Steel reinforcement cage in soil pile body, described steel reinforcement cage includes presstressed reinforcing steel and fixes the tubular reinforcing bar being connected with described presstressed reinforcing steel
Net.
In a further embodiment, described tubular bar-mat reinforcement is formed, in bar-mat reinforcement by the some groups of reinforcement welding interlocked
Grid is rhombus；The side size range of network is 50～400 millimeters.Net near the bar-mat reinforcement of concrete pile body end plate
Lattice density is more than the mesh-density of the bar-mat reinforcement in the middle part of concrete pile body.In described bar-mat reinforcement, the angle of grid is 30 °
～150 °.The end of described concrete pile body is provided with end plate and cuff, described cuff cladding concrete pile body, described end
Plate and the fixing connection of cuff.The intensity of described concrete pile body is C60～C80.It is circumferentially provided with indenture along described cuff.
Beneficial effect: the prestressed concrete quadrate shape pile tube of this utility model grid form of reinforcement uses the reinforcing bar that butt welding is formed
Net, as stirrup, welds formation framework of steel reinforcement with deformed bar, nonprestressed reinforcement, uses high-strength concrete to pour,
The square pile tube formed is when bearing horizontal loading, and the framework of steel reinforcement that can be formed by grid arrangement of reinforcement, for square pile tube
Higher anti-side rigidity and suppression diagonal crack is provided to produce and the ability of development.
Grid form of reinforcement prestressed concrete quadrate shape pile tube simple structure of the present utility model: general pile tube factory
Family all can batch machining produce；Draw materials conveniently: the steel wide material sources that this utility model uses, complete in specifications, buy just
Profit, the basis for there being specified level bearing capacity to need selects to provide a kind of new pile-type.
Accompanying drawing explanation
Fig. 1 is longitudinal semi-section schematic diagram of the present utility model.
Fig. 2 is cross sectional representation of the present utility model.
Fig. 3 is end view of the present utility model.
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 Figures 1 to 3, this embodiment is prestressed concrete quadrate shape pile tube, and it mainly includes the first deformed bar
101, the first pile concrete 102, the first bar-mat reinforcement 103, the first steel hoop (pile protection hoop, cuff) 104, first
End plate 105 and the first steel hoop indenture 106.
Wherein, pile concrete selects C60～C80, by the consumption requirement of every centrifugal pile tube, uses charge car newly to mix
Concrete uniformly fills up female die along mould, and at stretch-draw one end some concrete of the most cloth, pile concrete wall thickness takes
80～130mm, the grid in bar-mat reinforcement is rhombus, and bar-mat reinforcement is increasing mesh-density in interval, three times of stake footpaths of stake end,
To reach cipher round results, according to the difference of required bending resistance shear-carrying capacity, steel grid angulation is the most different, its
Scope is 30 °～150 °.Network length of side span is at 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 the round reinforcing bar of hot calendering or employing first class cold-drawn low-carbon wire.Steel
Bar diameter used by muscle net is otherwise varied according to selected bar types difference, the round bar diameter of hot calendering between select
Take 6～10mm, and first class cold-drawn low-carbon wire diameter is 4～8mm.It is that the length of side is with square that pile tube two ends are equipped with steel hoop
The thin-walled square steel tube that the pile tube length of side is equal, end plate is the square hollow steel plate identical with square pile tube cross section, and end plate is welded on
Steel hoop one rear flank is arranged on an end.Steel hoop is provided with two indentures on surface.Indenture is arranged at steel hoop, along steel hoop
Lateral arrangement two.
In the present embodiment, the longitudinal prestressing reinforcing bar of the prestressed concrete quadrate shape pile tube of grid form of reinforcement is by bar-mat reinforcement
Lattice wrap up, and overall steel reinforced net is increasing mesh-density layout in interval, three times of stake footpaths of stake end, and fits according to actual needs
When adjusting network angle and the length of side.The prestressed concrete quadrate shape pile tube two ends of grid form of reinforcement be equipped with the length of side with
The thin-walled square bar cuff that the pile tube length of side is equal, end plate is and grid form of reinforcement prestressed concrete quadrate shape pile tube cross section phase
Same square hollow steel plate, end plate is welded on steel hoop one rear flank and is arranged on an end.
This embodiment relies only on the framework of steel reinforcement of tie hoop and presstressed reinforcing steel formation to bear pipe for existing square pile tube
The horizontal loading of stake, 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, uses high-strength concrete to pour, and the square pile tube formed is bearing
During horizontal loading, the framework of steel reinforcement that can be formed by grid arrangement of reinforcement, for square pile tube provide higher anti-side rigidity and
Suppression diagonal crack produces and the ability of development.
The grid form of reinforcement prestressed concrete quadrate shape pile tube simple structure of the present embodiment: general pile tube manufacturer
All can batch machining produce；Drawing materials conveniently: the steel wide material sources that this utility model uses, complete in specifications, it is convenient to buy,
Basis for there being specified level bearing capacity to need selects to provide a kind of new pile-type.
In a word, this novel square pile tube of engineering structure antidetonation, especially its built-in stirrup is grid form of reinforcement, outside
Concrete is high-strength concrete.Vertical bearing capacity is good, when by horizontal loading, netted form of reinforcement compared to
The generation of pile body diagonal crack and the inhibitory action of development are become apparent from by common tie hoop, its bending resistance shear-carrying capacity phase
There is bigger lifting compared with prestressed concrete quadrate shape pile tube, compensate for general prestressed concrete quadrate shape pile tube lateral loading
Hypodynamic shortcoming.
