A spherical force-measuring bearing for bridges and building structures

Abstract

This utility model discloses a spherical force-measuring bearing for bridges and building structures, including an upper bearing plate, a flat sliding plate, a conical pad, a spherical plate, a lower bearing plate, and sensors, with each component arranged sequentially from top to bottom. The upper end of the upper bearing plate is connected to the beam body, and the lower end is connected to the flat sliding plate, which is fixed to the conical pad. The spherical plate has an installation groove in the middle to fix the conical pad, and the sensor is mounted on the outer wall. The lower bearing plate has a sliding groove inside, in which the spherical plate is placed, and the lower bearing plate is connected to the bearing pad or pier top. This bearing acquires force data in real time through sensors and a signal processing system, facilitating monitoring and early warning. The conical pad and the conical surface of the spherical plate cooperate to convert vertical force into radial deformation of the spherical plate, amplifying the strain signal and improving accuracy. The uniform arrangement of multiple sensors reduces errors. It has the functions of bearing, rotation, and force measurement, with a compact structure and convenient installation. The signal processor supports remote transmission and on-site display, meeting the needs of intelligent operation and maintenance and reducing labor costs.
