Abstract

The invention relates to the field of bridge construction, and specifically discloses a reset type bridge expansion joint device, which comprises symmetrically arranged expansion joint channel steel, two sets of connection cavities are opened on the opposite surfaces of the expansion joint channel steel, and the longitudinal section of the connection cavity is elliptical. The connecting cavity runs through the expansion joint channel along the length direction of the expansion joint channel; the connecting cavity is placed with a coaxial cylindrical steel, and the longitudinal section of the cylindrical steel is circular; the horizontally adjacent connecting cavities A number of evenly distributed buffer rods are arranged between them. The buffer rod includes a moving rod and a hollow fixed rod. The movable end of the moving rod is slidably connected in the fixed rod, and a buffer spring is arranged between the moving rod and the fixed rod. , the end of the connection cavity is provided with a connection groove parallel to the expansion slot steel, and the width of the connection groove is smaller than the diameter of the cylindrical steel; the fixed ends of the moving rod and the fixed rod are fixedly connected to the corresponding cylindrical steel; this The invention aims to solve the problem that the existing bridge expansion joint device cannot assist the beam body to restore deformation.

Description

technical field [0001] The invention relates to the technical field of bridge construction, and specifically discloses a reset type bridge expansion joint device. Background technique [0002] In order to meet the requirements of bridge deck deformation, expansion joints are usually set between two beam ends, between beam ends and bridge abutments, or at the hinged position of the bridge. The expansion joints are required to be free in both directions parallel to and perpendicular to the bridge axis. Retractable, firm and reliable. The main structure of the traditional expansion joint device is mainly composed of two pieces of hot-rolled integrally formed special-shaped steel and anchoring steel bars for welding and fixing. Deformation reset and channel steel reset basically rely on the beam body itself to restore the deformation, which cannot help the beam body to restore the deformation; however, during the long-term use of the bridge, the vehicle continuously vibrates th...
