Description
Technical field
It is more particularly to a kind of to utilize pre-stress FRP cloth the invention belongs to the structural strengthening such as science of bridge building, architectural engineering field
The method of reinforced steel concrete pier stud.
Background technology
Fibre reinforced composites FRP(Fiber Reinforced Plastic)Good mechanical performance, chemical property is steady
It is fixed, with high-strength, lightweight, it is corrosion-resistant, play the characteristics such as mould is high, proportion is small, its thermal coefficient of expansion is close with concrete, is answered extensively
Reinforcing for concrete structure.Common constraint of the FRP material to concrete component belongs to " passive bound ", only in concrete
Fully under expansion, FRP material just starts to play effect of contraction, there is a certain degree of Stress resort, the high-strength performance of FRP material
It is not in full use.Pre-stress FRP cloth reinforcement technique is a kind of active reinforcement means, utilizes FRP high-strength characteristic so that
The concrete column of hoop constraint has the initiative three dimension stress state, improves the bearing capacity, shock resistance, consumption of performance of concrete column confined
Can ability, ductile performance.
At present, the stretching and anchoring device in pre-stress FRP cloth reinforced concrete pier stud construction method is mostly permanent, anchor
Tool is not reproducible to be utilized, and cost is higher.And anchorage is exposed at pier stud surface, architectural appearance is not only influenceed, and easily cause people to note
Anticipate the structural strengthening, so that psychologically the safety to structure throws doubt upon.In addition, FRP cloth is twined in conventional tension ground tackle
It is wound on intermediate plate or roller bearing, prestressing force is applied by the tensioning screw rod for tightening two ends, when FRP cloth is wider or prestressing force is larger
When, intermediate plate or roller bearing flexural deformation are larger so that FRP cloth discontinuity and prestress application are not enough.

On plate.After after colloid solidification, FRP cloth was around one week at Reinforced Concrete Pier Column Reinforcing position.The tensioning anchor at tension ground tackle two ends
Have the installation anchor hole at anchor hole alignment bottom plate two ends, crab-bolt is through tension ground tackle anchor hole and installs anchor hole, make bottom plate and
Tension ground tackle is fixedly connected.Tensioning screw rod is arranged in the screw of tension ground tackle respectively.
(2) the reinforcing position being reinforced on Reinforced Concrete Pier Column is determined;It need to carry out in advance should in the ejection of its surface with the line of ink marker
Power FRP cloth parcel position range, to reinforce surface of position polished, filling-up hole, finally to being reinforced Reinforced Concrete Pier Column
The FRP cloth parcel scope on surface uniformly brushes one layer of epoxy adhesive layer.
(3) cutting length and the cutting of FRP cloth are determined;Reinforced Concrete Pier Column at cutting length=parcel location of FRP cloth
Girth add 1 ~ 2 times of girth of bottom plate.
(4) backplate surface is uniformly applied winds circle on bottom plate after glue, FRP cloth two ends gluing.Fix FRP cloth two ends
It is pasted onto on bottom plate.After colloid solidification, the installation anchor hole at the tension ground tackle anchor hole alignment bottom plate two ends at tension ground tackle two ends,
Crab-bolt is through tension ground tackle anchor hole and installs anchor hole, bottom plate is fixedly connected with tension ground tackle.
(5) FRP cloth for connecting bottom plate and tension ground tackle that step (4) is obtained is looped around adding for Reinforced Concrete Pier Column
Maintenance puts place one week, synchronously tightens tensioning screw rod, and prestressing force is applied to FRP cloth.
(6) after the prestressing force for putting on FRP cloth reaches predeterminated level.Glue is filled into FRP cloth surface, and fills it
Sub-dip is moistened, and is waited and is pasted adhesive curing.
(7) drilled at the bottom plate anchor hole at bottom plate two ends to Reinforced Concrete Pier Column, thereafter by plastic expansion plug glue
Hammer is knocked in hole.Insert setscrew and be screwed into Reinforced Concrete Pier Column.Bottom plate is fixed on institute's reinforced steel concrete pier
On post.
(8) after the stickup adhesive curing applied in FRP cloth, unscrew the crab-bolt between tension ground tackle and bottom plate, unload tensioning
Anchorage and tensioning screw rod.Drill, thereafter knock in plastic expansion plug glue hammer to Reinforced Concrete Pier Column at anchor hole installing
In hole, insert setscrew and be screwed into Reinforced Concrete Pier Column.
(9) the bond-anchorage FRP cloth on two bottom plates, it is ensured that apply the bond-anchorage length of prestressed FRP cloth, i.e.,
Realize and utilize pre-stress FRP cloth reinforced steel concrete pier stud.
The bottom plate is chosen be close to square column surface respectively according to Reinforced Concrete Pier Column is reinforced for square column or cylinder
Flat board or the arc plate be close to periphery;When being reinforced Reinforced Concrete Pier Column for square column, except right in step (2)
Reinforce surface of position to be polished, beyond filling-up hole, four corners polishing chamfering to square column is also needed, finally again to being reinforced reinforcing bar
The FRP cloth parcel scope on performance of concrete column confined surface uniformly brushes one layer of epoxy adhesive layer.
The inventive method is contrasted with prior art, and advantage is:(1)The pre-stress FRP cloth used in the inventive method
The tension ground tackle of bracing means can be removed conveniently, be reused, and save material, cost-effective, environmental protection and energy saving.(2)Present invention side
Method reinforce after pier stud cosmetic variation less, do not influence after reinforcing the sight built and use function.(3)The inventive method is operated
Simply, the efficiency for implementing the novel reinforced device can be effectively improved, it is easy to utilize.
