Abstract

PROBLEM TO BE SOLVED: To prevent rusting to enhance the durability of a wall panel by forming at least the lower frame of a wall panel from a rust-preventive material, the wall panel being reinforced by securing of upper and lower frames and right and left vertical frames to the periphery of the back of a surface member. SOLUTION: Corner members 16 are secured to the four corners of a surface member 11 to firmly join the ends of upper and lower frames 12, 13 to the ends of right and left vertical frames 14, 14. In this case, an iron frame covered with a vinyl chloride resin to serve as a dustproof material is used, and a rectangular iron shape serving as the core of the lower frame 13 is covered on its outer peripheral surface with a vinyl chloride resin. Further, an inner iron shape is completely isolated from the outside by the vinyl chloride resin. Use of the iron frame covered with the vinyl chloride resin as the lower fame 13 of the wall panel 10 permits use on the wall surface of a bathroom, etc. Thus, even if the lower frame 13 retains water, rusting of the lower frame 13 is prevented to obviate the need for maintenance of the wall panel 10 and to enable the durability of the wall panel 10 to be secured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel used for forming a wall surface of a bathroom or the like.

[0002]

2. Description of the Related Art Conventionally, a wall panel which constitutes a wall surface of a bathroom unit or the like has a structure in which an upper, lower frame and left and right vertical frames are fixed and reinforced at a peripheral edge of a back surface of a face member. Japanese Patent Application Laid-Open No. 5-602 is used for the upper, lower and left and right vertical frames of this wall panel.
As described in Japanese Patent Publication No. 9, a light-weight steel made of iron or the like is generally used.

[0003]

However, in the conventional wall panel as described in the above-mentioned JP-A-5-6029, when it is used to form a wall surface of a bathroom, for example, The lower frame is always in contact with the floor of the bathroom due to its structure. Therefore, there is a problem that the lower frame portion is kept water against the intrusion of water or moisture such as steam, and the lower frame of the wall panel is made of iron, so that rust occurs over time. For this reason, maintenance such as repairing against rust is difficult due to the structure of the bathroom, and the durability is poor.

The present invention has been made by paying attention to the above-mentioned problems, and an object thereof is to solve these problems and to be used for forming a wall surface of a bathroom or the like. (EN) Provided is a wall panel in which rust does not occur in the lower frame even when the lower frame portion of the wall panel comes into contact with the floor surface of the bathroom to retain water.

[0005]

In the wall panel of the present invention, at least the lower frame does not rust in the wall panel reinforced by fixing the upper, lower and left and right vertical frames to the peripheral edge of the back surface of the face material. It is characterized by being made of a material.

Of the frame materials used in the wall panel of the present invention,
At least the rust-proof material of the frame material used for the lower frame is preferably made of iron coated with vinyl chloride resin, or synthetic resin formed by extrusion molding using vinyl chloride resin or the like. . In addition, in the wall panel of the present invention, a cement board is generally used as a face material used in a bathroom or the like.

[0007]

In the wall panel of the present invention, at least the lower frame is made of a material that does not rust in the wall panel in which the upper, lower and left and right vertical frames are fixed to the peripheral edge of the back surface of the face material. Therefore, even if the lower frame portion of the wall panel is in a water-retaining state, rust does not occur on the lower frame. Therefore, maintenance of the wall panel is not required and the durability of the wall panel can be improved.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of the wall panel of the present invention. In FIG. 1, a wall panel 10 of the present invention has a structure in which an upper frame 12, a lower frame 13 and left and right vertical frames 14, 14 are fixed and reinforced on a peripheral edge of a rectangular face material 11. This wall panel 10 is an example used to form a wall surface of a bathroom, and on the inner side surrounded by the upper frame 12, the lower frame 13 and the left and right vertical frames 14, 14 of the face material 11, The heat insulating material 15 is attached.

Further, corner members 16 are fixed to the four corners of the face material 11, and the end portions of the upper frame 12, the lower frame 13 and the left and right vertical frames 14, 14 are firmly joined.

In this embodiment, the lower frame 13 is made of an iron frame material coated with vinyl chloride resin as a material that does not rust. As shown in FIG. 2, in the lower frame 13, a vinyl chloride resin 13b is coated on the outer peripheral surface of a square steel mold steel 13a serving as a core material by extrusion molding or the like,
The inner steel mold steel 13a is completely shielded from the outside by the vinyl chloride resin 13b and is subjected to rust prevention treatment.

When the lower frame coated with the vinyl chloride resin is used, it is preferable to apply a resin or the like to the rustproof treatment on both ends of the cut.

Therefore, by using the iron frame material coated with the vinyl chloride resin for the lower frame 13 of the wall panel 10, it is used for the wall surface of a bathroom or the like, and the lower frame 13 is in a water-retaining state. However, rust does not occur on the lower frame.

FIG. 3 is a perspective view showing another example of the wall panel of the present invention. 3, the wall panel 20 of the present invention is shown.
Has a structure in which an upper frame 22, a lower frame 23, and left and right vertical frames 24, 24 are fixed and reinforced on the periphery of a rectangular face material 21.

The wall panel 20 is an example used to construct a wall surface of a bathroom, and is an inner side surrounded by an upper frame 22, a lower frame 23 and left and right vertical frames 24, 24 of the back surface 21. A heat insulating material 25 is adhered to the.

Further, corner members 26 are fixed to the four corners of the face member 21, and the upper frame 22, the lower frame 23, and the end portions of the left and right vertical frames 24, 24 are firmly joined.

In the present embodiment, the lower frame 23 is made of a vinyl chloride resin frame material as a material that does not rust. As shown in FIG. 4, the lower frame 23 has a rectangular cross-sectional shape, and is formed into a long length by extrusion molding or the like using a vinyl chloride resin. It is used as a material.

Therefore, by using the above-mentioned vinyl chloride resin frame material as the lower frame 23 for the lower frame 23 of the wall panel 20, the wall panel 20 is used as a wall surface of a bathroom or the like and the lower frame 13 retains water. However, rust does not occur on the lower frame.

[0018]

In the wall panel of the present invention, at least the lower frame is made of a material which does not rust in the wall panel in which the upper, lower and left and right vertical frames are fixed to the peripheral edge of the back surface of the face material. As a result, even if the lower frame portion of the wall panel is in a water-retaining state, rust does not occur on the lower frame, and therefore maintenance of the wall panel is not required and the durability of the wall panel can be improved. . Therefore, it is suitable as a wall panel.
