[Conventional technology]

Conventionally, a horizontal roofing method consisting of a metal roof shingle that is installed along the water gradient of the roof from the ridge to the eaves and perpendicular to a bark or a field board, is protruded from the upper edge of the roof shingle. After the hooks are locked to the water return section that maintains the waterproofness and strength, the lower part of the roof shingle, which is located on the upper stage, is locked and tightened in this order. The roof is shingled.

The joints in the vertical direction of this roof will be tightened or abutted on the left and right adjacent shingles, then a drain plate will be laid on the lower surface, and a joint cover will be placed on the surface of the shingles. I'm doing rain.

However, with this type of thatched roof, the flow of rainwater is easy to spread in the horizontal direction, and the rainwater is blown into the joints by the strong wind and the rainwater sucked in by the dust adhering to the overlapping part The structure was easy to penetrate.

[Problems to be solved by the invention]

As a solution to this problem, the roof base has been subjected to a rain lay by laying a waterproofing material such as asphalt roofing as a waterproof underlaying material. However, since the suspension for fixing the roof plate is a method of directly penetrating the waterproof plate with a nail or the like and attaching it to the base, if rainwater enters from the overlapping surface of the roof plate, the rainwater will reach the base through the nail hole. There were problems such as infiltration and rain leakage, as well as corrosion of the groundwork, which reduced the strength of the building.

In addition, a method of fixing the roof shingle to the top using a molded product such as a metal rafter is also adopted, but since a hole is opened in this molded product, it is necessary to prevent water from entering from the opening. There was a difficult problem.

The present invention has solved the above-mentioned problems, and an object of the present invention is to be able to roof a roof plate using a rafter without opening a hole in a roof base surface, and to have excellent breathability and waterproofness. It is an object of the present invention to provide a waterproof and waterproof structure roof.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, a description will be given of a foundation structure of a roof on which a ventilation waterproof structure roof according to the present invention is laid. In this embodiment, a foundation of a roof plate is constituted by a base plate 8.
At the same time, woody trees 7,7, ... are installed in parallel and at equal intervals from the ridge to the eaves. And the top surface 7a of each rafter 7
The cover plate 1 shown in FIGS. 1 and 2 is attached via a fastener 9 such as a nail.

The covering plate 1 is formed in a flat elongated shape having a predetermined thickness and a width larger than the width of the top surface 7a of the rafter, and the water drainage pieces whose both end side edges are bent downward at right angles.
1a, 1a are formed. Further, as a modified example, by forming a concave portion 1b along the longitudinal direction on the back surface of the central portion and providing the seal material 5 by sticking or the like, the covering material 1 provided with the seal material 5 When mounted on
A cover plate 30 that can prevent water from entering through the opening of the stopper 9a may be configured.

Waterproof boards 2 and 20 shown in FIGS. 3 and 4 are laid between adjacent rafters 7 and 7, respectively. The waterproof plate 2 has a length substantially equal to the dimension between the laying trees 7 and 7 and is formed in a long shape having a predetermined thickness. Slightly lower than the height of
Water return pieces 2a, 2a bent upward are formed, and extension pieces 2c, 2c extending outward are formed at the upper end. As a modified example of the waterproof plate 2, a waterproof plate 20 in which rectangular drain grooves 3 are formed integrally with the bent main body 2 b at both side edges in the longitudinal direction, and the back surface of the main body 2 b is filled with the heat insulating material 6. Can be configured. In the case of the waterproof plate 20, the central part of the main body 2b is divided into two parts in the longitudinal direction as shown in the figure, and when the corrugated uneven part 4 is attached in the longitudinal direction at both ends, the uneven part is formed.
By connecting a sealing material between 4 and 4, it is possible to prevent rainwater from being drawn in by capillary action. In addition, this uneven portion 4
Thereby, the working width of the waterproof plate 20 can be freely adjusted.
Laying of the waterproof plate 20 having the divided structure can be easily performed.

As the material of the covering plates 1 and 30 and the waterproofing plates 2 and 20, a synthetic resin plate or a metal plate can be used, and a wider range of materials can be used, and materials having excellent durability, workability, and economy can be used. .

Next, an example will be described in which a horizontal roof B is laid on a foundation structure A of a roof constituted by the covering plates 1 and 30 and the waterproof plates 2 and 20.

The shingle 10 used for the side-roofing roof B is a molded product made of metal, and has a configuration in which one end of the main body 10c is bent inward and turned outward as shown in FIG. Equipped with a raised start-up fixing portion 10a, bent downward at the other end,
Further, a hook 10b formed in a hook shape directed inward and downward is provided.

The hanging member 11 for fixing the roof plate 10 is shown in FIG. 8, and has an inclined rising portion 11b formed at one end of a flat metal lid 11a. A letter-shaped engaging portion 11c is formed. The lid 11a is provided with a hole 11d for a fastener.

Although not shown, a waterproof underlaying material such as asphalt roofing is laid on the entire surface of the roof base plate 8 to ensure the perfection of the waterproof surface, and wooden rafters used in the general construction method are used. 7, 7, ... are installed on the base plate 8 in parallel with the roof from the ridge to the tip of the eaves and at regular intervals with fasteners such as nails (not shown).

