Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a prefabricated safety walkway device, which can be applied to the setting of safety walkways in the trench excavation scenario of old residential area renovation projects. It aims to solve the problems of repeated splicing, instability and unclear nighttime marking in the existing technology by optimizing the structural design and functional configuration of the walkway, so as to provide residents with safer and more convenient passage conditions. Background Technology

[0002] Currently, during the trench excavation process, temporary walkways are usually built to ensure the normal passage and safety of residents.

[0003] However, existing walkways, mostly connected by steel pipes and fasteners, have several shortcomings: First, their structural stability is poor, making them prone to swaying or deformation when pedestrians pass, failing to effectively guarantee pedestrian safety. Second, the installation and dismantling process is complex, requiring repeated splicing, consuming significant manpower and time, and reducing construction efficiency. Third, their functional design is relatively simple, especially lacking clear signage at night, making it difficult to meet the diverse needs of actual application scenarios, and easily leading to residents accidentally entering pipe trench areas and causing safety accidents, posing a significant safety hazard. Furthermore, most existing walkways are fixed structures, large in size, inconvenient to transport and store, and unable to meet the flexible needs of different construction scenarios.

[0004] Therefore, given the significant shortcomings of existing steel pipe fastener-type walkway structures in terms of stability, ease of installation, functional versatility, and applicability, there is an urgent need for a new type of safety walkway device that can ensure structural stability while enabling rapid installation and convenient transportation, and has functions such as nighttime warnings and real-time reminders, so as to comprehensively improve the safety and convenience of residents' passage during construction. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the traditional walkway structure in the existing technology, the purpose of this utility model is to provide a prefabricated safety walkway device, which has the advantages of reasonable structural design, convenient installation, use and transportation, high applicability, low maintenance cost, effective reduction of labor costs, improvement of on-site assembly efficiency and safety reliability, and convenient pedestrian passage.

[0006] To achieve the above objectives, this utility model adopts the following technical solution:

[0007] A prefabricated safety walkway device includes at least one prefabricated safety walkway component. Each prefabricated safety walkway component includes a left side plate, a right side plate, a base plate, a night warning light, and an alarm. The left side plate, right side plate, and base plate are all frame structures. Side plate protective components are provided in the frame structures of the left and right side plates. Base plate protective components are provided in the frame structure of the base plate. Several detachable connectors are provided on the left and right sides of the base plate, spaced apart along the length of the safety walkway. The left and right sides of the base plate are connected to the bottom of the sides of the left and right side plates respectively through the detachable connectors. The night warning light and alarm are provided on the sides of the left and / or right side plates. The detachable connectors include L-shaped steel plates and connecting latches. The horizontal plate of the L-shaped steel plate is provided at a reserved hole on the left or right side of the base plate side through the connecting latches. The vertical plate of the L-shaped steel plate is provided at a reserved hole on the left or right side of the left or right side plate corresponding to the horizontal plate position through the connecting latches. The connecting latches are threaded or snapped into the reserved holes.

[0008] As a further optimization of the above solution, the side panel protection component includes a protective railing or protective net installed within the left side panel frame structure; the bottom plate protection component includes a walkway panel installed within the bottom plate frame structure, and the surface of the walkway panel is also provided with anti-slip stripes.

[0009] As a further optimization of the above solution, the device also includes a PLC controller, which is connected to the night warning lights and alarm. The night warning lights are either solar-powered LED strobe lights equipped with solar panels or LED strobe lights equipped with dry batteries. The alarm is a PIR passive infrared alarm, a dual-beam or quad-beam active infrared beam alarm. Commonly used PLC controllers such as the Xinje XD1-16R (16-point relay output) or XD1E-14R (14-point relay output) can be selected, with the specific model chosen based on the actual design. Through the infrared sensing of the infrared alarm, the PLC controller can easily control the night warning lights and alarm to emit light and sound signals respectively to alert pedestrians on the safety walkway, thus improving the level of automation.

[0010] As a further optimization of the above scheme, a reinforcing rib is also provided between the horizontal and vertical plates of the L-shaped steel plate. The reinforcing rib is inclined between the horizontal and vertical plates and forms an isosceles right triangle with the horizontal and vertical plates. The frame structure of the left side plate, right side plate and bottom plate adopts a high-strength aluminum alloy frame.

[0011] The base plate has a flat or arched frame shape; correspondingly, the frames of the left and right side plates are adapted to the shape of the frame border of the base plate.

[0012] As a further optimization of the above solution, a drain outlet is also provided on the frame of the base plate, and the drain outlet is equipped with a removable filter screen.

[0013] As a further optimization of the above solution, an anti-detachment structure is also provided at the connection between the left and right side frames of the base plate and the bottom frames of the left and right side plates. The anti-detachment structure includes a fixing ring and a steel strand. The fixing ring is set at the same corresponding position on the left and right side frames of the base plate, the bottom frame of the left side plate, and the bottom frame of the right side plate. The two ends of the steel strand are fixed to the fixing rings on the bottom frame of the left side plate and the left side frame of the base plate, and the two ends of the steel strand are fixed to the fixing rings on the bottom frame of the right side plate and the right side frame of the base plate.

[0014] The prefabricated safety walkway device of this utility model has the following beneficial effects:

[0015] (1) The left side panel, right side panel, and bottom panel are made of high-strength aluminum alloy or lightweight steel as the main frame material, which has higher compressive strength and corrosion resistance, effectively reducing the shaking and deformation of the walkway during use and greatly improving the structural stability.

[0016] (2) The modular design, combined with hinges and quick-locking connection components, allows for the fixing of adjacent modules without additional tools. Compared to the repeated splicing required by traditional walkways, this significantly shortens installation and disassembly time, reduces labor costs, and improves construction efficiency. In addition, the modular design facilitates transportation and storage, and can flexibly adapt to various construction scenarios.

[0017] (3) By integrating nighttime warning devices (e.g., warning flashing lights or similar lighting structures that can serve as light signals for reminders) and alarm systems (e.g., infrared alarms or similar electrical components that can emit sound signals for reminders); specifically, nighttime warning devices solve the problem of traditional walkways lacking signage in low light conditions, providing clear boundary guidance for pedestrians and significantly improving nighttime traffic safety; alarm systems can promptly identify and issue warnings when pedestrians are passing by.

[0018] (4) The walkway panel adopts an anti-slip structure (for example, using anti-slip and wear-resistant materials or anti-slip and wear-resistant striped protrusions, combined with the bottom anti-slip pad design, which can effectively prevent pedestrians from falling due to the wet ground, especially in rainy and snowy weather conditions, further enhancing the practicality of the walkway).

[0019] (5) The modular design allows for adjustments to the length and width of the walkway based on actual design and usage needs. This makes it suitable not only for trench excavation in old residential area renovation projects but also for other construction sites, temporary passageways, and public facilities, significantly improving the overall applicability of the device. Considering the modular and independent design of each structural component, only the corresponding module needs to be replaced when damaged, eliminating the need for complete replacement and greatly reducing maintenance costs and improving the device's economic efficiency.

[0020] (6) The arched base frame can meet certain design requirements and also prevent water accumulation on the safety walkway; the drainage outlets reserved on the base frame can facilitate the drainage of water on the base, making it safer for pedestrians to pass.

[0021] (7) The anti-detachment structure, composed of a fixing ring and steel strand, can prevent the safety hazard caused by the loss of reliable connection between the left and right side plates and the bottom plate in the event of loosening of the detachable connectors. Maintenance personnel only need to periodically check whether the detachable connectors and the anti-detachment structure are loose, and the operation is relatively convenient.
