[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multi-functional structural panel.

[0002]

[Prior art]

 In wooden structures and the like, heat insulating materials made of expanded synthetic resin are widely used in order to enhance the airtightness and heat insulating properties inside the buildings.

On the other hand, from the viewpoint of simplifying the construction work of a wooden building, a panel made by joining plate materials such as plywood to both sides of a heat insulating material has been developed and put into practical use. If such a panel is formed with plywood on both sides having a certain strength, it is possible to construct walls, floors, etc. without using the structural members of wooden construction such as columns and joists that were required in the past. You can do it.

Further, according to the construction method using such a panel, not only these structural members can be omitted, but also the assembling is easy and almost no carpentry skill is required, the construction period can be shortened, and the panel can be consistently manufactured. There is an advantage that the cost can be reduced by the production.

FIG. 5 shows such a conventional multi-functional structural panel. In this panel 1, a heat insulating material 2 made of expanded polystyrene is used as a core material, and plywoods 3 and 3 having a predetermined strength are attached to both surfaces thereof.

When the panels 1 and 1 are matched with each other, as shown in FIG. 6, the end portions are abutted with each other, and the sub plates 4 and 4 are inserted into the gap of the heat insulating material 2 so that both the panels 1 and 2 are joined together. The spaces are joined.

[0007]

[Problems to be solved by the device]

 By the way, in such a panel 1, the plywoods 3 and 3 on both sides are formed of the same member. Further, the size of the moisture permeability resistance of the plywood 3 and the magnitude of the moisture permeability resistance of the heat insulating material 2 are not considered at all, and in some cases, the moisture permeability resistance of the plywood 3 may be larger than that of the heat insulating material 2. there were.

Therefore, when such a panel 1 is incorporated into a building, there are the following problems in winter and the like. That is, in winter and the like, the indoor side is hotter and more humid than the outdoor side. Therefore, the water vapor on the indoor side tends to radiate outward through the plywood 3'on the inner side. However, if the moisture permeability resistance of the plywoods 3 ′, 3 is larger than that of the heat insulating material 2, the water vapor remains inside the heat insulating material 2 and cannot diffuse outward. Therefore, there is a fear that water vapor will be condensed in the heat insulating material 2 at night when the temperature is cold.

Further, if the water vapor condenses on the boundary between the plywood and the heat insulating material, the adhesive layer between the two may be destroyed and may be peeled off. In view of the above-mentioned circumstances, the present invention prevents damage to the heat insulating material in the panel due to dew condensation, has no fear of peeling the adhesive layer, can maintain an appropriate heat insulating effect for a long time, and can be used for walls, floors, roofs, etc. The purpose is to provide a suitable structural multifunctional panel.

[0010]

[Means for Solving Problems]

 The present invention for achieving the above object is provided with a plate-shaped heat insulating material made of a foamed synthetic resin and structural plate materials attached to both sides of the heat insulating material, and the end portions of the heat insulating material are abutted against each other on a base and arranged. In this way, a multi-functional structural panel that can form a self-supporting building wall and that can construct a ceiling or floor that can bear the load by itself by arranging the ends of the building to abut against each other The moisture vapor resistance of the structural plate material is set to be smaller than the moisture vapor resistance of the heat insulating material.

[0011]

[Advantageous Effects] According to the above configuration, even if water vapor enters the plate material of the panel from the indoor side, the water vapor passes through the plate material, passes through the heat insulating material, and further passes through the other plate material to the outside. There is no risk of water vapor remaining in the panel as it is directed to diverge.

Therefore, even if this panel is used for a long period of time, there is no risk of dew condensation on the heat insulating material or the adhesive layer, which can contribute to the provision of a highly insulated building having excellent airtightness.

[0013] Further, since this panel itself becomes a constituent material for walls, floors, roofs, etc., when it is used as a wall panel, for example, structural members such as columns and studs become unnecessary, and carpentry skills are improved. It can be made almost unnecessary and the construction period can be shortened.

Further, it is possible to freely design by combining the panels.

【Example】

 The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 shows a multi-function panel 10 according to an embodiment of the present invention.

