Description

Technical Field

[0001] This invention relates to the field of building technology, and more specifically, to an anti-slip device for the uprights of an external scaffolding with an I-beam cantilever frame. Background Technology

[0002] I-beams are long steel bars with an I-shaped cross-section. The uprights of the cantilevered scaffolding are support structures used to support and fix materials such as exterior wall decorative grids, formwork, and concrete. In actual construction, the uprights of the scaffolding are usually installed on the I-beams using special positioning stakes. The positioning stakes are fixed to the I-beams using bolts and washers, and the uprights are then inserted into the sleeves of the positioning stakes and fixed in the sleeves using connectors.

[0003] A highly efficient and reusable anti-slip device for scaffolding, as described in authorized patent publication number CN219587185U, includes: a support sleeve for connecting to the vertical uprights of the scaffolding; a support pad fixed to the lower end of the support sleeve to level it; a support hook formed by bending downwards from one end of the support pad for support on the ground; and a support foot located at the other end of the support pad, supporting the support pad together with the support hook. A suction cup is provided below the support pad, and a guide rod is provided at the upper end of the suction cup. The guide rod is slidably sleeved with a pressure tube, which passes through the support pad. A second nut is fixed to the support pad, and the pressure tube is threadedly connected to the second nut. The pressure tube moves up and down by rotation, pressing the suction cup tightly against the support surface. This invention resists ground slippage without welding, is easy to disassemble, and is reusable.

[0004] However, the current anti-slip effect of the positioning piles is poor. The positioning pile is fixed to the I-beam by a bolt and a washer. The single washer contacts the I-beam, which makes the overall contact area between the positioning pile and the I-beam small. The aforementioned patent also adds a suction cup, but the suction force of the suction cup cannot play an effective anti-slip role. As a result, the positioning pile is easy to slide on the I-beam under the action of external force, which makes it impossible for the scaffolding upright to be stably fixed to the I-beam.

[0005] In view of this, this application proposes an anti-slip device for the uprights of an external scaffolding with an I-beam cantilever frame. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention proposes an anti-slip device for the uprights of an external scaffolding with an I-beam cantilever frame.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an anti-slip device for the uprights of an external scaffolding with an I-beam cantilever structure, comprising a U-shaped pad and a sleeve disposed on top of the U-shaped pad, wherein the U-shaped pad is disposed on the top of the I-beam, and the two sides of the U-shaped pad are located on both sides of the I-beam, and an upright is disposed inside the sleeve, and further comprising:

[0008] An anti-slip assembly is installed on the U-shaped pad to prevent the U-shaped pad and the upright from sliding on the I-beam.

[0009] A height adjustment component is installed on the sleeve. The height adjustment component is used to adjust the distance from the bottom of the upright to the U-shaped pad, so that the upright can be smoothly fixed in the sleeve.

[0010] An auxiliary anti-slip component is installed on the U-shaped pad to help prevent the U-shaped pad from sliding on the I-beam.

[0011] An abutment assembly is installed on the U-shaped pad to prevent the U-shaped pad from sliding laterally on the I-beam;

[0012] An angle adjustment component is installed on the U-shaped pad. The angle adjustment component is used to adjust the angle of the sleeve and the upright.

[0013] Furthermore, the anti-slip assembly includes first bolts threaded to the two side walls of the U-shaped pad, one end of each first bolt being rotatably connected to a first contact block facing the vertical surface of the I-beam. Two first guide rods are fixedly connected to the first contact blocks, and the first guide rods slide through the two side walls of the U-shaped pad. Two L-shaped blocks are fixedly connected to the first contact blocks, and the top of each L-shaped block is set as an inclined surface. Two limiting openings are opened on both side walls of the U-shaped pad, and a second guide rod is slidably connected within the limiting openings. Two limiting plates are fixedly connected to the surface of the second guide rods, and the two limiting plates contact the side walls of the U-shaped pad. A first spring is fixedly connected between the second guide rod and the inner wall of the limiting opening. One end of each of the two second guide rods is fixedly connected to a second contact block facing the bottom and top of the I-beam. The second contact block has an inclined surface parallel to the inclined surface of the L-shaped block. A cleaning assembly for cleaning the surface of the I-beam is provided in both the first and second contact blocks.

