Abstract
The utility model discloses a kind of connectors for prefabricated pile, and including connector body, the connector body includes threaded joints, grafting bar portion and locking head；The threaded joints are provided with external screw thread；The grafting bar portion is integrally cylindric in hollow reducing, and threadingly connecting portion to the direction for locking head, the diameter of hollow reducing cylinder is gradually reduced；It is described to lock the ramp-like of head；Grafting bar portion and locking head are uniformly provided with several cutting seams；Grafting bar portion and locking head adjacent form locking groove.When in use, the threaded portion of the connector is attached with being laid in the tensioning nut of prefabricated pile end, locking head is plugged in the tensioning nut of another prefabricated pile end, you can locks adjacent prefabricated pile.Speed of application is faster and quality of connection is more preferable.
Description
Technical field
The utility model belongs to pile pile field, in particular for the device of the fixed pile pile of connection.
Background technology
Pile pile has bearing capacity of single pile height, low cost and construction adaptable to the geological conditions of supporting course fluctuations
Fireballing feature, the extensive use in architectural engineering.Due to the limitation of traffic condition, the length of pile pile is generally 10 to 15
Rice, site operation often want pile extension.Existing pile extension mode mainly has end plate Jointing, is bonded pile extension and mechanical connection connects
Stake.Wherein, mechanical connection pile extension mainly using spring-gripping type connect, spring easily fails, and requirement on machining accuracy is higher, make and
The difficulty of construction compares larger.
Utility model content
In order to solve the above problem of the existing technology, a kind of connector for prefabricated pile is provided, to improve pile pile
The mechanical property that the efficiency of pile extension is connected with pile pile.
Technical solution：A kind of connector for prefabricated pile, including connector body, the connector body includes screw thread
Connecting portion, grafting bar portion and locking head；The threaded joints are provided with external screw thread；The grafting bar portion is in integrally hollow change
Diameter is cylindric, and threadingly connecting portion to the direction for locking head, the diameter of hollow reducing cylinder is gradually reduced；The locking head
It is ramp-like；Grafting bar portion and locking head are uniformly provided with several cutting seams；Grafting bar portion and locking head adjacent shape
Into locking groove.
One side according to the present utility model, the cutting seam is 3 to 8.The material of the connector body is
65Mn steel.The junction on the grafting bar portion and locking head is arc, and radius is 0.8 to 2.0mm.The threaded joints
With grafting bar portion junction with the non-threaded area that a width is 1.5 to 2.5mm.The outer diameter of one end of the grafting bar portion is 14
To 18mm, one end is 10 to 12mm.
Advantageous effect：When in use, the threaded portion of the connector is carried out with being laid in the tensioning nut of prefabricated pile end
Connection, locking head are plugged in the tensioning nut of another prefabricated pile end, you can lock adjacent prefabricated pile.Speed of application is more
Fast and quality of connection is more preferable.

Specific embodiment
As depicted in figs. 1 and 2, the connector for prefabricated pile of the utility model, including connector body.Along connector
One end of ontology is followed successively by threaded joints 3, grafting bar portion 2 and locking head 1, three part one to the direction of the other end
Molding.In the periphery of threaded joints, external screw thread 32 is provided with, there is non-threaded area between threaded joints and grafting bar portion 2
31 .Grafting bar portion is cylindric for hollow reducing, and diameter is tapered into from threaded joints to the direction on locking head.Grafting
There are several cuttings to stitch 21 for bar portion and locking head, be divided into the identical or essentially identical multiple lists of several shape designs
Member.Head is locked in ramp shaped, in order to be plugged in nut.The adjacent for locking head and grafting bar portion forms locking groove.
Head and the shape of grafting bar portion are locked, connector integrally has there are one the locking region of wedge shape, can be with being fixed on prefabricated pile
The nut of end is locked, so as to achieve the purpose that be fixedly connected.
As shown in Figure 3 and Figure 4, cutting seam is 3 to 8, and cutting seam is 3mm wide.In this embodiment, preferably 8.Even
The material for connecing device ontology is 65Mn steel, and the steel elasticity of the model is preferable, after connector is connect with nut, grafting bar portion and locking
Head is sprung back, so as to the fixed locking of the two.The junction on grafting bar portion and locking head is arc, and radius is 0.8 to 2.0mm,
Form a wedge-shaped groove, the connection and locking even closer with attaching nut.Threaded joints and grafting bar portion junction
With the non-threaded area that a width is 1.5 to 2.5mm.The outer diameter of one end of grafting bar portion be 14 to 18mm, one end for 10 to
12mm has found that the design of the reducing ratio, compression and the effect sprung back are very good, disclosure satisfy that the need of engineering in an experiment
It will.
The preferred embodiment of the utility model, still, the utility model and unlimited are described in detail above in association with attached drawing
Detail in the above embodiment, can be to the skill of the utility model in the range of the technology design of the utility model
Art scheme carries out a variety of equivalents, these equivalents belong to the scope of protection of the utility model.
