[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof panel for forming a roof of a wooden house.

[0002]

2. Description of the Related Art In a wooden house, a roof is formed by using roof tiles. The roof is supported by a rafter fixed on the "haze" of the wooden house. It is a ground plate that is used. A general one of the base plates was a simple plate material, but in order to improve the workability and add heat insulation / durability to the base plate, the applicant used a base plate 30 as shown in FIG. Many proposals have already been made in Japanese Patent Laid-Open No. 3-108123.

In this field panel 30, upper and lower side members, which are also called face members, are integrally formed on the upper and lower surfaces of a plurality of rafters 11, and a gap 40 is formed in a space formed between them. The heat insulating material 14 is provided. As a result, the field panel 30 itself has the field board 12, as compared with the case where the rafter is fixed on the “haze” 21 of the wooden house 20 and then the field board is fixed. Since the work of fixing the base plate is unnecessary and the rigidity is high, the heat insulating material 14 and the gap 40 are excellent in the heat insulating effect, and moreover, by making the gaps 40 continuous with each other, the dew condensation of the field panel 30 itself. It has various characteristics such as prevention. In the field panel 30 shown in FIG. 11, the room side air is circulated between the heat insulating material 14 and the upper side surface material through a ventilation space (not shown) formed in the heat insulating material 14. is there.

The field panel 30 having the above advantages
However, when using this to complete a roof, it must be done while also preventing rain leakage, so a large number of field panels 30 can be used as shown in FIG. After placing and fixing it on the top, the waterproof material was applied on top of it. However, the construction of this waterproof material is very troublesome, and if the construction is not done carefully, rainwater may leak from the gap between the waterproof materials.

Therefore, the inventors of the present invention have variously studied how to make full use of the heat insulating property and strength of this type of field panel, and also to have excellent waterproof property and to greatly improve the construction efficiency. As a result of repeated studies, the present invention has been completed.

[0006]

SUMMARY OF THE INVENTION The present invention has been made based on the above-described background, and the problem to be solved is to ensure the waterproofness of the roof structural material. The object of the present invention is to provide a roof panel with a simple structure that has sufficient heat insulation and strength as well as sufficient waterproofness and is easy to install.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the roof panel 10 according to the present invention will be described in detail with reference to each embodiment shown in the drawings.

First Embodiment FIG. 1 shows a roof panel 10 according to the first embodiment of the present invention. The roof panel 10 includes a plurality of rafters 11,
A base plate 12 fixed to the upper side of the rafters 11, a heat insulating material 14 formed between the rafters 11, a waterproof sheet 15, a corrugated sheet 16 and a roof material 17 which are sequentially integrated on the base plate 12. It is equipped with. That is, the roof panel 10 is composed of the rafter 11, the base plate 12, and the heat insulating material 14.
According to the conventional field panel 30 shown in FIG. 11, a substantially similar structure is constructed, and the waterproof sheet 1 is mounted on the field board 12.
5, the corrugated sheet 16 and the roof material 17 are integrated using a nail or the like. In this case, what is important is to shift one side of the roofing material 17 to the other so that one side of the corrugated sheet 16 is exposed and the roofing material 1
The other side of 7 is projected.

Since each rafter 11 determines the overall size of the roof panel 10 and guarantees the rigidity of the roof panel 10, as shown in FIG. They are arranged on both sides of the panel 10, and are so-called square members. In this embodiment, a plurality of (two in the present embodiment 1 and the following embodiments) rafters 11 are arranged at equal intervals between the pair of rafters 11 to obtain sufficient rigidity of the roof panel 10. ,
The shape is stabilized for facilitating the work of placing and fixing the beam 22 and the purlin 23. The space 13 may be opened on the lower end side of each rafter 11 as shown in FIG. 6, but a plate material may be integrated as shown in FIG. 7 or 8. And the heat insulating material 14 is formed between these rafters 11,
It is done as follows.

