Description

[Detailed description of the device]

[0001]

[Technical Field of Device]

 The present invention relates to a wall structure that can maintain a wooden house and the like with high airtightness and high heat insulation.

[0002]

[Technical background of the device]

 In many cases, such as wooden structures, heat insulating materials made of foamed resin are often used to improve the airtightness and heat insulating properties inside the buildings.

On the other hand, from the viewpoint of simplifying the construction work of a wooden building, a wall panel in which a plate member, a stud, a heat insulating material and the like are integrated has been developed and put into practical use. By laying a wall panel with such a heat insulating material on the exterior wall of a building, the laying of structural members such as braces, which has been common in the past, can be omitted, and the construction period can be shortened. There is an advantage that the cost can be reduced by the integrated production of.

By the way, when mounting such a wall panel as an outer wall, a plurality of wall panels are prepared and two panels are installed between two columns. At this time, the panel and the panel are arranged such that the studs arranged at their ends are butted against each other, and the other end of each panel is attached to a through column, a tube column or the like.

However, although such a wall structure has an advantage that structural members such as braces can be omitted, it has the following problems. That is, since the studs of the wall panel are generally wood products, it is difficult to bring the studs into close contact with each other. Also, since the studs of the panel contain water, this water tends to be lost from the inside over time. Then, there is a problem that the stud becomes thin and twists, or in some cases, bends occur.

Therefore, even if the panel is assembled in a good condition, a gap may be generated in the abutting portion with the passage of time. For this reason, conventionally, the airtightness at the abutting portion of the wall panel has not been sufficient, which causes deterioration of the heat insulating performance from this portion over time, which in turn impairs the heating and cooling effect in the living space. There was a problem.

[0007]

[The purpose of the device]

 In view of the above situation, the present invention can maintain good airtightness and heat insulation between the wall panels, and can provide high airtightness and heat insulation indoors, and also provide a wall structure with good installation workability. Is intended.

[0008]

[Outline of the device]

 The present invention for achieving the above object provides a plurality of walls including a plate member, an outer heat insulating material attached to at least an outer side of the plate member, and a stud attached to an inner side of the plate member. In a wall structure having panels, the studs of one wall panel and the studs of an adjacent wall panel are abutted against each other, and the other end of the wall panel is supported by a through pillar or a pipe pillar on the building side. The studs of the panels and the studs of the wall panel adjacent to the studs are abutted with an airtight member for hermetically maintaining the space therebetween.

In the wall structure according to the present invention, the plate-like members of the wall panel are not abutted with each other, but are abutted with an airtight member interposed therebetween, so that the plate-shaped members can be kept airtight. Further, even if the water evaporates with the passage of time and the stud becomes thin, the airtight member closes the site, so that the airtight performance does not deteriorate.

Therefore, the airtightness / heat insulating property between the wall panels can be maintained in a good state from the beginning of the installation, and by extension, the indoor can be kept highly airtight / highly heat insulating.

DETAILED DESCRIPTION OF THE INVENTION A wall structure according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a wooden house to which a wall structure according to the present invention is applied. FIG. 2 is an exploded perspective view showing the assembly of the wall panel adopted in the wall structure of the present invention. FIG. 3 is a sectional view of an outer wall to which a wall structure according to an embodiment of the present invention is applied. FIG. 4 is a sectional view of a wall panel used in one embodiment.

In the wall structure according to the present invention, a plurality of rectangular wall panels 1 are prepared and used as wall panels. As shown in FIGS. 2, 3, and 4, the wall panel 1 includes a plate-shaped member 2 that forms a structural member between columns, studs 4 and 4 a attached to the inside of the plate-shaped member 2, and the plates. The outer heat insulating material 3 is located outside the plate-shaped member 2 and the inner heat insulating materials 5 and 5 are located inside the plate-shaped member 2. The one stud 4 is arranged substantially at the center of the plate-shaped member 2, and the other stud 4 a is arranged at the end of the plate-shaped member 2.

As will be described later, the plate-shaped member 2 functions as a structural member that receives a horizontal force between columns (the through column 10 and the tube column 11). This can eliminate the need for bracing. Therefore, this plate-shaped member 2 is, for example, a plywood.

The outer heat insulating material 3 and the inner heat insulating material 5 are heat insulating materials of synthetic foamed resin such as expanded polystyrene and expanded polyurethane, and the expansion ratio thereof is arbitrary, but is, for example, 20 to 60 times. However, a fiber-based heat insulating material such as glass wool may be used. The outer heat insulating material 3 and the inner heat insulating material 5 are previously fixed to the plate member 2 with an adhesive or the like.

