Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure of a double-sloped roof such as a parquet type or a gable type, and can be used when forming a space in a roof for a living room or the like inside the roof.

[0002]

BACKGROUND ART FIG. 4 shows a roof 90 which is an example of a conventional roof structure. The roof 90 has a divided structure of a roof central portion 91 having a substantially trapezoidal cross section and a roof end portion 92 having a substantially triangular cross section arranged on both sides (girder side) so as to sandwich the roof central portion 91,
The roof surface 93 is divided into an upper roof surface 94 and a lower roof surface 95. The roof center part 91 and the roof end part 92 may be formed as a unit or may be formed by panels. Further, the roof central portion 91 is generally formed by further dividing only the upper mountain portion.

After the roof 90 is assembled, the roof center portion 91 and the roof end portion 92 are bounded by each other (indicated by a dotted line A in the figure).
Part) and is supported by bundles 96 and 97 provided respectively. In addition, one of these bundles 96 and 97 is provided, and the bundle may be shared by the roof center portion 91 and the roof end portion 92. In either case, the roof center 91 and the roof edge 92 are supported by the bundles 96 and / or the bundles 97 at their boundaries.

[0004]

However, in the structure of the conventional roof 90 as described above, the roof center portion 91 and the roof end portion 92 are bundled 96 at their boundary portions (A portions indicated by dotted lines in the figure).
And / or roof 90 as supported by bundle 97
When a roof space such as a room is to be formed inside the room, design restrictions can be imposed by the existence of such bundles 96 and 97, and the degree of freedom in the floor space including the door arrangement etc. There was a problem that it decreased. For example, when partitioning the space in the roof into two or more sections in the girder direction, bundles 96, 97
It is possible to form a partition wall at the position where the partition wall is arranged along the gable direction, but if an opening for a passage is provided in this partition wall to connect each partitioned partition, the openings are bundled.
6 and 97 should be provided so that, considering the length and width required for the openings, the openings are provided between the bundles 96 and 97, that is, the roof central portion 91 and the roof end portions 92 on both sides. It must be provided between the respective boundary portions (part A of the dotted line in the figure) between and. Therefore, when the stairs 98 from the lower floor to the space inside the roof are provided adjacent to each other along the partition wall as shown by the chain double-dashed line in the figure, the end portion B where the stairs 98 have finished climbing
There is a problem that a waste of space is great because it is necessary to form a passage that wraps around from the position of No. 2 to the opening provided between the bundles 96 and 97.

An object of the present invention is to provide a roof structure capable of reliably supporting the roof surface and effectively utilizing the space inside the roof.

[0006]

[0007]

In the present invention as described above, the upper roof surface and the lower roof surface divided along the girder direction are joined at the receiving portion to form one roof surface. This joining is performed on both sides of the ridgeline, and the receiving portions on both sides are supported by both ends of the beam extending in the gable direction . And this beam is supported by a pillar in the middle part,
These support the roof. At this time, the pillar is not limited to the position immediately below the joint between the upper roof surface and the lower roof surface as in the conventional bundles 96 and 97 described above, and it can be located anywhere in the middle of the beam. Since it can be provided in the above, the degree of freedom in design is improved. Especially, when a partition wall for partitioning the space inside the roof as described above is provided, it is possible to provide an opening on the outside of the pillar, that is, on the end side of the partition wall by incorporating the pillar in the middle part of this partition wall. Becomes In other words, if the pillar is located inside the position just below the joint between the upper roof surface and the lower roof surface (the position of the conventional bundles 96, 97), the outside of the pillar will have the length required for the passage opening. And width are secured sufficiently. This eliminates the waste of space associated with the installation of the stairs 98 as described above.

Further, when the upper roof surface and the lower roof surface are further divided along the gable direction, each upper side is located at the position where the dividing line along the girder direction and the dividing line along the gable direction intersect. If the roof surface and the four end portions of each lower roof surface are received together by the receiving part, it is not necessary to install double columns or beams at the dividing line along the gable direction. The number of members for joining and supporting is reduced to simplify the assembling work and reduce the cost, and the effective use of the space in the roof is achieved, thereby achieving the above object.
