Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of steel box-girder of steel structure bridge.
For achieving the above object, the utility model have employed following technical scheme:
A steel box-girder for steel structure bridge, comprises the support beam structure of two docking, three top boards and two base plates; Described support beam structure is made up of multiple dividing plates of welding on a web and its; Described each dividing plate top offers two two melting welding holes; In having between two two melting welding holes, a single melting welding hole is set; Described each the lower partition is provided with a V-shaped groove, and one of them the lower partition V-arrangement weld groove side is also provided with one and crosses welding hole; Described top board is divided into " ⊥ " type top board and two " ⊥ " type top board; Weld in two melting welding holes that the jag of described two " ⊥ " type top boards is inserted into two dividing plates respectively, tabula end is placed on single melting welding hole; Described two " ⊥ " type top board is after two dividing plate docking welding, and be inserted into by jag in remaining two two melting welding holes, described two " ⊥ " type top board transverse slat two ends are docked with " ⊥ " type top board respectively, are welded on dividing plate with one side supporting plate; Described base plate is also " ⊥ " type structure; Weld in the V-shaped groove projecting end of two base plates being inserted into respectively dividing plate; After two dividing plate docking welding, two " ⊥ " type base plate docking are by crossing welding hole welding with on dividing plate.
Advantage of the present invention:
1, the present invention improves efficiency of construction, boundary of works area, does not need manhole to enter people's interior welds, and casing inner air flow is better, more can effectively ensure that workman is healthy.
2, reasonable process of the present invention, ensures casing internal soundness, completes hidden pass weld.
