Description
Technical field
The present invention relates to the counter-force pulling device in single-pile vertical orientation static test, especially relate to adjustable nodel line bar and connect
Device.
Background technology
During civil construction, the purpose of single-pile vertical orientation static test is to provide reference frame or inspection for Pile Foundations Design
The pile quality of engineering pile, single-pile vertical orientation static test must have the loading counterforce device of provided counter-force.Chinese invention is (specially
Profit number: ZL201320716270.3) disclosing one " single-pile vertical orientation static test counter-force pulling device ", this device is by being connected to
Many finish rolling deformed bars between two pre-anchors and steel strand wires composition tractive structure, it is adaptable to large-tonnage, the list of super-tonnage
Stake Vertical Static Loading Test.Relative to test loading force, steel strand wires pull-off force is less, during single-pile vertical orientation static test, due to
Many steel strand wires even all continuous tensile phenomena of steel strand wires that a piece steel strand wires unbalance stress causes, will cause the mistake of test
Lose, therefore in this counter-force pulling device, the uniform force degree of steel strand wires becomes key factor.When steel strand wires use traditional can not
When regulation line rod connector is connected with the finish rolling deformed bar being embedded in anchoring pile stake top, it is impossible to enough regulation steel strand wires rates of tension, make
Become the unbalance stress during steel strand experiment.
Summary of the invention
Present invention aim at providing a kind of adjustable nodel line rod connector.
For achieving the above object, the present invention takes following technical proposals:
Adjustable nodel line rod connector of the present invention, including adjusting rod, branch sleeve and union joint；Described branch sleeve is relative
Offering perforation on the barrel of nozzle, described union joint is Step Shaft structure, and the larger diameter end of union joint is positioned at described connection
In sleeve, smaller diameter end is outside branch sleeve is extended in described perforation；Described adjusting rod outer peripheral face offers left hand thread also
With branch sleeve inwall bolt；Be positioned at the adjusting rod end outside branch sleeve offer for fining twisted steel bolt
Right-handed thread hole；Extend the union joint outer peripheral face outside branch sleeve offer left hand thread and be bolted with anchoring ring set；
The endoporus of described anchoring ring set is made up of cylindrical hole section and round platform hole section, is provided with intermediate plate, is positioned at cylinder in the section of described round platform hole
It is provided with spiral compression spring in the section of hole.
Described intermediate plate is three-chip type steel strand wires anchoring clamping piece, and the end face of described union joint smaller diameter end offers blind hole.
The outer surface of described branch sleeve and anchoring ring set is anti-skidding matsurface.
The invention has the advantages that guarantee whole steel strand wires uniform force in single-pile vertical orientation static test；During use, logical
Cross the present invention to be connected with the finish rolling deformed bar being embedded in anchoring pile stake top by steel strand wires, by regulation branch sleeve and anchoring ring
Set, reaches the purpose of initial adjustment steel strand wires tensioning degree.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it is shown in figure 1, adjustable nodel line rod connector of the present invention, including adjusting rod 1, branch sleeve 2 and union joint；
Described branch sleeve 2 is relative to offering perforation on the barrel of nozzle, described union joint is Step Shaft structure, union joint big straight
Footpath end 3.1 is positioned at branch sleeve 2 and smaller diameter end 3.2 is outside branch sleeve 2 is extended in described perforation；Described adjusting rod 1
Outer peripheral face offer left hand thread and with branch sleeve 2 inwall bolt；It is positioned at adjusting rod 1 end outside branch sleeve 2 to open
It is provided with for the right-handed thread hole 5 with fining twisted steel 4 bolt；Extend the union joint smaller diameter end outside branch sleeve 2
3.2 outer peripheral faces offer left hand thread and are bolted with anchoring ring set 6；The endoporus of described anchoring ring set 6 is by cylindrical hole section and round platform
Hole section is constituted, and is provided with three-chip type steel strand wires anchoring clamping piece 7, is positioned at cylindrical hole section and is provided with helical compression in the section of described round platform hole
Spring 8, offers blind hole 9 on the end face of union joint smaller diameter end 3.2, and the diameter of described blind hole 9 is more than steel strand wires 10 diameter；
In order to skid when preventing from regulating, the outer surface of branch sleeve 2 and anchoring ring set 6 is anti-skidding matsurface.
Operation principle of the present invention is summarized as follows:
During use, steel strand wires 10 are fixed in the round platform hole section of anchoring ring set 6 by three-chip type steel strand wires anchoring clamping piece 7, will put
Put the larger diameter end 3.1 of union joint in branch sleeve 2, offer left-handed spiral shell by union joint smaller diameter end 3.2 outer peripheral face
Stricture of vagina and spiral compression spring 8 screw, and prevent three-chip type steel strand wires anchoring clamping piece 7 from loosening, and branch sleeve 2 other end passes through left hand thread
Being connected with adjusting rod 1, the right-handed thread hole 5 being opened on adjusting rod 1 is connected with finish rolling deformed bar 4.Adjusting rod 1 is relative to essence
Rolling screw-thread steel 4 when turning clockwise, fining twisted steel 4 is drawn close to adjusting rod 1, precession in the right-handed thread hole 5 of adjusting rod 1,
Adjusting rod 1 is now to rotate counterclockwise relative to branch sleeve 2, and by left hand thread, branch sleeve 2 is drawn close to adjusting rod 1, will
Adjusting rod 1 precession in branch sleeve 2, reaches the purpose of tensioning steel strand wires 10.In like manner, adjusting rod 1 is relative to fining twisted steel 4
When rotating counterclockwise, reach the purpose of locking steel strand wires 10.
