[0025] Please refer to Figures 1-3 One embodiment of this utility model provides a guardrail post and guardrail to solve the problems of complex installation process of guardrail posts and handrails, large material consumption and high cost of solid guardrail posts, and heavy load on building structures in the prior art.

[0026] Specifically, please refer to Figure 1 A perspective view of a guardrail provided for an embodiment of this utility model. Figure 2 This is an exploded view of a guardrail according to an embodiment of the present invention. The guardrail post 10 includes a rod portion 11 and a support portion 12 connected to each other. The rod portion 11 is a vertically extending columnar structure. The support portion 12 has a support opening 121 at one end away from the rod portion 11. The shape of the support opening 121 is adapted to the outer contour of the handrail 20. The end of the support portion 12 away from the rod portion 11 branches out to form two arms, and the support opening 121 is formed between the two arms. A connector 122 is provided inside the support opening 121. In this embodiment, the curvature of the connector 122 is adapted to the contact surface of the handrail 20, and the connector 122 is fixed inside the support opening 121 by welding. The rod portion 11 includes a housing 131 and a support member 13 disposed inside the housing 131. The rod portion 11 adopts a hollow housing 131 and a support member 13 disposed inside the housing 131, forming a cavity inside the housing 131. The support member 13 ensures the overall support strength, which can significantly reduce weight and installation load while ensuring structural strength. Preferably, the two support arms forming the support opening 121 are symmetrically arranged.

[0027] In the above technical solution, on the one hand, the connector 122 inside the support opening 121 enhances the tightness of the connection between the handrail 20 and the support part 12, avoids the loosening problem that may occur if it is simply placed inside the support opening 121, and reduces the rigid friction between the handrail 20 and the support part 12; on the other hand, the hollow structure of the pole part 11 can significantly reduce the weight while ensuring the structural strength, reduce the installation load, reduce the load-bearing burden of the building structure, and effectively reduce the cost while meeting the overall stress requirements.

[0028] As a further improvement of this utility model, a first fastener 111 is provided on the outside of the housing 131. In this embodiment, the first fastener 111 is a stainless steel bolt. The first fastener 111 is arranged in a direction perpendicular to the axis of the rod 11, passes through the housing 131 and is threadedly connected to the internal support member 13 to form a mechanical fixed fit. To ensure the connection strength, two first fasteners 111 are provided for each rod 11, and are arranged at intervals along the height direction of the rod 11.

[0029] During assembly, one end of the support member 13 is first welded to the support part 12, and the other end is inserted into the housing 131 for initial fixation through welding. Then, holes are drilled and tapped at predetermined positions in the housing 131, and the first fastener 111 is passed through the housing 131 and screwed into the support member 13 until the head of the first fastener 111 is tightly fitted to the outer surface of the housing 131. This dual connection method of welding and mechanical fastening effectively compensates for the potential for incomplete welding in single welding, ensuring more reliable force transmission between the support member 13 and the support part 12.

[0030] In the above technical solution, on the one hand, the first fastener 111 strengthens the fixing effect between the support member 13 and the support part 12 through mechanical connection, and forms a synergistic effect with welding, which greatly improves the structural stability of the guardrail post 10; on the other hand, the externally operable fastener design provides convenience for later maintenance and extends the overall service life of the guardrail post 10, which is especially suitable for outdoor railing systems of large public buildings.

[0031] As a further improvement of this utility model, the outer surface of the housing 131 is provided with at least one slot 112. In this embodiment, two slots 112 are preferably provided, symmetrically distributed on both sides of the housing 131. The slot 112 is generally elongated and has a U-shaped cross-section. The U-shaped slot 112 provides an open snap-fit ​​interface for external components, which can be adapted to various functional components: for example, it can snap on rubber protective strips to reduce the impact force during personnel collisions, snap on PVC decorative strips to enrich the appearance, or snap on metal signs to mark safety information. During assembly, simply align the insertion end of the component with the U-shaped slot 112. No additional fasteners are required, and installation can be completed by a single person, saving assembly time compared to traditional bolt connections.

[0032] From a stress perspective, the two side walls of the U-shaped slot 112 can evenly distribute the radial external force. When the locking component is impacted, the slot wall of the slot 112 absorbs energy through slight deformation, which protects the component itself and prevents the housing from being damaged due to excessive local stress.

[0033] Furthermore, the open structure of the U-shaped slot 112 facilitates the disassembly and replacement of components later. During maintenance, it can be removed simply by gently pushing along the opening of the slot 112, without the need for special tools. This simplifies the assembly process of external components, enhances the functional expandability of the guardrail post, and its diverse adaptability allows the guardrail post to meet the functional and decorative needs of different scenarios.

