Abstract

(57) [Summary] (Corrected) [Purpose] The purpose is to obtain a double thatched roof in which an outer roofing material is fixed to a corrugated underlaying material placed on a supporting member such as a main house. [Structure] A corrugated roofing material 18 is arranged on a main member 12 and a supporting member 16 such as a base material in a direction orthogonal to the eaves ridge direction, and an outer roofing material 24 is fixed on a mountain portion of the corrugated roofing material. A rafter member 3 having a substantially hat-shaped cross section between the supporting member and the inside of a predetermined mountain portion of the corrugated underlaying material.
No. 0 is provided to fix the rafter member to the support member, and further, the outer roofing member and the hat portion of the rafter member are fixed to each other by the fitting through the corrugated lowering member. In this double-roofed roof, the outer roofing material is fixed to the rafter member via the corrugated lowering material, so that not only the mounting strength but also the roof structure itself can be enhanced.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a double thatched roof in which an outer roofing material is fixed to a corrugated bottoming material arranged on a supporting member such as a purlin.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, a corrugated underlaying material having peaks and troughs is arranged on a support member such as a purlin or a base material in a direction orthogonal to the eaves direction, and the corrugated underlaying material is placed outside on the peaks. The double-roofed roof constructed by fixing the roofing material improves the heat insulation by the air layer (space) formed between the corrugated underlaying material and the outer roofing material or between the corrugated underlaying material and the supporting member. It is widely used because it can be designed.

By the way, in the double-roofed roof constructed in this manner, the outside roofing roofing material and the corrugated underlaying material are only directly fixed by means of a fixing tool such as a screw, so that the fixing tool is loose and stable. In addition to lacking in performance, its fixing strength is also low, so there was a concern that the outer roofing material would peel off when exposed to strong winds such as typhoons.

Further, since the weight of the outer roofing material is directly added to the corrugated lowering material, there are various problems to be solved, such as the need to narrow the interval between supporting members such as purlins due to strength problems. Was pointed out.

[0005]

[Means for solving the problem]

 Therefore, in this invention, a corrugated underlaying material having peaks and troughs is arranged on a support member such as a purlin or a base material in a direction orthogonal to the eaves ridge direction and the corrugated underlaying material is piled up. A metal rafter member having a substantially hat-shaped cross section is arranged between the supporting member and the inside of a predetermined mountain portion of the corrugated roofing member in a double-roofed roof in which an outer roofing member is fixed on the above-mentioned part. By fixing this rafter member to the support member and further fixing the outer roofing material and the hat portion of the rafter member with the fixture via the corrugated underlaying material, the wobble of the fixture is prevented and the roof structure itself. It is intended to increase the

[0006]

[Action]

 In the double-roof roof according to the present invention, since the outer roofing roofing material and the metal rafter member disposed inside the predetermined mountain portion of the corrugated underlaying material are fixed by the mounting tool via the corrugated underlaying material, the fixture is attached. The outer roofing material is supported by the rafter members via the corrugated underlaying material, and the strength of the roof structure can be improved.

[0007]

【Example】

 Next, an embodiment of the double-roofed roof according to the present invention will be described in detail with reference to the accompanying drawings.

In the accompanying drawings, a double-roofed roof 10 according to the present invention has a lower roofing material 18 arranged on a support member 16 such as a main building material 12 and a field material 14 in a direction orthogonal to the eaves ridge direction. It is basically configured by fixing an outer roofing material 24 composed of a roofing base material 20 such as a heat insulating material and a roofing material 22 arranged on the underlaying material 18 to the support member 16.

The lower roofing material is configured as a square wave-shaped lower roofing material 18 obtained by bending a coated metal steel plate, and a mountain portion 26 and a valley portion 28 connected to the square wave lowering material 18 are formed. Is arranged on the support member 18 so as to extend along the eaves ridge direction. In addition, the cross-sectional shape is substantially hat-shaped between the inside of a predetermined mountain portion 26a and the field material 14 (support member 16) among the many mountain portions 26 formed on the square wave underlaying material 18. The formed metal rafter 30 is disposed, and both side pieces 30a, 30a of the hat-shaped rafter 30 are attached to the base material 14 and the main building material 12 via the mounting screws 32.

On the other hand, as is apparent from FIG. 2, the roof members 22 are connected to each other by a fastener, and the suspension 34 arranged in the fastener portion is attached with a mounting screw 36 to the roof substrate 20. Then, it is fixed to the hat portion 30b of the metal rafter 30 through the square wave underlaying material 18.

In FIG. 1, reference numerals 38 and 40 are air layers formed between the field material 14 and the square wave underlaying material 18 and between the square wave underlaying material 18 and the roof base material 20. Thus, these air layers 38, 40 function as heat insulating layers between the roof and the interior.

In the double-roofed roof 10 according to the present invention configured as described above, the outer roofing roofing material 24 such as the roofing material 22 and the roofing base material 20 is not directly attached to the square wave lowering material 18, but Since it is firmly fixed to the metal rafter 30 by the mounting screw 36 via the square wave underlaying material 18, the mounting strength can be sufficiently maintained, and therefore, the roof material 22 is peeled off due to wobbling or strong wind. Can be prevented as much as possible.

The weight of the outer roofing material 24 including the roofing material 22 and the roofing base material 24 is supported by the metal rafters 30 via the square wave roofing material 18, so that the distribution of the main material 12 is considered in terms of strength. There is no need to make adjustments such as designing the installation interval narrow.

[0014]

[Effect of device]

 As described above, according to the double-roof roof of the present invention, the rafter member is arranged inside the predetermined mountain portion of the corrugated underlaying material, and the outer roofing material is attached by the fitting through the corrugated underlaying material. Since it is fixed to this rafter member, the fixture does not wobble and becomes unstable, and the weight of the outer roofing material is supported by the corrugated underlaying material and the rafter member arranged inside this corrugated underlaying material. As a result, the roof strength is improved, and further, the heat insulation function can be maintained by the air layers formed between the field material and the corrugated underlaying material and between the corrugated underlaying material and the roof underlaying material. And its practical effect is extremely large.

Although the preferred embodiment of the double-roof roof according to the present invention has been described above, the present invention is not limited to this embodiment, and various modifications can be made without departing from the spirit of the present invention. Of course, it can be modified.
