Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a construction safety protection grid. Background Art

[0002] Construction safety grids play a vital role on construction sites. They provide safety protection for construction workers and prevent accidents such as accidental falls and object strikes. Such grids are usually used on the periphery of scaffolding to prevent construction workers from falling from heights or objects from falling from the scaffolding. They are usually made of flame-retardant, dust-proof and durable materials such as polyester mesh, galvanized sheet metal, etc. In the existing technology, construction safety protection grids often have problems such as difficulty in storage and inconvenience in transportation. Specifically, traditional grid designs often lack flipping and folding functions, resulting in a large space occupied when not in use, which is not conducive to storage and transportation. In addition, the installation and disassembly process is relatively cumbersome and requires a lot of manpower and time. At the same time, traditional grid structures are often relatively simple and lack the flexibility of modular splicing, making it difficult to meet the diverse needs of construction sites. For this reason, we propose a construction safety protection grid. Utility Model Content