[0034] As a further improvement to this utility model, please refer to Figure 3 The support member 13 has an H-shaped cross-section and is integrally formed from two parallel horizontal plates 132 and a central vertical plate 133. The dimensions of the horizontal plates 132 or vertical plates 133 of the H-shaped support member 13 are approximately the same as the dimensions of the internal cavity of the housing 131, and the shape / outline of the horizontal plates 132 or vertical plates 133 of the H-shaped support member 13 are also approximately the same as the shape / outline of the internal cavity of the housing 131. Preferably, the two openings 134 of the H-shaped support member 13 are respectively oriented in the same direction as the two slots 112, and their opening widths are adapted to the widths of the slots 112. At least one side wing 135 of the support member 13 extends to the inner wall of the slot 112 and abuts against it. In this embodiment, the thickness of the H-shaped support member 13 is consistent with the width of the inner wall of the rod 11, ensuring that the support member 13 can fill the internal space of the rod 11.

[0035] This structural design enables the H-shaped support 13 and the slot 112 to work synergistically: when the guardrail 40 is embedded in the slot 112 and subjected to lateral force, the inner wall of the slot 112 transfers the force to the side wings of the H-shaped support 13. The shear resistance of the H-shaped section disperses the stress, preventing the slot 112 from deforming due to excessive local stress. At the same time, the vertical plate of the H-shaped support 13 is located at the central axis of the pole 11, which can enhance the overall bending resistance of the pole 11. Especially when the guardrail post 10 is subjected to lateral torque, it can limit the torsional deformation of the pole 11 through its own rigidity.

[0036] During assembly, the H-shaped support 13 fits snugly against the inner wall of the pole 11, and the support 13 abuts against the inner wall of the slot 112, ensuring that the two form a unified structure that is synchronously stressed. When the guardrail post is impacted by an external force, the force is transmitted sequentially along the guardrail panel 40, the slot 112, and the H-shaped support 13, and the force is efficiently dispersed through the cross-sectional characteristics of the H-shaped support 13.

[0037] In the above technical solution, the opening of the H-shaped support member 13 is set to correspond with the slot 112 to form a targeted reinforced support, which effectively improves the structural strength of the slot 112 area and avoids the deformation of the pole 11 due to stress after the installation of the guardrail 40. The H-shaped cross section makes the support member 13 have higher rigidity with the same amount of material, which not only reduces the overall weight, but also optimizes the force transmission path and significantly improves the overall stability of the guardrail post.

[0038] As a further improvement of this utility model, the connector 122 consists of a connecting piece 1221 and a second fastener 1222. The connecting piece 1221 is generally a rectangular metal sheet, which is disposed inside the support opening 121. The length of the connecting piece 1221 is greater than the width of the support opening 121, and both ends of the connecting piece 1221 extend outward from the support opening 121 to form outwardly extending fixed wings 12211. The lower surface of the connecting piece 1221 fits against the inner wall of the support opening 121 to ensure a tight fit with the handrail 20.

[0039] The second fastener 1222 is disposed on the side of the connecting piece 1221 away from the handrail 20, i.e., on the lower surface of the connecting piece 1221. The number of the second fasteners 1222 is adapted to the length of the fixed wing 12211. In this embodiment, two second fasteners 1222 are spaced apart along the length direction on each fixed wing 12211. After passing through the connecting piece 1221, the second fasteners 1222 are connected to the handrail 20, so that the handrail 20 is tightly fixed inside the support opening 121, realizing a rigid fixing structure for the handrail 20.

[0040] During assembly, the handrail 20 is first placed inside the support opening 121, so that the outer surface of the handrail 20 is in contact with the upper surface of the connecting piece 1221. Then, the second fastener 1222 is screwed in from below the fixing wing 12211 until the head of the second fastener 1222 is flush with the surface of the fixing wing 12211. At this point, the handrail 20 is tightly fitted to the inner wall of the support opening 121 due to the pressure of the connecting piece 1221, preventing any loosening or gaps. The design of the fixing wing 12211 extending out of the support opening 121 provides sufficient operating space for the second fastener 1222 and also allows it to connect to the handrail, strengthening the fixation of the handrail 20.

[0041] In the above technical solution, the connecting piece 1221 cooperates with the second fastener 1222 to effectively prevent the handrail 20 from falling off due to vibration and collision during long-term use.

