Description

Technical Field

[0001] This invention belongs to the field of construction site fencing technology, specifically, it relates to a suspended safety fencing that does not affect ground construction. Background Technology

[0002] In the construction industry, safety barriers are key facilities for ensuring work safety and isolating construction areas. Especially in scenarios with suspended structures such as corridors and platforms, the protective performance, adaptability, and convenience of the barriers directly affect construction efficiency and safety levels. Traditional safety barriers are mostly fixed to the ground, which requires occupying the ground surface space of corridors, platforms, and other areas.

[0003] During floor construction (such as grinding, pouring, and drying), to avoid obstructing construction operations, the fencing needs to be completely removed or temporarily moved. This results in the complete exposure of suspended areas, leaving construction workers without protection, which greatly increases the risk of falls. This creates a dilemma where construction and protection are mutually exclusive: either sacrifice construction efficiency to retain the fencing, or abandon protection to advance construction, making it impossible to achieve full-process safety protection. At the same time, there are often gaps between the bottom of traditional fencing and the building structure, allowing stones and tools generated during construction at heights to fall through these gaps, posing a secondary safety hazard to personnel passing below or working below.

[0004] like Figure 1 As shown, some high-rise frame buildings currently have high-altitude corridors with platforms at both ends and suspended areas on both sides. Therefore, it is necessary to place barriers on the corridors and platforms near the suspended areas to prevent people from falling and to ensure the safety of construction workers.

[0005] Chinese utility model patent CN222184381U discloses a safety protection building fence, including: a first pillar and a second pillar. Two connecting cylinders are connected to one side of the first pillar, and two docking cylinders are connected to one side of the second pillar relative to the first pillar. The connecting cylinders and docking cylinders are interconnected. Multiple first baffles are symmetrically connected between the two connecting cylinders. By setting a telescopic component structure, when it is necessary to adjust the length of the fence, the screw is turned so that the screw rotates through the bearing. Since the limiting plate is threadedly connected to the screw, the limiting plate drives the docking cylinder to move on the screw, so that the docking cylinder extends and retracts from one end of the connecting cylinder.

[0006] While the fence facilitates its storage, its installation presents multiple challenges in a suspended high-altitude corridor setting, impacting subsequent construction and the surrounding environment. Installing the fence above the corridor directly interferes with subsequent flooring work. Furthermore, the fence's retractable structure inevitably introduces gaps. Additionally, the corridor surface must be cleaned and polished before flooring construction to achieve the required roughness; the noise generated during this process can easily diffuse through the fence gaps and the corridor's suspended structure, significantly disrupting the daily lives of nearby residents. Summary of the Invention

[0007] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0008] To address the multiple issues raised in the background section regarding the installation of fencing in elevated walkways with suspended sides, which involve interference with subsequent construction and the surrounding environment—namely, the direct interference with subsequent flooring construction if the fencing is installed at the top of the walkway; the inherent gaps in the retractable fencing structure; and the need for cleaning and polishing the walkway surface before flooring construction to ensure the required roughness, which generates noise that easily diffuses through the gaps in the fencing and the suspended structure of the walkway, ultimately causing significant disruption to the daily lives of nearby residents—this invention employs the following technical solution.

[0009] A suspended safety enclosure that does not affect ground construction includes a protective frame installed on the outer wall of a corridor or platform. The protective frame has a sound insulation section inside. The protective frame includes vertical frames and horizontal frames. The vertical frames are detachably connected to both ends of the horizontal frames. The sound insulation section includes an adjustment plate. The adjustment plate is rotatably connected between the two vertical frames. There are multiple adjustment plates between the two vertical frames. The rotation of the multiple adjustment plates can close or open the interior of the protective frame for ventilation.

[0010] Preferably, each of the adjustment plates has multiple honeycomb holes on its outer wall, and each adjustment plate has an air layer located deep inside the honeycomb holes. Noise enters the interior of the honeycomb holes and causes the air inside the honeycomb holes to vibrate and rub against the inner wall of the honeycomb holes, converting sound energy into heat energy and consuming it. The air layer adds a resonant cavity.

[0011] Preferably, each adjusting plate is fixedly connected to a rubber sealing plate near the lower outer wall. When multiple adjusting plates rotate and close, the rubber sealing plate fills the gap between the multiple adjusting plates.

[0012] Preferably, the outer walls of the two vertical frames near the bottom are provided with molded plates, which can be adjusted in height and fit the outer wall of the corridor or platform.

