Technical Field
[0001] The present application relates to the technical field of devices for construction sites, and in particular to a protective device for construction sites. Background Art
[0002] With the economic growth and the development of urbanization, there are more and more high-rise buildings in cities. Safety protection is particularly important in the construction process of high-rise buildings. Existing protective devices for construction sites mainly protect the safety of construction workers by connecting protective nets to scaffolding. However, these protective devices have obvious limitations.
[0003] At present, construction sites connect protective nets to scaffolding. The four corners of the protective nets are generally fixed to four scaffoldings by bundling. When objects fall from high altitude, the objects fall on the protective nets, which intercept the falling objects and prevent them from falling to the ground and causing harm to pedestrians, thereby reducing the threat of falling objects to safety.
[0004] However, the scope of scaffolding construction is limited, and thus the scope of protection of the protective net is limited. Once the falling range of high-altitude falling objects exceeds the construction range of the scaffolding, the existing protective net will be difficult to play an effective protective role, and thus cannot eliminate the safety threat of high-altitude falling objects to pedestrians on the ground. In order to increase the protection area of the protection net and not be completely limited to the erection range of the scaffolding, the present application provides a protection device for a construction site.
[0005] The present application provides a protective device for a construction site using the following technical solution: A protective device for use at a construction site comprises a first protective component, a first connecting component for connecting the first protective component to a scaffold, and a second protective component connected to the first protective component, wherein the first protective component comprises a pair of first support rods and a first protective net arranged between the first support rods, the first connecting components are arranged as a pair, corresponding one-to-one to the first support rods respectively, the first support rods are connected to the first connecting component, and the second protective component is connected to the first support rod to further expand the protective area.
[0006] By adopting the above technical solution, the present application fixes the first protection component on the two outermost scaffolds through the first connecting component, instead of fixing the protection net between the four scaffolds, and effectively extends the first protection net out of the range of the scaffolding construction through the first support rod, thereby increasing the protection area. In addition, the present application also provides a second protection component, which connects the second protection component to the first support rod to further expand the protection area.

[0009] By adopting the above-mentioned technical solution, the present application can flexibly adjust the relative position between the first protection component and the second protection component through a sliding connection, thereby realizing flexible adjustment of the protection area, enabling the device to adapt to the needs of different construction scenarios and improving the protection effect.
[0010] Optionally, it also includes a second connecting component fixedly connected to the first connecting component for connecting the second support rod.

[0012] By adopting the above technical solution, this structure not only increases the bearing capacity of the second support rod, but also effectively prevents the first sliding block from completely detaching from the sliding groove, thereby ensuring the safety and reliability of the device.
[0013] Optionally, a buffer assembly is provided on each of the second support rods.
[0014] Optionally, the second support rod is provided with a mounting groove at one end close to the vertical rod, and the mounting groove is a T-shaped groove.

[0028] When in use, the first support rod 11 is fixed to the two outermost scaffolds respectively through the first connecting assembly 2, and the first protection net 12 is effectively extended out of the range of the scaffolding through the first support rod 11, thereby increasing the protection area, and then the second support rod 31 is controlled to slide outward, so that the second protection net 32 continues to extend outward on the basis of the first protection net 12, further expanding the protection area; Therefore, the present application fixes the first protection component 1 on the two outermost scaffolds through the first connecting component 2, instead of fixing the protection net between the four scaffolds, and through the sliding cooperation of the first support rod 11 and the second support rod 31, the first protection net 12 is effectively extended out of the range of the scaffolding construction, and the second protection net 32 continues to extend outward on the basis of the first protection net 12, further expanding the protection area.

[0030] In the present application, the first support rod 11 and the second support rod 31 are connected by a sliding connection, which facilitates and flexibly adjusts the relative position between the first protective net 12 and the second protective net 32, realizes flexible adjustment of the protection area, enables the protective device to adapt to the needs of different construction scenes, and improves the protection effect.
[0031] like Figure 1 and Figure 2 As shown, the first connecting component 2 includes a fixing ring 21 and a bolt 22 passing through the fixing ring 21 and being able to press against the scaffolding.
