Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It referring to Fig.1, is a kind of uplift pile pile extension connecting node disclosed by the utility model, including upper section stake 1 and lower section stake
2.Uplift pile can be various forms of concrete-piles, and the uplift pile in the present embodiment is cylindrical.In uplift pile work progress
In, if pile foundation is deeper, it is necessary to be docked to multiple uplift piles, upper section stake 1 and lower section stake 2 are picked up to come.First will when construction
Soil is squeezed into lower section stake 2, exposes a part outside soil for connection.The bottom surface of upper section stake 1 is connected with end plate 1, lower section stake 2
Top surface be connected with end plate 2 21, end plate 1 and end plate 2 21 are welded, the preliminary of stake 1 and lower section stake 2 is saved in realization
Connection.The top of lower section stake 2 is also arranged with connecting tube 3, and the internal diameter of connecting tube 3 is equal to the diameter of lower section stake 2.Connecting tube 3 is protected
The weld of end plate 1 and end plate 2 21 avoids underground water corrosion failure weld.
Referring to Fig.1 with Fig. 2, connecting tube 3 further connect by fastener with lower section stake 2.Fastener includes bolt 4 and spiral shell
Hole 41.Connecting tube 3 is equipped with bolt 4 on the circumferential side wall of lower section stake 2, and bolt 4 is circumferentially equidistant to be arranged at intervals with four.Under
Save the screw hole 41 for offering on the circumferential side wall of stake 2 and cooperating with bolt 4.Connecting tube 3 is also worn on the circumferential side wall of upper section stake 1
Equipped with bolt 4, bolt 4 is circumferentially equidistant to be arranged at intervals with four.It is offered on the circumferential side wall of upper section stake 1 and the cooperation of bolt 4
Screw hole 41.By the cooperation of bolt 4 and screw hole 41, so that 3 lock ring of connecting tube lives in save stake 1 and lower section stake 2, to make section stake
1 connect stronger extraction-resistant behavior at raising connecting node with lower section stake 2.
Referring to Fig.1 with Fig. 2, be equipped with tension rib 5 in connecting tube 3, tension rib 5 through connecting tube 3 top and bottom and
Perpendicular to 3 top surface of connecting tube, tension rib 5 is circumferentially equidistant to be arranged at intervals with several.The both ends that tension rib 5 stretches out connecting tube 3 are equal
It is arranged in bending, the annulus 51 with the cooperation of 5 bottom end of tension rib, the circumference of upper section stake 1 is welded on the circumferential side wall of lower section stake 2
The annulus 51 with the cooperation of 5 top of tension rib is welded on wall.After 3 lock ring of connecting tube lives in save stake 1 and lower section stake 2, by tension rib 5
Bottom end bending after be caught in the annulus 51 in lower section stake 2, the annulus 51 of upper section stake 1 will be caught in after the tip flexion of tension rib 5
It is interior.When upper section stake 1 is by upward buoyancy, tension rib 5 has the tendency that rising with upper section stake 1, on lower 2 circumferential side wall of section stake
Annulus 51 limit tension rib 5 rise, thus limitation on save stake 1 rising so that upper section stake 1 connect with lower section stake 2 it is more secured.
Referring to Fig. 3 and Fig. 4, it is symmetrical arranged on the circumferential side wall of connecting tube 3 there are two anti-floating column 6, anti-floating column 6 is threadedly coupled
In connecting tube 3.The one end of anti-floating column 6 far from connecting tube 3 diagonally downward and is additionally provided with pointed cone portion 61.Pointed cone portion 61 can make anti-floating
Column 6 is more easily inserted into soil, reduces the aeration level of soil so that soil be bonded with anti-floating column 6 it is closer.Anti-floating column 6
Side also set up flight 7, after flight 7 is inserted into soil, the soil of 7 top of flight stops flight 7 to move up, and makes
Anti-floating column 6 is not easy to extract upwards, so that stake 1 and lower section stake 2 are saved on constraining together with connecting tube 3, so that upper section stake 1 and lower section stake
2 connections are stronger, improve the extraction-resistant behavior at connecting node.
The implementation principle of the present embodiment are as follows: first by lower 2 a part embedment underground of section stake, top a part exposes soil
For subsequent pile extension.Upper section stake 1 is lifted to the surface of lower section stake 2 again and is then put down, end plate 1 and end plate 2 21 are welded
Get up, the preliminary connection of stake 1 and lower section stake 2 is saved in realization.
Upper connector 3 is covered in weld again, the weld of end plate 1 and end plate 2 21 is protected by connecting tube 3, is avoided
Underground water corrosion failure weld.Screwing bolts 4, by the cooperation of bolt 4 and screw hole 41, so that 3 lock ring of connecting tube lives in section
Stake 1 and lower section stake 2 improve the extraction-resistant behavior at connecting node so that it is stronger to connect section stake 1 with lower section stake 2.
Then, annulus 51 is welded on the circumferential side wall of upper section stake 1 and lower section stake 2 respectively, using tool by tension rib 5
It is caught in the annulus 51 in lower section stake 2, will be caught in after the tip flexion of tension rib 5 in the annulus 51 of upper section stake 1 after the bending of bottom end.
When upper section stake 1 is by upward buoyancy, tension rib 5 has the tendency that rising with upper section stake 1, the circle on lower 2 circumferential side wall of section stake
Ring 51 limit tension rib 5 rise, thus limitation on save stake 1 rising so that upper section stake 1 connect with lower section stake 2 it is more secured.
Finally, upper section stake 1 is pressed into soil with lower section stake 2 by hydraulic device again.During this, 3 circumference of connecting tube
Anti-floating column 6 on wall is also inserted into soil.When upper section stake 1 is by upward buoyancy, soil generates straight down anti-floating column 6
Pressure prevents section stake 1 from floating, so that upper section stake 1 connect more secured resistance to plucking at raising connecting node with lower section stake 2
Energy.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
