Description

Technical Field

[0002] In construction projects, bridge building, high-altitude operations, and foundation pit excavation, edge protection railings are widely used as a fundamental safety measure to ensure the personal safety of workers. Their main functions include isolating dangerous areas, warning workers, preventing falls from heights, and improving the organization and safety of the work area. Construction sites often have variable spatial environments and complex site conditions, placing high demands on the mobility, ease of assembly, and installation efficiency of guardrails. Therefore, guardrail systems with characteristics such as rapid erection, high stability, and convenient maintenance have become an important guarantee for improving on-site management efficiency and construction safety levels.

[0003] Currently, the edge protection railing structures widely used on construction sites are mainly steel pipe fastener type or welded fixed structure. Traditional steel pipe fastener type railings are usually constructed using steel pipes with a large diameter.

[0004] However, the need for manual painting of yellow-black or red-white warning colors before construction increases preparation time and labor costs. Structurally, traditional steel pipes are mostly of fixed length; if short openings or irregular edges are encountered, they must be cut and customized, resulting in material waste. Furthermore, replacement and maintenance rely on professional personnel and tools, leading to inefficiency and creating safety blind spots. These problems are quite common in practical use, gradually revealing the shortcomings of traditional guardrails in terms of construction flexibility, structural versatility, ease of maintenance, and environmental adaptability. Therefore, there is an urgent need to provide a more rationally designed, easier-to-assemble and disassemble, more modular, easier-to-maintain, and standardized construction-compliant socket-type guardrail structure to solve these problems.

[0040] See Figure 1 A preferred embodiment of this application provides a socket-type guardrail, which is composed of several splicing modules 10, such as... Figure 3 As shown, the splicing module 10 includes two horizontal bars 110, four connectors 130, four snap-fit ​​components 140, and two socket bases 150. The two horizontal bars 110 are arranged in parallel. Each vertical bar 120 is disposed between two horizontal bars 110, and both ends of each vertical bar 120 are connected to the two horizontal bars 110 respectively. The first and last vertical bars 120 located in the extension direction of the horizontal bars 110 are defined as the first splicing bar 121 and the second splicing bar 122, respectively. Two of the four connectors 130 are disposed at the same end of the two horizontal bars 110, and the remaining two connectors 130 are disposed at the same end of the first splicing bar 121 and the second splicing bar 122. The snap-fit ​​assembly 140 is detachably connected to the receiving connector 130, with two snap-fit ​​assemblies 140 located at the other ends of the two horizontal bars 110, and the remaining two snap-fit ​​assemblies 140 located at the other ends of the first splicing bar 121 and the second splicing bar 122. The two socket bases 150 are detachably connected to the snap-fit ​​assemblies 140 on the first splicing bar 121 and the second splicing bar 122, respectively. Furthermore, after the splicing of the socket-type guardrail is completed, the snap-fit ​​components 140 at the ends of the two horizontal bars 110 in the splicing module 10 are detachably connected to the receiving joints 130 at the ends of the two horizontal bars 110 adjacent in the extension direction of the horizontal bars 110. The snap-fit ​​components 140 at the ends of the first splicing bar 121 and the second splicing bar 122 in the splicing module 10 are respectively detachably connected to the receiving joints 130 at the ends of the first splicing bar 121 and the second splicing bar 122 adjacent in the extension direction of the vertical bar 120.

[0041] This embodiment provides a socket-type guardrail composed of multiple interlocking standardized splicing modules 10. Each splicing module 10 has a consistent structure and high interchangeability, making it suitable for construction scenarios requiring rapid assembly and efficient maintenance. Each splicing module 10 includes:

[0042] The two parallel horizontal bars 110 are preferably made of galvanized steel pipe, aluminum alloy pipe or other high-strength corrosion-resistant materials, and serve to support and connect the vertical bars 120. Further, in one embodiment, the horizontal bars 110, when viewed in cross-section, have a length of 50mm, a width of 50mm, and a thickness of 2.5mm.

[0043] Several vertical bars 120 are vertically arranged between two horizontal bars 110, forming the main protective surface of the guardrail. The ends of each vertical bar 120 are welded or mechanically fixed to the upper and lower horizontal bars 110, respectively. The first splicing bar 121 and the second splicing bar 122 are vertical bars 120 respectively located at the beginning and end of the horizontal direction of the splicing module 10, and can form a mating interface during horizontal splicing through structural definition. Further, in one embodiment, the vertical bar 120 is a square steel tube, and its cross-section shows a length of 50mm, a width of 50mm, and a thickness of 1.5mm.

