On-line monitoring system for seismic performance of building seismic bracing

Abstract

The invention discloses an on-line monitoring system for seismic performance of a building seismic bracing. The on-line monitoring system comprises a wall body, a first support, a second support and a third support, the first support, the second support and the third support are connected with the wall body, crossed elastic support plates are arranged between the first support and the second support, the bottom of the first support and the bottom of the second support are connected with supporting rods through connecting rods, a supporting plate is arranged between the supporting rods, a fixing frame is arranged on the surface of the supporting plate, and movement amount detecting devices are arranged at the left end and the right end of an elastic supporting plate. The device is provided with a special support structure, so that the support structure is more stable, meanwhile, the detection effect of the bracing is more real-time and accurate, damage to the support in the long-term operation and maintenance process and secondary disasters during earthquakes are reduced, targeted maintenance of managers is facilitated, the labor cost is greatly saved, and an alarm lamp is arranged so that the workers can be visually reminded in real time when the bracing is damaged.

Description

technical field [0001] The invention relates to an on-line monitoring system for the anti-seismic performance of a building anti-seismic support and hanger. Background technique [0002] The function of the anti-seismic support and hanger is to connect the main body of the building structure with various pipelines, equipment and grooves in the building with anti-seismic design, and use the reaction force generated by the earthquake to provide support. Buildings with anti-seismic supports and hangers are less affected by earthquakes, which can effectively reduce damage during long-term operation and maintenance, reduce earthquake damage, prevent secondary disasters, avoid casualties as much as possible, reduce economic losses, and improve the safety of buildings. [0003] A large number of studies have found that the damage of structural components is mostly concentrated in the ceiling system, pipeline system, filling wall damage, etc., and the investigation found that there ...

AI Technical Summary

Problems solved by technology

[0003] A large number of studies have found that the damage of structural components is mostly concentrated in the ceiling system, pipeline system, filling wall damage, etc., and the investigation found that there are two main reasons for the damage of the pipeline system: one is due to the cracking of the pipeline joint or the pipeline is pulled out; the other is the lack of reliable The lateral and longitudinal support system or the suspension of the pipeline, the damage of the support system leads to the fall of the pipeline

After the installation of the anti-seismic support and hanger is completed, once the geological vibration or the wall is damaged, the rivet connection of the support will be loosened or the support will be deformed, which requires manual inspection and replacement, which requires a lot of manpower and material resources for maintenance.
