Description

Technical Field

[0001] This utility model relates to the field of construction safety auxiliary equipment technology, specifically a safety suspension mechanism for high-altitude construction of buildings. Background Technology

[0002] On high-altitude scaffolding in building construction, the safety of construction workers is paramount. Therefore, safety suspension mechanisms are necessary to prevent accidental falls and protect their lives. The main function of a safety suspension mechanism is to prevent workers from falling due to slips or other unforeseen circumstances while working at heights, providing them with a safety guarantee so they can perform various operations with greater peace of mind, thereby improving work efficiency. A safety suspension mechanism typically consists of several parts, including a safety belt, connecting rings, anchor points, safety rope, and possibly cushioning devices. The safety belt is the primary protective equipment worn by construction workers. The connecting rings are used to connect the safety belt to other safety equipment, while the anchor points are the steel columns or other robust structures of the scaffolding, capable of withstanding applied forces. The safety rope connects the safety belt and the anchor points and is usually made of high-strength synthetic fibers, possessing good tensile strength and abrasion resistance.

[0003] As disclosed in the authorization announcement number CN211421903U, a safety suspension mechanism for high-altitude construction in building construction includes a sling and a fixing ring. Two sets of fixing straps are installed in the lower middle part of the sling. A connecting block is installed on the left side of the fixing ring. A first threaded hole is provided on the top right side of the fixing ring. A bolt is installed inside the first threaded hole. The insert rod on the buckle is inserted into the T-slot in the buckle groove. The stop block fixes the buckle in the T-slot. After the buckle and the groove are fixed, they form an "I" shape. One fixing strap is fixed at the worker's armpit and the other is fixed at the worker's waist, providing the worker with an effective safe working environment. However, in the process of using the above technical solution, it mainly restrains the user's armpit and waist. The sling is connected to the scaffold guardrail. In high-altitude operations, construction workers usually need to adjust various postures, including bending, stretching, and turning. At this time, the user's upper limbs feel very restricted during construction operations, especially when it is necessary to frequently raise the hand or turn around. The restriction will significantly affect the work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a safety suspension mechanism for high-altitude construction in building construction. The inner C-shaped arm, which is movably installed inside the double-layer C-shaped frame, is worn at the user's waist position through a tightening strap and a safety belt connector. At the same time, the double-layer C-shaped frame is connected to the scaffold guardrail through two nylon ropes and a safety hook, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety suspension mechanism for high-altitude construction in building construction, comprising a double-layer C-frame, an inner C-arm movably installed on the inner wall of the double-layer C-frame, tension straps installed at both ends of the inner C-arm, and a safety belt connector for connecting the opposite ends of the two tension straps. A U-shaped ring is fixed at the bottom end of the double-layer C-frame, and nylon ropes are installed on both sides of the bottom end of the U-shaped ring. A safety hook is installed at the end of the nylon rope away from the U-shaped ring.

[0006] Preferably, the double-layer C-shaped frame includes an upper frame, a lower frame, and an integrally formed connecting part between the ends of the upper and lower frames, which are disposed on the back of the inner C-shaped arm.

[0007] Preferably, two symmetrical connecting arms are integrally formed on the inner wall of the upper frame, and two symmetrical lugs are integrally formed on the back of the inner C-shaped arm. One end of the lug extends into the interior of the connecting arm, and a hinge shaft is installed on one side of the outer wall of the connecting arm. The end of the hinge shaft extends through the connecting arm and the lug to the outside.

[0008] Preferably, a knot is installed at both ends of the nylon rope, and the safety hook is connected to one of the knots.

[0009] Preferably, both ends of the U-shaped ring are fitted with connecting rings, and the connecting rings and another knot at the end of the nylon rope are interlocked.

