Description

Description: TECHNICAL FIELD The present invention relates to a roof structure for the convenience of forming a roof covering a staircase adjacent to an outer peripheral wall in a building, particularly a housing complex.

[Problems to be Solved by Prior Art and Invention]

In recent years, in buildings, especially multi-storey apartments,
Stairs are often provided adjacent to the outer peripheral wall of the house.
Also, such stairs are often formed as open steps without roof.

However, with the recent preference for luxury houses, it is required to provide a roof on the stairs of such an apartment house.

On the other hand, in such an apartment house, a so-called folded roof, in which a steel plate is bent in a mountain wave shape, is often used.

In particular, in the stairs provided on the outer peripheral wall of such an apartment house, the present invention extends a pillar that receives the stairs upward, and supports an overhang portion of a folded roof for forming a roof of a house body above the stairs. Based on the above, it is an object of the present invention to provide a roof structure which can form a roof covering the stairs conveniently and can meet the above demand.

[Means for solving the problem]

The present invention is a roof structure for forming a roof covering a step provided on the outer side of an outer peripheral wall of a house main body using a staircase roof frame structure and a folded roof, wherein the staircase roof frame structure is An outer frame body which is provided outside the stairs and along the stairs, and which supports the stairs and extends to the vicinity of the roof height of the main body of the house, and an outer frame body including a stair beam connecting between upper ends of the pillars, A support beam horizontally arranged along the wall, and a roof beam formed by using a shaped steel material having horizontal flanges at the upper and lower ends of the web and connecting between the outer frame and the support beam, The roof beam is located on the staircase roof structure by locating the upper flange at a height in the vicinity of the upper end of the outer peripheral wall, from the main roof made of the folded roof and covering the main body of the house to the staircase. Overhang Overhang that covers the stairs In addition to arranging the parts, a joint metal fitting, which constitutes the ceiling of the staircase and whose one end is in contact with the outer surface of the outer peripheral wall, is fixed at the lower end to the flange below the roof beam. It is attached by wedging.

[Action]

The pillars that support the stairs extend near the roof height of the main body of the house. Further, the stair roof frame structure is formed by an outer frame body consisting of this column and a step column connecting the upper ends thereof, a support beam arranged along the outer peripheral wall, and a roof beam connecting the outer frame body and the support beam. . In addition, a stair roof is formed by arranging a projecting portion which is a folded roof and extends over the stair from the main roof that covers the main body of the house in this stair roof structure. Therefore, the roof above the stairs can be easily formed, and can be conveniently used for forming a roof for covering the stairs adjacent to the outer peripheral wall of the apartment, in particular.

Proper joints are provided on each folded roof S of, and further front and rear pillars 2
It can be modified in various ways, such as by providing a wall between A and 2B.

〔The invention's effect〕

As described above, the roof structure of the present invention includes an outer frame body including a column extending to the vicinity of the roof height of the house body and a staircase column connecting the upper ends thereof, a support beam arranged along the outer peripheral wall, and the outer frame. On the staircase roof frame structure that connects the body and the supporting beam and the upper flange is formed by the roof beam located at the height near the upper end of the outer peripheral wall, from the main roof consisting of the folded roof covering the main body of the house to the stairs Since the roof of the stairs is formed by arranging the overhanging parts, it becomes possible to form the roof of the stairs that is continuous with the main roof by a series of continuous folded roofs. Facilitates formation,
The workability can be improved, and the overhanging portion can be firmly fixed to the flange on the roof beam via, for example, a mountain-shaped support fitting, which enhances the roof strength and helps improve the quality of construction. In particular, it can be conveniently used in a housing complex to form a roof covering the steps adjacent to the outer peripheral wall thereof. In addition, a notch of a joint fitting that fixes the ceiling material is wedged to the flange under the roof beam, so that the ceiling of the staircase can be formed easily or at the same time, and one end of the ceiling material is the outer periphery. Since it contacts the outer surface of the wall, the joint treatment at the one end can be simplified and the construction efficiency can be improved.
