Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in reinforcing structures for metal panels.

Usually, metal panels are formed into a square or rectangular box shape with ribs arranged around the perimeter, but before the ribs are placed around the perimeter, the perimeter of the panel is bent by a bender, so the surface of the panel concave distortion is likely to occur. However, it is said that a convex panel surface is more aesthetically pleasing than a concave panel surface. Therefore, in order to correct the strain caused by bending the panel and to form the panel surface into a slightly convex shape, conventional panel reinforcement structures include ribs placed around the periphery, as well as ribs arranged in a cross at the center of the back surface of the panel. The horizontal ribs push the vertical ribs, and the angle-shaped piece members (panel press plates) fixed to the horizontal ribs at certain intervals push the back side of the panel. Therefore, in the conventional panel reinforcement structure, not only the number of ribs increases, but also the piece members must be fixed to the ribs by welding or the like, which is extremely time consuming and costly.

It is therefore an object of the present invention to provide a reinforcing structure for metal panels that requires less material and is easier to construct.

The feature of this invention is that a single rib that has been pre-processed into an arched shape is installed vertically or horizontally on the back side of the metal panel so as to cross the center of the metal panel. The method is to form a convex surface, and will be explained below with reference to the drawings.

1 to 3 show a conventional metal panel, in which the periphery of a panel 1 is bent in advance into a predetermined shape, and ribs 2 are provided around the periphery. In the conventional reinforcing structure, as shown in the figure, vertical ribs 3 are pushed toward the surface side of the panel by horizontal ribs 4, piece members 5 are welded to the horizontal ribs 4 at appropriate intervals, and these piece members 5 are used to Since the back surface of the panel 1 was pressed by pressing the panel 1, the above-mentioned drawbacks occurred.

In the metal panel reinforcement structure according to the present invention, the fourth
As shown in Figures 7 to 7, one rib 6 is fixed to a metal panel 1 formed into a rectangular box shape with ribs 2 arranged around the periphery so as to cross approximately the center thereof. This rib 6 is connected to the panel 1 as shown in FIG.
It is pre-bent into an arched shape and has a predetermined bend before being fixed to. In the illustrated embodiment, the ribs 6 are provided vertically on the back surface of the panel 1, as seen in FIG. 4, but they may also be provided horizontally. Usually, the rib 6 is fixed as shown in FIG.
This is done by welding to the surrounding ribs 2 at both ends. 7 shows the welded joint.

As shown in FIG. 7, it is preferable for the rib 6 to have a U-shaped cross-sectional shape in terms of strength, but it is not necessarily limited to such a shape, and may have other shapes, such as a right-angled or I-shaped cross section. It may be a member of . The convex side of this rib 6 is panel 1.
It is fixed so that it is pressed against the surface.

Therefore, in the panel reinforcement structure of the present invention, the arched ribs 6 press the back surface of the panel 1 to make the surface convex, so that the concave distortion that occurs during the bending process of the panel is corrected. Moreover, the surface of the panel 1 is always maintained in a convex shape by the ribs 6.

As mentioned above, according to the present invention, in addition to the ribs around the panel, there is only one rib that crosses the center of the panel, so the number of ribs is small and the conventional piece member is not required, so the structure is extremely simple, saves material, and is easy to manufacture, resulting in significant cost savings. Further, there is a remarkable effect that the concave distortion of the panel can be appropriately corrected and the panel surface can be maintained in a desired convex shape.
