Non-shearing rapid strong-pulling butt-joint fastener for building pipe pile and connecting piece

Abstract

The invention relates to the field of buildings, in particular to a non-shearing rapid strong-pulling butt-joint fastener for a building pipe pile and a connecting piece. The fastener comprises a first sleeve and a second sleeve, and further comprise a spherical connecting plug, a limiting mechanism, a buffering mechanism and a locking mechanism, the limiting mechanism comprises two limiting guide columns, two inserting rods and four clamping assemblies, the locking mechanism comprises a locking ring, two conical clamping sleeves and two locking assemblies, the buffering mechanism is arranged below the locking mechanism and comprises a circular sleeve shell and an elastic telescopic assembly, the elastic telescopic assembly is arranged at the bottom of the inner side of the second sleeve, and the circular sleeve shell is arranged at the top of the elastic telescopic assembly. According to the non-shearing rapid strong-pulling butt-joint fastener for the building pipe pile and the connecting piece, the stress transmission speed is higher, the existing detection standard can be met, the butt-joint efficiency is higher, and the preparation quality of a butt-joint prefabricated part can be improved.

Description

Technical field [0001] The present invention relates to the field of architectural, and more particularly to a non-shear rapid pull docking fastener and a connecting member. Background technique [0002] In the current detection standard, it is detected that stress delivery, and the laborer in the prior art is pressed into the ground, due to the steel bar (rod) of the pipe pile and the pipe pile and the strong pull fastener There may be a very small amount of contact between the connecting rods. Although this contact is poor, it is within the scope of reliability, the docking quality between the pipe pile and the pipe does not have any effect, but due to the docking pipe pile. It is pressed into the ground, and the standard and detection method of the current test cannot be supported, so it has a very small amount of the result of the current standard detection, but not ideal results.

AI Technical Summary

Problems solved by technology

[0005] 1. The joint is hard-inserted into the tapered sleeve. Not only is the speed slow when docking, but the efficiency of the docking of the two prefabricated parts is reduced, and it will cause greater wear and tear, which is not conducive to secondary utilization.

[0006] 2. There is no design limit mechanism, and the micro-rotation phenomenon is easy to occur after the joint is inserted, which will cause the straightness of the two prefabricated parts after the butt joint is not high, which will affect its preparation quality
