However, this scheme also has a fly in the ointment: the outer part of the splice is smooth, and it will slip when it is snap-fitted with the snap ring, thereby forming a free stroke and causing a large gap between the two piles

Embodiment 2

[0047] The structure and working principle of this embodiment are basically the same as that of Embodiment 1, the difference is that, as figure 2 As shown, the inner diameter of the channel 12 gradually decreases from the end away from the snap ring positioning cavity 13 to the end having the snap ring positioning cavity 13 . Therefore, the plug joint 102 of the insertion rod 103 can be close to the inner wall of the channel 12, and when the plug joint 102 is inserted to a certain depth, it can play a positioning role.

[0048] An end of the nut body 10 away from the snap ring positioning cavity 13 extends radially of the nut body 10 to form a nut limiting ring 16 . In this embodiment, the nut limiting ring 16 is circular. Of course, the nut limiting ring 16 can also be in other shapes, such as quadrangular, polygonal, elliptical and so on. When the intermediate nut 1 is completely screwed into the second tension nut 22, the nut stop ring 16 compresses the end of the second...

Abstract

The invention belongs to the technical field of building components, and relates to an insertion connecting component with a tension connection function. By the aid of the insertion connecting component, the technical problem of unreliability in connection in the prior art can be solved. The insertion connecting component comprises a first tension nut and a second tension nut. The first tension nut and the second tension nut are respectively fixed to two ends of a prefabricated member, an insertion rod is detachably connected into the first tension nut, a middle nut is detachably connected into the second tension nut, an elastic component is arranged in the second tension nut, a clamp ring is arranged between the middle nut and the elastic component, the insertion rod can be clamped by the clamp ring when being inserted into the middle nut, the middle nut comprises a nut body, external threads are arranged on the outer wall of the nut body, a channel is arranged inside the nut body, an insertion connector can penetrate the channel, an end of the channel is expanded to form a clamp ring positioning cavity capable of accommodating the clamp ring, a clamp ring limiting cavity is arranged at an end of the clamp ring positioning cavity, and the clamp ring can be blocked by the clamp ring limiting cavity when slipping towards the end of the clamp ring positioning cavity and accordingly can be prevented from slipping out of the clamp ring positioning cavity. The insertion connecting component has the advantages that the insertion connecting component is stable and reliable in insertion procedures, and accordingly the construction work efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of building components, and relates to a strong tension connection connector, which is suitable for the connection between prefabricated parts. Background technique [0002] Due to the relatively poor quality stability of immersed tube piles, prefabricated prestressed concrete piles have developed rapidly in recent years. Prestressed concrete square piles are one of the pile types. Existing concrete prestressed square piles generally have a square shape. cross section. In the piling process, piles of different lengths should be selected according to different needs, which requires the piles to be connected to each other to form a longer pile body. [0003] Both ends of the existing prefabricated parts (prefabricated piles) are provided with steel plates, and the square piles are connected by mutual welding between the steel plates. After the connected pile body is pressed into the ground when the pile is p...
