Description

Technical Field

[0001] The utility model relates to a protective fence, in particular to a platform protective fence. Background Art

[0002] In today's construction engineering field, the foundation is the key cornerstone that bears the weight of the superstructure. The stability and safety of its structure are crucial to ensure the long-term reliable operation of the entire project. Although traditional foundation protection measures can provide basic safety guarantees in the early stages of construction, these measures often focus on the short construction period and fail to fully consider the complex challenges and durability requirements faced by the foundation protection system during long-term service. With the rapid development of the construction industry, especially for high-rise buildings, large bridge projects and key infrastructure projects, the stability of the foundation is directly related to the success of the entire project. Any minor protection omissions may trigger a chain reaction, threatening public safety and structural integrity.

[0003] The pier protection fences commonly used in the market are mostly based on a simplified enclosure design concept. Although they can temporarily isolate external interference and prevent accidental falls, their performance in terms of structural stability and environmental adaptability is insufficient. Especially in the face of extreme climatic conditions (such as typhoons and earthquakes), these protection facilities expose obvious fragility and are prone to displacement, deformation, and even collapse, thus becoming potential safety hazards.

[0004] Furthermore, the existing construction technology of protective fences, especially the connection method between components, mostly uses traditional bolt fastening or welding technology. Although it is convenient and efficient in the initial installation, these connection points often become weak links in the structure over time. Metal fatigue, corrosion, repeated load changes, and occasional severe external forces can cause the connection to gradually loosen or damage, thereby affecting the structural stability and durability of the entire protection system. Therefore, how to innovate the protective fence of the platform and improve its adaptability under complex working conditions and long-term service reliability has become a technical problem that needs to be solved in the current field of building protection. Utility Model Content

[0005] The purpose of the utility model is to address the above-mentioned problems and provide a platform protection fence that can ensure long-term stability and durability, effectively cope with complex environmental challenges, and improve the level of safety protection.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a pedestal protective fence, comprising a plurality of fence monomers, wherein the plurality of fence monomers are connected end to end in sequence to form a protective space arranged on the pedestal, and also comprising a pull rod assembly, wherein adjacent fence monomers are connected by a connecting mechanism, and an angle steel for fitting with the surface of the pedestal is fixed at the lower end of each of the fence monomers, and the pull rod assembly is horizontally connected between at least one of the relatively arranged angle steels.

[0008] Preferably, bending portions are respectively provided on both sides of the first fence monomer, and the connecting mechanism is provided between the bending portion and the second fence monomer.

[0009] Preferably, the connecting mechanism includes at least two groups of connecting units, each group of connecting units includes a first flange, a second flange, a locking bolt and a locking nut, the first flange is fixed on the side wall of the bending portion, the second flange is fixed on the side wall of the second fence monomer, the locking bolt is connected to the first flange, and one end of the locking bolt passes through the first flange and the second flange in sequence and is threadedly connected to the locking nut.

[0010] Preferably, a protective gasket is provided between the angle steel and the bearing platform.

[0011] Preferably, the pull rod assembly includes at least one group of pull rod units, each group of the pull rod units includes a tension rod, a reinforcing plate is vertically fixed on the angle steel, base plates are respectively fixed at both ends of the pull rod, the base plates are fitted with the corresponding reinforcing plates, and a locking assembly is connected between the base plates and the corresponding reinforcing plates.

[0012] Preferably, the locking assembly includes two limiting bolts and two limiting nuts, the two limiting bolts are horizontally spaced and connected between the base plate and the reinforcing plate, and the two limiting nuts are respectively screwed on the corresponding limiting bolts.

[0013] Preferably, the fence unit includes multiple vertical poles, multiple horizontal poles and a protective net, the multiple vertical poles are evenly spaced, the multiple horizontal poles are spaced up and down between the multiple vertical poles, and the protective net is covered and installed between the multiple vertical poles and the multiple horizontal poles.

[0014] Preferably, a protective plate is installed at the bottom of each fence monomer, and a warning sign is arranged on the protective plate, and a safety door is movably connected to one of the fence monomers.

[0015] Preferably, two lifting ears are fixed to the upper end of each fence monomer, and the two lifting ears are symmetrically arranged along the longitudinal center line of the fence monomer.

[0016] Compared with the prior art, the advantages of the utility model are: the protective fence is composed of a plurality of fence monomers, which are connected end to end in sequence and connected by a connecting mechanism to form a continuous protective space covering the base. The key is that the lower end of each fence monomer is equipped with an angle steel for tightly fitting with the base surface, which increases the connection stability between the overall structure and the base.

