Description

Technical Field

[0001] The utility model relates to the field of prefabricated pipe pile construction, in particular to a prefabricated pipe pile connecting device. Background Art

[0002] At present, when constructing prefabricated pipe piles, due to the large depth required by the construction design, a single prefabricated pipe pile is difficult to meet the existing construction design requirements, so most of them use the method of connecting piles to connect the two ends of the prefabricated pipe piles to meet the design and construction requirements. The installation of prefabricated pipe piles is carried out by static pressure or hammering, and pipe pile butt welding is required during the construction process.

[0003] The traditional welding method is to weld short steel bars on the end plate and manually push and support the pipe piles for welding. The welding quality is difficult to control, and it is easy to cause misalignment between the upper and lower pipe piles. In addition, manual pushing and supporting for pipe pile welding is very time-consuming and labor-intensive, and cannot effectively ensure the accuracy of the pipe pile head welding and the stability of the construction quality.

[0004] Therefore, a prefabricated pipe pile connecting device is proposed to solve the above technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is that the traditional welding process of prefabricated pipe piles is usually manual pushing and supporting, the welding quality is difficult to control, and the docking misalignment is prone to occur, which leads to the accuracy of the docking of the pipe pile heads and the stability of the construction quality being affected.

[0006] In order to solve the above technical problems, the technical solutions adopted by the present utility model are as follows:

[0007] A prefabricated pipe pile connection device, comprising a butt collar, the butt collar comprising a left half-ring and a right half-ring sleeved on the head of the prefabricated pipe pile, the connection surfaces of the left half-ring and the right half-ring being provided with a connection wing plate extending radially outwardly along the prefabricated pipe pile, the connection wing plate being provided with a tension bolt hole, and the tension bolt hole being provided with a tension bolt; and also comprising an elastic cushion layer arranged on the butt collar;

[0008] It also includes a plurality of telescopic support rods detachably arranged at the bottom of the docking collar, the telescopic support rods including a sleeve rod and an insertion rod, the insertion rod is locked by a fixing bolt penetrating the sleeve rod wall; the top of the telescopic support rod is also provided with an L-shaped pad, the pad is arranged at the bottom of the docking collar by a transverse mounting bolt;

[0009] A plurality of horizontal through grooves are also provided in the middle of the butt-jointing collar, and the height of the horizontal through grooves is the same as the connecting height of the upper and lower prefabricated pipe piles.

[0010] Particularly, a horizontal support plate is also provided at the bottom of the telescopic support rod.

[0011] Particularly, at least two tension bolts are arranged on the connecting wing plate, and adjacent tension bolts are arranged in opposite directions.

[0012] Particularly, the top of the docking ring is further provided with two semi-funnel-shaped docking rings which are respectively arranged on the left half ring and the right half ring.

[0013] Furthermore, a rigid cushion layer is fixed to the inner wall of the docking ring.

[0014] Compared with the prior art, the utility model has the following advantages and beneficial effects: the utility model has a simple structure and is quick to install. At the same time, it can effectively ensure that the upper and lower prefabricated pipe piles are quickly aligned, and it is convenient to carry out welding construction, avoiding the misalignment of the weld caused by the misalignment of the pipe piles, which affects the hammer resistance, tension resistance and bending resistance of the prefabricated pipe piles; at the same time, the telescopic support rod at the bottom can effectively support the left half ring and the right half ring that have not been fixed and locked, so as to facilitate the adjustment of the height of the docking ring and the alignment of the weld height.

[0020] A plurality of horizontal through grooves 8 are also provided in the middle of the butt-jointing collar, and the height of the horizontal through grooves 8 is the same as the connecting height of the upper and lower prefabricated pipe piles.

[0021] In the present invention, the main working principle is as follows: first, the telescopic support rod 6 is installed at the bottom of the docking collar through the pad 7 and the mounting bolts 71, and then the left half ring 1 and the right half ring 2 of the present invention device are sleeved on the pile head of the bottom prefabricated pipe pile, and pre-connected through the tension bolts 4. Then, by adjusting the height of the bottom telescopic support rod 6, the telescopic support rod 6 can support the pre-connected docking collar, and just expose the welding seam of the upper and lower pipe piles from the horizontal through groove 8. Then, the prefabricated pipe pile to be connected is lifted, and the pre-docking collar at the bottom of the pipe pile is aligned from the top of the docking collar and then slowly lowered. Finally, the left half ring 1 and the right half ring 2 are locked by the tension bolts 4 to ensure that the sleeve is firmly tied and the elastic cushion layer 5 is used to prevent the pipe pile from being damaged by excessive force. The docking collar can ensure that the upper and lower prefabricated pipe piles are quickly aligned to avoid the misalignment of the prefabricated pipe piles.

[0022] As a preferred embodiment, a horizontal support plate 9 is further provided at the bottom of the telescopic support rod 6 .
