Abstract

The invention discloses a highway bridge beam anti-beam-drop limiting device. The highway bridge beam anti-beam-drop limiting device comprises a bridge beam and a bridge abutment, beam foots of the bridge beam are fixedly connected to a suspended beam placing stand of the bridge abutment through a damping support, and are connected with the bridge abutment through two sets of steel strand connecting mechanisms, the portion a certain distance from the bottom of the steel strand connecting mechanism is provided with the other set of the same steel strand connecting mechanism, the two sets of steel strand connecting mechanisms are reversely installed, the surface of the bottom of the right tail end of the bridge beam is provided with several tail parts of which the cross sections are in trapezoidal shapes, a knock-off block is arranged at the top of the bridge abutment, an engagement cavity is formed in the middle of the junction of the knock-off block and the bridge abutment, a PC steel frame is arranged at the bottom of the left end of the bridge beam, and is fixed to the bridge beam through an inner fixing connecting column, and an elastic buffering plate is arranged at the right side face of the PC steel frame.

Description

technical field [0001] The invention relates to the technical field of bridge manufacturing, in particular to an anti-drop beam limiting device for highway bridges. Background technique [0002] A bridge refers to a building built for roads to cross natural or artificial obstacles. It is erected on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. Bridges generally consist of superstructures, substructures and subsidiary structures. The superstructure mainly Refers to the bridge span structure and support system; the substructure includes abutments, piers and foundations; the auxiliary structures refer to the bridge head abutment, conical slope protection, revetment, diversion works, etc. Bridges are divided according to the structural system, including girder bridges, arch bridges, The four basic systems of rigid frame bridge and suspension cable load-bearing often produce relatively large relative displacement between the upper and lower structure...