[0042] As a further improvement of this utility model, a wooden pad 1223 is provided between the handrail 20 and the connecting piece 1221. The wooden pad 1223 is roughly strip-shaped and its length is roughly the same as that of the connecting piece 1221. During assembly, the wooden pad 1223 is tightly clamped between the handrail 20 and the connecting piece 1221, forming surface contact with both. The second fastener 1222 is a stainless steel self-tapping screw. During installation, the stainless steel self-tapping screw passes through the connecting piece 1221 and the wooden washer 1223 in sequence before being screwed into the handrail 20 until the screw head is completely recessed into the connecting piece 1221. At this point, the wooden washer 1223 undergoes slight deformation due to compression, tightly filling the gap between the handrail 20 and the connecting piece 1221. The wooden washer 1223 buffers the rigid collision between the handrail 20 and the metal connecting piece 1221, avoiding wear and noise caused by direct contact between the two. The stainless steel self-tapping screw, with its excellent corrosion resistance, can adapt to outdoor humid environments, avoiding the problem of rust failure after long-term use; the countersunk head design ensures the flatness of the surface of the connecting piece 1221, preventing the screw head from being exposed and causing safety hazards; and the self-tapping thread structure eliminates the need for pre-drilling and tapping in the handrail 20, simplifying the installation process and improving construction efficiency. In the above technical solution, the combination of wooden washer 1223 and stainless steel self-tapping screw not only optimizes the tightness of the connection between handrail 20 and connecting piece 1221, but also protects the material of handrail 20 from damage, taking into account both functionality and durability, so that the service life of connector 122 matches the overall service life of guardrail post, which is especially suitable for the combination scenario of wooden handrail 20 and metal guardrail post 10.

[0043] As a further improvement of this utility model, the support member 13 is welded to the support portion 12 at one end near the support portion 12, and the support member 13 is disposed through the central axis of the rod portion 11. One end of the support member 13 extends to the forked root position of the support portion 12 and is fixedly connected to the support portion 12 by welding, ensuring that the external force borne by the support portion 12 is transmitted to the rod portion 11.

[0044] During assembly, the support member 13 is welded to the support part 12 to ensure the connection strength. When the handrail 20 is subjected to lateral thrust, the external force is transmitted to the support member 13 through the support part 12, avoiding the deformation problem that may occur if the shell 131 is supported by its own strength alone.

[0045] In the above technical solution, on the one hand, the support member 13 inside the shell 131 forms a rigid connection through the welded support part 12, which significantly improves the overall bending resistance of the guardrail post 10; on the other hand, the support member 13 is hidden inside the shell 131, which does not affect the appearance and can provide long-term stable mechanical support for the guardrail post through the high strength characteristics of the metal material, which is especially suitable for high-safety scenarios such as balconies and corridors of high-rise buildings. This utility model also provides a guardrail, including a handrail 20, a mounting groove 30, a railing panel 40, and the aforementioned guardrail posts 10; multiple guardrail posts 10 are arranged at intervals, the handrail 20 is placed inside the support opening 121, the handrail 20 is connected to the support part 12 through the connector 122, and the shape of the support opening 121 is adapted to the outer contour of the handrail 20; multiple guardrail posts 10 are arranged at intervals along the horizontal direction of the building structure, and the handrail 20 is arranged horizontally and placed inside the corresponding support opening 121 of each guardrail post 10. The outer surface of the handrail 20 is tightly fitted with the connector 122 inside the support opening 121, and the handrail 20 is fixedly connected to the support part 12 through the connector 122. In some embodiments, the connector 122 has a pre-set threaded hole, and after the handrail 20 is inserted, it is fastened to the handrail 20 by screws passing through the threaded hole, so that the connector 122 becomes the force transmission medium between the handrail 20 and the support part 12.

[0046] The mounting groove 30 is fixed to the surface of the building structure, including but not limited to the edge of a balcony and the base of a stair handrail. The length direction of the mounting groove 30 is consistent with the arrangement direction of the guardrail posts 10. The bottom end of the rod 11 is inserted into the mounting groove 30 and fixed thereto, so that the guardrail post 10 is firmly connected to the building structure.

[0047] A guardrail 40 is disposed between two adjacent poles 11. In some embodiments, the guardrail 40 is made of tempered glass, and its length is adapted to the spacing between adjacent poles 11, and its height is adapted to the height of the poles 11. The two side edges of the guardrail 40 are embedded in the slots 112 of the corresponding side poles 11, so that the guardrail 40 and the two side poles 11 form a snap-fit ​​engagement.

