20100086348 | METHOD OF JOINING CABLE RACKS, AND A SPLICE PLATE - Disclosed is a technique of joining two cable racks together in a longitudinal direction thereof. A splice plate is used which has two insertion holes each formed at a position corresponding to a first one of two joint holes in each of adjacent ends of each of two longitudinally-aligned pairs of primary beams of two cable racks, and two lock protrusions each formed at a position corresponding to the other second joint hole, in a manner engageable with the second joint hole. The adjacent ends of the longitudinally-aligned pair of primary beams are joined together by means of engagement between the lock protrusions of the splice plate and the second joint holes of the adjacent ends of the longitudinally-aligned pair of primary beams, and fastening between two bolt and two nuts through the first insertion holes and the insertion holes of the splice plate. Thus, two cable racks can be joined together by performing a bolting operation only at a single position in each of the adjacent ends of the longitudinally-aligned pair of primary beams. This makes it possible to reduce by half a time of joining operation while suppressing a trouble in the joining operation. | 04-08-2010 |
20100044524 | JOINT STRUCTURE OF CABLE RACKS - Disclosed is a cable rack joint structure, which is designed to bite into an inner peripheral surface of a bolt insertion hole so as to establish sufficient electrical conduction between cable racks. In the cable rack joint structure, a bolt insertion hole | 02-25-2010 |
