A threaded steel connection joint

Abstract

The invention belongs to the technical field of threaded steel connection structure, and specifically relates to a threaded steel connection joint; it includes a fixed joint and a movable joint; the two ends of the fixed joint are connected with movable joints through threads; the end of the movable joint is plugged with a fixed sleeve , and a spiral groove is opened on the inner wall of the fixed sleeve; an elastic spiral skeleton is inserted in the spiral groove, and the elastic spiral skeleton is set as a tapered structure; a rubber tapered sleeve is inserted in the elastic spiral skeleton, and the outer wall of the rubber tapered sleeve A thread groove is provided, and the thread groove corresponds to the collar of the elastic helical skeleton; the end of the rubber tapered sleeve is evenly provided with a plurality of elastic engaging blocks, and the multiple elastic engaging blocks surround the end of the rubber tapered sleeve. It forms a tapered snap ring, and multiple elastic snap blocks are fixed on the inner wall of the movable joint through elastic rubber columns; it prevents the threaded steel from detaching or breaking under external tension or vibration, which in turn affects the threaded steel. connection stability.

Description

technical field [0001] The invention belongs to the technical field of threaded steel connection structures, in particular to a threaded steel connection joint. Background technique [0002] Rebar is a must-use steel for medium-sized and above building components. The geometric shape of the transverse rib of imported rebar is mainly ordinary square thread or ordinary oblique square thread. In construction, rebar is usually used for connection. Currently, the rebar connection method usually adopts Horizontal welding, vertical electroslag welding and other welding processes or mechanical connection of connecting sleeves. [0003] However, in the existing mechanical connection through the connecting sleeve, due to the different environments or laying methods of the rebar when it is used, the connection sleeve is prone to detachment from the rebar when the rebar is mechanically connected. At the same time, due to the poor stability of the connection, when the rebar is stretched...

Problems solved by technology

[0003] However, in the existing mechanical connection through the connecting sleeve, due to the different environments or laying methods of the rebar when it is used, the connection sleeve is prone to detachment from the rebar when the rebar is mechanically connected. At the same time, due to the poor stability of the connection, when the rebar is stretched or vibrated by the outside for a long time, it is easy to cause the connection between the connecting sleeve and the rebar to break.
