Description
Technical Field
[0001] This utility model belongs to the field of building engineering safety protection technology, and more specifically, it relates to a foldable safety guardrail for building construction. Background Technology
[0002] In the construction industry, safety barriers are indispensable facilities for ensuring construction safety. Their main functions are to demarcate construction areas, prevent unauthorized personnel from entering dangerous areas, and prevent construction workers from accidentally falling or being injured by falling objects. With the continuous development of the construction industry, higher requirements have been placed on the performance and ease of use of safety barriers; however, existing construction safety barriers have many shortcomings.
[0003] Traditional construction safety barriers are mostly one-piece structures, which are large and heavy. During transportation, their non-foldable nature occupies a significant amount of transport space, increasing transportation costs and difficulties. Furthermore, handling and moving them on the construction site is extremely inconvenient, requiring substantial manpower and time, severely impacting construction efficiency.
[0004] From an installation perspective, traditional guardrails are relatively complex to install, typically requiring specialized tools and significant manpower. In construction sites with complex terrain, such as slopes, uneven surfaces, or irregular shapes, traditional guardrails are difficult to adjust and install flexibly, resulting in a significant reduction in their protective effectiveness. Furthermore, once installed, if adjustments to the guardrail's position and layout are needed based on construction progress or site changes, the process of dismantling and reinstalling is not only cumbersome but also prone to damaging the guardrail, increasing maintenance costs.
[0005] In terms of warning function, most existing guardrails rely solely on surface warning signs to remind people to pay attention to safety. While these signs may be effective in well-lit daytime conditions, their effectiveness is greatly reduced at night or in dimly lit environments. Construction workers may find it difficult to clearly identify the location of the guardrails in a timely manner, thus increasing the risk of safety accidents such as collisions and falls.
[0006] Furthermore, traditional guardrails lack a monitoring and feedback mechanism for their own condition. Over long-term use, guardrails may become loose, deformed, or displaced due to external impacts, wind, sun, and other factors, but construction workers often fail to detect these potential safety hazards in a timely manner. When these problems accumulate to a certain extent, the guardrails may lose their protective function, potentially leading to safety accidents.
[0007] In summary, existing safety barriers used in construction have significant shortcomings in terms of transportation, installation, warning functions, and status monitoring, failing to meet the requirements of modern construction for safety, efficiency, and convenience. Therefore, developing a foldable safety barrier that is easy to install and adjust, possesses good warning functions, and can monitor its own status in real time is of great practical significance. Utility Model Content
[0008] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a foldable safety guardrail for construction, which is composed of multiple protective net units spliced together. Each protective net unit includes a protective net and a protective frame welded around the perimeter of the protective net. The protective frame includes a first frame, a second frame, an upper frame, and a lower frame.
[0009] The first frame is convex in shape, and its protruding part is provided with a through hole for mounting the pivot.
[0010] The No. 2 frame is concave in shape and has a pivot mounting hole corresponding to the No. 1 frame. The No. 1 and No. 2 frames can be connected to each other.
[0011] The upper and lower borders are located on the upper and lower sides of the protective netting, respectively, and are welded to the No. 1 and No. 2 borders to form a frame, which is used to frame the protective netting.
[0012] It also includes a pivot for splicing protective netting units. The pivot passes through the pivot mounting holes of frame 1 and frame 2, and the two are rotatably connected to realize the connection between protective netting units. By inserting the pivot, the protective netting units can be placed at any angle according to actual needs.
[0013] Preferably, the bottom of the No. 1 frame is provided with a foot, and the upper part of the foot is provided with a plug groove for easy installation of the pivot. By fixing the pivot into the plug groove of the foot, the quick splicing and disassembly of each protective net unit can be realized.
[0014] Preferably, an alarm component is provided on the top of the rotating shaft, the alarm component including a hexagonal box and a hexagonal truncated pyramid covering the top of the hexagonal box;
[0015] Solar panels are evenly distributed on the top and sides of the hexagonal truncated pyramid. A control circuit board, a storage battery, and an LED light strip are installed inside the hexagonal truncated pyramid. The inverter circuit on the control circuit board is used to convert the solar energy converted by the solar panels into electrical energy and store it in the storage battery. The storage battery provides power to the LED light strip.
