Description

Technical Field

[0001] This utility model relates to the field of construction safety technology, specifically to a fall arrest net for construction safety management. Background Technology

[0002] In the construction industry, working at heights and edge protection are crucial for ensuring the safety of construction workers. Traditional fall arrest netting devices are typically woven from a single material (such as steel wire rope or nylon netting) and connected to the building structure via hooks or fixed supports.

[0003] However, traditional fall arrest nets are mostly single-layer mesh structures, lacking cushioning design. When in direct contact with falling objects, they are prone to tearing or breaking due to excessive local stress. For example, nylon nets or wire meshes commonly used in existing technologies are prone to deformation or damage when subjected to large impacts. Furthermore, due to different application ranges, the size of the net needs to be adjusted in a timely manner. Existing nets are prone to local collapse after splicing due to loose connections or uneven tension. This necessitates a new type of fall arrest net for construction safety management. Utility Model Content

[0004] The technical problem this invention aims to solve is that the safety is not high and the applicability is poor. This invention provides a new type of fall protection net for construction safety management.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a fall-prevention net for construction safety management, including a fall-prevention net body, hook components and an assembly mechanism;

[0006] The main body of the fall arresting net consists of a frame, a main net body, and an edge buffer strip; after the edge buffer strip is installed inside the frame, the main net body is installed on the edge buffer strip.

[0007] The fall arresting net consists of multiple main bodies. Adjacent fall arresting net bodies are spliced ​​together horizontally or vertically through an assembly mechanism, and then fixed in place by hook components.

[0008] As an improvement, an edge buffer strip is set around the inner wall of the main mesh, which is a ring-shaped rubber strip and embedded with high-polymer energy-absorbing fibers.

[0009] As an improvement, the main mesh is a double-layer composite mesh, including a high-strength nylon mesh and a UV-resistant polyester fiber mesh. The UV-resistant polyester fiber mesh is placed on the outside, and the inner layer is a high-strength nylon mesh. There is a pair of main meshes, and the two main meshes are connected to the edge buffer strips above and below.

[0010] As an improvement, the frame surface is covered with an elastic rubber layer to prevent the rigid structure from directly contacting the human body or objects.

[0011] As an improvement, the assembly mechanism includes connectors and connecting blocks;

[0012] The connector includes two connecting plates. The connector is fixedly installed on the outer wall of one side of the frame, and multiple connectors are provided. The outer wall of the other side of the frame is provided with a connecting block that cooperates with the connector. After the main bodies of the fall arrest net are arranged in sequence, the connecting block of one fall arrest net body extends to the two connecting plates of the connector of the other fall arrest net body. After the bolts pass through the pre-set through holes on the connecting plates and connecting blocks, they are tightened with nuts.

[0013] As an improvement, an auxiliary support mechanism is also included; the auxiliary support mechanism includes an auxiliary support rod;

[0014] The auxiliary support rods are ordinary support rods or elastic ropes, etc. A pair of auxiliary support rods are provided. After the two auxiliary support rods are placed in a cross shape through the assembly, their two ends are fixed to the diagonal lines of the main net body. Automatic tensioning is achieved through prestressing design to provide auxiliary support for the bottom of the net body.

[0015] As an improvement, the assembly includes a first mounting sleeve and a second mounting sleeve, with the first mounting sleeve fixed above the second mounting sleeve, and the first and second mounting sleeves arranged in an X-shape.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. The main mesh adopts a double-layer composite structure, which effectively disperses impact force and extends service life;

[0018] 2. The edge buffer zone uses a ring-shaped rubber belt + high-polymer energy-absorbing fiber, which absorbs the kinetic energy of falling objects through elastic deformation, reduces the risk of the net being torn, and solves the problem of weak impact resistance and easy damage of traditional single-layer nets;

[0019] 3. The modular splicing design of connectors and connecting blocks allows for free combination in the horizontal and vertical directions, adapting to different span requirements, expanding the scope of use, and improving the stability of use;

[0020] 4. The auxiliary support rods and X-shaped cross components are used to achieve automatic tensioning through prestressing design, providing auxiliary support to the bottom of the net and improving safety during use. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Example 1

[0031] Combined with appendix Figure 1-4 As shown, the construction safety management of the building includes a fall arrest net, a hook assembly 1, and an assembly mechanism; the fall arrest net includes a frame 2, a main net body 4, and an edge buffer strip 3; the surface of the frame 2 is covered with an elastic rubber layer 5 to reduce direct contact between the rigid frame 2 and the human body or objects, thereby reducing the risk of secondary injury.