[0044] Two of the four connectors 130 are located at the same end of the horizontal bar 110, and the other two are located at the same end of the first splicing bar 121 and the second splicing bar 122. The connectors 130 are provided with an insertion guide structure on the outside.

[0045] Four snap-fit ​​components 140 are provided one-to-one with the connectors 130 at the other end of the horizontal bar 110 and the splicing bar, for detachable connection with the connectors 130.

[0046] Two socket bases 150 are respectively connected to the snap-fit ​​components 140 of the first splicing column 121 and the second splicing column 122. The bottom of the base is provided with expansion bolt holes or pins for fixing to the ground to ensure overall stability. Furthermore, in one embodiment, one end of the socket base 150 is provided with a mounting seat. The side of the mounting seat opposite to the socket base 150 is flat, and the mounting seat is provided with fixing holes.

[0047] The above-described combination of structures ensures stable assembly and rapid disassembly of the splicing module 10 in both the horizontal and vertical directions, achieving structural standardization and rapid deployment.

[0048] In practical use, firstly, multiple socket bases 150 are installed on the floor or foundation surface, with the positions preset according to the construction drawings. Then, the splicing modules 10 are assembled along a predetermined path, allowing the interlocking components 140 between modules to connect with the socket joints 130 of adjacent modules. Next, during connection, the interlocking components 140 are inserted into the socket joints 130. Furthermore, the above connection method is used between horizontal bars 110, between first splicing bars 121, and between second splicing bars 122 to ensure continuous splicing of the overall frame in both horizontal and vertical directions. Finally, the interlocking components 140 at the lower ends of the first and second splicing bars 121 are inserted into the socket bases 150 and fixed, completing the installation of the overall guardrail structure. This structure allows for rapid assembly by non-professionals without welding or special tools, and is easy to disassemble and replace.

[0049] This embodiment adopts a standardized splicing module 10 design, which is compact in structure and flexible in assembly. It can be quickly connected in both horizontal and vertical directions, significantly improving construction efficiency. The snap-fit ​​component 140 and the socket joint 130 are detachably connected, requiring no welding or special tools, which is convenient for non-professionals to maintain and replace, reducing operation and maintenance costs. The splicing fence and the base are firmly connected by a socket method, which improves overall stability and reduces environmental pollution. At the same time, the fence surface has been uniformly sprayed at the factory, avoiding on-site painting work and meeting the requirements of green and environmentally friendly construction.

[0050] In some embodiments, such as Figure 2 As shown, the snap-fit ​​assembly 140 includes a connector 141, a positioning member 142, and an elastic member 143. The connector 141 has a through hole inside. The positioning member 142 includes an abutment end 1422 and a positioning end 1421. The positioning end 1421 is movably disposed in the through hole and extends to the outside of the connector 141. The elastic member 143 is compressed in the through hole and is connected to the abutment end 1422 of the positioning member 142, and applies elastic force to the abutment end 1422, causing the positioning end 1421 of the positioning member 142 to protrude from the surface of the connector 141. Both the socket base 150 and the socket connector 130 include a socket slot, which is adapted to the connector 141. The inner wall of the socket slot is provided with a snap-fit ​​groove, which is configured to engage with the positioning end 1421 of the positioning member 142 after the connector 141 is inserted into the socket slot.

[0051] Specifically:

[0052] The connector 141 is an integral housing structure, preferably made of corrosion-resistant metal or high-strength engineering plastic. One end has an insertable structure that mates with the socket base 150 or the socket 130. An axial through hole is provided inside the connector 141, providing installation space for the embedded positioning mechanism.

[0053] The positioning element 142 includes an integrally formed abutment end 1422 and a positioning end 1421. The positioning end 1421 is a slender columnar structure that passes through the through hole and extends from the outside of the connector 141 for mechanical limiting engagement with the external locking groove. The abutment end 1422 is located inside the through hole and is in direct contact with the elastic element 143.

[0054] The elastic element 143 is preferably a helical spring, which is compressed and disposed in the through hole, located between the abutment end 1422 and the inner wall of the plug 141. By continuously applying elastic force, the positioning end 1421 of the positioning element 142 is pushed out of the surface of the plug 141 to form an initial locking state.

[0055] Furthermore, both the socket base 150 and the socket connector 130 are provided with socket slots. These slots are adapted to the shape of the connector 141 and can be circular, square, or polygonal in cross-section. In addition, the inner wall of the connector is provided with a snap-fit ​​groove for limiting and locking with the positioning end 1421 of the connector 141.

