Installation tool for taper locking rebar splicing joints

Abstract

The invention discloses a taper sleeve locking-type reinforcing steel bar connector and an installation tool of the taper sleeve locking-type reinforcing steel bar connector. The taper sleeve locking-type reinforcing steel bar connector comprises a pair of taper sleeves and a locking plate group, wherein an inner cavity of each taper sleeve is in a conical shape, the outer surface of the locking plate group is in a shuttle shape, the inner surface of the locking plate group is provided with a tooth socket for locking, and the pair of taper sleeves is symmetrically sleeved on the locking plate group; the installation tool comprises pressure heads, a lead screw, a guide rail, a worm gear and a worm, wherein pressure heads are matched with the guide rail and can move in a reciprocating manner along the guide rail, one ends, adjacent to the guide rail, of the pressure heads are provided with threads, the directions of the threads on the two pressure heads are opposite, the threads are matched with the lead screw to form a feed screw nut pair, two ends of the lead screw are respectively provided with positive and negative trapezoidal threads; one end of the lead screw is fixedly connected with the worm gear, and the worm gear and the worm form a worm-gear pair. The slope self-locking principle is used for realizing the occlusion of the locking plate group to the reinforcing steel bar and the fixing between the taper sleeves and the locking plate group, so that the taper sleeve locking-type reinforcing steel bar connector is simple in structure, convenient to operate, low in workload of the operator, high in working efficiency, firm in connection and free from loosening.

Description

technical field [0001] The invention belongs to the technical field of steel bar connection, and in particular relates to a taper sleeve locking type steel bar connection joint and a tool for installing 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.

[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.
