Technical Field
[0001] This utility model belongs to the technical field of rib bending devices, specifically relating to a portable fixed-distance rib bending device. Background Technology
[0002] In reinforced concrete structures, to enhance resistance to deformation and ensure the overall structural performance, hook bars are installed at joints between main reinforcement layers to guarantee the integrity of the reinforced structure. Traditional construction methods include two approaches: First, hook bars are bent according to design dimensions and then transported to the site for installation. However, due to factors such as the design hook angle, processing, and installation accuracy errors, the hook bars cannot achieve a tight fit with the main reinforcement, failing to meet design quality requirements. Second, only one end of the hook bar is pre-bent, and the other end is bent on-site using a simple lever after installation. Again, due to the lack of a reliable support point, a tight fit between the hook bar and the main reinforcement cannot be effectively guaranteed. Furthermore, the bending process involves a component force on the alignment of the main reinforcement, affecting the interlayer spacing and failing to effectively guarantee the installation quality of the hook bars.
[0003] Existing rebar bending tools have the following drawbacks: they cannot effectively ensure the tightness between the rebar and the main rebar, cannot guarantee the accuracy of the spacing between main rebar layers and the angle of the rebar hook, cannot effectively guarantee the installation quality of the rebar, and have uncontrollable costs and limited application scope.