That is, as shown in FIGS. 9 and 10,
First, a plurality of necessary rafters 11 are arranged at predetermined intervals, and a constant space is formed between them by using a face material or the like, and a foaming resin material is injected into these spaces, for example. By doing so, the resin material as shown in FIG. 10 is integrally foamed and solidified between the rafters 11. When foaming and solidifying the resin material between the rafters 11, as shown in FIG. 9, by using a heat press machine having a predetermined pressing plate, the thickness of each heat insulating material 14 and the distance between the rafters 11 are increased. Positioning is performed. In this embodiment, as shown in FIG. 9 and FIG. 10, by arranging the pressing plate of the heat press machine so as to be substantially in the center of each rafter 11, it is fixed on each heat insulating material 14 and rafter 11. A space 13 which communicates with the upper and lower sides of the roof is positively formed between the roof plate 12 and the roof plate 12. By thus forming the heat insulating material 14 made of foamable synthetic resin between the rafters 11, the rafters 11 are integrated by the heat insulating material 14.

For the plurality of rafters 11 integrated by the heat insulating material 14 as described above, as shown in FIG.
The base plate 12 is integrated on the upper side thereof. The base plate 12 maintains the shape as the roof panel 10, and at the same time, the waterproof sheet 15, the corrugated sheet 16 and the roof material 1 are provided.
It also serves as a support member that supports 7 while securing the space 13.

The waterproof sheet 15 is mainly made of asphalt or polyethylene, for example, and is made of a material having sufficient moisture resistance or waterproofness.
It is integrated with nails etc. on the top. Further, the corrugated sheet 16 is formed of a waterproof material having a certain softness such as synthetic rubber, and as shown in FIG. 1, is formed as a continuous wave of a certain height. There is. The corrugated sheet 16 having a certain flexibility is formed by the roof member 17 fixed on the corrugated sheet 16.
This is to stably position the roof tiles arranged on the roof tile. Further, it goes without saying that the corrugated sheet 16 has concave grooves formed on the upper surface thereof, but these concave grooves are provided above and below in order to allow rainwater etc. flowing down into the concave grooves to flow into the gutter under the eaves. It is the one for the direction.

As shown in FIG. 1, both side edges of the waterproof sheet 15, the corrugated sheet 16 and the above-mentioned base plate 12 are integrated so as to be at the same positions as the edges of the rafters 11 on the left and right ends. However, the roof material 17 integrated on the corrugated sheet 16 is shifted in the lateral direction in the figure. In other words, the roofing material 17 has roof tiles directly arranged on it,
By shifting one side of the roofing material 17 to the other, one side of the corrugated sheet 16 is exposed and the other side of the roofing material 17 is projected. In this way, by fixing the roofing material 17 on the corrugated sheet 16 while shifting the roofing material 17 to one side, each roofing material 17 is provided with respect to the roof panel 10 which is already applied as shown by the phantom line in FIG. That is, the boundary line of the above is placed on the other roof panel 10.
It should be noted that the roofing material 17 is advantageous as long as it has a predetermined rigidity and a certain degree of waterproofness, and in this embodiment, cement is the main material.

In the roof panel 10 according to this embodiment, as described above, the space 13 in the vertical direction is formed between the base plate 12 and the heat insulating material 14. Regarding this space 13, a wooden house It is of various shapes depending on the ventilation method applied to 20. That is, in order to insulate the roof panel 10 itself and prevent dew condensation, the upper and lower ends of each space 13 are opened to the ridge side and the eaves side, as shown in FIG. When it is desired to apply the so-called “building ventilation” to the wooden house 20 as shown in FIG. 7, the lower side of each space 13 is opened to the back side of the shed and the upper part of each space 13 is set to the building side. Opening is also performed. Further, in the case shown in FIG.
It is also possible to open both the upper and lower parts of the above to the back side of the hut of the wooden house 20, respectively.

Second Embodiment FIG. 2 shows a partial perspective view of a roof panel 10 according to a second embodiment of the present invention, which does not have the space 13 described above. Other than that, the roof panel 10 is the same as the roof panel 10 of the first embodiment. In other words, in this roof panel 10, the heat insulating material 14 is formed in a state in which the space between the rafters 11 is completely filled, whereby sufficient heat insulating property and integration of the waterproof sheet 15 and the like can be performed more reliably. It was done like this.

Since the respective constituent members of the roof panel 10 of the second embodiment are the same as those of the first embodiment, the same members in FIG. 2 are designated by the same reference numerals and the description thereof will be omitted.

Third Embodiment FIG. 3 shows a roof panel 10 according to the third embodiment of the present invention. The roof panel 10 is similar to the first embodiment except that the space 13 in the first embodiment is formed between the rafters 11 and in the lower portion of the heat insulating material 14. The description of the members will be omitted by giving the same reference numerals to those in the first embodiment in FIG.
