Rack normal installation, tidy up the bottom chord grid first, secondly to CHS vertebral body upper chord equipment is good, should pay attention to the upper chord again after installation shall be such as to deal with all the screw, rack bottom chord is bent over too much, generally for two grid, lower chord node to solid, wait for the network frame structure stability, can get rid of the block of node, its surrounding supporting rack requires 6 ~ 8 a grid, can only be removed.

The network frame node is the place under great pressure in the whole. During the construction, the high-strength bolts should be handled in place then the bolts screws should be tightened.
