〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 6.

A is the lower folded roof, and B is the upper folded roof. These folded roofs are formed with continuous peaks and valleys, and this unit roofing material 1 has an upper part 1a and a lower part 1b which are sequentially tightened to connect it to the adjacent one. There are two types: a fastening type (see Figs. 1 to 5), and a type in which the chevron portions are simply overlapped (see Fig. 6). In addition to this, although not shown, there is also a type in which the end edges of the unit roofing material 1 are fitted with a cap material and joined together.

In this way, the unit roofing material 1 is not limited to its cross-sectional shape, ridge shape, etc., as long as the peaks and valleys are formed continuously when it is roofed.

Furthermore, the lower folded roof A of the same roof location
For the upper folded roof B and the unit roof material 1, the same type of roof material is often used.

This unit roofing material 1 is made to be orthogonal (including substantially orthogonal) to a structural member 2 such as a beam or a main building, and placed on the bracket 3 of this structural member 2, so that the adjacent unit roofing material 1 in the width direction is The lower folded roof A is constructed by repeating the steps one after another in such a way that they are fastened together or overlapped with each other. At this time, in the case of fastening type unit roofing material 1,
It is attached via a hanger 3a. Next, a plurality of supports 4 such as receiving metal fittings are provided on the lower folding plate roof A so as to be higher than the height of the lower folding plate roof A at an appropriate interval (about several centimeters to several tens of centimeters). In the embodiment, the support 4 uses a heat insulating bolt or the like made of a synthetic resin material or the like. A heat insulating material 5 made of foamed synthetic resin, glass wool, asbestos, etc. is laid on the lower folded roof A. This heat insulating material 5 is often wound into a roll and coated with a synthetic resin film. An upper folding plate roof B is laid on the supports 4, 4, . . . in the same manner as the lower folding plate roof A. In particular, in the present invention, the length of the upper folded roof B is longer than the length of the lower folded roof A. That is, the unit roofing material 1 of the upper folded roof B is configured to have a longer length in the longitudinal direction than the length of the unit roofing material 1 of the lower folded roof A in the longitudinal direction.

There are multiple specific examples of this, firstly,
As shown in FIGS. 2 and 6, the lower end of the lower folded roof A under water (the eave tip) is provided to protrude to the outside of the wall 6, and at this time, the lower folded roof B is The lower end (tip of the eaves) is provided so as to be further outward and longer than the end of the lower folded roof A.

In addition, as shown in Figure 3, the lower folded roof A

It is provided outside the position 6. There are various types of heat insulating material 5, including low-density materials and high-density materials.

Reference numeral 7 indicates an upper eave front door, and 8 indicates a lower eave front door, both of which are made of metal plates and have a substantially trapezoidal shape. It is fixed to the back side of the longitudinal end. As a result, when the eaves of the upper folded roof B and the lower folded roof A are viewed from the front, the upper eave front doors 7, 7... or the lower eave front doors 8, 8
... is formed so that its lower side is approximately horizontal.

9 is a long eave wrapping material made of metal plate, with an inverted L shape.
A gutter-shaped portion 9b having a substantially U-shaped cross section is integrally formed from the lower end of the inverted L-shaped portion 9a, if necessary.

The top of the inverted L-shaped portion 9a of the eaves wrapping material 9 is fixed to the lower surface of the valley of the upper folded roof B with bolts, nuts, etc. As shown in FIG. 2, it is configured to wrap the end of the lower folded roof A on the other end side of the eaves wrapping material 9, or as shown in FIG.

In the embodiments described above, there is a case where the eaves of a roof are located below the water as a general eave part, but the same applies to the eaves part on the water side of a single-slope roof, and furthermore, the eaves at the below water side position are also applicable. The valley eaves area, which has symmetrical sections, is configured in the same way.
In the present invention, these are collectively referred to as the eaves.

Further, a heat insulating sheet made of foamed synthetic resin or the like is often adhered to the lower surface of one or both of the lower folded roof A and the upper folded roof B.

〔Effect of the invention〕

In the present invention, an upper folded roof B is laid above the lower folded roof A at an appropriate interval, and the length of the upper folded roof B is made longer than the length of the lower folded roof A. Then, an upper eave front door 7 is fixed to the lower side of the edge of the upper folded roof B, a heat insulating material 5 is filled in the space between the lower folded roof A and the upper folded roof B, and the upper folded roof B Upper eave front door 7 and lower folded roof A
By providing an eaves wrapping material 9 between the upper eaves front door 7, the eaves wrapping material, and the lower folded roof A end, the eaves insulating material 12 is filled continuously with the insulation material 5. First, it has excellent heat insulation performance, second, it prevents condensation, and third, it provides extremely good sound insulation and soundproofing.

First, the insulation material 5 is filled between the lower folded roof A and the upper folded roof B, and the eaves of the lower folded roof A are also covered with the eaves insulation material 12. The lower folded roof A can be configured to be almost cut off from the outside air, and the eaves of the double roof itself has a laminated structure filled with heat insulating material 5 inside, making it possible to significantly reduce the amount of cross-flow heat loss with the outside. In turn, it is possible to increase the heat conduction resistance value and provide an eaves insulation structure with extremely excellent insulation performance.

Second, by covering the eaves of the lower folded roof A with the eaves insulating material 12, the lower folded roof A can be configured to be substantially cut off from the outside air, and the cold at the eaves can be reduced. By eliminating the bridging effect, it is possible to prevent dew condensation from occurring on the back surface of the lower folded roof A, and to prevent adverse effects on the interior due to falling condensation.

Thirdly, by improving the insulation performance and using the eave insulation structure, we can simultaneously reduce external sounds and noise, and reduce the external noise to the upper folded roof B.
The sound is reflected by the lower folded roof A, and the eave insulating structure acts as a sound absorber, and as a result,
It also has the advantage of providing extremely good sound insulation and insulation.
