Description
Technical Field
[0001] The utility model relates to the technical field of building construction guardrails, in particular to a protective railing structure. Background Art
[0002] There are many edge openings involved in housing construction projects, such as the edges that endanger personal safety, such as the perimeter of floors without enclosures or the height of enclosures less than 0.8 meters, the sides of stairs, the edges of platforms or balconies, the perimeter of roofs, and ditches, pits, grooves, deep foundations, etc., which are all safety risk points at the construction site. In order to effectively protect the above-mentioned risk points, edge guardrails are usually used for protection during the construction process.
[0003] Traditional edge protection railings are composed of steel pipes and poles. Since the protection dimensions of the edge openings on site vary, steel pipes often need to be cut during construction, resulting in high labor consumption and material loss. At the same time, steel pipes and poles take up a lot of space, making them difficult to transport and store. In addition, during transportation, steel pipes or poles are prone to collision, causing deformation, which further increases the material loss rate. Utility Model Content
