Description
Technical Field
The utility model belongs to the technical field of the construction, concretely relates to steel bar taper sleeve connecting piece.
Background
The steel bar connection refers to a connection mode of steel bars, and the connection mode of the steel bars mainly comprises binding and overlapping, mechanical connection and welding.
The lashing lap joint is a way of transferring the reinforcement stress through the binding force between the reinforcement and the concrete. Two opposite stressed steel bars are respectively anchored in the concrete of the lap joint section to transmit force to the concrete, so that the stress transmission between the steel bars is realized. The lashed connections waste reinforcing bars due to the long lap length required, and the connections are unreliable.
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 method has the advantages of no open fire operation, simple equipment, energy conservation, no influence of weather conditions, all-weather construction, reliable connection, easy mastering of technology and wide application range.
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 steel bars through the molten metal. Due to the high temperature action, a heat affected zone is formed near the welding seam, the mechanical property of the steel is changed, and the material becomes brittle; the welded structure has continuity, and local cracks can easily extend to the whole body once being generated.
