However, in the above-described conventional thatched roof, for example, the one described in the first example, an air layer and a heat insulating layer are provided between the base plate on the main roof and the galvanized iron roof plate. Since it is formed in the vertical direction, it is necessary to separately manufacture and use a roof plate having a special special shape, a heat insulating material, and a space holding member for forming a space, and an existing vertical thatched roof plate is used. Not only can it not be done, but the construction cost will also increase.

Further, in the one described in the second prior art, an interposing material such as a wooden rafter is provided between the roof plate and the main board material so that a space is formed between them. However, in such a structure, it is necessary to provide a large number of reinforcing members on the back surface of the roof plate in the direction of the eaves so as to support the entire back surface of the roof plate above the space, especially as a roof plate. If a wide one is applied, a larger number of reinforcing materials are required, which causes a problem of high construction cost.

[0006]

[Object] An object of the present invention is to provide a structure of a thatched roof in which an air layer on the rear surface of the roof can be easily and inexpensively constructed.

[0007]

In order to solve the above-mentioned problems, the present invention provides an inner base material laid on the entire surface of a purlin and an upper surface side of the inner base material , and at least a vertical roofing member. An outer base material that supports the back surface of the flat portion of the roof plate, and an intermediate base material that is laid between the outer base material and the inner base material to form an air layer along the eaves direction,
Provided on the intermediate base material, and a holding member for holding the two joint Longitudinal direction of the adjacent longitudinal roofing plate from each other, wherein the intermediate base material is a wider than the required width of the holding member or one, in which a formed by laying over substantially the same length as the length before Kitate roofing plate configuration.

[0008]

That is, according to the present invention, by adopting the above-mentioned structure, the required width of the holding member for holding the vertically roofing roof plate between the inner base material and the outer base material laid on the entire surface of the purlin. An air layer can be easily and inexpensively constructed by laying a wider intermediate base material over a length substantially equal to the length of a thatched roof plate to form an air layer. At the same time, by laying the intermediate base material, the absent portion of the outer base material and the thermal weakness due to the seam are reinforced,
This enhances the heat insulating property.

Further, a reinforcing member for supporting the holding member is provided in the laid portion of the intermediate base material, and the reinforcing member has a height substantially equal to the height of the intermediate base material and supports the back surface of the outer base material. In addition, since the intermediate base material made of a short material is laid between each of these reinforcing members,
The required length of the fixture such as the self-drilling screw for fixing the holding member becomes short, the workability is improved, and the safety in strength related to the work is enhanced.

Furthermore, by using the same material as the outer base material as the intermediate base material, it is possible to effectively use the end material of the outer base material as the intermediate base material, thus reducing the construction cost. Can be achieved.
