Abstract

A vertical force-measuring hyperboloid spherical shock-absorbing support, which is provided with an upper seat plate, a middle seat plate, a lower seat plate and a base plate in sequence from top to bottom, wherein the middle seat plate and the lower seat plate are connected by a columnar convex The platform and the columnar groove are positioned and installed. The side of the middle seat plate is a circumferential slope. The force measuring device used to measure the vertical force includes a ring-shaped force-measuring block and a data acquisition module. The outer surface of the force measuring block is provided with a mounting groove for installing a resistance strain element, and the resistance strain element connected with the data acquisition module is installed in the installation groove. The invention monitors the vertical pressure above the support by a corresponding force measuring device, solves the problem of vertical force measurement of the shock-absorbing and isolating support, and provides technical support for bridge monitoring.

Description

technical field [0001] The invention belongs to the technical field of bridge structures or buildings, and relates to a hyperboloid spherical shock-absorbing and isolating bearing with the function of vertical force measurement. Background technique [0002] Now in China's transportation engineering construction, new high-speed railways and expressway bridges account for an increasing proportion. In order to ensure the construction and operation safety of a large number of bridges and super-large bridges with complex structures, there is an urgent need for a reliable and popular modern monitoring and early warning means. As an important part of the bridge system, bridge accessories play an important role in ensuring the normal function of the bridge. The use status of bridge accessories has an important impact on the operation of bridges, and effective monitoring of the working status of bridge accessories can also evaluate the working status of bridges. [0003] The girde...