[0014] Furthermore, the cleaning assembly includes multiple slots formed within the first and second contact blocks. A rod is slidably inserted into each slot. One end of the rod is fixedly connected to a suction cup facing the I-beam, and the other end of the rod is fixedly connected to the slot with a second spring. The first and second contact blocks have storage slots adapted to the suction cup. The first and second contact blocks also have multiple air outlet channels. The slots communicate with two corresponding air outlet channels, and each air outlet channel contains an air outlet assembly for dispersing airflow.

[0015] Furthermore, the air outlet assembly includes a connecting rope fixed to the inner wall of the air outlet channel, one end of the connecting rope being fixed to a connecting ball, the connecting ball having multiple curved channels, a connecting plate being fixed to the connecting ball, a connecting rod being fixed to the inner wall of the air outlet channel, and a stop block being fixed to one end of the connecting rod, which is directly opposite the connecting plate.

[0016] Furthermore, the height adjustment assembly includes shims stacked inside the sleeve and between the upright, one end of the shims being fixedly connected to a connecting piece, the sleeve having a rectangular opening adapted to the connecting piece, a first nut being fixedly connected to the surface of the sleeve, the first nut having a second bolt internally threaded onto it, and the second bolt passing through the rectangular opening and the bottom end of the upright.

[0017] Furthermore, the auxiliary anti-slip assembly includes a horizontal plate disposed at the bottom of the lowest connecting piece, two guide posts that slide through the horizontal plate are fixedly connected to the top of the U-shaped pad, a third spring sleeved on the outside of the guide posts is fixedly connected between the guide posts and the U-shaped pad, two connecting posts are fixedly connected to the bottom of the two horizontal plates, a pressing plate is fixedly connected to the bottom end of the two connecting posts, and a clamping assembly for stabilizing and preventing the U-shaped pad on the I-beam is provided on the U-shaped pad.

[0018] Furthermore, the clamping assembly includes an extrusion plate fixed to the bottom of the pressure plate, the bottom end of the extrusion plate being rounded, and two third guide rods fixed to both sides of the U-shaped pad, with two extrusion rods slidably connected to the third guide rods. Both ends of the extrusion rods are provided with arc surfaces adapted to the rounded bottom end of the extrusion plate. The two sides of the extrusion plate abut against the two extrusion rods, and the two extrusion rods abut against the I-beam and the U-shaped pad, respectively.

[0019] Furthermore, the angle adjustment assembly includes an annular plate fixed to the outer surface of the sleeve, a second nut fixed to the top of the annular plate, a limit bracket fixed to the top of the U-shaped pad, an arc-shaped opening on the limit bracket, a third bolt slidably connected inside the arc-shaped opening, and the third bolt threadedly connected inside the second nut.

[0020] The technical effects and advantages of the anti-slip device for the uprights of an I-beam cantilever scaffolding of an external scaffolding:

[0021] (1) By setting up anti-slip components, when it is necessary to install the U-shaped pad on the I-beam, the U-shaped pad is inserted from one end of the I-beam so that the U-shaped pad reaches the appropriate position. The first bolts on both sides are rotated, and the first bolts drive the first contact blocks on both sides to move towards the middle, so that the two first contact blocks are in close contact with the vertical surface of the I-beam. The first contact blocks drive the second contact blocks to move towards the top and bottom of the I-beam through the L-shaped blocks, so that the second contact blocks are in close contact with the I-beam. This increases the contact area between the U-shaped pad and the I-beam, thereby increasing the friction between the U-shaped pad and the I-beam and thus increasing the anti-slip capability.

