Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small wall panel used when a window or an opening serving as a doorway is provided on a wall of a prefabricated house or the like.

[0002]

2. Description of the Related Art Generally, in prefabricated houses and the like, labor and simplification of on-site construction work is achieved by standardizing the body, exterior and interior members. And in recent years, a construction method has been adopted in which panels used to form an interior base in advance at a factory are used, and at the site, a frame, for example, a wall or a partition is formed by simply butting and joining these panels. There is.

In such a prefabricated house or the like, when a window or an opening serving as a doorway is formed in a wall or partition, a method of using a small wall panel which is a small wall is used. FIG. 4 shows an example in which an opening serving as a doorway is formed in a part of the partition, and the small wall panel 1 is attached to the upper part of the opening. The small wall panel 1 is attached to the upper end portion between the side end surfaces of the wall panels 2 and 2 which serve as a partition, and is above the opening stands 3 and 3 connected to the respective side end surfaces of the wall panels 2 and 2. It is placed and fixed on. With this structure, the opening 4 serving as a doorway is formed in the lower portion of the small wall panel 1.

Here, in the small wall panel 1, the vertical core members 5 and 5 and the horizontal core members 6 and 6 are assembled in a rectangular frame shape, and the face members 7 and 7 made of plywood are attached to the front and back surfaces thereof. It has been configured.

[0005]

However, in the above small wall panel, when a shearing force parallel to the face material is applied from the lateral direction due to an earthquake or the like, the end portion which is a joint portion with the wall panel is particularly formed. There is a risk that the face will be cracked or the like at the end due to the load being applied to the part.

Further, in the small wall panel, when an inorganic face material is used as the face material instead of plywood, the bonding with the core material is mainly performed by adhesion, so that the bonding strength of the inorganic face material is long-term. There is some difficulty in securing it.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a small wall panel having a sufficient proof strength particularly against a shearing force and a joining proof strength of an inorganic surface material. It is also to provide excellent small wall panels.

[0008]

In the small wall panel of the present invention, upper and lower horizontal core members, vertical core members respectively provided between the end portions of these horizontal core members, and center sides of these vertical core members. And a reinforcing core member provided between the horizontal core members so that the surface of the horizontal core member at the location corresponding to the portion from the vertical core member to the reinforcing core member on the front and back surfaces of the horizontal core member and A notched surface is formed on the entire back surface of each of the surfaces, and the vertical core member and the reinforcing core member are arranged such that the front and back surfaces thereof are flush with the notched surface, and the notched surface, the vertical core member, and the reinforcing core member. A reinforcing surface material is attached to a section formed by the front and back surfaces of the material so as to be flush with the front surface or the back surface of the horizontal core material, and further on the reinforcing surface material and the surface of the horizontal core material, and the reinforcement. The means for solving the above-mentioned problems is that the face material is adhered to each of the face material and the back surface of the horizontal core material.

[0009]

According to the small wall panel of the present invention, the reinforcing face members are provided at both left and right inner sides of the front and back face members, and the face member and the reinforcing face member are adhered and integrated to each other. When a shearing force parallel to the material is applied from the lateral direction, the cross-sectional area of the surface material that receives the shearing force becomes wider, and the proof stress of the surface material is improved.

Further, according to the small wall panel of the present invention, when the inorganic surface material is adhered, the reinforcing surface material is provided at the end portion, so that the bonding area when the inorganic surface material is attached is wide. Therefore, the bonding strength of the inorganic surface material is improved.

EXAMPLES The small wall panel of the present invention will be described in detail below with reference to examples. FIG. 1 is a diagram showing an embodiment of a small wall panel of the present invention, in which reference numeral 11 is a small wall panel. The small wall panel 11 is attached to the upper end portions of the end surfaces of the wall panels 2 and 2 that are partitions as in the conventional case, and is used to form an opening 4 serving as a doorway or the like in the lower portion of the small wall panel 11. Is.

As shown in FIGS. 2 and 3, the core material of the small wall panel 11 is such that vertical core materials 13 and 13 are provided at the left and right ends of the upper and lower horizontal core materials 12 and 12, respectively. Reinforcing core material 1 is provided on the center side of each of these vertical core materials 13, 13.
4, 14 are provided in the vertical direction. The horizontal core member 12,
On the front and back surfaces of 12, the cutout surface 1 is formed over the entire area from the position corresponding to the center side surface of the reinforcing cores 14, 14 to the left and right ends.
2a ... is formed. The notched surface 12a and the vertical core 1
3, 13 and the reinforcing cores 14, 14 are formed in a rectangular frame shape so as to be flush with each other on the front and back surfaces at both left and right ends.
In this way, the left and right ends of the front and back surfaces that are formed flush with each other,
The reinforcing face materials 15 ... Are adhered. The reinforcing surface material 15 ...
It is made of plywood, etc.
The upper and lower cutout surfaces 12a, the front and back surfaces of the vertical core member 13, and the reinforcing core member 1
It is attached so as to cover the front and back surfaces of No. 4. These reinforcing face materials 15 ... Are formed so that their outer side surfaces are flush with the front and back surfaces of the central portions of the horizontal core members 12, 12. Surface members 16 and 16 made of plywood are adhered and nailed to the outer surfaces of the reinforcing surface members 15 ...

In such a small wall panel 11, the reinforcing face materials 15 ... Are provided at the left and right ends inside the front and back face materials 16, 16, and the face materials 16, 16 and the reinforcing face materials 15 ... By being adhered and integrated, when a shearing force parallel to the face materials 16, 16 is applied from the lateral direction, it has excellent proof stress against the shearing force.

According to a second aspect of the present invention, in the small wall panel, the face material of the above-mentioned embodiment is an inorganic face material such as gypsum board. Since such a small wall panel has a large area of the surface on which the inorganic surface material is adhered, it is possible to obtain bonding strength that can withstand long-term use.

[0015]

As described above, in the small wall panel of the present invention, the reinforcing face materials are provided at both left and right inner sides of the front and back face materials, and the face material and the reinforcing face material are attached and integrated. Since the surface material is bent, when the shearing force parallel to the surface material is applied, the surface material is less likely to bend, and therefore cracks or other fractures do not occur, and it has excellent resistance to shearing force. Will be things.

The small wall panel according to the second aspect of the invention has a large bonding area of the inorganic face material, so that the small wall panel has sufficient bonding strength and can maintain its durability for many years.
