Abstract

PROBLEM TO BE SOLVED: To obtain a roof backing structure having a long-term high property of waterproofing by arranging drain stiffeners, which are made of resin and have compression sealing property, on an underlaying material of a roof along a direction from eaves to a ridge, and by arranging stiffener across and on the drain stiffeners. SOLUTION: Drain stiffeners 3, which are made of resin such as polyethylene and have compression sealing property, are arranged on an underlaying material 1 of a roof along a direction from eaves to a ridge, and stiffener 4 are arranged across and on the drain stiffeners 3. Compression ratio of the drain stiffeners 3 is preferably between 30% and 80%. When rainwater leaks in from some place of a ridge side, the rainwater flows over the underlaying material 1 of the roof, and the drain stiffeners 3 do not decay because the stiffeners 3 are made of resin and have compression sealing property. Furthermore, when the drain stiffeners 3 are nailed to fix with the stiffener 4, compression sealing property of the drain stiffeners 3 takes effect to cover a circumference of a nail so that the rainwater is not transmitted down along the nail not to reach to a roof sheathing board provided under the underlaying material 1 of the roof. Therefore, long-term high waterproof performance is maintained.

FIGS. 1 to 3 show a roof base structure according to the present invention.
As shown in the figure, the roof underlaying material (1), the sinking bar (3) disposed on the roofing underlaying material (1) in the direction of the eaves ridge, and the crossing with the sinking crossover (3) Pier (3)
In the roof foundation structure provided with the crosspiece (4) disposed on the top, the sink crosspiece (3) is made of resin and has a compression seal property.

As shown in FIGS. 1 to 3, for example, the roof underlaying material (1) is laid on a field board (11), and is a waterproof sheet made of resin such as polyvinyl chloride. In addition, a sheet-like material in which a metal such as aluminum, steel, or stainless steel is used as a core material and coated with a resin such as polyvinyl chloride may be used.

As shown in FIGS. 1 to 3, the sink bar (3) is disposed on the roof underlaying material (1) in the direction of the eaves ridge. The sink bar (3) is made of resin and has compression sealing properties. Specifically, foamed polyethylene, foamed polypropylene, foamed acrylonitrile butadiene styrene and the like can be used. As shown in FIGS. 1 and 2, each climbing tree (5) may be provided at both ends in parallel with the sink bar (3).

As shown in FIGS. 1 to 3, the crosspiece (4) is provided so as to intersect with the crosspiece (3).
It is arranged above. As the crosspiece (4), a wooden one is usually used. In addition,
As shown in FIG. 1, a ridge (7) may be provided at the ridge end side in parallel with the pier (4).

As a fixing method, for example, FIG.
As shown in the figure, the nail (9) is driven,
Along with the crosspiece (4), the sink bar (3) is fixed to a base plate (11).

As shown in FIG. 2, a roof tile (8) is laid on the crosspiece (4). Examples of the roof tile (8) include a roof tile made of pottery, asbestos, asbestos cement, cement with fiber, synthetic resin, metal, or other known inorganic materials. As a shape of the roof (8), for example, as shown in FIG. 2, a corrugated roof tile is used.
A flat roof tile or the like may be used.
In addition, this roof tile (8)
The keraba tile may be used so as to cover the same climbing tree (5). The roof tile (8) is, for example, driven into a pier (4) by driving a nail (9).
It is fixed to.

In addition, the above-mentioned draining board (10)
As shown in FIG. 2, among the above-mentioned roof tiles (8), the roof tiles (8) are disposed below a portion between the roof tile and the main roof tile. As the draining board (10),
Plates made of metal such as aluminum, steel, and stainless steel that are commonly used, and plates made of metal such as aluminum, steel, and stainless steel and coated with a resin such as vinyl chloride resin. Is also good.

According to the present invention, by adopting such a configuration, even if rainwater or the like intrudes from a place on the ridge side,
A sink (3) which can be flown on the roofing material (1), and which is arranged on the roofing material (1) in the direction of the eaves ridge
Is made of resin and has compression sealing properties.
In the long term, the sinking bar (3) does not rot, and together with the bar (4) disposed on the same sinking bar (3) so as to intersect with the sinking bar (3), fixing of nails etc. When fixed by hitting the fixture, the sink bar (3) exerts the compression sealing property and is covered around the fixture, and as a result, rainwater and the like is transmitted along the fixture to the roof underlaying material (1). It does not reach the base plate provided underneath, and the waterproof property can be kept high in the long term.

That is, the present invention can improve the waterproofness over a long period of time.

Further, the compression ratio of the sinking bar (3) is 30
% Or more and 80% or less, it is possible to more effectively exhibit the compression sealing property, so that the sink (3) ensures that the periphery of the fixture is covered, and as a result, the fixture is fixed. Rainwater, etc., along the roofing material (1)
It does not even reach the ground plate provided underneath, so that the waterproofness can be maintained more reliably and for a long time.