[0016] A photosensitive sensor is installed on the outside of the hexagonal truncated pyramid. The photosensitive sensor is connected to the control circuit board and is used to collect information about the external light source. When the external light dims, the photosensitive sensor transmits the information to the control circuit board, and the control circuit board controls the LED light strip to light up.
[0017] The hexagonal box is made of transparent material, and the LED light strip is installed on the side inside the hexagonal box to provide light warning at night and ensure the safety of construction workers at night.
[0018] Preferably, the bottom of the foot is provided with mounting holes for easy insertion of ground nails, and the stability of the guardrail is further ensured by fixing the ground nails.
[0019] Preferably, a control module is also provided, the control module comprising:
[0020] The central processing unit is used to receive and process data from various sensors, as well as control the operation of various actuators;
[0021] The data storage unit, connected to the central processing unit, is used to store relevant data of the guardrail, including but not limited to the working records of the alarm component and ambient light intensity data;
[0022] The communication unit, connected to the central processing unit, is used for data communication with external devices and can send the working status information of the guardrail to the construction site management terminal.
[0023] The power management module, connected to the solar panel and battery, is used to manage the storage and distribution of electrical energy and control the power supply to various electrical components.
[0024] Preferably, the control module is also connected to an angle sensor, which is installed at the pivot point to monitor the splicing angle between the protective net units in real time and transmit the angle data to the central processing unit. The central processing unit determines the splicing status of the protective net based on the angle data, and sends an alarm message to the management terminal through the communication unit when the angle is abnormal.
[0025] Preferably, the control module is also connected to a displacement sensor, which is installed at the base or key parts of the protective frame to monitor the displacement of the guardrail. When the displacement exceeds a preset threshold, the central processing unit controls the alarm component to issue an alarm, and at the same time sends the displacement information to the management terminal through the communication unit.
[0026] Preferably, the control module analyzes the light intensity data collected by the photosensitive sensor. When the light intensity data remains at a low level for an extended period and the LED strip is not lit, the module automatically controls the LED strip to light up; when the light intensity data returns to normal, the module automatically controls the LED strip to turn off.
[0027] Preferably, the control module is equipped with a user interface for construction personnel to input the usage parameters of the guardrail. The user interface is connected to the central processing unit, which adjusts the working status of each component of the guardrail according to the parameters input by the user.
[0028] Compared with existing technologies, the beneficial effects of this utility model are:
[0029] 1. The guardrail is composed of multiple protective netting units spliced together via pivots. The convex and concave design of frame 1 and frame 2, along with corresponding pivot mounting holes, allows the protective netting units to be installed at any angle. Construction personnel can quickly and flexibly adjust the layout of the guardrail according to the actual terrain, shape of the construction area, and safety protection requirements, greatly improving the applicability and installation efficiency of the guardrail. It can be deployed in irregular sites or in areas requiring protection of different shapes, reducing pre-construction preparation time and difficulty.
[0030] 2. The bottom feet of frame 1 feature insertion slots for easy and quick installation of the pivots, simplifying the insertion and removal of the pivots. This eliminates the need for complex tools and cumbersome procedures in assembling and disassembling the guardrail, allowing construction workers to complete the work quickly. This not only improves construction efficiency but also facilitates the reuse and relocation of the guardrail, reducing construction costs.
[0031] 3. When construction is completed or the protected area needs to be temporarily adjusted, the protective netting unit can be easily folded or reversed simply by pulling out the ground nails. The folded protective fence occupies significantly less space and can also be completely disassembled for easy handling and storage, solving the problems of large size and difficult storage of traditional protective fences and improving space utilization.
[0032] 4. The solar panels of the warning unit can convert sunlight into electrical energy during the day and store it in the battery to power the LED light strip at night. This method of utilizing solar energy not only achieves energy self-sufficiency and reduces dependence on external power sources, but also ensures that the LED light strip can continue to emit light at night or in low-light conditions, providing stable warning lighting for the construction site.
