Step 1. prefabricated components 3 it is prefabricated：The outer framework of regular hexagon is welded into using six blocks of planks 7 in precast factory
4, the length of plank 7 can need that different length, 7 thickness of plank and height is taken to take according to structure stress calculating according to construction profile
Value, in the inside of outer framework 4, the upper diaphragm plate 9 of setting, lower diaphragm plate 10 and ribbed stiffener 8 prevent its local buckling, in outer framework 4
Lower end install lower cover 6；
The connection of step 2. prefabricated components 3：Prefabricated components 3 are transported at bridge site place, first by the prefabricated of innermost layer
Component 3 is connected with bridge pier 1, can according to circumstances select bolt or welding, while it is most interior to use high-strength bolt that will be located at anchor plate
Layer six prefabricated components 3 be fixed together, then along radial direction of bridge pier 1 from the inside to the outside by spanning 2 preset shape to its into
Row splicing, and be fixed by high-strength bolt and anchor plate, after the molding of spanning 2, upper cover is installed on each prefabricated components 3
Plate 5.
As shown in fig. 6, when bridge pier 1 is 2, many places can be carried out to spanning 2 and constructed simultaneously：It is selected at each bridge pier 1
It uses the prefabricated components 3 for prefabricated components 3 as the innermost layer that six numbers are 1 to be connected first with bridge pier 1, while using high-strength bolt
It will be fixed together positioned at the six of innermost layer prefabricated components 3 with anchor plate, then press spanning from the inside to the outside along the radial direction of bridge pier 1
2 preset shape splices it, i.e., carrying out prefabricated components 3 according to number 2~9 successively is spliced to form moulding shown in Fig. 6
2 structure of spanning of honeycomb structure.
Since prefabricated components 3 use on-site consolidation mode, different bridge spans, bridge can be determined according to bridge functional requirement
2 shape of beam width and spanning.Due to the limitation of current material property, 2 structure of spanning is suitable for the urban human row of Medium and small span
Bridge is not particularly suited for the bridge compared with large span and larger load.