[0022] (2) By setting up a cleaning component, when the first contact block or the second contact block is about to contact the I-beam, the suction cup will contact the I-beam first. The I-beam will press the suction cup, pressing the insertion rod at the rear end of the suction cup into the slot. The second spring is compressed, and the suction cup is pressed into the storage slot. The suction cup is tightly attached to the surface of the I-beam, further enhancing the anti-slip effect. The compressed air in the slot is discharged through the air outlet channel. When the wind passes through the air outlet channel, the connecting ball is blown up, making the connecting plate located directly behind the stop block. Under the action of gravity, the connecting ball will fall. Under the action of gravity and wind, the connecting ball will swing freely with the wind. The wind can be discharged from the curved channel or the gap between the connecting ball and the air outlet channel, making the discharged wind disordered and able to blow in all directions, blowing away the impurities on the surface of the I-beam, preventing the impurities from affecting the contact between the first contact block and the second contact block and the I-beam, thereby reducing the friction.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Reference Figure 1 and Figure 2 A device for preventing slippage of the uprights of an external scaffolding with a cantilevered structure on an I-beam includes a U-shaped pad 1 and a sleeve 2 disposed on top of the U-shaped pad 1. The U-shaped pad 1 is disposed on the top of the I-beam, with its two sides located on both sides of the I-beam. An upright is disposed inside the sleeve 2. The device also includes:

[0039] An anti-slip component is provided on the U-shaped pad 1 to prevent the U-shaped pad 1 and the upright from sliding on the I-beam;

[0040] A height adjustment component is provided on the sleeve 2. The height adjustment component is used to adjust the distance from the bottom end of the upright to the U-shaped pad 1 so that the upright can be smoothly fixed in the sleeve 2.

[0041] An auxiliary anti-slip component is provided on the U-shaped pad 1 to help prevent the U-shaped pad 1 from sliding on the I-beam;

[0042] A clamping component is provided on the U-shaped pad 1 to prevent the U-shaped pad 1 from sliding laterally on the I-beam;

[0043] An angle adjustment component is installed on the U-shaped pad 1. The angle adjustment component is used to adjust the angle between the sleeve 2 and the upright. The U-shaped pad 1 is inserted from one end of the I-beam and moved to a suitable position on the I-beam. The U-shaped pad 1 is fixed to the I-beam by the anti-slip component. The height of the upright on the sleeve 2 is adjusted by the height adjustment component. The upright is fixed by the reserved hole of the upright. The auxiliary anti-slip component can play an auxiliary anti-slip role after the height adjustment is completed. The clamping component can make the U-shaped pad 1 and the I-beam clamp together to prevent the U-shaped pad 1 from sliding laterally on the I-beam and enhance the overall anti-slip effect of the U-shaped pad 1.

[0044] Reference Figure 2 , Figure 3 and Figure 4The anti-slip assembly includes first bolts 3 threaded to the two side walls of the U-shaped pad 1. One end of each first bolt 3 is rotatably connected to a first contact block 4 facing the vertical surface of the I-beam. Two first guide rods 5 are fixed to the first contact blocks 4, sliding through the two side walls of the U-shaped pad 1. Two L-shaped blocks 6 are fixed to the first contact blocks 4, with the top of each L-shaped block 6 set as an inclined surface. Two limiting openings 7 are provided on both side walls of the U-shaped pad 1. A second guide rod 8 is slidably connected within each limiting opening 7. Two limiting plates 9 are fixed to the surface of the second guide rod 8, contacting the side walls of the U-shaped pad 1. A first spring 10 is fixed between the second guide rod 8 and the inner wall of the limiting opening 7. One end of each of the two second guide rods 8 is fixed to a second contact block 11 facing the bottom and top of the I-beam. The second contact block 11 has an inclined surface parallel to the inclined surface of the L-shaped block 6. 4. Both the first and second contact blocks 11 are equipped with cleaning components for cleaning the surface of the I-beam. When it is necessary to fix the U-shaped pad 1 to the I-beam, rotate the first bolts 3 on both sides. The first bolts 3 drive the first contact blocks 4 on both sides to move towards the I-beam, so that the first contact blocks 4 contact the vertical surface of the I-beam. The first contact blocks 4 drive the L-shaped block 6 to move. The L-shaped block 6 can press the two second contact blocks 11 to move towards the top and bottom of the I-beam respectively through the inclined surface, so that the second contact blocks 11 contact the I-beam. The first contact blocks 4 and the second contact blocks 11 contact the I-beam at the same time, so that the contact area between the U-shaped pad 1 and the I-beam is larger, increasing the friction between the U-shaped pad 1 and the I-beam, thereby enhancing the anti-slip effect. When it is necessary to remove the U-shaped pad 1 from the I-beam, rotate the first bolts 3 in the opposite direction, so that the first contact blocks 4 and the second contact blocks 11 leave the surface of the I-beam, release the fixation, and the U-shaped pad 1 can be removed. The U-shaped pad 1 and the anti-slip components can be reused.