[0033] 5. The photosensor installed on the exterior of the hexagonal truncated cone can collect external light source information in real time and automatically control the on / off state of the LED light strip according to the light intensity. When the external light dims, the LED light strip automatically lights up, providing a clear warning signal to construction workers, reminding them to pay attention to the position of the guardrail and avoid collision accidents; when the light returns to normal, the LED light strip automatically turns off, saving energy. This intelligent control method not only improves the warning effect but also extends the lifespan of the LED light strip and the battery.
[0034] 6. The hexagonal box is made of transparent material, with LED light strips mounted on its sides. This design allows the light to radiate from multiple angles, enhancing the warning effect. Whether viewed from the front, side, or from a distance, construction workers can clearly see the warning lights, improving construction safety.
[0035] 7. Anchor Support and Ground Peg Reinforcement: The anchor system provides stable support for the guardrail, increasing the contact area and friction between the guardrail and the ground, reducing the risk of the guardrail tipping over. The mounting holes at the bottom of the anchor facilitate the insertion of ground pegs, which, once deeply embedded in the ground, further enhance the guardrail's stability. Even under external impacts, such as strong winds or collisions, the guardrail remains stable and reliably performs its protective function.
[0036] 8. The angle and displacement sensors connected to the control module can monitor the splicing angle and displacement of the guardrail in real time. When the angle is abnormal or the displacement exceeds the preset threshold, the central processing unit can promptly control the alarm component to issue an alarm and send the alarm information to the construction site management terminal through the communication unit. This real-time monitoring and early warning function can promptly detect potential safety hazards in the guardrail and remind managers to take corresponding measures to ensure construction safety.

The pivot passes through the pivot mounting holes of frame 1 and frame 2, and rotates to connect the two to realize the connection between the protective netting units. By inserting the pivot 3, the protective netting units can be placed at any angle according to actual needs.
[0047] Preferably, the bottom of the No. 1 frame is provided with a foot 15, and the upper part of the foot 15 is provided with a plug groove for easy installation of the rotating shaft. By fixing the rotating shaft into the plug groove of the foot, the quick splicing and disassembly of each protective net unit can be realized.
[0048] Preferably, the top of the rotating shaft 3 is provided with an alarm component, which includes a hexagonal box 31 and a hexagonal truncated pyramid 32 covering the top of the hexagonal box.

[0050] The hexagonal truncated pyramid 32 is equipped with a photosensitive sensor on its exterior. The photosensitive sensor is connected to the control circuit board and is used to collect information about the external light source. When the external light dims, the photosensitive sensor transmits the information to the control circuit board, and the control circuit board controls the LED light strip to light up.

[0052] Preferably, the bottom of the foot 15 is provided with mounting holes for easy insertion of ground nails, and the stability of the guardrail is further ensured by fixing the ground nails.
[0053] Preferably, a control module 4 is also provided, the control module comprising:

[0057] The power management module 44 is connected to the solar panel and the battery to manage the storage and distribution of electrical energy and control the power supply to each electrical component.
[0058] Preferably, the control module is also connected to an angle sensor 45, which is installed at the pivot and is used to monitor the splicing angle between the protective net units in real time and transmit the angle data to the central processing unit.

[0059] Preferably, the control module is also connected to a displacement sensor 46, which is installed on the base or key parts of the protective frame to monitor the displacement of the guardrail. When the displacement exceeds a preset threshold, the central processing unit controls the alarm component to issue an alarm and sends the displacement information to the management terminal through the communication unit.
[0060] Preferably, the control module analyzes the light intensity data collected by the photosensitive sensor. When the light intensity data remains at a low level for an extended period and the LED strip is not lit, the module automatically controls the LED strip to light up; when the light intensity data returns to normal, the module automatically controls the LED strip to turn off.
[0061] Preferably, the control module is equipped with a user interface for construction personnel to input the usage parameters of the guardrail. The user interface is connected to the central processing unit, which adjusts the working status of each component of the guardrail according to the parameters input by the user.
