2. Description of the Related Art In recent years, a so-called panel construction method has been widely used in which roof panels, in which a base plate is attached to a frame joined with frame materials, are attached next to a roof frame structure so as to improve roof construction workability.

[0003]

The roof of a house formed by such a panel construction method is required to be rained early so as to improve the durability of the house. There has been a strong demand for the appearance of a waterproof structure capable of waterproofing the joints formed with good workability and having excellent waterproof performance.

The present invention is based on the fact that the joint portion where the roof panels are adjacent to each other is covered with a waterproof joint tape which extends over the roof panel and is adhered to the waterproof sheet. The purpose of the invention is to provide a waterproof structure between roof panels that can be protected from rain and improve waterproofness.

[0005]

In order to achieve the above object, a waterproof structure between roof panels according to the present invention is such that a frame plate is attached to a frame structure in which frame members are joined, and a waterproof sheet is previously attached to the frame plate. The affixed roof panel is arranged adjacent to the roof frame structure, and the joints where the roof panels are adjacent to each other are covered with a waterproof joint tape that straddles the roof panel and is adhered to the waterproof sheet.

[0006]

Since the roof panel has the waterproof tape previously attached to the base plate, the waterproofing work on the upper surface of the roof panel can be made more efficient than the case where the waterproof tape is laid after the roof panel is attached.

Further, a joint portion where the roof panels are adjacent to each other is covered with a waterproof joint tape which extends over the roof panel and is adhered to the waterproof tape. Therefore, in combination with applying the waterproof tape in advance, the waterproof joint tape can be laid over the joint portion with good workability, and the rain finish can be achieved early, so that the durability of the house can be improved and the waterproof Since the joint tape is adhered to the waterproof sheet, the waterproof property at the joint can be improved and the waterproof quality without rain leakage can be secured.

Butyl rubber can be preferably used as the waterproof joint tape. Butyl rubber has excellent weather resistance and ozone resistance, and also has a relatively large adhesive strength, and can adhere to the waterproof tape made of foamed polyethylene, for example, to further improve the waterproof performance, and only to bond the waterproof joint tape to the waterproof tape. With this, it is possible to reliably perform waterproofing of joints, which is useful for labor saving on-site construction.
