Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building panel used for a wooden house.

[0002]

2. Description of the Related Art Conventionally, architectural panels of this type have been arranged in a space formed by an interior material and an exterior material for the purpose of improving heat insulation. This wall panel is configured by attaching a heat insulating material and a reinforcing material to a wooden plate. The reinforcing material is made of, for example, wood such as bay pine and hemlock.

[0003]

However, in the conventional building panel, the wood as the reinforcing material shrinks as it dries because it contains a large amount of water at the time of cutting.
Therefore, if the wood is not sufficiently dried, there is a problem that the reinforcing material is warped or twisted, the building panel is deformed, and the workability, durability and heat insulation are reduced.

[0004] The present invention has been made in view of the above problems, and an object of the present invention is to provide a building panel in which workability, durability, and heat insulating properties do not decrease over a long period of time.

[0005]

In order to solve the above problems, according to the first aspect of the present invention, a building in which a heat insulating material and a reinforcing material are provided on a plate-like body, which is arranged between frames of a wooden house. In the panel for use, the gist is that the reinforcing material is made of a laminated material.

According to a second aspect of the present invention, in the building panel according to the first aspect, the laminated material has a gist that a plurality of laminated plate members are bonded to each other. According to the third aspect of the present invention, in the building panel according to the second aspect, the laminated material has a rectangular cross section, and the respective plate members are laminated along a direction parallel to the plate member. The gist is that it has been done.

Hereinafter, the "action" of the present invention will be described. According to the first to third aspects of the present invention, since the reinforcing material is made of a laminated material, the reinforcing material does not expand or contract due to drying with time. For this reason, since the reinforcing material does not warp or twist, the panel is less likely to be deformed. Therefore, there is no decrease in the proof stress or the work cannot be performed. When the panels are arranged side by side, no gap is formed between the panels.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a front view of a wall panel 11 as a building panel viewed from the indoor side of a wooden house. FIG. 2 shows a plan sectional view of the wall panel 11.
FIG. 10 shows a rear view of the wall panel 11 viewed from the outdoor side of the wooden house. As shown in FIG. 1 and FIG.
Is provided with a plate-like body 12 constituting the outer surface thereof, and this plate-like body 12 is formed of a medium fiberboard (MDF: medium density).
fiberboard). This medium fiber board is obtained by hardening crushed vegetable fiber (hemp fiber, bamboo fiber, coconut fiber, or the like).

As shown in FIG. 10, the plate 12 is provided on a frame 13 of a wooden house. Both upper and lower edges of the plate-shaped body 12 are fixed to a horizontal member 15 such as a beam or a base which constitutes the frame 13. The left and right edges of the plate 12 are fixed to the pillar 14. A nailing marking 16 is written on the outdoor side surface S11 of the plate-like body 12 along the periphery thereof. This marking 16 for nailing
It is composed of a plurality of points 16a. Each point 16a has a circular shape with a diameter of about 5 mm, and is all printed. Each point 16a is equally spaced on the same straight line (about 8 in this embodiment).
0-100 mm).

As shown in FIGS. 1 and 2, one stud 17 as a wooden reinforcing member extending along the longitudinal direction of the panel is joined to the center of the indoor side surface S12 of the plate-like body 12. As shown in FIG. 3 (c), the stud 17 is made of a laminated material having a rectangular cross section. The glued laminated material is formed by bonding a plurality of thin plates (plate materials) 18 which are overlapped with each other with an adhesive. In the present embodiment, ten thin plates 18 are used, and each thin plate 18 has a thickness of 3 mm. Each of the thin plates 18 corresponds to the plate 1
The layers are stacked along a direction parallel to 2. The reason why the plate-like body 12 is MDF is that the plate-like body 12 can be mass-produced economically. Further, the strength per unit weight (specific strength) of the plate-like body 12 is about three times that of reinforced concrete, and it is excellent in fire resistance and has semi-permanent durability. Further, there is almost no expansion or contraction or dimensional deviation.

A heat insulating material 20 having an outer diameter slightly smaller than that of the plate-shaped body 12 is provided on the side surface of the stud 17 on the indoor side surface S12 of the plate-shaped body 12. The heat insulating material 20
In other words, it is partitioned by one stud 17. Insulation material 2
0 plays a main part when the wall panel 11 exhibits a heat insulating effect. The heat insulating material 20 is fitted in the installation space K formed in the frame 13. When the wall panel 11 is simply fitted into the installation space K, the indoor side surface S2 of the heat insulating material 20 is arranged at the same level as the columns 14 and the horizontal members 15.

As the material of the heat insulating material 20, foamable polystyrene is used. The reason for choosing polystyrene is as follows. This is because polystyrene has fine and independent pores (discontinuous pores) inside and causes moderate plastic deformation when pressed.

The polystyrene, which is a raw material of the heat insulating material 20, contains a flame retardant. In this embodiment, aluminum hydroxide or a halogen compound is used as the flame retardant. This is to enhance the adhesiveness between the plate-shaped body 12 and the heat insulating material 20. Specific examples of the halogen-based compound include dibromopropyl phosphate, ethane tetrabromide, and bromochloropropyl phosphate. Incidentally, an acrylic resin-based adhesive is used as the adhesive.
The amount of flame retardant is 2% to 30% by weight of polystyrene.
It has become. The amount of flame retardant is 5% of polystyrene.
More preferably, the content is from 10% by weight to 10% by weight.

Further, the expansion ratio of the heat insulating material 20 is 30 to 7
It is set to 0 times. The reason for setting the magnification in this range is as follows. That is, if the expansion ratio is lower than 30 times,
Since the number of bubbles contained in the heat insulating material 20 is reduced, a large amount of polystyrene as a material is required. Therefore, the material cost of the heat insulating material 20 increases. On the other hand, if the expansion ratio is higher than 70 times, the thermal conductivity increases, the heat insulating property decreases, and the strength of the entire heat insulating material 20 decreases. In addition,
The expansion ratio of the heat insulating material 20 is more preferably 35 to 65 times.

As shown in FIG. 1, FIG. 4 and FIG. 6, each heat insulating material 20 has two upper component parts 21a and 21b and two lower component parts 22a and 22b which are divided into upper and lower parts.