[0032] After the edge buffer strip 3 is installed on the inner edge of the frame 2, the main mesh body 4 is installed on the edge buffer strip 3. The edge buffer strip 3 is a ring-shaped rubber strip that surrounds the inner wall of the main mesh body 4 and is embedded with high-polymer energy-absorbing fibers. It absorbs the impact energy of falling through elastic deformation. The main mesh body 4 is a double-layer composite mesh, including a high-strength nylon mesh and a UV-resistant polyester fiber mesh. The UV-resistant polyester fiber mesh is set on the outside and the inner layer is a high-strength nylon mesh. There is a pair of main mesh bodies 4, and the two main mesh bodies 4 are connected to the edge buffer strip 3 at the top and bottom respectively.

[0033] The fall arresting net has multiple main bodies. Adjacent fall arresting net bodies are spliced ​​horizontally or vertically through an assembly mechanism, and then hung and fixed in the use position by hook assembly 1. The assembly mechanism includes connectors and connecting blocks 7. The connectors include two connecting plates 6. The connectors are fixedly set on the outer wall of one side of the frame 2, and multiple connectors are set. The outer wall of the other side of the frame 2 is provided with connecting blocks 7 that cooperate with the connectors. After the fall arresting net bodies are arranged in sequence, the connecting block 7 of one fall arresting net body extends to the two connecting plates 6 of the connector of the other fall arresting net body. After the bolts pass through the pre-set through holes on the connecting plates 6 and connecting blocks 7, they are tightened with nuts.

[0034] When adjacent fall arresting net bodies are arranged in sequence, the connecting block 7 of one frame 2 extends to the two connecting plates 6 of the connecting parts of the adjacent frame 2. After the bolts pass through the through holes, they are tightened with nuts to achieve horizontal or vertical splicing to adapt to different span requirements.

[0035] Example 2

[0036] Based on Example 1, combined with Appendix Figure 5-6 As shown, it also includes an auxiliary support mechanism; the auxiliary support mechanism includes an auxiliary support rod 8; the auxiliary support rod 8 is an elastic rope or an ordinary support rod, and a pair of auxiliary support rods 8 are provided. After the two auxiliary support rods 8 are placed in a cross shape through the assembly, their two ends are fixed to the diagonal lines of the main net body 4 respectively. The prestressed tension design ensures that the net body remains flat under strong winds or dynamic impacts.

[0037] The assembly includes a first mounting sleeve 9 and a second mounting sleeve 10. The first mounting sleeve 9 is fixed above the second mounting sleeve 10, and the first mounting sleeve 9 and the second mounting sleeve 10 are arranged in an X-shape.

[0038] In the specific implementation of this utility model, if it is necessary to cover a large area, multiple fall protection net bodies are arranged in sequence, and connectors are used to cooperate with connecting blocks 7. After bolts are passed through the through holes, they are locked to achieve horizontal or vertical splicing and form continuous protection. After splicing, check whether the connection is tight and without obvious gaps.

[0039] Based on the conditions of the construction site, select scaffold crossbars, steel beams, pre-embedded anchor points or wall structures as fixed hanging points to ensure that the load-bearing capacity of the hanging points meets the requirements. After hanging the hook assembly 1 on the selected hanging point, tighten the locking mechanism to ensure a stable connection and prevent slippage.

[0040] After installation, the two main net bodies 4 work together to prevent falls during use. The edge buffer strip 3 cushions the fall, and the prestress function of the auxiliary support rod 8 ensures that the net body is taut and prevents sagging.

[0041] Regularly clean the mesh surface to remove dust and debris, check the edge buffer strip 3 for aging, and replace damaged parts if necessary;

[0042] After use, first loosen the hook locking mechanism, remove the netting unit one by one, remove the connecting bolts between adjacent netting units, separate the modules, and intact modules can be used directly for the next project to improve resource utilization. For slightly damaged netting, only local components (such as main netting 4 or buffer strip) need to be replaced, without replacing the whole set, saving costs.

[0043] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
