Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe pile reinforcement device, and is specifically a steel pipe pile reinforcement device for bridge friction piles. Background Art

[0002] The steel pipe pile is composed of a steel pipe, a tongue and groove groove and a tongue and groove pin. The tongue and groove groove is vertically connected to the pipe wall at the left end of the steel pipe diameter. The cross-section of the tongue and groove groove is a square frame with one side open. Reinforcing ribs are provided on the side of the tongue and groove groove. The tongue and groove pin is vertically connected to the pipe wall at the right end of the steel pipe diameter and at a radial position. The groove section of the tongue and groove pin is I-shaped.

[0003] At present, in the prior art, for example, Chinese patent with announcement number CN215482887U discloses a steel pipe pile reinforcement device, which reinforces the steel pipe through a fixing seat and a connecting piece, so that multiple steel pipe piles are connected into a whole through the connecting piece. However, in the device, the friction pile is not fixed, so that once the friction pile is slightly tilted due to the vibration generated by the passage of vehicles, the steel pipe pile is completely unable to cope with the pressure transfer caused by the tilt of the friction pile. In view of this, we propose a steel pipe pile reinforcement device for bridge friction piles. Utility Model Content

[0004] The main purpose of the utility model is to provide a steel pipe pile reinforcement device for bridge friction piles, which can solve the problems raised in the above-mentioned technical background.

[0005] To achieve the above-mentioned purpose, the utility model proposes a steel pipe pile reinforcement device for a bridge friction pile, comprising a steel pipe pile, a back plate is clamped on the surface of the steel pipe pile, a support block is fixedly connected to the back of the back plate, the inner wall of the support block is slidably connected to a limiting block, and a fastening ring is clamped between the support block and the inner wall of the limiting block.

[0006] Preferably, the inner wall of the back plate is hinged to both sides of the fixing ring, a fixing rod is sleeved on the inner wall of the fixing ring, and a thermal expansion fixing sleeve is sleeved on the surface of the fixing rod. By setting the thermal expansion fixing sleeve, the fixing rod can be limited by the thermal expansion fixing sleeve to prevent the thermal expansion fixing sleeve from falling off during the support process due to the vibration generated by the working process of the bridge, thereby achieving the locking effect of the fixing ring.

[0007] Preferably, the surface of the fixing rod is connected with a clamping ring, the surface of the clamping ring is fixedly connected to the inner wall of one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the inner wall of the fixer.

[0008] Preferably, the inner wall of the fixer is threaded to the surface of the long screw, and the surface of the long screw is threaded to the inner wall of the screw ring.

[0009] Preferably, the front face of the fixing device is interlocked with the surface of the friction pile.

[0010] Preferably, the screw rings are in a group of three, with multiple groups arranged in total, and arranged in a linear array on the surface of the long screw.

[0011] The utility model provides a steel pipe pile reinforcement device for bridge friction piles. Have the following beneficial effects:

[0012] (1) The steel pipe pile reinforcement device of the bridge friction pile can prevent the clamping ring from being fixed by setting a fixing rod and a toothed groove on the fixing rod, so that the angle of the connecting rod can be fixed by the clamping ring. The angle of the connecting rod can be changed by changing the angle of the clamping ring. When the distance between the steel pipe pile and the friction pile is different, the angle of the connecting rod can be changed so that the fixer can always tightly support the friction pile, thereby providing an auxiliary support effect for the friction pile.

[0013] (2) The steel pipe pile reinforcement device of the bridge friction pile can limit the long screw rod by setting a screw ring. When the steel pipe pile is squeezed toward the friction pile due to excessive pressure from the bridge, the steel pipe pile squeezes the fixer through the connecting rod, and the long screw rod and the screw ring can limit the fixer, thereby preventing the fixer from being displaced, thereby protecting the fixing rod from being worn by the clamping ring, thereby preventing the fixing rod from losing the limit of the clamping ring, and making the fixing effect of the device better.

[0022] In the example process of the utility model, the inner wall of the fixing ring 7 is sleeved with a fixing rod 8. The fixing rod 8 is set, and the toothed groove on the fixing rod 8 can prevent the clamping ring 10 from being fixed, so that the angle of the connecting rod 11 is fixed by the clamping ring 10. By changing the angle of the clamping ring 10, the angle of the connecting rod 11 can be changed. When the distance between the steel pipe pile 2 and the friction pile 1 is different, by changing the angle of the connecting rod 11, the fixer 12 can always tightly support the friction pile 1, and play an auxiliary supporting effect on the friction pile 1. The fixing rod 8 A thermal expansion fixing sleeve 9 is sleeved on the surface of the fixing rod 8. The thermal expansion fixing sleeve 9 can be used to limit the fixing rod 8 to prevent the thermal expansion fixing sleeve 9 from falling off due to the vibration generated during the working process of the bridge during the support process, thereby achieving the locking effect of the thermal expansion fixing sleeve 9. A clamping ring 10 is sleeved on the surface of the fixing rod 8. The surface of the clamping ring 10 is fixedly connected to the inner wall of one end of the connecting rod 11, and the other end of the connecting rod 11 is rotatably connected to the inner wall of the fixer 12. The inner wall of the fixer 12 is threadedly connected to the surface of the long screw 13.

[0023] Furthermore, the front side of the fixing device 12 is engaged with the surface of the friction pile 1, and the surface of the long screw 13 is threadedly connected to the inner wall of the screw ring 14. The screw rings 14 are grouped into a group of 3, and there are a total of multiple groups, which are arranged in a linear array on the surface of the long screw 13. The long screw 13 can be limited by the set screw ring 14. When the steel pipe pile 2 is squeezed toward the friction pile 1 due to excessive bridge pressure, the steel pipe pile 2 squeezes the fixing device 12 through the connecting rod 11, and the long screw 13 and the screw ring 14 can limit the fixing device 12, thereby preventing the fixing device 12 from being displaced, thereby protecting the fixing rod 8 from being worn by the clamping ring 10, thereby preventing the fixing rod 8 from limiting the clamping ring 10, and making the fixing effect of the device better.
