[0031] Edge protection railings are safety devices installed in dangerous areas such as construction sites and foundation pit edges to ensure personnel safety. Traditional railings often use a simple combination of single-tube posts and crossbars. This type of railing with single-tube posts has poor support performance and struggles to provide effective overturning resistance when subjected to strong wind loads, accidental collisions, or vehicle impacts, leading to tilting or even collapse due to lateral forces.

[0032] Therefore, such as Figures 1 to 4 As shown, the tripod column assembly proposed in this utility model includes a column 100. The column 100 is provided with a support frame 110 and a plug-in fixing structure. The support frame 110 is provided on one side of the column 100, and the support frame 110 and the column 100 form a triangular structure. The outer wall of the column 100 is provided with an installation part 120. The installation part 120 cooperates with the first fastener to fix the guardrail. The plug-in fixing structure is used to plug into the ground to fix the column 100.

[0033] The utility model's triangular post assembly has at least the following beneficial effects: The post 100 is provided with a support frame 110, and the support frame 110 and the post 100 together form a triangular structure. This triangular structure provides more stable support and better resists external forces, such as wind and collisions with people, reducing the possibility of the guardrail tilting or collapsing, thus providing more reliable safety. Simultaneously, the bottom of the post 100 is provided with a plug-in fixing structure, which firmly fixes the post 100 to the ground, providing stable support and improving the overall stability of the guardrail structure.

[0034] In some embodiments of this utility model, such as Figures 1 to 4 As shown, the plug-in fixing structure includes a fixing member 130 and a clamping plate 140. The fixing member 130 and the clamping plate 140 are the same in shape and size. The fixing member 130 is located on the side of the column 100 facing the support frame 110, which helps to enhance the supporting force of the support frame 110 on the column 100. A plug rod 150 is provided between the clamping plate 140 and the fixing member 130. The plug rod 150 has a cylindrical cross-section and is used to plug into the ground. The clamping plate 140 and the fixing member 130 are detachably connected by a second fastener. The second fastener can push the clamping plate 140 to press against and fix the plug rod 150. It can be understood that the second fastener is a bolt with nuts connected to both ends. After the plug rod 150 is plugged into the ground, the clamping plate 140 is aligned with the fixing member 130, and the bolt passes through the clamping plate 140 and the fixing member 130. By tightening the nuts at both ends of the bolt, the distance between the fixing piece 130 and the clamping piece 140 is adjusted, thereby pressing against the fixing rod 150. The whole process is simple to operate and the fixing effect is firm and reliable, ensuring that the guardrail can withstand a certain degree of external forces such as personnel collisions and wind in daily use.

[0035] Furthermore, in some embodiments of this utility model, such as Figure 4 As shown, there are two insertion rods 150, which are respectively set on both sides of the support frame 110. The symmetrically distributed insertion rods 150 on both sides can evenly distribute the external force borne by the column 100, effectively avoiding the risk of the column 100 tilting or overturning due to excessive force on one side.

[0036] In other embodiments of this utility model (not shown in the figures), the insertion and fixing structure includes a first limiting ring, a second limiting ring, and a plug rod 150. The first limiting ring and the second limiting ring are longitudinally spaced apart on the column 100, and the first limiting ring has an opening. The top of the plug rod 150 is provided with a limiting part, and the plug rod 150 has a first position and a second position. The plug rod 150 slides through the first limiting ring and the second limiting ring. When in the first position, the plug rod 150 passes through the first limiting ring and the second limiting ring, and the limiting part abuts against the first limiting ring, thereby restricting the movement of the plug rod 150 towards the ground. When in the second position, the plug rod 150 passes through the second limiting ring, and the limiting part abuts against the second limiting ring, thereby restricting the movement of the plug rod 150 towards the ground. The limiting part can pass through the opening of the first limiting ring, so that the insertion rod 150 can move to the second position and complete the insertion and fixing with the ground. The process is simple to operate and the fixing effect is firm and reliable, which provides stable support for the post 100 and thus improves the overall stability of the guardrail structure.

[0037] In some embodiments of this utility model, such as Figures 1 to 3 As shown, the fixing member 130 extends along the length direction perpendicular to the column 100, and the fixing member 130 is provided with a first connecting groove 131, which extends along the length direction of the fixing member 130. The clamping piece 140 is provided with a second connecting groove 141. The length and width of the first connecting groove 131 and the second connecting groove 141 are equal. There are two of each of the first connecting groove 131 and the second connecting groove 141. The two first connecting grooves 131 are symmetrically arranged along the center line of the column 100, and the two first connecting grooves 131 correspond one-to-one with the two second connecting grooves 141. The second fastener connects the first connecting groove 131 and the second connecting groove 141. The second fastener can move along the extension direction of the first connecting groove 131 to adjust the connection position, thereby allowing the insertion rod 150 to be inserted into a suitable position, improving the flexibility of installation.

