Embodiment

[0031] Step a. According to the diameter and type of the connecting steel bar, use the supporting stud 1 with connecting cap and the mechanical connecting sleeve 2. Connecting cap 12 of column 1, such as figure 2 shown;

[0032] Step b. Before the prefabricated component or the steel bar skeleton is bound to the steel bars, process the ends of the first connecting steel bar 3 and the second connecting steel bar 4 to be connected and make threaded threads. The depth and length of the threaded heads must meet the corresponding requirements of mechanical connection. Such as image 3 shown;

[0033] Step c, on-site positioning and fixing of prefabricated components or reinforced skeletons, such as Figure 4 As shown, to ensure that the connectors can be screwed in accurately and the gap at the joint must meet the requirements. When the position or alignment of the connected steel bars cannot meet the requirements, the connecting steel bars need to be processed or the connectin...

Abstract

The invention discloses a steel bar mechanical connecting structure and an installation method. The steel bar mechanical connecting structure comprises a stud with a connecting cap, and a mechanical connecting sleeve. The stud with the connecting cap is formed by a stud body and the connecting cap integrally, wherein the connecting cap is of an outer-hexagonal head structure, the connecting cap is internally provided with an internal thread, the stud body is provided with an external thread, and the mechanical connecting sleeve is connected to the stud body in a screwed mode. After to-be-connected steel bars at the two ends are screwed into and connected with the steel bar mechanical connecting structure in place, torque is applied to the stud with the connecting cap, residual deformation of steel bar connection can be reduced, and connection quality is guaranteed. The steel bar mechanical connecting structure can be used for the condition that both the connection steel bars at the two ends cannot rotate, is mainly used for connection of steel bars between prefabricated reinforced concrete members and integral steel bar binding frameworks, and can also be used for connection of ordinary steel bars.

Description

technical field [0001] The invention belongs to the technical field of steel bar mechanical connection, and in particular relates to a steel bar mechanical connection structure and an installation method. Background technique [0002] The mechanical connection of steel bars is a new type of steel bar connection technology, known as the "third-generation steel bar joint" after binding and electric welding. At present, there are three common mechanical connection methods for steel bars: (1) Sleeve extrusion connection joints, through the extrusion force, the connecting steel bars and sleeves are plastically deformed and tightly occluded, but the hydraulic equipment is relatively heavy and inconvenient for on-site construction; (2) The taper thread connection joint is formed by the conical thread bite of the end of the steel bar and the connector end. The taper thread head is prefabricated in the factory, and only a torque wrench is required for on-site construction. It is easy...