[0017] In addition, the device introduces a tie rod assembly that spans and horizontally connects between the relatively arranged angle steels. The setting of this tie rod assembly not only enhances the lateral connection strength between the fence units, but also balances the force on the fence, improving the resistance and stability of the entire system in the face of extreme weather such as typhoons and earthquakes. This rigid connection between the tie rod assembly and the fence unit effectively disperses the impact load caused by accidental external forces and reduces the risk of structural defects caused by fatigue, corrosion or relaxation of the connection points. Not only that, this device takes into account the needs of long-term service. The use of angle steel and tie rod assemblies improves the resistance of the entire protection system to environmental corrosion and ensures that the fence can withstand long-term environmental erosion without compromising its structural stability. This device simplifies the connection method between traditional protective fence components that relies on bolt fastening or welding, and provides a more stable, reliable and easy-to-maintain solution, thereby greatly improving the safety protection level of the platform protection fence and effectively responding to complex environmental challenges.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1: As shown in the figure, a foundation protective fence includes a plurality of fence monomers 1, which are connected end to end in sequence to form a protective space 2 arranged on the foundation, and also includes a tie rod assembly 3. Adjacent fence monomers 1 are connected by a connecting mechanism 4. An angle steel 5 for fitting with the surface of the foundation is fixed at the lower end of each fence monomer 1, and the tie rod assembly 3 is horizontally connected between at least one relatively arranged angle steel 5.

[0028] Embodiment 2: As shown in the figure, the difference from Embodiment 1 is that the fence monomer 1 is divided into a first fence monomer 6 and a second fence monomer 7. The number of the first fence monomers 6 is two, and the number of the second fence monomers 7 is two. The two first fence monomers 6 are relatively distributed, and the two second fence monomers 7 are relatively distributed. The connecting mechanism 4 is arranged between the first fence monomer 6 and the second fence monomer 7.

[0029] In the design of the pedestal protection fence of the present invention, the fence monomers 1 are divided into two types, namely, the first fence monomers 6 and the second fence monomers 7, two of each, forming a structural symmetry and functional complementarity. The two first fence monomers 6 and the two second fence monomers 7 are interconnected by the set connection mechanism 4. This configuration not only enhances the stability of the entire protection system, but also improves the adaptability and flexibility. The advantages are, firstly, through the relatively distributed setting of the first fence monomers 6 and the second fence monomers 7, a more stable support frame is achieved, providing all-round protection for the pedestal on all four sides. This four-way layout is conducive to evenly dispersing external impact force and avoiding excessive pressure on one side. And reduce the overall protection effect. Secondly, the design of the connecting mechanism 4 strengthens the stable connection between the first fence monomer 6 and the second fence monomer 7, which not only improves the structural integrity of the fence, but also facilitates installation and disassembly. When faced with special situations requiring adjustments or daily maintenance, this design can respond quickly, reducing working hours and costs. In addition, the design subdivides the fence units so that each monomer can be flexibly used according to the actual situation on site, providing higher applicability and better environmental adaptability than a single large fence monomer. Under extreme climatic conditions, this flexibly configured fence monomer and its connection structure can more effectively resist the risks of displacement, deformation and even collapse, thereby ensuring the safety of the structure and its users.

[0030] In this embodiment, bending portions 8 are respectively provided on both sides of the first fence monomer 6 , and the connecting mechanism 4 is provided between the bending portion 8 and the second fence monomer 7 .

[0031] Bending portions 8 are designed on both sides of the first fence monomer 6. This structural feature allows the connecting mechanism 4 to be arranged between the bending portion 8 of the first fence monomer 6 and the second fence monomer 7, creating a more stable and strong connection method. The existence of the bending portion 8 increases the three-dimensionality and bending strength of the fence monomer, making the overall structure of the fence more solid and durable. Through the connecting mechanism 4 between the bending portion 8 and the second fence monomer 7, a close connection between two different types of fence monomers can be achieved. This combination method is not only limited to connections on a plane, but also adds multi-point fixation in the vertical and horizontal directions, dispersing the force caused by external impacts such as wind pressure or collision, and reducing the possibility of damage to the fence due to force in a single direction. In addition, the design of the bending portion 8 also increases the area of ​​the fence monomer, which not only provides a larger contact area for the connection, thereby improving the overall stability of the fence, but also can enhance the fence's shielding ability to the external environment, and more effectively protect the platform and its staff from external interference.

[0032] In actual construction and use, the setting of the bending portion 8 also facilitates the installation and disassembly of the fence, because it provides more assembly points and clearer positioning instructions, thereby speeding up the work, reducing the construction difficulty, and improving the overall construction efficiency.

[0033] Embodiment three: As shown in the figure, different from embodiment two, the connecting mechanism 4 includes at least two groups of connecting units 9, each group of connecting units 9 includes a first flange 10, a second flange 11, a locking bolt 12 and a locking nut 13, the first flange 10 is fixed on the side wall of the bending portion 8, the second flange 11 is fixed on the side wall of the second fence monomer 7, the locking bolt 12 is connected to the first flange 10, and one end of the locking bolt 12 passes through the first flange 10 and the second flange 11 in sequence and is screwed to the locking nut 13.

