Abstract
The invention relates to a bridge beam arch rib section manufacturing process. The manufacturing process comprises the three steps of truss piece splicing, wind bracing transverse combination splicing and integral section splicing. The bridge beam arch rib section manufacturing process has the advantages that multi-section matching and splicing are adopted, and for each section, related components can be matched and spliced by means of specific jig frames, so that line-type precision of arch rib sections is ensured; labor amount of integral pre-assembly of the bridge beam arch rib sections is reduced, the splicing period is shortened, and working efficiency is promoted.
Description
Technical field
The invention belongs to bridge manufacturing technology field, particularly a kind of bridge arch rib section manufacture craft.
Background technology
Increasing along with China railways, expressway construction project, builds at the deep mountain valleys that natural conditions are poorThe engineering of bridge has got more and more, and especially long-span steel arch bridge flows urgency, construction environment deeply because this structure is particularly suitable for paddySevere area, valley, plateau. Therefore for the preparation method of bridge arch rib, also come into one's own more and more, particularly forThe disadvantageous situation of execution conditions, its preparation method just seems particularly important.
In the bridge of the present invention's research, main bridge adopts the double-deck trussed bridge of half-through, is arranged as 496m, bridge main line across footpathBe divided into by function upper and lower two-layer, upper deck of bridge server motor-car, beam overall 33m; Lower floor's bridge service system of going slowly, width 12m, mainIn spanning, 108m lower floor bridge floor can be removed to both sides by the vertical shift track being suspended at the bottom of upper deck of bridge beam, to meet 500t levelShip navigation requirement; In the time of lower floor's bridge floor closure state at ordinary times, at the bottom of beam, about 300m scope meets yacht navigational clearance height; AndArch rib section is wherein also structure composition indispensable in bridge. Find through retrieval, China Patent No. is201310367055.1 have proposed a kind of bridge arch rib preparation method, comprise the following steps: 1) blanking typesetting; 2) blanking; 3) volumePipe; 4) the inner reinforcement of assembly welding; 5) put ground sample, assembling steel pipe; 6) determine suspension rod position, taking dotting punch as mark; 7) suspension rod positionErection support welding; 8) welding tube and tube butt weld; 9) assembly welding arch rib; 10) horizontal, bearing diagonal is made; 11) sectional making alsoCarry out assembled in advance; 12) mark is carried out in arch rib segmentation position, same first code that connects; 13) paint; Adopt the party brightMethod, carry out bridge arch rib making and assembled in, simplified flow process, also significantly improved assembled and welding quality simultaneously,Greatly ensure the construction quality of bridge arch rib; But there is following shortcoming in this preparation method: 1. this bridge arch rib preparation method,What adopt is steel pipe, but steel tube section uses steel more, and manufactures relative complex, connects inconvenient; 2. this preparation method, noCan meet the requirement of arch rib section multi-segmental being mated to assembled making, in arch rib section manufacturing process, line style camber requires high simultaneously,But the wayward line style camber of this preparation method.
Therefore, developing the bridge arch rib section manufacture craft that a kind of preparation method is simple, easy to operate and line style precision is high isBe necessary very much.
