Abstract

PROBLEM TO BE SOLVED: To prevent degradation of the heat insulation of a joined part, and improve the durability by joining two structural surface members by a piece across joints of papels without charging any joining materials inside the panels when the surface materials are sandwiched by interposing only the heat insulation material. SOLUTION: Structural surface materials 11 contain the wooden material such as plywood, oriented strand board, and wooden piece cement, and are formed of the material other than a single plate. A heat insulation material 12 which is a core, is a formed heat insulation material 12, and above all, the foamed body of synthetic resin is suitable, including hard polyurethane foam and phenol foam. A joining piece 2 across joints may be of any type so long as panels can be joined with each other across the joint, and an iron clamp and a staple which are easily available are preferable. Because the panels can be directly joined with each other without charging the joining part material such as spline in the joining part of the panels, degradation of the heat insulation can be prevented, and the heat insulation can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel used for walls, roofs and floors of buildings, and more particularly, to a structure in which two structural surface materials are sandwiched by interposing only a core material made of a heat insulating material. The present invention relates to a panel joining method.

[0002]

2. Description of the Related Art Conventionally, in a case where two structural surface materials are sandwiched only by sandwiching panels each having a core material made of a heat insulating material interposed therebetween, as shown in FIGS. Then, a material (4) for joining, such as hiring fruit, is loaded from the small edge of the panel (3), and the panels are fitted together. And the panel (3) is inserted through the joining material (4).
Were joined together. Wood, oriented strand board, or the like is used as the joining material (4) for hiring and the like.

[0003]

However, in the above-mentioned conventional joining method, despite the use of the panel (3) which is excellent in heat insulation and uses the heat insulating material (32) as the core material,
In order to load a joining material (4) such as a hiring fruit or the like at a joint portion between the panels (3), a place without heat insulating material (32) was provided, and the joining material (4) was loaded therein. Later, since the panels (3) are joined to each other via the joining material (4), the heat insulation performance of the joining portion is significantly reduced,
There is a problem that dew condensation occurs and the durability performance is remarkably deteriorated when the joining portion serves as a thermal bridge.

When the panels (3) are joined together,
It is necessary to previously load a joining material (4) such as a real employment into a fore edge portion of one of the panels (3) to be joined, and a real employment portion (convex portion) provided on one side is connected to the other. The panel (3) had to be moved laterally so as to fit into the recess, which greatly impaired the workability. In addition, it is necessary to make an adjustment beforehand so as not to cause a step difference between the panels (3) after joining, which is disadvantageous in that it takes much time and effort.

In order to join the panel (3),
First, a metal material such as a nail or a staple is driven from the outside of the panel (3) on one side to fix a joining material (4) such as a real person, and then, the outside of the panel (3) on the other side. Since it is necessary to cast metal such as nails and staples and fix it to the joining material (4) such as hiring fruit, a large number of metal such as nails and staples are required, and the time and labor for casting are very large. There is also the disadvantage of this.

Further, there is another problem that the heat insulating material interferes with the bonding material (4), such as a helmet, loaded from the panel edge and generates noise. SUMMARY OF THE INVENTION An object of the present invention is to provide a composite panel joining method which can solve the above-mentioned problems that the conventional composite panel joining method has.

[0007]

According to the joining method of the present invention for solving the above-mentioned problems, two structural surface materials are sandwiched by interposing only a core material made of a heat insulating material. In a method for joining panels, a method for joining composite panels, wherein the panels are not loaded with a joining material such as a fruit or the like, and the panels are joined to each other with a metal straddling a joint between the panels. It is.

Hereinafter, the present invention will be described in detail. The structural surface material referred to in the present invention refers to a material containing a wood-based material such as a plywood, an oriented strand board (hereinafter, referred to as OSB), a particle board, a wafer board, a wood chip cement board, and the like, other than a veneer. In the present invention, among other things, after artificially drying a thin piece of wood, OSB laminated and bonded using a wax and a thermosetting resin, etc., is lightweight,
Bending strength, Young's modulus, and shear strength have properties exceeding that of veneer, and large-size plates with less variation in quality due to nodal holes can be obtained more easily than veneers.
Particularly preferred. Further, the two structural surface materials via only the core material made of a heat insulating material may be of the same type, or the types may be changed one by one.

The heat insulating material referred to in the present invention means a molded heat insulating material, and among them, a synthetic resin foam is preferable. For example, rigid polyurethane foam, polystyrene foam, phenol foam and the like can be mentioned. In the present invention,
Any synthetic resin foam may be used, but in particular, when workability is required in a later step or in practical use, a polystyrene foam that can be easily processed by a hot wire is particularly preferable, and a material that is difficult to burn is required. If so, non-flammable phenolic foams are particularly preferred.

[0010] In the present invention, it is most preferable that the heat insulating material as the core material and the structural surface material are integrally bonded to each other by using the heat insulating material itself as an adhesive because the structure is simple. The heat insulating material and the structural surface material may be bonded and integrated using an adhesive. The hardware that crosses the joint in the present invention may be any metal as long as the panels can be joined to each other across the joint, but clamps and staples, which are easily available, are particularly preferable.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described more specifically by way of examples.

[0012]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of a joining method according to the present invention. FIG. 2 is a cross-sectional view showing the joint of FIG. FIG. 3 is a perspective view showing a conventional joining method. FIG.
FIG. 4 is a cross-sectional view showing a joint of FIG. 3.

As shown in FIG. 1, a panel (1) according to the present invention comprises two structural surface materials (11), each of which is a heat insulating material (1).
It is configured in a sandwich shape with only the core material of 2) interposed. OSB is used for the two structural surface materials (11).
Is used. In addition, polystyrene foam is used for the heat insulating material (12). As shown in FIG. 2, the panels (1) are connected to each other without loading a joining material (4) such as a nut or the like inside the panels (1) as shown in FIG.
They are joined by hardware (2) that straddles the joints. Clamps are used for hardware that straddles the joints between the panels (1).

[0014]

According to the invention of the present application described in detail above, the panels having excellent heat insulating properties with the core material as the heat insulating material are used for the joints between the panels, and the joining material such as fruit is used. Since it is possible to directly join without loading, the heat insulating performance of the joint does not decrease. Therefore, the composite panel joining method according to the present invention has an extremely excellent effect that the durability performance is remarkably improved because dew condensation does not occur.

Further, when the panels are joined to each other, the panels can be simply and easily joined to each other after the joining without having to previously load a joining material such as a real fruit into the fore-edge of one of the panels to be joined. It is possible to join the panels without creating a step. Further, when the panels are joined to each other, since the panels can be uniformly joined with hardware that straddles joints between the panels, there is no need to cast metal from the outside of each of the panels. It becomes possible to reduce to. Furthermore, since there is no need to load a joining material such as a mate that interferes with the heat insulating material in the panel edge, the joining material such as a mate and the heat insulating material may interfere after the panel is joined. This has the effect of eliminating the problem of making noise.