The wall panel 1 thus configured is laid as shown in FIGS. 1, 2 and 3. That is, as shown in FIG. 1, a foundation 9 is provided on the foundation 8, and through columns 10 and pipe columns 11 are provided on the foundation 9. A body difference 12 and a girder 13 are bridged over these columns 10 and 11. The studs 4 of the wall panel 1 are fitted into the base 9, the body difference 12, and the girder 13, and the end portions of the plate-like member 2 of the wall panel 1 are butted against each other to bring the studs 4 and 4 into contact with each other. Then, the peripheral portion of the wall panel 1 is fixed to the base 9, the pillars 10, 11, the body difference 12, and the girder 13 with nails or the like. This completes the laying of the wall panel 1. Further, in the present embodiment, as shown in FIG. 3, the vertical furring strips 14 are provided on the outer side and the outer side of the end of the heat insulating panel 1, and the exterior material 15 is laid on the outer side thereof. On the other hand, inside the pillars 10 and 11 and the studs 4 and 4a, an airtight moisture-proof sheet 16 and an interior material 17 are laid.

In this way, when the wall panel 1 is installed between the columns, the inner ventilation layer 12 is formed between the airtight moisture-proof sheet 16 and the inner heat insulating material 5, and the space between the outer heat insulating material 3 and the exterior material 15 is formed. An outer ventilation layer 32 is formed on the outer surface. The inner ventilation layer 12 allows the passage of warm air in the winter, and the outer ventilation layer 32 allows the passage of cold air from the outside in the summer. The inner ventilation layer 12 and the outer ventilation layer 32 on both sides of the heat insulating material 5 are not always essential.

In the present embodiment, as shown in FIGS. 2 and 3, the airtight member 30 is interposed between the abutting portions of the adjacent plate members 2 and 2, that is, the abutting portions of the studs 4a and 4a. ing.

The airtight member 30 has an action of keeping the studs 4a, 4a airtight. When this airtight member 30 is interposed, even if the studs 4a, 4a are not in close contact with each other, a gap is not formed in this portion and the airtightness between the panels can be maintained. Can keep indoors highly airtight and highly insulated.

The airtight member 30 preferably has elasticity, and examples thereof include elastic packing, gaskets, and other sealing materials. The packing and gasket are not particularly limited as long as they have elasticity, but it is more preferable that the sealing material has not only elasticity but also adhesiveness to the studs.

As the elastic sealing material, in addition to the sealing material which is generally used for a joint joint of a building and the like, a sealing tape can be mentioned. The sealing material is not particularly limited, but urethane-based, silicon-based, and polysilicone-based materials can be exemplified. A specific example of the sealing tape is "Banseal" (manufactured by Kanegafuchi Chemical Industry Co., Ltd.), which has a soft vinyl chloride foam consisting of closed cells as a base material and has an adhesive and a release paper on one side.

By interposing the sealing tape having elasticity in this way, even if the stud 4a or the like is thin, it is possible to follow these thinness due to the elasticity of the seal.

Therefore, according to this embodiment, even if there is a gap between the studs 4a and 4a when the panel is installed, or even if a gap is generated in this portion due to the thinness of the studs 4a and 4a later. However, these gaps are not exposed because the airtight member 30 is interposed.

Compared with the case where sufficient airtightness and heat insulating properties could not be obtained between the studs 4a, 4a, the airtight member 30 is provided in this way in the present embodiment, It is possible to obtain sufficient airtightness and heat insulation without deteriorating the airtightness and heat insulation at the abutting points of the panels.

Although one embodiment of the present invention has been described above, the present invention is not limited to the embodiment and various modifications can be made based on the technical idea of the present invention. For example, in the above embodiments, the outer heat insulating material 3 is provided on the outer side of the plate-shaped member 2 and the inner heat insulating material 5 is provided on the inner side thereof. However, like the wall panel 40 shown in FIG. 5 and FIG. For example, only the outer heat insulating material 3 may be used as the material, and the inner heat insulating material may be omitted.

Further, although not particularly described in the above embodiments, the airtight member 30 may be interposed also in the connection between the wall panel 1 and the pillar 10 and the tube pillar 11.

[0026]

[Effect of device]

 As described above, in the present invention, the airtight member is provided at the abutting portion of the studs of the wall panel and the studs adjacent to the studs. Therefore, the airtightness / heat insulating property does not deteriorate at the abutting portion of these studs, and sufficient airtightness / heat insulating property can be obtained.
