Description
Technical field
The utility model relates to a kind of elevated bridge railway roadbed supporting member for supporting track, is specifically related to a kind of pair of desk-top track traffic U type beam of support rail.
Background technology
Traditional elevated bridge generally adopts deck type box-shaped section component or T-shaped section structural member supporting track, and its defective is that the whole height of building is large, and space availability ratio is low, but generalization is not strong.
China's application 200810304445.3 discloses a kind of city track traffic U type beam, the beam body is linked to be the passage of U font cross section by the frange plate at the web of base plate, both sides and web top, the upper surface of base plate connects track, along beam body length to being fixedly connected with electric supply installation, electricity cable supporting mass and communicaton and signal cable supporting mass, the web of its both sides is asymmetric shape, wherein a side is the wall thickness webs such as curved arc shape, the frange plate of this coxostermum top connection is 7 shape frange plates, and flange is to the inside namely only arranged; Opposite side is that the curved arc shape of the grand drum in middle epimere outside, level and smooth thickening is not waited the wall thickness web, and the frange plate of this coxostermum top connection is T-shaped frange plate, namely has inside and outside two flanges.
Technique scheme adopts little U-shaped beam, and namely double track railway will adopt the U beam of two separation, and every double track railway beam will be transported twice, sets up twice.And the U beam rigidity of separating is little, is unfavorable for the noise reduction noise abatement.Adopt asymmetric two webs, design, construct and be more complicated.Also affected the whole view of bridge.In addition, little U beam has the twice web because double track railway is two little U beam juxtapositions in the middle of two-wire, can not adapt to branch-cut bridge.
China application 201110252862.X discloses a kind of urban railway traffic continuous basin type beam, its beam body is by bearing plate, the passage of the basin shape cross section that the frange plate at the epiplastron of bearing plate both sides and epiplastron top is linked to be, bearing plate is provided with at least two pairs of tracks, be fixedly connected with electric supply installation along beam body length direction, electricity cable supporting mass and communicaton and signal cable groove, the span of beam body is 40 meters～80 meters, the beam body is individual layer at the bearing plate of limit fulcrum section and span centre flat segments, all the other bearing plates of beam body are the box of remaining silent, and, between the individual layer bearing plate soffit of limit fulcrum section and span centre flat segments and the bottom surface of above-mentioned box for being connected smoothly.This beam is arranged on the double crossover section or needs to cross over the place of larger node, belong to a kind of bridge construction form that integrates the U-shaped beam of thin walled aperture and the box-girder of remaining silent, having solved the U-shaped beam of common rail traffic can't cross over larger node and can not in the problem of double crossover section application, enlarge the scope of application of U-shaped beam.
Although above-mentioned application provides a kind of urban track traffic beam with at least two pairs of tracks, a kind of continuous basin type beam, as shown in its accompanying drawing 1 and accompanying drawing 3, be a kind of bridge construction that integrates the U-shaped beam of thin walled aperture and the box beam of remaining silent in fact.But said structure exists and can not adopt prefabricated erection construction scheme, and the construction period is long, the poor quality controls, be difficult to promote the use of, cost is good, the Construction on Environment impact is large etc. exists the shortcomings such as processed complex, maintenance cost height.
