This invention relates to a method for manufacturing walls.
［従来の技術］
一般にゴミ焼却用のボイラやロータリーキルン等には、
第５図〜第７図に示すように複数の蒸気管或いは水管等

壁３両端に設けたヘッダである。[Conventional technology] Generally, boilers and rotary kilns for waste incineration have
As shown in FIGS. 5 to 7, a cylindrical pipe wall 3 is used in which a plurality of pipes l such as steam pipes or water pipes are arranged in a cylindrical shape and the pipes l are connected by fins 2. Note that 4 is a header provided at both ends of the cylindrical tube wall 3.

接を行うようにして製造していた。The above-mentioned cylindrical tube wall 3 has conventionally been constructed by arranging a plurality of tubes 1 in the circumferential direction along the headers 4, 4 between a pair of headers 4.4 spaced apart by the length of the tubes 1. Temporarily attach the tubes 1 to the header 4 by welding, then arrange the fins 2 between each tube 1, and temporarily attach the fins 2 to the tubes 1 by hand welding so that the whole becomes cylindrical. After that, the header 4, pipe 1, and fin 2, which were temporarily assembled into a cylindrical shape, were actually welded by hand.
［発明が解決しようとする課題］
しかしながら上記従来の円筒形管壁の製造方法には以下
のようケ問題点があった。[Problems to be Solved by the Invention] However, the above-mentioned conventional method for manufacturing a cylindrical tube wall has the following problems.

作業性が悪く、不必要な手間や時間が掛っていた。■ Since it is impossible to directly weld the tube 1 and fins 2 alternately so that the whole becomes cylindrical, we decided to temporarily assemble the loose tube 1 and fins 2 into a cylindrical shape and then perform the final welding. The work of temporarily assembling the loose tube 1 and fins 2 into a cylindrical shape was inefficient and required unnecessary effort and time.

きなかった。■ Loose pipes are the most time-consuming and most important part of the work.
The actual welding of the pipe 1 and the fin 2 is carried out with the tube 1 and the fin 2 temporarily assembled into a cylindrical shape, which is extremely technically difficult, and it is difficult to perform the actual welding automatically using a machine. As mentioned above, the actual welding had to be carried out manually, but since it is technically difficult to manually weld the pipe 1 and the fin 2, which were temporarily assembled into a cylindrical shape, it took a lot of work. It takes a lot of effort and time, and there are problems such as a high risk of uneven precision and distortion, and it has not been possible to manufacture the cylindrical tube wall 3 in a short period of time and with high quality.
本発明は上述の実情に鑑み、短期間のうちに高品質な円

製造方法にかかるものである。[Means for Solving the Problem] The present invention forms a planar tube wall by alternately welding tubes and fins, and applies plastic bending to the planar tube wall by pressing to form an arcuate tube wall. The present invention relates to a method of manufacturing a cylindrical tube wall, characterized in that a plurality of arcuate tube walls are combined into a cylindrical shape and welded.

業効率が向上する。In this way, the tubes 1 and the fins 2 are alternately welded to form a planar tube wall 5, and the planar tube wall 5 is plastically bent by pressing to form an arcuate tube wall 6. Since a plurality of the arcuate tube walls 6 are combined into a cylindrical shape and welded together, there is no need to temporarily assemble the separate tubes 1 and fins 2 into a cylindrical shape, which is the most labor-intensive and time-consuming process, and is also the most time-consuming. The important work of welding the separate tubes I and fins 2 alternately is done on a flat surface, which makes it much easier even when manual welding is required.Moreover, machine welding can also be performed, greatly improving work efficiency. improves.
