Technical Field
The invention relates to the technical field of auxiliary tools for connecting reinforcing steel bars, in particular to a ferrule type connector for hot-rolled threaded reinforcing steel bars.
Background
At present, the steel bar connection mode mainly comprises three types of binding lap joint, mechanical connection and welding: 1. binding and lapping are the most applied connection mode in the prior reinforcing bar engineering. However, when the steel bars are thick, the binding and overlapping construction is difficult and wide cracks are easy to generate; 2. the welding connection is that the force is directly transferred between the stressed steel bars through molten metal. The force is directly transferred between the stressed steel bars through molten metal. If the welding quality is reliable, the defects in the aspects of strength, rigidity, recovery performance, destructive performance and the like do not exist, and the method is an ideal connection mode. The disadvantage is that it is difficult to ensure stable welding quality in field welding operation. In addition, the welding heat can affect the material of the steel bar and change the mechanical property of the steel bar; 3. the mechanical connection is a steel bar connection mode developed in recent years, the force transmission of the steel bars is realized through a sleeve connected between two steel bars, and the mechanical connection is a form of indirect force transmission. The force transmission between the steel bar and the sleeve can be realized through the occlusion of extrusion deformation, the wedging between threads, the gluing of pouring high-strength cementing materials and the like. The main ways of mechanical connection are: radial and axial extrusion connections, tapered threaded connections, upset straight threaded connections, rolled straight threaded connections, and the like.
