[0002] The primary function of a protective shed built on a construction site is to prevent falling objects from above and injuring workers below. It also provides protection from rain, snow, and the sun. Currently, protective sheds used on construction sites are constructed by placing two layers of wooden boards on a pre-assembled mounting frame. However, the cushioning effect of these two layers of wood is less than ideal, and falling objects can easily penetrate the protective layer and fall, posing a safety hazard to those who need protection. Furthermore, when encountering rainy or snowy weather, snow easily accumulates on top of the shed and is difficult to clean. When the snow is too thick, it puts a heavy burden on the shed, posing a safety risk of collapse. Therefore, a construction site protective shed is needed to address the above issues.
