Description
Technical field
The invention belongs to bridge structure technical field, more particularly to intelligent aluminium alloy tendon concrete structure and its make and apply
Work method.
Background technology
At present in Bridges in Our Country structure construction procedure, reinforced concrete structure is adopted mainly, inside concrete, adopt steel
Muscle undertakes load as skeleton, together with concrete, and structural key position and stress are concerned about that the reinforcing steel bar bear situation at position is failed to understand
Really, reinforcement stresses is unable to real-time online health monitoring, and precision is not high, and there are the following problems：
(1) there is corrosion in reinforcing bar, especially coastal area, have a strong impact on safety and the durability of bridge.At present
Many bridges are all work with cracking, the reinforcing bar and air contact in concrete, and under environmental activity, easy corrosion, can not only lead
Reinforcing bar effective cross-section is caused to weaken, the development in swollen aggravation crack of also further becoming rusty has a strong impact on safety and the durability of bridge,
This phenomenon is especially apparent in coastal area, additionally, building in the water of coastal area, such as bridge pier, abutment, basis etc.,
In the presence of sea water, it is easier to cause steel bar corrosion.
(2) Steel Bars in Concrete Structure weight is larger, lifts and transports inconvenience, limit beams of concrete in work progress
Span ability.The bearing capacity of beams of concrete has greatly for overcoming the deadweight of concrete and reinforcing bar, this big across
Become apparent from degree concrete-bridge, high strengthening, lightness are developing direction of following bridge, a kind of new lightweight is high
Strong material contributes to the lifting for realizing load carrying capacity of bridge and span ability.
(3) in concrete component, the stress of reinforcing bar is indefinite, and health status are difficult to monitor.The bridge for occurring in the last few years collapses
Collapse accident, cause huge life and property loss and severe social influence, people are gradually caused to bridge safty
Concern, bridge health monitoring is the important development direction of following bridge, and the round-the-clock real time on-line monitoring of bridge member and transmission are
One important feature, for the crucial force part of structure, such as at girder and bridge pier key position, bracket etc., existing mixed
In solidifying soil, reinforcing bar cannot accomplish real-time monitoring and early warning.
Content of the invention
The technical problem to be solved in the present invention be to provide a kind of high-strength light, corrosion-resistant, improve xoncrete structure durable
Property, can real-time monitoring xoncrete structure stress and safety and Health early warning, strain measurement high precision, the intelligent aluminum of low cost close
Golden tendon concrete structure and its making and construction method.
The present invention employs the following technical solutions solution above-mentioned technical problem：
Intelligent aluminium alloy tendon concrete structure, the skeleton in the xoncrete structure are constituted for aluminium alloy muscle, and the aluminum is closed
Golden muscle is containing intelligent aluminium alloy muscle.
The intelligent aluminium alloy muscle is to slot on aluminium alloy, places fiber-optic grating sensor, groove inwall and optical fiber in groove
Grating sensor is coated with protective layer.
The protective layer is epoxy resin or zinc-plated.
The skeleton be the colligation of aluminium alloy muscle into aluminium alloy muscle cage.
The making of described intelligent aluminium alloy tendon concrete structure and construction method, it is characterised in that：Processing step is as follows：
(1) formwork supporting plate：Design size and the processing and installation that require to carry out template according to structure；
(2) tied framework：The force analysis of mechanical characteristic, structure according to aluminium alloy and design carry out arrangement of reinforcement, make intelligence
Energy aluminium alloy muscle, the construction drawing further according to design carry out the colligation of skeleton, and wherein intelligent aluminium alloy muscle reserves fiber grating biography
The wiring of sensor, and collect；The manufacture method of the intelligent aluminium alloy muscle is：
1. slot：Longitudinal grooved on aluminium alloy；
2. fiber grating is installed：1. the groove inwall opened up in step coats epoxy resin protective layer or zinc-plated protective layer, so
Afterwards fiber-optic grating sensor is placed in groove；
3. coating epoxy resin protective layer or zinc-plated protective layer cover fiber-optic grating sensor again；
(3) casting concrete：Lifting skeleton enters in template, and casting concrete finally carries out the maintenance of concrete.
The thickness of the epoxy resin protective layer or zinc-plated protective layer for covering fiber-optic grating sensor is 1mm to 2mm.
The beneficial effects of the present invention is：
(1) xoncrete structure of the invention is all using aluminium alloy muscle or aluminium alloy muscle and intelligent aluminium alloy muscle group skeletonization
Frame, compared with regular reinforcement, good endurance especially can be good at applying in coastal area and submerged structure structure, no
Extra preservative treatment is needed, the durability of xoncrete structure can be significantly improved, a large amount of reinforcing maintenance costs are saved；
(2) concrete structure quality of the invention is lighter, and intensity is high, and model is more, and reinforcing bar density is 7850kg/m3, aluminum conjunction
Golden density is 2650kg/m3, aluminium alloy density is the 1/3 of reinforcing bar density, and under same volume, quality is the 1/3 of steel, colligation,
Lifting and transport more convenient, extra rust cleaning is not needed before construction, is used on bridge, to bridge effect of weight less, and
The bearing capacity of bridge can be dramatically increased.Aluminium alloy yield strength is suitable with reinforcement yielding intensity, be attained by 300MPa with
On, and the species and model of aluminium alloy are more, the aluminium alloy of more high intensity is also constantly being developed；
(3) xoncrete structure of the invention by intelligence aluminium alloy muscle can real-time online carry out inside concrete aluminium alloy
The Internal Force Monitoring of muscle and early warning, realize the safety and Health monitoring of bridge key force part, and the wiring of measuring point are simple；
(4) intelligent aluminium alloy muscle of the invention can be used not only for, inside xoncrete structure, can be also used for xoncrete structure
Outside, can be not only used for the construction of new bridge, can be also used in the reinforcing of old bridge, not only can all apply in full-bridge
Intelligent aluminium alloy muscle, only can also apply in crucial force part, and the scope of application is wider；
(5) aluminium alloy muscle in intelligent aluminium alloy tendon concrete structure of the invention is easy to process and colligation, with ordinary steel
Muscle is more easily than storage, and does not need extra processing of rust removing before casting concrete, cost-effective；
(6) fiber grating is combined with aluminium alloy, can play respective advantage, is realized to bridge capacity and bridge full longevity
Life health monitoring.Common embedded strain gauge measuring strain precision is 1 ε μ, and fiber grating strain certainty of measurement can reach 0.1 ε μ,
Durability, stability and anti-interference be better than common embedded strain gauge, and common embedded strain gauge is easier to damage, no
It is beneficial to long term monitoring.
