[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model provides, for example Figure 1-6 The illustrated pin-type quick-installation and quick-disassembly integrated fixed guardrail includes an end component 1 and a standard component 2. Two end components 1 and several standard components 2 are combined and spliced ​​to form a complete guardrail. The two end components 1 are located at the front end and the rear end of the entire guardrail, respectively, and several standard components 2 are placed between the two end components 1 at equal intervals. A column 3 is provided on the outer side of each of the two end parts 1. A connecting column 4 is provided between the end part 1 and the standard part 2. A connecting column 4 is also provided between every two standard parts 2. A connecting rod 9 is vertically inserted above each connecting column 4. Each standard part 2 has a first plug-in group 6 on one side and a second plug-in group 7 on the other side. The first plug-in group 6 and the second plug-in group 7 are at different heights. The inner side of the front end component 1 is provided with a first plug-in group 6, and the inner side of the tail end component 1 is provided with a second plug-in group 7.

[0020] In this embodiment, two end components 1 are located at the beginning and end of the guardrail, respectively. Their outer sides are provided with evenly distributed protrusions 11 and threaded holes for fixing to the posts 3 with bolts 31, ensuring the stability of the guardrail foundation. The inner first plug-in group 6 (front end) or second plug-in group 7 (tail end) matches the plug-in group of the standard component 2, serving a positioning and splicing function, ensuring the accuracy and integrity of the guardrail assembly, while flexibly adapting to the boundary requirements of different protection scenarios. The standard component 2 serves as the main splicing structure of the guardrail, with first plug-in group 6 and second plug-in group 7 on both sides. The vertically distributed plug design and precise height difference allow for rapid stacking and splicing of the standard components 2 without complex measurements and adjustments. This modular structure allows for the addition or reduction of quantities as needed, flexibly adjusting the guardrail length to meet the protection length requirements of different construction areas, reducing on-site processing steps, and improving installation efficiency. Furthermore, in the above technical solution, multiple evenly distributed protrusions 11 are fixedly installed on the outer side of both end components 1. Each protrusion 11 has a threaded hole on its outer surface. A column 3 is provided on the outer side of both end components 1. The outer side of the column 3 and the corresponding position of each protrusion 11 are connected and fixed by bolts 31.

[0021] Furthermore, in the above technical solution, both the first plug-in group 6 and the second plug-in group 7 are composed of two plug blocks distributed vertically on the same side of the standard part 2. The height difference between the first plug-in group 6 and the second plug-in group 7 is the thickness of one plug block. Multiple standard parts 2 are placed sequentially, and the corresponding plug blocks of the first plug-in group 6 and the plug blocks of the second plug-in group 7 are stacked and spliced ​​vertically.

[0022] In this embodiment, plug group 6 and plug group 7 consist of two plug blocks distributed vertically on the same side of standard component 2. The plug blocks are stacked and spliced ​​to achieve quick connection between standard components, replacing traditional bolt connections. This design makes the installation process more convenient, allowing for single-person operation, reducing labor and time costs. Furthermore, the tight fit of the plug blocks effectively prevents lateral displacement of components, ensuring the stability of the railing structure.

[0023] Furthermore, in the above technical solution, a horizontal through-type interface 42 is provided below the connecting post 4, and the plugs below the first plug group 6 and the second plug group 7 are stacked and inserted into the interface 42. A vertical through-type slot 41 is provided at the top of the connecting post 4, and the slot 41 is connected to the bottom of the interface 42.

[0024] Furthermore, in the above technical solution, the plug blocks of the first plug group 6 and the second plug group 7 are provided with through holes 8, the connecting rod 9 is vertically inserted into the slot 41 of the connecting post 4, and the upper and lower ends of the connecting rod 9 are respectively connected to the through holes 8 on the plug blocks of the first plug group 6 and the second plug group 7.

[0025] Furthermore, in the above technical solution, a limiting hook 43 is provided on the upper back of the connecting post 4. The longer end of the limiting hook 43 is threadedly connected to the connecting post 4. A locking ring 91 is movably installed on the top of the connecting rod 9. The lower end of the locking ring 91 is connected to the limiting hook 43.

