Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a folded roof that can prevent the occurrence of thermal distortion due to thermal expansion and contraction at the ridge portion of a folded roof, and furthermore enable ventilation at the ridge portion. This invention relates to a ridge device on a roof.

[Conventional technology and its problems]

Conventionally, folded roofs with continuous peaks and troughs were generally installed with a ridge wrapping material of an appropriate length in the longitudinal direction, and some of the ridge wrapping materials were attached so that they could expand and contract. However, due to the thermal expansion and contraction of the folded roof, the ridge covering material suffered from metal fatigue, causing cracks to form in the middle and breakage, which caused rainwater to infiltrate.

[Means to solve the problem]

Therefore, as a result of intensive research in order to solve the above-mentioned drawbacks, the inventor has proposed the present invention, in which the peak part at the upper end of the water side of a folded roof in which the peak part and the valley part are continuous is provided at the ridge part. attached to the roof brackets on the left and right sides respectively, forming the ridge part as an opening, and providing a stop door or a rising part at the water side end of the valley of the opposing architectural board in the ridge part, and Fix the ridge cutting material to the peaks on the water side of the opposing building boards at the ridge part, form an appropriate gap between the left and right ridge cutting materials, and attach a surface to the lower end of the ridge cutting material on the underwater side. A door plate is provided, a mounting hardware is provided on the beam of the ridge part so as to protrude above the opening of the ridge part, and a ridge board is installed on the mounting hardware, so that both lower end pieces of the ridge board are attached to the left and right sides. The ridge plate may be in contact with the top surface of both ridge panels, or, in the configuration of the invention, an appropriate hollow portion may be provided between both lower end pieces of the ridge board and the upper surface portions of both left and right ridge panels. By making it possible to ventilate the air from the opening through the empty space, it is possible to prevent the occurrence of thermal distortion due to thermal expansion and contraction at the ridge part of the folded roof, making it possible to improve rain control and to eliminate the above-mentioned drawbacks. This has been solved and the purpose has been achieved, and the purpose is also to enable ventilation in the ridge.

The bottom portions of the roof brackets 2 are placed on the left and right sides of the beam 1 and fixed by welding or the like. In the embodiment, a beam member 1 with a wide upper surface was used, but the upper surface may be narrowed and mounting pieces for the bottom of the roof bracket 2 may be provided on both sides, or the roof brackets 2 may be attached to a beam. It may also stick to the purlins 13, 13 on both sides of the material 1. A peak portion 4b at the upper end of the folded roof A on the water side is attached to the top of the roof bracket 2. In this way, the folded roof A, A is the roof bracket 2 of the ridge,
The entire roof is constructed such that both sides face downward with 2 as a boundary, and appropriate openings 3 are formed at the ridge portions of the roof. That is, an appropriate opening 3 is formed between the opposing upper ends of the folded roofs A, A on the water side.

Further, the top of the mountain portion 4b is approximately flat as shown in FIGS. 1 and 7, but it may also have a hat-shaped cross section (see FIG. 8) or a chevron-shaped arc cross section. Yes (see Figure 9).

As shown in FIGS. 1 and 2, there are stop doors 6, 6 at the water-side upper ends of the valleys 4a, 4a of the architectural boards 4, 4 constituting the opposing folded roofs A, 4. If the construction board 4 is fixed watertightly, or if the height of the trough 4a of the building board 4 is low, the rising parts 7, 7 are bent at the upper end of the trough 4a on the water side, as shown in FIG. has been done.

〔Effect of the invention〕

First, the invention of claim 1 (first invention)
In this case, the peak part 4b at the upper end on the water side of the folded roof A, in which the peak part 4b and the valley part 4a are continuous, is attached to the left and right roof brackets 2, 2 provided at the ridge part, respectively. The part is formed as an opening 3, and the valley part 4a, 4a of the building boards 4, 4 facing the ridge part
A stop door 6, 6 or a rising part 7, 7 is provided at the water side end of the ridge part, and ridge cutters 8, 8 are installed on the water side mountain parts 4b, 4b of the building boards 4, 4 facing each other at the ridge part. is fixed, an appropriate interval is formed between the left and right ridge draining materials 8, 8, and a door plate 9 is provided at the lower end of the ridge draining material 8 on the water side side, protruding above the opening 3 of the ridge portion location. Mounting hardware 10 is installed on the beam 1 at the ridge portion so that the ridge board 11 is installed on the mounting hardware 10, and the ridge board 1
By making both the lower end pieces 11c, 11c of 1 touch the upper surface parts 8a, 8a of both the left and right ridge cutters 8, 8, firstly, the thermal expansion and contraction of the ridge parts of the folded roofs A, A is prevented. secondly, the ridge portion can be better protected from rain; and thirdly, it has excellent workability and affordability.

To explain this effect in detail, first, the building boards 5 constituting the folded roof A are thermally expanded and contracted in the longitudinal direction according to the outside temperature, and the ridge portions of the folded roofs A,A are Even if expansion and contraction appears in the roof bracket 2, there are roof brackets 2, 2 on the left and right sides of the beam 1 at the ridge, and the thermal expansion and contraction in the longitudinal direction of the folded roof A will be absorbed by the roof brackets 2. It can be absorbed by slight tilting and swinging, and the opening 3 is present, and the ridge board 11 covering the opening 3 is configured not to stick to the left and right ridge cutters 8, 8. By doing so, no thermal stress is generated in the ridge board 11 and the building boards 4 constituting the folded roof A, and the occurrence of thermal strain can be reliably prevented. In addition, since the height of the folded roof A is high and the section modulus is large, a large amount of thermal stress is added due to thermal expansion and contraction, which tends to cause the plate cracking phenomenon to occur frequently. It can be eliminated. Furthermore, although it is possible to prevent the occurrence of thermal distortion in the building boards 4 constituting the ridge board 11 and the folded roof A,
Or the presence of the rising portion 7 or the presence of both lower end pieces 1 of the ridge board 11
By making 1c and 11c contact the upper surfaces 8a and 8a of both left and right ridge draining members 8 and 8, it is possible to reliably block rainwater from entering the interior, and improve rain-proofing (watertightness). We can provide an excellent ridge device for folded roofs. Moreover, the structure of the ridge device is relatively simple, and the construction can be carried out easily and quickly without any danger by working from the roof, which in turn can reduce the construction cost.

Next, the invention of claim 2 (second invention)
In the configuration of the first invention, an appropriate hollow part 12 is formed between the lower end pieces 11c, 11c of the ridge board 11 and the upper surface parts 8a, 8a of both the left and right ridge draining members 8, 8. By making it possible to ventilate the air from the opening 3 through the empty part 12,
A major feature of the building is that it allows ventilation at the ridge.

To explain this in detail, the ridge board 11 and the ridge cutters 8, 8
and serves as a ventilation member, and good ventilation can be achieved by the outflow and inflow of air from the hollow part 12. this is,
The only thing to do is to simply replace the mounting hardware 10 with an appropriate one with a higher height and set it to form the empty space 12, and the ridge system, which also includes a ventilation system, can be created without the need for any new separate parts. It has a huge impact on what it can provide. Of course, even with this ventilation system, the rain can be kept out.

The other configurations are the same as those of the first invention, and the same effects can be achieved.
