DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 7, a roof panel 10 of a wooden house according to an embodiment of the present invention is attached to a girder 11, a main house 12, a purlin 13 and the like, which are shaft members serving as a shaft assembly of the roof portion of the wooden house. Fixed. The girder 11 is hung between the pillars 14, and the purlin 12 and the purlin 13 are supported by a shed bundle 15 provided on a beam (not shown) on the back of the shed.
[0009]
The roof panel 10 of this embodiment includes a pair of structural plywoods 21 and 22 facing each other, and a support member 23 that integrally connects the structural plywoods 21 and 22 with a predetermined interval therebetween. The support members 23 are respectively disposed on both side edges in the longitudinal direction of the structural plywoods 21 and 22 and are not provided on the other side edges. Further, a support member 24 for separating the structural plywoods 21 and 22 at a height equal to that of the support member 23 is provided integrally with the structural plywoods 21 and 22 along the longitudinal direction of the structural plywoods 21 and 22. It has been.
[0010]
Between the pair of structural plywoods 21 and 22, a heat insulating material 26 is fixed to the back surface of one structural plywood 22. The thickness of the heat insulating material 26 is thinner than the distance between the pair of structural plywoods 21 and 22, and an air passage 28 is formed between the structural plywood 21 and the heat insulating material 26. The air passage 28 communicates from one end of the structural plywood 21 and 22 to the other end.
[0011]
On one end surface of the structural plywoods 21 and 22 and one end surface orthogonal thereto, a ridge 30 is formed along the longitudinal direction. The other end surface of the structural plywoods 21 and 22 and the other end surface orthogonal thereto Is provided with a concave groove 32 formed along the longitudinal direction and into which the ridge 30 can be fitted. A resin or rubber sealing material 34 is disposed in the concave groove 32 along the longitudinal direction.
[0012]
As shown in FIG. 6, the structural plywood 22 on the side to which the heat insulating material 26 is attached is formed with a through hole 36 communicating with the back space of the outer wall material 40 of the house in the construction state. The through hole 38 formed in the thickness direction of the heat insulating material 26 communicates with the through hole 38 of the heat insulating material 26 and communicates with the air passage 28.
[0013]
Further, as shown in FIG. 3, the support member 23 located at the eaves of the roof panel 10 spans the support members 23 adjacent to each other, and the roof panel 10 is attached to the building in a state of being attached to the building 11. A wooden bracket 42 is attached to be fixed. A through-hole 44 is formed in the structural plywoods 21 and 22 and the heat insulating material 26 at the mounting position of the bracket 42 so as to penetrate in the thickness direction. As shown in FIG. 7, the bracket 42 is formed in a U-shape, and a through hole 45 for fixing to the support member 23 is formed in the upper surface portion, and both ends of the U-shape are in the longitudinal direction. The shaft 46 is twisted by 90 ° about the shaft, and a through hole 46 for fixing to a shaft member such as the beam 11 is also formed on the tip side of the twisted portion.
[0014]
An eaves edge frame material 48 is provided at the eaves edge of the roof panel 10 to hide the heat insulating material 26 and the air passage 28. Note that the eaves edge frame member 48 may be formed with a through hole or a groove for allowing water droplets that have flowed through the air passage 28 to escape to the outside.
[0015]
In the roof panel mounting structure of the wooden house of this embodiment, the roof panel 10 is mounted and fixed on a girder 11, a purlin 12, a purlin 13 and the like, which are shafts. At that time, a paddle 52 is inserted and fixed between the girder 11 and the like along the inclination of the roof panel 10. Further, an airtight material 50 is inserted along the longitudinal direction between the paddle 52 and the structural plywood 22 of the roof panel 10. Similarly, a purlin 54 is placed on the purlin 13, and an airtight member 50 is inserted between the purlin 54 and the roof panel in the longitudinal direction.
[0016]
The roof panel 10 is provided with a recessed portion 26a obtained by cutting out the heat insulating material 26 at one end portion, and a nail 56 is driven from the recessed portion 26a into the purse 52 and the purlin 54, and further driven into the purlin 12 and the purlin 13 for fixing. Is done. A heat insulating material 26b is inserted into the recess 26a to maintain heat insulation. In the upper part of the building, there is provided a building ventilation section 60 that communicates with the air passage 28 and communicates with the outside air.
[0017]
The roof panel of the wooden house according to this embodiment is configured such that the air passage 28 of the roof panel 10 passes through the through holes 36 and 38 from the space inside the outer wall material 40 of the house by the air passage 28 formed outside the roof panel 10. The air flow to the building ventilation section 60 at the top of the building is possible, and the roof portion is burned and the roof panel 10 is prevented from being condensed. In addition, the connecting portion between the roof panels 10 has high airtightness and heat insulating properties because the ridges 30 and the grooves 32 are fitted and the sealing material 34 is interposed. In addition, since the airtight member 50 is interposed between the roof panel 10 and the wooden boards 52 and 54, higher airtightness performance can be maintained.
[0018]
In addition, the roof panel 10 is securely fixed to the girders 11 by the wooden fittings 42 and has a high strength that can withstand strong winds such as typhoons. Furthermore, since the heat insulating material is continuously arranged also in the roof panel 10 of the portion protruding from the eaves, it has high strength against the bending load of the eaves. On the outdoor side of the through-hole 44, after the skirting bracket 42 is mounted, it may be closed by applying taping for airtight and watertight.
[0019]
In addition, the roof panel of this invention is not limited to the said embodiment, A solar panel may be integrally provided by replacing the roof panel with the structural plywood on the air passage side. Thereby, an air passage contributes also to cooling of a photovoltaic power generation panel. Moreover, the photovoltaic power generation panel may be laminated and integrated with the roof panel. Furthermore, a solar panel that uses solar heat for hot water supply or the like may be provided integrally with the roof panel of the present invention.
[0020]
A heat reflecting material such as a metal foil or a metal vapor deposition film may be provided on the surface of the heat insulating material facing the air passage. This further improves the heat insulation performance and prevents the roof panel portion from being burned. In addition, a waterproof sheet is provided in advance on the structural plywood located on the outdoor side of the roof panel, and the waterproof sheet is in a state where the peripheral edge protrudes from the roof panel, and the waterproof sheets between adjacent roof panels overlap each other. You may make it stick together. Thereby, waterproof performance can be ensured reliably.
[0021]
【The invention's effect】
The roof panel mounting structure of the present invention facilitates the mounting of the roof base material, and can easily form a roof structure with high airtightness and heat insulation properties. In addition, the strength can be high, and high wind pressure resistance and snow resistance can be provided even in regions where strong winds blow or in heavy snowfall areas. Moreover, since the structural plywood of the roof panel is integrally fitted and connected by unevenness, they are integrated with each other and have high strength.
