Description

Detailed Description of the Invention

[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, which constitutes a floor, a ceiling and the like.

[0002]

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. 11, a heat insulating material 20 which is a core material made of a resin foam material.
A plate material 20 made of compressed wood material such as plywood on both sides of 2
The composite panel material 200 in which 4 is 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. 12 is used. That is, in this construction method, the floor material 10 made of a composite panel material is provided on the foundation 100.
1 is arranged, the lower frame 102 is fixed on the floor material 101, and a plurality of prepared composite panel materials 103 are formed at the lower end of the composite panel material 103 while being bonded to each other via a joint part not shown. Lower frame 102 through a coupling recess (not shown)
This is a method in which the upper frame 104 is fixedly arranged on the upper side, and the upper frame 104 is inserted into the upper frame recess 105 formed in the upper part of the composite panel material 103 to construct the composite panel member 103.

[0005]

By the way, in such a composite panel material in which a board made of a compressive structural wood material such as plywood is joined to both sides of a heat insulating material made of a resin foam material, the board material is damaged by a termite. However, sometimes the resin foam material, which is the core material, may be eaten away, which may impair the structural strength, the heat insulating property, and the appearance, which is a problem.

That is, as shown in FIG. 13, the termites are said to eat up the plate materials 304 on both sides of the composite panel material 302 up to a height S of about 1 to 1.5 m above the foundation 300. . In particular, on the outer wall side, since the termites prefer to eat and roughen the plate material 304 swollen by rainwater, dew condensation, etc., the strength of the portion supporting the load of the composite panel material 302 becomes weak, and the structure of the building as a whole is reduced. The strength is reduced, which is not preferable.

Further, in such a composite panel material, since a resin foam material is used as the core material, it has excellent heat insulating properties, but when used in the panel construction method, the wall magnification strength, which is a standard of structural strength, In terms of bending strength, structural strength was 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.

In view of the above situation, the present invention prevents the panel material from being corroded by termites, has a structural strength,
It is an object of the present invention to provide a composite panel material for a building structure, which does not impair heat insulation and appearance.

In addition to being excellent in heat insulation and structural strength such as wall magnification strength and bending strength, its thickness and weight are reduced, which is convenient for handling in the panel construction method and is not restricted in terms of architectural design. It is also an object to provide a composite panel material for a building structure that does not have any components.

[0010]

The present invention has been made in order to achieve the problems and objects in the prior art as described above, and the composite panel material for building structure of the present invention is an inorganic curable material. An inorganic plate made of a material and a wood plate are fixed on at least one surface of a resin foam plate, an inorganic plate made of an inorganic curable material is attached to the lower part, and a wood plate is placed on the upper part thereof. And

Further, the composite panel material for building structure of the present invention is characterized in that the inorganic plate is fixed so as to have a width of 1 m or more from the lower end of the resin foam plate. Thus, in the composite panel material for a building structure of the present invention, the inorganic plate is fixed below the surface of the resin foam plate so as to have a width of 1 m or more from the lower end of the resin foam plate. By using the panel construction method so that the fixed side becomes the base side, it does not swell due to rainwater, dew condensation, etc. so that it does not warp or corrode, and it is not corroded by termites, so its structure The strength, heat insulation, and appearance are not impaired. In particular, in a composite panel material for building structure having a structure in which an inorganic plate is adhered to both sides of a resin foam plate, such a swelling prevention effect and a termite prevention effect are further enhanced.

Further, the outer end position of the lath and the surface position of the resin foam plate are the same (that is, flush with each other).
As described above, the lath may be embedded in the vicinity of the surface of the resin foam plate to be joined and integrated. In this case, the mechanical strength is further increased and the inorganic plate is directly fixed to the surface by an adhesive ( It can be attached).

The method of joining and integrating the lath to the resin foam plate is as follows: a heated lath is pressed against the surface of the resin foam prepared in advance to weld it, or a resin is foamed in a mold. The method of arranging the lath in the mold can be adopted.

As the inorganic board, an inorganic hardenable material such as gypsum, slate, mortar, lightweight concrete, cellular gypsum, cellular mortar, cellular lightweight concrete may be used. In this case, when the inorganic plate is fixed to the surface of the resin foam plate or the lath-bonding surface thereof using an adhesive, an inorganic molded plate made of these inorganic curable materials may be used. In order to fix the inorganic plate to the surface of the or the lath bonding surface, without using an adhesive, these inorganic curable materials are sprayed, coated, or cast, and then cured to be bonded and integrated.
