Extruding taper sleeve locking-type steel bar joint and method for connecting steel bars by using same

Abstract

The invention discloses an extruding taper sleeve locking-type steel bar joint and a method for connecting steel bars by using the extruding taper sleeve locking-type steel bar joint. The extruding taper sleeve locking-type steel bar joint comprises a double-screw bolt, a pair of jacket nuts, taper sleeves and locking plates, wherein the pair of jacket nuts are arranged on the double-screw bolt back to back, the taper sleeves are sleeved in the jacket nuts, the end surfaces of the taper sleeves are exposed outside the end surfaces of the jacket nuts, and the locking plates are arranged in the taper sleeves. The method comprises the following steps: arranging the pair of jacket nuts, and connecting the jacket nuts with the double-screw bolt in a screwing manner, so that the locking plates are tightly compacted by the taper sleeves in the jacket nuts and are in fastening connection with the steel bars, thus realizing the connection of the steel bars. The method for connecting the steel bars has the advantages that an extrusion device is used for extruding the taper sleeves, so that clearances occur between the jacket nuts and the taper sleeves, then the jacket nuts are connected with the double-screw bolt in a screwing manner so as to eliminate the clearances between the jacket nuts and the taper sleeves, so that the torque is reduced, thus the installation is convenient and labor-saving, the production efficiency is high, and the connection is reliable.

Description

technical field [0001] The invention belongs to the technical field of steel bar locking connection, and in particular relates to an extruded taper sleeve locking joint for connecting steel bars and a method for connecting steel bars using the joint. Background technique [0002] In construction and other production fields, it is often necessary to connect metal wires. For example, in building construction, the problem of connecting steel bars is often encountered. Generally, welding is used to weld and fix the ends of two adjacent steel bars together. 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 the welding interface Not strong enough, easy to rust and open welding. [0003] In recent yea...

Problems solved by technology

[0002] In construction and other production fields, it is often necessary to connect metal wires. For example, in building construction, the problem of connecting steel bars is often encountered. Generally, welding is used to weld and fix the ends of two adjacent steel bars together. Welding equipment is required for welding, and the construction site is often operated at high altitudes. Due to the limited space of the construction site, it is very difficult to use welding equipment, which has huge potential safety hazards. Welding consumes a lot of energy and causes great pollution to the environment; and the welding interface Not strong enough, easy to rust and open welding

[0003] In recent years, a welding-free steel bar connection device has appeared. This device uses threaded connections to thread the ends of two adjacent steel bars, and connects the two ends through long nuts. The threaded connection method is complicated and requires prior or on-site maintenance. There are still potential safety hazards for the use of special equipment for threading the threading of steel bars. In addition, due to the long steel bars, the threading of threading is time-consuming, laborious, low in production efficiency, and high in cost, which limits its popularization and application.
