Description

Technical Field

[0001] This utility model belongs to the field of pile foundation engineering construction technology, and in particular, it is a portable edge protection device for pile foundation engineering. Background Technology

[0002] A pile foundation is a deep foundation consisting of piles and a pile cap (or simply pile cap) connecting the pile tops, or a single pile foundation connecting a column to the pile foundation. If the entire pile is embedded in the soil and the bottom of the pile cap is in contact with the soil, it is called a low-pile-cap pile foundation; if the upper part of the pile is exposed above the ground and the bottom of the pile cap is above the ground, it is called a high-pile-cap pile foundation. Building pile foundations are typically low-pile-cap pile foundations. Pile foundations are widely used in high-rise buildings. In modern construction engineering, especially pile foundation engineering, temporary protective facilities are usually set up around the construction site to ensure construction safety and protect on-site personnel from accidental injury.

[0003] In today's construction environment, with the acceleration of urbanization and the continuous expansion of construction projects, higher demands are placed on the safety management of construction sites. Especially in pile foundation construction, where deep pit operations are involved, the consequences of a safety accident are often unimaginable. Therefore, there is an urgent need for a protective device that can provide effective physical isolation while also allowing for convenient and quick repositioning. Utility Model Content

[0004] The purpose of this invention is to provide a portable edge protection device for pile foundation engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable edge protection device for pile foundation engineering, comprising:

[0006] The pile foundation protection barrier group is formed by enclosing a longitudinal barrier component, a detachable movable barrier component, and two transverse barrier components.

[0007] The pile foundation pit is excavated on the ground within the pile foundation protective fence group;

[0008] The auxiliary walking components are multiple, and several are equidistantly installed at the bottom of each of the longitudinal barrier components, transverse barrier components, and detachable movable barrier components.

[0009] The detachable movable barrier assembly is connected to one end of the two transverse barrier assemblies via a detachable component. Each of the auxiliary walking components includes a caster wheel and an elastic component located above the caster wheel. The elastic component is fixedly connected to the bottom frame of the longitudinal barrier assembly, the detachable movable barrier assembly, and the two transverse barrier assemblies. This allows the elastic component to support the longitudinal barrier assembly, the transverse barrier assembly, or the detachable movable barrier assembly without applying any additional pressure other than the weight of the longitudinal barrier assembly, the transverse barrier assembly, and the detachable movable barrier assembly itself, enabling workers to push and move it by hand, thus facilitating portable adjustment of position and transportation.

[0010] In a preferred embodiment of this scheme, the longitudinal barrier assembly, the transverse barrier assembly, or the detachable movable barrier assembly all include multiple support columns arranged at equal intervals and protective netting installed between two adjacent support columns.

[0011] In this preferred embodiment, each of the supporting columns is welded to a base at its bottom end, and the base is connected to the concrete base below by expansion bolts.

[0012] In this preferred embodiment, each of the protective netting components has an L-shaped connecting buckle plate welded to its outer walls on both sides. Each L-shaped connecting buckle plate has an inclined through-hole on its inner wall away from the protective netting component. Furthermore, each of the supporting columns has an identical insertion slot on its outer wall that aligns with the inclined through-hole of each L-shaped connecting buckle plate.

[0013] In this preferred embodiment, an inclined rod is inserted into the inclined opening of the L-connecting buckle plate, and the inclined rod extends into the insertion opening of the supporting column to lock and hang the protective netting.

[0014] In this preferred embodiment, one end of each inclined insert rod that is inserted into the socket of the support column is the recessed end, and the end of the inclined insert rod away from the recessed end is located outside the L-connecting buckle plate and is welded with a pull ring.

[0015] In a preferred embodiment, the top of the omnidirectional wheel has a fixed top plate, and the elastic component includes a connecting top plate arranged parallel above the fixed top plate, a spring installed between the fixed top plate and the connecting top plate, and four positioning rods welded to the top surface of the fixed top plate in a rectangular distribution.

[0016] In this preferred embodiment, the top of each positioning pole is longitudinally connected to the top plate and threaded with a locking nut. The top surface of the connecting top plate is welded to the bottom surface of the frame of the longitudinal barrier assembly, the transverse barrier assembly, and the detachable movable barrier assembly.

[0017] In this preferred embodiment, both the fixed top plate and the connecting top plate have positioning grooves at the midpoint of their opposite sides for installing spring components.

