Description
Technical field
The utility model belongs to civil engineering and internet of things field, in particular to a kind of intelligent functional steel twists
Line anchorage.
Background technique
The stress and deformation that monitor bridge are the important means of bridge health monitoring, risk assessment, are obtained more next
More attention, achieves significant progress in recent years.In terms of the ess-strain monitoring of Medium and small span pre-stressed bridge,
Hand-held deformeter and contactless video measuring instrument etc. are widely applied.
But this several quasi-instrument is only capable of measuring the apparent strain of bridge structure, therefore also lacking one kind on the market at present can be with
Facilitate the stress of monitoring bridge internal structure and the practical monitoring means of deformation condition.
Utility model content
For above-mentioned many defects, the present inventor is paying sufficient creation by a large amount of further investigation
Property labour after, so as to complete the utility model.
Specifically, the technical problem to be solved by the utility model is to a kind of intelligent multi-functional steel strand anchorage, both
The intelligent multi-functional prestressed anchor of pre-stressed bridge stress can be monitored in real time again with anchoring prestress steel strand wires.
The utility model basic principle: a kind of intelligent multi-functional steel strand anchorage, by anchor ring outer rim close to anchor plate
The foil gauge that one end is uniformly arranged, foil gauge are connect with (FBG) demodulator, and foil gauge can be with the strain outside real-time perception anchor ring, by anchor
The strain information of ring is converted into voltage signal, and then voltage signal is reduced into digital signal by (FBG) demodulator, whole eventually by receiving
The finite element model at end imports digital signal, analysis, to realize to the real-time monitoring of prestress wire anchor force, long-range
Monitoring and assessment.
The technical solution of the utility model are as follows: a kind of intelligent multi-functional steel strand anchorage, including anchor ring, foil gauge, solution
It adjusts instrument, receive terminal, anchor plate, the anchor ring is fixed at the center of anchor plate, and the anchor ring outer rim is close to anchor plate one
End is evenly arranged with several foil gauges, and the foil gauge is connect by data line with (FBG) demodulator, and the (FBG) demodulator passes through number
According to line and receive terminal.Anchor ring outer rim reaches the maximum anchor force of presstressed reinforcing steel, the position arrangement of monitoring close to anchor plate one end
In anchor ring outer rim close to anchor plate one end.
Preferably, the (FBG) demodulator is connect by data line with wireless signal transmitter, the wireless signal transmitting
Device is connect with terminal wireless is received.Wireless signal transmitter is added in entire steel strand anchorage system, it can be remotely to steel strand wires
Anchor tool system carries out real-time monitoring.
Preferably, the anchor ring outer rim is evenly distributed with 4 foil gauges close to anchor plate one end.The foil gauge of reasonable Arrangement can be more
The strain information of good acquisition anchor ring.
The utility model has the following beneficial effects: a kind of intelligent multi-functional steel strand anchorage, compact-sized, it is low in cost,
It is convenient to construct, and not only with anchoring prestress steel strand wires but also the intelligent multi-functional of pre-stressed bridge stress can be monitored in real time
Prestressed anchor.
Detailed description of the invention

In figure, 1- anchor ring, 2- foil gauge, 3- (FBG) demodulator, 4- reception terminal, 5- wireless signal transmitter, 6- anchor plate.
Specific embodiment
Specific embodiment of the present utility model are as follows: as shown in Figure 1, a kind of intelligent multi-functional steel strand anchorage, including
Anchor ring 1, foil gauge 2, receive terminal 4 at (FBG) demodulator 3, and anchor plate 6, the anchor ring 1 is fixed at the center of anchor plate 6, described
1 outer rim of anchor ring is evenly arranged with several foil gauges 2 close to 6 one end of anchor plate, and the foil gauge 2 passes through data line and demodulation
Instrument 3 connects, and the (FBG) demodulator 3 is by data line and receives terminal 4.1 outer rim of anchor ring reaches presstressed reinforcing steel close to 6 one end of anchor plate
Maximum anchor force, the position of monitoring is arranged in 1 outer rim of anchor ring close to 6 one end of anchor plate.
Specifically, as shown in Figure 1 and Figure 2, the (FBG) demodulator 3 is connect by data line with wireless signal transmitter 5,
The wireless signal transmitter 5 is wirelessly connected with terminal 4 is received.Wireless signal transmitter is added in entire steel strand anchorage system
5, real-time monitoring remotely can be carried out to steel strand anchorage system.
Specifically, as shown in Figure 1,1 outer rim of the anchor ring is evenly distributed with 4 foil gauges 2 close to 6 one end of anchor plate.Reasonable Arrangement
Foil gauge 2 can preferably acquire the strain information of anchor ring 1.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
