BACKGROUND OF THE INVENTION The present invention relates to a multifunctional structural panel.

[0002]

2. Description of the Related Art In a wooden building or the like, a heat insulating material made of a foamed synthetic resin or the like is widely used in order to enhance the airtightness and heat insulating property inside the building.

[0003] On the other hand, from the viewpoint of simplifying the construction work of a wooden building, a panel made by joining a plate material such as plywood to both sides of a heat insulating material has been developed and put into practical use.
If such panels are formed with a certain strength, especially on both sides of the board, it is possible to construct walls, floors, etc. without using the structural members of wooden buildings such as columns and joists, which were required in the past. Can be.

Further, according to the method using such a panel, not only these structural members can be omitted, but also the assembling is easy and large-scale technical skills are almost unnecessary, and the working period can be shortened. There is an advantage that cost can be reduced by production.

FIG. 6 shows such a conventional multifunctional structural panel. This panel 1 has a heat insulating material 2 made of expanded polystyrene as a core material, and plywoods 3 having predetermined strength are joined to both surfaces thereof.

When such panels 1 and 1 are erected and arranged side by side, as shown in FIG. The space is joined.

[0007]

By the way, in such a panel 1, the structural plywoods 3, 3 on both sides and the central heat insulating material 2 are joined by an adhesive such as epoxy resin.

[0008] However, in the case of bonding with such an adhesive, curing for about one day is usually required until a predetermined strength is obtained. Therefore, until then, it could not be installed on the site, of course, it could not be moved, and improvement in quality control was desired.

In view of the above-mentioned circumstances, the present invention can form a multifunctional structural panel without spending a lot of time on curing, thereby improving productivity in integrated production. It is intended to provide a multifunctional structural panel.

[0010]

The structural multifunctional panel according to the present invention for achieving the above object can form a wall of a self-supporting building by arranging its ends on a base with their ends facing each other. And a structural multifunctional panel capable of forming a ceiling or floor capable of bearing a load by itself by arranging its ends on a wall of a building, wherein the core material is formed of a foamed synthetic resin Having a self-adhesive property injected between the core material and the structural plate material, and a structural plate material disposed opposite to both main surfaces of the core material.
Between the core material and the structural plate material.
Are joined by the self-adhesive foam synthetic resin.
It is characterized by having been.

[0011]

According to the above construction, when, for example, urethane foam is used as the self-adhesive foamed synthetic resin, the urethane foam generates heat, but this heat adversely affects the structural plate material such as warpage or deformation. The bonding between the foamed synthetic resin serving as the core material and the structural plate material can be performed in about 30 minutes without imparting heat. Moreover, since the cured urethane foam itself exhibits excellent heat insulating properties, sufficient heat insulating performance can be exhibited as the whole panel.

Therefore, a predetermined strength can be exhibited in a relatively short time, which is convenient for integrated production. In addition, this panel itself becomes a constituent material for walls, floors, roofs, etc., so when used as a wall panel, for example,
Structural members such as pillars and studs are not required, so that large engineering skills can be almost eliminated, and the construction period can be shortened.

Further, a free design is possible by combining the panels.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to 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 core member 11 made of synthetic foamed resin, plate-like substantially rectangular structural plywoods 12 and 13 disposed on both sides of the main surface of the core member 11, and A plurality of spacers 47, 47 (only one side is shown) arranged at predetermined intervals between the core material 11 and the structural plywood 12, 13, and after arranging these spacers 47, the structural plywood 12, 13 and the core And a self-adhesive foam synthetic resin 21, 21 filled in a gap between the material 11.

The core material 11 is made of a molded synthetic foamed resin such as expanded polystyrene, expanded polyurethane, expanded polypropylene and the like. In addition, as another heat insulating material having a predetermined heat insulating performance, for example, the heat insulating material is made of a quasi-incombustible or more material made of a foam mainly containing a vinyl chloride resin containing an inorganic filler or a chlorinated vinyl chloride resin. There is heat insulation. In this case, there is an advantage that not only heat insulation performance but also fire resistance performance and light weight are excellent. Further, as another heat insulating material, for example, a heat insulating material formed of acrylic resin, vinyl chloride, phenol resin, or the like may be used. The point is that any synthetic resin having heat insulation performance may be used, and the material is not limited at all. The expansion ratio is arbitrary, but when polystyrene is used, the expansion ratio is 20.
６０60 times, desirably 30 to 40 times.

