Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude operations, and particularly relates to a safety protection device for high-altitude construction of steel structures. Background Technique

[0002] Steel structure projects have received increasing attention in the market, especially in building construction and bridge construction. However, there are often significant safety risks for high-altitude operations above 2 meters with complex shapes. For high-altitude steel structure construction, horizontal channels, hanging cages, scaffolding, and aerial work platforms are usually used as safety protection. However, horizontal channels and hanging cages are only suitable for steel structures with relatively gentle structures; using scaffolding as a construction and protection platform for high-altitude operations involves a huge amount of work, high costs, and long time consumption, and there are also significant safety hazards during the erection process. Therefore, the use of safety ropes has received extensive attention;

[0003] After retrieval, in the application document with the patent application number 202321218779.5, a safety protection device for super-high-rise steel structure construction is disclosed, including a safety rope and a connection structure. One end of the safety rope is connected to a high-altitude safety suit, the connection structure is fixed on the steel structure, and the other end of the safety rope is fixed on the connection structure. The connection structure includes two connection components, a first screw rod, and a second screw rod. A hanging ring is fixedly connected to the middle of the second screw rod, the safety rope is fixedly connected to the hanging ring, both ends of the first screw rod pass through the third gear rods and movable pieces of the two connection components and are threadedly connected to the first nuts, and both ends of the second screw rod pass through the second gear rods and connection pieces of the two connection components and are threadedly connected to the second nuts. This enables the safety rope to be connected to the steel structure and move conveniently, forming a movable suspension point for high-altitude safety operation protection. Through the coordinated use of the first screw rod, second screw rod, first nut, and second nut in the connection structure, the connection structure can be conveniently assembled and disassembled with the steel structure, facilitating use;

[0004] The above application document uses a connection structure and a safety rope. However, first, its structure is numerous and complex, and it also requires cumbersome positioning at high altitudes, and its safety needs to be improved. Second, it is a top-side connection, which may affect the subsequent construction of workers standing on the steel frame, and the swaying safety rope also has a certain impact.

[0005] Therefore, we propose a safety protection device for high-altitude construction of steel structures. Content of the Utility Model
