DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of an airtight joint structure according to the present invention will be described below with reference to the drawings. 1 to 4 show an example in which the airtight joint structure according to the present invention is applied to a heat insulating panel (field panel) 10 for constructing a roof of a wooden house in order to make the space behind the hut an airtight structure. As shown in FIG. 1, the heat insulating panel 10 is composed of a face material 11, a frame member 12 attached and fixed to one surface of the face member 11 at a predetermined interval, and a heat insulating material 13 filled between the frame members 12. They are laid so as to be joined to each other on the purlin 30 which is a frame of the roof and fixed by nailing. Here, the face material 1 of the heat insulation panel 10
Reference numeral 1 constitutes a base plate, and the frame member 12 constitutes a rafter. Plywood (for example, plywood, particle board, OSB, etc.) is used for the face material 11 of such a heat insulating panel 10, natural wood such as pine, cedar, and toga is used for the frame material 12, and heat insulating material 13 is used. For example, those formed of a foaming resin such as urethane resin, phenol resin, styrene resin, silicone resin, urea resin are used.
As the heat insulating panel 10, one having a space 14 for ventilation formed between the face material 11 and the heat insulating material 13 is used.

As shown in FIG. 2, a concave portion 15 opening to the front side is formed on the joint surface between the frame member 12 of one heat insulating panel 10 and the frame member 12 of the other heat insulating panel 10 which are joined to each other. Filling material 20 is filled in recess 15.
In this example, the side edges of the face material 11 and the side edges of the frame material 12 of both heat insulating panels 10 are partially cut away to form the recesses 15. As described above, it is preferable that the concave portion 15 is formed above the joint surface with the joint surface as the center, but the heat insulating panel 10 on one side is not formed.
The face member 11 and the frame member 12 of the other heat insulating panel 10 are left as they are, and only the face member 11 and the frame member 12 of the other heat insulating panel 10 are cut out to form the concave portion 15.
May be formed. Further, the recess 15 is preferably formed deeper than the thickness of the face material 11.
The reason for this is that the joint surface between the face material 11 and the frame 12 can also be structured so as to be shielded from the outside by the filler 20, and when the face material 11 is thin, airtightness is secured. This is because it is difficult to form the concave portion 15 that allows the filling material 20 to be filled sufficiently. In addition,
When forming the concave portion 15, the side edge of the face material 11 may be cut out, but the face material 11 having a width in which the concave portion 15 is formed may be prepared in advance and integrated with the frame 12.

As shown in FIG. 3, in the joint portion where the heat insulating materials 13 of the heat insulating panel 10 are bonded to each other, the heat insulating material 13 is formed.
And a part of the edge of the frame 12 is cut away to form the recess 1
5 is formed, and the filling material 20 is filled in the recess 15. Further, as shown in FIG. 4, in the roof ridge, the heat insulating panels 10 laid from both sides on the purlin 50 are joined to each other, and the same foaming property as the heat insulating material 13 is provided between the edges of the heat insulating material 13. Filling construction with resin 21 is performed.
As shown in FIGS. 3 and 4, the heat insulating material 13 of the heat insulating panel 10
In the joint portion where the two are joined, the recess 15 may be formed and the filler 20 may be filled in the recess 15 in order to fill the gap, and the foaming resin 21 of the same quality as the heat insulating material 13 is filled. You may go. In this example, the face material 11 is formed to be shorter than the length of the frame material 12, and the base plate 60 is attached later at the joint portion. This is for facilitating the filling of the filling material 20 into the recess 15 or the filling of the foaming resin 21 with ease and certainty.
In addition, in the heat insulating panel 10 in which the ventilation space 14 is not provided between the face material 11 and the heat insulating material 13, the concave portion 15 is formed in the joint portion to form the concave portion 15 without forming the back plate 60. It is possible to fill the filling material 20 in the inside 15.

As the filling material 20 filled in the recess 15, a sealing material made of silicone resin, acrylic resin or the like is used. In the present invention, as shown in FIG. 5, the filler 20 may be a combination of the sealing material 20a and the soft foam 20b. As the soft foam body 20b, for example, a soft urethane foam body is used. After the soft foam body 20b is filled in the recessed portion 15, the sealing material 20a is further filled therein to bend the heat insulation panel 10 made of wood. It is possible to allow the soft foam 20b to absorb the deviation and the like caused in the joint portion due to the above, and to stabilize the airtightness for a long period of time.

By adopting such an airtight joint structure of the heat insulating panel 10, an airtight attic space can be formed. In order to further improve the airtightness, for example, as shown in FIG. 6, a heat insulating panel 10 having a moisture-proof film 80 such as polyvinyl chloride resin or polyethylene resin attached to the back surface including the side edges of the frame 12 is used. May be. In addition, as shown in FIG. 7, the contact surface between the frame 12 and the heat insulating material 13 for the barrel support 70 mounted on the purlin 30 and the beam (not shown) where the joints between the heat insulating panels 10 are located. A sealing material 71 made of a soft urethane foam may be attached to.

The airtight joint structure according to the present invention includes the heat insulating panel used for constructing the roof of the wooden house shown in the above embodiment, which is the heat insulating panel used for constructing the wall, as well as the heat insulating panel used for constructing the wall. It can also be applied to wall panels, which are panels, and floor panels, which are insulation panels used to construct floors.

[0016]

As described above, according to the first aspect of the present invention, the above-described configuration facilitates the filling work of the filling material and fills the filling material enough to secure the airtightness. In addition, since the filler is enclosed in the recess, there is no fear that the filler will be lost during construction such as roofing tiles or outer wall finishing, and it is possible to reliably perform airtight construction. By forming an airtight attic space, etc., it is possible to effectively utilize the interior space of the wooden house.

Further, in the invention according to claim 2, since the filler is made of a soft foam and a sealing material,
The soft foam absorbs the displacement and the like generated at the joint portion due to the bending of the wood-based heat insulation panel and the airtightness can be stably maintained for a long period of time as compared with the case where only the sealing material is used as the filler.