[0045] Reference Figure 5 and Figure 6The cleaning assembly includes multiple slots 12 formed within the first contact block 4 and the second contact block 11. A rod 13 is slidably inserted into each slot 12. One end of the rod 13 is fixedly connected to a suction cup 14 facing the I-beam, and the other end of the rod 13 is fixedly connected to the slot 12 with a second spring 15. The first contact block 4 and the second contact block 11 have storage slots 16 adapted to the suction cup 14. The first contact block 4 and the second contact block 11 also have multiple air outlet channels 17. Each slot 12 communicates with two corresponding air outlet channels 17. Each air outlet channel 17 contains an air outlet assembly for dispersing airflow. Before the first contact block 4 and the second contact block 11 contact the I-beam, the suction cup 14... When the first contact block 4 and the second contact block 11 come into contact with the I-beam, the I-beam will press the suction cup 14 into the receiving groove 16, so that the suction cup 14 will not be clamped between the contact block and the I-beam. The suction cup 14 can adhere to the surface of the I-beam, further enhancing the anti-slip effect. The suction cup 14 can drive the insertion rod 13 to be inserted into the slot 12. The second spring 15 is compressed, and the insertion rod 13 can force the air in the slot 12 into the air outlet channel 17. The air will be discharged from the air outlet channel 17 and blown towards the I-beam. It can blow air onto the surface of the I-beam before the first contact block 4 and the second contact block 11 come into contact with the I-beam, blowing away the impurities attached to the surface of the I-beam, preventing the presence of impurities between the first contact block 4 and the second contact block 11 and the I-beam, which would cause slippage and affect the anti-slip effect.

[0046] Reference Figure 7 The air outlet assembly includes a connecting rope 18 fixed to the inner wall of the air outlet channel 17. One end of the connecting rope 18 is fixed to a connecting ball 19. The connecting ball 19 has multiple curved channels 20 inside. A connecting plate 21 is fixed to the connecting ball 19. A connecting rod 22 is fixed to the inner wall of the air outlet channel 17. One end of the connecting rod 22 is fixed to a stop 23 facing the connecting plate 21. When air is discharged from the air outlet channel 17, the air passes through the connecting ball 19 and blows onto the connecting plate 21 of the connecting ball 19. 1. The connecting plate 21 and the connecting ball 19 are blown up around one end of the connecting rope 18. The connecting plate 21 is blown behind the stop block 23. Under the action of gravity, the connecting ball 19 falls back down. The connecting ball 19 will repeat this action under the action of wind and gravity. The wind will be discharged from the curved channel 20 inside the connecting ball 19 and the gap between the connecting ball 19 and the air outlet channel 17, making the discharged wind more disordered. This allows the wind to blow more disorderedly toward the I-beam, which can radiate a larger area and blow away the impurities on the surface of the I-beam.

[0047] Reference Figure 1 , Figure 8 and Figure 9The height adjustment assembly includes shims 24 stacked inside the sleeve 2 and between the sleeve and the upright. One end of each shim 24 is fixedly connected to a connecting piece 25. The sleeve 2 has a rectangular opening 26 adapted to the connecting piece 25. A first nut 28 is fixedly connected to the surface of the sleeve 2. A second bolt 27 is threaded into the first nut 28. The second bolt 27 passes through the rectangular opening 26 and the bottom end of the upright. When it is necessary to insert and fix the bottom end of the upright into the sleeve 2, shims 24 are added or removed from the rectangular opening 26 into the sleeve 2 according to the position and height of the reserved hole at the bottom end of the upright, so that one end of the shim 24 extends out of the rectangular opening 26. The upright is inserted into the sleeve 2 and placed on top of the shim 24. The second bolt 27 passes through the reserved hole and is threaded into the first nut 28 to fix the upright in the sleeve 2.

