Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to the field of construction elevator entrance protection technology, specifically referring to a construction elevator entrance protection device for building construction. Background Technology
[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called the "construction site" or "building site."
[0003] Currently, the gap between the elevator entrance and the building structure of conventional construction sites is typically 300mm wide, and these elevators are mostly open without any rigid safety protection devices. The elevator's own steps only descend to the structural beam surface when the elevator doors are open, allowing personnel and vehicles to pass. Since building materials are often heavy, the lack of support in the middle of the steps makes them prone to collapse and deformation when entering and exiting the elevator, creating serious safety hazards. Furthermore, the elevator safety doors on floors are positioned close to the edge of the floor structure; if the doors accidentally open, there is no safe margin for personnel to exit, greatly increasing the risk of personal injury.
[0004] Therefore, it is desirable to provide a construction safety belt suspension device that can protect the gap between the construction elevator entrance and the building structure, thereby reducing safety hazards and preventing personal injury. Utility Model Content
