Description
Technical field
The present invention relates to a kind of elevated bridge railway roadbed supporting member that is used for supporting track.
Background technology
Known U type beam is that CN101120140A, name are called the Chinese patent application of " city track traffic U type beam " as publication number, and it is a track traffic single line U type beam, is only applicable to the bridge of about 30 meters of urban track traffic middle spans.At the double crossover section or when need crossing over big node, existing U type girder construction is stressed reasonable inadequately, so can't meet the demands, needs to adopt other beam type, and adopts other beam type, can influence view again, and this has just restricted the application of U type beam.
Summary of the invention
The purpose of this invention is to provide the continuous benzvalene form beam of a kind of urban track traffic, solve the problem that existing U type girder construction is stressed inadequately rationally, can't cross over big node, can not use at the double crossover section; And the bridge and the bad harmonious problem of U type beam view at solution double crossover section or big node place.
For achieving the above object, the present invention adopts following technical scheme: the continuous benzvalene form beam of a kind of urban track traffic, 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, described bearing plate is provided with at least two pairs of support rail platforms, be fixedly connected with electric supply installation along beam body length direction, electricity cable supporting mass and communicaton and signal cable groove, it is characterized in that: the span of described beam body is 40 meters～80 meters, the beam body is an 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.
The epiplastron of described bearing plate both sides is a symmetric figure, and for the grand drum in epimere outside, level and smooth curved arc shape of thickening are not waited the wall thickness epiplastron, the frange plate that the epiplastron top connects is a T shape frange plate.
Be fixed with noise barrier on the top of described frange plate.
Described communicaton and signal cable groove is on the bearing plate of the beam body between two pairs of support rail platforms.
Described electric supply installation is three rail electric supply installations, and three rail electric supply installations are fixed on the bearing plate of two pairs of beam bodies between the support rail platform.
Described electric supply installation is the contact net electric supply installation, include the contact net column, the contact net column is prestressed reinforced concrete column or steel post, and the contact net column is fixedly connected on the bearing plate of two pairs of beam bodies between the support rail platform, perhaps is fixedly connected on the frange plate of beam body.
Described contact net column adopts pre-embedded anchoring bolts flange connecting plate to fixedly connected with the beam body.
Described span centre fulcrum has one to two place.
Compared with prior art the present invention has following characteristics and beneficial effect: the present invention is arranged on the double crossover section or needs to cross over the place of big node, belong to a kind of bridge construction form that integrates the thin walled aperture U type beam and the box-girder of remaining silent, being a kind of improved elevated bridge railway roadbed supporting member, is a kind of overhead route that is applicable to urban track traffic contact net power supply mode and urban track traffic three rail power supply modes.The present invention can set up noise barrier, uncompensated contact net column and compensation contact net column be arranged on frange plate, also can set up uncompensated contact net column and compensation contact net column be arranged on the medium position of the bearing plate of beam body; The noise of this line and adjacent line also can be isolated, be stopped to the epiplastron of bearing plate both sides except that as the primary structure member, the double noise barrier of doing, and its inboard is laid with electricity cable supporting mass and communicaton and signal cable groove; Be furnished with track equipment on the bearing plate of beam body, make train on above-mentioned track, to advance, and can power to train by contact net electric supply installation or three rail electric supply installations.
The present invention is the multi-thread beam of a kind of track traffic, its beam body is more reasonable aspect structure stress, help the conduction of structure actual loading and power, more help bringing into play the anti-compression property of concrete structure, its torsional strength is big, be applicable to the bridge of about 40～80 meters of urban track traffic middle spans, the main material of its beam body is prestressed concrete, steel concrete, be a kind of form of structure that functions such as carrying, noise reduction and operation system are organically combined, can reach the purpose that reduces structure height and reduce vision, noise pollution simultaneously.With respect to the deck type beam bridge, the present invention can utilize bearing plate supporting track and train, reduces track absolute altitude and integral bridge height, reduces the influence to surrounding enviroment, prevents to go out bridge after the derail.But the beam body is the double as noise barrier simultaneously, helps reducing pollution from environmental noise; Equipment such as the communication of beam body disposed inboard, electric power, the space availability ratio height in whole cross section; Defencive function when the top flange of beam body has derail.Described contact net electric supply installation adopts the overhead contact line line, and power supply network and pantograph are unsettled, has maintenance personal's safety of walking, and safety is advantage preferably.
The invention solves bridge and the suitable problem that connects of track traffic U type beam at big node place and double crossover section, it can accomplish good suitable connecing with U type beam, realize the linear unification of view, and himself have all advantages that U type beam is possessed, and track absolute altitude and integral bridge height have been reduced, reduced influence, can prevent to go out bridge after the derail surrounding enviroment.
The present invention can cross over big node, also can use at the double crossover section, solved the problem that common U type beam can't be crossed over big node and can not use at the double crossover section, enlarged the scope of application of U type beam, solved common rail traffic U type beam and can not also solve bridge and the suitable problem that connects of track traffic U type beam in the middle problem that the contact net column is set of two-wire at big node place and double crossover section.