Then, as described above, the waterproof plate 2 is fitted between the trees 7 and 7, and the waterproof plate 2 is provided without any gap on the entire surface of the base plate from the ridge to the eaves.
Is placed. In the illustrated case, a gap is formed in the water return piece 2a of the waterproof board 2 with respect to the side surface of the rafter 7; however, this is for the sake of convenience, and in fact, both are closely contacted. When the roof is roofed, as described later, the waterproof plate 2 is not directly exposed to the outside air, so that the waterproof plate 2 is not affected by external forces such as ultraviolet rays and wind, and does not need to have a sufficient strength. In addition, the upper end of the water return piece 2a may be temporarily fixed to the side of the rafter 7 with a nail or the like at several places, or may be stuck to the ground surface with an adhesive or the like. It is configured to ensure waterproofness without opening.

Next, the covering plate 1 is equally distributed on the top surface 7a of the rafter 7 so that the left and right drainage pieces 1a, 1a are arranged to protrude from the water return piece 2a of the waterproof plate 2, and a fastener 9a such as a nail is attached. Using this, the covering plate 1 is fixed to the top surface 7a of the rafter 7. The stopper 9 is coated with a sealing material (not shown) to ensure waterproofness.

The seam in the longitudinal direction between the cover plate 1 and the waterproof plate 2 is such that the cover plate 1 and the waterproof plate 2 located on the upstream side are overlapped with a sufficient overlap allowance, and the sealing material is filled with the one located on the downstream side. And you can pay
The ends can be butt-connected to each other and tightly adhered with a sealing material or an adhesive. In addition, using a joiner 13 having a U-shaped fitting groove 14 shown in FIG. 6, a connection end portion such as the cover plate 1 is inserted into the fitting groove 14 and filled with a sealing material to form a dense body. It can also be a seam.

The roof base structure having such a structure is provided with a fixing portion 10 at right angles to the trees 7, 7,...
After positioning a, the engaging portion 11c of the hanging member 10 attached via a fastener 9b such as a nail is engaged with the fixing portion 10a to fix one end of the roof panel 10. The underwater side crest portion 10b is fitted with the fixing portion 10a fixed via the adjacent hanging member 10 located on the lower side, so that the roof plate 10 is sequentially roofed in the ridge direction.

The joints of the both side edges of the shingle 10 are such that adjacent side edges are more closely connected to each other on the covering plate 1 attached to the rafter 7 by a spliced structure. In addition, instead of using the construction method, it is also possible to arrange a receiving plate of a water draining plate on the covering plate 1, butt the adjacent roof plates 10, 10, and separately combine a joint cover or the like to perform rain. Regardless of the construction method,
As shown in FIG. 12, the arrangement position of the shingle 10 is shifted by one step, and the stitching is performed so that the seams are staggered. Further, in the case of the roof plate 25 shown in FIG. 9, the roof plate 25 is roofed by fixing the curved fixing portion 10d on the water side by the hanging member 11.

Instead of the roof shingles 10, 25, a flat roof structure using a stone slab or a ceramic flat plate 12, as shown in FIGS. 13 and 14, can be used.

In a roof with such a configuration, rainwater flows from the ridge toward the eaves, but even if rainwater infiltrates from the seam of the shingles 10 and 25 and stormwater spills on the back of the shingles 10 and 25, Is received by the covering plate 1 arranged in the area and flows toward the eaves. The rainwater that overflows the cover plate 1 flows from the drainage piece 1a to the inside of the water return piece 2a of the waterproof plate 2 and is collected, and the waterproof plate 2 acts as a rain gutter to guide rainwater toward the eaves and is drained. In addition, a roof having a waterproof structure that does not allow rainwater to accumulate in the roof and that does not leak is constructed. Rainwater on the cover plate is waterproof plate 2
In the case where water flows down, the water draining piece 1a is overhanging and the water return piece 2a of the waterproof plate 2 is formed, so that the rainwater can be prevented from being drawn in. Without leaking, it is possible to prevent the leakage of water, the loosing trees, and the corrosion of the base plate 8.

For this reason, it can be used for a roof having a gentle slope or a long flow such as a horizontal roof or a single-roof roof, which has been difficult in the prior art, and has a structure that can sufficiently cope with a roof in a snowy area or a rainy area.

〔The invention's effect〕

As described above, it is possible to support the conventional roof construction methods such as the commonly used metal horizontal roofing metal plate, single-roof metal plate, and stone roofing ceramic flat roofing plate. By using the roof base structure of the present invention,
It can be constructed without any special components other than the fasteners, and can be used to construct a roof with excellent waterproofness without any special skills. The rain can be simplified, and the shortage of craftsmen can be eliminated.

In addition, since the present invention is a combination of a cover plate and a waterproof plate, when installing an accessory such as a light or a ventilator on a roof plate, the installation is simplified, and the ridge, the keraba, and the arrangement of the arrangement are simplified. .

In addition, since a ventilation layer is formed between the roof shingle and the roof base plate, the roof has a ventilation structure that allows air to flow smoothly from the eaves toward the ridge. State can be maintained. Therefore, particularly easily corrosive members such as rafters, base materials, eaves, and keraba can be protected, and the roof surface has excellent dew condensation prevention, soundproofing, and heat insulation effects.
