[0002]

2. Description of the Related Art A wall panel of this kind is disposed in a space defined by an interior material and an exterior material for the purpose of improving heat insulation. The wall panel is composed of a wooden plate, a heat insulating material provided on one side thereof, and a stud as a reinforcing material. The studs are attached to the plate by driving nails. When mounting the wall panel, a heat insulating material is fitted into an installation space surrounded by columns constituting the frame and horizontal members such as beams and bases. Here, the internal dimensions between the opposing horizontal members differ from house to house. for that reason,
The lengths of the heat insulating material and the studs in the vertical direction are adjusted at the construction site according to the inner dimensions. Specifically, a part of the heat insulating material and the studs are cut out using a cutting tool such as a saw.

[0003]

However, in the conventional wall panel, since the stud is nailed from the upper end to the lower end, a cutting tool such as a saw may hit the nail when cutting the stud. Therefore, there was a problem that it was difficult to cut the studs according to the dimensions. Also, if you try to forcibly cut with the cutting tool hitting the nail,
It also causes the blade to be damaged.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a wall panel capable of preventing a cutting tool such as a saw from hitting a nail when cutting a reinforcing material.

[0005]

According to the first aspect of the present invention, a heat insulating material and a reinforcing material are provided on one surface of a plate fixed to a frame of a wooden house. The gist of the invention is that a non-nail area where the nail is not nailed is provided in a part of the reinforcing material in a wall panel in which the reinforcing material is attached to the plate-like body by nailing.

According to a second aspect of the present invention, in the wall panel according to the first aspect, the non-pegged region is arranged at an end of the reinforcing member.
In the invention according to Claim 3, in the wall panel according to Claim 1 or 2, one surface of the heat insulating material is adhered to the plate-like body in a state where a non-adhesion region is provided at an edge thereof. The gist is that the non-nail area is arranged at a position corresponding to the non-adhesion area.

Hereinafter, the "action" of the present invention will be described. According to the first and second aspects of the present invention, the reinforcing material is cut out to adjust the length of the wall panel. At the time of this cutting, since a non-pegged area is provided in a part of the reinforcing material, it is possible to reliably prevent a cutting tool such as a saw from hitting.

According to the third aspect of the present invention, the non-pegged area is disposed at a position corresponding to the non-bonded area of the heat insulating material. Therefore, both the heat insulating material and the stud can be easily cut off. Therefore, the length of the wall panel can be adjusted more easily.

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 viewed from the indoor side of a wooden house. FIG.
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 FIGS. 1 and 2, the wall panel 11 includes a plate-shaped body 12 constituting an outer surface thereof, and the plate-shaped body 12 is formed of a medium density fiberboard (MDF). Have been. This medium fiber board is obtained by hardening crushed vegetable fiber (hemp fiber, bamboo fiber, coconut fiber, or the like).

[0010] 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.

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, 2, and 10, one wooden stud (reinforcing material) 17 extending in the longitudinal direction of the panel is provided at the center of the indoor side surface S12 of the plate-like body 12. ing. The stud 17 is provided on the outdoor side surface S11 of the plate-shaped body 12.
It is attached by a plurality of nails 19 hammered from. The nails 19 are struck at predetermined intervals along the longitudinal direction except for the upper end of the stud 17. That is, there is an area where the nail 19 is not driven in a part of the stud 17. Therefore, in the present embodiment, the upper end of the stud 17 is a non-nail driving region T1, and the stud 1
The portion excluding the upper end of 7 is a nailing area T2.
Specifically, a range of 15 cm downward from the upper end surface of the stud 17 is a non-nail area T1. Further, as shown in FIG. 3C, the stud 17 is a laminated material having a rectangular cross section. The glued laminated wood is composed of a plurality of plate materials 1
8 are bonded together with an adhesive.

As shown in FIGS. 1 and 2, a heat insulating material 20 whose outer diameter is slightly smaller than that of the plate-shaped body 12 is provided on the side of the stud 17 on the indoor side surface S12 of the plate-shaped body 12. I have. The heat insulating material 20 is partitioned by one stud 17 so to speak. The heat insulating material 20 plays a main part when the wall panel 11 exhibits a heat insulating effect. The heat insulating material 20 is provided in the installation space K formed in the frame 13.
To be fitted. In a state where the wall panel 11 is simply fitted into the installation space K, the indoor side surface S2 of the heat insulating material 20 is disposed closer to the indoor side than the pillar 14 and the horizontal member 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 the 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.

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.
