Taper-sleeve locking-type steel bar connection joint

Abstract

The invention discloses a taper-sleeve locking-type steel bar connection joint. The connection joint comprises an outer sleeve cylinder and inner core connection parts. The inner core connection parts are arranged in the outer sleeve cylinder. The inner core connection parts form a pair. The inner core connection parts comprise supporting seats and a plurality of locking part. The supporting seats of the pair of the inner core connection parts are arranged back-to-back. The outer sleeve cylinder is an inner-cone outer sleeve cylinder. The inner-cone outer sleeve cylinder comprises an inner-cone column cylinder and inner-cone nuts symmetrically arranged on two ends of the inner-cone column cylinder. The inner-cone nuts are threadedly connected with the inner-cone column cylinder. According to the invention, a locking structure in which the outer sleeve cylinder cooperates with the inner core connection parts is adopted. The connection joint is convenient to use. With the connection joint, unidirectional clamping or different-diameter connection can be realized with no assistance of any device, no welding, and no thread sleeve. Connection can be realized with manual screwing. The connection is firm, and has no loosening. As a result of a tensile strength experiment, a tensile strength after fastening connection is greatly higher than that of a welded structure.

Description

technical field [0001] The invention belongs to a locking device for steel bars, in particular to a taper sleeve locking type steel bar connection joint. Background technique [0002] In construction and other production fields, it is often encountered that metal wires need to be connected. For example, in building construction, the problem of mutual connection between steel bars is often encountered. Generally, welding is used to weld the ends of two adjacent steel bars. At the same time, welding equipment is required for welding, and the construction site is often operated at high altitude. Due to the space limitation of the construction site, it is very difficult to use welding equipment, and there is a huge potential safety hazard. Welding consumes a lot of energy and causes great pollution to the environment; and welding The interface is not strong enough, easy to rust and open welding. [0003] In recent years, a welding-free steel bar connection device has appeared. ...
