Description

Technical Field

[0001] The invention belongs to the technical field of scaffolding windproof structures, and in particular relates to a strong-wind self-unloading cantilever scaffolding windproof buckle structure. Background Art

[0002] Scaffolding is an iron frame structure built on the outside of a house during construction. It is used for construction workers to climb and place construction tools. The outside of the scaffolding must be covered with a layer of safety net to prevent wind and prevent construction workers and construction tools from falling.

[0003] However, in extreme weather, when strong winds blow towards the safety net that completely covers the outer layer of the scaffolding, the wind pressure will exert inward pressure on the safety net. The safety net with a larger force-bearing area will bring about a greater force transfer, causing the safety net and the scaffolding to shake or even fall apart, which will bring great safety hazards. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a strong wind self-unloading cantilever scaffolding windproof buckle structure, which can make the safety net leak air and unload force in strong wind conditions to ensure the safety of the scaffolding.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] The present invention includes four safety net traction devices installed at the four intersection corners of the scaffolding, and the safety net traction device includes a bar shell, and the upper side of the bar shell is provided with a U-shaped hook for hanging on the scaffolding cross bar, and the two legs of the U-shaped hook are supported on the upper and lower sides of the scaffolding cross bar, and the rear side of the bar shell is provided with a U-shaped buckle plate for fixing the bar shell to the vertical bar of the scaffolding, and the U-shaped buckle plate is buckled on the vertical bar and fixedly connected to the rear side of the bar shell; a vertical hole groove is provided in the bar shell, and a sliding block is slidably provided in the hole groove, and a locking portion for buckling the fixing holes at the four corners of the safety net is provided on the side of the sliding block, and a spring is provided between the sliding block and the bottom of the hole groove.

[0007] Furthermore, a plurality of elastic pins are provided around the side surface of the top end of the hole groove, and the elastic pins extend from the side surface of the hole groove. The ends of the elastic pins are in the shape of a hemispherical head. An annular groove is provided in the middle section of the sliding block. When the sliding block is against the top side of the hole groove, the elastic pins are stuck in the annular groove. When the safety net is blown by extreme wind and pulls the sliding block toward the bottom side of the hole groove, the annular groove squeezes the elastic pins so that the elastic pins are retracted into the side surface of the hole groove.

[0008] Furthermore, a vertical groove is provided on the side of the bar shell, and the groove runs through the upper and lower sides of the bar shell. The locking portion includes two parallel plywood extending from the side of the sliding block and a locking stud. A vertical groove leading to the groove is also provided on the front side of the bar shell. The locking stud passes through the vertical groove, the first layer of the plywood and the fixing hole of the safety net, and is threadedly connected to the second layer of the plywood.

[0009] Furthermore, the locking portion also includes a telescopic base, which is laterally slidably arranged on the side of the sliding block, and the two splints are fixed to the side of the telescopic base. An elastic traction member is also provided between the telescopic base and the sliding block.

[0010] Furthermore, an adjusting stud is threadedly connected to the lower side of the bar housing, and the adjusting stud is located at the bottom side of the hole groove and abuts against the end of the spring.

[0011] Furthermore, there are two U-shaped hooks, which are located at two edges of the upper side of the bar shell, and the distance between the two U-shaped hooks is equal to the diameter of the scaffolding vertical rod.

[0012] Furthermore, the U-shaped gusset plate includes two arc-shaped plates, which are hinged to the two edges of the rear side of the bar shell respectively, and the free ends of the two arc-shaped plates are respectively provided with a clamping hole and a clamping piece.

[0013] The beneficial effects of the present invention are:

[0014] The present invention arranges the four corners of the safety net by traction through each group of four safety net traction devices; the four safety net traction devices can be fixed at the intersection of the scaffolding horizontal bars and the scaffolding vertical bars through U-shaped hooks and U-shaped buckle plates. When installing the safety net traction device, it is only necessary to hang the device on the horizontal bars first, and then rotate the device toward the vertical bars, and then buckle the U-shaped buckle plates to the vertical bars. This structure can quickly and conveniently fix the entire device at the staggered position, achieving high efficiency of the installation project; after the safety net traction device is installed, the installation is locked by the locking part By fixing the four corners of the entire net, the safety net can be deployed and arranged in the square frame formed by the staggered scaffolding, effectively protecting and isolating the construction site. Furthermore, by providing springs and sliding blocks, when strong winds blow against the safety net, the surface of the safety net is pressed against the wind. The four corner traction locks and sliding blocks of the safety net overcome the supporting force of the springs and move along the slots, temporarily recessing the safety net into the scaffolding ladder, creating a gap for air to pass through. As the wind decreases, the recess also decreases. This structure is used to reduce the self-unloading force of the safety net in strong winds. When strong winds blow against the safety net, the gap in the safety net opens up, allowing air to circulate, preventing large-scale direct force on the safety net from causing damage to the scaffolding and improving the safety of the scaffolding.

