Abstract
The invention relates to a replaceable concrete road bed device of a steel trussed bridge and a construction method. The device comprises a concrete road bed plate, a rail bearing table, a steel sole plate, shear nails and a rubber cushion block, and the device is fixed to the bridge floor through connecting parts. The construction method comprises the steps of: manufacturing a load transfer component and a main bridge at the same time; installing the main bridge; installing a replaceable concrete road bed formed by the steel sole plate, the shear nails and the concrete road bed plate; casting the rail bearing table; and connecting the replaceable concrete road bed with the load transfer component by the connecting parts. By using the replaceable concrete road bed device, in the process of using a bridge, the replaceable concrete road bed of a steel trussed bridge can be completely separated from the main bridge structure. When the bridge floor structure has a problem, the device can be replaced at any time. The use of the replaceable concrete road bed device of a steel trussed bridge can not affect the structures of a girder of the main bridge, and can not affect the maintenance of the main bridge structure. The rubber cushion block ensures that passengers can feel comfortable when a train runs on a bridge, and can decrease noise effect of the train during running on ambient environment.
Description
Technical field
The present invention relates to a kind of replaceable concrete road bed device of steel trussed bridge and job practices.
Background technology
The railway concrete ballast bed structure of large span steel truss bridge directly links to each other with the bridge deck of structure of main bridge on the Line for Passenger Transportation now, the working condition of railway concrete ballast bed structure directly influences the safety of structure of main bridge, causes the bridge deck maintenance difficulty of structure of main bridge after directly linking to each other simultaneously.The railway concrete ballast bed structure of large span steel truss bridge often adopts the ballast aggregate bridge floor in addition, and the structure dead load of itself is bigger.In order to improve the deficiency of above-mentioned bridge floor form, special invention steel bridge replaceable concrete road bed device.
Summary of the invention
The objective of the invention is at above-mentioned present situation, aim to provide a kind of structure of main bridge that do not influence, when bridge deck structure goes wrong, can be convenient for changing, and can guarantee train the time during comfortable, the train driving of passenger to little replaceable concrete road bed device of steel trussed bridge and the job practices of ambient noise influence.
The implementation of the object of the invention is, replaceable concrete road bed device of steel trussed bridge, by concrete road bed board and top support rail platform thereof, following steel sole plate constitutes, steel sole plate and concrete road bed board are affixed by WELDING STUDS, affixed by the Force transmission parts on connector and the bridge floor, under the steel sole plate rubber cushion blocks is arranged, rubber cushion blocks is on bridge floor.
The job practices of replaceable concrete road bed device of steel trussed bridge, concrete construction sequence is: when making main bridge, make Force transmission parts simultaneously, the main bridge of mounting strap Force transmission parts again, replaceable concrete road bed and the rubber cushion blocks of being made up of steel sole plate, WELDING STUDS, concrete road bed board is installed again, cast support rail platform links together with Force transmission parts replaceable concrete road bed with connector, and construction is finished.
Adopt the present invention, in the bridge use, replaceable concrete road bed device of steel trussed bridge can separate fully with structure of main bridge, and bridge deck structure can be changed when going wrong as required at any time.The use of replaceable concrete road bed device of steel trussed bridge does not influence each structure of main bridge girder steel, does not influence the maintenance of structure of main bridge yet.The passenger was comfortable when rubber cushion blocks guaranteed train operation, in the time of can reducing train driving to the influence of noise of surrounding environment.Adopt this device can reduce the engineering quantity of structure of main bridge.
Description of drawings
Fig. 1 is the replaceable concrete road bed device structural representation on the close crossbeam steel bridge deck bridge floor,
Fig. 2 is the replaceable concrete road bed device structural representation on the longitudinal and transverse beam system bridge floor.
The specific embodiment
Replaceable concrete road bed device of the present invention is by concrete road bed board 3 and top support rail platform 4 thereof, following steel sole plate 1 constitutes, steel sole plate 1 is affixed by WELDING STUDS 2 with concrete road bed board 3, affixed by connector 6 with the Force transmission parts on the bridge floor, rubber cushion blocks 5 is arranged under the steel sole plate, and rubber cushion blocks is on bridge floor.
Steel sole plate 1, WELDING STUDS 2 and concrete road bed board 3 are mainly as the load-carrying construction of railway loading, support rail platform 4 is as rail leveling and support rail parts, the effect of rubber cushion blocks 5 mainly is damping and noise reduction, the effect of connector 6 is that the Force transmission parts 7 that will increase newly in replaceable concrete road bed and the main structure is connected and fixed, the connector 6 main high-strength bolts that adopt, and can unclamp high-strength bolt when needs are changed the road bed board, removing needs the concrete road bed of replacing.
The concrete construction sequence of job practices of the present invention is: when making main bridge, make Force transmission parts 7 simultaneously, the main bridge of mounting strap Force transmission parts 7 again, replaceable concrete road bed and the rubber cushion blocks of being made up of steel sole plate 1, WELDING STUDS 2, concrete road bed board 35 is installed again, cast-in-site support rail platform 4, link together with Force transmission parts 7 replaceable concrete road bed with connector 6, construction is finished.
By replaceable concrete road bedly making at the construction field (site) that steel sole plate 1, WELDING STUDS 2, concrete road bed board 3 are formed, or factory makes.
The present invention adopts different forms according to the form of structure difference of main bridge bridge floor, to satisfy the needs of different bridge floors.
As the bridge floor of present close crossbeam steel bridge deck is adopted as shown in Figure 1 be form of structure.On the basis of former close crossbeam steel bridge bridge floor, increase Force transmission parts 7, corresponding member welding in Force transmission parts 7 and the close crossbeam steel bridge bridge deck.Force transmission parts 7 is with replaceable concrete road bed affixed by connector 6.
As the bridge floor of present longitudinal and transverse beam system is adopted as shown in Figure 2 be form of structure.The longeron upper body of the bridge of longitudinal and transverse beam system increases Force transmission parts 7, and Force transmission parts 7 is with replaceable concrete road bed affixed by connector 6.
