Intelligent lead core rubber stand

Abstract

The invention relates to an intelligent lead core rubber stand which comprises a rubber stand body and an intelligent sensing system. The rubber stand body comprises an upper connecting plate, a lowerconnecting plate, an upper inner sealing steel plate, a lower inner sealing steel plate, rubber pieces, reinforcing steel plates, an outer rubber layer and a lead core. The rubber pieces and the reinforcing steel plates are alternately arranged layer by layer. The intelligent sensing system comprises a first intelligent material integrally formed together with the lead core, a second intelligentmaterial integrally formed together with the outer rubber layer, and a third intelligent material integrally formed together with the reinforcing steel plates. The first intelligent material, the second intelligent material and the third intelligent material are all connected with a data collecting system. The data collecting system is connected with a data transmitting system. The data transmitting system is connected with a data processing and estimating system. By means of the structure, the intelligent lead core rubber stand has the advantages that the stress state and physical state of the stand in the use process can be monitored in real time and the health conditions of the stand can be conveniently and accurately obtained.

Description

technical field [0001] The invention belongs to the technical field of seismic isolation of civil engineering structures, and in particular relates to an intelligent lead rubber bearing. Background technique [0002] The support is an important node component used to connect the upper structure (such as the main body of the building, etc.) and the lower structure (such as the foundation, etc.) in the building structure and bridge structure. The constraints should be as small as possible, and it should be easy to install, maintain and repair. [0003] Existing actual earthquake damage shows that the failure of nodal supports is one of the most common failure forms that lead to the failure of building structures or superstructures of bridge structures. At the same time, during the daily use of the structure, structural damage and collapse events caused by the quality problems of the bearing itself also occur from time to time. Once the support as an important node in the str...

Problems solved by technology

Therefore, the existing sensors can only be installed on the surface of the stiffened steel plate or the lead core, but cannot be installed inside the stiffened steel plate or the lead core, and cannot detect the data of the key stress-bearing parts of the support, and the results are very inaccurate; and if The sensor is installed on the surface of the stiffened steel plate, and the sensor is easily damaged during the pre-pressing process of the stiffened steel plate and the rubber sheet, so the effect is not ideal
