Description

Technical Field

[0001] The present application relates to the technical field of building construction, and more specifically, to an electric steel bar hook capable of setting the number of turns. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is round, and sometimes square with rounded corners. It includes plain round steel bars, ribbed steel bars, and twisted steel bars. During the construction of steel bar binding in construction projects, whether the steel bar is firmly tied is an important part of the overall force of the steel bar. At present, on construction sites, workers often use steel bar hooks to tie the intersections of steel bars.

[0003] Regarding the above-mentioned related technologies, the applicant believes that the existing steel bar hook tying workers manually perform binding, which is time-consuming and labor-intensive, and the binding is highly arbitrary. During the binding process, it is necessary to ensure that each binding link is correct, and the binding line cannot be too loose or too tight, and should reach an appropriate degree of tightness. However, the current manual binding operation makes it difficult to use the same force to bind the binding wire, and it is not convenient to control the tightness of the binding wire, resulting in the number of turns and tightness of each binding wire being very different, thereby affecting the binding quality. For this reason, we propose an electric steel bar hook with a set number of turns. Utility Model Content
