Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing jumper steel bars, in particular to a lightning protection grounding jumper wire manufacturing device. Background Art

[0002] In the construction of building projects, the lightning protection grounding grid and the lightning protection down conductor mostly use the threaded steel bars in the civil construction for lightning protection grounding. Among them, the most commonly used are the main bars in the foundation as the grounding grid and the main bars in the column as the down conductor. However, most of the main bars are mostly threaded and tied. According to the requirements of the specifications, jumper wires are required to meet the requirements of the specifications. The traditional jumper wires made by manual bending have various shapes and different lengths, which wastes materials and has a low pass rate. Because lightning protection grounding is a concealed project, once it fails the acceptance, it is difficult to repair and causes secondary damage to the main bars. After the construction is completed, the failure of the grounding resistance test will unnecessarily increase the expenditure of the project cost. Based on this, the utility model proposes a lightning protection grounding jumper wire production device. Utility Model Content
