In the construction field, especially during the facade construction of high-rise buildings, working at heights is very common. To ensure the safety of workers, reliable safety harness suspension devices are necessary. Traditional suspension methods typically include the use of scaffolding, temporary fixing devices, or embedded parts. These methods suffer from problems such as complex installation, high cost, and poor flexibility. This not only increases construction costs and difficulty but may also cause some damage to the building's structure. Summary of the Invention

[0011] Furthermore, the outer diameter of the first ring is smaller than the outer diameter of the second ring.

[0012] Furthermore, the end of the threaded hole is provided with a second protrusion.

[0013] Furthermore, the anti-slip structure includes several arcuate protrusions disposed on the inner wall of the ring.

[0014] The above-mentioned technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: Tie bolts are required during facade construction; therefore, the suspension device of this application can be directly used during facade construction, with the ring at the end of the pole serving as the stress point for the safety belt suspension. No additional suspension stress point needs to be added later, greatly improving construction efficiency and safety. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0020] This specification provides an example of a safety belt suspension device for exterior facade construction. Please refer to [link / reference]. Figure 1 As shown, it includes a tie rod 1, which includes a rod body 11, a threaded end 12, and a suspension end;

[0021] The suspension end includes a ring 13, which is connected to one end of the rod 11, and a threaded end 12 is located at the other end of the rod 11. The inner wall of the ring 13 has an anti-slip structure. An M12 tie rod is used, which has sufficient strength and rigidity to withstand the tension generated when the seatbelt is suspended. Two washers are spaced apart on the rod, and a matching nut is provided at the threaded end. The nut is used to adjust the length and tightness of the tie rod, ensuring its stability within the wall. The washers are located at both ends of the tie rod to distribute the tension and prevent the tie rod from being pulled out of the wall. The ring is circular, with a diameter slightly larger than the hook size, so that the hook can be easily attached to the ring. The ring and the rod are connected by welding or integral molding to ensure the strength and stability of the connection. For example: the end of the ring in the M12 tie rod 1 is welded to the horizontal section of the rod on one side, and the upper ring is perpendicular to the lower rod body; the ring 1 in the upper M12 tie rod has an inner diameter of Φ100mm, is made of Ф12HPB300 steel bar cold-bent, and has a roundness error of ≤2mm; the washer 2 is a 50mm square steel washer with a thickness of 5mm and is made of Q235 steel; the nut 3 is a nut that matches the tie rod, and the double nut installation ensures that the rod body is tightly attached to the wall and is stable.

[0022] In a further preferred embodiment, a first protrusion 14 is provided at the connection between the ring 13 and the rod 11 to abut against the pad and distribute the force. The anti-slip structure includes several arc-shaped protrusions provided on the inner wall of the ring. This reduces the slippage of the seat belt hook.

[0023] Since tie bolts are required during facade construction, this embodiment allows the suspension device of this application to be used directly during facade construction, with the ring at the end of the pole serving as the stress point for the safety belt suspension. This eliminates the need for additional suspension stress points during later construction, greatly improving construction efficiency and safety.

[0024] In another possible implementation, please refer to Figure 2 As shown, the ring 13 is a figure-eight structure composed of two rings, including a first ring 131 and a second ring 132. A threaded hole 133 is provided between the two rings, and the rod body 11 has an external thread 111 that matches the threaded hole 133. Depending on the thickness of the wall, both ends of the rod body can be adjusted via the threads to adapt to the wall thickness. Furthermore, when the safety belt hook is attached to one of the rings, this ring can be continuously tightened with the rod body under force, further providing stability.

[0025] Preferably, the outer diameter of the first ring is smaller than the outer diameter of the second ring. This improves distinguishability during use. A second protrusion is provided at the end of the threaded hole to abut against the gasket.

[0026] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0027] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
