Technical Field

[0001] This utility model relates to the field of metal railing technology, and in particular to a metal railing that can be flexibly disassembled and assembled. Background Technology

[0002] Metal railings, as an important safety protection facility, are widely used in construction, transportation, and other fields, playing an irreplaceable role in ensuring personnel safety and maintaining environmental aesthetics. With the acceleration of urbanization and continuous socio-economic development, people have increasingly higher demands for public facilities, especially in terms of safety, durability, and ease of installation. Against this backdrop, traditional fixed metal railings have gradually shown certain limitations, failing to meet the diverse needs of modern engineering projects, thus driving the research and application of flexibly detachable metal railings.

[0003] In practical engineering, various methods are typically employed to ensure the safe and stable installation of metal railings. One common method is to fix the railing posts to the ground using cast-in-place concrete. However, these metal railing installation methods generally suffer from insufficient flexibility, inconvenient maintenance, and high costs. Especially when facing frequent layout changes or temporary application scenarios, traditional fixing methods often fall short of expectations. Therefore, developing a new type of metal railing system that ensures structural stability, ease of installation and disassembly, and reasonable cost has become an urgent technical challenge. Utility Model Content

[0004] This application provides a metal railing that can be flexibly disassembled and assembled, facilitating quick and stable installation of the metal railing.

[0014] Preferably, the bottom of the bolt mounting box is provided with a connecting post, and the connecting post is fixed to the embedded part by welding.

[0015] By adopting the above technical solution, the connecting post enhances the mechanical strength between the bolt mounting box and the embedded part during use, ensuring a stable connection and effectively preventing loosening or detachment caused by external forces. The application of welding further improves the reliability and durability of the connection.

[0016] Preferably, a connecting rod is provided between the connecting columns, and the connecting rod is used to connect the connecting rods on both sides to each other, thereby improving the stability of the bolt mounting box.

[0017] By adopting the above technical solution, connecting rods are installed between the connecting columns during use, which effectively enhances the overall structural strength of the bolt mounting box, preventing deformation caused by external impacts or prolonged use, thereby improving the stability and service life of the metal railing. The design of the connecting rods also ensures a tight fit between the components, further enhancing the safety and reliability of the system.

[0018] Preferably, the surface of the bolt mounting box is coated with an anti-corrosion coating, which is used to improve the corrosion resistance of the bolt mounting box.

[0019] By adopting the above technical solution, the anti-corrosion coating on the surface of the bolt mounting box can effectively improve its corrosion resistance in outdoor environments, extend its service life, and reduce maintenance costs.

[0020] Preferably, the embedded part includes a welded plate and anchor bars, the anchor bars being used to enhance the bond between the embedded part and the concrete.

[0021] By adopting the above technical solution, the embedded parts include welded plates and anchor bars. This design enhances the bonding force between the embedded parts and the concrete, improving the stability and safety of the entire metal railing. The use of anchor bars allows the embedded parts to be embedded more deeply into the concrete, effectively preventing displacement or detachment caused by external forces.

[0022] In summary, this application has the following beneficial effects:

[0023] 1. The present invention provides a flexible detachable metal railing. The connection method of fixing the railing post and the embedded part by tightening the hexagonal screw and bolt mounting box not only ensures the stable connection between the railing post and the embedded part, but also realizes flexible installation and disassembly, which is convenient for maintenance and replacement.

[0024] 2. The present invention provides a flexible detachable metal railing with a bolt mounting box having a pre-embedded part at the bottom and fixed to the concrete by welding, which enhances the wind pressure resistance and seismic performance of the entire system and improves the overall safety of the metal railing.

[0025] 3. The present invention provides a flexibly detachable metal railing. The fixing structure inside the bolt mounting box can effectively further fix the railing posts, ensuring the stability of the railing posts and extending the service life of the metal railing.