[0038] In some embodiments of this utility model, such as Figures 1 to 4 As shown, there are multiple mounting components 120, which are arranged at intervals along the longitudinal direction of the post 100. Each mounting component 120 extends perpendicular to the length of the post 100, and its length is equal to that of the fixing component 130. Both the mounting components 120 and the fixing components 130 are fixed to the post 100 by welding. The mounting components 120 are located on the side of the post 100 facing away from the support frame 110. The multiple mounting components 120 provide multiple connection points for fixing the guardrail and the post 100, enhancing the connection stability between the guardrail and the post 100, thereby comprehensively improving the safety performance of the guardrail.

[0039] In some embodiments of this utility model, such as Figures 1 to 4As shown, the mounting component 120 has two connecting holes 121 spaced apart. The two connecting holes 121 are symmetrically arranged on both sides of the column 100. Guardrails can be connected to both sides of the column 100. With the first fastener, the installation of the column 100 and the guardrail can be completed quickly, improving construction efficiency.

[0040] In some embodiments of this utility model, such as Figures 1 to 4 As shown, a base plate 160 is connected to the bottom of the column 100. The base plate 160 is a regular rectangle, and the column 100 is perpendicular to the base plate 160. The column 100 and the base plate 160 are fixed together by welding. The base plate 160 has multiple mounting holes 161 spaced apart. The mounting holes 161 cooperate with a third fastener to fix the column 100. The base plate 160 provides a stable base, evenly distributing the load borne by the column 100 to the ground, effectively preventing the column 100 from tilting due to concentrated force, and providing stable support for the column 100. It should be noted that the third fastener can be an expansion bolt or anchor bolt, etc., and can be flexibly selected according to different ground materials, such as concrete, steel plate, wooden platform, etc., to firmly fix the column 100 to the ground.

[0041] In some embodiments of this utility model, such as Figures 1 to 4 As shown, the cross-sections of the post 100 and the support frame 110 are rectangular. Both the post 100 and the support frame 110 are made of hollow aluminum alloy tubing. Aluminum alloy tubing possesses certain strength and corrosion resistance, ensuring the guardrail maintains good service condition for a long period. The wall thickness of both the post 100 and the support frame 110 is A, where 2mm ≤ A ≤ 3.5mm. This wall thickness of 2mm to 3.5mm ensures structural strength while avoiding excessive thickness that would increase cost and weight, ensuring stability even in complex construction environments.

[0042] In some embodiments of this invention, the surfaces of the column 100 and the support frame 110 are coated with a composite anti-rust coating, which includes an epoxy primer layer and a polyurethane topcoat layer. The epoxy primer layer can adhere tightly to the surfaces of the column 100 and the support frame 110, blocking the penetration of corrosive media such as moisture, oxygen, and salt spray. The polyurethane topcoat film is smooth, which can further block the penetration of corrosive media and enhance the anti-rust effect of the epoxy primer layer.

[0043] The edge protection railing according to an embodiment of the present utility model includes a tripod post assembly according to an embodiment of the present utility model.

[0044] According to the embodiments of the present invention, the edge protection railing, by employing the triangular frame post assembly of the present invention, forms a triangular structure with the post 100 and the support frame 110, which has stability and can effectively resist external impacts such as wind and personnel collisions, greatly reducing the risk of the railing tilting or collapsing. The plug-in fixing structure, through the cooperation of the fixing member 130, the clamping piece 140, and the plug rod 150, can firmly anchor the post 100 to the ground, enhancing the adaptability of the railing in complex terrain and harsh environments, and ensuring that it is not easily displaced.

[0045] Reference Figure 5 In this embodiment of the invention, the post 100 can be positioned between two guardrails, connecting and transitioning between them, or it can be connected to both sides of the guardrails, providing stable support. Multiple guardrails and multiple posts 100 can be spliced ​​together according to actual needs, thereby extending the length of the guardrails. Assembly is flexible and convenient, and multiple posts 100 can provide support for the guardrails from different positions, thus improving the overall stability of the guardrail structure.

[0046] Other components and operations of the edge protection railing according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
