Description
Technical Field
[0001] This utility model relates to the technical field of building construction, specifically to a movable elevator entrance protection device that can be installed as the building floors are constructed. Background Technology
[0002] During residential construction, the safety railings at the elevator shaft operating platform opening are crucial for ensuring the safety of workers operating within the elevator shaft. Elevator shaft safety railings should generally be at least 1500mm high, with a 200mm high toe board installed at the bottom. The railings are painted red and white as warning colors, and warning signs are hung on the outer side. The safety railings are fixed at the top, and the door opens and closes using a tilting mechanism. Φ16mm steel bars are installed at both ends of the safety railing as a pivot point to allow the door to tilt.
[0003] This type of protection presents some safety hazards during construction. The main issue is that when the upper floor slab is being constructed, the elevator shaft operating platform is already installed and in use. At this time, guardrails need to be installed at the elevator entrance on the lower floor. However, because the floor slab frame has not been dismantled, it is not easy to transport the guardrail materials to the elevator entrance. Furthermore, the elevator entrance is easily blocked by the frame, making it difficult to erect guardrails. This makes it inconvenient or undesirable for workers to carry out the work, ultimately resulting in untimely protection of the opening and posing a safety hazard. Utility Model Content
