Description
Technical field
The invention belongs to carbon fiber recovery technique fields, relate generally to carbon fiber and repair underwater steel construction more particularly to one
The method of the underwater steel component carbon fiber maintenance and reinforcement of kind.
Background technique
Carbon fiber is resin system by a certain percentage and by a kind of composite material made of certain processing technology, is had
The advantages that high-strength light, durability be good, waterproof anti-corrosion, simple construction technology.Development and application and binder with carbon fiber
Performance is continuously improved, advanced restorative procedure of the carbon fiber repairing technique as a kind of high efficiency, low cost, in building work
Very big attention has been obtained in journey and is conducted extensive research and is applied.
Traditional underwater steel construction recovery technique mainly has welding, rivets or be spirally connected, these restorative procedures are in addition to operation
Outside the disadvantages of difficulty is big, and reparation is long in time limit, less economical, stress concentration and residual stress of structure etc. are also caused in various degree
Problem.At present carbon fibre reinforced composite repair concrete structure technique it is mature and be widely used in concrete beam and board,
In the reparation of the engineering structures such as column, bridge pier, it may be said that carbon fiber recovery technique and condition applied to boat structure are very
This technology is applied to the reparation of underwater steel construction, will there is very big research application space by maturation.
Summary of the invention
Traditional underwater recovery technique there are aiming at the problem that, the present invention provide a kind of underwater steel component carbon fiber maintenance plus
Solid method.
The underwater steel member of carbon fiber maintenance and reinforcement is to be transmitted using a kind of special underwater epoxy adhesive as load
Bridge is bonded together damaged member and carbon fiber to form composite component, when composite component is by external force, steel member,
The system shared load of adhesive, carbon fiber composition, generates Relative sliding between steel member and carbon fiber, internal system will
There is shear stress, and be stress maximum value at adhesive surface both ends, gradually successively decreases along Impact direction to centre.In the process
With the transmitting puted forth effort, the load that steel plate undertakes constantly reduces, and the total bearing capacity of composite component is constant, so carbon fiber is held
The power of load just constantly increases, so that carbon fiber has shared the fractional load of damaged member, reduces the load that damaged member undertakes,
To achieve the purpose that maintenance and reinforcement.
To achieve the goals above, the technical solution of the present invention is as follows:
A kind of method of underwater steel component carbon fiber maintenance and reinforcement, main includes that the impaired steel plate of simulation and carbon cloth are clear
Clean drying, roughening treatment, underwater epoxy adhesive preparation, the smearing of adhesive, underwater curing and etc..Specific step is as follows:
Step 1: repeatedly wiping steel plate original surface 1 using organic solvent, removes surface and oil contaminant, damages on steel plate original surface 1
Hurt notch, damage indentation, there is to damage section 6.
Step 2: by step 1, treated that steel plate is put into carries out deep layer in the supersonic wave cleaning machine equipped with solvent and deoil
It is dirty.It is not further added by the fat content in organic solvent, steel plate is taken out, using distilled water or inorganic salts warm water washing steel plate table
Face is then dried steel plate.
Step 3: roughening treatment is carried out to steel plate original surface 1 and fiber cloth surface
After degreasing, using the reparation section 7 of angle grinder polishing steel plate original surface 1, wherein repairing in section 7 comprising damage section 6；
