Abstract

DC60 (23/03/42) In a metal support catalog (20), as shown in Figure 4a, the end of the roll (28) is aligned. With the connected part (26) while in the catalog The metal support (20) In accordance with the illustration shown in Figure 4b, the end of the roll (28) is not aligned with the welded joint (26) according to this invention. Because the part that is not Being welded because the welded portion of the external cylinder (25) is overlapped with the un-welded part. Since the end of the roll will appear only one part of the unconnected part. In comparison with the frame Creation of a related Renaissance in which there are two unconnected parts. So that it is possible to make sure Sufficient effective welding length, also because the welding will be performed in the Where the end of the roll is arranged in line with the welded part It is possible to make an action Welding is convenient And therefore easily improve productivity In the metal support catalog (20) Following the shape shown in Figure 4a, the end of the roll (28) is aligned with the aligned weld (26), while in the support catalog at Metal (20) In accordance with the illustration shown in Figure 4b, the end of the roll (28) is not aligned with the welded joint (26) according to fabrication. Because the un-welded part due to the welded portion of the outer barrel (25) is overlapped with the un-welded portion, as the end of the roll only appears one un-welded portion. In comparison with the related renaissance structures that have two unconnected parts. So that it is possible to ensure sufficiently effective welding length, as well as because welding is performed in a condition where the end of the roll is aligned with the welded joint. close It is possible to make the welding operation more convenient. And therefore easily improve productivity

Claims (2)

1. The production method of the metal support catalog (20) consists of the procedure: preparation of the outer cylinder (25) formed by winding a flat sheet metal (21) into a cylindrical shape. And by joining the outer ends of the flat sheet metal together, the joins (26) and the honeycomb sections (23) are formed by winding the flat sheet metal (21). And corrugated metal sheets (22) that are overlapped on top of them form rolls; Which is characterized by: the measurement or prediction of the hollow depth at the end of the roll (28) of the honeycomb section (23): and Inserting the honeycomb part (23) into the outer barrel (25) in a state in which the end of the roll (28) is aligned with the aligned weld (26) and the banded weld of the section. Honeycomb (23) and outer cylinder (25) if the hollow depth is equal to or less than this specific value. 2. The metal support catalog (20) consists of: an external cylinder (25) that has been formed by winding a flat sheet metal (21) into a cylindrical shape. And by joining the outer ends of the flat sheet metal (21) together, the welded part (26), and the honeycomb part (23) that has been formed by winding the sheet. The flat (21) and corrugated sheet metal (22), which have been overlapped on top, form a roll. The aforementioned beehives (23), which has been inserted into the said outer barrel (25). Which has been made with the characteristics that The honeycomb part (23) has been welded as a banding to the outer barrel (25) and The end of the roll (28) of the honeycomb (23) section is aligned with the aligned weld (26) of such external barrel (25).
