Description

Technical Field

[0001] The utility model relates to the technical field of edge protection columns, in particular to an edge protection column for high-altitude operations. Background Art

[0002] With the increasing attention paid by the society to the safety rights and interests of workers, the design and application of edge protection columns as one of the important safety protection measures have been widely recognized and developed. New high-strength and lightweight materials are widely used in the manufacture of edge protection columns. These materials not only have higher strength and durability, but also reduce the weight of the columns. The modular design of edge protection columns makes their installation and disassembly more convenient and quick. This design method can adapt to various complex high-altitude working environments and can be quickly adjusted according to actual needs, which improves the flexibility and adaptability of protective facilities.

[0003] However, the existing edge protection columns still have the following defects when in use: they are only fixed with expansion bolts, which destroy the concrete surface and seriously damage the overall structure, and the anti-toppling strength cannot be fully guaranteed. The erection is time-consuming and labor-intensive, most of the structures are unstable, the appearance is relatively unsightly, and it is difficult to meet the standardized construction requirements. The mesh is directly tied to the embedded parts or embedded steel bars, which is perfunctory. The edge protection is extremely unstable, and the mesh itself is also at risk of falling, and cannot meet the safety protection requirements. The assembled edge protection columns increase oblique supports, and the stability is slightly improved, but they are still fixed on the embedded parts or embedded steel bars, with poor stability, and cannot fully exert the safety protection function.
