Description

Technical Field

[0001] This utility model relates to the field of construction safety devices, and in particular to a scaffolding anti-fall component for construction and installation. Background Technology

[0002] Scaffolding fall arrestor systems are protective facilities used during construction to ensure the safety of personnel and materials. Their main function is to prevent workers or materials from falling during high-altitude operations. Scaffolding fall arrestor systems consist of components such as fixing devices, support structures, safety hooks and rings, warning signs, cushioning devices, and detection devices. The fixing devices secure the fall arrestor net to the scaffolding. The support structure ensures the fall arrestor net maintains tension during use, preventing deformation or detachment. The safety hooks and rings allow for easy hanging of the fall arrestor net on the scaffolding and adjustment of its height and tension. Warning signs raise worker safety awareness. The cushioning device reduces impact and minimizes injury in the event of a fall. The detection device monitors the system's stability in real time, ensuring the long-term effectiveness of the fall arrestor system.

[0003] Existing scaffolding fall protection components still have some problems in use. For example, traditional scaffolding fall protection systems generally adopt a combination of fixed guardrails and top safety nets. However, fixed guardrails require on-site welding or bolting, which is time-consuming and labor-intensive to install and cannot be quickly adjusted in height. Although traditional safety nets can intercept falling objects, they lack an effective cushioning structure, and falling objects are prone to bounce and splash after impact, posing a secondary threat to personnel and equipment below. Existing fall protection components are mostly single-function designs, either only for personnel fall protection or only for intercepting falling objects, and cannot achieve comprehensive protection, which can easily create safety hazards.

[0004] To address these issues, we provide a scaffolding fall arrestor for building construction and installation. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of single form of fall protection and inconvenience of assembly. To this end, we propose a fall protection component for scaffolding in building construction and installation.

[0006] To achieve the above objectives, this application adopts the following technical solution: a fall protection component for scaffolding in building construction and installation, including a footboard, with uprights provided around the top of the footboard, and a guardrail movably connected to the surface of the uprights; an assembly component is provided on the surface of the guardrail, the assembly component including compression springs fixedly connected to both sides of the inner cavity of the guardrail, a plug rod fixedly connected to one end of the compression spring, a push-pull block fixedly connected to one side of the surface of the plug rod, and an installation ring fixedly connected to one side of the surface of the upright, the assembly component being used to assemble the fall protection structure; a protective component is provided in the inner cavity of the upright, the protective component including an adjusting rod slidably connected to the inner cavity of the upright, a support block fixedly connected to one end of the adjusting rod, and a fall protection net fixedly connected to one side of the support block, the protective component being used to prevent falling objects from heights from causing injury to workers.

[0007] Preferably, the foot pedal has connection holes around its top perimeter, one end of the upright is slidably connected to the inner cavity of the connection hole, and the inner cavity of the mounting ring is threaded with a bolt, one end of which extends into the foot pedal.

[0008] Preferably, the inner cavity of the upright has an adjustment hole, the inner cavity of the adjustment hole extends into the interior of the adjustment rod, and the inner cavity of the adjustment hole is threadedly connected to a limit pin.

[0009] Preferably, an insertion hole is provided on one side of the inner cavity of the upright, and one end of the insertion rod is slidably connected to the inner cavity of the insertion hole.

[0010] Preferably, a groove is provided on one side of the guardrail, and the push-pull block extends to the outside of the guardrail through the inner cavity of the groove, and the inner cavity of the groove is slidably connected to the surface of the push-pull block.

[0012] Preferably, the fall protection net is rectangular and planar, and is composed of an impact-resistant layer, an elastic buffer layer, and a damping layer.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model achieves rapid assembly and disassembly and height adjustment of the guardrail through the sliding connection design of the foot pedal and the upright, in conjunction with the compression spring, insert rod and mounting ring in the assembly components. It eliminates the need for welding or complex fastening, significantly improving installation efficiency. The guardrail and the upright are stably locked through the cooperation of the insert rod and the insertion hole. At the same time, the design of the push-pull block facilitates manual operation and ensures that the fall protection structure remains firm during construction, effectively preventing people from falling. In addition, the support plate and guardrail at the top of the guardrail further enhance the stability of the overall structure, making the protection system more reliable and suitable for various complex construction environments.

[0015] 2. This utility model utilizes an adjustable-height fall protection net in its protective components. The net is flexibly raised and lowered via an adjusting rod and limiting pins to adapt to different work levels. The net employs a composite structure design consisting of an impact-resistant layer, an elastic buffer layer, and a damping layer. This effectively absorbs the impact energy of falling objects, reduces the risk of rebound, and prevents secondary injuries to personnel or equipment below. Simultaneously, the net's rectangular planar structure ensures maximum coverage, and combined with the stable support of the uprights, it forms all-around protection, significantly improving the safety of high-altitude operations. This design not only meets the fall protection requirements of construction work but also considers convenience and reliability, possessing high practical value. Attached Figure Description

