Problems solved by technology

[0002] At present, in the field of prefabricated construction engineering, there is no mature and popularized prefabricated steel bar connection technology for the longitudinal bar connection of prefabricated concrete components and formed steel bar skeletons. The traditional straight threaded sleeve joints of steel bars need to rotate the steel bar to be able to connect Steel bar connection is not suitable for the longitudinal bar connection of prefabricated components and formed steel bar skeletons. The width and depth of cold extrusion sleeve joints are difficult to control due to the on-site extrusion indentation, resulting in hidden dangers in the quality of steel bar connections

Abstract

The invention provides a steel bar sleeve joint. The steel bar sleeve joint comprises an outer sleeve, a first connecting sleeve and a second connecting sleeve, wherein the first connecting sleeve isin screw joint with the end of a first steel bar, and the second connecting sleeve is in screw joint with the end of a second steel bar; external threads are arranged on at least parts of the outer walls of the first connecting sleeve and the second connecting sleeve; internal threads are arranged on the inner wall of the outer sleeve, and the outer sleeve is in screw joint with the external threads of the first connecting sleeve and the second connecting sleeve, so that the first connecting sleeve and the second connecting sleeve are fixedly connected; and a guide head is arranged at the end,close to the second connecting sleeve, of the first connecting sleeve and inserted into a through hole of the second connecting sleeve. A construction method of the steel bar sleeve joint is furtherprovided. According to the steel bar sleeve joint, after the steel bar is connected with the sleeve joint, no gap exists, and the fault-tolerant capacity is high.

Description

Technical field [0001] The present disclosure relates to the field of prefabricated buildings, in particular to a steel bar sleeve joint and a construction method thereof. Background technique [0002] At present, in the field of prefabricated concrete components, the longitudinal reinforcement of the longitudinal reinforcement and the longitudinal reinforcement of the formed reinforcement skeleton have not yet been mature and popularized assembled reinforcement connection technology. The traditional steel straight threaded sleeve joints can only be combined due to the need to rotate the reinforcement. The steel bar connection is not suitable for the connection of the longitudinal bars of the prefabricated member and the formed steel frame. The width and depth of the cold extrusion sleeve joints are not easy to control due to the on-site operation of the extrusion indentation, resulting in hidden dangers in the quality of the steel connection. Summary of the invention [0003] Bas...
