Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, in particular to a hole protection device. Background Art

[0002] In construction projects, openings are reserved for the installation of subsequent engineering equipment or the temporary transportation of materials. There are vertical openings, such as door openings, elevator shaft openings, or edge protection, and there are also plane layouts. Whether it is a plane or vertical opening, temporary measures are required for safety protection before permanent equipment or facilities are installed to ensure the safety of construction space operations.

[0003] The current protective measures usually use customized safety guardrails to block the holes on the facade, use steel plates or templates to cover the holes on the plane, or use fences for isolation. Since the size of each hole is different, the existing protective measures need to be customized, which has poor applicability. In addition, the existing protective measures will drive expansion bolts into the adjacent buildings when fixing, which will damage the surface of the adjacent building structure, affecting the service life and surface quality of the structure.