If the compression ratio of the sinking bar (3) is 30
%, The compression ratio of the crossing bar (3) is too low,
That is, it is difficult to deform, and it is difficult to reliably cover the periphery of the fixture. On the other hand, if the compression ratio of the sinking bar (3) is more than 80%, the compression ratio of the sinking bar (3) is too high, that is, the sinking bar (3) is easily deformed, and the periphery of the fixture is surely secured. However, due to the ease of deformation of the sinking bar (3), it may shift around the fixture and form a gap, causing rainwater to infiltrate, and high waterproofness over the long term Being able to keep it is difficult.

The compression ratio is evaluated by the rebound resilience and can be checked by ASTM D1564.

Further, as shown in FIGS. 4 to 6, when the adhesive layer (6) is provided on the back side of the sink bar (3), the adhesive layer (6) on the back side allows the roof underlaying material (1). )
When the sink (3) is arranged in the direction of the eaves on the roof, it will not move on the roofing material (1) and will be temporarily fixed. The subsequent construction work, such as disposing, can be simplified. Moreover, the adhesive layer (6) ensures that the periphery of the fixture is covered in addition to the compression sealing property of the sinking bar (3), and consequently rainwater and the like are transmitted along the fixture to the roof underlaying material (1). It does not even reach the base plate provided underneath, so that the waterproofness can be maintained more reliably and for a long period of time.

As the adhesive layer (6), for example, a butyl-based material such as cellulose ether-based carboxymethylcellulose or methylcellulose, or a urethane-based acrylic urethane is used. In order to make effective use of this adhesive layer (6) during construction, release paper may be attached to the surface of the adhesive layer (6) during transportation or the like.

Particularly, the thickness of the pressure-sensitive adhesive layer (6) is 0.5
When it is not less than 2.0 mm and not more than 2.0 mm, the existence value of the adhesive layer (6) can be more effectively increased.
That is, when the sinking bar (3) is arranged in the direction of the eaves ridge on the roofing material (1) by the adhesive layer (6),
It will not move securely on the roofing material (1), and will be temporarily fixed, and as a result, it will be possible to reliably perform post-construction work such as arranging the pier (4). It can be simple. Moreover, in addition to the compression sealing property of the sink bar (3), the periphery of the fixture is reliably covered by the adhesive layer (6), and as a result,
Rainwater, etc., which does not reach the base plate provided under the roof underlaying material (1) along the fixing device, can be maintained more reliably, and the waterproofness can be kept higher in the long term. Becomes

If the thickness of the adhesive layer (6) is 0.5
When the thickness is less than mm, the adhesive layer (6) is too thin to sufficiently increase the value of the adhesive layer (6), and as a result, after the pier (4) is provided or the like. It is difficult to simplify the construction work, and moreover, it is difficult to maintain high waterproofness more reliably and for a long period of time. Conversely, when the thickness of the pressure-sensitive adhesive layer (6) is more than 2.0 mm, the existence value of the pressure-sensitive adhesive layer (6) can be more effectively increased.
The adhesive layer (6) becomes too thick, which makes it difficult to carry or work. Moreover,
Problems such as an increase in cost also arise.

As shown in FIGS. 5 and 6, the upper end (2) of the sinking bar (3) is formed in a pointed shape so that water can easily flow toward the eaves. And the pointed type makes it easier for rainwater and other water to flow into the eaves without allowing the water such as rainwater that has entered from a certain location on the ridge side to stay at the upper end (2) of the sink (3). Water such as rainwater that has entered the groundwork can be reliably discharged to the eaves, and as a result, the waterproofness can be maintained more reliably and for a long time.

In this case, the shape of the upper end portion (2) of the sinking bar (3) may be any shape such as slightly rounded as long as it is a pointed type. For example, as shown in FIG. 5, the upper end (2) of the sink bar (3) is formed so as to be inclined on both sides, or as shown in FIG. 6, the upper end of the sink bar (3) The tip (2) is formed so as to be inclined on one side.

Since it has a compression-sealing property, even if rainwater or the like intrudes from a location on the ridge side, it can flow on the roof underlaying material (1), and further, on the roof underlaying material (1). Since the sinking bar (3) arranged in the eaves ridge direction is made of resin and has a compressive sealing property, the sinking bar (3) does not rot even in a long term, so that the sinking bar (3) can be used. ) And nails and other fixing tools such as nails, which are placed on the same crossing bar (3) so as to intersect with When fixed, the sink bar (3) exerts the compression sealing property, and the periphery of the fixture is covered. As a result, rainwater and the like are provided under the roofing material (1) along the fixture. It does not reach the ground plate, and can maintain high waterproofness for a long time.

That is, the present invention can provide an excellent waterproof property for a long term.
