Abstract
The invention discloses an intelligent steel strand which comprises a plurality of steel wires and a carbon fiber composite rod. The carbon fiber composite rod is arranged in the center of the steel wires. The steel wires are wound around the outer edge of the carbon fiber composite rod. The carbon fiber composite rod comprises composite carbon fiber and an optical fiber arranged in the composite carbon fiber. The intelligent steel strand has the advantages that the carbon fiber and the optical fiber composite rod replace a center cable located in the center of the steel strand in the traditional process, the stress state of the prestress steel strand is monitored in real time by monitoring changes of a fiber bragg grating, the potential hazards of the steel strand can be found in advance, and safety is improved; real-time monitoring and intelligent management of a whole bridge or a building are facilitated. The intelligent steel strand is simple in structure, convenient to manufacture and suitable for being popularized on a large scale.
Description
Technical field
The present invention relates to prestress wire, particularly be can a kind of intelligent steel strand of Real-Time Monitoring stress.
Background technology
In bridge and railway basic component, widely use the carrier of steel strand wires as concrete component.Every root steel strand wires are made up of many steel wire windings, and in use, every root steel strand wires are all in extended state.Prior art cannot monitor the change of every root steel strand wires tension in use, when wherein steel strand wires are due to alignment error or occur the large stress state of burst, when making its work tension exceed its yield stress, steel strand wires can be in surrender extended state, when deformation values oversteps the extreme limit, the maximum bearing stress of these root steel strand wires sharply diminishes, and occurs fracture.Because wherein steel strand wires are lost the job ability and make other steel strand wires working stress increase, greatly add the risk of overall steel twisted wire fracture, endanger the safety of the buildings such as whole bridge, roadbed.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide one to avoid risk, a kind of intelligent steel strand of Real-Time Monitoring every root steel strand wires stress.
The technical scheme solved the problems of the technologies described above is: a kind of intelligent steel strand, and described intelligent steel strand comprises: many steel wires and a carbon fiber compound bar; Described carbon fiber compound bar is arranged on many steel wire centers, and many steel wire windings are in carbon fiber compound bar outer rim; Described carbon fiber compound bar comprises: carbon fiber reinforce plastic and the optical fiber be arranged in carbon fiber reinforce plastic.
Preferred version is: described Fiber connection is on the optical time domain reflectometer of energy detection fiber grating change.
The advantage that the present invention has and good effect are:
1, the present invention utilizes carbon fiber and optical fiber compound bar to the center cable replacing tradition to be positioned at steel strand wires center, the Real-Time Monitoring of prestress wire stress is realized by the change of monitoring fiber grating, find steel strand wires hidden danger in advance, greatly improve security.
2, the present invention contributes to the Real-Time Monitoring and the intelligent management that realize whole bridge or building.
3, the present invention be applied in concrete with time, owing to being consolidated with concrete, can STRESS VARIATION in indirect reaction concrete work state, find the existence of the defects such as crack in concrete early.
4, structure of the present invention is simple, easy to make, suits large area to popularize.

Fig. 2 is the cross-sectional view of Fig. 1.
" in accompanying drawing, sequence number illustrates "
1: intelligent steel strand; 1a: steel wire; 2: carbon fiber compound bar; 2a: carbon fiber reinforce plastic; 2b: optical fiber; 3: optical time domain reflectometer; 4: wire.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail.
The invention provides a kind of intelligent steel strand 1, described intelligent steel strand 1 comprises: many steel wire 1a and carbon fiber compound bar 2; Described carbon fiber compound bar 2 is arranged on many steel wire 1a centers, and many steel wire 1a are wrapped in carbon fiber compound bar 2 outer rim around carbon fiber compound bar 2 according to a hand of spiral; Described carbon fiber compound bar 2 comprises: carbon fiber reinforce plastic 2a and the optical fiber 2b be arranged in carbon fiber reinforce plastic 2a.
Described optical fiber 2b is connected on the optical time domain reflectometer 3 of energy detection fiber 2b grating change by wire 4.
In particular, as shown in Figure 1 and Figure 2, a carbon fiber compound bar 2 is enclosed in centre by 6 steel wire 1a, carbon fiber compound bar 2 substitutes the position of steel strand wires center cable, the tensile strength of carbon fiber compound bar 2 can reach more than 1800MPa, and the carbon fiber compound bar 2 after making is wrapped in I-beam wheel that diameter is 700mm for subsequent use.
Carbon fiber compound bar 2 of the present invention be by carbon fiber reinforce plastic 2a and optical fiber 2b by mechanical presses, be heating and curing, be closely linked.
In use, intelligent steel strand 1 carries out pre-stress construction as steel strand wires, after pre-stress construction completes, by the many steel wire 1a strip off of intelligent steel strand 1 end, expose carbon fiber compound bar 2, peel mixed carbon fibre 2a again off and expose optical fiber 2b, optical fiber 2b is connected on optical time domain reflectometer 3.
Optical time domain reflectometer 3 is by utilizing emitted light signal, can detect the change of grating in optical fiber 2b, thus reflects STRESS VARIATION suffered by it.Search is that damage has appearred in which steel strand wires.Also the optical fiber 2b of many steel strand wires can be connected on the other hand on a unified real-time watch device, many steel strand wires in concrete component are monitored in real time.When wherein intelligent steel strand 1 stressed excessive cause steel strand wires to be out of shape time, built-in optical fiber 2b along with distortion, real-time watch device just can demonstrate the internal stress situation of change in steel strand wires work, thus scent a hidden danger in advance, increases security.
Claims (2)
