Abstract

PROBLEM TO BE SOLVED: To provide excellent heat insulating property in a bearing panel mounted between struts of a wooden building by successively connecting and integrating an interior plate, a hard foamed urethane resin layer, and a metal plate to form the bearing panel. SOLUTION: A hard foamed urethane resin layer 2 and a metal plate 3 are successively bonded and integrated to an interior plate 1 consisting of a wood or plaster board, cement board or the like to form a bearing panel A. A synthetic resin frame member 15 having a T-shaped recessed part is provided in the thickness directional center along the circumferential part of the bearing panel A. One end of T-shape of a T-shaped sheet metal mounting member 16 is fitted to the recessed part 15 of the frame member 15, and the flat other end thereof is butted to a strut 10 and fixed by a nail 11 to mount the bearing panel A between struts 10. Accordingly, excellent heat insulating property and airtightness can be provided, and the handling operability and constructing property can be enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a load-bearing panel for a wooden building, and more particularly to a load-bearing panel excellent in heat insulation, installation workability and strength.

[0002]

2. Description of the Related Art Conventionally, as a wall material between columns in a wooden building, as shown in FIG. 6, a hard urethane foam resin layer 22 is integrally bonded to the back side of a plywood 21 or a glass wool is used as a heat insulating layer. True wall panels are widely used. In this type of panel for a true wall, a wooden frame 23 for attaching to a support is usually attached to an edge portion of the plywood 21, and a nail is driven into the support from the inside of the frame 23 to insert the support between the supports. The attachment is fixed.

[0003]

However, the heat insulation of wood is, for example, 1/10 that of hard foamed urethane resin.
Since there is only the following, the heat insulating property of the above-described conventional true wall panel is reduced at these wooden frames 23.
Further, when the braces are inserted between the columns, the depth between the columns is reduced by the thickness of the braces, so that the conventional panel cannot be attached, and the heat insulation of the portion is greatly reduced.

[0004] In recent years, it has been said that installing a load-bearing panel rather than inserting braces between columns increases seismic strength.
Therefore, instead of the conventional panel, a bearing panel in which a rigid urethane foam resin layer is bonded and integrated between two metal plate bodies is also known, but processing of a metal surface on the indoor side, for example, plaster or Not only is it not easy to apply painted walls, etc.
Normally, in order to suppress the bending deformation and increase the plate strength, the metal plate is thickened, or the surface or the back surface of the metal plate, or the metal plate itself is provided with small rib-like irregularities, so interior decoration processing is difficult However, the application to houses will be even more difficult. Furthermore, since both sides are formed of metal plates, the panels themselves are inevitably heavy, and the operability and workability are reduced, which is not practical. There is a drawback that liable to occur.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a load-bearing panel for a wooden building which is excellent in heat insulation and strength, lightweight, and particularly excellent in handling and workability such as mounting, and workability. .

[0006]

SUMMARY OF THE INVENTION In view of the actual situation of the above-described load-bearing panels, the present inventors have paid particular attention to heat insulation, structural strength, and handling workability. The panels of the present invention were completed by stacking. In the load-bearing panel of the wooden building of the present invention, the interior plate, the hard urethane foam resin layer and the metal plate are sequentially joined and integrated.
The term “interior board” as used herein includes, in addition to softwood interior boards and hardwood interior boards, inorganic interior boards [eg, Dailight, Daiken Kogyo Co., Ltd.]
Trade name] or similar interior boards, gypsum boards, and cement boards. The interior board has a specified thickness of 7 mm
Using the above, a rigid urethane foam resin layer and a metal plate are sequentially joined and integrated with an adhesive to form a load-bearing panel of the present invention.

[0007] The rigid urethane foam resin layer is formed to a thickness of 40 to 70 mm depending on the region where the load-bearing panel of the present invention is used, and the metal plate is formed to a thickness of 0.4 to 1.0 mm.
May be formed in a flat plate shape, or may be formed in a wavy shape or a square wave shape in order to enhance strength.

The above-mentioned load-bearing panel of the present invention is mounted and fixed between columns. As a mounting means, a frame material made of synthetic resin having a concave portion on the peripheral side of the load-bearing panel is provided. It is preferable to use a mounting member that can fit one end into the recessed part of the above and the other end can be mounted on the column. The frame material is a long body made of a synthetic resin such as a vinyl chloride resin, and is provided in a recessed portion on a peripheral side portion of the load-bearing panel.

In another aspect of the load-bearing panel of the present invention, an interior board, a hard urethane foam resin layer, and a metal plate are sequentially joined and integrated, and a peripheral portion of the metal plate is extended over the entire edge. It may be formed in the shape of an overhanging plate bent at a right angle to the other side. The peripheral portion of the metal plate serves as a frame for attaching and fixing the load-bearing panel of the present invention between the columns, and is fitted with an edge portion of a metal side plate described later, and the column is formed from the peripheral portion side. A fastener such as a nail is driven into the support via a metal side plate that is in contact with the side surface. The overhang length of the peripheral portion is preferably 40 to 75 mm.

[0010] The side surface of the load-bearing panel is covered with a stainless steel plate or a metal side plate subjected to rustproofing. To attach the metal side plate to the load-bearing panel, a synthetic resin grooved rod is attached to the edge of the hard urethane foam resin layer on the interior plate side, and one opening end of the metal side plate is attached to the opening. This is performed by inserting the entire edge of the portion and fitting the other edge to the edge of the metal plate. As this fitting form, it is preferable to bend the edge portion of the metal side plate over the entire edge and to sandwich the edge portion of the metal plate inside the bent portion.

The above-mentioned channel-shaped rod is a long body made of a synthetic resin such as a vinyl chloride resin, and an edge of one bent end of a metal side plate is inserted into an opening of the rod. With this configuration, it is possible to prevent the metal side plate from directly contacting the interior plate, thereby preventing the occurrence of dew condensation at this portion. In the load-bearing panel of the present invention, pieces are preferably provided at intervals between the interior plate and the metal plate in order to prevent the center portion of the load-bearing panel from being crushed by an external load.
