Abstract
The utility model discloses a concrete wind shield structure of a steel truss cable-stayed bridge for a railway and is aimed at effectively solving the problem of providing a wind screen on the steel truss cable-stayed bridge. A wind screen member is fixedly arranged between the upper outer side of an orthometric sketch plate (23) on a bridge floor and a saddle weight (20); the wind screen member is arranged on a vertical wall (21) of a sidewalk and the inner side of a web member (22); the wind screen member is composed of support members arranged at intervals and concrete wind screens (10) fixed on the support members, and the lower end of each support member is fixedly connected with the vertical wall (21) of the sidewalk.
Description
Technical field
The utility model relates to the Railway Steel Truss cable stayed bridge, particularly a kind of Railway Steel Truss cable stayed bridge concrete verge board structure.
Background technology
High speed development along with the railway cause; It is more and more that bridge is crossed over high wind districts such as valley or river; The wind speed conference exerts an influence to train operation; Train can slow down even out of service when serious, and weaken wind one of effective way of the influence of train operation is provided with verge board at the bridge windward side exactly.
At present, bridge verge board structure mainly contains following three kinds of forms.
Form one, and put formula bridge-type wind shielding structure.This wind shielding structure adopts wind shielding structure and the parallel setting of railroad bridge.Structure stress is simple, separately definite functions.Superstructure is by steel purlin formula spandrel girder and the steel plate be combined into that keeps out the wind with holes, and the side is anchored in ground with windproof cable and strengthens.
Pattern two: the paling form bridge wind shielding structure that is connected with the beam body.This wind shielding structure is located at the bridge cantilever end, is positioned at lateral rail place outside the sidewalk.Wind shielding structure is made up of the rolling fan-shaped verge board that forms of a plurality of identical steel sheets; Fan-shaped verge board road along the line direction is stood, is equidistantly arranged by root; Direction has vertical linkage on road along the line, fan-shaped verge board top, to increase the globality of wind shielding structure cooperative bearing.
Pattern three: the board-like bridge wind shielding structure that is connected with the beam body.This wind shielding structure is located at the bridge cantilever end, is positioned at the pedestrian guard rail place.Verge board is connected with column through bolt, and column is connected with beam retaining Zha Qiang.Bridge is established a side of wind shielding structure and is no longer established pedestrian guard rail, and the side walk slab places on the wind shielding structure column horizontal segment, and the side walk slab adopts the clad steel flase floor.
More than various bridge verge board structures all be used for concrete box girder, material is that the steel member constitutes, the later stage needs periodic maintenance, cost is higher.Place, Railway Steel Truss Stayed Cable Bridge dough figurine trade need be provided with saddle weight sometimes; Steel truss girder web member rod member has also occupied space, groups of people trade; The arrangement space of wind shielding structure on steel truss girder cable-stayed bridge is limited, and needs to be interrupted layout according to actual conditions, also need avoid the web member rod member.Above-mentioned verge board structure needs certain arrangement space, and for drawing logical the layout, all can't directly be used for steel purlin cable stayed bridge.
The utility model content
The utility model technical problem to be solved provides a kind of Railway Steel Truss cable stayed bridge concrete wind shielding structure, has solved the be provided with problem of verge board on the cable stayed bridge of steel purlin effectively.
It is following that the utility model solves the technical scheme that its technical problem adopted:
The Railway Steel Truss cable stayed bridge concrete wind shielding structure of the utility model; It is characterized in that: fixedly installing the verge board member between the outside, the saddle weight on the bridge floor quadrature sketch plate; The verge board member and be positioned at straight wall place, sidewalk and web member inboard; The verge board member is made up of supporting member that is provided with at interval and fixing concrete verge board on it, and each supporting member lower end is fixedly connected with the sidewalk straight wall.
The beneficial effect of the utility model is that concrete verge board and supporting member form overall structure, and are positioned on the straight wall of bridge floor sidewalk, have solved the be provided with problem of verge board on the cable stayed bridge of steel purlin effectively; Verge board adopts concrete plate, and cost is lower, helps practicing thrift construction investment.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
See figures.1.and.2; The Railway Steel Truss cable stayed bridge concrete wind shielding structure of the utility model; Be to fixedly install the verge board member between the outside, the saddle weight 20 on the bridge floor quadrature sketch plate 23; Verge board member and be positioned at sidewalk straight wall 21 places and web member 22 inboards, the verge board member is made up of supporting member that is provided with at interval and fixing concrete verge board 10 on it, and each supporting member lower end is fixedly connected with sidewalk straight wall 21.Concrete verge board and supporting member form overall structure, and are positioned on the straight wall of bridge floor sidewalk, have solved the be provided with problem of verge board on the cable stayed bridge of steel purlin effectively; Verge board adopts concrete plate, and cost is lower, helps practicing thrift construction investment.
With reference to Fig. 1 and Fig. 3, said concrete verge board 10 and saddle weight 20 level, concrete verge board 10 is staggeredly located with chord member scab 24.In order to keep integral bridge attractive in appearance, the color of verge board member is consistent with saddle weight 20.The top of concrete verge board 10 is provided with buckle 12, and buckle 12 is fixedly connected through rivet 13 with column 11.With reference to Fig. 3, said supporting member is made up of column 11 and bed plate 16, the lower end of column 11 and bed plate 16 welding, and bed plate 16 is connected with sidewalk straight wall 21 with pre-embedded bolt 15, and column 11 forms through bolt 14 with concrete verge board 10 and removably connects.
Some principles of the above the utility model Railway Steel Truss cable stayed bridge concrete wind shielding structure that just explains through diagrams; Be not be to the utility model be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
