Description
Technical Field
[0001] This application relates to the technical field of high-altitude construction, and particularly relates to a high-altitude anti-falling object device. Background Art
[0002] During the construction process, there are many places where high-altitude anti-falling measures are required, such as atriums, air ducts, etc. Therefore, high-altitude anti-falling devices are generally installed in these places to prevent heavy objects from falling to the ground and prevent safety accidents.
[0003] Currently, as disclosed in the utility model with the authorization announcement number CN218643940U, most high-altitude anti-falling devices are realized by setting anti-falling mesh sheets to prevent heavy objects from falling.
[0004] However, the sizes of heavy objects vary. Some heavy objects smaller than the mesh holes of the anti-falling mesh sheet may fall through the mesh holes. Moreover, all the heavy objects blocked by the anti-falling mesh sheet are pressed on this one anti-falling mesh sheet, which is very easy to damage the anti-falling mesh sheet and cause the anti-falling function to be impaired. Based on this, this application proposes a high-altitude anti-falling object device. Utility Model Content
[0005] This application provides a high-altitude anti-falling object device. By setting three anti-falling meshes with different anti-falling sizes, three size blocking ranges are formed to improve the anti-falling range. At the same time, the three anti-falling meshes form three bearing spaces, and the heavy objects are distributed on the three anti-falling meshes for bearing, avoiding concentration on one anti-falling mesh, not easily damaging the anti-falling mesh, ensuring the normal anti-falling function, and extending the service life of the anti-falling mesh.

The upper anti-falling mesh is fixed to the upper frame opening of the upper support frame, the middle anti-falling mesh is fixed between the two support frames, and the lower anti-falling mesh is fixed to the lower frame opening of the lower support frame.
[0008] The high-altitude anti-falling object device is provided with three anti-falling meshes from top to bottom, and the mesh sizes of the three anti-falling meshes decrease in sequence.

[0031] An embodiment of the present application provides a high-altitude falling object prevention device, which is arranged in a hole 010 of a high-altitude building and can prevent falling objects from the hole 010 and avoid heavy objects from falling from the hole 010.
[0032] As Figure 1 、 Figure 2 and Figure 3 shown, the high-altitude falling object prevention device includes a support ring plate 100, two support frames 200, and three anti-falling nets 300. Among them, the support ring plate 100 is a structure for supporting other components, the support frame 200 is a component for supporting the anti-falling net 300, and the anti-falling net 300 is used to prevent heavy objects from falling to achieve falling object prevention.
[0033] As Figure 2 and Figure 4 shown, the four peripheral edges of the support ring plate 100 are embedded in the peripheral side walls of the hole 010. That is to say, a part of the support ring plate 100 is embedded in the peripheral side walls of the hole 010, and the rest is located inside the hole 010, realizing the fixation of the support ring plate 100 and providing support conditions for other components. During implementation, the support ring plate 100 can be embedded during the construction of the hole 010 to facilitate the installation of the support ring plate 100.
[0034] As Figure 2 and Figure 3As shown, two support frames 200 are stacked, and the two support frames 200 are placed on the support ring plate 100. That is to say, the lower support frame 200 is placed on the support ring plate 100, and the upper support frame 200 is placed on the lower support frame 200. The external dimensions of the support frame 200 match the dimensions of the hole 010. Here, it means that the external dimensions of the support frame 200 are slightly smaller than the dimensions of the hole 010, which is convenient for placing the support frame 200 into the hole 010.
[0035] As Figure 2 and Figure 3 shown, each anti-falling net 300 is provided with many mesh holes (not shown in the figure). Three anti-falling nets 300 are arranged in sequence from top to bottom, and the mesh hole sizes of the three anti-falling nets 300 decrease in sequence from top to bottom, so that the sizes of the heavy objects that the three anti-falling nets 300 can block also decrease in sequence.