[0048] The balustrade 40 creates a continuous barrier surface on the guardrail posts, effectively preventing people or objects from passing under the handrail 20 and enhancing safety. Simultaneously, the tempered glass balustrade 40 offers excellent light transmission without obstructing the view, making it particularly suitable for viewing platforms, balconies, and other locations requiring an unobstructed view. The interlocking mechanism between the slot 112 and the balustrade 40 achieves lateral closure of the guardrail posts, significantly improving safety performance.

[0049] As a further improvement of this utility model, the bottom of the mounting groove 30 is provided with bases 31 at intervals, and one end of the support member 13 extends out of the bottom end of the rod 11 and is welded to the bases 31 at the bottom of the mounting groove 30. The bottom of the mounting groove 30 is provided with bases 31 at intervals along its length. The bottom of the bases 31 is fixed to the building structure, and the top of the bases 31 is welded to the bottom of the mounting groove 30. At the same time, the top of the bases 31 is reserved with welding positions adapted to the support members 13. The spacing of the bases 31 is consistent with the arrangement spacing of the guardrail posts 10, ensuring that each guardrail post 10 can correspond to a base 31 to form an independent force support point.

[0050] During assembly, the support 13 is welded to the base 31 to ensure connection strength. When the handrail 20 is subjected to lateral thrust, the external force is transmitted sequentially through the support 12 to the support 13, and then directly to the building structure through the base 31, forming a complete force flow path and avoiding deformation problems that may occur if the support 11 is supported by its own strength alone.

[0051] As a further improvement of this utility model, the bottom of the handrail 20 is provided with a fixing groove 21, the upper edge of the railing 40 is embedded in the fixing groove 21, and the lower edge of the railing 40 is embedded in the mounting groove 30. To enhance stability, elastic seals are filled in the gaps between the railing 40 and the fixing groove 21, and between the railing 40 and the mounting groove 30. These seals can buffer the vibration of the railing 40 under external force and prevent rainwater, dust, etc. from entering the slot 112.

[0052] As a further improvement of this utility model, the support member 13 is made of steel. Steel has high strength and good plasticity and toughness, which can meet the structural strength requirements of the support member 13 and provide stable mechanical support for the guardrail post. The steel support member 13 can be easily processed into the required H-shaped cross-section through processes such as cutting, welding, and rolling, and the processing accuracy is high, which can ensure the compatibility of the support member 13 with components such as the rod 11 and the slot 112. By selecting steel as the material of the support member 13, its high strength and easy processing characteristics are utilized to ensure the structural strength and processing compatibility of the support member 13, thereby ensuring the overall safety performance of the guardrail post.

[0053] As a further improvement of this utility model, the guardrail post 10 is made of stainless steel. Stainless steel has excellent corrosion resistance, heat resistance, and mechanical properties. The passivation film formed by its chromium-nickel alloy composition can effectively resist the erosion of air, moisture, and general corrosive media. Even in humid outdoor environments, it is not easy to rust and can maintain the stability and integrity of the structure for a long time. At the same time, stainless steel has good processing performance and can be precisely formed into the pole part 11 and the support part 12 through bending, welding, and other processes to meet the complex structural design requirements of the guardrail post 10.

[0054] The exterior of the guardrail post 10 is coated with a copper-like finish. This finish not only gives the guardrail post 10 a retro and elegant appearance, allowing it to coordinate with Chinese, neoclassical, and other architectural styles and enhance its decorative appeal, but also further strengthens the surface protection performance on top of the stainless steel base material. This prevents stains from adhering or the stainless steel surface from deteriorating due to long-term outdoor exposure, thus meeting functional requirements and adapting to diverse decorative styles, expanding the application scenarios of the guardrail post.

[0055] As a further improvement of this utility model, the handrail 20 is made of North American oak, and its surface is coated with a polyurethane coating. The handrail 20 is made of North American oak, which has a dense grain and hard texture. After being cut and polished, its surface is coated with a polyurethane coating. The natural wood structure of North American oak provides basic mechanical support for the handrail 20, and its compressive strength and bending strength along the grain can meet the force requirements of daily gripping and lateral leaning. The polyurethane coating forms a continuous film through intermolecular cross-linking reactions, tightly adhering to the wood surface, isolating the wood from external factors such as moisture and ultraviolet rays, while also complementing the oak grain to enhance visual texture. The warm texture of North American oak contrasts with the copper-like stainless steel of the guardrail post 10, enhancing the overall visual level. The high elasticity of the polyurethane coating can adapt to the slight deformation of the wood, preventing coating cracking and ensuring long-term stable protective performance.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
