Plug-in structure and precast pile connecting mechanism

Abstract

The invention provides an inserting structure and a precast pile connecting mechanism. The inserting structure comprises a first sleeve, a second sleeve, an inserting rod, an elastic sleeve, a limiting piece and a tensile piece, and the inserting rod is fixedly installed on the first sleeve; a first latch group arranged in the axial direction is arranged on the outer circumferential wall of the insertion rod, and a second latch group matched with the first latch group is arranged on the inner circumferential wall of the limiting piece; the elastic sleeve is sleeved with the limiting piece, the elastic sleeve and the limiting piece are both contained in the second sleeve, the tensile piece is fixedly connected to the second sleeve, and the elastic sleeve can elastically expand so that the inserting rod can be inserted into the limiting piece. The first latch group and the second latch group are meshed with each other under the elastic contraction of the elastic sleeve; wherein the inserting rod comprises a connecting part and an inserting part which are arranged in the axial direction and fixed to each other, the connecting part is used for being connected with the first sleeve, a first groove extending in the axial direction is formed in the inserting part, the inserting part comprises a plurality of fins, and the fins are arranged in a surrounding mode and enable the inserting rod to contract in the radial direction.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a plug-in structure and a prefabricated pile connection mechanism. Background technique [0002] In the field of construction technology, it is often necessary to butt and fix the ends of two prefabricated prefabricated pile connection mechanisms to extend the length of the prefabricated prefabricated pile connection mechanism to meet specific construction needs. The commonly used docking method is to set up a quick docking assembly between two prefabricated prefabricated pile connection mechanisms. The quick docking assembly is respectively connected with the axial steel bars in the two prefabricated prefabricated pile connection mechanisms, and can be inserted into each other to form a non-removable joint. Fixed connection. [0003] The connection stability of the existing quick docking assembly after docking is low, and it is easy to shake or even suffer strength damage ...

AI Technical Summary

Problems solved by technology

[0003] The connection stability of the existing quick docking components after docking is low. When it is subjected to lateral shear or impact, it is easy to shake or even suffer strength damage. It cannot ensure that the prefabricated prefabricated pile connection mechanisms at both ends remain reliably relatively fixed.
