Abstract

PROBLEM TO BE SOLVED: To attain high heat insulation performance by fitting a heat insulating material with its peripheral edge part left on both the surfaces of a plate material of plywood or the like, forming one heat insulation material out of closely bonded and layered hard foaming resin, and the other heat insulation material out of partially jointed hard foaming resin. SOLUTION: An heat insulation panel 5 is provided with an outside heat insulation layer 7 formed by bonding and layering hard urethane foam closely on the surface of a plate material 6 of plywood or the like, and an inside heat insulation layer 8 formed by partially-bonding styrene foam to the back surface of the plate material 6. The heat insulation layer 7 is formed by bonding and layering the hard urethane foam closely on the surface of the plate material 6, and the inside heat insulation layer 8 is formed by partially-bonding glass wool to the back surface of the plate material 6 to form the heat insulation panel 5. The heat insulation panel 5 is fitted between a column, a stud, and a horizontal member, and the collar part of the plate material 6 is nailed at the side surface of the column. Therefore, by giving the rigidity of the plate material to improve earthquake-proofing as the structural material of a face bar proof stress wall, it is possible to attain excellent heat insulation performance.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a heat-insulating panel used for a roof and a floor, particularly a wall of a building such as a house.

[0002]

2. Description of the Related Art Conventionally, a heat insulating panel in which a plate material such as plywood and a foamed plastic heat insulating material are integrated has been used for roofs, walls, floors and the like of buildings. These heat insulation panels are obtained by joining a wooden frame to one side of a plate material, and spraying or injecting resin as a raw material of foamed plastic into a space surrounded by the surface material and the frame material, or by laminating one side of the plate material. In rare cases, a separately molded foamed plastic board was attached to both sides with an adhesive.

[0003]

However, in the case where a wooden frame is joined to one surface of a plate material and a heat insulating material is laminated in a space surrounded by the surface material and the frame material, only one surface is provided. Therefore, the thickness of the heat insulating material is limited, and the frame material becomes a thermal bridge, and it is difficult to secure sufficient heat insulating performance. Further, the weight increases due to the presence of the frame material, and the workability is poor.

[0004] When a foamed plastic board separately molded on a plate material is bonded with an adhesive, it takes two steps of a board forming step and a bonding step, and a large amount of adhesive is required to increase the bonding area. However, there is a problem that the production cost is increased due to the use of.

[0005] The problem to be solved by the present invention is to provide an inexpensive product that prevents thermal bridges, secures a sufficient thickness of the heat insulating material to provide a panel having high heat insulating performance, and is not troublesome to construct. What measures should be taken to achieve this?

[0006]

In order to solve such a problem, according to the present invention, a heat insulating material is attached to both sides of a plate material such as plywood while leaving a peripheral portion, and one of the heat insulating materials is attached to the surface of the plate material. The present invention proposes a structure of a heat insulating panel in which a rigid foamed plastic heat insulating material closely adhered and laminated is used, and the other heat insulating material is a hard foamed plastic heat insulating material partially bonded to the back surface of the plate material or a fiber heat insulating material.

[0007]

The structure described above has the following effects. (1) Since the heat insulating material on one side is a hard foamed plastic heat insulating material closely adhered and laminated on the surface of the plate material, the rigidity of the plate material is increased. This means that out-of-plane buckling is unlikely to occur even when the plate is subjected to a large shear load. become. (2) The heat insulating material on the other side is partially bonded to the surface of the plate material by bonding or the like. Usually, with this side facing the interior side of the outer wall, the partially bonded heat insulating material is used as a pillar / stud.・ The flange of the plate is nailed to the side of these frames so as to fit between the horizontal members, but if the notch of the heat insulator is required according to the frame, the plate and the heat Notch work is easy because of partial joining. In addition, when a fiber-based heat insulating material is used instead of the partially joined hard foamed plastic heat-insulating material, the fiber-based heat insulating material has elasticity and shape-following properties. , Fits without gap between the frames. (3) Because there is no frame material surrounding the insulation,
Since no thermal bridge occurs, the heat insulation performance is improved.

[0012]

Since the present invention is constructed as described above, it has the following effects.

(1) Since the heat insulating material on one side is a hard foamed plastic heat insulating material closely adhered and laminated on the surface of the plate material, the rigidity of the plate material is imparted and the earthquake resistance as a structural material of the surface material bearing wall is enhanced. . (2) Since the heat insulating material on the other surface is partially joined to the surface of the plate material, when the heat insulating material needs to be cut in accordance with the frame, the notch work is easy. (3) When the fiber-based heat insulating material is used for the inner heat insulating material, the fiber heat insulating material can be fitted without any gap between the frames without requiring a cutout or the like. (4) Since there is no frame material surrounding the periphery of the heat insulating material, no thermal bridge occurs and the heat insulating performance is high.
