Preferably, the connecting plate width is 50mm~150mm, and length is 100mm~600mm, thickness be 5mm~
30mm。
Preferably, one end of the steel pipe is connected with ring flange.
Preferably, the thickness of the steel pipe is 4mm~20mm.
Preferably, the side wall of the steel pipe is provided with through hole.
Preferably, anchor rib is provided with the concrete-pile, anchor hole is provided with the ring flange；The anchor hole is
Threaded through hole is to be provided with the through hole of chuck or to be provided with the through hole that chuck combines with screw thread.
Preferably, the anchor rib uses prestressed steel bar or regular reinforcement.
The beneficial effects of the utility model are：
1st, due to being connected jointly using connecting plate and steel pipe, ring flange, the bending resistance of pile body joint can be increased substantially
Performance, the anti-bending strength and pile body equal strength of joint are realized, live manpower and construction cost can be greatly lowered, shortens construction week
Phase, the problem of bored concrete pile of cast in situs can be avoided to exist.
2nd, the WELDING STUDS set can improve the cohesive force of steel pipe and pile concrete, avoid joint by it is curved when, concrete
There is break-off with ring flange, effectively improve the anti-bending strength of joint.
3rd, the setting of steel pipe can efficiently reduce the stress concentration phenomenon at end plate, can improve the anti-bending strength of joint.Steel
The side wall of pipe sets radial direction through hole to improve the cohesive force of steel pipe and concrete, prevent joint during by horizontal bearing capacity with
Flange disk detachment.
4th, compared with existing anchor rib set-up mode, the utility model on ring flange by setting special anchoring
Hole, while be arranged on high-strength prestressed steel bar as anchor rib on ring flange, it can be achieved when cage bar uses prestressed steel bar
When, anchor rib can share the stress of a part of original cage bar heading, improve the anti-bending strength of joint.
