Description

Technical Field

[0001] The utility model relates to the technical field of steel bar sleeves, in particular to a split steel bar sleeve for steel bar connection. Background Art

[0002] The current steel bar connections include welding connection, mechanical connection and binding connection. Among them, mechanical connection is to process the end of the steel bar into a threaded shape, and then install a threaded sleeve and connect the two groups of steel bars together by bolting, so that the steel bar can be extended and lengthened. This connection method is more stable than binding connection and more convenient than welding connection.

[0003] For example, a combined steel bar connecting sleeve with application number CN201821980537.9 includes a connecting sleeve, wherein two groups of steel bars are sleeved on the top and bottom of the connecting sleeve, and the outer side of the steel bar is sleeved with an internal threaded sleeve that matches with the steel bar, and the internal threaded sleeve and the steel bar are threadedly connected, and an annular groove is installed on the top and bottom of the connecting sleeve, and a collar is arranged inside the annular groove. The utility model device can adjust the insertion depth of the steel bar in advance through the mutual cooperation of the two groups of internal threaded sleeves and the connecting sleeve, and the installation and disassembly of the connection are more convenient. The insertion depth of the steel bar can be observed through the observation window and the scale. The mutual cooperation of the collar and the annular groove makes the installation of the connection more compact, and improves the fixing effect of the steel bar. The positioning rod is pushed through the mutual cooperation of the handle, the screw shaft, the screw sleeve, the mounting plate and the support plate.

[0004] This solution has baffles, handles, screw shafts and other items on both sides to assist in pushing the internally inserted steel bars and perform secondary fixation. However, this method will act on the steel bars on both sides at the same time. If the steel bars need to be extracted and inserted individually, it will cause other parts to loosen or clamp together, which is very inconvenient. Utility Model Content
