Description

A kind of method of utilization pre-stress FRP cloth reinforced steel concrete pier stud
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.
The content of the invention
It is an object of the invention to provide a kind of method of utilization pre-stress FRP cloth reinforced steel concrete pier stud.The party Method uses a kind of novel pre-stressed FRP cloth bracing means of Reinforced Concrete Pier Column, using the device to FRP cloth stretch-draw anchor Afterwards, tension ground tackle conveniently can be removed and reused, cost-effective;And pier stud does not have exposed anchorage after reinforcing, and does not influence It is reinforced the outward appearance of pier stud.It is applicable to that FRP cloth is wider and the larger reinforcing operating mode of prestressing force.
Concretely comprise the following steps:
(1) a kind of device of utilization pre-stress FRP cloth reinforced steel concrete pier stud is set, and the device includes two bottom plates, two Individual tension ground tackle, tensioning screw rod and FRP cloth;Bottom plate wraps up direction two ends inverted arc angle along FRP cloth, in case it scratches FRP cloth;Bottom plate Bottom plate anchor hole is opened up respectively perpendicular to FRP cloth parcel direction two ends and anchor hole is installed;Tension ground tackle upper and lower ends perpendicular to FRP cloth direction respectively opens up two tension ground tackle anchor holes;Tension ground tackle opens up two spiral shells respectively along parallel to FRP cloth parcel direction Hole;Winding 2 ~ 3 is enclosed on bottom plate after backplate surface uniform gluing, FRP cloth two ends gluing, is fixed FRP cloth two ends and is pasted onto bottom 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.
