Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a method for manufacturing decorative bodies for use in gates, fences, and grids.

Prior Art Conventionally, in order to assemble decorations used for gates, fences, and grids using aluminum extruded sections, the anodized or painted extruded sections are cut, the cut sections are processed as appropriate, and then connected. The work involved repeating the process of attaching blocks and other parts and then assembling them.

Prior Art The conventional manufacturing methods described above have the following drawbacks.

■ Since an extruded shape that has already been anodized is cut, the aluminum base material may be exposed at the cut portion and corrode from the base material.

@ Also, since we process, attach parts to, and assemble shapes that have already been treated with alumite, scratches may occur on the surface of the shapes during the process.

Means for Solving the Problems The method for manufacturing a decorative body according to the present invention is to form a unit body by integrating a frame material having a welded protrusion and a decorative material by welding the current-carrying contact portion that is the abutting portion of both. Then, the unit body is alumite treated in an alumite treatment tank or painted.

Since the cut sections are welded to form a unit body, and the unit body is alumite-treated or painted, the base material of the cut portion is also alumite-treated and does not corrode.

After the unit body is formed, it is alumite treated or painted at the end, so any scratches caused during processing or other processes will not appear on the surface of the decorative body.

EXAMPLE Hereinafter, the present invention will be explained in detail based on an example shown in the drawings.

In FIGS. 1(A) and 1(B), reference numeral 1 indicates a frame material obtained by cutting an extruded aluminum profile. The frame member 1 has a hollow portion 2 having a rectangular cross section, and a protrusion 6 extending in the longitudinal direction from one side of the hollow portion 2 in the width direction. A round bar-shaped welding protrusion 4 is formed at the tip of the protrusion 3.

With the welded protrusions 4, 4 of the frame members 1, 1 facing each other,
The frame members 1, 1 are arranged parallel to each other left and right.

At this time, the welding protrusions 4, 4 of the frame members 1, 1 are placed on the electrode 6 of the welding device 5.

A decorative material 7, which is a round bar-shaped extruded aluminum ram member, is placed between the left and right frame members 1,1. First, a plurality of vertical decorative members 7a are placed on the electrodes 6 in parallel with the frame members 1, 1, separated by an appropriate distance between the left and right frame members 1,1. Next, a plurality of horizontal decorative members 7b are placed perpendicularly to the vertical decorative members 7a. The left and right ends of the horizontal decorative material 7b are placed on the current-carrying contact parts 4, 4 of the frame members 1, 1, and the intersection with the vertical decorative material 7a is directly above the electrode 6. As described above, the vertical decorative members 7a and the horizontal decorative members 7b are arranged in a grid pattern. At this time, the intersections of both the intersections of the vertical decorative material 7a and the horizontal decorative material 7b become the current-carrying contact portions 8. Further, the contact point of the horizontal decoration member 7b with the welding protrusions 4, 4 of the frame member 1.1 becomes the current-carrying contact portion 8. (FIGS. 2A and B) The electrode 6 is brought into contact with the horizontal decoration member 7b from directly above each current-carrying contact portion 8, facing the lower electrode 6. In this state, electrode 6 to electrode 6
