Description
Technical field
The utility model is related to a kind of suspension cable structure with warning function, belongs to the technologies such as bridge, building structure neck
Domain.
Background technology
The parallel steel wire suspension cable being made up of steel wire, is widely used in the fields such as bridge, building already, for example as
Suspension cable in cable-stayed bridge, or the suspension rod in arch bridge.The major accident that structure is damaged however, suspension cable breaks suddenly, does not have but always
Have and prevent.
By taking the suspension cable in cable-stayed bridge as an example, the disrumpent feelings statistical life of suspension cable is 3-16 so far, is rarely exceeded 20 years.
Though improving to some extent in recent years, it can not still look to it identical with the service life of structure；Secondly as its load and environmental activity with
Machine, the rupture life of bridge stay cable is uncertainty, when disrumpent feelings is not aware that.
At present, although the health detection and diagnostic techniques using life prediction as core are generally employed to suspension cable, and
The safeguard of " 3 years one detect, change for 10 years one ", but due to the load randomness acted on and the limitation detected, from essence
On say, such detection and change measure, it is impossible to exclude the danger that suspension cable breaks suddenly.Due to suspension cable rationally, economical change
Time can not be determined, therefore taken general bridge " doubt to break and just change " more, be changed in batches once changing, or even full-bridge is changed, and is wasted
Resource.If judgement is inaccurate, suspension cable occurs to break suddenly, and it is costly that the reparation and suspension cable that bridge is damaged are changed.
Therefore in the urgent need to a kind of suspension cable structure with warning function, it can warn in advance, to change.
The content of the invention
The purpose of this utility model is that solve above-mentioned the deficiencies in the prior art and problem has there is provided one kind
The suspension cable of warning function.
A kind of suspension cable structure with warning function that the utility model is provided, including steel tendon, cladding steel tendon
High density polyethylene (HDPE), the anchorage and warning circuit at two ends, it is characterised in that：The outermost layer of steel tendon has special in the suspension cable
Steel wire, the middle part of special steel wire is fluted, and special steel wire is connected with power supply, alarm with wire, constitutes warning circuit,
Suspension cable during one's term of military service, when the special steel wire in suspension cable reaches that fatigue life is disrumpent feelings in advance, send out by circuit breaker, alarm
Go out alarm.In conventional suspension cable during one's term of military service, due to the effect of external environment condition and load, fatigue life low special steel wire prior to
Ordinary steel wire reaches service life, and steel wire is mostly disrumpent feelings since outer ring, therefore special steel wire is arranged in into outer layer.Oblique
During one's term of military service, special steel wire can occur disrumpent feelings drag-line in advance, and circuit breaker, alarm sends alarm, you can change oblique immediately
Drag-line, it is to avoid occur the phenomenon that bridge breaks suddenly.
Further, groove is circular arc on the longitudinal section of excessively special steel wire axis, and groove curved surface is the circular arc line
Rotate a circle what is obtained around the axis of special steel wire, depth is 0.5 millimeter.The fatigue life of special steel wire is slightly below ordinary steel
Silk, it is ensured that alarm is sent after early warning, has certain time to change suspension cable, meanwhile, ordinary steel wire is obtained also close to its fatigue life
To using to greatest extent, it is to avoid waste of material.
Further, special passed through in special steel wire at anchorage has insulation measures, uses special steel wire in one end of suspension cable
Wire is connected, and special steel wire is connected by the other end with power supply, alarm with wire, forms path.Insulation processing be in order to
Prevent the leakage of current in special steel wire, it is ensured that warning circuit normal work.
Further, there is the different steel wire of three Gents in every skew cables, be uniformly distributed in 3 angles of the hexagon of steel tendon
Portion, wherein the different steel wire of two Gents is first in parallel, then connects with the different steel wire of another Gent, saves wire, convenient operation.
In addition, the material of special steel wire and ordinary steel wire can be stainless steel, corrosion can be prevented, reduction is disrumpent feelings, causes
Unnecessary waste.
Compared with prior art, the utility model has the advantages that：The fracture more leading than ordinary steel wire of special steel wire,
Warning circuit open circuit, alarm sends early warning, it is to avoid occurs suspension cable and breaks suddenly, and the phenomenon of bridge damage improves the peace of structure
Quan Xing；Alarm is sent after early warning, has certain time to change suspension cable, and ordinary steel wire is obtained also close to its fatigue life
Use to greatest extent, it is to avoid waste of material；The utility model implements simple to operate, does not change conventional parallel steel wire stay cable
Manufacture craft, increases seldom expense, has broad application prospects.
