Description
Technical field
This utility model is related to a kind of foundation detection means, more particularly to a kind of single pile static load pulling resistance testing device.
Background technology
Static load of pile foundation measuring technology is that the use with pile foundation in architectural design more and more extensively grows up.
At present, static test is that bearing capacity of single pile is most directly perceived, most reliable method for detection.The purpose of single pile static load pullout tests is to adopt
Close to the test method of the actual operating conditions of vertically pulling-resistant stake, the vertical ultimate uplift resistance of single pile of test pile is determined.Mesh
Front main static-load testing device is as follows：Exposing including top has the tested single pile of several vertical applied force reinforcing bars, balanced configuration
In the left and right vertical reference stake of the recessed lower in the subsoil ground of tested single pile both sides compacting, left and right benchmark is symmetrically set up in
Left and right horizontal reference beam in stake, left and right displacement meter of the balanced configuration between tested single pile both sides and left and right datum line beam,
Left and right buttress of the balanced configuration on the subsoil ground of the compacting of tested single pile both sides, is set up at the top of left and right buttress
Girder steel, top board and steel bar stress above the test hydraulic jack being configured above girder steel midpoint and connection jack
Force transmission mechanism.In test, jack provides very strong pulling capacity can to steel bar stress, thus force transmission mechanism and steel bar stress it
Between bonding strength should disclosure satisfy that the requirement of test.General force transmission mechanism is welding or anchor with the connected mode of reinforcing bar
Connect, complex procedures waste time and energy, and the intensity of pad is easily affected by welding procedure, cause load not enough.
Authorization Notice No. is CN204875887U, the Chinese patent that authorized announcement date is on December 16th, 2015 discloses one
Unit for single-pile vertical anti-pulling static test attachment means are planted, including connecting plate and the locking plate on connecting plate, the connecting plate bag
The first face and the second face opposite with the first face is included, the least one set in first face and the second face on connecting plate, is formed through
Lockhole, every group of lockhole include that side wall surrounds the first lockhole of taper type and at least one second lockholes；First lockhole is in the first face
The size for being smaller in size than its opening for being formed on the second surface of the opening of upper formation；Described at least one second lockholes are first
Size of the size of the opening formed on face more than its opening for being formed on the second surface；Separable in each lockhole it is provided with two
The locking plate of block or more, the outer circumferential side of described two pieces or more of locking plate are relative with lockhole inwall, surround as taper type, inner circumferential side
The hole of about one consistent size is surrounded, both sides are affixed with adjacent locking plate side.It is formed with and which on the wall of the locking plate inner circumferential side
The perpendicular heaving of the sea shape lines of the short transverse of surrounded frustum or screw thread.Between each lockhole inwall and the locking plate also
It is provided with a hollow frustum and fixes chuck, the outer peripheral sidewall of the chuck is affixed with lockhole inwall, its inner circumferential side wall and lock
Piece outer peripheral sidewall is affixed.
It is in place of the deficiencies in the prior art, the locking plate of the utility model is independent mutually, when mounted, needs first handle
Locking plate pulls out a part from lockhole, just disconnected from each other between locking plate when pulling out, again by locking plate after insertion reinforcing bar
Lockhole is put back to, now it is difficult to ensure that sustained height is between locking plate, that is to say, that be difficult to ensure that reinforcing bar is in the center of lockhole
Between position, can make cage bar unbalance stress and make measured displacement data inaccurate.And due to independent mutually between locking plate, peace
Needing with hand rest always when when dress, lower surface opening adjusts height more than the locking plate in the lockhole of upper surface open prevents
Which drops, hence it is evident that increased the complexity of installation.
Utility model content
