Description

Technology Field

[0001] The present invention relates to a trajectory tracking device that records displacement occurring between the superstructure and substructure of a bridge, and a bridge bearing capable of trajectory tracking. Background Technology

[0002] A bridge bearing refers to a device installed between the superstructure and substructure of a bridge to support the load of the superstructure, while simultaneously accommodating expansion, rotational displacement, and movement caused by temperature changes, creep, drying shrinkage, and deflection, and to support and transmit loads, vibrations, and shocks.

[0003] Bridges undergo continuous expansion, contraction, and movement of their superstructures and substructures due to temperature changes, humidity changes, creep, traffic loads, vibrations, earthquakes, and other factors.

[0004] The expansion and movement of bridges are major inspection targets during safety inspections, and measuring devices for measuring bridge displacement are installed and used between the bridge superstructure and substructure or on bridge supports.

[0005] However, conventionally, the three-dimensional movement of the bridge could not be accurately recorded, and the device was complex because a separate device for recording horizontal displacement and a device for recording vertical displacement were installed, and the installation and replacement costs increased due to the inefficient structure.

[0006] Therefore, it was necessary to develop a device and bridge bearing capable of recording horizontal and vertical displacements by a single device and accurately determining the three-dimensional movement of the bridge. Prior art literature
