Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to a retractable steel springboard. Background Art

[0002] At present, most steel springboards use fixed-length steel springboards. However, fixed-length steel springboards are often temporarily fixed by wires when in use, and the steel springboard extension is usually overlapped. However, when this method is used, due to the requirements of the grid size of the steel grid, it is necessary to adapt the site of the steel springboard according to the grid size of the steel grid. The fixed-length steel springboard cannot be used for the construction of all steel grid structures, thereby reducing the turnover of the steel springboard. Moreover, the steel springboard requires additional fixing measures, the fixing process is relatively cumbersome, and the construction time is long. The extension of the fixed-length steel springboard often solves the problem of the extension of the steel springboard by overlapping. The overlap length and the overlap fixing method affect the safe passage of the steel springboard. At the same time, the overlap forms a height difference, which also brings instability to the passage of personnel. These are all undesirable to those skilled in the art. Utility Model Content
