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 threaded connection with the end part of a first steel bar, the second connecting sleeve is in threaded connection with the end part of a second steel bar, and external threads are arranged on at least part of the outer walls of the first connecting sleeve and the second connecting sleeve correspondingly; internal threads are arranged on the inner wall of the outer sleeve, and the outer sleeveis in threaded connection 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 part, close to the second connecting sleeve, of the first connecting sleeve and inserted into a through hole of the second connecting sleeve. The invention further provides a construction method of the steel bar sleeve joint. According to the steel bar sleeve joint, after the steel bars are connected with the sleeve joint, no gap exists, and the fault-tolerant capacity is high.

Description

technical field [0001] The 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 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 not easy to control due to the on-site operation of the extrusion indentation, resulting in hidden dangers in the quality of steel bar connections. Contents of the invention [0003] Based on the analysis of the current status, the prese...