[0025] like Figures 1 to 7 As shown, the present invention discloses a strong wind self-unloading cantilever scaffolding windproof buckle structure, such as Figure 1 As shown, it includes four safety net 9 traction devices installed at the four corners of the scaffolding intersection. The safety net 9 traction device fixes the four corners of the safety net 9 at the intersection of the scaffolding crossbar 81 and the scaffolding vertical bar 82 to straighten the safety net 9; Figure 2 and Figure 3 The safety net 9 traction device includes a bar shell 1, which is a long strip structure and can be made of wear-resistant plastic or lightweight aluminum; a U-shaped hook 2 is provided on the upper side of the bar shell 1 for hanging on the scaffolding crossbar 81, such as Figure 3 As shown, the opening of the U-shaped hook 2 faces the front side of the shell 1. When the shell 1 is hung, the two legs of the U-shaped hook 2 are supported on the upper and lower sides of the scaffolding crossbar 81 to initially limit the upper and lower displacement of the shell 1; Figure 3 As shown, the rear side of the bar housing 1 is provided with a U-shaped gusset plate 3 for fixing the bar housing 1 to the scaffolding vertical rod 82. The U-shaped gusset plate 3 is buckled on the vertical rod and fixedly connected to the rear side of the bar housing 1. The opening of the U-shaped gusset plate 3 faces the rear side of the bar housing 1. By fixing the U-shaped gusset plate 3, the left and right displacement of the bar housing 1 can be limited; Figure 4 As shown, a vertical hole 11 is provided in the housing 1. The hole 11 is a circular hole structure. A cylindrical sliding block 4 is slidably provided in the hole 11. The sliding block 4 moves smoothly in the hole 11. A spring 6 is provided between the sliding block 4 and the bottom of the hole 11. The spring 6 presses the sliding block 4 against the top side of the hole 11. Figure 5 As shown, the side of the sliding block 4 is provided with a locking portion 5 for buckling the fixing holes at the four corners of the safety net 9, Figure 7 The four corners of the safety net 9 are provided with solid round holes, which are convenient for pulling and clamping the four corners of the safety net 9 through the locking portion 5. At this time, the safety net 9 can be opened and arranged on the staggered scaffolding.

[0026] The scaffolding windproof buckle structure mainly uses each group of four safety net 9 traction devices to pull and arrange the four corners of the safety net 9; the four safety net 9 traction devices can be fixed at the intersection of the scaffolding crossbar 81 and the scaffolding vertical bar 82 through the U-shaped hook 2 and the U-shaped buckle plate 3. When installing the safety net 9 traction device, you only need to hang the device on the crossbar first, then rotate the device toward the vertical bar, and then buckle the U-shaped buckle plate 3 to the vertical bar. This structure can quickly and conveniently fix the entire device in the staggered position, achieving high efficiency of the installation project; after the safety net 9 traction device is installed, it can be fixed by locking it. By fixing the four corners of the safety net 9 with the parts 5, the safety net 9 can be opened and arranged in the square frame formed by the staggered scaffolding to effectively protect and isolate the construction site. In addition, by providing springs 6 and sliding blocks 4, when strong winds blow towards the safety net 9, the surface of the safety net 9 is pressed by the wind. The four corner traction lock parts 5 and sliding blocks 4 of the safety net 9 overcome the supporting force of the springs 6 and move along the slots 11. The safety net 9 temporarily sinks into the inside of the scaffolding ladder, forming a gap for air to pass through. When the wind force decreases, the depression also decreases. This structure is used to reduce the self-unloading force of the safety net 9 in strong winds. When strong winds blow towards the safety net 9, the safety net 9 opens a gap, allowing air to circulate, avoiding direct force on a large area of ​​the safety net 9, which may cause damage to the scaffolding, thereby improving the safety of the scaffolding.