[0018] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0019] This portable edge protection device for pile foundation engineering utilizes a pile foundation protective barrier assembly designed with longitudinal, transverse, and detachable movable barrier components. This design allows for flexible assembly and installation to accommodate different pile foundation pit shapes at various construction sites, achieving a modular and standardized functional layout and enabling the rapid construction of a safety barrier. This modular structure not only improves adaptability but also reduces the site restrictions imposed by traditional welded or fixed guardrails. The design, with the pile foundation pit positioned within the ground of the protective barrier assembly, physically isolates the construction area from personnel activity areas. Combined with the height of the protective barrier assembly, this effectively prevents workers from accidentally entering dangerous areas during construction, thus ensuring safety and improving the level of safety management at the construction site.

[0020] The design, featuring auxiliary walking components evenly spaced at the bottom of each barrier assembly, enables the entire device to be mobile, allowing workers to move or relocate it without the need for transport tools. In particular, each auxiliary walking component includes casters and elastic parts. The elastic parts can support the weight of the barrier assembly itself without additional force, allowing the device to be moved with just a slight push or pull. This facilitates convenient handling and flexible placement, improving construction efficiency and reducing labor intensity.

[0021] The design of the detachable movable barrier assembly, which connects to two horizontal barrier assemblies via detachable parts, allows the device to quickly open a passage when temporary passage or inspection is needed, without having to completely dismantle the protective structure. This achieves the purpose of partial disassembly and flexible use, facilitating construction management and ensuring the continuity of operations. Attached Figure Description

Detailed Implementation

[0030] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0031] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0032] This embodiment provides, for example Figures 1 to 5 A portable edge protection device for pile foundation engineering is shown, comprising:

[0033] The pile foundation protection barrier group 1 is formed by a longitudinal barrier component 2, a detachable movable barrier component 4, and two transverse barrier components 3.

[0034] Pile foundation pit 7 is located on the ground within pile foundation protective barrier group 1;

[0035] The auxiliary walking component 8 has multiple components, and several are installed at equal intervals at the bottom of each longitudinal barrier assembly 2, transverse barrier assembly 3, and detachable movable barrier assembly 4.

[0036] The detachable movable barrier assembly 4 is connected to one end of the two transverse barrier assemblies 3 via detachable components. Each auxiliary walking component 8 includes a caster wheel 9 and an elastic component 10 located above the caster wheel 9. The elastic component 10 is fixedly connected to the bottom frame of the longitudinal barrier assembly 2, the detachable movable barrier assembly 4, and the two transverse barrier assemblies 3, so that the elastic component 10 can support the longitudinal barrier assembly 2 or the transverse barrier assembly 3 or the detachable movable barrier assembly 4 without applying additional pressure other than the weight of the longitudinal barrier assembly 2, the transverse barrier assembly 3, and the detachable movable barrier assembly 4, allowing workers to push it by hand, thus enabling portable adjustment of position and transportation. When it is necessary to install the pile foundation protective netting assembly 1, simply assemble the longitudinal netting component 2, the transverse netting component 3, and the detachable movable netting component 4. When it is necessary to disassemble the pile foundation protective netting assembly 1, first remove the detachable parts from the detachable movable netting component 4, then remove the detachable movable netting component 4, and then gradually disassemble the longitudinal netting component 2 and the transverse netting component 3. Workers can push the disassembled longitudinal netting component 2, transverse netting component 3, or detachable movable netting component 4 by hand, and achieve portable handling with the help of the elastic component 10 and the casters 9.

[0037] In this embodiment, the longitudinal barrier assembly 2, the transverse barrier assembly 3, or the detachable movable barrier assembly 4 all include multiple support columns 5 arranged at equal intervals and protective netting 6 installed between adjacent support columns 5. The detachable connection between the detachable movable barrier assembly 4 and the transverse barrier assembly 3 not only facilitates local passage or inspection but also creates a "guide opening" during disassembly, providing directional guidance and space for the orderly disassembly of other components, thereby improving disassembly and assembly efficiency and preventing misoperation.

[0038] In this embodiment, each supporting column 5 has a base welded to its bottom end, and the base is connected to the concrete base floor below by expansion bolts. When there is no need for transportation, the base of the supporting column 5 is firmly connected to the concrete base floor, thereby compressing the spring member 14. At the same time, the four positioning rods 15 extend upward to the top of the connecting top plate 12, pressing the compression spring member 14 between the fixed top plate 11 and the connecting top plate 12. When transportation is required, the expansion bolts connecting the concrete base floor are removed. At this time, the compression spring member 14 is released from pressure and supports the protective net frame under its own elastic reaction force.

[0039] In this embodiment, each protective netting 6 has an L-connecting buckle plate 17 welded to its outer walls on both sides. Each L-connecting buckle plate 17 has an inclined through-hole 18 on its inner wall away from the protective netting 6. Furthermore, each supporting column 5 has an identical insertion port on its outer wall that is aligned with the inclined through-hole 18 of each L-connecting buckle plate 17.

