[0002] When constructing a building, it is necessary to use edge protection scaffolding to provide construction workers with a fulcrum and safety protection for high-altitude operations.

[0003] Traditional edge protection external frames usually choose floor-standing or cantilevered frames as structural edge protection (operation) frames. Floor-standing frames are suitable for situations where there is no road next to the building structure. For buildings with roads next to the building structure, cantilevered frames can be used. The supporting structure of the cantilevered frame is a cantilevered beam or cantilevered truss made of steel, which is suitable for reinforced concrete structures, high-rise steel structures or super high-rise buildings.

[0004] However, the cantilever frame is not suitable for single-story structures or buildings with fewer floors due to the high cost. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem of high cost of using a cantilever frame when there is a road next to a low-rise building in the prior art, thereby providing an edge protection frame and a scaffold having the same.

[0006] In order to solve the above technical problems, the utility model provides an edge protection frame, comprising:
