Description

Technical Field

[0001] This utility model relates to the field of climbing scaffold fall prevention technology, specifically to a building construction safety fall prevention device. Background Technology

[0002] Climbing scaffolding, also known as lifting scaffolding, can be mainly classified into hydraulic, electric, and manual types based on its power source. It is a new type of scaffolding system developed in recent years, primarily used in high-rise shear wall buildings. It can ascend or descend along the building. This system completely revolutionizes scaffolding technology: firstly, it eliminates the need to dismantle and reassemble the scaffolding; secondly, it eliminates the dismantling and assembly process (once assembled, it is used until construction is completed), and it is not limited by the building's height, greatly saving manpower and materials. Furthermore, it offers significant improvements in safety compared to traditional scaffolding. It has great advantages in high-rise buildings, and to improve the safety factor, fall arrestors are generally installed at the climbing scaffolding points.

[0003] A search revealed that patent application number CN202421425168.2 discloses a climbing scaffold fall prevention and fixing safety device. Although this device uses a fall prevention fixing mechanism and a fall prevention rack, when the climbing scaffold falls, the lower wall of the toothed part presses against the upper wall of the fall prevention bar, and the guide groove restricts the fall to achieve the fall prevention function, and the structure is simple and the cost is low, the device has a relatively single function when in use. It only serves to block the climbing scaffold from falling and lacks monitoring and protective response to changes in the surrounding environment. It cannot cope with other unexpected situations such as impacts from falling objects from heights, and it is difficult to comprehensively protect the safety of construction personnel. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a safety fall prevention device for building construction, which solves the problems mentioned in the background technology.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A safety fall arrest device for building construction includes a base plate, and a surrounding plate is provided on the upper surface of the base plate;

[0007] A support rod is welded to the bottom plate on the inner side of the enclosure. A top plate is welded to the bottom plate via the support rod. An airbag seat is installed on the inner surface of the enclosure. A side air curtain is provided on the airbag seat. A lower airbag and an upper airbag are respectively provided on the lower surface of the bottom plate and the lower surface of the top plate.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the airbag seat is equipped with a handrail.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The handrails provide construction workers with stable gripping points, helping them maintain balance inside the equipment and preventing accidental falls due to factors such as shaking of the construction environment or unstable walking, thus reducing the risk of accidental falls from the equipment. At the same time, in the event of a fall accident around the equipment, construction workers can quickly grab the handrails to stabilize their position and prevent chain reactions caused by the fall from endangering their own safety, thus enhancing the equipment's safety protection capabilities and human-centered design.

[0012] Furthermore, an acceleration sensor and a controller are installed on the base plate, and the lower airbag, side curtain airbag and upper airbag are all connected to the acceleration sensor through the controller.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] By monitoring real-time acceleration changes around the equipment using accelerometers, abnormal acceleration signals generated at the moment of impact can be accurately captured and quickly transmitted to the controller. The controller analyzes and processes the signals based on a preset program, promptly and accurately activating the lower airbag, side curtain airbag, and upper airbag, forming an automated and intelligent protective response mechanism. This design replaces traditional manual judgment or simple mechanical triggering methods, greatly improving the timeliness and accuracy of protective equipment activation. It effectively reduces protective failures caused by reaction delays or misjudgments, significantly enhancing the equipment's safety protection effectiveness.

[0015] Furthermore, the controller has a built-in delay trigger module. When the acceleration detected by the acceleration sensor exceeds a preset threshold, the controller controls the lower airbag, side curtain airbag and upper airbag to start inflating after 0.3-0.5 seconds through the delay trigger module. The delay trigger module is electrically connected to the controller.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The introduction of the delay-triggered module effectively solves the problem of airbag false triggering caused by non-fall factors such as normal vibrations and brief equipment shaking during construction. After the accelerometer detects an abnormal acceleration signal, the delay-triggered module filters out transient, non-continuous interference signals through a short delay of 0.3-0.5 seconds, ensuring that the airbags and side curtain airbags are only inflated when a real fall accident occurs and the abnormal acceleration is persistent. This design significantly improves the reliability and stability of the equipment, reduces frequent airbag inflation and wear caused by false triggering, lowers equipment maintenance costs, and avoids unnecessary panic and interference to construction personnel due to false triggering, ensuring the normal and orderly progress of construction.

[0018] Furthermore, the top plate is made of honeycomb aluminum alloy with a thickness of 15-20mm, and the top plate and the support rod are connected by a double connection method of welding and bolt fixing. The bolts are stainless steel bolts with a strength grade of 8.8, and no less than 8 are evenly distributed along the edge of the top plate.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] The honeycomb aluminum alloy material combines lightweight and high strength, reducing the overall weight of the equipment for easier transportation and installation, while withstanding external forces such as falling objects from heights and personnel climbing during construction, ensuring the safety of the equipment's top structure. The 15-20mm thickness design achieves efficient material utilization and cost optimization while meeting strength requirements. The dual connection method of welding and bolting ensures a more robust and reliable connection between the top plate and support rods. Welding guarantees the structural integrity and initial strength, while high-strength stainless steel bolts provide additional security and facilitate later disassembly, inspection, and maintenance. At least eight bolts are evenly distributed along the edge of the top plate to ensure uniform stress distribution, effectively dispersing external loads, enhancing the overall structural stability and impact resistance of the equipment, and significantly reducing the risk of safety accidents caused by top plate structural failure.

[0021] This utility model provides a safety fall prevention device for building construction. It has the following beneficial effects:

[0022] The base plate is welded to the top plate via support rods, and the top plate and support rods are connected by a double method of welding and bolt fixing. The bolts are high-strength stainless steel bolts, and there are no less than 8 bolts evenly distributed along the edge of the top plate. This design can ensure the stability and firmness of the overall structure of the equipment, withstand a certain amount of external impact, and ensure safety during construction.

[0023] The top plate is made of honeycomb aluminum alloy with a thickness of 15-20mm. Honeycomb aluminum alloy has the advantages of being lightweight, high-strength, and corrosion-resistant, which can reduce the overall weight of the equipment while ensuring that the top plate has sufficient strength to withstand possible falling impacts.

[0024] Airbag seats are installed on the inner surface of the enclosure, with side curtain airbags mounted on them. Lower airbags and upper airbags are respectively installed on the lower surface of the bottom and top panels. All these airbags and side curtain airbags are connected to an acceleration sensor via a controller. When the acceleration sensor detects abnormal acceleration, it will control all airbags and side curtain airbags to inflate rapidly, forming a comprehensive buffer protection that can effectively reduce the impact force on people or objects falling and reduce the degree of injury.

[0025] The controller has a built-in delay trigger module. When the acceleration detected by the acceleration sensor exceeds a preset threshold, the controller uses the delay trigger module to control the airbags and side curtain airbags to inflate after 0.3-0.5 seconds. This delay design can avoid false triggering of the airbags due to some brief, non-fall-related acceleration changes, improving the reliability and accuracy of the equipment and ensuring that it can play a timely and effective protective role in the event of a real fall accident.

[0026] The airbag seat is equipped with a handrail, providing a convenient grip for construction workers. This helps them maintain stability inside the equipment and prevents falls due to shaking or accidents, demonstrating a human-centered approach to construction workers and further improving the safety and practicality of the equipment.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:

[0035] Example 1

[0036] A construction safety fall arrest device includes a base plate 1, with a surrounding plate 2 on the upper surface of the base plate 1. A support rod 5 is welded to the inner side of the surrounding plate 2 on the base plate 1. A top plate 4 is welded to the base plate 1 via the support rod 5. The top plate 4 is made of honeycomb aluminum alloy with a thickness of 15-20mm. The top plate 4 and the support rod 5 are connected by a double connection method of welding and bolts. The bolts are 8.8 grade stainless steel bolts, with at least eight evenly distributed along the edge of the top plate 4. The honeycomb aluminum alloy material combines lightweight and high strength, reducing the overall weight of the equipment, facilitating transportation and installation, while withstanding external forces such as impacts from falling objects and personnel climbing during construction, ensuring the safety of the top structure of the equipment. The 15-20mm thickness design achieves rational material utilization and optimizes costs while meeting strength requirements. The dual connection method of welding and bolt fixing makes the connection between the top plate 4 and the support rod 5 more robust and reliable. Welding ensures the integrity and initial strength of the structure, while high-strength stainless steel bolts provide additional fastening protection and facilitate the disassembly, inspection and maintenance of the equipment in the later stage. No less than 8 bolts are evenly distributed along the edge of the top plate 4 to ensure uniform force distribution, effectively disperse external loads, enhance the stability and impact resistance of the overall structure of the equipment, and significantly reduce the risk of safety accidents caused by the failure of the top plate 4 structure.

