Description

[Detailed explanation of the idea] 〔Technical field〕 The present invention relates to a roof structure.

[Background Art] Asphalt-based roof base materials have been conventionally used as roof base materials constituting roof structures.

This product lacks water absorption and hygroscopicity, and has low ventilation, so there is a high risk of condensation.
This causes corrosion and rain leakage, the nails 7 for fixing the tile beams 11 tend to rust, making it difficult to fix the tile beams 11, and the ventilation of the roof itself deteriorates.

[Purpose of invention]

The present invention has been proposed in view of the above points, and since it has water absorption and hygroscopicity as well as a certain degree of breathability, it does not cause dew condensation, and it prevents water from accumulating in the tile sill. To provide a roof structure which does not corrode and has a structure in which the upper and lower surfaces of a roof base material body have good ventilation.

[Disclosure of invention]

Embodiments of the present invention will be described below with reference to the drawings.

1 in the figure is the main body of the roof base material, which is a structural member constituting the roof structure of the embodiment of the present invention, which is made of crushed waste paper, an appropriate amount of binder, water repellent, cotton waste, The shape shown in the figure is obtained by pressure molding a material obtained by mixing reinforcing agents such as fiber waste and wood flour.

To explain the shape of this roof base material body, there is a protrusion 2 in the center that protrudes toward the upper surface side and forms a groove 3 on the lower surface in the mushroom raising direction, and one side edge is provided with a protrusion 2 that extends upward by the thickness of the protrusion 2. Furthermore, a semicircular drainage groove 5 is provided on the upper surface of the other end.

These are all formed over the entire length.

Furthermore, a large number of protrusions 6 are provided on the flat part of the upper surface for the support of the tile beams 11, and the upper ends of these protrusions 6, the upper surfaces of the protrusions 2 and the upper surfaces of the stepped portions 4 are flush with each other. ing.

The roof base material main body 1 is fixed on the roof board 10 with a nail 7 driven from the upper end of the protrusion 6 so that the drainage groove 5 and the protrusion 2 are in the same direction as the slope of the roof. A stepped portion 4 is stacked on top of the roof base material main body 1.

In addition, 8 in the figure is a drainage groove provided in the part where another roof base material main body 1 to be roofed on the ridge side is overlapped.

In this way, after installing the roof base material body 1, the protrusion 2
The tile beam 11 is fixed so as to be perpendicular to the ridge 2, which forms a space between the roofing board 10 and the roof board 10 on the lower surface.
Since the stepped portion 4 is placed above the rafter 12, the nails 9 for fixing the tile beam 11 are driven through the protrusion 2 and the stepped portion 4 from the roof board 10 to the rafter 12. .

Between the shedding board 10 and the roof base material main body 1, a space formed by a groove 3 or a step 4 on the lower surface of the protrusion 2 ensures ventilation between the two,
In addition, the entire lower surface of the tile beam 11 does not come into contact with the roof base material body 1 due to the protrusions 2, steps 4, and protrusions 6, and drainage performance in this area is good. This prevents corrosion, leakage of rainwater, and rusting of the nails 9 for fixing the tile beams 11.

[Effect of idea]

As mentioned above, the present invention is not made of so-called asphalt-based material, but is made of a mixed material of crushed waste paper, an appropriate amount of binder, water repellent, and reinforcing agent such as fiber waste, cotton waste, and wood flour. The main body of the roof base material is formed by the roof base material, and many protrusions are protruded from the flat part, so there is a space between the tile beams and the parts other than the protrusions, and it has water absorption and moisture absorption properties, as well as ventilation. Therefore, there is no condensation on the underside of the tiles, and even if condensation does occur, there is plenty of space in areas other than grooves and protrusions. It has good ventilation, so the tiles do not corrode, the nails used to fix the tiles are hard to rot, and they are hard to slip, making roofing work easy. Furthermore, since the main material is waste, it is inexpensive. This has the advantage of being

In addition, a protrusion with a concave groove formed on the lower surface is integrally provided at the center of the upper surface of the roof base material body by the thickness thereof in the roofing direction, and one end of the roof base material body is raised by the thickness. Since the stepped portion is formed parallel to the protrusion, when the main body of the roof base material is installed, the step overlaps the other end of the adjacent roof base material body, making it easy to install the main body of the roof base material. Not only can it be used for roofing, but the space created by the grooves and steps on the lower surface of the ridges ensures ventilation between the roof base material itself, which is fixed on top of the roof board, and the roof board. Nails that are driven into the protrusions and steps have good ventilation due to the above-mentioned voids, so they have the advantage of preventing rust, etc. The entire bottom surface of the tile beam fixed to the top side of the roof base material body does not come into contact with the roof base material body, so drainage in this area is good, preventing corrosion of the tile base material, leakage of rainwater, and damage to the tile base material. This has the advantage of not causing rusting of fixing nails.

Furthermore, the upper surface of the protrusion and the upper surface of the stepped portion are used as the road surface, and the other end of the roof underlayment body adjacent to the lower side of the stepped portion of the roof underlayment body is arranged, and the roof underlayment material that is installed is Since the tile crosspiece is arranged on the top surface of the main body, even if the tile crosspiece is placed on the top surface of the roof underlayment material after the roof underlayment main bodies are installed side by side, the roof underlayment will not rattle. This has the advantage that it can be placed in the main body.
