Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure having a roof surface forming a part of a pitched roof. Specifically, the present invention relates to a roof structure such as a roof panel or a roof unit manufactured in a factory.

[0002]

BACKGROUND ART Conventionally, a roof structure having a roof surface forming a part of a pitched roof, for example, a roof panel or a roof unit, has a field plate attached to a panel frame or a unit frame in a factory. The roofing for waterproofing is laid on the above in the direction orthogonal to the gradient direction, and so as to partially overlap each other in the gradient direction,
It is manufactured by driving nails 4 such as tacker from above to fix the roofing 3 to the base plate 2 and then attaching a roof finishing material on the roofing plate 2 leaving the connection end.

In order to build a building such as a house using such a panel or unit, a roof panel or roof unit manufactured in a factory is transported to a construction site together with a box-shaped living room unit, and the living room unit is constructed at the construction site. After building the building body by combining them, the roof panels and roof units are hung on top of them to create a roof. At this time, the connection work between the adjacent roof panels and roof units, the roofing for connection is overlapped over the connection ends of the adjacent roof panels and roof units,
After fixing nails such as tackers to the roofing board to fix it to the base plate, a roof finishing material for joints is mounted on it.

[0004]

According to the conventional roof construction method, when a roof panel or roof unit is hung and combined on a building body to make a roof at a construction site, a connecting end of an adjacent roof panel or roof unit is used. Since it is necessary to overlap the roofing for connecting across the sections and fix both sides to the adjacent roof panel or roof unit, there is a lot of work at the construction site and it took time to construct. Moreover, in order to stack the roofing 3 over the connecting end of the adjacent roof panel or roof unit, that is,
Since the structure is such that rainwater may enter from both ends of the roof for connection, it took time for waterproofing.

An object of the present invention is to solve all of the above-mentioned conventional drawbacks, to provide a roof structure having a structure capable of facilitating connection work at a construction site and having little possibility of rainwater intrusion. It is in.

[0006]

Therefore, the roof structure of the present invention is a roof structure having a roof surface forming a part of a pitched roof, and the roof surface is provided with a roofing, and It is characterized in that the roofing is projected from at least one side end of a direction of the roof surface which is orthogonal to the gradient direction out of the gradient direction and the direction orthogonal to the gradient direction.

Here, an adhesive may be provided on the back surface of the protruding portion of the roofing or on the surface of the end portion opposite to the protruding portion of the roofing. Further, the adhesive is
A plurality of linear or band-shaped materials may be provided, and the material may be asphalt. Furthermore, the release sheet may be releasably adhered along the portion where the adhesive is provided.

[0008]

According to the roof construction of the present invention, the roofing is projected from at least one side end of the slope direction of the roof surface and the direction orthogonal to the slope direction at least in the direction orthogonal to the slope direction. Therefore, at the construction site, after arranging a plurality of roof structures adjacent to each other, the roofing projecting from one side end side may be overlapped and connected on the roofing of the adjacent roof structure, that is, one side of the roofing. Since only the connection work of is required, the connection work at the construction site can be easily performed, and the structure in which the possibility of infiltration of rainwater can be reduced.

At this time, if the adhesive is provided on the back surface of the roofing protrusion or on the surface of the end opposite to the roofing protrusion, the connection work can be performed more easily and quickly. In particular, if an adhesive is provided on the surface of the end portion on the side opposite to the protruding portion of the roofing, the surface becomes the surface side, which facilitates connection work and prevents rainwater from entering more reliably.

Further, when a plurality of adhesives are provided in a linear or strip shape, the fixing to the roof surface and the connection of the roofing can be surely performed with a small amount of the adhesive, and the roofing can be connected to each other. It is possible to reliably prevent the intrusion of rainwater from the overlapping parts.

Further, if the adhesive is composed of asphalt mixed with synthetic rubber or natural rubber, the adhesive performance increases with time, and as a result, inexpensive and reliable waterproofing effect can be expected. Furthermore, if the release sheet is releasably adhered along the portion where the adhesive is provided, the roofing is wound in a roll, or
Can be stored and transported in a stacked state.
