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.
