Beams 8 are arranged on the upper surfaces of both sides of the floor plate 6, and the L-shaped portions 10 a of the mounting brackets 10 are fixed to the beams 8 at regular intervals by nails. Multiple mounting brackets 1
Of the mounting brackets 0, the mounting bracket 10 located on the column 2 has its vertical portion 10b fixed to the corresponding column 2 with a nail. In the center (ridge) of the upper part of the building, a beam support 12 is horizontally arranged along the axis of the ridge of the building, and both ends thereof are supported by columns 14 erected on the floor plate 6. 16,18
Are C-shaped steels whose side surfaces are overlapped with each other, and are fixed on the beam receiver 12.

Numeral 20 denotes a plurality of C-shaped steels arranged in parallel with each other, which are bent in a bow shape, one of which is fixed to a curved support portion 10c of a corresponding mounting bracket 10 by bolts and nuts. I have. The other of each of the C-section steels 20 is supported by the C-section steel 16. Reference numeral 22 denotes a plurality of C-shaped steels arranged in parallel with each other, and is formed in the same shape as the C-shaped steel 20. Each of the C-shaped steel members 22 is disposed to face the corresponding one of the corresponding C-shaped steel members 20, and one of the C-shaped steel members 22 is fixed to the curved support portion 10c of the corresponding mounting bracket 10 by bolts and nuts.

The other of each of the C-shaped steels 22 is supported by the C-shaped steel 18. A plurality of band irons 24 are wound around the C-shaped steels 20 arranged in parallel at right angles, and are each fixed to the C-shaped steels 20. Similarly, C arranged in parallel
A plurality of band irons 24 are also laid on the section steel 22 in the perpendicular direction, and are each fixed to the section C steel 22. Each of the C-shaped steels 20, 22 is disposed with the open side facing upward. An iron plate 26 is laid on the band iron 24, and a gypsum board 28 is laid on the iron plate 26.

On the gypsum board 28, a waterproof sheet 30 is placed.
Is laid, and a metal roof plate 32 is mounted on the waterproof sheet 30. The mounting structure of the shingle 32
As shown in FIG. 3, the gutter 3 in which the engagement portion 34a is formed
4 is arranged in the groove of the gypsum board 28, and the gutter 34 is fixed to the gypsum board 28. The side portions of the pair of shingles 32, 32 are arranged on the gutter 34, and the engagement portions 3 of the gutter 34
The engaging portion of the joiner 36 is fitted to 4a, and the side portions of the roof plates 32, 32 are supported by the joiner 36.

The C-shaped steels 16 and 18 constitute a receiving member, and a T-shaped portion 38 is formed on the upper portion of the receiving member along the ridge of the building. The T-shaped portion 38 has a substantially U-shaped cross section. A cover member 40 made of a long metal plate is fitted and arranged. 4
2 is a ceiling decorative board made of gypsum board;
It is fixed to the bottom of the shape steels 20,22. The ceiling decorative board 42 has a large number of small holes for ventilation. A heat insulating material 44 such as glass wool or urethane foam is filled between the C-shaped steels 20 and 22. An exhaust passage 46 surrounded by the T-shaped portion 38 and the cover 40 is formed in the ridge of the building, and both ends of the exhaust passage 46 in the direction perpendicular to the paper of FIG. 1 communicate with the outside air. The exhaust passage 46

In the above construction, the air inside the building is guided to the exhaust passage 46 through the small holes in the ceiling board 42 and the gap between the C-shaped steels 20 and 22, and is discharged to the outside air. still,
Instead of using a configuration in which the C-shaped steel members 20 and 22 are abutted on the ridge of the building, as shown in FIG. 5, a plurality of C-shaped steel members 48 bent into a semicircle extending from one eave of the building to the other eave are used. A circular roof may be configured.

The vicinity of both ends of the C-shaped steel 48 is supported by the beam 8 via the mounting bracket 10. A pair of shingles 32, 32
In the ridge portion, rising portions 32a, 32a are formed in an L shape at the ridge portion, and the cover 40 is fitted to these rising portions 32a, 32a. In FIG. 5, an air passage extending vertically along the ridge in FIG. 5 and surrounded by the cover 40 and the rising portions 32 a of the roof plates 32 constitutes an exhaust passage 46. The exhaust path 46 communicates with the lower surface of the iron plate 26, and both ends in the direction perpendicular to the paper of FIG. 5 communicate with the outside air. Other configurations are the same as those of the embodiment shown in FIG.

[0012]

According to the present invention, as described above, since the C-shaped steel is used as the aggregate of the round roof, the manufacturing cost can be reduced, and the exhaust passage is formed in the wing of the round roof, so that the indoor space is formed. This has the effect of keeping the air clean.
