Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a technology for improving the waterproof performance of arched horizontal roofs.

[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]

Roofs made of tile stick roofs and seam welded stainless steel plates 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, since the slope of an arched roof is gentle, especially in the vicinity of the ridge, the slope becomes extremely small, which poses problems in terms of waterproofing, and it has not been possible to adopt a horizontal roof.

That is, the horizontal roof uses a horizontal roof board with a downward engaging part bent at the front end and an upward engaging part corresponding to the engaging part at the rear end. The engaging portions of horizontally adjacent roof sheets are engaged with the locking portions, and the roofing is sequentially done from the eave side to the ridge side.

Therefore, unless the slope of the roof base is 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, resulting in an arched roof. If the slope of the foundation is gentle, as in the case of a ridge, the horizontal roof plates located at the top level (on both sides of the ridge) may become nearly horizontal, or the slope may be reversed, causing rainwater to flow toward the ridge. There is. For this reason,
Simply installing a ridge wrapper is likely to cause water leakage accidents.

In addition, horizontally adjacent horizontal roofing boards are joined by applying waste boards to the back surfaces of their adjacent ends and covering the surfaces with covers. These joints are arranged in a staggered manner, so that rainwater that has entered the roof shingles flows out onto the surface of the lower horizontal roof shingles.

Therefore, if the drainage slope is sufficiently large, no problem will occur. However, with arched roofs, the drainage slope is gentler due to the rounded roof surface, and the drainage slope is particularly gentle at the ridge. As this drainage slope becomes extremely gentle as it approaches the area, there is a high possibility that rainwater will infiltrate if only the connection structure using the above-mentioned waste boards and cover is used.

The purpose of the present invention is to solve the above problems and provide an arched horizontal roof with high waterproof performance.

[Means for solving problems]

The technical measures taken by the present invention to achieve the above objectives are as follows. That is, in the arched horizontal roof according to the present invention, the first drainage ditch is provided in the roof base of the ridge along the ridge, and the horizontal roof is installed at multiple positions in the longitudinal direction of the ridge and adjacent in the horizontal direction. A second drain is installed on the roof base below the joint between the boards, extending from the ridge to the eaves. They are distinctive in that they are overlapped and intersect, and a drainage port is formed in the portion of the first drain that overlaps the second drain.

[Effect]

According to the above configuration, since the drainage slope of the horizontal roof plates located on both sides of the ridge of the arched roof is gentle, even if rainwater may enter from the ridge,
Since the ridge is equipped with the first drain, rainwater that enters the building will flow over this first drain.

A second drain is installed below the joints between horizontally adjacent horizontal roof panels from the ridge to the eaves, so rainwater that has entered through the joints between horizontal roof panels is collected at each joint. Even if it spills from the installed wasteboard, it will flow down to the eaves through the second wastewater drain.

In addition, the first drain cutter and the second drain cutter intersect so that the first drain cutter overlaps the upper end of the second drain cutter, and the water drains to the part where the first drain cutter overlaps the second drain cutter. Since the openings are formed, rainwater that has entered the top of the first drain will flow to the second drain through these drains.

〔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 of the horizontal roof plate 1, and an upward locking portion 1b corresponding to the engaging portion 1a is bent at the rear end. 1st
Reference numeral 3 in the figure indicates 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 (for example, sheathing board, rafters, heat insulating material, etc.) below this asphalt roofing 4a may be of a well-known structure, so the explanation will be omitted, and hereafter, asphalt roofing 4a
This will be simply referred to as the roof base 4, including the roof base 4.

As shown in FIGS. 3 and 4, the roof base 4 of the ridge is provided with a first drain 5 whose lower end 5a is bent upward along the ridge. At a plurality of positions in the longitudinal direction of the ridge, and on the roof base 4 below the joint part 3, second drains 6 with both side edges 6a bent upward are provided from the ridge to 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 (see Fig. (not shown), and the rear end of the horizontal roofing board 1 located at the top level (on both sides of the ridge) is fixed onto the raised material 9 with fasteners (not shown) such as nails or screws. There is. A wood base 10 is fixed to the rear end of the uppermost horizontal roof board 1 with fasteners (not shown) such as nails or screws. 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.

In the above embodiment, the drain port 7 was formed by cutting out the lower edge 5a of the first drain cutter 5, but instead of cutting out the edge 5a, the first drain cutter 5 The drainage port 7 may be formed by forming a through hole in a portion that overlaps with the second drain. Further, in the above embodiment, as shown in FIGS. 2 to 4, the locking portion 1b of the uppermost horizontal roof board 1 is locked to the rear end surface (end surface on the water side) of the wood base 10. Although the horizontal roofing board 1 is prevented from pulling out to the underwater side, at the time of constructing the uppermost horizontal roofing board 1, a space larger than the longitudinal width of the horizontal roofing board 1 remains in the ridge. If not, as shown in Figure 5, cut off the required amount of the rear end of the uppermost horizontal roof board 1, bend the cut end upwards, and attach this part to the wooden base 1.
The rear end surface of the 0 is locked.

[Effect of idea]

Since the present invention has the above-described configuration, it can achieve the following effects.

In other words, even if rainwater may infiltrate from the ridge due to the gentle drainage slope of the horizontal roof plates located on both sides of the ridge, the first drain is installed along the ridge. Since the intruding rainwater is caught by the first drain, it is discharged to the second drain through the drain port formed in the first drain. The second drain is provided below the joint between horizontally adjacent horizontal roof panels from the ridge to the eaves, so rainwater that has entered from the joint can be drained from the drain installed at each joint. Even if it spills from the board, it will flow down to the eaves through the second drain.

Therefore, it is possible to realize an arched horizontal roof with high waterproof performance.
