Abstract
The utility model provides a kind of air bag of the affixing carbon fabric on concrete structure, is spill after the airbag aeration, includes bottom wall for installing carbon cloth and two side connect with the bottom wall, the side wall is positioned in the bottom wall both sides.The air bag of the affixing carbon fabric provided by the invention on concrete structure, can reinforce the bond effect of carbon cloth, improve the bearing capacity and durability of structure.
Description
Technical field
The air bag of the present invention relates to a kind of on concrete structure affixing carbon fabric.
Background technology
China has created the structures such as large quantities of bridges, harbour, house in the 80s and 90s in last century, and by now, this batch is built
It builds and has been subjected to serious corrosion failure, there is an urgent need for repairing and reinforcings, especially dock structure, and corrosive environment is especially severe, design the longevity
Life is also shorter, and in order to improve the bearing capacity and durability of structure, sticking carbon fiber, which is reinforced, is undoubtedly most effective reinforcing means
One of.Carbon fiber is that high-strength, corrosion-resistant, the heat safe light composite material of one kind is played as long as during structural strengthening
The advantage of carbon fiber can greatly improve the bearing capacity and durability of structure.
Experimental study and engineering practice both domestic and external show main with the success or not of carbon cloth reinforced concrete structure
Quality depending on adhesive property between carbon cloth and concrete structure.Guaranteed, the carbon fiber in bond quality
The good physical of cloth can give full play to, and the reliability of reinforcing is high；Conversely, may result in carbon fiber when adhesive property difference
Cloth performance just occurs to bond stripping damage before giving full play to, and not only causes waste of material, but also reduce the reliability of reinforcing.Change at present
The bond effect of kind carbon fiber, generally sets about in terms of material, such as improves the adhesion strength of adhesive glue, shortens the solidification of adhesive glue
Time etc., but construction site situation is complicated, and temperature, humidity, dexterity of operation etc. may all enable bonding for adhesive imitate
Fruit is not in full use, and the improvement of material property can not be completely counterbalanced by carbon fiber and adhesive glue under Gravitative Loads with coagulation
The trend that soil structure is detached from.
When reinforcing concrete in water level change region structure, due to forming a large amount of water vapor hole under hydraulic pressure, carbon fiber pastes effect
Fruit can significantly reduce.Current technology means tend not to solve the problems, such as this well.
Invention content
Based on the above deficiency, the technical problem to be solved in the present invention is to provide one kind on concrete structure sticking carbon fiber
The air bag of cloth can reinforce the bond effect of carbon cloth, improve the bearing capacity and durability of structure.
In order to solve the above technical problems, present invention employs following technical schemes：
A kind of air bag of the affixing carbon fabric on concrete structure is spill after the airbag aeration, including is used to pacify
The two side for filling the bottom wall of carbon cloth and being connect with the bottom wall, the side wall are located in the bottom wall both sides.
The bottom wall width is less than the width of concrete structure.
The bottom thickness of the air bag is 15-25cm.
The bottom wall of the air bag to the ratio of the distance on side wall top and the bottom thickness of air bag be 0.8~1.2.
The air bag outer wrapping Anti-adhering plastic film.
It protrudes outward to form protruding portion after the side wall inflation of the air bag.
Using above technical scheme, the present invention achieves following technique effect：
The air bag of the affixing carbon fabric provided by the invention on concrete structure by carbon cloth and can mix after inflation
Xtah Crude Clay structure bonds, and can provide carbon cloth the pressure on top surface towards concrete structure, ensures all carbon cloths and mixes
Xtah Crude Clay structure comes into full contact with so that adhesive glue solidifies under the pressure effect of consistent, improves bond effect, improves structure
Bearing capacity and durability.

Fig. 2 is the structure chart of concrete structure；
Fig. 3 is the schematic diagram for the lower section that the air bag with carbon cloth of unaerated is placed in concrete structure；
Fig. 4 is to making carbon cloth fit closely the schematic diagram of concrete structure after airbag aeration.
Specific implementation mode
As shown in Figure 1 and Figure 4, the air bag 1 of the present invention provides a kind of on concrete structure affixing carbon fabric, air bag
It is spill after 1 inflation, includes bottom wall 11 for installing carbon cloth 3 and the two side 12 being connect with bottom wall 11, side wall 12
In the both sides of bottom wall 11.
Air bag 1 is made of latex material, is concave after inflation, outer wall thickness in 3mm hereinafter, inner wall thickness is 5mm or so,
The width of bottom wall 11 is less than the width of concrete structure 2.The length of bottom wall 11 is more than carbon fiber and pastes length, the bottom of air bag 1
13 thickness is 15cm-25cm.Ratio of the bottom wall 11 of air bag 1 to the distance on 12 top of side wall and the thickness of the bottom 13 of air bag 1
Value is 0.8~1.2.The side wall 12 of air bag 1 protrudes outward to form protruding portion after inflating, for clamping concrete structure 2.Air bag 1
Outer wrapping Anti-adhering plastic film.Air inflation nozzle 14 is additionally provided on air bag.
The present invention also provides a kind of methods based on air bag affixing carbon fabric on concrete structure, including
Following steps：
(1) carbon cloth 3 is installed on the bottom wall 11 of air bag 1；
(2) it is positioned in the pre- sticky cloth position unwrapping wire of concrete structure according to arrangement and method for construction；
(3) the pre- sticky cloth position of concrete structure 2 is surface-treated, including：
(31) beam body at the pre- sticky cloth position of polishing, removes the concrete structure of deterioration；
(32) seam protrusion part at beam body faulting of slab ends is cut, so that the faulting of slab ends part gradient is reduced, smooth-going；
(33) polishing concrete structural surface is to exposing fresh layer；
(34) chamfered is carried out to concrete structure corner location for paste, and is polished into arc-shaped；
(35) there is the large area larger position that is recessed to concrete structure after polishing and carry out equating with epoxy-like materials.
(4) prepare and in the pre- sticky cloth position brushing primer of concrete structure, including：
(41) the pre- sticky cloth position that concrete structure is cleared up with alcohol, makes it keep drying；
(42) primer is prepared, the amount prepared every time is subject to a piece of beam dosage；
(43) the brushing primer on pre- sticky cloth position, when brushing, should make every effort to uniform and thin, reinforcing bar and uneven etc. be difficult to
Brushing position must brush repeatedly, and brushing thickness is within 1mm.
(5) after brushing primer in half an hour, the air bag 1 of unaerated is positioned over side under concrete structure, adjusts gas
1 position of capsule ensures that concrete structure can be clamped by inflating rear gasbag 1, and compresses carbon cloth 3 completely.
(6) it uses air compressor machine to inflate air bag 1, air bag 1 is made mutually to be close to and come into full contact with concrete structure 2；Wait for carbon
After fiber cloth 3 comes into full contact with 2 concrete structure of concrete structure, air pressure is maintained at 0.3MPa or more, continues more than half an hour
The step of.
(7) connection for releasing air bag 1 and carbon cloth 3, deflates to air bag 1, removes air bag 1.
Finally it should be noted that：It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, although
With reference to embodiment, invention is explained in detail, for those skilled in the art, still can be to aforementioned
Technical solution recorded in each embodiment is modified or equivalent replacement of some of the technical features, but it is all
