The specific embodiment
Below in conjunction with Figure of description the present invention is further specified:
The FRP fibre cloth winding is around stake; Cooperate by some longitudinal reinforcement 3, some reinforcing cage stirrups 1 and FRP cloth 4 and to form; Reinforcing cage stirrup 1 is the circular configuration that has some ringlets 2 that a reinforcing bar is processed; Longitudinal reinforcement 3 is provided with the ringlet 2 grafting close-fittings of reinforcing cage stirrup, and the longitudinal reinforcement 3 that cooperates of pegging graft constitutes reinforcing cage, all bonding FRP cloth 4 that is provided with in both sides inside and outside reinforcing cage with reinforcing cage stirrup 1; Constitute the FRP fibre cloth winding around the stake skeleton, constitute the FRP fibre cloth winding around stake at FRP fibre cloth winding equal concreting inside and outside the stake skeleton.
Above-mentioned FRP fibre cloth winding comprises following processing step around the preparation method of stake:
1) preliminary treatment: rust cleaning removes the spot processing to reinforcing bar;
2) make the reinforcing cage stirrup: the reinforcing cage stirrup is a circular configuration that is become by reinforcement fabrication; Connect the longitudinal reinforcement place at needs and reverse ringlet of 180 ° of coileds; The quantity of ringlet is identical with the longitudinal reinforcement number that needs to peg graft on the reinforcing cage stirrup, and when the reinforcing cage stirrup was connected with longitudinal reinforcement, longitudinal reinforcement directly inserted in the circle; More be of value to its performance three dimension stress state when having guaranteed the fastening of connection and stake pressurized, improve bearing capacity;
3) several transverse reinforcement cage stirrups of reinforcing cage making: with step 2) processing are connected with longitudinal reinforcement, are about to longitudinal reinforcement and are plugged in the ringlet on the reinforcing cage stirrup, and several reinforcing cage stirrups evenly are set on longitudinal reinforcement as required;
4) the FRP fibre cloth winding is around the stake carcassing: the FRP cloth is parallel to longitudinal reinforcement with resin and is bonded in both sides inside and outside the reinforcing cage that step 3) makes, the lap length of FRP cloth is 14-16 centimetre, is generally about 15 centimetres; After all vertical bonding one deck FRP cloth in both sides inside and outside the reinforcing cage; Bonding second layer FRP cloth is distinguished in both sides inside and outside reinforcing cage again; This second layer FRP cloth is with respect to being vertical or skewed setting with first floor FRP cloth; The lap length of second layer FRP cloth is 14-16 centimetre, is generally about 15 centimetres; The lap-joint of second layer FRP cloth and first floor FRP cloth need interlock bonding;
5) the FRP fibre cloth winding is made around stake: the FRP fibre cloth winding that step 4) is made gets in the hole of having accomplished fluently around the lifting of stake skeleton; Concreting is built inside and outside the stake skeleton the FRP fibre cloth winding when building simultaneously, and the concrete discrepancy in elevation of control FRP fibre cloth winding inside and outside the stake skeleton is not more than 20 centimetres; The one-time-concreting height is not more than 2 meters; And in time vibrate, build and finish, promptly the FRP fibre cloth winding is made around stake and is finished.
The FRP cloth comprises CFRP cloth (carbon fiber), GFRP cloth (glass fiber), BFRP cloth (basalt fibre) and AFRP cloth (aramid fiber) among the present invention.
Reinforcing cage stirrup of the present invention also can be set to square or other structures as required.
The structure of reinforcing cage stirrup of the present invention is very unique; Can closely cooperate with reinforcing bar; Play effect good and that reinforcing bar interfixes; The number that the reinforcing cage stirrup is set on longitudinal reinforcement can be set fully as required, and the quantity of ringlet is also set according to the thickness of stake on the reinforcing cage stirrup, guarantees the reliability that connects.Inside and outside reinforcing cage, all paste the FRP cloth, and bonding two-layer, be crisscross arranged between two-layer, guarantee its bearing capacity and firmness; Because cloth has the tensile strength height, anti-fatigue performance is good, and resistance to corrosion is strong, the advantage of low price etc., and especially the adhesion with resin is strong, when being connected with reinforcing bar, has the close and firm excellent characteristic.After FRP cloth and reinforcing cage winding stickup, its formation has the structure of similar properties of steel pipes.After concreting is accomplished, by the lock ring effect of contraction of this structure, make core concrete be in triaxial stress state to core concrete, improved the bearing capacity and the non-deformability of single pile greatly, compare tool with castinplace pile and have great advantage.Owing to reduce the use of steel, reduced cost, and, had the incomparable advantage of steel pipe pile because the corrosion resistance of FRP cloth need not carried out preservative treatment again.