[0013] Preferably, the outer wall of the vertical frame on both sides near the bottom is provided with a sliding groove, and a sliding block is slidably connected inside the sliding groove. The mold plate is connected to the outer wall of the sliding block on both sides, and a fastening bolt is threaded on the sliding block. Loosening the fastening bolt allows the sliding block on both sides to slide inside the sliding groove, thereby adjusting the height of the mold plate.

[0014] Preferably, each of the adjusting plates has a transmission rod fixedly connected to both ends, extending through the adjacent vertical frame. The interior of the two vertical frames is provided with a cavity. The transmission rod is detachably connected to a meshing gear on the outer wall of the cavity. A strong magnetic plate is provided on the inner wall of the cavity. A driving rack is magnetically attracted to the outer wall of the strong magnetic plate. The driving rack is completely in contact with the inner wall of the cavity. The driving rack meshes with multiple meshing gears in the same cavity. The magnetic force of the strong magnetic plate is greater than the offset force of the adjusting plate due to gravity. When a single meshing gear rotates, it causes the driving rack to move up and down in the cavity, driving the other meshing gears to rotate.

[0015] Preferably, a hexagonal head is fixedly connected to the protruding end of the transmission rod of one side of the vertical frame, and a hexagonal groove is provided at the protruding end of the transmission rod of the other side of the vertical frame. Multiple protective frames in the same row are fitted side by side, so that the hexagonal head is inserted into the interior of the hexagonal groove.

[0016] Preferably, the magnetic attraction surfaces of the drive rack and the strong magnetic plate are provided with a frosted layer, which increases the friction between the drive rack and the strong magnetic plate.

[0017] Preferably, it also includes a connecting part, the bottom of the vertical frame is provided with a second inclined surface, the outside of the second inclined surface is fixedly connected with a downwardly extending part, the outer wall of the vertical frame is provided with a rotating part, the connecting part and the vertical frame rotate along the rotating part, the outer wall of the connecting part is provided with a first inclined surface that is the same as the second inclined surface, the first inclined surface is provided with a plurality of inner grooves, and expansion bolts pass through the inside of the inner grooves.

[0018] Preferably, the upper end of the connecting part is provided with a support platform, and the mold plate moves downward so that the bottom fits with the upper end of the support platform, and the mold plate covers the rotating part.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In this invention, the protective frame is installed on the side wall of the corridor or platform rather than on the surface. It does not need to be removed during floor construction, avoiding complete exposure of the suspended area due to the removal of the fence. This fundamentally eliminates the risk of workers falling, allowing construction and protection to proceed simultaneously. When the adjustable plate is closed, it can block the transmission of construction noise. In conjunction with the rubber sealing plate, it fills the gaps between the plates and forms a resonance chamber, further weakening the sound energy. After the floor construction, the airflow can be controlled by adjusting the opening and closing angle of the adjustable plate, preventing the floor from cracking due to excessive drying speed. At the same time, in windy weather, the adjustable plate can guide the airflow, reducing the impact of strong winds on the fence and preventing the fence from falling off.

[0021] 2. In this invention, the honeycomb holes on the outer wall of the adjustment plate and the inner air layer form a sound-absorbing combination: after noise enters the honeycomb holes, the air vibration and friction with the hole wall convert the sound energy into heat energy, and the air layer weakens the sound energy a second time, greatly reducing the noise interference of grinding and other processes to the surrounding environment.

[0022] 3. In this invention, the dust generated during grinding can enter the air layer and settle through the honeycomb holes; during cleaning, it is only necessary to rotate the adjustment plate to make the honeycomb holes face downwards, and the dust can be discharged to the outside of the building along the inclined plate without dismantling the enclosure, thus reducing cleaning costs and dust pollution.

[0023] 4. In this invention, the drive rack and meshing gear work together to simultaneously adjust all the adjustment plates within a single enclosure; the magnetic force of the strong magnetic plate and the frosted layer of the magnetic attraction surface can firmly fix the posture of the adjustment plate, prevent displacement during construction, and ensure adjustment accuracy.

[0024] 5. In this invention, the same row of fences are linked by the hexagonal head and hexagonal groove. Rotating any one of the hexagonal heads can drive the adjustment plates of all fences to rotate synchronously, eliminating the need for individual adjustment and greatly saving operation time. It is especially suitable for large-scale construction scenarios with long corridors and large platforms.

[0025] 6. In this invention, the fence can be laid flat on the building surface, first fixed by the inner groove of the connecting part and the expansion bolt, and then rotated around the rotating part to a vertical state, without the need for hoisting equipment or multiple people to lift it, thus reducing labor and equipment costs.

