After complete, the intermediate node web of left node plate insertion web, welding intermediate node web and H-type arc component are finally assembled
The weld seam that wing web and two sides are put more energy into.This twice group welder's sequence, since each gusset plate plate thickness is thicker, and angle is smaller between each plate,
It must be allowed for access down after the assay was approved in strict accordance with assembling sequence and welding parameter welding to assembling procedure；
(6) web member between top boom is assembled referring to Fig. 7, referring to design drawing, the weld seam of branch pipe welded directly to the run pipe and supervisor；To guarantee
Hole is bolted not because welding deformation shifts, group welds the two sides end plate of H-type arc component, welded end plate and H-type arc component at this time
Wing web weld seam, and component is overturn 90 °, surrounding is set up support and is fixed, and is ready for subsequent assembly；
(7) the gusset plate positioning group of right side node is welded on the H-type arc component top flange plate of the rightmost side referring to Fig. 8,
Weld seam between welding node plate and with top flange plate；The gusset plate sealing plate of the then positioning assembling left and right sides, welding sealing plate and section
The weld seam of contact plate and top flange plate；
(8) after referring to procedure detection qualification on Fig. 9, lower boom positioning is assembled into the node sealing plate of the left and right sides
On, it is fixed in advance herein not influence the welding between subsequent each plate due to arranging the stiffener of double-sided symmetrical in node sealing plate herein
Web member between top-bottom chord in this region is carried out positioning welding by position；
(9) referring to Figure 10~12, the stiffener of the lower boom two sides between the node sealing plate of the left and right sides is assembled, stiffener is welded
Between and the weld seam with gusset plate, lower boom；Then each piece of stiffener of assembly and connection pin shaft part, due to pin shaft stiffener herein
It is smaller with node sealing plate spacing, pay attention to the welding quality of weld seam herein；After the completion of above-mentioned operation, between positioning welding top-bottom chord its
The web member in its region, the accessory structures such as finally group weldering pin shaft stiffening plate.
In addition to the implementation, all to use equivalent transformation or equivalent replacement the invention also includes there is an other embodiments
The technical solution that mode is formed should all be fallen within the scope of the hereto appended claims.
