Horizontal deformation recording device of seismic isolation bearing

Abstract

The invention relates to a horizontal deformation recording device for an isolation bearing. The horizontal deformation recording device comprises an upper support, a lower support, a probe, a recording plate and a digital converter. The top end of the upper support is fixedly connected with an upper end plate or an upper buttress of the isolation bearing and does not horizontally shift relative to the upper end plate or the upper buttress, the lower end of the upper support is connected with the probe and used for driving the probe to move, the bottom end of the probe contacts with the recording plate to form a data acquisition pair, the recording plate is used for recording horizontal movement of the probe relative to the recording plate and further connected to the digital converter, the digital converter is used for converting analog signals transmitted by the recording plate into digital signals, the recording plate is fixed onto the lower support, and the lower support is fixed to a lower end plate or a lower buttress of the isolation bearing and does not horizontally shift relative to the lower end plate or the lower buttress. The horizontal deformation recording device for the isolation bearing can record horizontal deformation of the isolation bearing in real time, and the working performance of the isolation bearing and safety of a building structure are conveniently judged by engineers.

Description

technical field [0001] The invention belongs to the field of earthquake isolation of building structures, in particular to a recording device for recording the horizontal deformation response of an earthquake isolation support under earthquake action. Background technique [0002] Seismic isolation is a technical measure to install flexible seismic isolation bearings at the bottom of the isolated objects, such as buildings, bridges, mechanical equipment, etc., to reduce the transmission of earthquake vibrations to the isolated objects. Compared with the traditional anti-seismic structure, the seismic isolation structure has the following advantages: (1) obviously and effectively reduce the seismic response of the structure; (2) the anti-seismic measures are simple and the mechanical mechanism is simple; (3) the high-intensity area can reduce the housing cost; ( 4) There is generally no need for repairs after an earthquake. At present, seismic isolation technology has mature...

Problems solved by technology

At present, seismic isolation technology has matured, and has begun to be popularized and applied in most high-intensity areas in my country; however, in the current technical field, there is a lack of devices for monitoring and evaluating the working conditions of seismic isolation bearings under earthquake vibrations, and it is impossible to further fully understand the isolation technology. The working performance of the seismic bearing, so as to take appropriate countermeasures for the seismic safety of the isolated object
