Description

Technical Field

[0001] This utility model relates to a reusable cantilevered protective device for ultra-high-rise buildings. Background Technology

[0002] Currently, the exterior facade of the project is mainly constructed using scaffolding and suspended platforms. When a super high-rise building has a complex facade design, a tight schedule, and requires overlapping construction work on different floors, protective devices need to be installed on the facade. Existing protective devices for super high-rise cantilevered structures are generally temporarily erected using scaffolding. However, in actual use, this can affect the work on the upper and lower facades using suspended platforms for curtain wall and painting, causing certain inconveniences. Furthermore, the scaffolding cannot be effectively fixed after dismantling. Moreover, the connection nodes between the protective device and the connecting structure lack further protective structures, which may cause instability in the protective device. Utility Model Content

[0003] This invention provides a reusable cantilevered protective device for ultra-high-rise buildings, which can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] A reusable cantilevered protective device for ultra-high-rise buildings, including

[0006] A first concrete slab and a second concrete slab; a steel mesh frame set on the second concrete slab; a circular steel pipe set on one side of the steel mesh frame; a first embedded part set on the top of the first concrete slab; a steel wire rope set between the first concrete slab and the second concrete slab; and buckles set at both ends of the steel wire rope for clamping and limiting the steel wire rope and the first embedded part.

[0007] A second embedded part is provided on the second concrete slab and is used to limit and clamp the circular steel pipe; the second embedded part includes a positioning block, a fixing block provided on both sides of the positioning block, a second U-shaped ring provided between the two positioning blocks, and a damping structure provided in the second U-shaped ring and playing a damping role.

[0008] The beneficial effects of this utility model are:

[0009] (1) This utility model achieves a significant enhancement in the overall stability and deformation resistance of the structure by rationally configuring the first concrete slab, the second concrete slab, the steel grid frame, the circular steel pipe, the steel wire rope, the embedded parts, and the damping structure. When subjected to external forces such as wind loads and seismic loads, the steel wire rope can provide additional tension to balance the force and prevent the structure from undergoing excessive deformation or damage; at the same time, the damping structure in the second embedded part can effectively absorb vibration energy, reduce the sway amplitude of the structure, and improve the dynamic stability of the structure, thereby ensuring the efficient operation and safety performance of the structure in complex environments and extending the service life of the structure.

[0010] (2) By adding a clamping structure and a pressure-resistant buffer structure, this utility model significantly improves the stability and vibration reduction performance of the structure under external force. The clamping ring in the clamping structure can effectively fix the circular steel pipe and prevent it from shifting or sliding when the steel grid frame is tilted. The clamping arm, through the movable design of the clearance groove and the second bolt, avoids the fracture caused by excessive rigidity, thus enhancing the reliability and durability of the structure. The pressure-resistant buffer structure provides a multi-level elastic buffer and energy dissipation mechanism through the synergistic effect of the central pressure rod, the compression spring, the rubber block and the damping particles. When the structure is subjected to external force, the movement of the central pressure rod not only compresses the compression spring to provide initial buffer, but also enhances the rigidity by pushing the first rod and the second rod. At the same time, the internal friction of the rubber block and the damping particles further absorbs the vibration energy, ensuring the stability and vibration reduction performance of the structure under external force, thereby improving the stability and reliability of the entire structure.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0027] Example 1

[0028] Reference Figure 1-3 As shown, a reusable cantilevered protective device for ultra-high-rise buildings includes...

[0029] A first concrete slab 1 and a second concrete slab 2; a steel mesh frame 3 disposed on the second concrete slab 2; a circular steel pipe 6 disposed on one side of the steel mesh frame 3; a first embedded part 4 disposed on the top of the first concrete slab 1; a steel wire rope 5 disposed between the first concrete slab 1 and the second concrete slab 2; and buckles 50 disposed at both ends of the steel wire rope 5 for clamping and limiting the steel wire rope 5 and the first embedded part 4.

