Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a thatched roof in which a circulating air layer is formed on the back side of the roof of a building.

[0002]

2. Description of the Related Art Recently, as a roof structure of a building, functions such as ventilation of the attic and heat storage effect by utilizing solar heat energy are required. A structure in which an air layer is formed on the back surface of a roof substrate has been proposed and put into practical use.

Conventionally, in such a type of thatched roof, for example, Japanese Utility Model Laid-Open No. 2-89127 (hereinafter referred to as Prior Art 1) or Japanese Utility Model Publication No. 49-81522 (hereinafter referred to as Prior Art 2). , Etc.) and the like.

[0004]

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 in the longitudinal direction of the eaves on the back surface of the roof plate so as to support the entire back surface of the roof plate above the space. If a wide roofing sheet is to be applied, a larger number of reinforcing materials will be required.

Further, in any of these prior art examples, when an attempt is made to obtain a secondary waterproofing effect by using a sheet-shaped waterproof material, the waterproof material is lost due to the force majeure of the fixing tool, and as a result, a normal waterproof construction is carried out. There was a problem that the rainy weather was bad because the structure more than the secondary waterproofing by the sheet-like waterproofing material could not be adopted.

[0007]

[Object] An object of the present invention is to provide a structure of a thatched roof, which can easily and inexpensively construct an air layer on the rear surface of the roof and can improve the rain warding performance. .

[0008]

In order to solve the above-mentioned problems, the present invention receives at least the back surface of a flat portion of a vertically-roofed roof plate on the upper surface of an inner base material laid on the entire surface of a purlin. An outer base material is provided, and a space forming / supporting member is provided between the outer base material and the inner base material along the eaves ridge direction, and the inner base material and the outer base material are interposed via the space forming / supporting member. In the structure of a vertical thatched roof in which an air layer is formed between the material and the space, the space forming and supporting member includes a central fixing portion fixed to the roof of the purlin via the inner base material, and the fixing portion. Between the eaves ridge direction and the girder row direction, which is orthogonal to the eaves ridge direction, and the space forming parts which are respectively formed upright on the girder direction, and which extend in the outer girder direction from the upper ends of these space forming parts and which are adjacent to each other in the girder direction. Flange that supports both end joints It is obtained by the formation and becomes a configuration in the.

[0009]

That is, according to the present invention, by adopting the above-mentioned structure, the space forming / supporting member formed by forming the air layer between the inner base material and the outer base material is provided with the inner base material via the inner base material. The central fixed part fixed on the upper side, the interval forming parts formed at both end portions in the girder direction of the fixing part, respectively, and the vertical roofing members extending in the outer girder direction from the upper ends of these interval forming parts and adjacent to each other. Since it is formed by the flange portions that support the joints at both ends of the roof plate in the girder direction, the air layer can be easily and inexpensively constructed.

Further, since the use of such a space forming and supporting member makes it possible to use a conventionally known roofing sheet as a vertically-roofing roofing sheet, it is not necessary to develop a conventional dedicated roofing sheet. Therefore, the cost is not increased.

Further, by arranging a space forming / supporting member of a fixed length along the eaves ridge direction at appropriate intervals, the air layer can be formed to communicate with both the eaves ridge direction and the girder direction. Therefore, the piping and wiring relating to the use of solar heat energy can be freely performed.

Furthermore, each space forming / supporting member on the inner base material is formed of a long material, and rising portions are formed between the space forming / supporting members at both ends in the column direction to prevent water leakage. By arranging the boards and positioning the upper end of the water leakage prevention board that is compatible with the lower surface of the flange part of the space forming and supporting member from both side end joints in the girder direction of the adjacent thatched roof boards. Even if rainwater or the like enters, the space forming / supporting member functions as a gutter, and this infiltrated water can be drained from the eaves, so that no water leakage occurs.

In addition, a holding member (hanger) for the roofing panel
Or water is transmitted to the space forming and supporting member, or
Even if an unexpected disaster such as damage to the vertical roofing plate occurs, effective secondary waterproofing can be obtained by the interposition of the water leakage prevention plate between the space forming and supporting members, improving the rain performance. Can be achieved.
