Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a ridge in an arched horizontal roof.

[Conventional technology]

Traditionally, arched roofs have been constructed either exclusively in the form of tile rods or by seam welding of stainless steel plates.

[Problem that the invention attempts to solve]

Tile stick roofs and stainless steel seam welded roofs had a poor appearance and tended to have a straight shape, which did not match the highly decorative arched roofs.

In addition, the roof is made of seam welded stainless steel plates.
Although it has high waterproof performance, the biggest problem is that the material and construction costs are high.

For this reason, even for arched roofs, there is a demand for horizontal roofs that match well with the design of arched roofs and can be constructed at a much lower cost than roofs made of seam welded stainless steel plates. It has reached this point.

However, in arch-shaped roofs, because the slope of the ridge is gentle, the top surface of the horizontal roof plates located at the top level (on both sides of the ridge) may be close to horizontal or have an opposite slope, causing problems in terms of waterproofing. It was hot.

In other words, the horizontal roof has a downward engaging part bent at the front end, which is the eave side, and an upward engaging part, which corresponds to the engaging part, is bent and formed at the rear end, which is the ridge side. Roofing is carried out sequentially from the eave side to the ridge side by using the roofing boards and engaging the engaging parts of the horizontal roofing boards adjacent in the front-rear direction with the locking parts. Therefore,
If the slope of the roof base is not steep to a certain extent, it will not be possible to secure the drainage slope of the board located between the engaging part and the locking part of each horizontal roof board, and the ridge of the arched roof will If the slope of the foundation is gentle, as in the example above, the horizontal roof plates located at the top level (on both sides of the ridge) may become nearly horizontal, or may have an opposite slope, allowing rainwater to flow toward the ridge. For this reason, simply providing a ridge wrapper does not prevent rainwater from entering, and water leakage accidents are likely to occur.

The present invention was developed in view of the above circumstances, and its object is to improve the drainage performance of the ridge of an arched horizontal roof.

(Means for Solving the Problems) In order to solve the above problems, the technical means taken by the present invention are as follows. That is, the structure of the ridge in the arched horizontal roof according to the present invention is an arch in which the ridge side portion of the uppermost horizontal roof plate, which is placed on the roof base, is covered by the ridge wrapping. The structure of the ridge part of a type horizontal roof, in which raised materials are attached to the roof base on both sides of the ridge part, and the horizontal roof board located at the top level is placed on top of the raised materials. It is characterized by a horizontal roof plate that has a drainage slope from the ridge side to the eave side.

[Effect]

According to the above configuration, the ridge side part of the horizontal roof board located at the top level is placed on top of the raised material, so the roof base is formed in an arch shape and the slope is gentle near the ridge. Regardless, sufficient drainage slope will be ensured for the horizontal roof plates on both sides of the ridge.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

Figures 1 and 2 show an arched horizontal roof. In the figure, 1 is a horizontal roof plate made of painted steel plate, and 2 is a ridge cover made of painted steel plate. As shown in Figure 2,
A downward engaging portion 1a is bent at the front end facing the eaves of the horizontal roof board 1, and an upward engaging portion 1b corresponding to the engaging portion 1a is bent at the rear end facing the ridge. It is formed. Reference numeral 3 shown in FIG. 1 is a joint between horizontally adjacent horizontal roof panels 1. Since these joints 3 have a well-known structure, illustrations and explanations of their specific configurations will be omitted, but the joints 3 are made by connecting the surface with a scrap board (not shown) that is applied to the back side of the adjacent end of the horizontal roofing board 1. As shown in the figure, they are arranged in a staggered manner so that rainwater that has entered onto the shingles flows out onto the surface of the lower horizontal roof board 1.

Figures 3 and 4 show the structure of the ridge of an arched horizontal roof. 4a is asphalt roofing. The roof base under this asphalt roofing 4a (for example, roofing boards, rafters, insulation materials, etc.) may be of a well-known structure, so its explanation will be omitted and it will simply be referred to as the roof base 4. .

