Eccentric load alarm device for 0 # block of prestressed continuous box girder

The utility model provides an eccentric load alarm device for a 0 # block of a prestressed continuous box girder, and belongs to the technical field of engineering prestressed continuous box girder construction. The problems that in a traditional bridge construction project, a prestressed continuous box girder 0 # block cannot monitor the change of the eccentric load in the bridge process in real time, and a conventional monitoring method cannot achieve all-weather and all-directional monitoring are solved. The device comprises an alarm mechanism and a plurality of gravity sensors, the gravity sensors are arranged between a prestressed continuous box girder 0 # block and a pier body, the prestressed continuous box girder 0 # block is arranged above the pier body, and the alarm mechanism is arranged on the top end face of the prestressed continuous box girder 0 # block. And the alarm mechanism comprises a wave-form gravity value display and an over-limit alarm horn. The device is mainly used for prestressed co
