Description

Technical Field

[0001] This utility model relates to the field of construction site enclosure design, and in particular to a wind venting channel for construction site enclosures in windy areas. Background Technology

[0002] In windy areas, construction site fences often face strong winds. Unlike traditional fences that are continuously enclosed, to prevent the wind from exerting all its force on the fence surface and causing excessive overturning force, gaps are often left at certain intervals to allow wind to escape and reduce the overall overturning force of the fence.

[0003] Currently, the site fencing design does not consider wind unloading in windy conditions, causing wind force to concentrate on the edges of the fencing. This makes the edges of the fencing along the wind unloading channels weak points, especially in windy environments. The direct impact of wind on the edges affects the structural stability and safety, making the fencing susceptible to being blown down, deformed, and generating significant noise. These problems not only threaten construction safety but also hinder the smooth progress of construction. Therefore, a fencing edge reinforcement design is needed to effectively resist the direct impact of wind on the fencing edges, enhancing the stability and safety of the fencing. Summary of the Invention

[0004] This utility model aims to address the shortcomings of existing technologies by providing a wind-dissipating channel for construction site enclosures in windy areas. By optimizing the airflow unloading of the enclosure through a flow guiding device, it reduces the concentrated pressure of wind on the edges of the enclosure, thereby improving the wind resistance and safety of the enclosure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A type of air venting channel for construction site enclosures in windy areas, wherein the construction site enclosure is provided with multiple pre-reserved air venting channels at intervals, and a flow guiding device is inserted into the air venting channel.

[0007] The aforementioned flow guiding device is figure-eight shaped, with its two side edges tilting outwards and forming a certain angle with the plane of the side of the construction enclosure.

[0008] The flow guiding device is made of a thin steel plate bent into an arrow shape on one side. Both ends of the thin steel plate are bent to the inside of the arrow tail end, and an insertion seam is formed at the arrow tail end. The thickness of the thin steel plate is 3mm.

[0009] The edge of the construction enclosure of the air unloading trough is inserted into the joint of the flow guiding device.

[0010] The spacing between the air unloading troughs is between 3m and 5m.

[0011] The beneficial effects of this utility model are: the utility model reserves air vents on the fence, and the air vents are connected to the air guide device. The figure-eight air guide device can reduce wind resistance and increase the efficiency of airflow through the air vents. At the same time, it can also effectively improve the rigidity of the fence edge and prevent the fence from deforming or collapsing due to wind. Attached Figure Description

[0018] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] A type of wind-relief duct for construction site enclosures in windy areas. The construction enclosure 3 is provided with multiple pre-reserved wind-relief ducts 1 at intervals. A flow guiding device 2 is inserted into the wind-relief duct 1. The construction enclosure 3 is made of sheet metal, and its length is determined according to the actual needs of the construction site.

[0021] The airflow guiding device 2 is V-shaped, with its two side edges inclined outwards and forming a certain angle with the plane of the side of the construction enclosure 3. This V-shaped design not only effectively reduces direct contact between the airflow and the enclosure edge but also optimizes airflow guidance, allowing the airflow to flow smoothly into the exhaust duct and be discharged successfully. The outward inclination of the two side edges of the V-shape, forming a certain angle with the plane of the enclosure side, allows the airflow to slide along the curved steel plate surface, reducing turbulence and eddies generated by the airflow and lowering noise and structural vibration caused by wind impact.

[0022] The flow guiding device 2 is constructed by bending a thin steel plate into an arrow shape on one side. Both ends of the thin steel plate are bent to the inner side of the arrow's tail, forming an insertion joint 21 at the tail end. The thickness of the thin steel plate is 3mm. The edge of the construction enclosure 3 of the air duct 1 is inserted into the insertion joint 21 of the flow guiding device 2. The flow guiding device 2 is fixed to the edge of the construction enclosure through an insertion design, eliminating the need for welding. Instead, it relies on the pressure from both ends of the flow guiding device to tightly bond with the enclosure structure, forming a stable fixation effect. It is secured by slight manual or mechanical pressure. This method of installation is quick and convenient, requiring no special tools, reducing construction difficulty and cost. Furthermore, the flow guiding device 2 can be easily disassembled for later maintenance, adjustment, or replacement, reducing maintenance difficulty and allowing for recycling.

[0023] The spacing between the air ducts 1 is between 3m and 5m. The air ducts 1 are reserved at appropriate intervals in the construction enclosure 3 according to the on-site wind force. The spacing between the air ducts 1 can be selected between 3m and 5m depending on the specific situation. The width of the air ducts 1 should be adjusted according to the wind strength and wind direction to ensure that the airflow can flow out smoothly and will not cause wind accumulation.

[0024] The design of the figure-eight-shaped airflow guide device 2 effectively enhances the edge rigidity of the construction enclosure 3. After passing through the airflow guide device 2, the wind force can be evenly distributed, preventing the windflow from being too concentrated on the edge of the construction enclosure 3, thereby reducing the risk of deformation or collapse of the construction enclosure 3 due to excessive wind force. In addition, the figure-eight structure also increases the rigidity of the edge of the construction enclosure 3, enabling the construction enclosure 3 to remain stable even under high wind speeds, making it less likely to be blown down or cause other safety hazards.

[0025] The design of the air duct 1 of this invention has been tested in actual construction wind conditions. The results show that, even with wind speeds as high as 25 m / s, the construction enclosure 3, after the air duct 1 is equipped with the air guiding device 2, can effectively reduce the impact of wind on the construction enclosure 3, ensuring the stability of the construction enclosure 3. Especially under high wind speeds, the construction enclosure 3 did not exhibit significant tilting or collapse, and noise was significantly reduced.
