<p>PROBLEM TO BE SOLVED: To perform easy and sure jointing of sub girders to each other at a corner using few number of part items. SOLUTION: This cable rack 3 includes crossing parts, which is formed by constructing a sub girder 2 between main girders 1 and sub girders 2 cross each other at a corner. At a crossing part 4 in which the sub girders 2 cross each other, a jointing member 7 is disposed which includes a first abutting surface part 5 abutted against the outer surface part of one sub girder 2 and a second abutting part 6 abutted against the outer surface part of the other sub girder 2. A recessed and protruding fitting part is formed at an abutted part, in which the sub girder 2 and the jointing member 7 are abutted against each other, and the sub girders 2 are jointed in a crossing manner via the jointing member 7.</p> |
