Description
Technical field
The utility model relates to bridges in highway engineering field more particularly to a kind of bridge displacement early warning systems.
Background technique
Currently, overwhelming majority in-service medium and small bridges (especially continuous curved box girder bridges) in China's act in various power
(such as: earthquake, car and boat collision) under certain vertically and horizontally displacement can occur, in addition some Static behaviors (such as: expansion joint card
Extremely, temperature action, bias of quiet dynamic load etc.) under can also generate the displacement of any direction, and gradually add up at any time.These occur
The bridge of beam body deviation has seriously threatened the safety of road operation, is highly desirable that it is targetedly repaired and added
Consolidate and carry out the research and development of relevant device, tackle the problem at its root.
For the research of the damping device of bridge earthquake resistance limit, there are four types of the methods that the country usually uses at present: (1) using
The method of damp type support progress displacement constraint.The shortcomings that this method, is that initial stage binding effect is preferable, but subsequent stages
Section is such as replaced not in time since the problems such as corrosion of support itself, deformation, failure causes constraint to be failed, may be to the peace of bridge
It entirely uses and causes a hidden trouble, and the replacement of support construction is pretty troublesome.(2) rigid or semi-rigid (be provided with bullet in the setting of beam body two sides
Property padding) baffle anti-bias limit method.This method be mainly the bar planting in beam bottom or bent cap, by bar planting be arranged rigidity or
Semi-rigid baffle, the blocking by force by baffle prevent beam body from shifting.The above method is primarily present following unfavorable factor: its
One, limit method is excessively strong, belongs to the limit for stopping formula by force, this not only may cause biggish beam body internal stress, may be used also
It can cause the damage of beam body bottom, pier top or bent cap top；Second, this mode spacing equipment intensity is lower, generally it is only applicable to

It is standby.Though this method improves the shortcomings that pressure limit, has certain flexibility, the spring not restored after compression can tied
The internal force that can not be discharged is formed in structure, this internal force is a security risk always, threatens the safety of beam body or stub, and mesh
The equipment of preceding research and development can only realize the limit in a direction, cannot achieve any direction limit.(4) it is installed in beam body a direction
Viscous damper is oriented, although this method can discharge internal force after limit, orientation limit is still only used for, can not achieve and appoint
It anticipates direction, once there are other directions or unoriented displacement (such as torsional displacement), equipment are easy to destroy.Above-mentioned damping
Equipment has that a common defect is that Internet of Things is not implemented namely equipment is an independent individual, does not have with monitoring
The ability of department's exchange, is unfavorable for the real time monitoring of administrative staff in this way, is also unfavorable for the safe operation of bridge.
