Description

Technical Field

[0001] This utility model relates to the field of wall tie technology, and in particular to a scaffolding tool-type wall tie that is resistant to high wind pressure. Background Technology

[0002] As a core load-bearing component of the scaffolding system, wall ties firmly connect the scaffolding to the building structure, forming a unified whole to resist horizontal external forces such as wind loads, ensuring the overall stability and safety of the scaffolding. Especially in high-rise building construction, where the scaffolding bears immense wind pressure, the connection strength and stability of the wall ties directly affect the safety of construction workers and the smooth progress of the project, serving as a crucial safety guarantee against scaffolding overturning and collapsing.

[0003] In existing scaffolding projects, wall ties are typically installed using either rigid or flexible connections. A rigid connection's mechanical structure mainly consists of a connecting steel pipe, couplers at both ends, and short steel rings or bolts embedded in the wall structure. The technical principle is that one end of the connecting steel pipe is locked to the scaffold upright using couplers, while the other end passes through a pre-drilled hole in the wall or connects to an embedded component via another coupler, forming a rigid support. Flexible connections usually use double-strand steel wire ropes, which are used to bind and tie the scaffolding to the building by passing through the wall or around structural columns. The technical principle is to utilize the tensile strength of the steel wire ropes to restrain the scaffolding and prevent it from tilting outwards.

[0004] However, the aforementioned traditional connection methods generally suffer from cumbersome and inconvenient procedures when installing scaffolding and walls. Whether using rigid connections with steel pipe couplers or flexible connections with steel wire ropes, the installation process is extremely complicated. Workers need to perform positioning, pipe threading, tightening multiple bolts, or complex binding operations at heights. This is not only labor-intensive and time-consuming but also heavily reliant on worker skill and responsibility, resulting in low installation efficiency. This multi-step, non-standardized installation method not only increases the complexity of construction and the risks of working at heights but also makes it difficult to guarantee the consistent quality of wall ties, failing to meet the demands of modern rapid construction for convenient connections. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a scaffolding tool-type wall tie that is resistant to high wind pressure, aiming to improve the problem that fixing scaffolding to the wall by wire rope alone is cumbersome and inconvenient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a scaffolding tool-type wall tie resistant to high wind pressure, comprising a universal connector buckle, a connecting rod fixedly connected to one side of the universal connector buckle, a connecting pin fixedly connected to one end of the connecting rod, and a connecting component provided inside the connecting pin;

[0007] The connecting component includes a limiting post, both ends of which are fixedly connected to the inside of a connecting pin. The outer wall of the limiting post is slidably connected to symmetrically arranged locking blocks. A first spring is sleeved on the outer wall of the limiting post, both ends of which are fixedly connected between the locking blocks. A reset component is provided between the locking blocks.

[0008] As a further description of the above technical solution:

[0009] The reset assembly includes a second spring, which is disposed between the locking blocks. Both ends of the second spring are fixedly connected between the locking blocks, and a limit component is provided inside the second spring.

[0010] As a further description of the above technical solution:

[0011] The limiting component includes a telescopic rod, which is disposed inside the second spring, and both ends of the telescopic rod are fixedly connected between the locking blocks.

[0012] As a further description of the above technical solution:

[0013] The connecting pin is internally fixedly connected to a second limiting post, and one end of the second limiting post is fixedly connected to a second limiting plate.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the second limiting post is slidably connected to the first limiting plate, and both sides of the first limiting plate are fixedly connected to connecting rods.

[0016] As a further description of the above technical solution:

[0017] The connecting rod is slidably connected inside the connecting pin, and a pull plate is fixedly connected to one end of the connecting rod.

[0018] As a further description of the above technical solution:

[0019] The other end of the connecting rod is fixedly connected to a disassembly ring, which is slidably connected to the outer wall of the connecting pin.

[0020] As a further description of the above technical solution:

[0021] A third spring is fitted on the outer wall of the second limiting post. One end of the third spring is fixedly connected to the inside of the connecting pin, and the other end of the third spring is fixedly connected to one side of the first limiting plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the universal connector is first inserted into the pre-reserved installation hole in the wall through the connecting pin. Then, the locking block in the connecting pin is embedded in the hole, which achieves the effect of facilitating the installation of the wall tie. This solves the problem that fixing the scaffold and the wall with only wire rope is cumbersome and inconvenient, and improves the connection convenience of the wall tie.

[0024] 2. In this utility model, the pull plate drives the connecting rod to slide the disassembly ring on the outer wall of the connecting pin. Then, the disassembly ring drives the locking block to retract into the connecting pin. After the connecting pin is disassembled from the wall, the connecting rod passes through the third spring on one side of the limiting plate. The tension of the third spring pushes the limiting plate to reset the connecting rod, achieving the effect of easy disassembly. This solves the problem that the wall tie cannot be reused after disassembly, and improves the practicality of the wall tie. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a high wind pressure resistant scaffolding tool-type wall tie, including a universal connector 1, which connects to the uprights or horizontal bars of the scaffolding and allows for a certain angle of rotation to adapt to changes in the installation angle on site. A connecting rod 2 is fixedly connected to one side of the universal connector 1, which serves as the main body of the wall tie, transmitting tension and pressure to ensure the distance between the scaffolding and the wall. A connecting pin 3 is fixedly connected to one end of the connecting rod 2, which serves as the execution end for insertion into a pre-drilled hole in the wall and is a key part for achieving connection with the building. A connecting component is provided inside the connecting pin 3; its function is to achieve an automatic locking function after the connecting pin is inserted into the wall hole.

