Abstract
An object of the present invention is to increase the dimensional accuracy of a structure including a plurality of rectangular pipes. A structure (6) includes a plurality of rectangular pipes (60) joined together. The plurality of rectangular pipes (60) include a first rectangular pipe (60a) and a second rectangular pipe (60b) joined by welding. Two or three of four sides that constitute an end face (62) of the first rectangular pipe (60a) are joint sides (62a) welded to a side face (63) of the second rectangular pipe (60b), whereas the rest of the four sides is a non-joint side (62b) separated from the side face (63) of the second rectangular pipe (60b) by a gap.
Claims6
A structure comprising:
- a plurality of rectangular pipes joined together, wherein
- the plurality of rectangular pipes include a first rectangular pipe and a second rectangular pipe joined by welding, and
- two or three of four sides that constitute an end face of the first rectangular pipe are joint sides welded to a side face of the second rectangular pipe, whereas a rest of the four sides is a non-joint side separated from the side face of the second rectangular pipe by a gap.
A method of producing a structure including a plurality of rectangular pipes joined together, the method comprising:
- positioning a first rectangular pipe and a second rectangular pipe by placing the first rectangular pipe and the second rectangular pipe along a jig for positioning such that four sides constituting an end face of the first rectangular pipe face a side face of the second rectangular pipe with a gap therebetween;
- and
- welding only two or three of the four sides that constitute the end face of the first rectangular pipe, the four sides facing the side face of the second rectangular pipe with the gap therebetween, to the side face of the second rectangular pipe.