[0040] In this embodiment, an inclined rod 19 is inserted into the inclined opening 18 of the L connecting plate 17, and the inclined rod 19 extends into the insertion hole of the support column 5 to lock and hang the protective net 6.

[0041] In this embodiment, one end of each inclined insert 19 that is inserted into the socket of the support column 5 is a recessed end 20, and the end of the inclined insert 19 away from the recessed end 20 is located outside the L-connecting buckle plate 17 and is welded with a pull ring 21. Figure 5 As shown, the sunken end 20 is the lowest end. When the sunken end 20 is inserted into the socket of the support column 5, the top of the inclined rod 19 near the pull ring 21 serves to hang the L-connecting buckle 17 and the protective net 6, thus not only supporting the erection of the protective net 6, but also facilitating the quick installation and disassembly of the protective net 6. When it is necessary to disassemble the protective net 6, simply pull the pull ring 21 with your finger to quickly pull the inclined rod 19 out of the inclined opening 18 and the socket of the support column 5.

[0042] In this embodiment, the top of the caster wheel 9 has a fixed top plate 11, and the elastic component 10 includes a connecting top plate 12 arranged parallel above the fixed top plate 11, a spring member 14 installed between the fixed top plate 11 and the connecting top plate 12, and four positioning rods 15 welded to the top surface of the fixed top plate 11 in a rectangular distribution.

[0043] In this embodiment, the top of each positioning pole 15 is longitudinally connected to the top plate 12 and threaded with a locking nut 16. The top surface of the top plate 12 is welded to the bottom surface of the frame of the longitudinal barrier assembly 2, the transverse barrier assembly 3 and the detachable movable barrier assembly 4.

[0044] In this embodiment, positioning grooves 13 for installing spring components 14 are provided at the middle positions of opposite sides of the fixed top plate 11 and the connecting top plate 12.

[0045] Working principle

[0046] Before excavating the pile foundation pit 7, the technicians determined the location of the pile foundation according to the construction drawings and assessed the surrounding terrain and geological conditions to ensure that the ground where the protective device is installed has the bearing capacity. In accordance with the design requirements, the pile foundation pit 7 was excavated at the designated location to prepare for the subsequent cast-in-place pile construction.

[0047] When assembling the pile foundation protective netting assembly 1, transport two horizontal netting components 3, one vertical netting component 2, and one detachable movable netting component 4 to the vicinity of the pile foundation pit 7. According to the shape and size of the pile foundation pit 7, the above components are enclosed to form a rectangle or other closed area. A protective netting is set around the pile foundation pit 7. The detachable movable netting component 4 is connected and fixed to the horizontal netting components 3 on both sides using detachable parts to form a complete closed protective structure.

[0048] Each netting assembly has multiple support columns 5 inside. Protective netting 6 is installed between two adjacent support columns. The protective netting 6 is quickly hung on the support column 5 through L-connecting buckle plate 17 and inclined insert rod 19. The inclined insert rod 19 is inserted into the inclined opening 18 of L-connecting buckle plate 17 and extends into the insertion port of support column 5. After insertion, the sunken end 20 is locked in place, and the pull ring 21 is exposed for subsequent disassembly. The bottom of the support column 5 is welded with a base, which is fixed to the concrete base ground by expansion bolts to enhance the overall stability.

[0049] The auxiliary walking component 8 consists of casters 9 and elastic components 10, which are installed under the bottom frame of each netting assembly. The elastic components 10 can support the entire netting assembly without additional pressure, allowing workers to move the device with just a slight push.

[0050] After installation, the pile foundation protection netting group 1 forms a physical isolation barrier around the pile foundation pit 7 to prevent personnel from accidentally entering the dangerous area. The protective netting 6 has good visibility and safety, and plays a dual role of warning and blocking.

[0051] When disassembling the protective netting component 6, pull the pull ring 21 to remove the inclined insert 19 from the L-connecting buckle plate 17 and the support column 5. The protective netting component 6 can then be easily removed for cleaning, maintenance, or replacement. When disassembling the netting assembly, first disassemble the connecting piece between the detachable movable netting assembly 4 and the transverse netting assembly 3, and then disassemble the longitudinal netting assembly 2 and the transverse netting assembly 3 in sequence. All components can be pushed to the designated storage area via the auxiliary walking component 8, eliminating the need for multiple people to lift them. Utilizing the support provided by the elastic component 10 and the flexibility of the casters 9, a single person can push the netting assembly weighing tens of kilograms. The device is lightweight and structurally stable, making it suitable for frequent handling and repeated use.