[0034] In the cap protection fence of the utility model, the design of the connection mechanism 4 adopts at least two groups of connection units 9, which greatly enhances the stability and reliability between the fence monomers. Each group of connection units 9 is composed of a first flange 10, a second flange 11, a locking bolt 12 and a locking nut 13, wherein the first flange 10 is fixed on the side wall of the bending portion 8 of the first fence monomer 6, and the second flange 11 is fixed on the side wall of the second fence monomer 7. Through the synergistic effect of the locking bolt 12 and the locking nut 13, the first flange 10 and the second flange 11 are tightly connected, thereby stably locking the two fence monomers together. This design not only ensures the long-term stability of the cap protection fence in a complex environment, but also takes into account the convenience of installation and daily maintenance, and provides effective guarantee for providing reliable and lasting safety protection. Specifically, the advantages are:

[0035] 1. Enhanced structural stability: The combination of flanges and bolts forms a solid structural interface, effectively enhancing the connection strength between fence monomers 1. This structure can better maintain stability when subjected to external impact forces (such as strong winds, collisions, etc.), reducing the risk of fence collapse due to loose connections;

[0036] 2. Easy installation and maintenance: The flange and bolt connection method makes installation easier and faster. When maintenance or replacement of the fence unit is required, just loosen the locking nut 13 to easily disassemble it, which significantly improves the maintenance efficiency and practicality of the fence system;

[0037] 3. Adjustability: The configuration of the locking bolt 12 and the nut provides a certain adjustment space, so that the position of the fence can be fine-tuned according to the actual situation during installation to adapt to the installation environment of different platforms, ensuring the installation quality and neat appearance of the fence;

[0038] 4. Durability: The connection method of flange with bolts and nuts can use corrosion-resistant and high-strength materials to ensure durability and oxidation resistance in long-term use and adapt to various complex and harsh environmental conditions.

[0039] In this embodiment, a protective gasket 14 is provided between the angle steel 5 and the support platform.

[0040] The protective gasket 14 has multiple functions: first, it acts as a buffer, reducing the friction and stress concentration caused by the direct contact between the fence unit 1 and the base, and can significantly extend the service life of the angle steel 5 itself and the base surface; secondly, the gasket can absorb a certain amount of vibration and impact force, improve the stability of the fence, especially under external impact or extreme weather conditions, and can provide additional protection for the fence and the base.

[0041] The material of the protective gasket 14 is usually wear-resistant and corrosion-resistant material, such as rubber, nylon or sealing foam, which provides a natural barrier layer to further prevent the angle steel 5 from rusting and the base from damage due to environmental factors such as moisture and chemicals. Moreover, this layer of isolation of the gasket not only helps to reduce the damage caused by severe weather conditions, but also provides a stable foundation for the positioning of the angle steel 5, especially during the installation process, it can prevent the angle steel 5 from scratching the base surface due to movement, thereby ensuring the construction quality.

[0042] In this embodiment, the pull rod assembly 3 includes at least one group of pull rod units 15, each group of pull rod units 15 includes a tension rod 16, a reinforcing plate 17 is vertically fixed on the angle steel 5, and base plates 18 are fixed at both ends of the pull rod respectively. The base plates 18 are fitted with the corresponding reinforcing plates 17, and a locking assembly 19 is connected between the base plates 18 and the corresponding reinforcing plates 17.

[0043] The tie rod assembly 3 design of the pedestal protective fence provides additional lateral stability support, which is achieved through at least one group of tie rod units 15, wherein each group of tie rod units 15 includes a tension rod 16. These tension rods 16 help each fence unit to maintain stability in the horizontal direction through their own tensile properties. In order to further improve the firmness of the connection, a reinforcement plate 17 is vertically fixed on the angle steel 5, and base plates 18 are respectively fixed at both ends of the tie rod. These base plates 18 are fitted with corresponding reinforcement plates 17, and the base plates 18 and reinforcement plates 17 are connected by a locking assembly 19, which increases the overall rigidity of the structure and the seismic resistance of the protective fence.

[0044] In this embodiment, the locking assembly 19 includes two limiting bolts 20 and two limiting nuts 21 . The two limiting bolts 20 are horizontally spaced and connected between the base plate 18 and the reinforcing plate 17 . The two limiting nuts 21 are respectively screwed on the corresponding limiting bolts 20 .

