It talks about, there is certain opposite slippage between the first purlin column 10 and the second purlin column 20.
Further, before this step, it can also increase and pre-processing is done to the first purlin column and the second purlin column.
S2, the examination installation connector 40 to one boom 30 one by one, and one by one examination install the connector 40 to
Second purlin column 20 described in first purlin column 10/, wherein the fit dimension gap of the connector 40 and the boom 30 is
0.1mm-0.15mm, to ensure that the relatively described connector 30 of the boom 30 slides setting in axis direction and circumferencial direction.
In the step, during trial assembly, examine whether each constituent element meets assembly demand, for example, the first purlin
Whether have between column or the second purlin column and the mounting surface of connector 40 and well contacts；Cooperation between connector 40 and boom 30
Size gap whether meet demand, whether can be mutually shifted along axial direction therebetween, whether boom 30 can be opposite around axis
Rotation of connector 40 etc.；If being unsatisfactory for assembly demand, need to carry out repair to undesirable element above-mentioned to meet
Demand.
Step S3~S7 is the formal assembling process of truss structure.Whole booms and connector 40 and purlin column 10,20 are installed
The assembling process in hole is with the assembly of identical scheme.The following are detailed installation steps:
S3, after applying one layer of thin glue on the joint face of the boom 30 connecting with the connector 40, by the boom
30 with 40 pre-connection of connector；
S4, the boom 30 apply the connector 40 for being located at 30 both ends of boom with after 40 pre-connection of connector
Glue keeps it fixed with the first purlin column 10, the second purlin column 20 respectively；
S5, after the connector 40 is fixed to first purlin column 10, second purlin column 20, along the connector 40
The axially adjustable boom 30 and the connector 40 relative position,
S6, behind the relative position for adjusting boom 30 and connector 40, by the hole for injecting glue 41 toward the boom 30 with
Injecting glue in fit-up gap between the connector 40 guarantees that all peep holes 42 have glue spilling, and the connector 40
Also there is glue spilling at the crossover position of the boom 30, the glue of spilling is cleaned out；
S7 is fully cured to glue-line, and assembling finishes；
S8 removes the external support component for fixing first purlin column 10 and second purlin column 20.
In above-mentioned steps, step S1 and step S2 are without inevitable precedence relationship；If condition maturity, can also omit with
Upper two steps.When step S1 is omitted, step S8 can also be saved.
