[0018] 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.
[0019] See below. Figures 1-5 This invention provides a detailed description of the safety protection device for dismantling external scaffolding.
[0020] This utility model discloses a safety protection device for dismantling scaffolding, comprising multiple climbing hangers 1 horizontally spaced and installed on the roof concrete structure, and nylon ropes 2 fixed to the climbing hangers 1 by first rope clips 3. The nylon ropes 2 are vertically arranged and their bottoms are fixed and taut to the ground. Self-locking devices 6 are installed on the surface of the nylon ropes 2, and horizontally arranged steel wire ropes 7 are threaded through the holes of the self-locking devices 6. The two ends of the steel wire ropes 7 are fixed to the self-locking devices 6 by second rope clips 8. The multiple nylon ropes 2 form a longitudinal safety line, and the multiple steel wire ropes 7 form a transverse safety line. The nylon ropes 2 and steel wire ropes 7 intertwine to form a closed-loop interlocking structure. The number of climbing hangers 1 is specified, and the number of nylon ropes 2 corresponds to the number of climbing hangers 1.
[0021] The climbing frame 1 has an expansion bolt 4 inside, with a nut 5 threaded to one end. A self-locking device 6 is installed on the surface of the nylon rope 2, and a steel wire rope 7 is installed through the hole in the self-locking device 6. Second rope clips 8 are installed at both ends of the steel wire rope 7, securing it to the outermost self-locking device 6. The climbing frame 1 is installed on the roof concrete structure using the expansion bolt 4 and nut 5. The upper end of the nylon rope 2 is passed through the hole in the climbing frame 1 and knotted for fixation. The knot of the nylon rope 2 is secured with the first rope clip 3 to prevent loosening. The bottom of the nylon rope 2 is fixed and taut to the ground and can be tied to the frame at the bottom of the landing frame. If there is no landing frame, eye bolts can be used for fixing and tying on the ground.
[0022] The spacing of the nylon ropes 2 can be between 8 and 15 meters, adjusted according to the building structure, to form a longitudinal safety line. Then, self-locking devices 6 are installed on the nylon ropes 2, and steel wire ropes 7 are threaded through the holes in the self-locking devices 6. This process is repeated on several nylon ropes 2. Both ends of the steel wire ropes 7 are secured with second rope clips 8 to form a transverse safety line and a closed-loop interlocking structure, ensuring the overall stability of the scaffolding dismantling process and improving safety during use. All components are existing, low-cost pre-made products. When dismantling scaffolding for multiple individual buildings, the entire system, except for the expansion bolts 4, can be reused, improving practicality.
[0023] The climbing harness 1 is made of 304 stainless steel. The climbing harness 1 has a through hole for the nylon rope 2 to pass through. The inner wall of the through hole is smoothly designed so as not to cut the nylon rope 2 and to extend the service life of the nylon rope 2.
[0024] The diameter of nylon rope 2 is ≥16mm, which gives it higher tensile strength and abrasion resistance, enabling it to withstand greater weight and tension, and improving safety during use.
[0025] The number of self-locking devices 6 is set to a certain number. After the upper scaffolding is dismantled, the self-locking devices 6 on the nylon rope 2 are moved down, allowing the wire rope 7 to move downwards, facilitating the dismantling of the lower scaffolding. The number of self-locking devices 6 can be adjusted according to the dismantling progress.
[0026] The surface of the wire rope 7 is covered with a protective sleeve, on which a lifeline is attached. The lifeline can be attached to the protective sleeve for use, solving the problems of difficult installation, frequent displacement, and weak protection. The protective sleeve reduces friction between the lifeline's clips and the wire rope, extending its service life.
[0027] The protective sleeve is made by cutting rubber hoses and serves to protect the wire rope 7, extending its service life. The protective sleeve has good flexibility and abrasion resistance, allowing it to bend along with the wire rope 7.
[0028] Below, refer to Figures 1 to 5 Based on the above description of structural features, the working principle of the safety protection device for dismantling scaffolding of this utility model will be briefly described as follows: In use, the climbing bracket 1 is installed on the roof concrete structure using expansion bolts 4 and nuts 5. The upper end of the nylon rope 2 is passed through the hole in the climbing bracket 1 and knotted for fixation. The top of the nylon rope 2 is knotted and fixed using the first rope clip 3 to prevent loosening. The bottom of the nylon rope 2 is fixed and tightened to the ground and can be tied to the bottom frame of the landing frame. If there is no landing frame, eye bolts can be used to fix and tie it on the ground. The spacing of the nylon rope 2 can be within 8 to 15 meters, which can be adjusted according to the building structure to form a longitudinal safety line.
[0029] Then, the self-locking device 6 is installed on the nylon rope 2, and the steel wire rope 7 is passed through the hole of the self-locking device 6. The above settings are repeated on several nylon ropes 2 in this manner. Both ends of the steel wire rope 7 are fixed with the second rope clip 8 to form a horizontal safety line and a closed-loop interlocking structure, which ensures the overall stability of the scaffolding dismantling process and improves the safety during use. The life rope can be hung on the steel wire rope 7, which solves the problems of difficult hanging, frequent displacement, and weak protection. All components of the overall setup are existing and low-cost finished products. When facing the dismantling of multiple single scaffoldings, the entire system can be reused except for the expansion bolt 4, which improves its practicality. After the upper scaffolding is dismantled, the self-locking device 6 on the nylon rope 2 is moved down so that the steel wire rope 7 can be moved downwards to facilitate the dismantling of the lower scaffolding. It can be adjusted according to the dismantling progress.
[0030] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of this utility model.
