Abstract

The invention relates to the field of bridge construction, and specifically discloses a prefabricated bridge anti-drop beam structure, which is characterized in that: it includes a bridge pier fixedly connected to the ground, and the top of the bridge pier is provided with a coaxial circular frustum-shaped connecting seat, and the top of the connecting seat is fixedly connected There is a positioning shaft with a coaxial line; the top of the positioning shaft is threaded with a ring-shaped mounting seat, and the mounting seat and the bridge pier are detachably connected by bolts; the bottom of the mounting seat is provided with a groove for the coaxial line; the circular array is measured around the mounting seat A number of chutes are distributed, and fixed columns are slidably connected in the chutes, and the fixed columns extend into the groove, and a return spring is arranged between the fixed column and the mounting seat; a beam body symmetrical to the mounting seat is arranged on the top of the pier, and the beam body The thickness is the same as that of the connecting mounting seat, and both ends of the beam body are provided with semicircular openings connected with the mounting seat, and a semicircular limiting groove is provided at the opening; The installation process of the device is cumbersome.

Description

technical field [0001] The invention relates to the technical field of bridge construction, and specifically discloses an assembled bridge anti-drop beam structure. Background technique [0002] The prefabricated bridge has reliable quality, intelligent steel bar processing, factory-like component prefabrication, and standardized construction procedures. High-precision positioning ensures the inherent quality of bridge prefabricated components. One of the main advantages of prefabricated bridges is that they are built quickly and have little interference with surrounding traffic. While carrying out pile foundation construction, it is also possible to prefabricate pier columns, bridge abutments and beam slabs, and install them while constructing. Make full use of the time period when the traffic interference is small at night, block one or two lanes, and then the assembly of bridge components can be carried out. The stability of the connection between the girder and the pi...
