A part for described cuff cladding pile body；Described end plate is fixing with cuff to be connected.The concrete strength of described concrete pile body
For C60～C80.The inner side of described end plate is fixedly connected with anchor rib, and described non-prestressing tendon is fixing with anchor rib to be connected.
It is circumferentially provided with indenture along described cuff.The wall thickness of described concrete pile body is 80～130 millimeters.
Beneficial effect: the prestressed high-strength concrete pile of this utility model lattice form of reinforcement uses the tubular steel that butt welding is formed
Muscle net welds formation framework of steel reinforcement as stirrup with deformed bar, uses high-strength concrete to pour, and the pile tube formed exists
When bearing horizontal loading, the framework of steel reinforcement that can be formed by grid arrangement of reinforcement, for pile tube provide higher anti-side rigidity and
Suppression diagonal crack produces and the ability of development.
Grid form of reinforcement prestressed concrete pipe pile simple structure of the present utility model: general pile tube manufacturer all may be used
Batch machining produces；Drawing materials conveniently: the steel wide material sources that this utility model uses, complete in specifications, it is convenient to buy, for
The basis having specified level bearing capacity to need selects to provide a kind of new pile-type.

Detailed description of the invention
Preferred implementation of the present utility model is described in detail below in conjunction with accompanying drawing, but, on this utility model is not limited to
State the detail in embodiment, in technology concept of the present utility model, can be to technology of the present utility model
Scheme carries out multiple equivalents, and these equivalents belong to protection domain of the present utility model.
As shown in Figure 1 to Figure 3, this embodiment is partially prestressed concrete barrette, and it mainly includes the second prestressing force
Reinforcing bar 201, the second pile concrete 202, the second bar-mat reinforcement 203, the second non-prestressing tendon 204, the second steel hoop 205,
Second end plate 206 and the second steel hoop indenture 207.
Wherein, pile concrete selects C60～C80.Pile concrete, by the consumption requirement of every centrifugal pile tube, uses cloth
Fresh concrete is uniformly filled up female die by truck along mould, at stretch-draw one end some concrete of the most cloth.Pile body mixes
Solidifying soil wall thickness takes 80～130mm.Grid in bar-mat reinforcement is rhombus.Bar-mat reinforcement is increasing in interval, three times of stake footpaths of stake end
Big mesh-density, to reach cipher round results.The steel grid of bar-mat reinforcement is according to the difference of required bending resistance shear-carrying capacity, steel
Reinforced net angulation is the most different, in the range from 30 °～150 °.The network length of side span of bar-mat reinforcement exists
50mm～400mm.The reinforced steel bar strength used of bar-mat reinforcement, according to the difference of required bending resistance shear-carrying capacity, can be selected for hot calendering
Round reinforcing bar or employing first class cold-drawn low-carbon wire.Bar diameter used by described bar-mat reinforcement is according to selected bar types not
With otherwise varied, the round bar diameter of hot calendering between choose 6～10mm, and first class cold-drawn low-carbon wire diameter exists
4～8mm.Nonprestressed reinforcement is different from ductility according to required bending strength, arranges one between every deformed bar
Root non-prestressing tendon, it is possible to often arrange a nonprestressed reinforcement between several deformed bars.The steel of nonprestressed reinforcement
Rigidity of soft tissues degree is according to the difference of required bending strength, and its reinforcing bar can be HPB300, HRB335, HRB400 and HRB500.
The diameter of nonprestressed reinforcement is unsuitable with deformed bar different diameters excessive.It is limit that square pile tube two ends are equipped with steel hoop
The long thin-walled square steel tube equal with the square pile tube length of side, end plate is the square hollow steel plate identical with square pile tube cross section, end
Plate is welded on steel hoop one rear flank and is arranged on an end.It is welded with inside end plate and non-prestressing tendon same specification, the anchor of equivalent amount
Gu muscle, welding distributed points is basically identical with pile body non-prestressing tendon position.Use between non-prestressing tendon and anchor bar and tie up
The mode pricking overlap joint connects, and anchor rib uses the mode of weld all around or stopple weldering to be connected with end plate.Steel hoop is provided with two on surface
Bar indenture.Indenture is arranged at steel hoop, along the lateral arrangement two of steel hoop.
In this embodiment, longitudinal prestressing reinforcing bar and the non-pre-of the prestressed concrete quadrate shape pile tube of grid form of reinforcement should
Power muscle is wrapped up by steel grid, and overall steel reinforced net is increasing mesh-density layout in interval, three times of stake footpaths of stake end, and root
Network angle and the length of side is suitably adjusted according to being actually needed.The prestressed concrete quadrate shape pile tube two ends of grid form of reinforcement
Being equipped with the thin-walled rectangular steel tube cuff that the length of side is equal with the pile tube length of side, end plate is and grid form of reinforcement prestressed concrete
The square hollow steel plate that square pile tube cross section is identical, end plate is welded on steel hoop one rear flank and is arranged on an end, adds inside end plate
Weldering and non-prestressing tendon same specification, the anchor rib of equivalent amount, welding distributed points and pile body non-prestressing tendon position basic
Cause.The mode using colligation overlap joint between non-prestressing tendon with anchor bar is connected, and anchor rib uses weld all around or hole with end plate
The mode of plug welding connects.
This embodiment is to rely only on, for existing square pile tube, the framework of steel reinforcement that tie hoop and presstressed reinforcing steel formed to bear
The horizontal loading of pile tube, the prestressed concrete quadrate shape pile tube of grid form of reinforcement uses the bar-mat reinforcement of butt welding formation as hoop
Muscle, welds formation framework of steel reinforcement with deformed bar, nonprestressed reinforcement, uses high-strength concrete to pour, is formed
