Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, and specifically relates to the construction of prestressed pipe piles, and more specifically to a prestressed concrete pipe pile splicing structure. Background Technology
[0002] Prestressed concrete pipe piles are widely used in housing construction in many provinces and cities across China due to their advantages such as high cost-effectiveness, high bearing capacity, good pile quality, fast construction speed, no vibration, no noise, and convenient supervision and testing. As a core component of the building foundation industry, the precast concrete pile industry is developing vigorously and in an orderly manner. In recent years, under the guidance of leading enterprises, it has developed in a standardized manner and achieved remarkable results in product innovation and construction method innovation.
[0003] Currently, there are two main splicing methods for prestressed concrete pipe piles: welding and mechanical connection. Welding is labor-intensive, and the welding quality is difficult to guarantee. Mechanical connection is susceptible to failure due to the long-term effects of corrosive environments, and prestressed concrete pipe piles are prone to separation of the upper and lower pile sections during pull-out, causing engineering and safety hazards.
[0004] Therefore, in order to improve the splicing quality and efficiency of prestressed concrete pipe piles and further promote their application, we urgently need to innovate the splicing methods of prestressed concrete pipe piles. Summary of the Invention
[0005] The purpose of this utility model is to solve the problems existing in the prior art and to provide a newly designed prestressed concrete pipe pile splicing structure.
[0006] This utility model is achieved through the following technical solution:
[0007] A prestressed concrete pipe pile splicing structure includes a first prestressed pipe pile and a second prestressed pipe pile. One end of the first prestressed pipe pile is socketed to one end of the second prestressed pipe pile. A socket protrusion is provided at the center of the connection end of the first prestressed pipe pile, and a socket groove is provided at the center of the connection end of the second prestressed pipe pile. A first sleeve is embedded at the center of the end face of the socket protrusion, and an insert rod extending out of the socket protrusion is fixedly connected inside the first sleeve. A locking head is provided at the end of the insert rod. A second sleeve is embedded at the center of the bottom of the socket groove, and multiple elastic locking pieces built into the socket groove are fixedly connected inside the second sleeve. An elastic locking mouth is formed between the inner ends of the multiple elastic locking pieces.
[0008] The socket protrusion on the first prestressed pipe pile is inserted into the socket groove of the second prestressed pipe pile. The insertion rod on the socket protrusion is inserted into multiple elastic locking pieces on the socket groove. The locking head on the insertion rod passes through the elastic locking opening formed by multiple elastic locking pieces and is locked and fixed by the elastic locking opening.
[0009] Furthermore, both the inner wall of the first sleeve and the wall of the insert rod are provided with connecting threads, and the insert rod and the first sleeve are connected by thread engagement.
[0010] Furthermore, the outer end of the elastic locking piece is welded and fixed to the inner wall of the second sleeve, and 2-4 elastic locking pieces are provided and evenly distributed inside the second sleeve.
[0011] Furthermore, multiple recessed grooves are evenly distributed on the side wall of the socket protrusion, and a locking tongue is slidably installed in the recessed groove. The locking tongue and the recessed groove are connected by a spring, which is located in the recessed groove. One end of the spring is fixedly connected to the inner end of the locking tongue, and the other end of the spring is fixedly connected to the bottom of the recessed groove. Multiple locking slots are evenly distributed on the groove wall of the socket recess. The number of locking slots is the same as the number of locking tongues, and the position of the locking slots corresponds to the position of the locking tongues. The locking tongues are inserted into the corresponding locking slots.
[0012] Furthermore, a limiting guide rod is provided in the relief groove. The inner end of the limiting guide rod is fixedly connected to the bottom of the relief groove, and the outer end of the limiting guide rod does not exceed the opening of the relief groove. A through hole is provided on the latch, which passes through its inner and outer ends. The latch is slidably connected to the limiting guide rod through the through hole, and a spring is fitted on the limiting guide rod.
[0013] Furthermore, the latch adopts an inverted trapezoidal block structure.
[0014] This utility model features a scientifically designed and rationally structured pile splicing structure that is easy to operate and provides a strong connection. The application of this pile splicing structure effectively improves the progress of engineering construction, shortens the construction period, ensures the construction quality on the construction site, reduces construction costs, and achieves significant social and economic benefits.