[0048] Reference Figure 8 The auxiliary anti-slip assembly includes a horizontal plate 29 disposed at the bottom of the lowest connecting piece 25. Two guide posts 30, which slide through the horizontal plate 29, are fixedly connected to the top of the U-shaped pad 1. A third spring 31, sleeved on the outside of the guide post 30, is fixedly connected between the guide post 30 and the U-shaped pad 1. Two connecting posts 32 are fixedly connected to the bottom of the two horizontal plates 29. A pressure plate 33 is fixedly connected to the bottom end of the two connecting posts 32. The U-shaped pad 1 is provided with a mechanism for stabilizing the U-shaped pad 1. The clamping assembly prevents slippage on the I-beam. After the upright is fixed inside the sleeve 2, the lowest pad 24 can press down on the horizontal plate 29 through the connecting piece 25. The horizontal plate 29 drives the pressure plate 33 to move downward through the connecting column 32. The third spring 31 is compressed, so that the pressure plate 33 is in close contact with the top of the I-beam, which plays an auxiliary role in preventing slippage. When it is necessary to remove the U-shaped pad 1, the horizontal plate 29 and the pressure plate 33 move upward under the action of the third spring 31, and can be removed.

[0049] Reference Figure 10 and Figure 11 The clamping assembly includes a pressing plate 34 fixed to the bottom of the pressing plate 33. The bottom end of the pressing plate 34 is rounded. Two third guide rods 35 are fixed to both sides of the U-shaped pad 1. Two pressing rods 36 are slidably connected to the third guide rods 35. Both ends of the pressing rods 36 are provided with arc surfaces 37 that are adapted to the rounded bottom end of the pressing plate 34. The two sides of the pressing plate 34 abut against the two pressing rods 36. The two pressing rods 36 abut against the I-beam and the U-shaped pad 1, respectively. During the downward movement of the pressing plate 33, the pressing plate 33 presses the arc surfaces 37 on both sides of the two pressing rods 36 through the rounded bottom end of the pressing plate 34, causing the two pressing rods 36 to move to both sides and contact the side walls of the I-beam and the U-shaped pad 1, respectively, thus clamping and fixing the U-shaped pad 1 to the I-beam and preventing the U-shaped pad 1 from sliding laterally.

[0050] Reference Figure 8 and Figure 12 The angle adjustment assembly includes an annular plate 38 fixed to the outer surface of the sleeve 2. A second nut 39 is fixed to the top of the annular plate 38. A limiting bracket 40 is fixed to the top of the U-shaped pad 1. An arc-shaped opening 41 is provided on the limiting bracket 40. A third bolt 42 is slidably connected in the arc-shaped opening 41. The third bolt 42 is threaded into the second nut 39. When it is necessary to adjust the angle of the upright, the third bolt 42 is released and unscrewed from the second nut 39. The annular plate 38 can then be rotated, which can drive the sleeve 2 and the second nut 39 to rotate. The sleeve 2 drives the upright to rotate. When the upright is rotated to a suitable angle, the third bolt 42 is slid in the arc-shaped opening 41 so that the third bolt 42 is aligned with the second nut 39 and screwed in to fix the sleeve 2.

