Abstract
The invention discloses a device for mounting or dismounting a longitudinal beam in the construction of a beam-column type support, which comprises a lifting mechanism and a rolling mechanism, wherein the lifting mechanism and the rolling mechanism are connected through a screw and a bolt and span a distribution beam. The lifting mechanism is lifted up and down through the adjusting bolt, when the upper surface of the lifting mechanism is higher than the upper surface of the distribution beam, the longitudinal beam is erected, and the longitudinal beam is dragged along the direction of the distribution beam to move. When the upper surface of the lifting mechanism is lower than the upper surface of the distribution beam, the longitudinal beam falls on the distribution beam. The device can be used when dismantling the longitudinal beam after the road-crossing bridge support cast-in-place construction is completed, and the longitudinal beam can be conveniently and quickly moved out from the lower part of a newly-built bridge body. The device has simple structure and can be repeatedly used.
