Abstract

(57) [Abstract] [Purpose] To provide a wall panel with a corner structure having a waterproof structure. [Structure] The ends of the left and right side walls forming the corners of the panel are formed obliquely, a gap exists between the ends, and a waterproof member integrally molded of rubber is fixed to the back side of the corners. The sealing part that forms a part of the waterproof member penetrates the gap while reaching the end of the side wall and reaches the surface of the panel, and the umbrella-shaped part at the tip of the sealing part meets the left and right side walls. Covers the surface of the part. [Effect] Good waterproof effect and easy to manufacture. Further, since the surfaces of the joining portions of the left and right side walls are covered with the waterproof member, it is not necessary to precisely manufacture the panel structure of the corner portions.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wall panel, and particularly to a wall panel suitable for forming an outer wall surface, an inner wall surface, etc. of a building.

[0002]

[Prior art]

 In the construction of buildings and the like, it is becoming popular to construct the outer wall with panels. As one of such panels, as shown in FIG. 2, a composite plate in which metal plates 12 are laminated on both sides of a core layer 11 made of synthetic resin or a metal plate is formed by bending, and has a thickness of 2 to 5 mm. It is composed of a flat wall surface 3 and a short side wall 2 which is formed integrally with the wall surface 3 and hangs at a right angle from the peripheral edge of the wall surface. The one provided with the material 15 is used. When manufacturing a panel made of a composite plate, a notch 13 is formed on the back surface along a bending line to facilitate bending.

[0003]

[Problems to be solved by the device]

 In such a panel, a corner member 14 is provided on the back side of the corner portion and a sealing agent 16 is filled in the gap so that rainwater or the like does not enter from the corner portion, that is, the joining portion of the left and right side walls. . However, filling the corners with a sealing agent requires considerable skill. In addition, the sealant often leaks to the outside from the joining portions of the left and right side walls, and spoils the appearance. The present invention provides a panel for a wall whose corners have a waterproof structure without using a sealing agent.

[0004]

[Means for Solving the Problems]

 The wall panel according to the present invention comprises a flat wall portion and a short side wall which is formed integrally with the flat wall portion and hangs at a substantially right angle from the periphery of the flat wall portion. A panel for a wall surface comprising a panel main body to be exposed and a waterproof member fixed to a corner portion thereof, wherein the waterproof member is inserted into a gap formed between the abutting portions of the side walls and the back surface of the side wall. The wall panel is characterized in that it is formed of an elastic material, and is made of an elastic material. The waterproof member is preferably fixed to the panel body with an adhesive, but if a strong adhesive effect cannot be obtained, the adhesive may be used together with mechanical fixing with screws or screws. If there is no suitable adhesive, mechanical fixing such as a fixing tool may be sufficient.

The wall panel according to the present invention will be described in more detail with reference to the drawings. FIG. 1 shows an example of a corner portion of the panel according to the present invention. In the figure, 1 is a panel body, 2 is a side wall of the panel body, and 3 is a wall surface portion of the panel body. 4 is a waterproof member, 5 is a support portion of the waterproof member, 6 is an upper end of the support portion, and the width of the support portion 5 is usually 10 mm or more, preferably 10 to 30 mm. Although the thickness depends on the shape, it is preferably about 5 to 10 mm. It is preferable that the height of the supporting portion 5 is substantially equal to the height of the side wall 2, and it is preferable that the upper end 6 of the supporting portion 5 is brought into close contact with the back surface of the wall surface portion 3 of the panel main body when it is attached to the panel main body. Further, some hollow holes 7 are provided in the supporting portion 5 and the sealing portion 8, and when the waterproof member is attached to the panel body 1 by mechanical means such as the fixing tool 10, the supporting portion 5 is appropriately deformed by pressure. It is preferable to do so.

Reference numeral 8 is a sealing portion of the waterproof member. The sealing portion 8 extends outward from the joining portion of the left and right pieces of the supporting portion 5, enters the gap between the abutting portions of the side walls 2 and normally reaches the surface. The sealing portion 8 is in close contact with the abutting ends of the left and right side walls to seal the gap in a watertight manner. It is preferable to provide some hollows 7 in the height direction inside the sealing portion 8 as well to improve the close contact between the sealing portion and the end portion of the side wall 2. Further, when the film-shaped projection 18 is formed on the sealing portion 8 as shown in FIG. 3, the close contact with the end portion of the side wall 2 is further improved.

Reference numeral 9 denotes an umbrella-shaped portion provided at the tip of the sealing portion. When this umbrella-shaped portion 9 is provided, the surfaces of the meeting portions of the left and right side walls are covered and the meeting portions cannot be seen from the outside, so that the appearance is improved. In addition, the close contact with the surface of the side wall also contributes to the waterproof effect. In the structure shown in FIG. 4, not only the sealing part 8 is provided in the butting part of the side wall 2 but also in the groove 19 formed between the wall part 3 of the panel body and the side wall 2 formed by bending the side wall 2. The sealing portion 8 that enters is also provided. That is, the sealing portion 8 has a structure formed by extending in three directions from the corner portion.

Also, an example is shown in which the tip portion of the sealing portion 8 is formed in a groove shape and the packing material 20 formed of a flexible (elastic) material is pressed against the corner portion of the panel body. FIG. 5 shows an example of the structure of the waterproof member 4 when the butted portion of the side wall 2 is formed obliquely from the corner portion to form a so-called folded paper cut. Although the sealing portion 8 is provided only at the abutting portion of the side walls 2, the sealing portions 8 extending in the three directions from the corners as shown in FIG. 4 can be arranged in parallel.

It goes without saying that the waterproof member 4 is made of an elastic material, that is, a material having elasticity such as synthetic resin, natural rubber, synthetic rubber or the like, whereby the sealing and waterproofing are improved. The packing material 20 is preferably made of a material that is more flexible than the waterproof member 4. Further, the corner member 14 shown in FIG. 2 may be formed with an extension portion that extends outwardly from the side wall 2 (in the same direction as the lower piece of the angle member 15) in the lower portion of the waterproof member 4. It is also possible to enhance the sealing with the wall surface to be attached.

[0010]

[Effect of device]

 According to the present invention, there is provided a wall surface having a waterproof structure at the corners. In particular, according to the present invention, since the surface of the corner portion is covered with the umbrella-shaped portion of the waterproof member, the appearance is not spoiled even if the meeting portions of the left and right side walls are open or uneven. Therefore, when the panel body is manufactured, it is not necessary to form the end portions of the side walls at exactly 45 degrees so that the end portions of the left and right side walls are in close contact with each other at the meeting portion, which facilitates the manufacturing.
