[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to inner and outer walls of a building such as a house or an agricultural livestock house constructed by a panel construction method,
The present invention relates to a composite panel material for a building structure that constitutes a floor, a ceiling and the like.

2. Description of the Related Art Conventionally, in conventional construction methods such as a frame construction method, a heat insulating material made of a resin foam material such as expanded polystyrene, expanded polyurethane, expanded polypropylene, or a heat insulating material such as gypsum board is used for housing construction. It has been performed to improve airtightness and heat insulation inside a house by using it as an interior material or disposing a heat insulating material inside an exterior material such as a sizing board.

However, in recent years, in order to simplify the steps of housing construction work and reduce the cost, as shown in FIG. 6, a heat insulating material 202 which is a core material made of a resin foam material.
204 made of compressed wood such as plywood on both sides of
The composite panel material 200 in which the above are joined is put to practical use. That is, a so-called panel capable of constructing a wall surface, a floor surface, or the like by providing plate materials on both sides of a panel material with a predetermined strength and without using structural members such as columns, joists, braces, etc., which have been conventionally required. Construction methods are beginning to be adopted.

As an example of such a construction method, a construction method as shown in FIG. 7 is used. That is, in this construction method, the floor material 101 made of a composite panel material is provided on the foundation 100.
Is arranged, the lower frame 102 is fixed on the floor material 101, and a plurality of prepared composite panel materials 103 are connected to each other through a joint (not shown), while being formed at the lower end of the composite panel material 103. In this method, the upper frame 104 is fixedly arranged on the lower frame 102 via a recess (not shown), and the upper frame 104 is inserted into the upper frame recess 105 formed in the upper portion of the composite panel material 103 to construct the composite panel material 103.

By the way, in such a composite panel material, since the resin foam material is used as the core material, it is excellent in heat insulating property, but it is used as a measure of structural strength for use in the panel construction method. In terms of structural strength, the wall magnification strength and bending strength, which have been considered, are still unsatisfactory. Therefore, in the conventional composite panel material, in order to improve the wall magnification strength and the bending strength, it is necessary to increase the thickness of the plate materials on both sides, and as a result, the composite panel material becomes bulky and heavy. Since it becomes heavy, it was inconvenient to handle when it was used in the panel construction method. In addition, since the design of the building is also restricted, the living space becomes small, which is not preferable.

[0006] Further, since the plate material made of wood material of compressed structure such as plywood is joined to both sides of the heat insulating material, the plate material may swell due to rain water, dew condensation, etc., and the strength becomes weak. This is not preferable, and there is a problem that the composite panel material is warped to impair the structural strength, heat insulation, and appearance.

In view of the above situation, the present invention is excellent in heat insulating property and structural strength such as wall magnification strength and bending strength, and its thickness and weight are reduced, which is convenient for handling in panel construction method. The purpose of the present invention is to provide a composite panel material for a building structure, which is not restricted in terms of building design.

It is another object of the present invention to provide a composite panel material for a building structure, which does not swell due to rainwater, dew condensation or the like, and does not impair its structural strength, heat insulating property and appearance.

A composite panel material for a building structure, wherein a lath is integrally bonded to one surface and a structural surface material is attached to the lath bonding surface via an adhesive layer.

As described above, the resin foam layer is used as the core material, and the lath is integrally bonded to the surface of the resin foam layer, and the structural surface material is attached to the lath bonding surface. . Therefore, in addition to utilizing the heat insulating property and light weight of the resin foam, the lath functions as a reinforcing material, and in combination with the mechanical strength of the structural surface material, the wall magnification strength of the entire composite panel material, Mechanical strength such as tensile strength and bending strength is increased, it has self-supporting property that it can bear excessive load by itself, and it is a composite panel material for construction used for panel construction method such as wall and floor material that is also extremely excellent in strength. Can be provided.

Further, as a state in which the lath is integrally joined to the resin foam layer, the lath is integrally or integrally protruded from the surface position of the resin foam layer or in a partially protruded state. If so, mechanical strength such as tensile strength and bending strength is increased. Further, even if the lath is embedded in the vicinity of the surface of the resin foam layer and bonded and integrated so that the outer end position of the lath and the surface position of the resin foam layer coincide (that is, are flush with each other).

INDUSTRIAL APPLICABILITY The composite panel material of the present invention uses a heat-insulating and lightweight foamed resin as a core material for the resin foam layer, and further functions as a reinforcing material on the upper and lower surfaces of the resin foam layer. Since the laths are integrally joined and structural surface materials having excellent mechanical strength are attached to the upper and lower surfaces thereof, the invention is a very excellent invention that exhibits the following remarkable and unique action effects. (1) The properties of these members are exerted in combination, and the lath is reinforced because the laths are integrally bonded to the upper and lower resin foam layers and the structural face material. By functioning as a material, mechanical strength such as wall magnification strength and bending strength of the entire composite panel material is increased.