[0024] Example 1

[0025] Please see Figures 1-5 This utility model relates to a scaffolding fall prevention component for construction and installation, comprising a footboard 1, which is a structure installed on the scaffolding for support and to facilitate worker movement. Uprights 2 are provided around the top of the footboard 1, and the uprights 2 are used to install guardrails 3 and adjusting rods 8. Guardrails 3 are movably connected to the surface of the uprights 2, and the height of the guardrails 3 is sufficient to protect workers from falls. An assembly component is provided on the surface of the guardrails 3, including compression springs 4 fixedly connected to both sides of the inner cavity of the guardrails 3. Compression holes are provided on both sides of the inner cavity of the guardrails 3. One end of the compression spring 4 is fixedly connected to one side of the inner cavity of the compression hole, and one end of the compression hole extends to the outside of the guardrails 3 to allow a rod 5 to extend into the insertion hole 15 of another upright 2. A push-pull block 6 is fixedly connected to one end of the compression spring 4 and to one side of the surface of the rod 5. During assembly or disassembly, the rod 5 is pulled or pushed. Block 6 can separate the insertion rod 5 from the insertion hole 15 of another insertion rod 5, thereby connecting or removing one side of the guardrail 3 to another upright 2. This method facilitates workers getting on and off the foot pedal 1 and the mounting ring 7 fixedly connected to one side of the surface of the upright 2. The bolt 12 inside the mounting ring 7 can fix the upright 2 to the inside of the foot pedal 1. The assembly component is used to assemble the fall protection structure. The inner cavity of the upright 2 is provided with a protective component, which includes an adjusting rod 8 slidably connected to the inner cavity of the upright 2. The surface of the adjusting rod 8 slides with the inner cavity of the upright 2, which can adjust the height of the fall protection net 10 to avoid the bottom of the fall protection net 10 being too close to the worker's head, causing injury to the worker from falling objects. A support block 9 is fixedly connected to one end of the adjusting rod 8, and the fall protection net 10 is fixedly connected to one side of the support block 9. The protective component is used to prevent injury to workers from falling objects from heights.

[0026] Example 2

[0027] Please see Figures 1-5Based on Embodiment 1, the foot pedal 1 has connecting holes 11 around its top perimeter. One end of the upright 2 is slidably connected to the inner cavity of the connecting hole 11. The inner cavity of the mounting ring 7 is threaded with bolts 12, and three bolts 12 are threaded into the inner cavity of the mounting ring 7. One end of each bolt 12 is screwed into a slot at the top of the foot pedal 1 to complete the installation of the upright 2. One end of each bolt 12 extends into the interior of the foot pedal 1. The inner cavity of the upright 2 has an adjustment hole 13, which allows the adjustment rod 8 to move to different heights. A limiting pin 14 can fix the adjustment rod 8. The inner cavity of the adjustment hole 13 extends into the interior of the adjustment rod 8, and a limiting pin 14 is threaded into the inner cavity of the adjustment hole 13. One side of the inner cavity of the upright 2 has an insertion hole 15. Since there are four uprights 2 on the top of the foot pedal 1, each upright 2 has an insertion hole 15 inside to facilitate the circular assembly of the four guardrails 3. One end of the insertion rod 5 is slidably connected to the inner cavity of the insertion hole 15. A sliding groove 16 is provided on one side of the guardrail 3, which allows the push-pull block 6 to move laterally. One side of the push-pull block 6 extends to the outside of the guardrail 3 through the inner cavity of the sliding groove 16. The inner cavity of the sliding groove 16 is slidably connected to the surface of the push-pull block 6. Support plates 17 are fixedly connected to both sides of the top of the guardrail 3, and guard rods 18 are fixedly connected to both sides of the support plates 17. A certain gap is left between the two guard rods 18 to facilitate the work of the staff and to facilitate the installation of external protective cables on their surface. The fall arrest net 10 is rectangular and flat. The fall arrest net 10 is composed of an impact-resistant layer, an elastic buffer layer, and a damping layer. The impact layer, elastic buffer layer, and damping layer are respectively a high-strength nylon mesh, a middle elastic silicone pad, and an inner damping cloth. The fall arrest net 10 composed of these three materials can buffer falling objects and prevent falling objects from having a high secondary rebound. It can protect the staff on the top of the footboard 1 and the personnel passing under the scaffolding.

[0028] Working principle: First, the construction worker inserts the bottom end of the upright 2 into the connecting hole 11 at the top of the foot pedal 1, and tightens it using the bolt 12 inside the mounting ring 7, completing the rapid installation of the upright 2. Then, the guardrail 3 is connected to the adjacent upright 2 via the assembly components—pressing the push-pull block 6 causes the insertion rod 5 to compress the spring 4. After aligning the insertion rod 5 with the insertion hole 15 on the side of the upright 2, the push-pull block 6 is released, and the spring rebounds, causing the insertion rod 5 to automatically lock into the insertion hole 15, forming a ring-shaped protective structure. The support plate 17 and guardrail 18 at the top of the guardrail 3 further reinforce the overall stability. When the height of the fall protection net 10 needs to be adjusted, the sliding adjustment rod 8 is moved to the target position. The limit pin 14 is screwed into the adjustment hole 13 for fixation. The support block 9 drives the fall protection net 10 to rise and fall synchronously. The three-layer composite structure of the fall protection net 10 absorbs energy step by step when the object falls. The high-strength nylon net disperses the initial impact force, the elastic silicone pad slows down the kinetic energy through deformation, and the damping cloth finally eliminates the residual energy and prevents rebound. Throughout the process, the slide 16 ensures that the push-pull block 6 moves smoothly, and the quick-release design of the guardrail 3 facilitates personnel to enter and exit the work surface. This component achieves triple protection against falls, falling objects, and rebound through the synergistic effect of mechanical linkage and material properties. At the same time, the modular structure reduces the installation time of a single layer, greatly improving construction efficiency and safety.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
