Abstract
A kind of reinforced column class strengthening member processing step based on vacuum suction method is that fluid sealant is coated above and below reinforced column to be reinforced, and carbon cloth, terylene release cloth and water conservancy diversion ethene screen cloth are spread successively；Vacuum bag is then covered with, resin inlet and bleeding point are set, vavuum pump is opened and vacuumizes, when the full vacuum bag of the vinylite stream in plastic holding device, allows internal resin wetting fibre, after vinylite fully solidifies, to tear off complete after terylene release cloth and reinforce.The present invention is realized by the flowing and infiltration of vinylite utilizes fibre reinforced composites cloth reinforced steel concrete post, the fibre reinforced composites cloth of this method reinforced steel concrete post can carry out fibrous layer numerical control system as needed, and the reinforcing face that can preferably fit, suitable for different curvature curved surface reinforcement of concrete post, can be with global formation and without glue water clock, simply, easily operation, non-environmental-pollution, cost are relatively low for its technique, and the interface mechanical characteristic after reinforcing is excellent.
Description
Technical field
The present invention relates to reinforced concrete structure reinforcement process, especially a kind of armored concrete based on vacuum suction method
Post class strengthening member technique.
Background technology
Reinforced concrete structure due to its materials easily, fire resisting, durable, good integrity and the low advantage of price, by
It is largely used to the fields such as residential housing, bridge and road.But concrete is easy to crack and reinforcement corrosion etc. causes its performance
Decline, reinforced concrete structure can not carry out welding procedure reinforcing as steel construction, it is also difficult to change.
Fibre reinforced composites (Fiber Reinforced Polymer, abbreviation FRP) are by fibrous material and matrix
Material is mixed and by the high-performance novel structural material of certain process combining formation, with high-strength light, resisted by a certain percentage
The remarkable advantages such as tired, corrosion-resistant and construction molding convenience, are used for military project and aerospace field earliest.By the technical staff
Skill, which is applied, to be used in civil engineering, and existing process is that post class component surface will be affixed on outside FRP cloth, in construction by fiber cloth
Make cloth and component formation reinforced surface after being rolled after outer patch with roller, the shortcoming of this technique is that redundant structure glue water clock can be made to exist
Stabilization zone or other workspaces, it is difficult that arrival is actually needed with FRP interfaces to roll the structure formed, and the structural plane formed is uneven
It is whole.
The content of the invention
It is an object of the invention to provide a kind of simple to operate, low cost, non-environmental-pollution, interface mechanical characteristic after reinforcing
The excellent reinforced column class strengthening member technique based on vacuum suction method.
The reinforced column class strengthening member technique based on vacuum suction method of the present invention, comprises the following steps：
1st, concrete is exposed into the removing of plastering on reinforced column surface to be reinforced, following peripheral on region is coated needing reinforcement
Fluid sealant；
2nd, according to reinforcing, central area is thick, the thin principle paving carbon cloth in side, and spreads terylene release cloth and water conservancy diversion second successively
Alkene screen cloth；
3rd, vacuum bag is then covered with, vacuum bag is connected with the fluid sealant of following peripheral on the region that needs reinforcement, and sets resin inlet
And bleeding point, check the air-tightness of vacuum bag, it is ensured that vacuum bag spaced apart regions air-tightness is good；
4th, add the curing agent of 1-3% ratios to vinylite and stir, pacify between resin inlet and plastic holding device
Fill PE pipes, set on PE pipes resin to inject valve, bleeding point is connected by PE pipes with resin trap, resin trap and meanwhile with
Vavuum pump is connected；
5th, resin injection valve is closed, after opening vavuum pump is vacuumized, then resin injection valve is opened, when the second in plastic holding device
During the full vacuum bag of ene based resins stream, vavuum pump is closed, the abundant wetting fibre of internal resin is allowed；
6th, after vinylite fully solidifies, the reinforcing that reinforced column class is completed after terylene release cloth is torn off.
The reinforced column class strengthening member technique based on vacuum suction method of the present invention, passes through the stream of vinylite
Dynamic and infiltration is realized adds reinforced column class component, this method reinforced steel concrete post using fibre reinforced composites cloth
The fiber number of plies of fibre reinforced composites can be designed and laid as needed, and preferably be fitted with reinforcing face, it is adaptable to different
Curvature surface reinforcement of concrete post, can be with global formation and without glue water clock, and its technique is simple, easily operate, without environment dirt
Dye, cost are relatively low, and the interface mechanical characteristic after reinforcing is excellent.

Embodiment
A kind of reinforced column class strengthening member technique based on vacuum suction method, comprises the following steps：
1st, concrete is exposed into the removing of plastering on the surface of reinforced column 10 to be reinforced, following peripheral on region is applied needing reinforcement
Good fluid sealant 11；
2nd, according to reinforcing, central area is thick, the thin principle paving carbon cloth 12 in side, and spreads terylene release cloth 13 successively and lead
Flow ethene screen cloth 14；
3rd, vacuum bag 15 is then covered with, vacuum bag 15 is connected with the fluid sealant 11 of following peripheral on the region that needs reinforcement, and sets resin
Inlet 5 and bleeding point 6, check the air-tightness of vacuum bag, it is ensured that vacuum bag spaced apart regions air-tightness is good；
4th, add the curing agent of 1-3% ratios to vinylite 1 and stir, resin inlet 5 and plastic holding device 1 it
Between install and set on PE pipes 4, PE pipes 4 resin and inject valve 3, bleeding point 6 is connected by PE pipes 4 with resin trap 7, resin receipts
Storage 7 is connected with vavuum pump 9 simultaneously；
5th, resin injection valve 3 is closed, after opening vavuum pump 9 is vacuumized, then resin injection valve 3 is opened, when in plastic holding device 1
