Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a high-altitude fall prevention device in a limited space. Background Art

[0002] Anti-fall nets are usually made of high-strength, corrosion-resistant and weather-resistant materials, such as polyester fiber, nylon, steel wire rope, etc., to ensure that they can maintain stable performance in various harsh environments. At the same time, the design of anti-fall nets also needs to take into account factors such as their load-bearing capacity, mesh size, and fixing method. The working principle of the anti-fall net is that when a person or object falls from a height, the anti-fall net can quickly unfold and support the falling object, slow down the impact force, and reduce the falling speed of the falling object, thereby reducing injuries.

[0003] In the construction field, anti-fall nets are widely used in high-altitude work sites such as high-rise building construction, bridge construction, and sanitation operations to prevent workers from falling from heights. In industrial production, anti-fall nets are also often used to prevent materials from falling from heights to ensure production safety; in addition, anti-fall nets can also be used in public places such as zoos and amusement parks to prevent animals or tourists from falling from heights.

[0004] When a project is under construction and needs to perform aerial work, in order to prevent construction workers inside the building and objects from falling from heights, causing high-fall accidents, many construction projects will install anti-fall nets outside the building scaffolding. Since the construction area of ​​some projects is small, the width of the construction channel is only enough for construction vehicles to enter and exit, and sufficient construction space is also required for concrete pouring on both sides of the building. Considering that it is necessary to meet construction requirements and take into account safety responsibilities, it is necessary to design a new type of convenient and mobile high-altitude anti-fall device.
