without intervening offcuts ( See Figure 5). A coping 41 is placed on the ridge-side end of the ridge-end roofing material 2R, and a fixture 43 that penetrates the coping 41 and the ridge-end roofing material 2R consistently is driven into the roof surface 8 to form a ridge-end roof. The material 2R is fixed to the roof surface 8. In addition to the coping 41 and the ridge end roof material 2R, the fixture 43 consistently penetrates the standard roof material 2 on the stage below the ridge end roof material 2R. The ridge end roof material 2R and the standard roof material 2 on the lower stage are also fixed to the roof surface 8 by another fixture 44. - 特許庁The coping 41 is covered with a ridge wrap 45 , and the coping 41 and the ridge wrap 45 are fixed with fixtures 47 . In the first embodiment, the fixtures 43, 44, 47 are nails.

Therefore, there is no need to adjust the gap with scrap materials at the ridge-side end of the roof structure 9, and the labor of packing and shipping the scrap materials is unnecessary. In addition, it is possible to suppress the generation of waste materials on site due to the shipping of offcuts.

Also in the roof structure 9 as described above, there are cases where it is preferable to arrange offcuts for various reasons (for example, offcuts between the ridge-side end of the ridge end roof material 2R and the roof surface 8). is not arranged, the eaves-side end of the ridge roof material 2R may float above the proper position).

In such a case, as an example is shown in FIG. 9, a residual material 305 produced by cutting a portion of the precut adjustment material 3b along the inclined sides 81 and 82 for size matching on site is used as a scrap material. It can also be used as It is also possible to use the leftover material 105 produced by cutting the portions along the inclined sides 81 and 82 of the starter 10 laid along the eaves 85 for on-site size matching as offcuts. .

According to this method, basically, the ridge end roof material 2R can be fixed to the roof surface 8 without intervening offcuts. Either of the remaining materials 105 and 305 can be used as offcuts. Therefore, it is not necessary to pack and ship offcuts in order to prevent the eaves-side end of the ridge roof material 2R from floating upward.