[0062] The working principles of each part in the above embodiments are as follows:
[0063] I. Assembly and folding principles of guardrails:
[0064] Multiple protective netting units constitute a complete protective fence, with the protective frames within each unit playing a crucial connecting role. Frame 1 is convex, and frame 2 is concave, with corresponding pivot holes on either side. By inserting the pivot into these holes, frame 1 and frame 2 can be rotatably connected, allowing for flexible splicing of the protective netting units. Construction workers can place the units at any angle according to the actual site shape and layout requirements, quickly erecting a protective barrier. The insertion slots at the bottom of frame 1 facilitate easy pivot insertion and removal, greatly improving assembly and disassembly efficiency and facilitating the transfer, reuse, and storage of the protective fence. Furthermore, the bottom feet of frame 1 of each protective netting unit contact the ground, increasing friction and providing basic support to maintain the fence's upright position and prevent it from easily tipping over. Furthermore, the mounting holes at the bottom of the anchor point are used to insert ground stakes. Once the stakes are deeply embedded in the ground, they form a stable anchor point, further enhancing the overall connection strength between the guardrail and the ground. Even when subjected to external impacts, such as strong winds or collisions, the guardrail can still be firmly fixed in place, reliably providing protection.
[0065] When construction is completed or the protected area needs to be temporarily adjusted, simply pull out the pivot and remove the ground nails to fold and retract the protective net unit, reducing space occupation and making it easy to transport and store.
[0066] II. Working principle of the alert component
[0067] 1. Solar Energy Harvesting and Conversion: During the day or in well-lit environments, solar panels installed on the top and sides of the hexagonal truncated pyramid capture solar energy and convert it into electrical energy using the photovoltaic effect. An inverter circuit on the control board processes this electrical energy and stores it in a battery to achieve energy reserves, ensuring the power needs of subsequent components.
[0068] 2. Light Sensing and Lighting Control: An external light sensor on the hexagonal truncated cone monitors the ambient light intensity in real time. When the light gradually dims and reaches a preset light threshold, the light sensor transmits the light intensity change signal to the control circuit on the control board. Based on this signal, the control circuit connects the battery to the LED light strip, causing the LED light strip to illuminate and emit a bright light, providing a warning to personnel at the construction site and reminding them to pay attention to the guardrail location to avoid collisions. Conversely, when the light brightens again and returns to normal intensity, the light sensor sends a signal, the control circuit cuts off the circuit, and the LED light strip turns off, saving energy.
[0069] III. Working principle of the control system (This is not a key part of the protection application, so it will be briefly described).
[0070] S1. Data Acquisition: Angle sensors are installed at the pivot to continuously monitor the splicing angle between the protective net units. Displacement sensors are installed at the base or key parts of the protective frame to sense the displacement of the protective fence in real time. Photosensitive sensors continuously feed back ambient light intensity data. These sensors transmit the collected data to the central processing unit in the control module.
[0071] S2. Data Processing and Judgment: After receiving the data, the central processing unit compares it with the preset normal parameter range. If the angle data deviates from the normal splicing angle range, it is determined that the guardrail may be improperly assembled or at risk of being twisted or deformed by external forces; if the displacement data exceeds the set displacement threshold, it means that the guardrail may have suffered a large external impact and is at risk of collapse; when abnormal situations occur such as the light intensity data meeting the dim light conditions and the LED light strip not being lit, or the light intensity returning to normal but the LED light strip still being lit, the central processing unit responds immediately.
[0072] S3. Control and Communication: In response to the aforementioned anomaly detection, the central processing unit (CPU) directly controls the actions of relevant components, such as turning LED lights on or off. Simultaneously, it sends alarm information to the construction site management terminal via the communication unit, including details such as the type and location of the anomaly in the guardrail, allowing management personnel to be promptly informed and take appropriate repair and reinforcement measures. Meanwhile, the data storage unit records various data throughout the process, including sensor readings and component operating status, providing a basis for subsequent analysis of guardrail performance and tracing the root cause of problems. The user interface allows construction personnel to input personalized parameters for the guardrail as needed, such as adjusting the light intensity trigger threshold and setting specific alarm modes. The CPU optimizes the guardrail's operation control strategy in real time based on these inputs.
[0073] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
