Description

[Detailed Description of the Invention] The present invention relates to an improvement of a surface-finished metal plate wall panel.

Conventionally, wall panels using surface-finished metal plates have been constructed by drawing and bending all four curved corners, or by cutting out, bending, and then welding the four curved corners.

However, when processing wall panels with relatively large side walls, forming by drawing and bending requires separate mold equipment for each panel shape and size, as well as a fairly large and powerful press machine. There were many similar problems, and this was one of the reasons for the cost increase.

In addition, in the case where the four curved parts are welded, additional work such as welding finishing is required, which causes problems in the design of the corner parts in particular, and there are also problems in water-blocking properties and strength from pinholes in the welded parts. There are several disadvantages, such as the occurrence of problems, and improvements to these have been strongly desired.

The present invention has been devised to solve the above-mentioned disadvantages, and the four corner curved portions of the surface-finished metal plate wall panel are formed into a non-drawn portion having an upper drawing bend forming portion l and a lower notch 5 or notch portion 4. This is a wall panel consisting of m.

The following will explain based on the drawings.

In general, wall panels made of surface-finished metal plates are used as exterior, ceiling, and interior panels of buildings, etc. Especially when used for exterior purposes, the structure shown in Figure 1 is used to house the ceiling joint. taken.

Therefore, especially when used for exterior purposes, the four corners of the panel are required to be completely bonded due to issues such as water barrier properties and strength.

Therefore, the conventional wall panel as shown in Fig. 2, in which the four corner curved parts are cut out and welded after the bending process, is particularly disadvantageous in terms of design because the welded parts are exposed on the surface. Furthermore, it was insufficient to meet requirements such as water barrier properties and strength.

On the other hand, wall panels with drawing processing on the four corners do not have the above-mentioned drawbacks, but as already mentioned, they do have drawbacks such as the need for mold equipment and large press machines, and they are also expensive to manufacture. becomes.

In contrast, in the present invention, the four corner curved portions of the surface-finished metal plate wall panel have an upper drawing bend forming part l and a lower non-drawing part m having the lower notch 5 or notch part 4.
This is a wall panel that advantageously solves these problems.

Next, the present invention will be explained in detail with reference to embodiments shown in FIGS. 3 to 8. In the figure, the top plate 2 side of the side wall portion 3 is the upper part l, and the open side is the lower part m.

The wall panel of the present invention as shown in the example has a drawing process at the top, so even if the panels are jointed with a sealant, the exposed corner parts have excellent design in terms of appearance, and the four corner curved parts It does not have the disadvantages of wall panels that are finished by welding, such as water barrier properties and strength, and does not require additional work such as welding.

On the other hand, the wall panel of this invention does not require individual mold equipment or large press machines for each panel shape and size, unlike wall panels that draw all four curved corners, and does not require a large press machine. By combining molds that narrow the four corners of the panel, drawing processing similar to press drawing can be obtained, and by changing the length of the mold of the bender processing machine to each dimension, various types of drawing processing can be obtained. It is possible to easily manufacture panels of any shape and size.

Furthermore, with the wall panel of the present invention, there will be no machining damage to the finished surface of each material-specific surface-finished metal plate. Furthermore, as a result, it is possible to reduce the cost of the product and save labor in manufacturing and processing the panels.

As described above, according to the present invention, excellent wall panels can be provided easily and inexpensively. In addition, by using special metal fittings and using the notches or notches in the four curved corners of the panel, it is possible to easily install the panel, and this method can also be developed to be used not only for wall panels but also for ceiling panels, etc. It is possible and the effect is great.
