Description

Technical Field

[0001] The utility model belongs to the technical field of safe construction of building formwork supporting scaffolding systems, and relates to a suspension device for a safety lock buckle at the top of a formwork system. Background Art

[0002] During the erection process, the risk of scaffolding increases with each floor, requiring workers to work at height. This process requires constant movement back and forth across the formwork, but operators lack access to safety belts or ropes attached to the formwork support system, resulting in inadequate safety measures. This can easily lead to falls due to missed steps or insecure formwork, making it impossible to fully accommodate various on-site work environments. Utility Model Content

[0003] Aiming at the problem that the safety lock buckle is not firmly and flexibly suspended, the utility model provides a suspension device for the safety lock buckle at the top of the formwork system.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A suspension device for a safety lock on the top of a formwork system comprises a steel pipe, a closed end cover welded to the upper end of the steel pipe, a through hole formed on the closed end cover, a No. 2 nut fixedly arranged at the lower end of the steel pipe, a screw rod provided in the steel pipe, the lower end of the screw rod being threadedly connected to the No. 2 nut, and a safety collar fixedly connected to the upper end of the screw rod passing through the through hole.

[0006] Furthermore, the lower end of the steel pipe is configured to be tapered so that the steel pipe can be more conveniently placed inside the mold frame.

[0007] Furthermore, a limiting ring is provided at the upper middle portion of the outer side of the steel pipe to prevent the steel pipe from sliding into the interior of the formwork.

[0008] Furthermore, a No. 1 nut is fixedly arranged in the through hole, and the upper part of the screw rod is threadedly connected to the No. 1 nut.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] 1. The lower end of the steel pipe of the utility model adopts a tapered design, which is convenient for disassembly and assembly, and improves the efficiency of construction.

[0011] 2. The utility model adopts the design of limit ring to ensure that the steel pipe will not slide into the inside of the formwork when working in a vertical state, thus ensuring the basic safety needs of the staff.

[0012] 3. Both ends of the screw rod of the utility model are fixed with nuts, which improves the overall rigidity and strength of the safety collar, and at the same time realizes the 360° free rotation of the screw rod in the steel pipe, ensuring the safety of construction and meeting various on-site working environments to the greatest extent.

[0013] 4. The utility model has the advantages of simple structure, low manufacturing cost, easy to carry and simple operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to further illustrate the technical solution of the present invention, the present invention will be further described below through embodiments.

[0019] like Figure 1-Figure 3 As shown, a suspension device for the top safety lock of the formwork system is characterized in that it includes a steel pipe 1, a closed end cap 2 is welded to the upper end of the steel pipe 1, a through hole is opened on the closed end cap 2, a No. 2 nut 7 is fixedly provided at the lower end of the steel pipe 1, a screw rod 3 is provided in the steel pipe 1, the lower end of the screw rod 3 is threadedly connected to the No. 2 nut 7, the upper end of the screw rod 3 is fixedly connected to the safety collar 4 through the through hole, and the lower end of the steel pipe 1 is set to be conical. By adopting the conical design of the lower end, the suspension device is easy to carry. The operation is simple, so that the steel pipe 1 can be placed into the interior of the formwork more conveniently. A limit ring 5 is provided at the upper middle part of the outer side of the steel pipe 1 to prevent the steel pipe 1 from slipping into the interior of the formwork. A No. 1 nut 6 is fixed in the through hole, and the upper part of the screw rod 3 is threadedly connected with the No. 1 nut 6. There are No. 1 nuts 6 at both ends of the screw rod 3, and No. 2 nuts 7 are fixed, which improves the overall rigidity and strength of the safety ring 4, and at the same time realizes the 360° free rotation of the screw rod 3 in the steel pipe 1, ensuring the safety of construction and meeting various on-site working environments to the greatest extent.
