Claims

[Scope of Claim for Utility Model Registration] 1. Both ends of a pair of crossed seismic braces are attached to the main girder at both ends of the child girders at the front of the rising edge of the cable rack, and the ends of the seismic braces are connected vertically to the support metal fittings via support bolts and tightening nuts. An earthquake-resistant brace device for a cable rack, characterized in that the cable racks are supported at appropriate intervals in each direction. 2. The support fittings consist of a rack support fitting attached to the cable rack side and a pair of brace support fittings attached to each seismic brace side, and the rack support fittings and the brace support fittings are provided with at least bolt insertion holes for inserting support bolts. An earthquake-resistant brace device for a cable rack according to claim 1, further comprising: an earthquake-resistant brace device for a cable rack. 3. The support fitting has an outer bent piece on one side edge for contacting the outer surface of the main girder of the cable rack, and has support pieces with brace support holes for supporting both ends of the seismic brace on both corners of the other side edge. 2. The seismic brace device for a cable rack according to claim 1, wherein the outer bent piece projects in the opposite direction, and bolt insertion holes for inserting support bolts are formed at both ends. 4. Use only a pair of brace support metal fittings, and insert hexagonal head support bolts from the child girder side into the bolt insertion holes of each brace support metal fitting and the mounting holes drilled in the child girder of the cable rack. The seismic brace device for a cable rack according to claim 1, wherein the seismic brace device for a cable rack is supported on the support bolt via a tightening nut. 5 The support bolt is a support plate with a cross-sectional shape of a hat with support pieces with bolt insertion holes protruding from both ends, or a support plate with support pieces with bolt insertion holes protruding from both ends and the inner end is locked to the back side of the child girder. Claim 1, claim 2, or claim 2, comprising a pair of support plates each having a protruding piece, and a support bolt with a hexagonal head inserted through a bolt insertion hole of each support piece and supported by a tightening nut. 3
Earthquake-resistant brace device for cable racks as described. 6. A support plate with a lip Z-shaped cross section, on which the support bolt has a support piece with a bolt insertion hole protruding from one end and a locking piece protruding to the inside of the main girder from the other end;