[0056] The core of this snap-fit ​​structure lies in the insertion, ejection, and locking / disassembly process. When the connector 141 is inserted into the socket, the positioning element 142 on the connector 141 is compressed back into the connector 141 at the socket entrance. The insertion continues until the connector 141 is fully inserted, at which point the positioning end 1421 of the positioning element 142 automatically ejects under the elastic force of the elastic element 143. This positioning end 1421 fits precisely into the pre-set snap-fit ​​groove on the inner wall of the socket, forming an axial limit and lock to prevent the connector 141 from being pulled out. During disassembly, the snap-fit ​​state can be released by manually pressing back the positioning element 142 or by using a puller to push the positioning end 1421 inward, achieving rapid assembly and disassembly. This process requires no tools and does not rely on electric control devices. The structure is self-locking, safe, and reliable, making it ideal for construction environments with frequent on-site assembly and disassembly.

[0057] In this embodiment, due to the structural combination of the plug-in connector 141, the elastic positioning element 142, the socket and the snap-fit ​​groove, the plugging process does not require screws or welding, avoiding problems such as loose bolts and detached welds in traditional connection methods. After the plug-in connector 141 is inserted, the positioning element 142 automatically snaps into the snap-fit ​​groove in the socket under the action of the elastic element 143, achieving rapid locking, thereby greatly improving the assembly and disassembly efficiency of the guardrail module. The entire process does not require any tools, and non-professionals can complete the operation, significantly reducing the construction and maintenance threshold. At the same time, the snap-fit ​​component 140 can be reused multiple times, improving the turnover efficiency and economy of the guardrail system. In addition, the structure has good anti-loosening, anti-falling and vibration resistance performance, adapting to high-frequency loading and unloading and complex construction environments, ensuring the connection reliability and structural safety of the guardrail in long-term use.

[0058] Furthermore, to further improve the operational stability and positioning reliability of the positioning member 142 in the snap-fit ​​assembly 140, in some embodiments, a limiting groove is formed on the inner wall of the through hole along its own extension direction. A limiting member is provided on the side of the positioning member 142, and the limiting member is disposed within the limiting groove to restrict the movement range of the positioning end 1421. The elastic member 143 is a spring. The snap-fit ​​assembly 140 contains two positioning members 142, both of which are movably disposed within the through hole, with the positioning ends 1421 of the two positioning members 142 facing each other, and the positioning ends 1421 of the two positioning members 142 respectively abutting against the two ends of the spring.

[0059] The limiting groove provided on the inner wall of the through hole along its extension direction is preferably a groove structure along the length direction of the through hole, the depth of which is less than the radius of the through hole, and is integrally processed or injection molded with the inner wall of the through hole.

[0060] The positioning member 142 is provided with a limiting member on its side wall. The limiting member is a protrusion or a limiting slider structure. Its cross-section is slightly larger than that of the positioning member 142 body. By being inserted into the limiting groove, the positioning member 142 can only move linearly in a controlled manner along the axis of the through hole, thereby preventing it from rotating or jamming due to assembly deviation or uneven elasticity, and ensuring the smoothness of the positioning action and the locking accuracy.

[0061] The elastic element 143 is a helical compression spring, disposed in the through hole, providing axial elastic force. Specifically, the snap-fit ​​assembly 140 includes two positioning elements 142, which are symmetrically arranged along the central axis of the through hole, with their positioning ends 1421 facing each other, i.e., one to the left and one to the right, or one in front and one behind. A spring is disposed between the two positioning elements 142, abutting against the abutting ends 1422 of each element. The compression force pushes the two positioning elements 142 out of the through hole, forming a bidirectional self-locking structure.

[0062] When the structure is in operation, the two positioning members 142 move towards the two ends of the through hole under the action of the spring, and their respective positioning ends 1421 extend from the surface of the connector 141 and are respectively inserted into the slots on the inner wall of the corresponding connector (such as the socket or the snap-fit ​​groove), so as to realize the bidirectional locking position of the connector 141 and the external connector.

[0063] When the connector 141 is inserted into the external structure, the two positioning ends 1421 are pressed and retract synchronously into the through hole. After full insertion, the spring pushes the two positioning parts 142 to pop out automatically, thus achieving positioning. When disassembling, the two positioning ends 1421 can be pressed simultaneously from the outside to overcome the spring force and make them exit the slot, thus achieving quick unlocking and removal.

[0064] This structure ensures automatic completion of the insertion action and rapid response of the disassembly process, greatly improving the ease of operation and locking reliability of the snap-fit ​​assembly 140 in repetitive assembly environments.

