It is a screw in the middle of the connection box top, for connecting the sleeve；The connection box lower central is punching
Hole, for connecting prefabricated pile reinforcing bar end upset；The connection box side be through square hole, have in the square hole two it is positioned opposite
Clamp, the opposite face of the clamp is semi-circular arc face, and the semi-circular arc face is provided with dimpled grain, in the clamp
The back side is provided with spring members, and the square hole is externally provided with cover plate so that the spring members are located in the square hole；
One end that the connecting pin is used to connect the sleeve has screw thread；The connecting pin is used to connect the connection box
One end there is burr, be engaged with the dimpled grain on the semi-circular arc face of the clamp.
Further, the burr of described connecting pin one end is latch, the axle of each tooth of the latch in the connecting pin
To the rectangular isosceles triangle of projection on tangent plane, and hypotenuse is towards the non-threaded end of the connecting pin；The semicircle of the clamp
Projection rectangular isosceles triangle of each concave tooth of dimpled grain on arc surface in the axial slices of the clamp, with the company
The latch of pin is engaged.
The advantage of the invention is that:Present invention efficiently solves prestressed-concrete pile link cost is high, quality is easily received
Artificial and such environmental effects, particularly steel joint directly contact perishable problem with external environment.Inventive joint is filled
Put without using termination steel end plate, piecing devices allow the presstressed reinforcing steel of upper and lower two sections stake to be docking together, and resistance to plucking effect is good；This
In invention piecing devices are wrapped in by pile concrete, steel member, without directly contact, efficiently solves pile joint and prevents with the external world
The technical barrier of corrosion, and joint is easy to process, using simple to operate, the quality to prefabricated pile basis plays promotion well；
Particularly its corrosion resistance has positive effect to ensureing construction engineering quality.
【Brief description of the drawings】
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is structural representation of the invention.
Fig. 2 is connecting pin structural representation of the invention.
【Specific embodiment】
As depicted in figs. 1 and 2, a kind of prestressed concrete prefabricated pile mechanical splice device, including sleeve 1, connection box 2,
Connecting pin 3.
The sleeve 1 is connected to a prefabricated pile reinforcing bar end upset, and the connection box 2 is connected to another prefabricated pile reinforcing bar end upset.
One end of the connecting pin 3 connects the sleeve 1, the other end connection connection box 2.
The one end of the sleeve 1 has an aperture 11, for inserting reinforcing bar；The other end of the sleeve 1 has a macropore 12, institute
Stating the inwall of macropore 12 has screw thread, the one end for connecting the connecting pin 3.
It is a screw 21 in the middle of connection box 2 top, for connecting the sleeve；The connection box lower central is to wear
Heart hole 22, for connecting prefabricated pile reinforcing bar end upset；Connection box 2 side be through square hole 23, have two in the square hole 23
Individual clamp 24 positioned opposite, the opposite face of the clamp is semi-circular arc face, and the semi-circular arc face is provided with latch
241, spring members 25 are provided with the back side of the clamp 24, the square hole 23 is externally provided with cover plate 26 so that the spring members
25 are located in the square hole 23.
One end that the connecting pin 3 is used to connect the sleeve 1 has screw thread 31；The connecting pin 3 is used to connect described
The one end for connecting box 2 has latch 32, is engaged with the latch 241 on the semi-circular arc face of the clamp 24.
Projection rectangular isosceles triangle of each tooth of latch 32 in the axial slices of connecting pin 3, and hypotenuse is towards even
The non-threaded end of pin 3；Each concave tooth of latch 241 on the semi-circular arc face of clamp 24 is in the axial slices of clamp 24
The rectangular isosceles triangle of projection, be engaged with latch 32.
Make prefabricated pile when, the headgear of presstressed reinforcing steel one enter sleeve 1, other end be inserted in connection box 2 carry out again heading, compile cage
(prefabricated pile be pile jacking when, can two ends use sleeve).During prestressed stretch-draw, the prestress anchoraging screw at stake two ends is locked in respectively
In the screw of sleeve 1 and connection box 2.Concrete reach put symmetrical dismounting prestress anchoraging screw after Zhang Qiangdu realize it is prestressed
Put and open.The one end of box 2 is connected during piling construction upwards, when lower stake top portion pile sinking is to about 1 meter above ground level, upper stake (sleeve 1 of slinging
End is downward, and connecting pin 3 is tightened on sleeve 1 in advance, is applied in two end faces and spreads fast hard epoxy resin or similar preserving timber
Material, the alignment connection screw of box 2 of connecting pin 3, puts down stake, and connecting pin 3 is pressed into the clamp 24 of connection box 2 using stake deadweight
Between, the latch 241 of clamp 24 can mutually be clasped with the latch 32 of connecting pin 3 under the ejection force of spring 25.Prestressing force is completed to mix