[0051] Working principle: The U-shaped pad 1 is inserted into one end of the I-beam. The U-shaped pad 1 is moved to a suitable position on the I-beam. The anti-slip component fixes the U-shaped pad 1 to the I-beam. The height adjustment component adjusts the position of the upright on the sleeve 2. The upright is fixed through the pre-drilled hole. The auxiliary anti-slip component assists in preventing slippage after height adjustment. The clamping component ensures tightness between the U-shaped pad 1 and the I-beam, preventing lateral slippage and enhancing the overall anti-slip effect. When it is necessary to fix the U-shaped pad 1 to the I-beam, the first bolts 3 on both sides are rotated. The first bolts 3 drive the first contact blocks 4 on both sides to move towards the I-beam, causing the first contact blocks 4 to... The first contact block 4 contacts the vertical surface of the I-beam. The first contact block 4 drives the L-shaped block 6 to move. The L-shaped block 6 can press the two second contact blocks 11 to move towards the top and bottom of the I-beam respectively through the inclined surface, so that the second contact blocks 11 contact the I-beam. The first contact block 4 and the second contact block 11 contact the I-beam at the same time, so that the contact area between the U-shaped pad 1 and the I-beam is larger, increasing the friction between the U-shaped pad 1 and the I-beam, thereby enhancing the anti-slip effect. When it is necessary to remove the U-shaped pad 1 from the I-beam, rotate the first bolt 3 in the opposite direction to make the first contact block 4 and the second contact block 11 leave the surface of the I-beam, release the fixation, and the U-shaped pad 1 can be removed. The U-shaped pad 1 and the anti-slip component can be reused. Before the first contact block 4 and the second contact block 11 contact the I-beam, the suction cup 14 contacts the I-beam first. The I-beam will press the suction cup 14, forcing it into the receiving groove 16, preventing the suction cup 14 from being trapped between the contact block and the I-beam. The suction cup 14 can adhere to the surface of the I-beam, further enhancing the anti-slip effect. The suction cup 14 can drive the insertion rod 13 into the slot 12, compressing the second spring 15. The insertion rod 13 can force the air in the slot 12 into the air outlet channel 17, and the air will be discharged from the air outlet channel 17 and blown towards the I-beam. This can blow air onto the surface of the I-beam before the first contact block 4 and the second contact block 11 contact it, blowing away impurities attached to the surface of the I-beam and preventing the first contact block 4 and the second contact block 11 from contacting the I-beam. Impurities between block 4 and the second contact block 11 and the I-beam cause slippage, affecting the anti-slip effect. When the wind is discharged from the air outlet 17, it passes through the connecting ball 19 and blows on the connecting plate 21 of the connecting ball 19, causing the connecting plate 21 and the connecting ball 19 to be blown up around one end of the connecting rope 18. The connecting plate 21 is blown behind the stop block 23. Under the action of gravity, the connecting ball 19 falls back again. The connecting ball 19 will repeat this action under the action of wind and gravity. The wind will be discharged from the curved channel 20 inside the connecting ball 19 and the gap between the connecting ball 19 and the air outlet 17, making the discharged wind more chaotic and disorderly. This allows the wind to blow more disorderly towards the I-beam, which can radiate a larger area and blow away the impurities on the surface of the I-beam.When the bottom end of the upright needs to be inserted and fixed in the sleeve 2, according to the position and height of the reserved hole at the bottom end of the upright, add or remove shims 24 from the rectangular opening 26 into the sleeve 2, so that one end of the shim 24 extends out of the rectangular opening 26. Insert the upright into the sleeve 2 and place it on top of the shim 24. The second bolt 27 passes through the reserved hole and is threaded into the first nut 28 to fix the upright in the sleeve 2. After the upright is fixed in the sleeve 2, the bottom shim 24 can press down on the horizontal plate 29 through the connecting piece 25. The horizontal plate 29 drives the pressure plate 33 to move downward through the connecting column 32. The third spring 31 is compressed, so that the pressure plate 33 is in close contact with the top of the I-beam, which plays an auxiliary role in preventing slippage. When it is necessary to remove the U-shaped shim 1, under the action of the third spring 31, the horizontal plate 29 and the pressure plate 33 can be removed by moving upwards; during the downward movement of the pressure plate 33, the pressure plate 33 presses the arc surfaces 37 on both sides of the two extrusion rods 36 through the round head at the bottom of the extrusion plate 34, causing the two extrusion rods 36 to move to both sides, so that the extrusion rods 36 contact the side walls of the I-beam and the U-shaped pad 1 respectively, and firmly fix the U-shaped pad 1 to the I-beam to prevent the U-shaped pad 1 from sliding laterally; when it is necessary to adjust the angle of the upright, release the third bolt 42, unscrew the third bolt 42 out of the second nut 39, and then rotate the ring plate 38. The ring plate 38 can drive the sleeve 2 and the second nut 39 to rotate. The sleeve 2 drives the upright to rotate.
