DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which an opening of a panel such as a wall panel used in a unit room or the like is reinforced, and more specifically, a structure for reinforcing the opening when the opening is cut into the panel. It is about.

[0002]

2. Description of the Related Art In a unit room such as a unit bathroom or a unit toilet room, a wall panel of the unit room is constructed by installing a wall panel in a building.

When a window is provided on the wall of the unit room, the window is often opened at the site in accordance with the sash attached at a predetermined position on the building site, and an assembler cuts the opening into the wall panel at the site. At the same time, the edge of the opening is reinforced with a rail-like reinforcing material.

FIGS. 5 to 8 show this conventional example. As shown in FIG. 5, a wall panel 10 includes a frame 12 and a board (for example, a tile) fixed to the front side of the frame 12 with an adhesive and screws. 14). The frame 14 is formed by combining and welding square pipes of aluminum or the like in a cross-girder shape.

When an opening for a window or a shelf is provided over two wall panels, an opening 16 is provided by cutting the sides of the wall panels 10 and 10 into a U-shape as shown in FIG. In order to reinforce the opening 16 of the board 14, a square pipe having the same thickness as the constituent material of the frame 12 is cut in accordance with the length of the edge of the opening 16, and the square pipe 18 is opened as shown in FIG. 1
6 is adhered to the back surface of the board 14 along the edge.

After the adhesive has dried, the square pipes 18 or the square pipes 18 and the existing frame 12 are connected by screws using a T-shaped fitting 20 and an L-shaped fitting 22 as shown in FIG. This is due to the fact that welding equipment is difficult to obtain at construction sites and special tools cannot be used. FIG. 8 (a) shows the connection structure of the portion A in FIG. 7, and FIG. 8 (b) shows the connection structure of the portion B in FIG.

The metal fittings 20 and 22 are fixed to the square pipe 18 or the frame 12 by screws 24.

As described above, by disposing the square pipe 18 at the edge of the opening 16 of the wall panel 10, the peripheral portion of the opening 16 is reinforced.

As another conventional example, Japanese Utility Model Laid-Open No. 6-66389 has been proposed.
The publication describes a structure in which a mold is fitted to an edge of an opening of a wall panel, and an embedded panel inserted into the wall panel is screwed to the mold.

[0010]

The conventional structure shown in FIGS. 6 to 8 has the following disadvantages.

[0011] A large number of joint fittings 20, 22 are required, and the material cost is high. Two or three screws must be formed for each of the fittings 20 and 22, and several tens of screws are required to reinforce one opening 16. For example, in FIG. 7, seven A portions and two B portions in one wall panel 10 are shown.
Screws are required in the part, 25 in total (7 × 3 +
2 × 2 = 25) screwing is required. Since the two wall panels 10 and 10 are reinforced, a total of 50 screwing operations are required, and the screwing operation is extremely time-consuming. Since the square pipe 18 is adhered to the board 14 with an adhesive, an adhesive is required, and it is necessary to wait until the adhesive dries, which takes time and effort.

In the conventional structure disclosed in Japanese Utility Model Laid-Open No. 6-66389, the reinforcement of the edge of the opening of the wall panel is weak. In particular, no reinforcement is provided at the intersection (corner) between the vertical side and the horizontal side of the opening, and cracks tend to spread from the corner to the board due to the impact force from the room.

An object of the present invention is to solve such various problems and to provide a reinforcement structure for a panel opening which is inexpensive, easy to construct, and has high reinforcement strength.