[0037] Example 2

[0038] To further improve the protective performance and reliability of fall protection equipment in building construction and to maximize the safety of construction workers, for example, such as Figures 1 to 5As shown, this utility model also includes: an airbag seat 3 installed on the inner surface of the enclosure 2, and a handrail 302 provided on the airbag seat 3. The handrail 302 provides a stable gripping point for construction workers, helping them maintain balance inside the equipment and preventing accidental falls due to factors such as shaking of the construction environment or unstable walking, thus reducing the risk of accidental falls from the equipment. At the same time, in the event of a fall accident around the equipment, construction workers can quickly grab the handrail 302 to fix their position and prevent chain reactions caused by the fall from endangering their own safety. This design enhances the equipment's safety and user-friendly features. The airbag base 3 is equipped with side curtain airbags 301. The lower surface of the base plate 1 and the lower surface of the top plate 4 are respectively equipped with a lower airbag 101 and an upper airbag 401. An acceleration sensor and controller are installed on the base plate 1. The lower airbag 101, side curtain airbags 301, and upper airbag 401 are all connected to the acceleration sensor via the controller. The acceleration sensor monitors real-time acceleration changes around the equipment, accurately capturing abnormal acceleration signals generated during a fall and rapidly transmitting them to the controller. The controller analyzes and processes the signals based on a preset program, promptly and accurately activating the lower airbag 101, side curtain airbags 301, and upper airbag 401, forming an automated and intelligent protection response mechanism. This design replaces traditional manual judgment or simple mechanical triggering methods, greatly improving the timeliness and accuracy of protective equipment activation. It effectively reduces protective failures caused by reaction delays or misjudgments, significantly enhancing the equipment's safety performance. The controller has a built-in delay trigger module. When the acceleration detected by the accelerometer exceeds a preset threshold, the controller uses the delay trigger module to control the lower airbag 101, side curtain airbag 301, and upper airbag 401 to inflate after 0.3-0.5 seconds. The delay trigger module is electrically connected to the controller. The introduction of the delay trigger module effectively solves the problem of false airbag triggering caused by non-fall factors such as normal vibrations and brief equipment shaking during construction. After the accelerometer detects an abnormal acceleration signal, the delay trigger module uses a short delay of 0.3-0.5 seconds to filter out instantaneous, non-continuous interference signals, ensuring that the airbags and side curtain airbags 301 are only inflated when a real fall accident occurs and the abnormal acceleration persists. This design significantly improves the reliability and stability of the equipment, reduces frequent inflation and wear of the airbags due to accidental triggering, lowers equipment maintenance costs, and avoids unnecessary panic and interference to construction personnel due to accidental triggering, ensuring the normal and orderly progress of construction.

[0039] Working principle:

[0040] The equipment is in normal working condition, and all components are ready. The base plate 1, the surrounding plate 2, the support rod 5, and the top plate 4 form a stable frame structure. The honeycomb aluminum alloy top plate 4, with its high strength and lightweight characteristics, provides stable top support for the equipment. On the airbag seat 3 inside the surrounding plate 2, the handrail 302 can be used by construction personnel to hold on, ensuring the stability of personnel inside the equipment.

[0041] When a person or object falls during construction, the acceleration sensor installed on the base plate 1 will monitor the acceleration changes of the surrounding environment in real time. Once the detected acceleration exceeds a preset threshold, it means that a fall accident may have occurred, and the acceleration sensor will immediately transmit the signal to the controller.

[0042] After receiving the signal from the accelerometer, the built-in delay trigger module of the controller begins to function. It performs a brief 0.3-0.5 second delay on the signal to prevent false triggering of the airbag due to brief, non-fall-related acceleration changes (such as normal vibrations during construction). This ensures that protective measures are activated only in the event of a real fall accident, improving the reliability and accuracy of the equipment.

[0043] After a delayed assessment confirms it is a fall accident, the controller quickly issues commands to inflate the lower airbag 101, side curtain airbag 301, and upper airbag 401. The side curtain airbag 301, located inside the enclosure 2, forms a buffer barrier from the side during a fall; the lower airbag 101, installed on the lower surface of the base plate 1, catches falling objects and reduces the impact force upon landing; the upper airbag 401, located on the lower surface of the top plate 4, prevents impact from above during a fall. These three elements work together to provide comprehensive cushioning protection, effectively reducing the impact force on personnel or objects falling and minimizing the severity of injury.

[0044] Once the impact of the fall has dissipated and the airbag has completed its buffering function, the equipment enters the subsequent processing stage. The airbag can be deflated, inspected, and maintained according to the actual situation so that the equipment can continue to be put into use.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
