[Industrial applications]

 The present invention relates to a heat insulating panel installed on a wall, floor, roof or the like of a building.

[0002]

[Prior art]

 For wooden structures and the like, heat insulating materials made of synthetic foamed resin are often used in order to improve the airtightness and heat insulating properties inside the buildings.

In a wooden building, a heat insulating panel in which a heat insulating material is integrated with a stud, a rafter, or a plate member has been developed and put into practical use from the viewpoint of simplifying the construction work. If such a heat insulating panel is used as a wall panel, for example, the work of laying structural members such as braces can be omitted, and the cost can be reduced by the integrated production of the panel.

FIG. 7 shows an example of a heat insulating panel used for such various uses. That is, the heat insulation panel 1 includes a main timber 2 and heat insulation materials 3a and 3b made of synthetic foam resin, which are joined on both sides with the main timber 2 sandwiched between them, and one main surface side of which is large enough to cover all of them. The waterproof paper 4 is attached, and the waterproof paper 5a, 5b is attached to the other main surface side in a size to individually cover the heat insulating materials 3a and 3b.

If such a heat-insulating panel 1 is used as a wall panel, for example, since the main wood 2 is installed inside the panel in advance, it is possible to omit the on-site enforcement and to make it a panel. , Its attachability becomes good.

[0006]

[Problems to be solved by the device]

 However, in the above conventional heat insulation panel, although the heat insulating material is arranged on both sides of the main wood, the back surface of the main wood is only waterproof paper and no heat insulating material exists. Since the heat insulation performance was not sufficient, it was not possible to construct a building with a uniform and sufficient heat insulation structure by using this heat insulation panel as a wall panel. Moreover, the joint strength between the main wood and the heat insulating material is generally weak, and in particular, when a force such as twisting acts, the main wood and the heat insulating material may easily separate from the joint. There was a point.

In view of the above, the present invention has sufficient heat insulation performance to maintain high airtightness and heat insulation indoors, and enhances the joint strength between the main wood and the heat insulating material, The purpose is to provide a heat-insulating panel that does not easily separate.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the heat insulation panel according to the present invention has main wood such as studs, rafters, joists, floor boards, and ground boards on at least one main surface of a substantially rectangular heat insulating material made of synthetic foam resin. It is characterized in that a side end portion along the length direction of the main wood is embedded and arranged inside the heat insulating material.

Here, the heat insulating material has a multi-layered structure composed of two or more layers of synthetic foamed resin, or the side edge portions of other heat insulating material panels disposed at positions adjacent to both side edge portions of the heat insulating material. It is also possible to form a concavo-convex fitting portion that fits with each other.

[0010]

[Action]

 According to the present invention configured as described above, since the heat insulating material is also arranged on the entire back surface side of the main timber, not only the heat insulating performance can be exerted all over the panel, but also the main timber. By joining the main wood with the heat insulating material on the three surfaces of the buried portion of the main wood into the heat insulating material, it is possible to increase the bonding strength here and prevent the two from being easily separated.

Moreover, by making the heat insulating material a multi-layered structure composed of two or more layers of synthetic foamed resin, the main wood is placed on at least one layer side for facilitating the burying, and both side ends of the heat insulating material. By providing a concavo-convex fitting part on the part and connecting adjacent panels via the fitting part, it is possible to improve the installation workability and prevent the inflow of air at the connecting part by the labyrinth effect.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show a first embodiment of a heat insulating panel according to the present invention. A heat insulating panel 10 is a substantially rectangular heat insulating material 11 made of synthetic foam resin and one of the heat insulating material 11 The main wood 12 is arranged on the main surface 11a side with its side end portion buried.

The main wood 12 is located substantially at the center in the width direction of the heat insulating material 11 and extends over almost the entire length in the length direction of the heat insulating material 11. About half of the cross section is embedded inside the heat insulating material 11. It is placed in a closed state, that is, with about half of its cross section exposed to the outside.

In this way, by constructing the heat insulating panel 10 by integrating the main wood 12 with the heat insulating material 11, it is possible to improve the workability of attachment to a frame or the like, and to use the heat insulating material made of synthetic foam resin. By setting the thickness of 11 appropriately, sufficient heat insulating performance can be exhibited, and further, the main wood 12 is joined to the heat insulating material 11 at three surfaces of the main wood 12 embedded in the heat insulating material 11. By holding it, the heat-insulating material 11 and the main wood 12 are strengthened in joint strength so that they are not easily separated from each other.

Specific examples of the material of the heat insulating material 11 include foamed polyurethane and foamed polypropylene. As another heat insulating material having a predetermined heat insulating performance, there is, for example, a heat insulating material made of a material having a semi-incombustibility or higher containing an inorganic filler. In this case, not only the heat insulation performance, but also the fire resistance performance and light weight are excellent. Further, as another heat insulating material, for example, there is a heat insulating material formed of acrylic resin, vinyl chloride, phenol resin or the like. In short, the synthetic foamed resin having the heat insulating property may be used, and the material is not limited at all. Moreover, the expansion ratio is arbitrary.

A plurality of heat insulating panels 10 having such a configuration are prepared, and can be used as wall panels, for example, as shown in FIGS. 2 and 3. When used as a wall panel, the heat insulation panel 10 is laid as shown in FIG. That is, the foundation 14 is provided on the foundation 13, and the through columns 15 and the studs 16 are provided on the foundation 14. A body difference 17 and a girder 18 are provided between these columns 15 and 16.

