Description

Technical Field

[0001] This utility model relates to the field of dust control technology in building construction, specifically a dust control device for building construction. Background Technology

[0002] With the rapid development of the social economy, the scale of construction projects is becoming increasingly larger, resulting in significant dust pollution during construction. Activities such as building construction, road and pipeline construction, building demolition, and ground trenching generate large amounts of dust particles, polluting the atmosphere and the surrounding environment. This is particularly problematic in densely populated residential areas. Therefore, dust control devices are needed to isolate the dust generated during demolition and prevent it from affecting the lives of nearby residents. However, current methods of using barriers to isolate the area around demolition sites require adjusting the height of the barriers based on the amount of dust generated during demolition. This lack of adjustment leads to high dust control costs, inconvenience in dismantling and reassembling, and poor dust control effectiveness.

[0003] As disclosed in the prior art, Chinese utility model publication CN215107968U discloses a dust control device for building demolition construction, including an isolation belt. Eight support pipes are evenly installed on the inner side of the isolation belt. One support pipe has fixed blocks fixedly installed on the outer sides of both ends, and guide columns are fixedly installed on the outer sides of the fixed blocks. Guide blocks are installed on the outer sides of both ends of the other six support pipes. Support springs are provided on the upper surfaces of the guide blocks, and buffer plates are installed on the upper ends of the support springs. A first connecting column and a second connecting column are respectively installed on the inner sides of both ends of the remaining support pipe. A conveyor belt is fixedly installed at one end of the first connecting column, and connecting shafts are installed on the inner sides of both ends of the conveyor belt. This utility model, by adjusting the height of the dust-blocking structure, can block different amounts of dust for dust removal operations.

[0004] Through the dust control devices used in the above-mentioned building demolition construction, it is known that the existing technology has the following problems: when separating the area around the demolition construction site for dust control, it is inconvenient to adjust the height of the construction fence according to the amount of dust during the demolition, and it is also inconvenient to disassemble and assemble, and the dust removal effect is not good. Therefore, we need to propose a dust control device for building construction. Utility Model Content
