Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel, and in particular, a column, a structural plywood body, a heat insulating material, etc., which have been conventionally constructed at the site, are integrally assembled in advance in a production factory,
The present invention relates to an outer wall panel that can improve work efficiency and is excellent in heat insulation effect and countermeasure against dew condensation.

[0002]

2. Description of the Related Art Conventionally, in order to enhance the heat insulating effect of a wall in a wooden house, it has been practiced to put a heat insulating material such as glass wool or foam polystyrene between the exterior material and the interior material. As a ventilation measure in the wall surface, after mounting the structural plywood body or board after the upper building of the frame,
This is done by attaching furring strips and braces to this, and then attaching an exterior material such as a siding board on this to obtain an air layer between the structural plywood body and the exterior material.
In addition, even when the wall is a unit-shaped assembled panel at the factory in advance, it has a similar structure such as providing an air layer by providing a furring strip or a streak in the panel. It is a thing.

[0003]

However, the above-mentioned conventional techniques are problematic in terms of construction period because of the time and effort required for carpentry when the conventional method is used. Also, in the case of a unitized panel, an air layer is made to exist in the panel wall, but this air is stagnant in the panel and it is insufficient as a measure against dew condensation. It was

The present invention has been proposed in view of the above problems of the prior art. In the outer wall panel formed into a unit shape that can shorten the construction period on site, the heat insulating effect is high and the structural It is an object of the present invention to provide an outer wall panel that is panelized into a unit shape that is rich in air permeability without dew condensation, even if the wall thickness is not excessively thick even if it is extremely strong.

[0005]

According to the present invention, there is provided a structural plywood body, a first heat insulating layer member having projections formed on one surface thereof at predetermined intervals, and a second heat insulating layer member having a plurality of through holes. A heat insulating layer member, a third plate-shaped heat insulating layer member, and a panel frame member that holds the first to third heat insulating layer members in a multi-layered manner on the structural plywood body, A ventilation chamber is defined between the structural plywood body and the second heat insulating layer member by a projection formed on the second heat insulating layer member, and the first heat insulating layer member and the third heat insulating layer member are provided. The through-hole portion of the second heat insulation layer member sandwiched by and is formed as an air chamber, and a concave groove that opens at the end of the structural plywood body is formed, and the concave groove forms a groove. It is characterized in that the ventilation chamber and the outside of the panel are in communication with each other.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a trihedral view showing a state in which the wall panel of the present invention is attached to a house.
Is an exploded perspective view, and FIG. 3 is an enlarged plan view.

As shown in FIGS. 1 to 3, the wall panel of the present invention comprises a structural plywood body 1, a first heat insulating layer member 2, a second heat insulating layer member 3, a third heat insulating layer member 4 and Panel frame material 5
Consists of

The structural plywood body 1 used in the present invention is
The thickness dimension is not limited as long as it is flat on both sides and has a standard thickness that is normally used for structural walls. At both end portions (upper and lower end portions in the use state) of one surface of the structural plywood body 1, a plurality of concave grooves 11 opening to the end surface (in the illustrated example, five on each end side) are provided. ) It is formed in parallel. As shown in FIG. 1, the length of the recessed groove 11 is formed so as to communicate with a ventilation chamber 23 defined by the structural plywood body 1 and a first heat insulating layer member 2 described later. . Further, the depth of these concave grooves 11 is determined in consideration of the strength of the structural plywood body 1,
For example, when the thickness of the structural plywood 1 is 12 mm,
A depth of about 3 mm is suitable. In addition, the groove 11 can be formed in the left and right lateral end portions to be used as a lateral wall panel.

The first heat insulating layer member 2 is formed in a plate shape, and a plurality of protrusions 21 are regularly provided on the surface facing the structural plywood body 1. The protrusion 21 may be formed integrally with the first heat insulating layer member 2, and
What was molded separately from the 1st heat insulation layer member 2 may be integrally attached to the 1st heat insulation layer member 2 by adhesion. The shape of the protrusion 21 is not limited, and may be a hemispherical shape, a cylindrical shape, or a rectangular shape. In the present invention, the protrusions 21 are not limited to being regularly positioned, but may be randomly arranged.

The second heat insulating layer member 3 is for forming an air layer between the first heat insulating layer member 2 and the third heat insulating layer member 4, and a plurality of through holes 31 are regularly formed. Has been done. Although the shape of the through hole 31 is circular in the figure, the present invention is not limited to this and may be rectangular. Absent.

The second heat insulating layer member 3 does not need to have heat insulating property itself, and the air layer of the air chamber 31 formed by the second heat insulating layer member 3 serves as a heat insulating layer. To do. Therefore, the second heat insulation layer member 3
May use, for example, a paper honeycomb that does not have a heat insulating effect by itself, and may use a material capable of forming an air layer such as glass wool which is used as a general heat insulating material. . By using such a paper honeycomb shape, a lightweight and robust structure can be obtained.

The second heat insulating layer member 3 is formed in a plate shape. The heat insulating layer members 2, 3 and 4 are held in the panel frame member 5 in an accommodated state and fixed to the structural plywood body 1. Note that these members are fixed to each other with an adhesive.

The wall panel thus constructed is shown in FIG.
As shown in FIG. 5, the pillars P are fixedly held, and then the interior panel 6 is attached to the room side for finishing.

Next, the operation of the wall panel of the present invention will be described. Inside the wall panel of the present invention, the ventilation chamber 2 defined by the structural plywood body 1 and the first heat insulating layer member 2 is provided.
3 is a concave groove 11 formed in the upper and lower ends of the structural plywood body 1.
Since it communicates with the outside air via the, the air permeability inside the wall is good. Further, since the air chamber 31 is formed between the first heat insulating layer member 2 and the third heat insulating layer member 4, two layers of air layers are formed in the wall, and the heat insulating effect is obtained. Will be high. Further, since it is the heat insulating layer member that defines these air layers, there is a further heat insulating effect.

Further, according to the present invention, since the outside air can be taken into the ventilation chamber 23, the ventilation is good and the wall is free from dew condensation.

[0016]

As described above, according to the present invention, in the outer wall panel formed into a unit shape that can shorten the construction period on site, even if the outer wall panel has a high heat insulating effect and is structurally robust. It is possible to provide an outer wall panel that is formed into a unitary panel that is rich in air permeability and does not have condensation, without the wall thickness becoming too thick.
