Description

Construction structure is erect to suspension bridge stiffening beam

Technical Field

The utility model relates to an erect construction technical field, specifically be a suspension bridge stiffening beam frame facility worker structure.

Background

Suspension bridge, also known as suspension bridge, refers to a bridge with cables (or steel chains) suspended by cable towers and anchored to both banks (or ends of the bridge) as the main load-bearing members of the superstructure. The cable geometry is determined by the equilibrium condition of the forces, typically approaching a parabola. A plurality of suspension rods are suspended from the cable to suspend the deck, and stiffening beams are often disposed between the deck and the suspension rods to form a combined system with the cable to reduce deflection deformation caused by loading.

The suspension bridge is a bridge using a cable rope or a chain rope bearing tension as a main bearing component and comprises a suspension cable, a cable tower, an anchorage, a suspender, a bridge deck system and the like. The main bearing member of the suspension bridge is a suspension cable which mainly bears tension and is generally made of steel (steel wires, steel cables and the like) with high tensile strength. The suspension bridge can fully utilize the strength of materials and has the characteristics of material saving and light dead weight, so that the span capacity of the suspension bridge in various systems of bridges is maximum, and the span can reach more than 1000 meters. The main disadvantage of the suspension bridge is that the suspension bridge has low rigidity, and is easy to generate large deflection and vibration under the action of load, and corresponding measures need to be taken.

At present, a cable-crossing crane is generally adopted for construction of a suspension bridge for erection, however, in some mountain areas with laggard development, the large-scale engineering machinery is difficult to use, and the erection construction is difficult.
