Abstract

PURPOSE:To improve the workability by arranging first and second-roof panels manufactured in a factory respectively on roof faces on the steep gradient side and the gentle gradient side, and fitting a mansard drain board to the adjoining part of both panels so as to be continuously laid over them. CONSTITUTION:A first roof panel 1 manufactured in a factory and constituted of rafters 11, a sheathing roof board 17, a waterproof sheet 13, and roof tiles 12 is fitted to a roof face on the steep gradient side. Next a second roof panel 2 constituted of rafters 21, a sheathing roof board 27, and a waterproof sheet 23, is fitted to a roof face on the gentle gradient side adjacent to the panel 1. Next after the mansard drain board 10 is fitted to the adjoining part of panels 1, 2 so as to be continuously laid over them, roof tiles 22 arc roofed on the sheet 23. If necessary, the sheet 23 is placed on the sheet 13 or the drain board 10 so as to improve the waterproofness. In addition, draining bars 16 are provided between the sheet 13 and the roof tiles 12 so as to prevent the roof tiles 12 from being peeled off by a wind or the like. Hereby, this construction can be executed simply and safely, the construction period can be shortened, and the waterproofness can be improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waist-folded roof structure and a method of constructing the same, and is useful, for example, for a roof whose roof surface is folded in the middle, a lower portion has a steep slope and an upper portion has a gentle slope. Waist folded roof structure and its construction method.

[0002]

2. Description of the Related Art Conventionally, various roof structures using roof panels have been proposed. For example, as disclosed in Japanese Unexamined Patent Publication No. 5-230949, roof panels to which a large number of roof materials have been attached in advance are continuously arranged in the roof slope direction, and a connecting roof material is inserted under the roof material of the upper roof panel. These roofing materials are nailed through the waterproof patches placed between them and secured to the roof panels. The connected roofing material has its upper end located below the roofing material of the upper roof panel and its lower end located above the roofing material of the lower roof panel, thus maintaining continuity with other roofing materials. The joints are not conspicuous, rainwater and the like do not sequentially flow over the roofing material and leak, and the joints are reliably waterproofed.

[0003]

However, in the roof structure as described above, the construction on site is simple and can be carried out in a short period of time, but the roof slope where the lower roof panel and the upper roof panel are arranged is different. In the so-called waist-folded roof structure, even if the connecting roof material is inserted under the roof material of the upper roof panel, the connecting roof material cannot cope with the roof slope, so that there is a problem that sufficient waterproofing cannot be achieved.

The present invention has been made in view of the above facts, and an object of the present invention is to improve the waterproof performance even if the roof panel and the roof slope on which the roof panels are arranged are different. An object is to provide a waist-folded roof structure that can be easily installed while being held and can be installed in a short period of time.
