Problems solved by technology

[0004] In the prior art, the force monitoring of the support mainly relies on the pressure sensing unit. Since the sensing unit is usually fixed to the main body of the support, if the sensing unit needs to be replaced, the entire support needs to be replaced and the operation needs to be stopped. Well-functioning lines, costly and complicated to operate

Abstract

The invention belongs to the technical field of bridge/building support seats, and particularly relates to a pressure-bearing elastomer stress monitoring device of a basin-type support seat. The pressure-bearing elastomer stress monitoring device comprises one or more pressure sensors provided with a limiting mechanism and arranged on the periphery of the outer circle of a basin body, wherein a plurality of through holes for force transmission pins to penetrate through are formed in the side wall of the basin body, one end of each force transmission pin is connected with the corresponding pressure sensor, and the other end of each force transmission pin is connected with a pressure-bearing elastomer in the basin body. According to the invention, the pressure-bearing elastomer stress monitoring device can carry out real-time stress monitoring on the whole life cycle of a bridge support seat, is convenient to assemble and disassemble, can timely maintain and replace an internal sensor, and has the characteristics of simple and compact structure and reasonable design layout.

Description

technical field [0001] The invention belongs to the technical field of bridges / building supports, and in particular relates to a force monitoring device for a pressure-bearing elastic body of a basin-type support. Background technique [0002] Due to its remarkable shock isolation effect and relatively mature technology, the basin rubber bearing has been widely used in bridge engineering construction. In the existing bridge design code system, most of the bridge load and force distribution parameters are calculated based on theoretical assumptions. Due to the lack of effective practical work test methods, the calculation results are not consistent with the actual bearings. There is a certain error in the situation. When the error is too large, it will cause the bridge to work abnormally and form a large safety hazard, or the safety degree design is too large to cause waste of materials. [0003] Therefore, adding real-time monitoring function to the bridge to realize the he...