[0026] In this embodiment, the post 3 serves as the core support of the guardrail. Through bolt connection with the outer protrusion 11 of the end component 1, it transfers the overall load of the guardrail to the ground foundation. Its robust material and stable fixing method enable the guardrail to withstand horizontal loads, effectively resisting external forces such as personnel collisions and wind, preventing the guardrail from tilting or deforming, and ensuring the safety of the construction site. The connecting post 4 is equipped with a horizontal through-type interface 42 and a vertical through-type slot 41, forming a three-dimensional locking structure. The interface 42 accommodates the insert blocks of the first plug group 6 and the second plug group 7 of the standard component 2, achieving lateral limiting. The slot 41, in conjunction with the connecting rod 9 penetrating the through hole 8 of the insert block, and combined with the hook limiting hook 43 and the locking ring 91, forms a vertical anti-detachment mechanism. This simplifies the connection operation, allowing for quick insertion and removal without additional tools, while enhancing the overall integrity and anti-loosening performance of the guardrail structure. The multiple locking design ensures a tight connection of components, significantly improving the overall stability and impact resistance of the guardrail. Furthermore, steel plates are welded to the bottom of both column 3 and connecting column 4, and the steel plates are connected and fixed to the ground by expansion bolts to ensure the stability of connecting column 4 and column 3.

[0027] Furthermore, in the above technical solution, both end component 1 and standard component 2 are frame structures. Protective nets 5 are embedded in the frames of both end component 1 and standard component 2. The protective nets 5 are fixed around the perimeter by welding steel plates. The steel plates at the upper and lower ends of the protective nets 5 are connected and fixed to end component 1 or standard component 2 by rivets.

[0028] In this embodiment, the protective netting is adapted to the frame structure of end component 1 and standard component 2, conforming to the overall modular design of the railing. During the manufacturing process, the protective netting 5 is directly fixed to end component 1 or standard component 2 using rivets before being shipped out, eliminating the need for additional adjustments or complex installation steps and effectively shortening the installation time at the construction site. During disassembly, the protective netting and frame are transferred as a whole, reducing the possibility of damage when the protective netting 5 is disassembled and transported separately. Compared with the traditional welding method of fixing the protective netting 5 to the frame, this rivet fixing method allows for direct replacement of the damaged part of the protective netting 5 when it is damaged, avoiding the need for re-welding the damaged protective netting 5, thus improving its protective effect. At the same time, the rivet fixing method also facilitates subsequent disassembly and replacement.

[0029] The working process of the pin-type quick-installation and quick-disassembly integrated fixed protective railing provided by this utility model is as follows: Based on the length and shape of the protected area at the construction site, determine the required quantities of end components 1, standard components 2, uprights 3, and connecting columns 4. Align the uprights 3 with the protrusions 11 on the outer side of the end components 1, and use bolts 31 to pass through the threaded holes of the protrusions 11 and tighten them to the corresponding positions on the uprights 3. At the same time, use expansion bolts to fix the steel plates at the bottom of the uprights 3 and connecting columns 4 to the ground, ensuring that the uprights stand firmly at the boundary of the protected area.

[0030] Align the first plug group 6 on the inside of the front end component 1 with the second plug group 7 on one side of the first standard component 2, so that the plugs are stacked vertically and inserted into the transverse interface 42 of the connecting post 4. Sequentially stack and splice the remaining standard components 2 using the plugs from the first and second plug groups, supporting each standard component with the connecting post 4 underneath. Finally, assemble the second plug group 7 on the inside of the rear end component 1 with the first plug group 6 of the last standard component 2 to complete the main assembly of the guardrail. Finally, the connecting rod 9 is vertically inserted into the slot 41 at the top of the connecting column 4, so that its upper and lower ends pass through the through holes 8 on the first plug group 6 and the second plug group 7 respectively. Although the locking ring 91 is movably connected to the top of the connecting rod 9, the locking ring 91 and the top of the connecting rod 9 are integrated. Then, the locking ring 91 is fastened to the limit hook 43, and the limit hook 43 is rotated so that the notch end of the limit hook 43 faces downward, thereby completing the vertical fixation, so as to prevent personnel from arbitrarily disassembling the connecting rod 9 from outside the guardrail.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
