[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.

[0003] On the other hand, from the viewpoint of simplifying the construction work of a wooden building, a panel in which plywood or the like is joined to both surfaces of a heat insulating material has been developed and put into practical use. If such a panel is formed with the plate materials on both sides having a certain strength, it is possible to construct walls, floors, etc. without using the structural members of wooden structures such as columns and joists that were required in the past. can do.

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 plate materials 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 plate members 3 on both sides are formed of the same member. Moreover, no consideration is given to the magnitude of the moisture permeability resistance of the plate material 3 and the moisture permeability resistance of the heat insulating material 2. Therefore, the moisture resistance of the heat insulating material 2 may be smaller than that of the plate material 3.

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 be radiated outward through the inner plate member 3 '. Therefore, water vapor may pass through the plate material 3 ′ and enter the heat insulating material 2.

However, when water vapor enters the heat insulating material 2 as described above, when the temperature becomes cold at night, the water vapor may be generated inside the heat insulating material 2 or at the contact surface between the heat insulating material and the outer wall on the back side. Condensation may occur.

In view of the above situation, the present invention can prevent the occurrence of dew condensation in the panel, can maintain an appropriate heat insulating effect for a long period of time, and is a structural multi-function panel suitable as a constituent material for walls, floors, roofs, etc. Is intended to provide.

[0011]

[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 A moisture-proof layer that does not allow water vapor to pass through is formed between the one structural plate member and the heat insulating member.

[0012]

[Action]

 According to the above configuration, even if water vapor enters the plywood of the panel from the inside of the room, the water vapor impinges on the moisture-proof layer when it passes through the plate material and is prevented from further permeating. This prevents water vapor from penetrating into the heat insulating material.

Therefore, even if such a panel is used for a long period of time, there is no risk of dew condensation within the panel, which can contribute to the provision of a highly heat-insulated building having excellent airtightness.

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, rectangular structural plywoods 12 and 13 attached to both surfaces of the heat insulating material 11, and one structural plywood 13 and the heat insulating material 11. It is composed of a moisture-proof layer 21 interposed therebetween.

The plate-shaped heat insulating material 11 is made of synthetic foam resin such as expanded polystyrene, expanded polyurethane, and expanded polypropylene. In addition, as another heat insulating material having a predetermined heat insulating performance, for example, a quasi non-combustible material composed of a foam containing a vinyl chloride resin or a chlorinated vinyl chloride resin containing an inorganic filler as a main component is used. There is a heat insulating material. 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 a predetermined space S formed in the upper and lower portions in a state of standing in the longitudinal direction. That is, the length is set shorter than that of the structural plywoods 12 and 13. In addition, recesses 14 and 14 for inserting sub plates later are formed on the lateral end faces in the upright state, whereby the end faces are formed in a convex shape.

The structural plate members 12 and 13 are formed of the same material, and are, for example, structural plywood such as a chip board and a wafer board. The moisture-proof layer 21 is formed of, for example, a waterproof coating film layer having adhesiveness such as urethane resin. When such a resin is applied, its thickness is 0.5 to 1 mm or more. Other moisture-proof layers include plastic films such as polyethylene, biphenyl chloride, and vinylidene chloride. You may adhere | attach these films and form a moisture-proof layer. In that case, the thickness of the film is about 100 μ to 300 μ. Further, another moisture-proof layer may be formed by adhering an asphalt sheet having a thickness of about 1 to 2 mm. Alternatively, an aluminum foil, an aluminum vapor deposition film or the like having a thickness of about 30 to 100 μm may be attached. However, considering the process at the site, it is rational to apply urethane resin with adhesiveness.

On the other hand, in the embodiment, the moisture permeation resistances of the structural plate material 12 and the structural plate material 13 are set to be equal. 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 object that fits into the gap S provided above and below the panel 10.

After hitting the lower frame 17 as described above, the lower part of the panel 10 is sandwiched between the lower frame 17 and the panel 10 is aligned and erected. At that time, one structural plate member 13 on the side of the panel 10 on which the moisture-proof layer 21 is arranged is arranged inside the room, and the other structural plate member 12 is arranged outside the room.

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 may be applied between the sub plates 18 and 18 and the structural plate members 12 and 13. In this way, the panel 10 and the adjacent panel 10 are arranged side by side, and a wall that can bear the load by itself 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. As described above, when the panel 10 is used upright as a wall panel, the vertical compressive force can be borne by the structural plate members 12 and 13 on both sides.

Therefore, if the panel 10 is used as the wall material as in the present embodiment, no structural member such as a pillar is required at all, and when installing a window or the like, the panel 10 is installed at a predetermined place. A notch may be formed in advance 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.

If necessary, a stud member may be inserted into the panel at a corner portion of a building or a portion subjected to a vertical load. According to this embodiment formed in this way, even if water vapor permeates into the panel 10 from the indoor side through the plate material 13, the water vapor impinges on the moisture-proof layer 21 and does not permeate further. To be prevented.

Therefore, dew condensation does not occur in the panel 10. 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, in the above embodiments, the present invention is applied as a wall panel, but these panels can be used as a floor panel or a roof panel. When the panel 10 is used horizontally as a floor panel, the structural plate members 12 and 13 on both sides can bear the compressive force and the tensile force due to bending, and the shear force can be applied to the heat insulating member 11 and the structural plate members 12 and 13. Can be covered by

[0031]

[Effect of device]

 As described above, according to the multi-function panel of the present invention, even if water vapor enters the plate material of the panel from the inside of the room, the water vapor strikes the moisture-proof layer when passing through the plate material, and The above penetration is prevented. This prevents water vapor from penetrating into the heat insulating material.

Therefore, even if such a panel is used for a long period of time, there is no risk of dew condensation within the panel, which can contribute to the provision of a highly insulated building having excellent airtightness.

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.