[0065] In this embodiment, the limiting groove inside the through hole, in conjunction with the limiting element on the positioning element 142, ensures that the positioning element 142 moves only in the axial direction, preventing it from shaking or shifting, thereby improving the stability of the snap-fit ​​structure. The two positioning elements 142 are arranged opposite each other by springs, and after insertion, they are respectively snapped into the corresponding slots of the components, achieving bidirectional self-locking and effectively preventing one-sided detachment. This structure requires no tools for insertion and disassembly, making it convenient and efficient, suitable for quick installation and replacement by non-professionals. The elastic element 143 is set between the two positioning elements 142, ensuring uniform force distribution and sensitive response, further improving structural strength and service life. The overall structure is compact, highly adaptable, suitable for various connection scenarios, and possesses good versatility and scalability.

[0066] Furthermore, the snap-fit ​​grooves in both the connector 141 and the socket base 150 penetrate the inner wall of the socket, forming pressing holes on the surfaces of both the connector 141 and the socket base 150. The positioning end 1421 of the positioning member 142 is configured to embed into the snap-fit ​​groove after the connector 141 is inserted into the socket, and to protrude from the pressing hole, such that the positioning end 1421 of the positioning member 142 protrudes from the surfaces of the connector 141 and the socket base 150.

[0067] The snap-fit ​​grooves of the connector 141 and the socket base 150 penetrate their inner walls, forming visible and operable pressing ports on the corresponding surfaces. After the connector 141 is inserted into the socket slot, the positioning end 1421 of the positioning member 142 is embedded in the snap-fit ​​groove and pushed out from the pressing port, so that the outer part of the positioning end 1421 protrudes from the outer surface of the connector 141 or the socket base 150, making it easy for users to intuitively judge whether the positioning is complete. During disassembly, the snap-fit ​​state can be quickly released by pressing the exposed part, thereby simplifying the assembly confirmation process and improving disassembly efficiency. This structure takes into account both snap-fit ​​reliability and ease of operation, and is particularly suitable for rapid assembly and maintenance by non-professional construction personnel. It has significant safety, human-machine interaction friendliness and on-site adaptability.

[0068] In the plug-in structure of the aforementioned socket-type guardrail, to further enhance the plug-in firmness and anti-detachment safety, in some embodiments, both the socket joint 141 and the socket base 150 are provided with a first through groove. The socket joint 141 is provided with a second through groove, which is configured to align with the first through groove after the socket joint 141 is inserted into the socket. The socket-type guardrail also includes a pin 160, which is configured to pass through an assembly groove formed by the first through groove and the second through groove after the socket joint 141 is inserted into the socket.

[0069] The first through groove has a transverse through structure and can be a strip-shaped through hole or a round hole. It is set on both sides or the bottom of the insertion interface and penetrates the wall of the insertion structure.

[0070] The connector 141 is an insert, and its body also has a second through groove. This groove has the same structure as the first through groove, and after the connector 141 is inserted into the socket, the two can be aligned to form a continuous assembly channel. The width and position of the channel are precisely designed according to the structural dimensions.

[0071] To achieve reliable connection and locking, a pin 160 is installed on the basis of the channel structure. The pin 160 can be a solid cylindrical pin, cotter pin, positioning pin, or plug pin, etc. Its material can be stainless steel, aluminum alloy, or nylon-reinforced plastic, and it has a certain shear strength and rust prevention performance.

[0072] During installation, the operator inserts the connector 141 into the socket. Once inserted to the predetermined depth, the second through slot on the connector 141 aligns with the first through slot on the socket / base, forming a complete assembly channel. At this point, the pin 160 is inserted into this assembly channel, mechanically locking the connector structure and preventing the connector 141 from coming out axially. If the connector is subjected to external force and tends to pull out, the pin 160 provides shearing restraint, ensuring a safe and stable connection. For disassembly, the operator simply pulls out the pin 160 from the outside, allowing the connector 141 to be easily removed, completing the quick disassembly of the guardrail.

[0073] In this embodiment, the plug-in structure features an alignable through-slot and a mechanical limiting structure formed by the pin 160, effectively preventing accidental dislodgement of the plug-in components under stress or vibration, significantly improving the safety of the guardrail connection. The pin 160, as an independent component, is simple and quick to install and remove, requiring no special tools, making it suitable for rapid deployment on construction sites. Furthermore, the pin 160 structure is reusable, reducing the frequency of parts replacement and maintenance costs. The standardized design of the through-slot and pin 160 is applicable to various types of plug-in structures, enhancing the versatility and interchangeability between guardrail modules. The overall anti-dislodgement structure, as a safety redundancy measure, provides reliable protection for the guardrail system in complex environments, demonstrating significant potential for widespread application.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
