Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of prestressed pipe pile installation and application, in particular to a prestressed pipe pile connection component. Background Art
[0002] Prestressed concrete pipe piles are referred to as prestressed pipe piles. Prestressed pipe piles are a kind of engineering construction material of hollow cylindrical slender concrete prefabricated components, which are mainly used in large-scale construction projects such as railways and bridges.
[0003] During the use of pipe piles, different lengths of pipe piles need to be selected according to different usage requirements. Therefore, multiple pipe piles need to be connected to each other through connecting components to form a longer pile body. The traditional connection method mainly connects multiple pipe piles by welding. However, since welding is prone to cold welding and leaking welding, resulting in poor connection strength and firmness, pipe piles connected by connectors have gradually become the mainstream connection method.
[0004] However, the existing pipe pile connectors are prone to detachment, and the connectors have poor pull-out resistance. After connection, the connection strength between the pipe piles is poor, which will seriously affect the service life of the pipe piles. Utility Model Content
[0005] The purpose of the present application is to provide a prestressed pipe pile connection assembly to solve the problem that the existing pipe pile connectors are prone to detachment, the connectors have poor pull-out resistance, and after connection, the connection strength between the pipe piles is poor, which will seriously affect the service life of the pipe piles.
[0006] In order to solve the above technical problems, the present application provides a prestressed pipe pile connection assembly, comprising:
[0007] A plurality of threaded holes are arranged on the lower end surface of the upper prestressed pipe pile, and a plurality of mounting holes corresponding to the threaded holes are arranged on the upper end surface of the lower prestressed pipe pile. Each of the threaded holes is arranged along the circumferential direction of the lower end surface of the upper prestressed pipe pile. A threaded rod is screwed into each of the threaded holes. An arc plug is fixed to the lower end of the threaded rod. The connection between the arc plug and the threaded rod is arranged in a radial limiting portion. An elastic clamp corresponding to the radial limiting portion is fixed to the inner side of the lower part of the mounting hole.
[0008] On the basis of the above embodiment, as a preferred implementation mode, a plurality of elastic limit heads arranged obliquely upward are fixed on the circumference of the threaded rod, and the elastic limit heads are arranged in an arc shape;
[0009] Correspondingly, an arc-shaped limiting groove corresponding to the elastic limiting head is also arranged on the inner wall of the mounting hole, and the arc-shaped limiting groove is arranged to be inclined upward.
[0010] On the basis of the above embodiment, as a preferred implementation manner, the arc-shaped limiting groove is arranged close to the elastic clamping ring.
[0011] On the basis of the above embodiment, as a preferred implementation mode, a rubber sleeve located above the arc-shaped limiting groove is further fixed in the mounting hole, and the threaded rod is located in the rubber sleeve.
[0012] On the basis of the above embodiment, as a preferred implementation mode, a steel ring is further welded on the outer periphery of the connection between the upper prestressed pipe pile and the lower prestressed pipe pile.
[0013] It should be further explained that the radial limiting portion is arranged in an arc shape;
[0014] Correspondingly, one side of the elastic clamping ring close to the radial limiting portion is provided in the form of an arc-shaped protrusion.
[0015] It should be further explained that the elastic limiting head and the threaded rod are integrally formed.
[0016] Compared with the prior art, the utility model provides a prestressed pipe pile connection assembly, comprising a plurality of threaded holes arranged on the lower end surface of the upper prestressed pipe pile and a plurality of mounting holes corresponding to the threaded holes arranged on the upper end surface of the lower prestressed pipe pile, each threaded hole is arranged along the circumferential direction of the lower end surface of the upper prestressed pipe pile. When in use, the threaded rod is first screwed into the corresponding threaded hole with the help of a tool, the lower end of the threaded rod is fixed with an arc plug, the connection between the arc plug and the threaded rod is arranged in a radial limiting portion, and the lower inner side of the mounting hole is fixed with a corresponding radial limiting portion. The elastic clamping ring, after all the threaded rods are screwed and installed in the threaded holes, the prestressed pipe pile is lowered, and the arc plug is aligned with the corresponding mounting hole and inserted into the mounting hole. During the process of inserting the arc plug into the mounting hole, the elastic clamping ring expands outward until the arc plug completely passes through the limiting space formed by the elastic clamping ring. The elastic clamping ring then retracts inward and is located at the radial limiting portion, limiting the arc plug and clamping it, which can effectively prevent the arc plug from escaping from the mounting hole, thereby improving the pull-out resistance of the connecting component and the connection strength between the pipe piles, and ensuring the service life of the pipe piles.
