The specific embodiment:
The present invention includes pile tube; It is characterized in that: pile tube both ends endoporus is provided with the external port step taper hole littler than circular diameter of the interior end, and other is provided with by two reamer circles 4, two reamer plugs 6, two linkages that fan-shaped awl poppet, double threaded screw, locking rotating disk 3 are formed; Reamer circle 4 is body in a tubular form, is uniformly distributed with several axial strip grooves on the tubular body, and the tubular body external diameter is less than pile tube step taper hole external port diameter; Reamer plug 6 is frustum, and the frustum axial height is less than reamer circle 4 axial heights, and the big footpath of frustum cylindrical is less than reamer circle 4 internal diameters, and frustum central authorities are provided with screwed hole, and two frustum screwed hole thread rotary orientations are reverse each other; Fitting on the frustum bigger diameter end face of reamer plug 6 is fixed with the rubber damping ring 7 of coaxial inner conductor, and rubber damping ring 7 external diameters equal end circular diameter in the pile tube step taper hole; The double threaded screw middle part is a short cylinder; Short cylinder two is the reverse each other screw rod corresponding to two reamer plug 6 screwed holes; Locking rotating disk 3 is the annulus plate-like, and the circle ring disk external diameter equals the pile tube external diameter, and locking rotating disk 3 medium pores are linked in double threaded screw middle part short cylinder cylindrical and implement to be fixedly connected; The circle ring disk both ends of the surface are provided with all deep-slotted chip breakers of ring, and the circle ring disk cylindrical is uniformly distributed with some rectangle radial slots; Fan-shaped awl poppet is made up of tray deck and four fan awl pieces 5; Fan awl piece 5 is 1/4 type of tile body that an internal taper forms greater than the even vertically cutting of the hollow frustum of external taper; Four fan frustum miner diameter end end faces respectively are provided with a screwed hole and implement ring Zhou Junbu through bolt and the through hole of the support disk ring Zhou Junbu that is the annulus plate-like and fix; Tray deck medium pore diameter is greater than stud 1 middle part short cylinder external diameter; Bowlder outside tray deck is linked in stud 1 middle part short cylinder, a spacer pin 2 passes the corresponding radial hole of short cylinder and implements fixing; Two root canal piles butt joint initial status structure is: locking rotating disk 3 encircles several balls and the two root canal pile opposing end faces of placing on all deep-slotted chip breakers through the two sides and fits; Two reamer plug 6 paths relatively and twist be combined in the counterparty to the double threaded screw of screw thread on; Circle is linked on reamer plug 6 cylindricals in the fan awl piece 5; The tray deck medium pore is enclosed within stud 1 middle part; Reamer circle 4 interior circles are linked on fan awl piece 5 cylindricals, and reamer circle 4 rectangular slotted openings are end circle in pile tube step taper hole, and two reamer circle 4 cylindricals are enclosed within respectively in the step taper hole of front and back root canal pile; Two pile tube butt joint back status architectures are: reamer circle 4 is the Taper Pipe shape; Its cylindrical compression type is fitted in the pile tube step taper hole; Reamer plug 6 cylindrical compression types are fitted on the fan awl piece 5 interior circles; Fan awl piece 5 cylindrical compression types are fitted in the reamer circle 4 on the circle, and two reamer plug 6 opposing end surface spacings are dwindled but possessed the gap.
Pile tube butt joint previous work is: with reamer the step taper hole is got at the pile tube both ends, or be preset with the step taper hole during tubular pile concrete cast.Fan-shaped awl poppet tray deck medium pore is inserted in from stud 1 two respectively; Then spacer pin 2 being passed the radial hole that stud 1 short cylinder is provided with implements spacing; Again reamer circle 4 is enclosed within and fans awl piece 5 cylindricals, then two reamer plugs 6 are screwed in studs 1, make it and fan awl piece 5, reamer circle 4 generation prestressing force; Be as the criterion can not come off, form a whole package.
During the pile tube butt joint, in the root canal pile port step taper hole, this moment, reamer circle 4 external diameters of whole package below were slightly smaller than pile tube stepped hole port internal diameter, easily were inserted in before whole package was inserted in.Overlap fashionable requirement will be placed in advance before the ball of root canal pile upper surface ring week in the groove of being pressed into locking rotating disk 3 lower surfaces, then encircle all grooves and place ball in locking rotating disk 3 upper surfaces, lifting back root canal pile is inserted in the reamer circle 4 on whole package top again.After suspender loosens, on the root canal pile, then the set lever front end is inserted radial slot corresponding to the plug of locking rotating disk 3 rectangle radial slot shapes before back root canal pile is pressed together on fully, firmly rotation lock rotating disk 3 is locked rotating disk 3 and is driven stud 1 rotation.Because reverse thread forces two reamer plug 6 move toward one another to be drawn close each other, force fan awl piece 5 outer opening, drive reamer circle 4 outer opening.The strip groove that reamer circle 4 is provided with is compelled to be extended to acute angle-shaped opening, and is beneficial to reamer circle 4 and is extended to taper, implements the butt joint of two root canal piles.Can not weld at locking rotating disk 3 places the butt joint back, can do spot welding with the pile tube joint place at locking rotating disk 3 for reinforcing yet.The butt joint time spent shortens dramatically.
Ball is set to be beneficial to when locking rotating disk 3 rotations laborsaving.
It is during for stud 1 rotation that reamer plug 6 bigger diameter ends are provided with rubber damping ring 7, and damping ring 7 and pile tube endoporus and reamer circle 4 end faces, endoporus produce circumferential damping force, make reamer plug 6 not change translation forward.
If fan awl piece 5 is not set, only depend on reamer plug 6 and reamer circle 4, also can implement 6 translations of reamer plug theoretically, but have only reamer plug 6 bigger diameter end portions contact reamer circle 4 during 6 translations of reamer plug, active force is the single-point transmission, and translatory distance is longer.And set up fan awl piece 5, and because male cone (strobilus masculinus) is fitted with reamer plug 6 male cone (strobilus masculinus)s, reamer circle 4 endoporus are basic in advance respectively in it comprehensively, thereby reamer plug 6 is when moving ahead, its active force is the face transmission.Binding face is good, and active force is even, and reamer is effective, and reamer plug 6 moves ahead apart from short.
