Description
Technical field
The present invention relates to pile detection field, is specially a kind of foundation pile resistance to plucking detection bearing.
Background technology
Traditional reinforcement welding pullout tests are without specific aim special equipment, only with one jack of a crossbeam, on jack
One block of steel plate is placed, with the U-shaped reinforcement welding exposed across jack and stake end downwards of more single u-shaped reinforcing bars (per single u-shaped reinforcing bar
2 pile end bars of each connection), drive steel plate jacking to pull U-shaped steel muscle by the jacking of jack, because of U-shaped steel muscle and reinforcing bar
It is welded to connect in advance with stake end bar, so stake end bar receives pull force calculation.Shortcoming is：Reinforcing bar can not individually adjust cause
Make that every reinforcing steel bar bear is uneven, freezing makes that the change of reinforcing bar material reduces original mechanical performance, equipment can not fix effectively safely
Hidden danger is big, inefficiency.
Traditional its drawback of reinforcement welding resistance to plucking is：(1) on single girder steel place a jack worker weld below it is U-shaped
Reinforcing bar security risk is too high, and (2) U-shaped steel muscle welds under the conditions of belonging to natural torsion, can not ensure that every reinforcing steel bar bear is uniform, than
The reinforcing bar for such as doing 1000KN pullout tests while stress is 10, wherein have the relatively tighter stress at first of 2 single u-shaped muscle connection, remaining
Relaxation of steel not at the same time stress, then 4 reinforcing bars of first stress because breaking can not bearing the power of 1000KN, after breaking remaining
6 reinforcing steel bar bears but equally also can not bear 1000KN pulling force and the equipment that breaks drops, cause test failure equipment to be damaged with
And surrounding test personnel are formed with larger security threat.(3) welding changes reinforcing bar material to cause material to become fragile drop because freezing
The low original mechanical performance of reinforcing bar, (4) welding efficiency is low, welds the calculation of 5 single u-shaped muscle on demand, then following 10 steel bar weldings
1 day time will be welded by meeting a worker, because every bar bending and the inconsistent welder of slackness will adjust every reinforcing bar and try one's best
Unanimously, operate that not only efficiency substantially reduces but also there are larger in the case where top jack and steel plate are without effectively fixed dangerous situation
Security risk.
The content of the invention
In view of the above problems, the present invention provides a kind of foundation pile resistance to plucking to detect bearing, security risk can be removed, improves examination
Success rate is tested, improves work efficiency；Can effectively it solve the problems, such as in background technology.
To achieve the above object, the present invention provides following technical solution：A kind of foundation pile resistance to plucking detects bearing, including girder steel and
Jack, the jack are fixed at the top of girder steel, and the girder steel and the jack are both provided with two；
Further include
Resistance to plucking bearing, the resistance to plucking bearing are fixedly mounted on the upper end of two jack, and the both ends bottom of resistance to plucking bearing
It is fixedly linked respectively with corresponding jack upper end；
Pull rod, the pull rod lower end are connected with self-locking connector through resistance to plucking bearing, and pull rod upper end can pass through pull-rod nut
It is fixed on resistance to plucking holder top；
Pile body, the pile body upper end are fixed with reinforcing bar, and the reinforcing bar can be attached by self-locking connector and pull rod.
As a kind of preferable technical solution of the present invention, the self-locking connector bottom is consolidated by fixture and reinforcing bar
It is fixed.
As a kind of preferable technical solution of the present invention, the reinforcing bar is both provided with multiple, and pull rod and reinforcing bar with pull rod
Between match one by one.
As a kind of preferable technical solution of the present invention, the pull-rod nut can be to the height and pull rod and resistance to plucking branch of pull rod
The elasticity of seat, which is adjusted, makes every reinforcing steel bar bear relatively uniform.
As a kind of preferable technical solution of the present invention, pass through two supporting legs and corresponding steel before and after the resistance to plucking bearing
Beam is fixed.
As a kind of preferable technical solution of the present invention, the supporting leg passes through the supporting leg fixed frame and resistance to plucking on resistance to plucking bearing
Bearing is fixed.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) traditional experiment device without effective fixed and U-shaped muscle flexural deformation and is needed to weld the big installation of gap and used because of equipment
When 8-9 it is small when, the present invention because equipment consolidate safety, pull rod can adjust and there is no flexural deformation, need not weld so pacifying
Dress only need 2 it is small when.
(2) the U-shaped muscle of traditional experiment device influences not stretching by machinery by bending, and artificially stretching makes every reinforcing steel bar bear
Error is 100-300KN, and stress error is only that 1-3KN success rates greatly improve between every reinforcing bar of the invention.
(3) conventional apparatus by welding influenced reinforcing bar material become fragile mechanical performance reduce pulling force substantially reduce in loading process
It is easy to break, the present invention with mechanical self-latching mode connects 100% and maintains the original mechanical performance success rate of reinforcing bar to be carried significantly
It is high.
(4) traditional experiment device single-beam list top, jack top, which is placed, thickeies the very poor security risk of steel plate stabilization of equipment performance
Greatly increase, place resistance to plucking bearing above twin beams Double Tops jack of the present invention, resistance to plucking bearing corner install adjustable supporting leg with
Lower section girder steel connective stability height greatly improves safety coefficient.
