BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertically-roofed roof structure in which an air layer is provided on the back side of a roof plate.

[0002]

2. Description of the Related Art An air layer is provided directly under a roof plate or on the backside of a roof substrate to cope with the increase in functions required for the roof structure of buildings such as ventilation of the attic and storage of heat by solar heat energy. A roof structure has been proposed. As a roof structure having such an air layer, there is a roof structure disclosed in Japanese Utility Model Laid-Open No. 2-89127 and Japanese Utility Model Laid-Open No. 49-8152.
The one disclosed in Japanese Patent No. 2 is known.

However, in the one disclosed in Japanese Utility Model Laid-Open No. 2-89127, an air layer and a heat insulating layer are formed between the ground plate and the roof plate of a building, but for that purpose, a special special shape is used. Since the existing roofing board, heat insulating material and space forming member are used, in other words, there is a problem that the cost becomes high because the existing vertical roofing board or the like cannot be used for construction.

In Japanese Utility Model Application Laid-Open No. 49-81522, a space is provided between a roof plate and a main board by interposing a reinforcing material corresponding to a wooden rafter. According to the structure, since there is no means to support the entire back surface of the roof above the space, it is necessary to arrange a number of reinforcing materials in the vertical direction at narrow intervals as shown in order to meet the strength requirement of the roof surface. However, particularly when trying to apply a wide roof plate, a large number of reinforcing materials are required, so that there is a drawback that not only the cost of parts becomes high but also construction is troublesome.

By applying the one that forms the step part that holds the edge of the base material, the roof plate can be directly supported by the support member without the outer base material, so that the support strength of the roof plate is reduced. Be advantageous.

Further, as the supporting member, a lower member having a flange portion for seating on the inner base material is formed at the lower end of the side wall portion having a predetermined height hanging from both ends of the top portion, and a shape which can be superposed on the lower member from above. And a side part hanging from both ends of the receiving part that overlaps with the top part of the lower member and supports the roof plate, and is positioned a predetermined height above the flange part to support the end part of the outer base material. You may make it apply what consists of the upper member which formed the shelf part. According to this support member, the plate thickness of each of the upper and lower members is reduced to reduce the weight and save the material, and at the same time, the plate thickness is secured in the receiving portion for supporting the roof plate by the overlapping structure so that the fixing screws, etc. It is possible to secure a sufficient fixing force for the. In addition, the thickness of the air layer can be selected according to the height of the side wall of the lower member, and the thickness of the outer base material can be selected according to the height of the side of the upper member. It is highly versatile that you can set different specifications.

On the other hand, by arranging the allocating means corresponding to the effective width of the roof plate along the longitudinal direction of the receiving portion of the supporting member, the roof plate can be allocated by the supporting member itself. Therefore, the workability of roof construction is greatly improved.
