Description
Technical field
The utility model relates to a kind of elevated bridge railway roadbed supporting member that is used for supporting track.
Background technology
Traditional elevated bridge generally adopts deck type box-type section member or T type section structural member supporting track; Its defective is that the whole height of building is big, and casing sympathetic response noise is arranged, and passes the residential district and need add a large amount of sound barriers; Not only bigger to the civic landscape influence, and construction and operation cost height.And if derail, train is gone out bridge easily, and neighboring buildings and people are caused harm.Known U type beam is that CN101120140A, name are called the one Chinese patent application of " U-shaped that is used for railroad track is striden part " like publication number, and its shortcoming one is the single line beam; General two-wire overhead route is made up by two single line beams; Two beam base plate broads, floor space is big, and closely landscape effect is slightly poor; The 2nd, as the full wafer precast beam; Need whole ground pallet to establish; Whole beam is had relatively high expectations to road transport condition along the line and load carrying capacity of bridge from great, and existing bridge construction sometimes needs reinforcement; Or need many row's wheel shaft Beam transportation vehicles, the transportation of the integral prefabricated beam of road incompatibility of some technical condition difference.And the similar railway trough girder of the big U beam of two-wire is stressed unreasonable, can not intercept adjacent line wheel track noise, and these defectives have restricted the application of U type beam.
The utility model content
The purpose of the utility model provides a kind of urban track traffic three rail power supply mode mountain type beams, solve that traditional box beam building height is big, casing has sympathetic response noise and structure itself not to intercept to face line wheel track noise problem; And solve noise and the inconvenient problem of traditional little U type beam whole Transporting that two-wire large U type girder construction is stressed inadequately rationally, can not intercept the adjacent line wheel track.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of urban track traffic three rail power supply mode mountain type beams; Its beam body is the passage that the limit web T shape frange plate by the limit web of base plate, base plate both sides and web top, limit is linked to be; Said base plate is provided with two pairs of support rail platforms, is fixedly connected with electric supply installation, electricity cable supporting mass and communicaton and signal cable supporting mass along beam body length direction, it is characterized in that: said electric supply installation is the three rail electric supply installations that are fixed on the base plate of beam body; The span of said beam body is 25 meters～35 meters; The middle part of the base plate of beam body, be provided with median ventral plate along beam body length direction, median ventral plate T shape frange plate is arranged at the median ventral plate top, and described two pairs of support rail platforms are symmetricly set on the base plate of both sides of median ventral plate.
Said communicaton and signal cable supporting mass is connected on the both sides sidewall of median ventral plate.
The limit web of said base plate both sides is a symmetric figure, for the grand drum in epimere outside, level and smooth curved arc shape of thickening are not waited wall thickness limit web.
Said support rail platform and beam body one-time-concreting are accomplished, and become the part of structure stress.
Can be fixed with noise barrier on the top of said limit web T shape frange plate.
Compared with prior art the utlity model has following characteristics and beneficial effect: the utility model is a kind of track traffic two-wire beam; Compare with traditional two-wire U beam, the one, structure stress is more reasonable, helps the conduction of structure actual loading and power; Said median ventral plate and median ventral plate T shape frange plate have strengthened concrete structure pressure zone area; More help bringing into play the anti-compression property of concrete structure, the beam body can not only be saved material, and can improve torsional strength; The 2nd, median ventral plate can play the effect that intercepts adjacent line wheel track noise; The 3rd, median ventral plate and median ventral plate T shape frange plate can be used as the braced structures of laying apparatus cable testing bridge, also can be used as passenger's emergency evacuation passage.
The utility model belongs to a kind of thin walled aperture mountain type beam, is a kind of improved elevated bridge railway roadbed supporting member, is a kind of overhead route that is applicable to the logical three rail electric supply installations of urban track traffic, can set up on the noise barrier Yushan Hill type beam flange plate simultaneously; The noise of this line and adjacent line also can be isolated, stopped to said web except that as the primary structure member, the double noise barrier of doing, and relative box beam has reduced the use amount of sound barrier, has improved the landscape effect of overhead route; Electricity cable supporting mass and communicaton and signal cable supporting mass can be laid in its inboard; But deployment rails equipment on the said base plate makes train on track equipment, to advance, and can supply power to train through three rail electric supply installations.
The beam body of the utility model is the mountain type, is a kind of lower support type beam bridge, is applicable to 30 meters left and right sides bridges of urban track traffic middle span.The main material of said beam body is prestressed concrete, steel concrete, is a kind of form of structure that functions such as carrying, noise reduction and operation system are organically combined, and can reach simultaneously to reduce structure height and the purpose that reduces vision, noise pollution.With respect to the deck type beam bridge, the utility model can utilize bearing plate 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 web of girder is the double as noise barrier simultaneously, helps reducing pollution from environmental noise; Equipment such as the communication of girder disposed inboard, electric power, the space availability ratio in whole cross section is high; Said T shape frange plate can be used as access path and passenger's emergency evacuation passage, the defencive function when having derail simultaneously, and in addition, the maintenance personal also can safety walking on T shape frange plate.
The utility model can adopt precast segment, bridge formation machine on-site consolidation erection construction technology, and each sections deadweight is little, and is less demanding to road transport condition along the line and load carrying capacity of bridge, and convenient transportation can be applicable wider.Part of nodes can adopt on-the-spot full framing pouring construction process.Also can adopt integral prefabricatedly when having ready conditions, transport beam on the beam, the construction technology of integration of transporting and building.
