Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, relates to an environmentally friendly construction site enclosure, its installation method, and its construction method. Background Technology

[0002] Construction engineering refers to the construction of building facilities, such as common urban roads, bridges, subways, various pipelines closely related to daily life, as well as the construction of squares and urban green spaces. Construction site fencing, as an important part of construction projects, serves to divide and protect structures. However, existing construction site fencing requires tightening a large number of bolts during installation, making the entire installation process time-consuming and labor-intensive, thus extending construction time. Furthermore, its protective range is not adjustable, making its use complex in practical applications. Therefore, there is an urgent need to design an environmentally friendly construction site fencing system, along with its installation and construction methods, that can not only flexibly adjust the protective range of the fencing but also achieve rapid assembly and disassembly.

[0003] A search revealed numerous patents related to the technical application of construction site fencing structures and their construction methods. For example, Chinese patent application number 202110881196X, entitled "An Adjustable Construction Site Fencing Structure," discloses an adjustable construction site fencing structure comprising a main frame, a toothed plate, guide columns, a support plate, a horizontal perforated plate, and a vertical perforated plate. A handwheel runs through the interior of the main frame, and the output end of the handwheel is located inside the main frame and fitted with a gear for driving the toothed plate to slide horizontally. The bottom end of the toothed plate is fixed. A movable perforated plate is connected so that the movement of the movable perforated plate drives the bottom end of the support plate to slide horizontally along the horizontal perforated plate via the guide column. A lifting plate is screwed to the top of the support plate. This adjustable enclosure structure for building construction, by setting up a support plate, allows the handwheel to rotate within the main frame, driving the gear plate to slide horizontally via the gear. The movement of the gear plate drives the guide column to move via the movable perforated plate. The movement of the guide column drives the bottom end of the support plate to slide along the horizontal perforated plate. At the same time, the movement of the guide column drives the lifting plate to slide vertically along the vertical perforated plate via the support plate, thereby realizing the height adjustment operation of the lifting plate.

[0004] For example, Chinese patent application number 202210063468X, entitled "A Safety Fence Device for Construction Area and its Installation Method," discloses a safety fence device for construction area and its installation method. A first ring is provided on one edge of the main fence panel, and a second ring is provided on the other edge, vertically offset from the first ring. A through groove is provided on the first ring facing the second ring, and a movable groove is provided on the second ring away from the first ring. A columnar part is provided on one side of the secondary fence panel. By offsetting the first and second rings vertically, the first ring on the side of one of the two adjacent main fence panels and the second ring on the side of the other main fence panel can be engaged. The through groove limits the secondary fence panel, preventing it from rotating around the first or second ring. The two adjacent main fence panels can deflect around the columnar part on one side of the secondary fence panel around their engagement point, thus achieving an adjustable angle between the two adjacent main fence panels.

[0005] The above solutions are all good explorations of fence structures and their construction methods, but there is still room for further optimization. The industry has never stopped exploring fence structures and their construction methods. Summary of the Invention
