Abstract
The utility model relates to a built-in anti-corrosion structure for a pre-stress hollow square pile. The built-in anti-corrosion structure for the pre-stress hollow square pile mainly comprises the pre-stress hollow square pile, wherein a central through hole penetrating the whole pre-stress hollow square pile is formed in the center of the pre-stress hollow square pile in the length direction of the pre-stress hollow square pile, the cross section of the periphery of the pre-stress hollow square pile is square, and the pre-stress hollow square pile mainly comprises a steel reinforcement cage, a concrete layer and end plates, the steel reinforcement cage is composed of main bars and hooping bars, the concrete layer wraps the steel reinforcement cage, the section of the whole concrete layer is square, the end plates are respectively arranged at the two ends of the concrete layer, and the anti-corrosion structure is arranged on the outer surface of the steel reinforcement cage. The built-in anti-corrosion structure for the pre-stress hollow square pile has the advantages that anti-corrosion structures are arranged on the outer surface of the steel reinforcement cage and the outer surfaces of the end plates, can effectively relieve the corrosion to the steel reinforcement cage and the end plates when the ground layer corrodes the hollow square pile, and prolong the service life of the steel reinforcement cage and the end plates.
Description
Technical field
The utility model relates to a kind of built-in pre-stress hollow square pile anticorrosion structure, a kind of pre-stress hollow square pile that can improve the antiseptic property of hollow square pile specifically.
Background technology
The pre-stressed concrete hollow square stake is a kind of elongated square-outside and round-inside uniform section precast unit that professional factory adopts the techniques such as pretensioned prestressing, centrifugal forming and stream curing to make, and is transported to the soil spreading and sinks to the underground basis that becomes building.Its applicable stratum is that stream is moulded, the soft foundation of soft-plastic state, and bearing stratum is preferably argillic horizon, layer of sand, buried basement rock, and the stratum of severely-weathered rock stratum or Weathering-residual thicker soil, is particularly useful for the ground that soft layer is thicker.
At present, and at present, pre-stress hollow square pile in using on existing market, its after implanting stratum, after after a while, the whole hollow square pile of corrosion from outside to inside that stratum can be gradually, finally can corrode the reinforcing cage in hollow square pile, and make the reinforcing cage damage, and reduce its application life, finally cause reduced the application life of whole hollow square pile.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of pre-stress hollow square pile that can improve the antiseptic property of hollow square pile.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of built-in pre-stress hollow square pile anticorrosion structure, and its innovative point is: mainly comprise a pre-stress hollow square pile;
At the pre-stress hollow square pile center, have a central through hole that runs through whole pre-stress hollow square pile along described pre-stress hollow square pile length direction, the periphery cross section of described pre-stress hollow square pile is square;
Described pre-stress hollow square pile mainly comprises reinforcing cage, layer of concrete and end plate, reinforcing cage is comprised of some main muscle that extend along the hollow square pile length direction and spiral stirrup two parts around described main muscle, in described layer of concrete is wrapped in reinforcing cage, and the cross section of monolithic concrete layer is square-shaped, described end plate is separately positioned on the two ends of layer of concrete;
On the external surface of described reinforcing cage and end plate, be provided with anticorrosion structure.
Further, described anticorrosion structure is specially: on the external surface of the main muscle of reinforcing cage and stirrup, be provided with one deck corrosion resistant coating, and also be provided with one deck corrosion resistant coating on the external surface of end plate.
The utility model has the advantage of: will on main muscle, stirrup and the end plate of reinforcing cage, smear one deck corrosion resistant coating; when stratum will the corrosion reinforcing bar cage; corrosion resistant coating can fine protection reinforcing cage; slow down the corrosion of stratum to it, increase the application life that finally makes whole hollow square pile application life that has increased reinforcing cage.
The accompanying drawing explanation
Fig. 1 is the elevation of built-in pre-stress hollow square pile anticorrosion structure of the present utility model.
Fig. 2 is the lateral view of built-in pre-stress hollow square pile anticorrosion structure of the present utility model.
The specific embodiment
As can be known by schematic diagram shown in Figure 1, pre-stress hollow square pile anticorrosion structure of the present utility model is mainly a pre-stress hollow square pile, and pre-stress hollow square pile mainly is comprised of reinforcing cage, layer of concrete 4 and end plate 3 these three parts.
Reinforcing cage mainly is comprised of main muscle 1 and stirrup 2 these two parts, main muscle 1 has some, length direction along pre-stress hollow square pile extends, all main muscle 1 are uniformly distributed round the circumferencial direction of pre-stress hollow square pile, and the rounded shape of all main muscle 1 distributes, stirrup 2 integral body in the shape of a spiral, and be rotated winding round all main muscle 1, in layer of concrete 4 is wrapped in whole reinforcing cage, and whole layer of concrete 4 is rectangular structure, the cross section of layer of concrete 4 is square-shaped, end plate 3 is separately positioned on the two ends of layer of concrete 4, on the external surface of reinforcing cage and end plate, be provided with anticorrosion structure.
Anticorrosion structure is specially: at the main muscle 1 of reinforcing cage and the external surface of stirrup 2, be coated with uniformly one deck corrosion resistant coating 8, on the external surface of end plate 3, also be coated with uniformly one deck corrosion resistant coating 8 simultaneously.
As can be known by schematic diagram shown in Figure 2, in the center of pre-stress hollow square pile, be provided with a central through hole 5, central through hole 5 runs through whole pre-stress hollow square pile along the pre-stress hollow square pile length direction, the periphery cross section of pre-stress hollow square pile is square, the cross section of central through hole 5 also is square, and the distance between each seamed edge 6 of the cross section of square central through hole 5 and the seamed edge of end plate 3 equates, the angle between every adjacent two seamed edges 6 is arc chord angle 7.
The cross section of the central through hole 5 in the present embodiment also can rounded shape, and the center of the cross section of the center of circle of the cross section of central through hole 5 and end plate 3 is same point.
