DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the accompanying drawings. As shown in FIG. 1, a hut set 8 of a building 7 includes a roof beam 2 for supporting a roof, and a hut bundle 9.
And a purlin 3. As the roof beams 2, there are a roof beam 2b on the ridge side and a roof beam 2a on the eaves side, which are arranged below and adjacent to both sides of the ridge. The shed bundle 9 is erected on the roof beam 2b on the ridge side, and the purlin 3 is mounted and fixed on the shed bundle 9 in parallel with the roof beam 2b on the ridge side. As the purlins 3 used in the present invention, there are only two purlins 3 provided close to each other with this ridge therebetween.
Also, purlins are not required in the present invention. On the purlin 3, a supporting material 4 bent in a square wave shape along the uneven shape of the back surface of the folded-plate roofing material 1 is mounted and fixed. Further, a support member 4 bent in a similar square wave shape is mounted and fixed on the roof beam 2a on the eaves side. In the embodiment, the length from the ridge to the eaves is 3600 mm.

The folded sheet roof material 1 is formed by bending a metal plate, and a 0.8 mm thick metal plate is used. Incidentally, the conventional folded plate roofing material 1 is 0.6 mm thick. This folded-plate roofing material 1 has one end mounted on and supported by a supporting material 4 provided on a roof beam 2a on the eaves side, and the other end of a supporting material 4 provided on a purlin 3 near the ridge. It is mounted and supported on top. Here, the folded-plate roofing material 1 is constructed so that the roof slope becomes a two-dimension slope. For this reason, the above-mentioned hut set 8 becomes a cottage set for a two-dimension roof slope, and the hut bundle 9 is also short. used. Since the roof slope is gentle and the thickness of the folded roof material 1 is 0.8 mm, which is thicker than before, the span length for supporting the folded roof material 1 in the wife direction can be increased. Even if the folded-plate roofing material 1 attached in an inclined state with the ridge therebetween is supported and fixed by the roof beam 2a on the eaves side and the support member 4 attached to the purlin 3 provided close to the ridge. , So that it can be sufficiently supported.
By the way, conventionally, since the thickness of the folded sheet roofing material 1 is 0.6 mm and the roof slope is a steep slope of 4 dimensions, the pitch of the shed bundle is required to be 1800 mm in the wife direction, and the folded sheet roofing material in the wife direction is required. 1800mm spacing between parts supporting 1
However, according to the present invention, the interval between the portions supporting the folded-plate roofing material 1 in the direction of the wife is nearly twice as large as that in the related art.

[0010] In the embodiment shown in the figure, an example of an apartment is shown as the building 7, and a part of the front side of the building 7 is recessed. Is located between the roof beam 2a on the ridge side and the main building 3 on the ridge side. The lower space sandwiched between the roof beam 2a on the eaves side and the main building 3 on the ridge side is a space 5 for stairs, and a space 5 for stairs. Steps 11 are formed as shown in FIGS. The stairs space 5 in which the stairs 11 are formed can enter and exit from the entrance of each dwelling unit 12 of the apartment. That is, in the embodiment shown in the drawing, two units are provided on the first floor of the building 7 constituting the apartment, and two dwelling units 12 are provided on the second floor, and the entrance door 1 of each dwelling unit 12 is provided.
3 is provided facing the space 5 for the stairs, and the entrance door 13
The stairs 11 are formed from each dwelling unit 12 to enter and exit the stair space 5, and from the stair space 5, it is possible to enter and exit outdoors. In the figure, reference numeral 16 denotes a partition wall that separates the staircase space 5 from the outside.

As described above, the lower space sandwiched between the roof beam 2a on the eaves side and the main house 3 on the ridge side is a space 5 for stairs, so that the folded sheet roof material 1 constitutes the ceiling of the space 5 for stairs. Will do. Here, since the roof beams do not cross the ceiling portion or the shed bundle is not exposed, the appearance can be improved, and the folded plate roofing material 1 itself can be used as the ceiling, so that the ceiling height can be reduced. Can be higher.

In the above embodiment, the lower space between the roof beam 2a on the eaves side and the main house 3 on the ridge side is a space for stairs 5
However, it is also possible to form a blow-through space in the lower space between the roof beam 2a on the eaves side and the main house 3 on the ridge side. By the way , in the present invention, the main house 3 is arranged with the building interposed therebetween, and the upper ends of the folded sheet roofing material 1 on both sides are supported by the main buildings 3 on both sides arranged with the building interposed therebetween. It does not require a purlin as in the past. Thus, by adopting a configuration that does not use the purlin, it becomes possible to perform the ventilating without being disturbed by the purlin as in the related art when performing the ventilation using the ridge part.

In the figure, reference numeral 15 denotes a horizontal member, on which the shed bundle 9 is erected or the folded roof member 1 is not directly supported. In the above-described embodiment, an example of an apartment is shown as the building 7, but it is a matter of course that the present invention is not necessarily limited to an apartment.

[0014]

According to the present invention , a folded-plate roofing material which is mounted in an inclined state with the building interposed therebetween is mounted on the roof beam on the eaves side and on the main roof which is provided adjacent to the building with the building interposed therebetween. It is supported and fixed with support materials and sandwiched between the roof beam on the eaves side and the main building on the ridge side.
The lower part of the space is a space for stairs, so the folded-plate roofing material can be installed with a simple configuration that only supports it with the roof beam on the eaves side and the main building provided near the ridge, as a result, it does not take construction effort, all SANYO possible to reduce the cost and sandwiched by haze eaves side of the roof beams and ridge side
There is a space for stairs in the lower part of the open space.
There is another roof beam or hut bundle between the root beam and the main building on the ridge side
