Description
Technical Field
The utility model belongs to the technical field of bridge beam supports's technique and specifically relates to indicate bridge beam supports changes device.
Background
The bridge support is an important structural component for connecting an upper structure and a lower structure of a bridge, is positioned between the bridge and the pad stone, can reliably transfer load and deformation borne by the upper structure of the bridge to the lower structure of the bridge, and is an important force transfer device of the bridge.
Bridge supports are susceptible to damage after being used for a period of time, requiring periodic inspection of the supports and replacement of the damaged supports. When the support is replaced, a hydraulic jack is usually used for supporting the bridge, a constructor takes out the damaged support, places a new support in a preset position and fixes the new support.
But when the device is applied, the symmetry of jacks at two sides of the bent cap and the synchronous jacking process are strictly required, so that the eccentric compression or local pressure bearing condition is prevented, and the local instability condition of the saddle-shaped support is avoided.
