Description

Technical Field

[0001] This utility model relates to the field of construction technology, and in particular to a prefabricated safety fence for slope protection at construction sites. Background Technology

[0002] With the booming development of the construction industry, various construction projects are springing up like mushrooms after rain. As a key link in ensuring construction safety and preventing landslides, slope protection is becoming increasingly important. During slope protection construction, setting up safety barriers is an important measure to prevent non-construction personnel from accidentally entering dangerous areas and to reduce the impact of construction on the surrounding environment.

[0003] Traditional slope protection safety fencing often employs methods such as on-site welding, scaffolding erection, or direct fixing of metal frames. These methods have numerous drawbacks. Firstly, the construction process is complex, requiring significant manpower, resources, and time, leading to low construction efficiency and impacting the overall project progress. Secondly, traditional fencing has poor stability, making it prone to deformation and collapse in severe weather or external impacts, posing safety hazards to construction workers and nearby residents. Furthermore, after dismantling traditional fencing, the materials are difficult to recycle and reuse, resulting in resource waste and generating substantial construction waste that pollutes the environment.

[0004] With the rise of prefabricated building technology, prefabricated safety barriers, with their standardized, modular, and reusable characteristics, are gradually becoming a new choice for safety protection on construction sites. However, in the special scenario of slope protection, how to ensure a stable connection between prefabricated safety barriers and existing or newly poured concrete structures, while avoiding damage to the original structure, has become an urgent technical problem to be solved.

[0005] To address the aforementioned problems, this utility model proposes a prefabricated safety fence specifically designed for slope protection at construction sites. This fence employs an innovative steel foundation system, which can be pre-embedded in the structure during the concrete pouring stage, achieving integrated design of the fence and slope protection, significantly improving construction efficiency and fence stability. If the concrete structure has already been poured, precisely excavated holes of specific dimensions (e.g., 150*150*90mm) are used to embed the steel foundation with pre-embedded bolt holes and a bottom sealing plate into the holes, followed by grouting with higher-grade concrete to ensure a seamless connection between the fence foundation and the existing structure, further enhancing the fence's stability and safety. This design not only simplifies the installation process and reduces construction costs but also aligns with the concepts of green building and sustainable development, providing a more efficient, safe, and environmentally friendly safety protection solution for slope protection at construction sites.

Based on the following description and claims, the advantages and features of this utility model will become clearer. It should be noted that the accompanying drawings are all in a highly simplified form and are not to scale, intended only to facilitate and clearly illustrate the embodiments of this utility model.

[0024] Please refer to Figures 1 and 2. As shown in Figures 1 and 2, the prefabricated safety fence for construction site slope protection includes: a prefabricated safety fence main frame system, a lateral connection system, a base support system, and a steel foundation system; wherein, the prefabricated safety fence main frame system includes: corner vertical steel pipes (101), upper horizontal steel pipes (100), lower horizontal steel pipes (102), several intermediate vertical steel pipes (124), and support steel pipes (107).

The several intermediate vertical steel pipes (124) are welded to the upper horizontal steel pipes (100) and the lower horizontal steel pipes (102). The steel pipes of the safety fence frame system are coated with a layer of anti-rust paint (1).

[0025] The lateral connection system includes an inverted 7-shaped connecting rod (103) and a hollow sleeve (104). The inverted 7-shaped connecting rod (103) is welded to one side of the corner vertical steel pipe (101), and the hollow sleeve (104) is welded to one side of the corner vertical steel pipe (101).

[0026] The base support system includes: support steel pipes (107) arranged in a cross shape, and the support steel pipes are welded together in a cross shape.

[0027] The steel foundation system includes: a square steel plate (111) and a pre-embedded bolt hole plate with a bottom plate and a sealing plate (112). The square steel plate (111) is drilled with holes corresponding to the positions of the four pre-embedded bolt holes with a bottom plate and a sealing plate (112). After drilling, the square steel plate (111) is internally threaded on the inner wall of the four holes. After processing, the square steel plate (111) is welded to the pre-embedded bolt hole plate with a bottom plate and a sealing plate (112).

[0028] The base support system is located at the center of the steel foundation system, and the two are welded together to form an integrated composite foundation; the corner vertical steel pipes (101) of the prefabricated safety fence main frame system are welded to the supporting steel pipes (107) of the composite foundation, and the welded structure meets the verticality and horizontality standard requirements.

