On clamp spring, the clamp spring includes being spirally connected end and locking end, and locking end includes the card of one group of arc, and the card is integral into sky
Heart truncated cone-shaped；The plug division of the connector has ramp shaped head and circular platform type plug division.
One side according to the present utility model, the connector accommodate tight lock part to be formed at tensioning attaching nut's inner circumferential
Locking slot；The plug division of the connector includes shank and locking head；The shank is integrally cylindric in hollow reducing,
It is gradually reduced along external thread part to the direction of locking head, the diameter of hollow reducing cylinder；The locking head it is ramp-like；Grafting
Bar and locking head are uniformly provided with several cutting seams；Shank and locking head adjacent form locking groove.
The plug division of one side according to the present utility model, the clamp spring and connector is made of 65Mn steel.It is described
Locking slot has the redundancy cavity of preliminary dimension.
Compared with prior art, the beneficial effects of the utility model include：General 5 minutes connection finish can injection,
Improve work efficiency；Meet specification uplift pile requirement, it is unrestricted；It will not occur due to hammering frequency is high weld seam to be caused to break and hammer into shape
Hit the accident that tensile stress causes weld seam drawing crack；It can avoid due to limitation piling rate stake floating being caused to cause weld cracking；Machinery
Bending resistance, fracture resistance are high；It solves in high temperature, cold season work load, and ensures the quality of connector；It solves because foundation pit is opened
Dig and caused by weld cracking, weld seam of disputing over trifles for spot welding, solder skip etc. not as the problem of；Epoxy drip is applied after solving weld seam cooling
The ancestors such as green grass or young crops paint.

Specific embodiment
As shown in Fig. 1 a to Fig. 1 e, the embodiment one of the utility model is described, which specifically wraps
Include tensioning attaching nut 1 and connector 2.It can be seen that the shape of the tensioning attaching nut on adjacent pile pile is the same,
Therefore the cost of manufacture of nut can be saved, while in pile sinking and pile extension, without the end direction for considering pile body.For opening
Attaching nut is drawn, specifically includes reinforcing bar pier nose fixed part 11, connector accommodates tight lock part 12 and connector spiro union portion 13.Connection
Implement body includes external thread part 21, shank 22 and locking head 23.Shank and locking head are divided into multiple shapes by cutting seam 24
The identical or essentially identical unit of shape.External thread part has the threaded area 21a of predefined parameter.
In this embodiment, connector body is made by 65Mn steel, with elasticity required in engineering.Tensioning connects spiral shell
Female inside has the accommodating space being relatively large in diameter, and forms a locking slot, and the protrusion of the locking groove edge is raised as block, when
When connector is plugged in tensioning attaching nut, the plug division of connector is formed a fixed connection by block protrusion /V.Connector
Through adjacent tensioning attaching nut connector threaded joints when, plug division becomes smaller to contract, diameter, after passage,
Plug division is sprung back, and diameter becomes larger, and so as to depart from from tensioning attaching nut, is formed a fixed connection.
In this embodiment, connector, which accommodates tight lock part, has the redundant space of preliminary dimension, which is used for ruler
The very little reinforcing bar pier nose varied slightly can be dissolved in wherein.Give plug division certain redundant space simultaneously.Cutting seam quantity for 3 to
8, width is 3mm or so.By the design of size, disclosure satisfy that plug division is shunk and the needs of rebound so that installation and
Connection can be met the requirements.
As shown in Fig. 2 a to Fig. 2 e, which specifically includes tensioning attaching nut 201, connector
