Description

Technical Field

[0001] This utility model relates to the field of scaffolding construction technology, and in particular to a retractable interlayer flat net device. Background Technology

[0002] Various edge protection measures are the best choice to eliminate edge hazards. During the construction of the main structure, the protection between the external scaffold and the main structure is often affected due to conflicts with the construction process.

[0003] A search revealed Chinese patent CN214885743U, which discloses an adjustable, modular building safety net. The net includes a wall with a horizontal bar fixedly connected internally. A second fixing device is fixedly connected to the outer surface of the horizontal bar. A first fixing device is fixedly connected to the outer surface of the horizontal bar, located to the right of the second fixing device. A first vertical pole is fixedly connected internally to the first fixing device, and a second vertical pole is fixedly connected internally to the second fixing device. A support block is fixedly connected to the upper surface of the wall. This patent, through the design of the adjusting rod and limiter, facilitates installation and disassembly. The inclined horizontal net allows for timely clearing of falling rocks, preventing secondary injuries to falling personnel. The combination of the horizontal and vertical nets ensures that falling personnel are closer to the wall, facilitating faster and more convenient rescue.

[0004] Based on the above search and existing technology, the findings were as follows:

[0005] The aforementioned patent employs a multi-component, multi-connection-point design, which is complex and cumbersome to install. Errors may occur during installation, reducing construction efficiency and making it impossible to achieve flexible installation and removal. In addition, the development of a large number of specialized components and the cost of molds are high, thus limiting its effectiveness. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a retractable interlayer flat net device, which avoids repeated disassembly of the interlayer flat net and realizes the free retraction and deployment of the interlayer flat net.

[0007] The technical solution to achieve the purpose of this utility model is: a retractable interlayer flat net device, including a main structural layer and an outer frame, and further including a rectangular frame and connecting components:

[0008] The rectangular frame is set on the surface of the main structural layer;

[0009] The connection assembly includes multiple connectors sleeved on the outside of the frame.

[0010] Preferably, a plurality of push-button hooks are fixedly installed on the surface of the main structural layer, and a safety net is fixedly installed inside the rectangular frame, the safety net being snapped into the inside of the push-button hooks.

[0011] Preferably, one end of the rectangular frame is inserted into the interior of the connector, a pivot is provided between the connector and the rectangular frame, and multiple reflective strips are fixedly installed on the surface of the rectangular frame.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model can ensure that the interlayer protection between the external scaffolding and the main structure at the construction site can be freely retracted, avoiding the potential dangers caused by repeated disassembly and improper or untimely restoration of the interlayer flat netting, thus ensuring on-site construction safety and controllability.

[0014] Secondly, this utility model upgrades the structural materials, significantly improving the practicality, safety, and applicability of the device, giving it strong market competitiveness; the addition of press-type hooks ensures the firmness between the mesh and the structural layer, and the use of reflective strips enhances construction safety.

[0015] It solves the problems of existing patents that use a multi-component, multi-connection-point design, which makes installation complex and cumbersome, causes errors during installation, reduces construction efficiency, and cannot achieve free retraction and extension. In addition, the development of a large number of special components and the high cost of molds are also problems. Attached Figure Description

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved retractable interlayer flat netting device. The technical solution of this utility model is as follows:

[0025] Example 1

[0026] like Figure 1 As shown, a retractable interlayer protective netting device includes a main structure layer 1 and an outer frame 2, which can be freely retracted and extended to protect between layers, avoiding repeated disassembly and reassembly of the interlayer protective netting. It also includes a rectangular frame 3 and connecting components.

[0027] The rectangular frame 3 is set on the surface of the main structural layer 1 and is made of high-strength aluminum alloy material to reduce weight and improve corrosion resistance;

[0028] The connecting components include multiple connectors 5 sleeved on the outside of the outer frame 2. The rectangular frame 3 can be fixed to the outer frame 2 through the connectors 5, which facilitates installation and disassembly.

The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0031] The second embodiment of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0032] like Figures 2-4 As shown, multiple push-button hooks 4 are fixedly installed on the surface of the main structural layer 1, and a safety net 6 is fixedly installed inside the rectangular frame 3. The safety net 6 is snapped into the inside of the push-button hooks 4, and the push-button hooks 4 snap into the net surface, improving the firmness of the net surface on the structural layer. In addition, the safety net 6 is a commonly used large-mesh net, which can effectively intercept falling objects from high altitudes.

[0033] Furthermore, one end of the rectangular frame 3 is inserted into the interior of the connector 5. A pivot 7 is provided between the connector 5 and the rectangular frame 3. Multiple reflective strips 301 are fixedly installed on the surface of the rectangular frame 3. The rectangular frame 3 is fixed by the pivot 7 and can rotate clockwise and counterclockwise. The pivot 7 enables the free opening and closing of the interlayer flat net, and the installation of reflective strips 301 facilitates workers to observe the net surface.

[0034] The specific working method is as follows: The retractable interlayer flat net device is placed between the main structural layer 1 and the outer frame 2; one end of the rectangular frame 3 is inserted into the connector 5 and fixed by the pivot 7. The rectangular frame 3 is 500mm wider than the gap between the outer frame 2 and the main structural layer 1, and its length is the same as the side of the structure. The surface is fully covered with safety flat net 6. In addition, reflective strips 301 are installed on the surface of the frame, and press-type hooks 4 are installed on the structural layer. After the net is laid, the hooks are opened to fix the net. The rectangular frame 3 is fixed to the outer frame 2 by the pivot 7 and can rotate clockwise and counterclockwise. The retraction and deployment of the interlayer flat net can be achieved by the pivot 7.
