Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] The invention provides a connecting sleeve for a finish-rolled threaded steel bar, which is used for connecting steel bars at a construction site. The connecting sleeve of the present invention is based on the steel bars formed in the finish-rolled thread shape during the steel rolling process, and is connected with the external threads of the finish-rolled threaded steel bars, so that the strength and deformation of the connected steel bars are equal to the original steel bars. The connection sleeve of the finish-rolled threaded steel bar of the present invention will be described below in conjunction with the accompanying drawings.
[0021] refer to figure 1 , shows a structural schematic diagram of the connection sleeve of the finished rolled threaded steel bar and the finished rolled threaded steel bar according to the present inven...

The invention relates to a connecting sleeve of finished deformed bars.A connecting thread and a self-locking structure are arranged on the inner wall of the sleeve.The connecting thread corresponds to external threads of the finished deformed bars.The connecting sleeve is screwed to the finished deformed bars through connecting threads and combined with the self-locking structure to be connected with the finished deformed bars in a fastened mode.The self-locking structure is arranged inside the connecting sleeve, and the threads on the peripheral walls of the finished deformed bars are utilized, so that the connecting sleeve and the finished deformed bars are connected in a screwed mode, the thread lathing technology of the steel bars is omitted, workloads are reduced, and the processing time is shortened.The self-locking structure is connected with the threads in the matched mode to be connected with the finished deformed bars in the fastened mode, the steel bars are prevented from being loosened, and connecting strength of the steel bars is ensured.By means of the connecting sleeve, the construction efficiency of the steel bars can be improved, the construction time of the steel bars can be shortened, and good construction benefits are achieved.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a connecting sleeve for a finish-rolled threaded steel bar. Background technique [0002] The commonly used steel bar connection method on the construction site is to thread the head of the steel bar to form an external thread, and then match the adapter sleeve for screw connection. Such connection fits tightly and firmly, and the strength after the steel bar is connected is high, but each steel bar that needs to be connected is all processed by car wire, and there is a large workload and a long defect in processing time. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a connection sleeve for finish-rolled threaded steel bars, which solves the problem of large workload and long processing time due to the need for threading processing on the head of the steel bar in the prior art. The problem. ...
