<p><P>PROBLEM TO BE SOLVED: To provide a splice structure of a cable rack which can achieve sufficient electric conduction by expanding a bolt insertion hole, ensure work efficiency of coupling work by positively preventing co-rotation occurring in fastening a bolt and nut, and attain safe work at a high position. <P>SOLUTION: A distance between opposite sides of the bolt insertion hole 9 or a length of the shortest portion of a diameter thereof is formed to be larger than the distance between opposite sides 6A of a corner root 6 in a splice bolt 5, so that the entire corner root 6 can be formed insertably. The distance between the opposite sides 9A of the bolt insertion hole 9 or the length of the shortest portion of the diameter thereof is formed to be shorter than a distance of a diagonal of the angle root 6. The bolt insertion hole 9 is provided so as to be expanded on a portion where corner portions 6B are engaged. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