[0026] 7. In this invention, the support platform of the connecting part cooperates with the mold plate. After the mold plate moves down, it fits the support platform, which can lock the rotating part, prevent the fence from rotating and loosening after installation, simplify the fixing process, and improve the installation stability.

[0045] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0047] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0048] Example 1

[0049] like Figures 2 to 4 The diagram shows a preferred embodiment of the present invention of a suspended safety barrier structure that does not affect floor construction. This embodiment of the suspended safety barrier includes a protective frame 200, with a sound insulation section 300 inside. The protective frame 200 is installed on the side walls of the corridor 100 and the outer wall of the platform 101 at the suspended location. In this embodiment, by installing the protective frame 200 on the side walls of the corridor 100 or platform 101, the surface of the corridor 100 and platform 101 is not occupied during floor construction above them. Therefore, the protective frame 200 does not need to be removed, allowing the corridor 100 to still provide protection during floor construction. This avoids the situation where the protective frame 200 is removed during floor construction, resulting in complete exposure of the suspended area and potential falls by construction workers.

[0050] like Figure 5As shown, this is a schematic diagram of the suspended safety barrier structure in this embodiment. The protective frame 200 includes vertical frame 201 and horizontal frame 202. The vertical frame 201 is detachably connected to both ends of the horizontal frame 202. The outer walls of the two vertical frames 201 near the bottom are detachably connected to the outer walls of the corridor 100 or platform 101. The sound insulation part 300 includes adjusting plates 301. Multiple adjusting plates 301 are rotatably connected between the two vertical frames 201. In this embodiment, before laying the floor on the platform 101 or corridor 100, the surface of the platform 101 or corridor 100 needs to be polished to remove surface oil and increase the roughness. The roughness allows multiple adjusting plates 301 to fit together, effectively reducing noise transmission during the treatment of the corridor 100 and platform 101 surfaces, and minimizing the impact of noise on the surrounding environment. After the floor is constructed, it needs to be dried. However, if the drying speed is too fast, the floor will crack. Therefore, the drying speed of the floor can be controlled by adjusting the rotation angle of the adjusting plates 301 and adjusting the opening and closing size between each pair of adjusting plates 301. This allows air to pass through the gaps between each pair of adjusting plates 301 and also guides the wind in windy weather, preventing the protective frame 200 from falling off.

[0051] like Figure 5 As shown, in order to reduce noise reflection, the following implementation method can be adopted: the outer wall of each adjustment plate 301 is provided with a plurality of honeycomb holes 302, and an air layer 310 is provided deep inside the honeycomb holes 302 of each adjustment plate 301. In this embodiment, noise enters the interior of the honeycomb holes 302 and causes the air inside the honeycomb holes 302 to vibrate and rub against the inner wall of the honeycomb holes 302, converting sound energy into heat energy and consuming it. The air layer 310 can further weaken the sound energy, achieving a good sound absorption effect. When the surface of the corridor 100 and the platform 101 is treated, dust can enter the interior of the air layer 310 through the honeycomb holes 302 for collection and sedimentation. When it is necessary to clean the dust inside the air layer 310, each adjustment plate 301 is rotated to tilt to the other side. At this time, the honeycomb holes 302 are tilted downwards, and the dust inside the air layer 310 can be discharged outwards through the honeycomb holes 302 and discharged to the outside of the corridor 100 through the tilted adjustment plate 301.

[0052] like Figure 5 As shown, in order to achieve a better seal between the multiple adjustment plates 301 when closed and to reduce the risk of sound transmission, the following implementation method can be adopted: each adjustment plate 301 is fixedly connected to a rubber sealing plate 303 near its lower outer wall. In this embodiment, the rubber sealing plate 303 can fill the gaps between the multiple adjustment plates 301 when they rotate and close, and can also increase a resonance chamber, further enhancing the sound absorption effect.

[0053] As shown Figure 6 in the figure, it is a schematic enlarged structure diagram of the position A in this embodiment. On the outer walls of the two vertical side frames 201 near the lower part, sliding grooves 204 are provided. Inside the sliding grooves 204, sliding blocks 205 are slidably connected. On the outer walls of the two sliding blocks 205, formwork plates 203 are fixedly connected. Threaded fasteners 206 are connected to the sliding blocks 205. In this embodiment, through the formwork plates 203, the gaps between the protective frame body 200 and the corridor 100 or the platform 101 can be filled, and it can act as a template to assist in the shaping of the floor slab. And when the protective frame body 200 is arranged at a position where floor construction is not required, it can reduce the risk that the stones at a high place fall downward through the bottom of the protective frame body 200. By loosening the threaded fasteners 206, the height of the formwork plate 203 can be adjusted, and thus it can be adjusted according to the thickness of the floor slab.

