Description

Technical Field

[0001] The present application relates to the technical field of bridge safety measurement equipment, and in particular to a shear deformation measurement device for a highway bridge rubber bearing. Background Art

[0002] During the operation of the bridge, in order to ensure driving safety, it is necessary to conduct regular inspections of the various load-bearing components of the bridge. Among them, the bridge bearings are located between the bridge deck and the piers, directly bearing the bridge deck load and are one of the components that need to be inspected. Bridge bearings are usually made of rubber and are easily affected by bridge deck loads and vehicle vibrations. Shear deformation occurs easily. When inspecting the bridge, the deformation of the rubber bearings needs to be measured.

[0003] The existing announcement number is CN203848793U, and the name is a plate-type rubber bearing shear deformation measuring device, including a triangle plate and an auxiliary rod, the triangle plate is a right-angle triangle plate composed of an acute angle of 35° and an acute angle of 55°, the auxiliary rod is a telescopic auxiliary rod, the auxiliary rod includes a first rod body, a second rod body and a third rod body, wherein the diameter of the third rod body is smaller than the diameter of the second rod body, the diameter of the second rod body is smaller than the diameter of the first rod body, the second rod body is movably arranged inside the first rod body, and the third rod body is movably arranged inside the second rod body. The structure is simple and compact, and it is more convenient to measure higher piers. It is suitable for various on-site requirements, easy to carry and easy to use, and a handrail is vertically arranged at the bottom of the rod body, which can facilitate the operator to hold the rod during measurement, so as to achieve the purpose of accurate measurement and provide more real and accurate digital basis for bridge maintenance.

[0004] With respect to the above-mentioned related technologies, the inventors found that the above-mentioned method of detecting the deformation amount of the rubber bearing measures the deformation amount of the rubber bearing through a triangle plate with a fixed degree. A triangle plate with a single degree cannot accurately measure the deformation amount of the rubber bearing, and the measurement range is single, which affects the measurement range of the deformation amount of the rubber bearing and affects the measurement accuracy of the deformation amount of the rubber bearing.