[0045] The design of the locking assembly 19 significantly improves the structural stability and adjustment flexibility of the fence. The locking assembly 19 is composed of two limit bolts 20 and two corresponding limit nuts 21. These limit bolts 20 are horizontally spaced and connected between the base plate 18 and the reinforcement plate 17, and the limit nuts 21 are screwed on the corresponding limit bolts 20. The advantage of this arrangement is that it not only ensures a tight and stable connection between the base plate 18 and the reinforcement plate 17, but also allows the tension between the pull rod unit 15 and the fence monomer to be fine-tuned by adjusting the position of the limit nut 21 on the bolt, so as to adapt to different installation and use conditions. At the same time, the design provides a safe and reliable mechanical locking means, which can maintain the stability of the connection structure even under long-term load or extreme weather conditions, and prevent safety hazards caused by loose components. In addition, the use of limit bolts 20 and nuts greatly simplifies the installation and maintenance process of the fence. When adjustment or maintenance is required, the staff can quickly and easily operate the bolts and nuts without using professional tools or disassembling the entire structure, thereby enhancing the convenience and economy of the entire fence system.

[0046] Embodiment 4: As shown in the figure, different from Embodiment 3, each fence unit 1 includes multiple vertical poles 22, multiple horizontal poles 23 and a protective net 24, the multiple vertical poles 22 are evenly distributed, the multiple horizontal poles 23 are distributed between the multiple vertical poles 22 at intervals, and the protective net 24 is covered and installed between the multiple vertical poles 22 and the multiple horizontal poles 23.

[0047] The fence unit 1 is composed of a plurality of evenly distributed vertical poles 22, horizontal poles 23 arranged at intervals up and down, and a protective net 24 covering the entire structure. The vertical poles 22 provide vertical support for the entire protective fence, while the horizontal poles 23 enhance the connection stability between the vertical poles 22 in the horizontal direction, making the entire fence more solid and wind-resistant. The protective net 24 is installed on the inner side of the vertical poles 22 and the horizontal poles 23. It not only prevents debris and small tools from falling into the base area, but also prevents construction workers from accidentally falling, thereby improving on-site safety. The use of the protective net 24 also makes it easier for workers to maintain external vision while working. In addition, this mesh structure can effectively reduce wind resistance when encountering strong winds and other climatic conditions, thereby reducing the risk of collapse faced by the fence.

[0048] In practical applications, the advantages of this fence structure are quick and easy installation and simple maintenance. The standardized size design of the vertical poles 22 and the horizontal poles 23 allows for quick assembly and disassembly, and the length and height of the fence can be flexibly adjusted according to engineering needs. The protective net 24, as a lightweight material, will not bring excessive burden to the vertical poles 22 and the horizontal poles 23, and therefore will not affect the stability of the overall structure.

[0049] In this embodiment, a protective plate 25 is installed at the bottom of each fence monomer 1, and a warning sign is provided on the protective plate 25. A safety door 27 is movably connected to one of the fence monomers 1.

[0050] In the foundation protection fence of the utility model, a protective plate 25 is added to the lower part of each fence unit, and warning signs are set on these protective plates 25. This design not only enhances the safety protection function of the fence, but also plays an obvious warning role. The protective plate 25 is located at the bottom of the fence, providing an additional physical barrier for the fence. This structure can effectively prevent debris inside and outside the construction site from entering the construction area, and also increases the structural stability of the fence, so that it can better resist collisions and external impact forces.

[0051] The warning signs set on the protective plate 25 further improve the effect of safety protection. These warning signs can clearly notify workers and passers-by to pay attention to the existence of the construction area, thereby prompting people to take extra caution when approaching or entering the construction area, effectively reducing the occurrence of safety accidents. The color of the warning signs usually adopts high-visibility colors, such as bright yellow or bright red, which contrasts with the black font to ensure that they can be clearly seen even in dim light or poor visibility.

[0052] In addition, the provision of the protective plate 25 not only enhances the protective function of the fence, but also adds a uniform visual effect to the appearance of the fence, making the construction site more standardized and professional. Since the protective plate 25 is easy to install and replace, the construction unit can adjust the warning signs according to the project's specific safety requirements and warning information needs, providing a flexible safety management tool. The provision of the safety door 27 facilitates the entry and exit of construction personnel.

[0053] In this embodiment, two lifting ears 26 are fixed to the upper end of each fence monomer 1 , and the two lifting ears 26 are symmetrically arranged along the longitudinal center line of the fence monomer 1 .

[0054] The advantage of this design is that a single fence unit 1 can be carried conveniently and safely. The symmetrically placed lifting ears 26 can maintain balance when the fence unit 1 is lifted, avoiding swinging or flipping of the fence unit during transportation due to uneven force distribution, thereby reducing the risk of accidents that may occur during operation.

[0055] The use of the lifting lugs 26 provides great convenience for rapid assembly and disassembly, especially when the construction site layout needs to be frequently changed or operations are performed in a limited space, which can significantly improve work efficiency. A crane or other lifting equipment can directly use these lifting lugs 26 to quickly and safely position the fence unit and move it to the desired position, or move it out of the construction area when not needed, thereby meeting the needs of the construction site for efficient and safe operations.

[0056] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
