AI Technical Summary
In existing technologies, the tie ropes of the I-beams of the cantilevered scaffold are prone to slippage, making it impossible to unload the load. Furthermore, the commonly used welding fixing method is wasteful of materials, dangerous, difficult to operate, and the quality is hard to guarantee.
It adopts an I-beam with an insert fastener, combined with a buffer rubber pad and a slider structure. The fastener is connected to the I-beam by bolts. The friction between the rope groove and the slider prevents the rope from slipping. It is also detachable and reusable.
This method achieves stable fixation of the I-beams of the cantilevered scaffolding with ropes, reducing labor intensity, saving costs, and improving aesthetics and safety.

[0030] Please see Figures 1 to 7 The present invention provides a technical solution: a cantilevered scaffold I-beam rope fixing device, comprising: an I-beam 2 and a rope 23, a fixing member 8 is inserted into one end of the I-beam 2, a buffer rubber pad 12 is installed at the lower end of the fixing member 8 by bolts, a plurality of rope grooves 14 are evenly opened on the lower side wall of the buffer rubber pad 12, the rope grooves 14 are semi-circular, the rope 23 is firmly installed on the semi-circular rope grooves 14 on the buffer rubber pad 12, and the angle of the rope can be adjusted according to different requirements, sliders 17 are provided on both the left and right sides of the upper end of the fixing member 8, the sliders 17 are slidably connected to the upper side wall of the I-beam 2, the sliders 17 and the fixing member 8 are threadedly connected, and a structural frame 7 is installed at the upper end of the I-beam 2;
[0031] The other end of the I-beam 2 is installed on the concrete structure 1 through a fixing anchor 4. Several pre-embedded bolts 3 are provided at the upper end of the concrete structure 1. The upper end of the pre-embedded bolts 3 protrudes out of the outer side of the upper end of the concrete structure 1. One end of the I-beam 2 is inserted between two pre-embedded bolts 3. The fixing anchor 4 is U-shaped and is fitted on the upper end of the I-beam 2. A base plate 5 is fixedly welded to the lower end of the fixing anchor 4. Bolt holes are opened on the base plate 5. The base plate 5 is fitted on the upper end of the pre-embedded bolts 3 through the bolt holes and is threaded with nuts, thus fixing the other end of the I-beam 2 to the upper end of the concrete structure 1. A rope anchor ring 6 is fixedly installed at the upper end of the concrete structure 1 located above the I-beam 2. The two ends of the rope 23 are fixed on the rope anchor ring 6, and the middle part of the rope 23 is located in the rope groove 14.
[0032] The inner side of the fastener 8 is provided with a convex insertion groove 9. The size of the insertion groove 9 is larger than the size of the lower outer wall of the I-beam 2. An anti-slip pad 10 is fixedly installed on the inner wall of the bottom end of the insertion groove 9. The inner wall of the insertion groove 9 is slidably connected to the lower side wall of the outer end of the I-beam 2. The anti-slip pad 10 is in contact with the side wall of the outer end of the I-beam 2, increasing the friction between the fastener 8 and the I-beam 2.
[0033] Threaded holes 11 are provided on the four side walls of the lower end of the fastener 8. Through holes 13 are provided on the four side walls of the buffer rubber pad 12. One end of the bolt passes through the through hole 13 and is threaded to the inner wall of the threaded hole 11 to fix the buffer rubber pad 12 to the lower side wall of the fastener 8. The diameter of the rope groove 14 is larger than the diameter of the pull rope 23. An extension plate 15 is fixedly installed on the lower end side wall of the rope groove 14. The extension plate 15 and the buffer rubber pad 12 are integrally formed. The extension plate 15 can block the pull rope 23 fixed in the rope groove 14 to prevent the pull rope 23 from falling off during the fixing process.
[0034] Threaded cylinders 16 are fixedly installed on the upper left and right side walls of the fastener 8. Slider 17 is located at the upper end of threaded cylinder 16. Slider 17 is U-shaped. Anti-slip pad II 18 is fixedly installed on the upper inner wall of slider 17. Two sliders 17 are slidably connected to the upper outer wall of one end of I-beam 2. Anti-slip pad II 18 increases the friction between I-beam 2 and slider 17. A rotating hole 19 is opened on the lower side wall of each slider 17, penetrating the lower side wall.

The diameter of baffle 21 is larger than the diameter of rotating hole 19. Baffle 21 limits the rotating rod 20, so that when the rotating rod 20 is threadedly connected to the threaded cylinder 16, it rotates in place at the lower end of slider 17, applying an upward pulling force to the fastener 8.
[0035] The lower end of the rotating rod 20 has an external thread, which is connected to the inner wall of the threaded cylinder 16. A fastening nut 22 is also fixedly installed on the outer wall of the rotating rod 20. The fastening nut 22 facilitates connection with the board. By connecting the wrench and the fastening nut 22 and rotating them, the rotating rod 20 rotates inside the threaded cylinder 16. The anti-slip pad 18 at the upper end of the slider 17 is in close contact with the upper end side wall of the I-beam 2. At the same time, the anti-slip pad 10 in the insertion groove 9 is in close contact with the lower end outer wall of the I-beam 2. The fixing part 8 and the buffer rubber pad 12 are fixed to the lower end of the I-beam 2. By reversing the fastening nut 22, the rotating rod 20 rotates in the opposite direction inside the threaded cylinder 16, and the fixing part 8 and the slider 17 can be removed from the I-beam 2. This makes disassembly and assembly convenient and facilitates recycling.
[0036] When this device is in operation, the construction preparation is as follows: → According to the size of the I-beam 2, the steel plate is processed into a fixing part 8. → The bottom of the buffer rubber pad 12 is cut into a semi-circular rope groove 14 that is slightly larger than the diameter of the pull rope 23. → The buffer rubber pad 12 is fixed to the lower end of the fixing part 8 with bolts. → The slider 17 is threaded on the upper end of the fixing part 8. → The fixing part 8 is installed on the cantilevered scaffold I-beam 2. → The pull rope 23 is tied through the semi-circular rope groove 14 of the buffer rubber pad 12. → The installation of the pull rope 23 fixing device is completed.