[0054] As shown Figure 11 in FIGS. 11 and 12, in order to be able to adjust the rotation and opening / closing of the adjusting plate 301, the following implementation manner can be adopted. At both ends of each adjusting plate 301, transmission rods 304 penetrating through the adjacent vertical side frames 201 are fixedly connected. Inside the two vertical side frames 201, cavities are provided. On the outer walls of the transmission rods 304 located in the cavities, meshing gears 305 are detachably connected. On the inner walls of the cavities, strong magnetic plates 309 are provided. On the outer walls of the strong magnetic plates 309, driving racks 308 are magnetically attracted. The driving racks 308 are completely in contact with the inner walls of the cavities. The driving racks 308 are meshed with a plurality of meshing gears 305 in the same cavity. The magnetic force of the strong magnetic plates 309 is greater than the offset force generated by the gravity of the adjusting plate 301 to ensure stable posture after adjustment. On the magnetic attraction surfaces of the driving racks 308 and the strong magnetic plates 309, a matte layer is provided. In this embodiment, by moving the driving racks 308 up and down, each meshing gear 305 is driven to rotate, and thus the rotation of the adjusting plates 301 inside each protective frame body 200 can be adjusted simultaneously. And through the magnetic attraction of the strong magnetic plates 309, the posture of the adjusting plates 301 can be fixed. Through the matte layer, the friction force between the driving racks 308 and the strong magnetic plates 309 can be increased, making the posture of the adjusting plates 301 more stable.

[0055] In order to cause a linkage between a plurality of sound insulation parts 300 arranged in sequence and realize the simultaneous rotation of each adjusting plate 301 in the same row at the same time, the following can be adopted as shown Figure 6 in Figure 10 and Figure 12 ​​In the illustrated embodiment, a hexagonal head 307 is fixedly connected to the protruding end of the transmission rod 304 on one side of the vertical frame 201, and a hexagonal groove 306 is provided at the protruding end of the transmission rod 304 on the other side of the vertical frame 201. During installation, multiple protective frames 200 in the same row are placed side by side, and the hexagonal head 307 is inserted into the interior of the hexagonal groove 306. In this embodiment, by using a tool to rotate any one of the hexagonal heads 307, a meshing gear 305 inside a vertical frame 201 can be rotated. The rotation of the meshing gear 305 drives the drive rack 308 to move upward or downward inside the cavity, thereby driving other meshing gears 305 to rotate. In conjunction with the insertion of the hexagonal head 307 into the hexagonal groove 306, the adjustment plates 301 on other protective frames 200 are driven to rotate simultaneously, thereby achieving the purpose of adjusting multiple adjustment plates 301 to rotate simultaneously at one time, making adjustment more convenient.

[0056] Example 2

[0057] like Figure 13 As shown, this is a schematic diagram of the installation component structure of another preferred embodiment of the present invention. The difference between this embodiment and embodiment 1 is that a second inclined surface 406 is provided at the bottom of the vertical frame 201, and a downwardly extending extension 407 is fixedly connected to the outside of the second inclined surface 406. A rotating part 402 is provided on the outer wall of the vertical frame 201, and a connecting part 400 is installed on the rotating part 402. The connecting part 400 and the vertical frame 201 rotate along the rotating part 402. A first inclined surface 405, which is the same as the second inclined surface 406, is provided on the outer wall of the connecting part 400. A plurality of inner grooves 404 are provided on the first inclined surface 405. The expansion bolt 403 passes through the interior of 4 and is connected to the side wall of the corridor 100 or platform 101. In this embodiment, holes are drilled in advance on the corresponding outer wall of the corridor 100 or platform 101. The protective frame 200 is laid flat on the surface of the corridor 100 or platform 101, so that the connecting part 400 rotates downward to fit against the outer wall of the corridor 100 or platform 101, so that the inner groove 404 is aligned with the hole and the expansion bolt 403 is inserted for fixation. Then the protective frame 200 is rotated to the vertical direction so that the protective frame 200 does not need to be hoisted or manually lifted when installing it, making the installation more convenient.

[0058] like Figure 13 As shown, in order to ensure that the vertical frame 201 and the connecting part 400 are fixed and no longer rotate, in this embodiment, a support platform 401 is provided at the upper end of the connecting part 400. The mold plate 203 moves downward so that the bottom is in contact with the upper end of the support platform 401. At this time, the mold plate 203 covers the rotating part 402, thereby preventing the vertical frame 201 and the connecting part 400 from rotating, making the fixing more convenient.

[0059] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
