DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure and an outfitted roof panel for ensuring the waterproofness of a building roof surface.

[0002]

2. Description of the Related Art In recent years, the construction of houses has been industrialized. For example, components such as walls, floors, and roofs have been panelized in factories in advance, and these panels have been assembled at a construction site to construct a house. Some panel construction methods have been adopted.

When a house is constructed by the above-described panel construction method, a roof panel laid on the roof surface of the house is constructed by assembling two vertical frame members and two horizontal frame members into a rectangular shape. The frame is formed by assembling reinforcing bars inside the rectangular frame, and a face material such as plywood is attached to one surface of the frame.

When a roof 100 of a building as shown in FIG. 5 is constructed using this roof panel, for example, as shown in Japanese Patent Application Laid-Open No. 6-129059, “Roof Panel”, At the top of the structure of the building, a roof-supported shed composed of a plurality of beams is constructed. Then, the roof panel 101 is arranged on the hut set, and the roof panel 10
The roof panel 101 is fixed on the hut set by joining one end to the beams forming the hut set and the wall 102 of the building. Next, in order to maintain the waterproofness of the roof 100, a roofing material 103 such as an asphalt roofing is provided on the upper surface of the roof panel 101 in a direction perpendicular to the gradient direction of the roof and at an end of the adjacent roofing material 103. Lay the parts so that they overlap each other. Then, the roofing material 103 is fixed to the roof panel by nailing with a tacker or the like, and a roof finishing material (not shown) is attached to an upper surface of the roofing material 103, whereby the building roof 100 is constructed.

However, in the above-described roofing material laying work, usually, a roofing material wound in a roll shape is positioned on a roof surface, and then deployed and laid in a direction orthogonal to the gradient direction of the roof. Therefore, the work is performed on the site where the scaffold is unstable. In addition, asphalt roofing materials are heavy and have low strength against tensile and shear forces, so that care must be taken when using them. For the reasons described above, the work of laying roofing material on the roof surface causes a delay in house construction work on site.

In order to solve the above-mentioned problem, as shown in FIG. 6, a roofing material 104 is cut in advance in a factory or the like so that the roofing material 105 has substantially the same shape as the upper surface of the roof panel 105. Roof panel 10
5 is stuck on the upper surface. And the roof panel 105
Is transported to the site and placed on the hut. Then, a method has been proposed in which a waterproof tape 106 is attached vertically and horizontally along the joint portion of each roof panel 105 in order to ensure waterproofness at the joint portion between the roof panels 105.
