Description

[Detailed description of the invention] * Industrial application field The present invention relates to accessory panels such as ultra-durable fluororesin-coated steel plates used as caps, drains, external corner panels, internal corner panels, etc.

*Problems to be solved by conventional techniques and ideas In forming such utility panels, in the past, deep cuts were made in advance in the rising walls at the corners of the panels, reaching from the edges to the base. The method used was to bend the panel and then weld the notches. However, especially in the case of accessory panels made of fluororesin-coated steel plates, it is necessary to coat the surface with fluororesin paint after welding, which is a troublesome task that increases costs.

On the other hand, when forming the accessory panel, the above-mentioned problem can be solved if the blank is drawn using a press, but in this case, a large-sized press is required. Therefore, this is not suitable for use in small-volume production panels of a wide variety of types.

The present invention has been made in an attempt to solve the above problems all at once and provide an inexpensive accessory panel.

*Means for solving the problem In order to solve the above problem, the accessory panel provided by the present invention has a substantially inverted V-shaped notch extending from the edge of the rising wall toward the base of the rising wall. An extraction hole independent from the notch is provided between the notch and the base,
It is characterized in that a constricted portion is formed between the extraction hole and the base.

*Example Reference numeral 1 is the rising wall of the panel. rising wall 1
Rising from the edge 2 of the wall 1 toward the base 3 of the wall 1
A notch 4 in the shape of a shape is provided. Opening angle a of the notch 4
(Figure 1) is preferably slightly larger than 90°. An extraction hole 5 independent from the notch 4 is provided between the notch 4 and the base 3. The punching hole 5 may be, for example, a single slit of various shapes (FIGS. 1, 5, and 7), or may be, for example, a plurality of mutually independent through holes (FIG. 3). A constricted portion 6 is provided between the extraction hole 5 and the base portion 3.

* Effect When the above panel is bent with a press bender, both edges of the notch 4 come close to each other, and the narrowed part 6
is squeezed, and the wrinkles caused by the squeezing are absorbed by the punched holes 5. The hatching part in Figure 6 is caulked 7 to prevent rainwater from entering and to improve the appearance.
Indicates the location of Incidentally, Figures 9 and 10 show an example in which the present invention is applied to Kasagi.

*Effects of the invention Since the accessory panels of this invention are processed by a combination of drawing and bending, there is no need for welding, coating, etc., and there is no need to use a large press, and a small press bender is sufficient. It can be processed into Therefore, even accessory panels of various types and produced in small quantities can be provided at low cost.
