Description
Technical field
The utility model belongs to reinforced concrete work field, and in particular to a kind of carbon cloth reinforced concrete
Structures.
Background technology
Due to the particularity of Beibu Bay, guangxi area affiliated area, engineering structure system (including Oversea bridge, coastal build
Build, harbour sea wall etc.) erosion such as typhoon, storm tide, sea salt, fouling organism is faced for a long time, to coastal engineering safety of structure shadow
Sound is very big, the irrationality used plus people engineering structure, often makes engineering structure Local Damaged, crack occur causes
Steel bar corrosion, reduces the service life of reinforced concrete structure, and the result of long-term corrosion will result in reinforcing bar fracture and make knot
Structure destroys.In general, reinforced concrete work once destroys, and caused Loss of Life and property will be huge
, it is even more far-reaching and difficult to the appraisal to national economy and the influence of society.
At present, reinforced concrete structures typically carry out repairing and reinforcing using carbon fibre reinforced plastic method for strengthening (CFRP),
Carbon cloth is pasted on concrete surface using resinae adhesive, to improve the bearing capacity of component, so as to reach to structure
The purpose of part reinforcing.CFRP Sheet Strengthening Method be according to structural elements Calculation and Analysis of Force result and stress characteristic, using with
Carbon fiber is pasted on the outside corresponding site of concrete component (damaged structure) that intensity is unsatisfactory for force request by set resin, with up to
Meet a kind of method for reinforcing of requirement for bearing capacity to component.Its reinforcement principle is to utilize the shear strength of its auxiliary resin will
The load of concrete component load-bearing passes to carbon fiber, makes rear sticking carbon fiber and the common bearing load of former reinforced concrete member
Active force.Experiment shows：In Carbon Fiber Concrete Composites structure, the stress of two kinds of materials mainly passes through interface agglutination layer
Effect is bonded to transmit, the destruction of component generally begins at the destruction of glued layer.With being continuously increased for load, bonding interface stress
Branch and peak gradually change, inside concrete tension also constantly increases, when load increases to close to bonding
During the load of intensity, the bonding interface at concrete separation internally is by by the compound work of interface normal stress and in-plane stress
With in the presence of this combined stress, the concrete that carbon cloth adhesive tape shallow-layer is peeled off since the position, works as load
When reaching failing load, because the effective area of bonding is reduced, disposable stripping damage just occurs at interface, that is, destroying is
The brittle break instantaneously occurred.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of carbon cloth reinforced concrete structures, makes carbon
Fiber cloth firmly can be bonded on works, it is not easy to occurred being broken and peeled off.
Technical scheme provided by the utility model is carbon cloth reinforced concrete structures, including concrete structures
Basic unit and carbon fiber layer, the concrete structures basic unit treats to be equipped with the one layer of lightweight for including steel wire coagulation on reinforcing face
Native repair layer；The composite bed that the carbon fiber layer is made up of the carbon cloth and the PVC that is coated of infiltration epoxy resin
Shape structure；The carbon fiber layer is pasted onto in lightweight concrete repair layer by adhesive；The structures also include two blocks of steel
Plate, two blocks of steel plates are arranged on the both ends of carbon fiber layer, and by sequentially passing through steel plate, carbon fiber layer, repair layer and basic unit
Be bolted on structures.
One layer of lightweight concrete repair layer for being embedded with steel wire of laying on reinforcing face is treated in concrete structures basic unit,
The consolidation effect of Local Damaged structure can be improved, the attachment force of carbon cloth and structures basic unit can be greatly improved again,
Avoid because concrete base layer finish not enough causes carbon fibre cloth layer not to be bonded in effectively in structures basic unit.
The straticulate structure that carbon fiber layer is made up of the carbon cloth and the PVC that is coated of infiltration epoxy resin；
Its preparation method is：By carbon cloth infiltration in the epoxy, take out, the carbon fiber cloth bag of epoxy resin will be infiltrated with PVC
Cover, hot pressing so that PVC is combined into one with carbon cloth, forms straticulate structure.Because PVC melting temperature is high
In the glass transition temperature of epoxy resin, control hot pressing temperature PVC melting temperature and glass epoxy inversion temperature it
Between so that PVC and carbon fiber consolidation are integral.Toughness, wearability and the skid resistance of carbon fiber layer after Combined Processing significantly carry
Height, and then the adherence force of carbon fibre cloth layer and structures can be improved, prevent the landing of carbon fibre cloth layer.
Stainless steel plate is set at the both ends of carbon fiber layer, carbon cloth can be fixedly secured in structures basic unit so that
Carbon cloth is bonding with structures basic unit more firm, effectively prevents carbon cloth from coming off, to improve the use longevity of structures
Life.
The structures also include anticorrosive coat；Coated on carbon fiber layer, two pieces of stainless steel plates are set the waterproof layer
Put at the both ends of waterproof layer, and consolidated by sequentially passing through stainless steel plate, waterproof layer, carbon fiber layer, repair layer and the bolt of basic unit
It is scheduled on structures.One layer of waterproof layer is coated on carbon cloth surface, can effectively reduce carbon cloth by external environment condition
Influence, extend service life of structure.
The waterproof layer is polyurethane water-proof layer.The thickness of the polyurethane water-proof layer is 1~2mm.
The structures also include anticorrosion mortar layer；For the anticorrosion mortar layer coated on waterproof layer, described two pieces stainless
Steel plate is arranged on the both ends of waterproof layer, and sequentially passes through stainless steel plate, anticorrosion mortar layer, waterproof layer, carbon by stainless steel bolt
Fibrous layer, repair layer and basic unit are bolted on structures.One layer of screed is coated on the outer surface of waterproof layer, can be entered
One step protects carbon cloth not corroded by external environment, avoids carbon cloth from coming off, to improve the service life of structures.
The thickness of the screed is 2~5mm.
Compared with prior art, concrete structures of the present utility model are simple in construction, and fastening effect is good, can effectively prevent
Carbon cloth comes off from structures basic unit, so as to substantially prolongs the service life of concrete structures.