[0010] Preferably, the length of the nylon rope is 1m to 1.5m.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This safety suspension mechanism for high-altitude construction in building construction allows the inner C-shaped arm, which is movable inside the double-layer C-shaped frame, to be worn around the user's waist via a tightening strap and a safety belt connector. It also employs a structural design where the double-layer C-shaped frame is connected to the scaffolding guardrail via two nylon ropes and a safety hook. The double-layer C-shaped frame design provides a stable support structure, and the movable installation of the inner C-shaped arm allows the safety belt to better fit the user's body and be flexibly adjusted according to the worker's movements. In the event of an accident, the tightening strap and safety belt connector can quickly dissipate the applied force. The impact force is distributed across the entire double-layer C-frame, reducing the impact on specific areas and effectively lowering the severity of falls. Secondly, the harness is worn around the user's waist; compared to the traditional shoulder strap, waist straps reduce the feeling of restriction on the upper limbs and shoulders, allowing workers greater freedom of movement and reducing discomfort caused by restraint during high-altitude operations. Finally, the double-layer C-frame is connected to the scaffolding railing via nylon rope and safety hooks, ensuring the effectiveness of the safety harness. Even during high-altitude operations, the movement range of workers is effectively controlled, preventing the risk of falls due to loss of balance. Attached Figure Description

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5 An embodiment of this utility model is provided: a safety suspension mechanism for high-altitude construction of buildings, including a double-layer C-frame 1, an inner C-arm 2 movably installed on the inner wall of the double-layer C-frame 1, a tightening strap 3 installed at both ends of the inner C-arm 2, and a safety belt connector 4 for connecting the opposite ends of the two tightening straps 3. A U-shaped ring 5 is fixed at the bottom end of the double-layer C-frame 1, and nylon ropes 6 are installed on both sides of the bottom end of the U-shaped ring 5. A safety hook 7 is installed at the end of the nylon rope 6 away from the U-shaped ring 5.

[0020] The double-layer C-frame 1 includes an upper frame 101, a lower frame 102 and an integrally formed connecting part 103 between the ends of the upper frame 101 and the lower frame 102, which are disposed on the back of the inner C-frame 2. The upper frame 101, the lower frame 102 and the connecting part 103 form a protective zone around the user's waist. The double-layer design can effectively prevent tools and materials from falling from a height and reduce the risk of injury to the user's waist.

[0021] Two symmetrical connecting arms 104 are integrally formed on the inner wall of the upper frame 101. Two symmetrical lugs 201 are integrally formed on the back of the inner C-shaped arm 2. One end of the lug 201 extends into the interior of the connecting arm 104. A hinge shaft 8 is installed on one side of the outer wall of the connecting arm 104. The end of the hinge shaft 8 passes through the connecting arm 104 and the lug 201. When the inner C-shaped arm 2 is worn on the user's waist through the tightening strap 3 and the safety belt connector 4, the inner C-shaped arm 2 rotates relative to the connecting arm 104 through the lug 201 and the hinge shaft 8 to ensure the flexibility of the user's waist and reduce the feeling of restraint on the waist, making it convenient for the staff to perform various operations.

[0022] The nylon rope 6 is 1m to 1.5m long. Both ends of the nylon rope 6 are equipped with knot buckles 601. The safety hook 7 is connected to one of the knot buckles 601. Both ends of the U-shaped ring 5 are fitted with connecting rings 501. The connecting rings 501 are connected to the other knot buckle 601 at the end of the nylon rope 6. The top of the nylon rope 6 is connected to the U-shaped ring 5 through the knot buckle 601 and the connecting ring 501. After being connected to the scaffolding guardrail with the safety hook 7, it can withstand greater weight and impact force to ensure safety.

[0023] The design of two nylon ropes (approximately 6mm each) can evenly distribute the load, reducing the risk of equipment imbalance or breakage caused by excessive force on one side, thereby improving overall safety.

[0024] In this embodiment, the user first wears the harness 3 around the waist, ensuring it fits snugly against the body. The user then adjusts the tightness of the harness 3 according to their body shape, ensuring it is neither loose nor compressing, for comfort during work. The two harnesses 3 are then connected using the safety belt connector 4, ensuring it is not loose or not fully inserted. A stable connection point is selected on the scaffolding railing, ensuring the nylon rope 6 can support the worker's weight and effectively prevent a fall. The safety hook 7 at the bottom of the nylon rope 6 is connected to the scaffolding railing, ensuring it is fully closed to prevent accidental detachment during operation. When working at height, the worker maintains balance and avoids violent movements. The movable design of the inner C-arm 2 and the double-layer C-frame 1 allows the worker to move freely within a certain range, enabling flexible operation. Upon returning to the ground, the safety belt connector 4 of the harness 3 is first released, followed by disassembling the nylon rope 6 and safety hook 7, among other components.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
