DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel, and more particularly, to previously assembling members such as pillars, structural plywood bodies, and heat insulating materials which have been conventionally constructed at a site, in a production factory.
The present invention relates to an outer wall panel capable of improving work efficiency and having an excellent heat insulating effect and a 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, a heat insulating material such as glass wool or foam polystyrene has been put between an exterior material and an interior material. As a measure against ventilation in the wall, after mounting the structural plywood body or board after the upper wing of the frame,
It is performed by attaching a rim or a streak to this, and attaching an exterior material such as a siding board thereon to obtain an air layer between the structural plywood body and the exterior material.
In addition, even when the wall is formed into a unit-like assembled panel in a factory in advance, the panel has a similar structure such as providing an air layer by providing a rim or a streak in the panel. Things.

[0003]

However, the prior art as described above requires a large amount of time and labor for carpenters when using the conventional method, and is problematic in terms of the construction period. Also, in the case of a unitized panel, an air layer is present in the panel wall, but this air is stagnant in the panel, which is insufficient for dew condensation countermeasures. Was.

The present invention has been proposed in view of the above-mentioned problems of the prior art. In an outer wall panel formed into a unit shape which can shorten the construction period on site, a heat insulating effect is high, and furthermore, the structure is improved. It is an object of the present invention to provide an outer wall panel which is formed into a unit-like panel which is highly rugged, does not become too thick, and has no air condensation and has high air permeability.

[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 at predetermined intervals, and a plurality of through holes. A second heat-insulating layer member, a third plate-like heat-insulating layer member, and a panel frame member for holding the first to third heat-insulating layer members in a multilayer shape on a structural plywood body; A ventilation chamber is defined between the plywood body and the first heat-insulating layer member by a projection formed on the first heat-insulating layer member, and is formed by the first heat-insulating layer member and the third heat-insulating layer member. The through hole portion of the sandwiched second heat insulating layer member is formed as an air chamber, and the air chamber is in communication with the outside air at the ends of at least one of the four sides of the structural plywood body. It is characterized by the following.

[0006]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a three side 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 sectional 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, Panel frame material 5
Consists of

The structural plywood body 1 used in the present invention comprises:
The thickness dimension is not limited as long as both surfaces are flush with each other and have a standard thickness generally used for structural walls. At both ends (upper and lower ends in the use state) of one surface of the structural plywood main body 1, a plurality of concave grooves 11 opening to the end surface (in the example shown, five at each end side). ) It is formed in parallel. As can be seen from FIG. 1, the length of the concave 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. . The depth of these grooves 11 is determined in consideration of the strength of the structural plywood main body 1,
For example, when the thickness of the structural plywood 1 is 12 mm,
It is appropriate that the depth is about 3 mm. In addition, the concave groove 11 is not limited to the upper and lower ends, but may be formed at the left and right lateral ends to enable use as a horizontal wall panel.

The first heat insulating layer member 2 is formed in a plate shape, and a plurality of projections 21 are provided on a surface facing the structural plywood main body 1. The protrusion 21 may be formed integrally with the first heat-insulating layer member 2, or may be formed separately from the first heat-insulating layer member 2 by bonding to the first heat-insulating layer member 2. It may be attached to. The shape of the projection 21 is not limited, and may be hemispherical, cylindrical, or even rectangular. In the present invention, the protrusions 21 are not limited to those regularly arranged, 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 has a plurality of through holes 31 formed therein. Is formed. In the drawings, the shape of the through hole 31 is circular, but the present invention is not limited to this, and it goes without saying that the shape may be rectangular. Absent.

The second heat-insulating layer member 3 does not need to have heat-insulating properties itself. The air layer of the air chamber 31 formed by the second heat-insulating layer member 3 is used as a heat-insulating layer. Is what you do. Therefore, the second heat insulating layer member 3
For example, a paper honeycomb that does not have a heat insulating effect itself may be used, and further, a material that can form an air layer inside such as glass wool used as a general heat insulating material may be used. Is also good.

The second heat insulating layer member 3 is formed in a plate shape. These heat insulating layer members 2, 3, and 4 are held in a state of being housed inside the panel frame member 5 and are fixed on the structural plywood main body 1. These members are fixed to each other by an adhesive.

The wall panel thus constructed is shown in FIG.
As shown in the figure, the interior panel 6 is fixedly held between the columns P, and thereafter, the interior panel 6 is attached to the room side to finish.

Next, the operation of the wall panel of the present invention will be described. Inside the wall panel of the present invention, the ventilation layer 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 at the upper and lower ends of the structural plywood body 1
Because it communicates with the outside air through the inside, 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 air layers are formed in the wall, and the heat insulating effect is obtained. Will be higher. In addition, since these air layers are defined by the heat insulating layer members, there is a further heat insulating effect.

Further, according to the present invention, since the outside air can be taken into the ventilation layer 23, the ventilation is good, and no condensation occurs on the wall.

[0016]

As described above, according to the present invention, a plurality of heat-insulating layers are formed, and a part of the heat-insulating layer is formed between the air-permeable layer of the ventilation chamber which communicates with the outside air by the concave groove, and the inner side. The housing has an air layer provided in the housing, and the members that define the ventilation chamber and the air chamber are constituted by heat insulating layer members. Can be obtained. In addition, the presence of the ventilation layer in the ventilation chamber allows the ventilation to be sufficient, and a comfortable living environment can be obtained without dew condensation.
