Description
Technical Field
The utility model relates to a steel arch bridge technical field especially relates to a light prestressing force steel arch bridge.
Background
In the middle of present construction, need set up the temporary passageway at the job site, the construction of being convenient for, and the temporary passageway of setting up generally can adopt to set up console mode scaffold, so not only consumes a large amount of steel, and the security can not obtain the guarantee, and the job site condition is complicated changeable in addition, and the passageway position probably makes a lot of round trips change for traditional console mode scaffold sets up relatively difficultly.
Therefore, it is necessary to provide a new lightweight prestressed steel arch bridge to solve the above technical problems.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem provide a have set up simple and convenient, and be convenient for round trip movement, the dismouting work load is little, consumes steel few, the higher light prestressing force steel arch bridge of security.
For solving the technical problem, the utility model provides a light prestressing force steel arch bridge includes: a main beam; the two ends of the secondary beam are respectively connected with the main beam to form a bottom horizontal frame; one end of the steel wire rope is fixedly connected to the bottom of the main beam; the steel wire rope regulator is fixedly arranged on the main beam and is connected with the corresponding steel wire rope; the protective guard is fixedly arranged on two sides of the horizontal frame; and the channel plate is fixedly arranged on the main beam.
Preferably, after the steel wire rope is tensioned, the steel wire rope applies prestress to the main beam and enables the main beam to generate upward arch deformation.
Preferably, the main beam is I-shaped steel.
Preferably, the secondary beam is a round steel tube or a square steel tube.
Preferably, the channel plate is a patterned steel plate or a thick wood scaffold plate.
Compared with the prior art, the utility model provides a light prestressing force steel arch bridge has following beneficial effect:
the utility model provides a light prestressing force steel arch bridge mutually supports through girder, secondary beam, wire rope regulator, rail guard, access plate etc. sets up simple and convenient, and the round trip movement of being convenient for, and the dismouting work load is little, consumes steel few, the security is higher.