[0030] The first concrete slab 1 and the second concrete slab 2 serve as the main supporting components, each bearing different loads. The steel grid 3 is installed on the second concrete slab 2, providing structural support and connection, enhancing overall stability and rigidity. The circular steel pipe 6 is installed on one side of the steel grid 3, further enhancing the lateral stability and support capacity of the structure. The first embedded part 4 is installed on the top of the first concrete slab 1, used to connect the steel wire rope 5. The steel wire rope 5 connects the first concrete slab 1 and the second concrete slab 2, providing additional tension when the structure is subjected to external forces (such as wind loads, seismic loads, etc.), balancing the stress on the structure, and preventing excessive deformation or damage. The buckles 50 are installed at both ends of the steel wire rope 5, clamping and limiting the steel wire rope 5 and the first embedded part 4, ensuring that the steel wire rope 5 will not slip or loosen under stress, guaranteeing the reliability of the connection. Through the support of the steel grid 3 and the circular steel pipe 6, and the tension balance of the steel wire rope 5, the entire structure can remain stable when subjected to external forces, enhancing the overall integrity and deformation resistance of the structure, ensuring efficient operation and safety performance in complex environments.

[0031] Furthermore, the steel space frame 3 and the steel wire rope 5 are connected, forming an included angle C, where 30°≤C≤60°. In one embodiment, to ensure the stability of the entire structure, A is approximately 45°. When the included angle C is 45°, the tension provided by the steel wire rope 5 is more balanced in both the horizontal and vertical directions, effectively balancing the forces on the structure in different directions, enhancing overall stability. At this angle, the synergistic effect of the steel space frame 3 and the steel wire rope 5 provides sufficient stiffness to resist deformation caused by external forces, ensuring the stability and reliability of the structure in complex environments. Moreover, at this angle, the tension of the steel wire rope 5 can more effectively transmit and dissipate vibration energy, reducing the sway amplitude of the structure and improving its dynamic stability. In summary, when the included angle C is around 45°, the structural stability is generally good. This angle effectively balances the forces on the structure in different directions, provides sufficient stiffness, dissipates vibration energy, and ensures the stability and reliability of the structure in complex environments.

[0032] The top surface of the first embedded part 4 is provided with a first U-shaped ring 40 and a limiting block 41, a limiting hole 43 formed in the middle of the limiting block 41 and sleeved with the first U-shaped ring 40, and an inclined groove 42 formed on one side of the limiting block 41 and communicating with the limiting hole 43. Before the wire rope 5 is connected to the first U-shaped ring 40, the limiting block 41 is pre-engaged with the first U-shaped ring 40 through the inclined groove 42, and then fixed to the first embedded part 4 by the bolt rod fixing component. Then, the wire rope 5 is also inserted into the limiting hole 43 along the inclined groove 42 and fixed by the buckle 50. This can improve the strength of the first U-shaped ring 40, prevent the first U-shaped ring 40 from being subjected to large forces and bending, and ensure the safety of the structure during use.

[0033] A second embedded part 7 is provided on the second concrete slab 2 and is used to limit and clamp the circular steel pipe 6; the second embedded part 7 includes a positioning block 70, a fixing block 71 provided on both sides of the positioning block 70, a second U-shaped ring 72 provided between the two positioning blocks 70, and a damping structure provided in the second U-shaped ring 72 and providing a damping effect; the second U-shaped ring 72 is divided into a first segment 720 and a second segment 721; wherein, an adjusting rod 7200 is provided at one end of the first segment 720; the second segment 721 has a first cavity 7211 inside; the damping structure includes a second cavity 7212 provided in the first cavity 7211, a damping liquid 7213 provided in the second cavity 7212, a partition 7214 provided in the second cavity 7212 and used to block the damping liquid 7213, a channel 7215 provided on the partition 7214, and a triangular pad 7217 provided on the second cavity 7212.

[0034] The second cavity 7212 also has an inclined portion 7216 to facilitate the flow of the damping fluid 7213.

[0035] The outer wall of the second segment 721 is provided with a first bolt 7210, which is connected to the adjusting rod 7200 to adjust the limiting space of the second U-shaped ring 72.

[0036] The second embedded part 7 fixes the circular steel pipe 6 to the second concrete slab 2 through the positioning block 70 and the fixing block 71. The first segment 720 and the second segment 721 of the second U-shaped ring 72 play supporting and adjusting roles, respectively. The adjusting rod 7200 is used to adjust the tension of the U-shaped ring. The damping structure in the second segment 721 flows through the damping fluid 7213 in the second cavity 7212. The fluid generates viscous force through the channel 7215 on the partition 7214 to absorb vibration energy. The inclined part 7216 promotes the flow of damping fluid. The triangular pad 7217 provides additional support, which together ensures the stability of the structure and the vibration reduction effect.