[0036] As Figure 3 shown, the upper anti-falling net 300 is fixed to the upper frame opening of the upper support frame 200, the middle anti-falling net 300 is fixed between the two support frames 200, and the lower anti-falling net 300 is fixed to the lower frame opening of the lower support frame 200. In this way, heavy objects with sizes larger than the mesh hole size of the lower anti-falling net 300 and smaller than the mesh hole size of the middle anti-falling net 300 will fall onto the lower anti-falling net 300, heavy objects with sizes larger than the mesh hole size of the middle anti-falling net 300 and smaller than the mesh hole size of the upper anti-falling net 300 will fall onto the middle anti-falling net 300, and heavy objects with sizes larger than the mesh hole size of the upper anti-falling net 300 will fall onto the upper anti-falling net 300, thus forming three anti-falling ranges, and also making the heavy objects distributed on the three anti-falling nets 300.
[0037] The high-altitude anti-falling object device is provided with three anti-falling nets 300 from top to bottom, and the mesh hole sizes of the three anti-falling nets 300 decrease in sequence. During use, the three anti-falling nets 300 can respectively block heavy objects of corresponding sizes, forming three size blocking ranges, improving the anti-falling range. Moreover, the three anti-falling nets 300 form three bearing spaces, and the heavy objects are distributed on the three anti-falling nets 300 for bearing, and it is not easy to damage the anti-falling nets 300.
[0038] Compared with the prior art, the high-altitude anti-falling object device forms three size blocking ranges by setting three anti-falling nets 300 with different anti-falling sizes, improving the anti-falling range. At the same time, the three anti-falling nets 300 form three bearing spaces, and the heavy objects are distributed on the three anti-falling nets 300 for bearing, avoiding concentration on one anti-falling net 300, not easy to damage the anti-falling nets 300, ensuring the normal anti-falling function, and extending the service life of the anti-falling nets 300.
[0039] In some embodiments, as Figure 3As shown in the figure, the high-altitude falling object prevention device further includes two pressing rings 400. One pressing ring 400 is attached to the upper anti-falling net 300 and fixedly connected to the upper support frame 200, and the other pressing ring 400 is attached to the lower anti-falling net 300 and fixedly connected to the lower support frame 200, so that both the upper anti-falling net 300 and the lower anti-falling net 300 are arranged between the pressing ring 400 and the support frame 200 and are fixedly connected, improving the firmness of the upper anti-falling net 300 and the lower anti-falling net 300.
[0040] In some embodiments, as Figure 5 and Figure 6 shown, the frame opening of the support frame 200 is provided with a first ear plate 210, the first ear plate 210 is provided with a first through hole 220, the pressing ring 400 is provided with a second ear plate 410, the second ear plate 410 is provided with a second through hole 420, and the support frame 200 and the pressing ring 400 are bolt-connected through the first through hole 220 and the second through hole 420. The first ear plate 210 and the second ear plate 410 are arranged oppositely, and the first through hole 220 and the second through hole 420 are opposite, so as to facilitate the connection of the first ear plate 210 and the second ear plate 410 through bolts, that is, to realize the connection of the support frame 200 and the pressing ring 400.
[0041] Similarly, in some embodiments, the two support frames 200 are bolt-connected through two first through holes 220, and the contact part in the middle of the two support frames 200 can also adopt the bolt connection method.
[0042] In some embodiments, as Figure 5 shown, first ear plates 210 are provided on all four edges of the frame opening of the support frame 200, so that the first ear plates 210 are evenly distributed, the force is evenly distributed during connection, and the connection is more firm. Correspondingly, the second ear plates 410 on the pressing ring 400 are also arranged in this way. During implementation, two first ear plates 210 can be provided on each edge of the frame opening of the support frame 200 to ensure the structural strength of the connection.
[0043] In some embodiments, as Figure 5 shown, operation holes 230 are provided on all four side walls of the support frame 200, and the operation holes 230 correspond to the first ear plates 210. When connecting by bolts, tools such as wrenches and pliers can extend to the first ear plates 210 through the operation holes 230, facilitating operation.
[0044] In some embodiments, the length of the support ring plate 100 extending out of the hole 010 is at least 200 mm. That is to say, the length that the support ring plate 100 can support is 200 mm, ensuring the support ability of the support ring plate 100.
[0045] In some embodiments, as Figure 4As shown, the part of the support ring plate 100 extending out of the hole 010 is provided with reinforcing ribs 110, and the reinforcing ribs 110 further improve the structural strength of the support ring plate 100 and further improve the supporting capacity.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