[0029] Please refer to Figure 3 again. Figure 3 is a detailed view of the nodes in Figure 2. Specifically, the connection between the base support system and the steel foundation system is clearer.

[0030] Please refer to Figures 4 and 5 again. The component system includes: a manual wrench (3) and hex bolts (2). The hex bolts (2) are respectively aligned with the bolt holes of the four pre-embedded bolt holes on the square steel plate (111) and the bottom plate sealing plate (112). The manual wrench (3) is tightened to form the assembled safety enclosure system.

[0031] In this embodiment, the steel plate (111) is preferably an ordinary smooth steel plate, which is convenient to operate and economical in cost as a steel base.

[0032] Understandably, the number of the aforementioned intermediate vertical steel pipes is selected according to the actual working conditions. That is, the prefabricated safety fence is assembled according to the actual working conditions, which is highly practical and meets the needs of various working conditions.

[0033] Specifically, based on the four pre-embedded bolt holes on the square steel plate (111) with the bottom plate sealing plate (112), first align the hexagonal bolts (2) with the bolt holes on the four pre-embedded bolt holes on the square steel plate (111) with the bottom plate sealing plate (112), and tighten the hexagonal bolts (2) with a manual wrench (3) to form a prefabricated safety enclosure system, so as to achieve the purpose of assembly and facilitate installation and disassembly.

[0035] In summary, the prefabricated safety fence for construction site slope protection provided by this utility model has the following significant advantages over traditional fences:

[0036] (1) High efficiency and shortened construction period: The prefabricated steel foundation system for safety enclosures offers two flexible installation methods. For newly built sites, it can be pre-embedded during concrete pouring. For sites with already poured concrete, the foundation can be fixed by simple excavation, embedding of sealing plates, and grouting. With the help of a manual wrench, the tightening and loosening of hexagonal bolts can be easily achieved without the need for complex large equipment. The entire installation process is simple and quick, significantly reducing construction time and helping construction projects to proceed efficiently. It is especially suitable for projects with strict requirements on the construction period. (2) Stable structure and safety guarantee: The steel foundation system is closely integrated with the concrete structure. The pre-embedded bolt holes with bottom sealing plates are scientifically and reasonably designed. Through high-grade concrete grouting, the connection strength between the foundation and the surrounding structure is greatly enhanced. This stable connection method ensures that the enclosure can remain stable under various harsh environments (such as strong winds, rainstorms, earthquakes, etc.), effectively preventing safety accidents such as enclosure tilting and displacement, and providing reliable safety guarantees for construction personnel and the surrounding environment. (3) Cost saving and economical and practical: The prefabricated design realizes the standardization and large-scale production of enclosure components, reducing production costs. During installation, no complex foundation construction or large equipment investment is required, reducing labor and machinery costs. At the same time, the fence can be repeatedly disassembled and reused, and can be quickly disassembled and assembled when transferred between different construction projects or construction sites, improving resource utilization, reducing overall usage costs, and saving a lot of money for construction companies. (4) Simple operation and reduced skill requirements: The design of tightening and loosening hexagonal bolts with manual wrenches makes the installation and disassembly of the fence simple and easy to understand. No professional technicians are required, and ordinary construction workers can operate it after simple training. This not only reduces the skill level requirements of construction workers, but also reduces installation quality problems caused by improper operation, and improves the accuracy and reliability of construction. (5) Environmental protection and energy saving, green construction: The prefabricated safety fence is made of recyclable materials and can be recycled and reused after dismantling, reducing the generation of construction waste and conforming to the concept of green building and sustainable development. At the same time, no large amount of energy is used or a large amount of dust, noise and other pollution is generated during the construction process, reducing the impact on the surrounding environment and achieving the goal of environmental protection and energy saving green construction. (6) High adaptability and wide application: This prefabricated safety fence steel foundation system can adapt to the slope protection needs of different types of construction sites. Whether it is urban construction, road construction, bridge construction or mining engineering, it can provide reliable protection solutions. Its flexible installation method and robust structural design enable it to play a good role in various complex terrains and construction conditions, and has a wide range of application prospects.

[0037] Obviously, based on the technical principles covered by this utility model, those skilled in the art can make reasonable adjustments and optimizations to the utility model without violating its core essence and application boundaries. If such adjusted and optimized technical solutions fall within the technical scope and equivalent technical features defined by the claims of this utility model, then such adjusted and optimized solutions should also be included in the protection scope of this utility model.
