High strength steel bar connecting structure capable of achieving rotatable connection, and operating method

Abstract

The invention discloses a high strength steel bar connecting structure capable of achieving rotatable connection, and an operating method. The connecting structure comprises a steel bar A and a steelbar B, and threads are formed in the ends of the steel bar A and the steel bar B through machining; the end of the steel bar A is provided with a connecting piece A in a sleeving mode, and the end ofthe steel bar B is provided with a connecting piece B in the sleeving mode; the connecting piece A is hinged to the connecting piece B, and the exterior of the connecting piece A is provided with a locking cylinder A in the sleeving mode; and the exterior of the connecting piece B is provided with a locking cylinder B in the sleeving mode. The connecting structure has the advantages of rational design, the simple structure, rotatability and higher safety, and is not prone to loose and fall off.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a rotatably connected high-strength steel bar connection structure and an operation method. Background technique [0002] With the transformation and upgrading of the construction industry and the processing and manufacturing industry, as well as the demand for sustainable development of the construction industry, my country has increased the technological development, promotion and application of high-strength steel bars. On January 16, 2012, the coordination group of high-strength steel bars officially released the "Guiding Opinions on Accelerating the Application of High-strength Steel Bars", which is the promotion of the Ministry of Industry and Information Technology and the Ministry of Housing and Urban-Rural Development to promote the coordinated development of upstream and downstream industries and realize the reduction of consumption. Important move for ste...

Problems solved by technology

The existing steel cage connection adopts the straight thread connection technology of long wire head steel bar. The implementation method is to install the steel bar straight thread connection sleeve on the steel bar, screw it into the steel bar to be connected and tighten the joint, but when connecting the steel bar, not only the Reinforcement is connected in a straight line, and vertical connection is also required. Although the connection structure in the prior art can connect the reinforcement, it cannot be rotated; at the same time, the threaded connection in the prior art may be loose, resulting in the connection between the reinforcement. loose, dangerous