The multifunctional panel 10 includes a plate-shaped heat insulating material 11 and rectangular structural plate materials 12 and 13 attached to both surfaces of the heat insulating material 11. The plate-shaped heat insulating material 11 is made of synthetic foam resin such as expanded polystyrene, expanded polyurethane, and expanded polypropylene.

Further, as another heat insulating material having a predetermined heat insulating performance, for example, a quasi non-combustible material made of a foam containing a vinyl chloride resin or a chlorinated vinyl chloride resin containing an inorganic filler as a main component. There is a heat insulating material composed of. In this case, not only the heat insulation performance, but also the fire resistance performance and light weight are excellent. Further, the other heat insulating material may be a heat insulating material formed of, for example, acrylic resin, vinyl chloride, phenol resin, or the like. In short, the material is not limited as long as it is a synthetic resin having a heat insulating property. Moreover, the expansion ratio is arbitrary.

The plate-shaped heat insulating material 11 has predetermined voids S, S formed in the upper and lower portions in a state of standing upright in the longitudinal direction. That is, the length is set shorter than that of the structural plate members 12 and 13. Further, recesses 14, 14 for inserting the sub plates later are formed on the lateral end face in the upright state, whereby the end face is formed in a convex shape.

The structural plate members 12 and 13 are made of the same material, and are, for example, structural plywood such as a chip board and a wafer board. In the embodiment, for example, the moisture permeation resistances of the structural plate member 12 and the structural plate member 13 are set to be equal. Further, when the moisture permeation resistance of the structural plate members 12 and 13 is P ₁ and the moisture permeation resistance of the heat insulating material 11 is P ₂ , these are preset such that P ₁ <P ₂ .

A plurality of panels 10 formed in this way are prepared and can be used as wall panels, for example, as shown in FIG. That is, the floor material 16 is arranged on the foundation 15. This floor material 16 may also be constructed from the panel 10.

Further, the lower frame 17 is struck on the upper portion of the floor material 16 with a nail or the like. The lower frame 17 is made of a long material that fits in the gaps provided above and below the panel 10. After such a lower frame 17 is struck, the lower portion of the panel 10 is sandwiched in the lower frame 17, and the panel 10 is aligned and erected.

When one panel 10 is placed in this manner, a structural adhesive is applied to the entire surface between the panel 10 and the adjacent panel 10 and, as shown in FIG. The plates 18,18 are inserted into the recesses 14,14. Next, as shown in FIG. 4, nails 20 are driven from the outside of the panel 10 at a predetermined interval to join the panels.

A structural adhesive is also applied between the sub plate 18 and the structural plate members 12, 13. In this way, the panel 10 and the adjacent panel 10 are arranged side by side, and the wall is constructed. Therefore, the wall can be constructed without using structural members such as columns, studs, and braces.

Further, an upper frame 19 of a long object is provided above the panel 10 like the lower frame 17. If necessary, studs may be inserted into the panel at the corners of the building or the parts that receive vertical load.

If the panel 10 is used as the wall material as in the present embodiment, structural members such as columns are not required at all, and if a window or the like is to be installed, a cut is made at a predetermined position of the panel 10 in advance. It may be formed beforehand and a window frame may be fitted in this portion. As a result, it is possible to easily perform processing such as opening on the spot.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made based on the technical idea of the present invention. For example, although the present invention is applied to the wall panel in the above embodiments, these panels can be used as a floor panel or a roof panel.

[0027]

[Effect of device]

 As described above, according to the multi-function panel of the present invention, even if water vapor enters the structural plate material of the panel from the indoor side, the water vapor will pass through the plate material and pass through the heat insulating material. Furthermore, since it is guided to diverge outward through the other plate, there is no fear that water vapor will remain in the panel.

Therefore, even when this panel is used for a long period of time, there is no risk of dew condensation on the heat insulating material or the adhesive layer, which can contribute to the provision of a highly heat insulating building having excellent airtightness.

Further, since this panel itself is a constituent material for walls, floors, roofs, etc., when it is used as a wall panel, structural members such as columns and studs become unnecessary, and carpentry skills are improved. It can be made almost unnecessary and the construction period can be shortened.
