Description
Technical field
The utility model is related to reinforcing pull rod tension measurement and its structural safety monitoring field, more particularly to a kind of intelligent steel
Pull rod shaft pin assembly.
Background technology
The change of reinforcing pull rod pulling force is to weigh the important symbol whether reinforcing pull rod structure is in normal condition.Reinforcing pull rod is one
Internal high order redundant structure is planted, the linear and internal force of reinforcing pull rod can be made to reach perfect condition by adjusting reinforcing pull rod pulling force.
But, if the actual suffered pulling force of reinforcing pull rod, which deviate from it, designs pulling force, this deviation can not only make to produce partially between reinforcing pull rod
Carry (unbalance loading is to cause one of the reason for reinforcing pull rod is broken), and girder can be made to produce moment of flexure.By existing to reinforcing pull rod pulling force
Line is monitored, and can not only obtain the dynamic change trend of reinforcing pull rod pulling force, can also be the technology status overall assessment of reinforcing pull rod
Foundation is provided.
The method of traditional reinforcing pull rod tension measurement mainly has stickup strain sheet mode to carry out stress test, but because resistance should
Become piece Shortcomings in terms of barbola work and long-time stability, tend to belong to disposable, be only applicable to detection class
Scape；In addition, in structure installation, sensor is typically affixed directly on the pull bar body of rod by traditional approach, this mounting means category
Installed in addition type, external, the protective of appearance and sensor to the body of rod is relatively low, in the work of engineering construction bad environments
Under condition, the damage that measurement apparatus is highly prone to external force causes failure；Secondly, in the information trackability function side of dispatching from the factory of reinforcing pull rod
Face, is retained by units such as manufactory, designing institutees more than the information dispatched from the factory due to reinforcing pull rod, and its own does not enter row information
Storage, so as to cause its own product information to review.
The content of the invention
In order to solve above-mentioned the deficiencies in the prior art, it is built-in that the purpose of this utility model is to provide a kind of measurement part,
Long-time stability are good, and information of dispatching from the factory can be stored, retrospective intelligent reinforcing pull rod pivot pin device.
Technical problem to be solved in the utility model is achieved by the following technical programs：A kind of intelligent reinforcing pull rod axle
Pin assembly, including reinforcing pull rod pivot pin body, stress induction device, memory, sensor mounting groove, mechanical hole A, mechanical hole B, its
It is characterised by：The reinforcing pull rod pivot pin body end face be provided with sensor mounting groove, the sensor mounting groove be provided with mechanical hole A,
Mechanical hole B, the stress induction device is embedded to be arranged between mechanical hole A and mechanical hole B.
Further, the stress induction device is type vibration wire strain gauge.
Further, the memory be monobus eeprom memory, its model DS2431, capacity is 1Kbit, is adopted
With two-wire system communication mode, the information such as the date of production, production batch number, size can be stored.
Further, the sensor mounting groove length direction is consistent with reinforcing pull rod pivot pin stress F directions.
Further, the sensor mounting groove size is the long 50mm* depth 10mm of width 10mm*.
Further, the mechanical hole A and mechanical hole B is M4 screw holes.
Further, the mechanical hole A and mechanical hole B spacing are 40mm.
The utility model has the advantages that：
The utility model provides a kind of intelligent reinforcing pull rod for designing intelligent apparatus and reinforcing pull rod pivot pin apparatus integration
Pivot pin device, i.e., by the embedded design of intelligent apparatus, be installed within reinforcing pull rod pivot pin device, and do not influenceing reinforcing pull rod pivot pin
On the premise of device self structure and size, realize reinforcing pull rod pivot pin measurement part and use and dispatch from the factory steadily in the long term the depositing of information
Storage；It has the features such as simple in construction, the easy for installation, long-time stability of manufacture are good, information tracing is strong.