The panel 10 has predetermined gaps S formed in the upper and lower portions in a state of being erected in the longitudinal direction. That is, the core material 1
The length of 1 in the longitudinal direction is set shorter than the structural plywoods 12 and 13. In the state where the core material 11 is erected, recesses 14, 1, into which a sub-plate is to be inserted later are formed on the lateral end face.
4 are formed, whereby the end surface of the core material 11 is formed in a convex shape.

The structural plywoods 12 and 13 are made of, for example, a chip board, a wafer board, or wood wool cement. The spacer 47 is preferably made of low-foamed polyurethane or polystyrene. The spacer 47 is attached with an adhesive or the like.

Foamed synthetic resin 21, 21 injected on both sides
Examples thereof include a polyurethane foam and a phenol foam, and a polyurethane foam is preferable. When this polyurethane foam is used, 20 to 20
It cures in about 30 minutes and exhibits an adhesive effect. In addition, there is no fear that the structural plywoods 12 and 13 are warped or deformed due to the heat generation temperature at the time of foaming. The path formed in this way
In the panel 10, the insides of the structural plywoods 12 and 13 are
Core 11, spacer 47 and self made of polystyrene
It is made of a foamed synthetic resin 21 having an adhesive property.
To form a heat insulation layer, so that the entire panel has sufficient heat insulation
Ability can be exhibited.

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

Further, a lower frame 17 is hit on the upper portion of the floor material 16 with a nail or the like. The lower frame 17 is formed of a long object that fits into a gap S provided above and below the panel 10.

On the other hand, as shown in FIG. 3, sub-plates 18 are inserted into the recesses 14 in the panel 10 in advance. After hitting the lower frame 17 on the floor material 16 as described above,
The lower portion of the panel 10 is sandwiched in the lower frame 17 to perform positioning. Thus, one panel 10 is erected on the lower frame 17.

Thereafter, a structural adhesive is applied to the fore-edge surface of this panel 10 and another panel 10 is abutted. At that time, as shown in FIG.
The gap between them is about 1 mm to 5 mm, and a clearance is provided here, but the fore-edge surface is compressed. Thereafter, nails 20 are driven between the two panels 10 and 10 from the outside of the panel 10 at predetermined intervals as shown in FIG.

It is preferable to apply a structural adhesive between the sub-plate 18 and the structural plywoods 12 and 13. In this manner, the panel 10 and the adjacent panel 10 are arranged side by side, and a wall that can bear a load by itself is constructed. An upper frame 19 of a long object is provided on the upper part of the panel 10 similarly to the lower frame 17.
Is handed over. Thus, around the building, the lower frame 1
A wall integrated with the upper frame 19 and the upper frame 19 is constructed.

As described above, when the panel 10 is used standing upright as a wall panel, the compressive force in the vertical direction can be borne by the structural plywoods 12 and 13 on both sides. Therefore, pillars, studs,
The wall can be constructed without using structural members such as braces.

If necessary, a stud material may be inserted into a panel at a corner of a building or a portion subjected to a vertical load. If the panel 10 is used as a wall material as in the present embodiment, a structural member such as a pillar is not required, and when a window or the like is further installed, a cut is formed in a predetermined place of the panel 10 in advance, The window frame may be fitted into this part. This makes it possible to easily process the opening and the like on site.

As described above, according to the panel 10 formed in this embodiment, the molded heat insulating material and the structural plywood are joined to each other by injecting a foam having self-adhesiveness. This eliminates the need for complicated operations such as applying an adhesive to the entire surface.

Further, since the time required for curing can be shortened, transportation and management become easy even in mass production. Also,
Since the inside of the panel is entirely made of heat insulating material,
Good heat insulation can be exhibited. As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example, Various modifications are possible based on the technical idea of this invention.

For example, in the above embodiment, the spacer 47 is interposed to set the interval between the plywoods 12,
This spacer 47 is not always necessary. Further, in the above embodiment, the molded foamed synthetic resin serving as the core material 11 is a continuous molded product. However, as shown in the panel 50 shown in FIG. Lumber 3
The present invention can also be applied to an arrangement in which 5, 36 are arranged side by side.

In this case,. The butted portions of the core members 35 and 36 are formed by using such a self-adhesive foamed synthetic resin 37.
May be joined together. 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.

[0031]

As described above, in the structural multifunctional panel according to the present invention, since the self-adhesive foamed synthetic resin is injected between the structural plate and the core, they are joined. You only have to wait about 30 minutes before curing. Therefore, it is preferable in moving and managing the panel. Therefore, it is easy to perform integrated production.

Also, this panel itself can be used for walls, floors,