[0033] The connecting assembly includes a limiting post 4, which serves as a guide shaft for the internal moving parts, ensuring stable radial movement of the locking blocks. Both ends of the limiting post 4 are fixedly connected to the connecting pin 3, providing robust support for the guide shaft and ensuring the stability of the internal mechanism. Symmetrically arranged locking blocks 5 are slidably connected to the outer wall of the limiting post 4, acting as locking teeth that extend from the connecting pin body and engage with the inner wall of the pre-drilled hole in the wall. A first spring 6 is sleeved on the outer wall of the limiting post 4, acting as a drive spring to provide continuous elastic force for the extension of the locking blocks. Both ends of the first spring 6 are fixedly connected between the locking blocks 5, automatically pushing the two locking blocks outwards through its compressed rebound force for quick locking. A reset assembly is provided between the locking blocks 5, providing a mechanism to retract the locking blocks when the wall connection needs to be disassembled. The reset assembly includes a first... The second spring 8 assists the locking blocks in retracting inward under external force. Located between the locking blocks 5, the second spring 8 works in conjunction with the first spring to form a complete spring system. Both ends of the second spring 8 are fixedly connected between the locking blocks 5. Its function, through its tensile properties, pulls the two locking blocks back towards the center during unlocking, disengaging them from the wall. The second spring 8 contains a limit component to precisely control the movement of the locking blocks. This limit component includes a telescopic rod 7, which acts as a physical limit device to prevent the locking blocks from disengaging. The telescopic rod 7, located inside the second spring 8, achieves a compact structural layout, saving internal space. Both ends of the telescopic rod 7 are fixedly connected between the locking blocks 5, limiting the maximum outward extension distance of the two locking blocks, preventing excessive pushing by the first spring and ensuring the reliability of the connection.

[0034] Reference Figure 4The connecting pin 3 is internally fixedly connected to a limiting post 9, which serves as an internal guide for the manual disassembly mechanism, ensuring the stability of its reciprocating motion. One end of the limiting post 9 is fixedly connected to a limiting plate 15, which acts as a reset limiting block for the disassembly mechanism, preventing excessive movement under spring pressure. The outer wall of the limiting post 9 is slidably connected to a limiting plate 10, which acts as a sliding drive component for the disassembly mechanism; its movement drives the entire disassembly linkage system. Both sides of the limiting plate 10 are fixedly connected to connecting rods 11, which act as force transmission components, transferring the displacement of the sliding drive component to the external disassembly ring. The connecting rods 11 are slidably connected inside the connecting pin 3, passing through the side wall of the connecting pin to achieve the mechanical transmission from internal operation to external execution. One end of the connecting rod 11 is fixedly connected to a pull plate 13, which serves as a point of leverage for manual operation, providing support for the user. Pulling initiates the disassembly procedure. The other end of the connecting rod 11 is fixedly connected to a disassembly ring 14, which serves as the final actuator to push the locking block. The disassembly ring 14 is slidably connected to the outer wall of the connecting pin 3. When pulled, its annular inner wall will squeeze the exposed block 5, forcing it to retract into the connecting pin 3, thereby unlocking. The outer wall of the limiting post 2 9 is fitted with a third spring 12, which serves as the reset spring of the disassembly mechanism, providing the power for automatic reset. One end of the third spring 12 is fixedly connected to the inside of the connecting pin 3, providing a fixed support point for the reset spring. The other end of the third spring 12 is fixedly connected to one side of the limiting plate 10, applying the spring force to the sliding drive component of the disassembly mechanism. When the user releases the pull plate 13, the spring will automatically push the entire disassembly mechanism back to its original position, preparing for the next use.

[0035] Working principle: When using this high wind pressure resistant scaffolding tool wall tie, when installing the universal connector 1, the universal connector 1 is inserted into the pre-reserved installation hole in the wall through the connecting pin 3. Then, the locking block 5 in the connecting pin 3 is embedded in the hole. The locking block 5 is limited in the connecting pin 3 by the limiting post 4, and is supported by the tension of the first spring 6 and the second spring 8, so that the locking block 5 can be stably fitted in the hole, achieving the effect of facilitating the installation of the wall tie.

[0036] When it is necessary to disassemble the connecting pin 3, the connecting rod 11 is driven by the pull plate 13 to slide the disassembly ring 14 on the outer wall of the connecting pin 3. Then the disassembly ring 14 drives the locking block 5 to retract into the connecting pin 3. After the connecting pin 3 is disassembled from the wall, the connecting rod 11 is pushed by the third spring 12 on one side of the limiting plate 10. The tension of the third spring 12 pushes the limiting plate 10 to reset the connecting rod 11. Then the connecting rod 11 drives the disassembly ring 14 to reset, thus achieving the effect of easy disassembly.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