[0037] Furthermore, the adjusting rod 7200 and the first cavity 7211 can be disassembled, so that after the adjusting rod 7200 is stretched outward, the first bolt 7210 can fix the adjusting rod 7200 and the second segment 721, thereby accommodating circular steel pipes 6 of different thicknesses.

[0038] Example 2

[0039] Reference Figure 4-5 As shown, a reusable cantilevered protective device for ultra-high-rise buildings.

[0040] The difference between this embodiment and the previous embodiment is that a clamping structure 8 is also provided between the two positioning blocks 70. The clamping structure 8 includes a third U-shaped ring 80, a square plate 81 symmetrically arranged on the third U-shaped ring 80, a clamping arm 82 arranged on the square plate 81, a second bolt 84 arranged between the square plate 81 and the clamping arm 82, a clearance groove 83 formed at the first end of the clamping arm 82 and used to make way for the second bolt 84, and a clamping ring 85 arranged at the second end of the clamping arm 82.

[0041] When the steel space frame 3 is subjected to force, the steel space frame 3 with one end of the circular steel pipe 6 will tilt up. After tilting up, in order to prevent the circular steel pipe 6 from shifting or sliding back and forth due to friction, the circular steel pipe 6 is clamped by the clamping ring 85. The clamping arm 82 can move through the relief groove 83 and the second bolt 84, so that the clamping arm 82 has room to move and avoids the clamping arm 82 from breaking due to excessive rigidity.

[0042] The third U-shaped ring 80 is provided with a pressure-resistant buffer structure 9 in the middle; the pressure-resistant buffer structure 9 includes a central pressure rod 90, a protrusion 91 disposed on the top surface of the third U-shaped ring 80 and connected to the central pressure rod 90, an extension end 900 disposed at one end of the central pressure rod 90, a compression spring 901 disposed between the central pressure rod 90 and the protrusion 91, a first rod 902 and a second rod 903 disposed between the extension end 900 and the protrusion 91, and a rubber block 904 disposed inside the extension end 900 and connected to the second rod 903.

[0043] The first rod 902 and the second rod 903 together form a telescopic component. When subjected to force, the telescopic component will extend and retract. However, due to the compression spring 901 and the rubber block 904, the telescopic component is limited, so that the second rod 903 cannot extend and retract to the bottom of the first rod 902. While ensuring that the central pressure rod 90 can play a role in resisting pressure and buffering, the first rod 902 and the second rod 903 improve the strength of the central pressure rod 90 and avoid the risk of it breaking.

[0044] A rubber column 905 is provided at the middle of one end of the central pressure rod 90, an extrusion end 906 is provided at one end of the rubber column 905, a first wave pad 907 is provided on the extrusion end 906, and damping particles 908 are filled inside the first wave pad 907.

[0045] The inner top surface of the protrusion 91 is provided with a second wave pad 910 corresponding to the first wave pad 907.

[0046] When the structure is subjected to external force, the central pressure bar 90 moves downward, compressing the compression spring 901 and providing initial elastic cushioning. Simultaneously, the extended end 900 of the central pressure bar 90 pushes the first rod 902 and the second rod 903, further enhancing the rigidity of the structure. A rubber block 904 is disposed inside the extended end 900 and connected to the second rod 903, providing additional elastic cushioning. A rubber column 905 is located in the middle of one end of the central pressure bar 90, and a compression end 906 is located at one end of the rubber column 905. A first wave pad 907 is provided on the compression end 906, which is filled with damping particles 908. When the central pressure bar 90 moves downward, the rubber column 905 and the compression end 906 push the first wave pad 908. 07. The internal damping particles 908 generate internal friction to absorb and dissipate vibration energy. The inner top surface of the protrusion 91 is provided with a second wave pad 910 corresponding to the first wave pad 907. When the first wave pad 907 is compressed, it comes into contact with the second wave pad 910, further enhancing the damping effect and ensuring the stability and shock absorption performance of the structure when subjected to external forces. Through this design, the compression buffer structure 9 not only provides elastic buffering, but also effectively absorbs and dissipates vibration energy through the internal friction of the damping particles 908, thereby improving the stability and reliability of the entire structure.

[0047] This embodiment mainly addresses the issue that after the circular steel pipe 6 warps up, the structural compression buffer provided by this embodiment can improve the dynamic stability of the structure, reduce fatigue damage caused by vibration, and extend the service life of the structure.
