Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a roof structure constructed using folded roofing materials.

[Background Art] An example of roofing materials used for houses and the like is folded roofing materials. This folded roofing material is formed into a wave shape, and the roof structure using it is
It is called a corrugated roof and is often used on single-family homes and apartment complexes.

Figure 8 shows an example of such a folded roof.
As shown in the figure, this folded roof is composed of a flat folded roofing material 51. A ventilation hole (not shown) is formed in the center, and the ventilator 10 is mounted on the ventilation hole (not shown). 5
4 is the outer wall. In the roof structure constructed using this roofing material 51, since the roofing material 51 has a flat shape, the space (attic air volume) between it and the ceiling 53 is small, the heat retention is poor, and the design is poor. It was inferior. In addition, it could not be said that the ventilation was good.

[Purpose of the invention]

In view of the above, an object of the present invention is to provide a folded roof structure with a great design, great heat retention, and great ventilation.

[Disclosure of the invention]

In order to achieve the above object, the present invention provides a roof structure configured using a folded roofing material formed into a wave shape, in which at least a part of the folded roofing material has a raised central portion. The mountain-shaped folded roofing material is attached to a horizontal roof beam via a tight frame with different heights depending on the location. The gist of the folded roof structure is that a mountain-shaped raised part is formed to create a space in the attic, and ventilation holes are provided in the folded roof material at least in the raised part.

This invention will be explained in detail below.

The above-mentioned waveforms have various cross-sectional shapes, such as those with a sine function or cosine function curve, rectangular waves, rounded ones, trapezoidal waves, and rounded ones, and are not particularly limited. Further, the waveform is not limited to a periodic shape.

The material for the folded roofing material is not particularly limited, and examples include, but are not limited to, steel plates such as galvanized steel plates, colored galvanized iron plates, and the like.

As for the folded roofing material constituting the roof, only a mountain-shaped folded roofing material with a raised center part may be used, or a combination of a mountain-shaped folded roofing material and a conventional flat roofing material may be used. A folded roofing material may also be used, and there is no particular limitation. By constructing the roof using mountain-shaped folded roofing materials, a varied appearance can be obtained and the design can be enhanced.

The above-mentioned mountain-shaped folded roofing material can be obtained, for example, by subjecting a portion of the roofing material to a curved surface. For example, as shown in Fig. 6, the folded roofing material 2 has a mountain-shaped roofing material 2 whose central part is raised like a flat plateau while leaving both ends, or as shown in Fig. 7, the folded roofing material 2 It can be made into a chevron-shaped structure in which the center part is raised in a triangular shape, leaving both ends of . However, the method of making the folded roofing material into a mountain shape by raising the central portion is not limited to the above method.

Ventilation holes are provided in the folded roofing material at the raised portion of the roof structure. This is to ventilate the attic (behind the ceiling). In this invention, since ventilation holes are formed at least in the raised portions, gas rises through the spaces in the raised portions A and B and passes through the ventilation holes, as shown in FIGS. 6 and 7. and exit outside (indicated by arrow). For this reason, ventilation is great. With conventional roof structures constructed using only flat folded roofing materials, as shown in Figure 8, it is difficult for gas in the attic to escape to the outside, and it becomes trapped, resulting in poor ventilation. . Note that if the ventilation holes are left as they are, rainwater may enter, so it is a good idea to install a ventilator above the ventilation holes. This allows for great ventilation and eliminates the worry of rain leaks. The ventilation holes may be formed in the folded roofing material in areas other than the raised portion.

The above-mentioned folded roofing material is supported and attached to roof beams that are installed in a horizontal plane via tight frames that vary in height depending on the location, thereby forming a roof. That is, since the vertical distance between the horizontal plane constituted by the roof beam and the mountain-shaped folded roofing material differs depending on the location, the height of the tight frame is set according to the distance at each location.
The tight frame is fixed to the roof beam, for example with bolts and nuts. The portion of the tight frame that receives the folded roofing material is preferably shaped to match the uneven shape of the lower surface of the folded roofing material.
The folded roofing material is firmly fixed to the tight frame. The folded roofing material is fixed to the tight frame by using, for example, bolts and nuts, or bolts such as sword-point bolts, but the method is not limited to this method. The material of the tight frame is not particularly limited, and examples include, but are not limited to, steel plates such as galvanized steel plates, colored galvanized iron plates, and the like.

The folded roof structure according to the present invention uses mountain-shaped folded roofing materials in whole or in part to form a mountain-like raised part in a part of the roof, so it is better than a flat roof structure. , the design quality becomes greater. In addition, the space between it and the ceiling is larger, and heat retention is better. Since ventilation holes are formed in the folded roofing material at least in the raised parts, ventilation performance is great. Moreover, the mountain-shaped folded roofing material can be supported by the above-mentioned tight frames that vary in height depending on the location, and there is no need to go to the trouble of constructing a roof structure to form a mountain-shaped roof.

A more detailed explanation will be given below with reference to the drawings showing one embodiment.

〔Effect of the invention〕

As seen above, the folded roof structure according to the present invention is constructed by using a mountain-shaped folded roofing material for all or part of the folded roofing material, and the folded roof structure at least in the mountain-shaped raised part. Since ventilation holes are formed in the material, it has a great design, great heat retention, and great ventilation. Also, no roof assembly is required. In particular, the roof beams constituting the frame of the building are constructed using normal horizontal roof beams, and the above-mentioned mountain-shaped roof beams are placed on top of the roof beams via tight frames with different heights depending on the location. That is, since the folded roofing material having a curved or bent surface shape is attached, the chevron-shaped folded roofing material can be constructed without impairing the function or workability of the building.

That is, since the roof beams are required to provide the structural strength of the building and also have the function of supporting the ceiling material, it is preferable to construct them in a horizontal plane.
Furthermore, frame structures such as roof beams and columns are more difficult to process and assemble than roofing materials, so it is easier to construct them if the structure is as simple as possible.

Therefore, the roof beams themselves are constructed in a horizontal plane like in normal buildings, and tight frames with different heights depending on the location are installed on top of the horizontal roof beams. If you install mountain-shaped folded roofing materials, you can reliably and firmly install curved or curved mountain-shaped folded roofing materials using the same installation procedure as conventional horizontal folding roofing materials. can do.

Moreover, since there is a wide space between the horizontal roof beams and the mountain-shaped folded roofing material, the heat retention of the building is improved, and the space is also used to provide good ventilation.