[0027] In a further solution, Figure 4 and Figure 5 As shown, four elastic pins 12 are provided around the side surface of the top end of the hole groove 11, and the elastic pins 12 extend from the side surface of the hole groove 11. The end of the elastic pin 12 is in the shape of a hemispherical head. The middle section of the sliding block 4 is provided with an annular groove 41. When the sliding block 4 is against the top side of the hole groove 11, the elastic pin 12 is stuck in the annular groove 41. When the safety net 9 is blown by extreme wind and pulls the sliding block 4 toward the bottom side of the hole groove 11, the annular groove 41 squeezes the elastic pin 12, so that the elastic pin 12 is retracted into the side surface of the hole groove 11.

[0028] This structure is used to reduce the impact of wind on the safety net 9. Only in strong wind conditions, when the pulling force of the safety net 9 is too large, the blocking force of the elastic pin 12 is overcome, the elastic pin 12 is retracted, the sliding block 4 moves, and the safety net 9 is dented. Under this structure, the safety net 9 will not sag in a relatively safe weak wind condition, avoiding frequent sags of the safety net 9, which may lead to the safety net 9 being unable to isolate dust and protect construction workers.

[0029] In a further solution, Figure 3 and Figure 5As shown, a vertical groove 13 is provided on the side of the bar housing 1, and the groove 13 runs through the upper and lower sides of the bar housing 1. The locking portion 5 includes two parallel plywood 51 extending from the side of the sliding block 4 and a locking stud 52. The front side of the bar housing 1 is also provided with a vertical groove 14 leading to the groove 13. The locking stud 52 passes through the vertical groove 14, the first layer of the plywood 51 and the fixing hole of the safety net 9, and is threadedly connected to the second layer of the plywood 51.

[0030] In this structure, the groove 13 is used to limit and guide the two plywood 51, and the groove 13 that passes through the upper and lower parts can make way for the safety net 9, so that the safety net 9 can move smoothly in the groove 13. The vertical groove 14 is used to make way for the locking stud 52. By setting the structure of the locking stud 52 and the two plywood 51, it is convenient to fix the four corners of the safety net 9 after the safety traction device is fixed: directly insert the traction hole 91 of the safety net 9 between the two plywood 51, and then tighten the locking stud 52. This structure facilitates the fixation of the four corners of the safety net 9, avoids the excessive dispersion of parts, and realizes the rapid installation of the safety net 9.

[0031] In a further solution, Figure 5 As shown, the locking portion 5 also includes a telescopic base 53, which is laterally slidably arranged on the side of the sliding block 4, and the two splints 51 are fixed to the side of the telescopic base 53. An elastic traction member 54 is also provided between the telescopic base 53 and the sliding block 4.

[0032] Under the traction of the elastic traction member 54, the telescopic base 53 moves toward the inside of the sliding block 4. When the four corners of the safety net 9 are fixed on the locking part 5, the safety net 9 is pulled horizontally by the elastic traction machine, which is conducive to ensuring the flatness of the safety net 9.

[0033] In a further solution, Figure 4 As shown, an adjusting stud 7 is threadedly connected to the lower side of the bar housing 1 , and the adjusting stud 7 is located at the bottom side of the hole slot 11 and abuts against the end of the spring 6 .

[0034] This structure is used to adjust the supporting capacity of the spring 6 on the sliding member, adjust the effect of wind force on the deformation of the safety net 9, and is also used to facilitate the replacement of failed springs 6.

[0035] In a further solution, Figure 2 and Figure 3 As shown, there are two U-shaped hooks 2 , which are located at two edges of the upper side of the bar housing 1 , and the distance between the two U-shaped hooks 2 is equal to the diameter of the scaffolding vertical rod 82 .

[0036] This structure can effectively limit the lateral displacement of the traction device of the safety net 9 at the intersection of the horizontal rod and the vertical rod, and is used for positioning the traction device of the safety net 9.

[0037] In a further solution, Figure 5 and Figure 6 The U-shaped buckle plate 3 includes two arc-shaped plates 31, which are hinged to the two edges of the rear side of the bar shell 1 respectively, and the free ends of the two arc-shaped plates 31 are respectively provided with a card hole 32 and a card member 33.

[0038] This structure is connected to the rear side of the bar shell 1, and the U-shaped gusset plate 3 is buckled on the scaffolding vertical rod 82 through rotation and snap-on connection. The U-shaped gusset plate 3 of this structure is integrally connected to the bar shell 1, which is easy to lock and facilitates high-altitude operations to prevent parts from falling.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
