Description
Technical field
The present invention relates to a kind of pile extension device of the foundation pile in terms of building, especially a kind of resistance to plucking square pile pile extension enhancing dress
It sets.
Background technique
With the development of society, all kinds of building leaps, stronger to basic engineering requirement, and pile body design, pile extension quality,
It is particularly important.Existing uplift pile pile extension mode: there are two types of uplift piles, for circle stake and square pile.Circle stake is the end plate at two
The periphery envelope of joint has connection iron plate, and runs through pile body, joint welding, complex process, operation hardly possible at end plate with peg
Degree is big, and construction cost is high；And the four sides joint that existing square pile is the end plate when two stakings are closed engages and welds, at pile extension
Tension, bending strength design requirement is often not achieved.Solid square pile is industry, civil buildings, bridge, port under normal circumstances
Mouth, water conservancy etc., it is desirable that antidetonation column degree is higher, is the preferred pile foundation for having the low cushion cap foundation of greater level load, is designing two sections
It when the above stake, has higher requirements to the tensile property of stake, pile body will be had to be larger than by specially requiring tension, bending strength at pile extension
Tension, bending strength are 1 point 5 times of pile body, just can ensure that pile foundation quality.
Common square pile during the pile driving process, generally uses more piece stake connection type, usually common welding, and welding grade is wanted
It asks and reaches second level, but in actual operation, irregular because of the electric welding technology and sense of responsibility of operating personnel, welding quality is often
It is not achieved design requirement, and the pile extension quality of uplift pile, it is desirable that it is very high, therefore must separately plus machine on the basis of original welding when pile extension
Tool connection, just can ensure that pile foundation quality meets design requirement.
Summary of the invention
For above-mentioned problem and requirement, the present invention provides a kind of new pile splicing structure, reaches and reinforce pile extension quality, ties
Structure is simple, easy to use.
The technical solution that the present invention solves the problems, such as is: a kind of resistance to plucking square pile pile extension enhancement device, including square pile end plate, special
Sign is: pile extension enhancement device being arranged when upper and lower pile body pile extension, pile extension enhancement device is made of end plate junction piece and groove, groove
It is arranged on four faces of square pile end plate, end plate junction piece both ends are equipped with pin, and two pins are embedded in pair of pile extension end plate respectively
In the groove answered.
Groove on square pile end plate face is rectangle, and slot body is perpendicular to square pile end plate face.
Groove plug surface and slot bottom angle are less than or equal to 90 °.
Pin is vertical with end plate junction piece body, and pin inner face and block body angle are less than or equal to 90 °.
End plate junction piece is steel-casting or steel plate forging and forming part.
End plate junction piece pin rounding of angle.
New resistance to plucking square pile pile extension: the gap between four faces of end plate joint is welded engagement first, then pile extension is installed
Two pins of end plate junction piece are inlaid into the corresponding groove of pile extension end plate by enhancement device respectively.
Of the invention has the advantages that, it is ensured that reaches and reinforce pile extension quality, the tension, bending strength at pile extension are stake
For the one point five of the intensity of body again to two times, structure is simple, easy to use.

Specific embodiment
A kind of resistance to plucking square pile pile extension enhancement device, including square pile end plate 4,5, it is characterized in that: when upper and lower pile body 1,6 pile extension
Pile extension enhancement device is set, and pile extension enhancement device is made of end plate junction piece 2 and groove 3,7, and groove 3,7 is arranged in square pile end plate
4, on 5 four faces, 2 both ends of end plate junction piece are equipped with pin 10,15, and two pins 10,15 are embedded in pile extension end plate 4,5 respectively
In corresponding groove 3,7.
Groove 3,7 on square pile end plate 4,5 faces is rectangle, and slot body is perpendicular to end plate face.
Groove plug surface 13 and 11 angle R of slot bottom are less than or equal to 90 °.
Pin 10,15 is vertical with 2 body of end plate junction piece, and pin inner face and block body angle T are less than or equal to 90 °.
End plate junction piece 2 is steel-casting or steel plate forging and forming part.
2 pin angle of end plate junction piece, 16 rounding.
New resistance to plucking square pile pile extension: it first by the electric welding engagement of gap 89 between four faces of end plate joint, then installs and connects
Stake enhancement device, two pins 10,15 of end plate junction piece 2 are inlaid into respectively in the corresponding groove 3,7 of pile extension end plate 4,5.
