[0002] Pipe shaft openings are to meet the requirements of installing ventilation pipes in buildings. Before the construction of the main structure, corresponding horizontal structural openings need to be reserved from bottom to top. Due to the influence of building space, pipe shaft openings are usually set in the corners of the room or at the base of the building wall. These places often have dim light, difficult horizontal protection, falling objects from high altitude, etc., posing a major safety hazard.

[0003] For the protection of horizontal openings in this area, the traditional approach is to embed steel bars laterally and insert steel pipes as the keel, and use wooden formwork as the protective material. Over time, this type of hard closure is often overturned by humans, the wooden materials are aged and damaged, and it is easy for people to step on air or step through the protection. If it is not replaced in time, there will be a major safety hazard, and construction workers will need to repeatedly check, repair, and replace the protective materials. In addition, this approach involves embedding steel bars, fixing keels, laying formwork, etc., which has a complicated process, a short lifespan, and poor turnover efficiency.