As shown in FIGS. 3 and 4, on the roof base 4 of the ridge, on top of the asphalt roofing 4a,
A first drainage cutter 5 whose edge 5a on the lower side of the water is bent upward is provided along the ridge. At a plurality of positions in the longitudinal direction of the ridge and on the roof base 4 below the joint 3, second drains 6 with both side edges 6a bent upward are installed from the ridge on the asphalt roofing 4a. It is placed over the eaves.

These first and second drainers 5 and 6 are arranged to intersect with each other such that the first drainer 5 overlaps the upper end of the second drainer 6. A drain port 7 is formed in the portion of the first drain drain 5 that overlaps the second drain drain 6, and rainwater that has entered the first drain drain 5 flows out through the drain port 7 onto the second drain drain 6. It is structured as follows. To explain more specifically, the portion of both side edges 6a of the second drain cutter 6 located below the first drain cutter 5 is crushed into a flat shape, and the first drain cutter 5 and the second drain cutter 6 are separated. The overlap prevents this part from becoming extremely thick.
And among the lower water side edge 5a of the first drainage cutter 5,
The drain port 7 is formed by cutting out a portion located directly above the second drain 6.

In this embodiment, as shown in FIGS. 2 to 4, the first drainage drainer 5 is composed of two plates divided around the ridge, and the rising plate parts of both plates are connected to each other at the ridge. Although they are constructed by being fastened together at the top, it goes without saying that the first drainage drain 5 may also be formed from a single plate.

8 in FIG. 4 is a hanger for fixing the horizontal roofing board 1 to the roof base 4.

On the roof base 4 of the ridge, wooden raising members 9 of appropriate thickness are placed continuously (or intermittently) along the entire length of the ridge on both sides of the ridge, and fasteners such as nails or screws (not shown) are placed on each side of the ridge. The rear end, that is, the ridge side portion, of the horizontal roofing board 1 located at the top level (on both sides of the ridge) is fixed to the raised material 9 with fasteners such as nails or screws (not shown). Fixed. Caulking 11 is applied to the corners of the wooden base 10 and the horizontal roofing board 1, and the top is covered with asphalt roofing 12, and the top is further covered with the ridge wrapping 2. Both sides of the wood base 10 are fixed to the underwater side end surface of the wood base 10 with fasteners (not shown) such as nails or screws.

FIG. 5 shows another embodiment of the invention. In this embodiment, after a raised material 9 is fixed to a roof base 4, an asphalt roofing 4a is constructed on top of the raised material 9, and then an asphalt roofing material 4a is constructed on top of the raised material 9. After constructing waste water cutter 5,
A feature is that the rear end, that is, the ridge side portion, of the horizontal roof plate 1 located at the top level (on both sides of the ridge) is placed on top of the bulge of the first drainage drain 5 to ensure a drainage slope.
Incidentally, if the first water drainer 5 has a sufficiently high rigidity, it is also possible to use the bulge portion as a raising member and omit the illustrated raising member 9.
Further, in the embodiment shown in FIGS. 2 to 4, the locking portion 1b of the uppermost horizontal roofing board 1 is locked to the rear end surface (the end surface on the water side) of the wood base 10, and the horizontal roofing board 1 is However, when the uppermost horizontal roofing board 1 is installed, if there is no space left in the ridge that is equal to or larger than the front and rear width of the horizontal roofing board 1. As shown in FIG. 5, the required amount of the rear end of the uppermost horizontal roof board 1 is cut off, the cut end is bent upward, and this part is secured to the rear end surface of the wood base 10. be.

[Effect of idea]

The present invention has the above-mentioned configuration, and since the ridge side portion of the horizontal roof board located at the top level (on both sides of the ridge) rests on the raised material, the roof substrate at the ridge part is reduced due to the arched roof. Even though the slope is gentle, the drainage slope will be maintained. Therefore,
Just by installing a simple ridge cover in the same way as the ridge of a normal horizontal roof, it is effective to prevent rainwater from entering.
