Abstract
The utility model belongs to the technical field of bridge structures, and particularly relates to a track beam and platform beam integration structure. The track beam and platform beam integration structure comprises a U-shaped beam serving as a track beam, and a first box beam and a second box beam which are respectively connected with two sides of the U-shaped beam and serve as platform beams, wherein two opposite web plates of the first box beam and the second box beam are integrally connected with two sides of a base plate of the U-shaped beam respectively and form edge web plates of the U-shaped beam. The track beam and the platform beams of the track beam and platform beam integration structure are integrated and are applied to an elevated lateral station in the urban mass transit, so that the shock absorption performance of a station structure can be effectively improved, the volume of the station structure is reduced, the economical efficiency and aesthetic effect are high, and requirements of a station bridge on the strength and the rigidity can be well met; the track beam and platform beam integration structure is conveniently and quickly constructed.
Description
Technical field
The utility model belongs to bridge construction technical field, is specifically related to one and is applicable to urban rail transit elevated side formula station rail beam platform beams integrative-structure.
Background technology
Existing overhead side formula station rail beam and platform beams are separately to walk abreast and arrange, rail beam bears live load of train effect, and platform beams bears crowd's load action.But there are some drawbacks in the mode that rail beam and platform beams are separately arranged in parallel: first, the space that such form of structure takies is larger, causes station scale to become large, is unfavorable for saving construction costs; Secondly,, in the time of earthquake, owing to not connecting between rail beam and platform beams, the effect that very easily bumps, causes rail beam and platform beams to occur to destroy and even collapses; Again, such form of structure has increased the scale of construction of whole overhead station, makes the overhead station that is positioned at earth's surface seem loftier, is unfavorable for landscape design.
Summary of the invention
The purpose of this utility model is exactly the deficiency existing in order to solve above-mentioned background technology, and a kind of rail beam platform beams integrative-structure reasonable, good economy performance of constructing is provided.
The technical solution adopted in the utility model is: a kind of rail beam platform beams integrative-structure, comprise first case beam and the second case beam as the platform beams that are connected with U-shaped beam both sides as the U-shaped beam of rail beam, respectively, described first case beam is connected with the base plate both sides one of U-shaped beam respectively with second case two relative web of beam, and two webs that described first case beam is relative with second case beam form the limit web of U-shaped beams.
Further, on described first case beam and second case beam, be equipped with building staircase hole.
Further, described first case beam and second case beam are the two chambers of single case beam.
Rail beam and platform beams are designed to overall structure by the utility model, and stressed clear and definite, structure rationally.In transverse compression the overall width of rail beam and platform beams, rail beam and platform beams are laterally linked together; On vertical, owing to adopting the form of U-shaped beam, reduce rail level absolute altitude, be equivalent to reduce the absolute altitude at whole station, reduce the construction costs at station and the running cost in later stage; Meanwhile, this overall structure can effectively be avoided the earthquake crash response between rail beam and platform beams, thereby improves the quake-resistant safety of overhead station.The perforate on platform beams of this structure arranges building staircase, has avoided building staircase plug-in, is conducive to landscape design and the architectural composition at whole station.
The utility model is applied in urban rail transit elevated side formula station, can effectively improve the anti-seismic performance of station structure, reduces the scale of construction of station structure, and economy and view are good, are well positioned to meet station bridge to intensity, rigidity requirement, convenient and quick construction.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and instantiation, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form and limit the utility model.
As shown in Figure 1, the utility model comprises the first case beam 2 as platform beams and the second case beam 3 that are connected with U-shaped beam 1 both sides as the U-shaped beam 1 of rail beam, respectively, two webs 4,5 that described first case beam 2 is relative with second case beam 3 are connected with the base plate 6 both sides one of U-shaped beam 1 respectively, and two webs 4,5 that described first case beam 2 is relative with second case beam 3 form the limit web of U-shaped beam 1 simultaneously.On described first case beam 2 and second case beam 3, be equipped with building staircase hole 7.
Base plate 6 between two limit webs of U-shaped beam 1 is as rail beam, hang a platform as platform beams in web both sides, two limits, the limit web of rail beam is the web of rail beam and the web of platform beams, in transverse compression the overall width of rail beam and platform beams, rail beam and platform beams are laterally linked together.On vertical, owing to adopting the form of U-shaped beam, reduced rail level absolute altitude, quite with reduced the absolute altitude at whole station, reduced the construction costs at station and the running cost in later stage.Meanwhile, this overall structure can effectively be avoided the earthquake crash response between rail beam and platform beams, thereby improves the quake-resistant safety of overhead station.On first case beam of this structure formation platform beams and second case beam, all offer building staircase hole, avoided building staircase plug-in, be conducive to landscape design and the architectural composition at whole station.
Rail beam platform beams integrative-structure is vertical, horizontal prestressed structure, and this structure is made up of U-shaped beam and two case beams, and case beam is the two chambers of single case beams.Total can adopt cast-in-place method that two structures are formed a whole and are applied to station, it is also conceivable that prefabricated setting up and the combination engineering method of cast-in-place construction, after beam prefabricated two casees in structure left and right, transport to station lifting construction, middle track plates is watered in rear reproduction in place.
The content not being described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
