Technical Field
[0001] The utility model relates to the technical field of building engineering construction, in particular to a device for arranging a protective layer pad between a template and a steel bar. Background Art
[0002] The importance of the steel bar protective layer lies in its ability to effectively protect the steel bars from damage by external environmental factors, thereby ensuring the strength and durability of the concrete structure. These external damages may include corrosion, collision, and fatigue, which will greatly reduce the performance of the concrete structure, thereby affecting its service life and safety. However, in on-site construction, it is inevitable that the steel bar protective layer will be inaccurately set due to various reasons such as line positioning and workers' misalignment of binding, resulting in direct contact between the beam and wall steel bars and exposed steel bars after demolding. At this time, it is necessary to add pads between the formwork and the steel bars, but it is difficult to manually set pads between the completed formwork and the steel bars in the prior art, so the present application invents a device for setting protective layer pads between the formwork and the steel bars.