In order to fix the heat insulating panel 10, first, the end portions of the main wood 12 are fitted into the grooves provided in the base 14, the body difference 17, the girder 18, etc., and the end surfaces of the adjacent heat insulating panels 10, 10 are joined to each other. Match each other. Then, the periphery of the heat insulating panel 10 is fixed to the base 14, the body difference 17, and the girder 18 with nails or the like. As a result, the laying of the heat insulation panel 10 is completed.

Further, as shown in FIG. 3, a vertical copper edge 19 is provided on the other main surface side of the heat insulating material 11, and an exterior material 20 is provided on the outer side of the vertical copper edge 19, while airtightness is provided on the inner sides of the through columns 15 and the studs 16. The waterproof seal 21 and the interior material 22 are laid respectively.

In this way, when the heat insulation panel 10 is installed as a wall panel, the inner ventilation layer 23 is provided between the heat insulation material 11 and the interior material 22, and the outer ventilation layer is provided between the heat insulation material 11 and the exterior material 20. 24 are formed respectively. Therefore, when a solar system is installed, the inner ventilation layer 23 allows warm air to pass through in the winter, and the outer ventilation layer 24 allows cold air to pass through during the summer. .

In the heat insulating panel 10, an airtight member may be interposed between the outer peripheral edge on the one main surface 11a side of the heat insulating material 11 and the side end surface that is the contact surface with the adjacent heat insulating panel.

As described above, when the airtight member is interposed between the outer peripheral edge and the side end surface of the heat insulating panel 10, the heat insulating material 11 and members abutting on the heat insulating material 11, that is, the through columns 15, the studs 16, the body gap 17, the girders, the girders. The airtightness between the heat insulating panels 10 and the like can be maintained, and the airtightness between the adjacent heat insulating panels 10, 10 can be maintained. Therefore, no gap is formed in these parts, and it is possible to keep the inside of the room highly airtight and highly insulated.

The case where the heat insulating panel 10 according to the embodiment of the present invention is used as a wall panel has been described above. However, the present invention is not limited to the above embodiment, and the heat insulating panel 10 is used as a roof panel or a floor panel. Of course, you can do that.

Further, flexible face materials may be attached to both main surfaces of the heat insulating material 11. Specific examples of the face material include paper, plastic, inorganic paper, non-woven fabric and the like. By sticking such a flexible face material, the strength of the heat insulating material 11, especially the bending strength can be improved.

It should be noted that, in the above-mentioned embodiment, an example in which the furring strip 19 is struck after the heat insulating panel 10 is installed is shown. However, auxiliary wood such as the furring strip 19 is previously joined to the heat insulating panel 10. You may stay. Further, the length of the main wood 12 can be set longer or shorter than the length of the heat insulating material 11, or the main wood 12 can be arranged diagonally like a bracing.

FIG. 4 shows a second embodiment. The difference of this embodiment from the first embodiment is that the heat insulating material 31 is made of the first synthetic foam resin 31a and the second synthetic foam resin. 31b has a two-layer structure consisting of two layers, and the main wood 12 is sandwiched between the second synthetic foamed resin 31b from the left and right, that is, the surface of the first synthetic foamed resin 31a and the second synthetic resin 31a. The main wood 12 is placed in a recess formed by the end faces of the foamed resins 31b, 31b, and the three surfaces of the main wood 12 are bonded to the respective surfaces of the recess, so that the main wood 12 is embedded inside the heat insulating material 31. The point is that the heat insulating panel 30 is configured.

With this structure, the main wood 12 can be embedded in the heat insulating material 31 by, for example, bonding, and this embedding can be facilitated to facilitate the production of the heat insulating panel 30. Can be planned.

FIG. 5 shows a third embodiment. The difference from the first embodiment of this embodiment is that the heat insulating material 11 has concave-convex fitting at both end portions parallel to the main wood 12. The parts 11b and 11c are formed to form an interleaving structure, and the airtight member 32 is provided on the peripheral portion on the one main surface 11a side of the heat insulating material 11 and the surfaces of the concave and convex fitting parts 11b and 11c. That is, the heat insulating panel 40 is configured.

With this configuration, it is possible to connect the heat insulating panels 40, 40 arranged at the positions adjacent to each other while fitting them through the concave and convex fitting portions 11b, 11c, and thereby, A labyrinth portion can be formed in the connecting portion to ensure airtightness in the connecting portion.

The airtight member 32 is preferably a sealing tape having elasticity and adhesiveness. An example of this is a tape that uses a soft vinyl chloride foam made of closed cells as a base material and has an adhesive and a release paper on one side. Specifically, a product name of Kanefuchi Chemical Industry Co., Ltd. Banshiru ".

By thus interposing the airtight member (sealing tape) 32 having an elastic force, it is possible to prevent the occurrence of a gap for a long period of time. Therefore, according to the heat insulation panel 40 thus formed, when used as a wall panel, the airtightness and heat insulation at the time of installation can be further improved. Moreover, since the concave and convex fitting portions 11b and 11c are matched with each other, the mounting workability is improved. Moreover, the inflow of air can be prevented by the labyrinth effect in the uneven fitting portions 11b and 11c. Further, even if the moisture of the wood evaporates with the passage of time and the wood becomes thin, no gap is exposed at that portion and the airtightness is not deteriorated.

FIG. 6 shows a modified example of the third embodiment. In addition to the main wood 12 on the one main surface 11a side of the heat insulating material 11, the main wood 12 is crossed with the main wood 12 and braces. As described above, the second main lumber 33 running diagonally is joined. Thus, by joining the second main lumber 33 in addition to the main lumber 12, it is possible to enhance the strength of the panel.

It is needless to say that the side end portion of the second main wood 33 can be embedded inside the heat insulating material 11 to enhance the joint strength.
