AI Technical Summary
Construction of existing walkways on mountainsides is inconvenient, especially for cantilever walkways which require large foundations and have difficult welding of connecting joints, affecting construction efficiency and stability.
The system uses independent foundations to install Y-shaped steel columns to form a support system. Different types of connection nodes are connected by welds, and closed steel plates are installed at the railings to enhance stability and decorative effect.
It reduces the area occupied by the foundation, improves the convenience of construction, enhances the strength of the connection nodes and the stability of the railings, and ensures the structural stability and aesthetics of the walkway.

Abstract
Claims
1. A spatial curved steel structure aerial walkway, characterized in that, It includes a foundation (1), a support structure (2) installed on the foundation (1), a longitudinal beam (3) connecting adjacent support structures (2), and a bridge deck pavement (4) on the top surface of the support structure (2) and the longitudinal beam (3). The support structure (2) includes a Y-shaped steel column (2.1) and a crossbeam (2.2) connected to the bifurcation end of the Y-shaped steel column (2.1). The longitudinal beam (3) is connected between the crossbeams (2.2).
2. A spatial curved steel structure aerial walkway according to claim 1, characterized in that, The Y-shaped steel column (2.1) includes a main support column and a branch column connected to the upper end of the main support column. The crossbeam (2.2) is connected between the branch columns. A Y-shaped steel plate is provided at the connection between the main support column and the branch column. The lower end of the Y-shaped steel plate (2.3) is inserted into the main support column for fixation, and the upper end is inserted into the branch columns for fixation.
3. A spatial curved steel structure aerial walkway according to claim 2, characterized in that, The main support column is provided with a base plate (2.4) at its lower end. The base plate (2.4) is bolted to the foundation (1). A rib plate (2.5) is connected between the main support column and the base plate (2.4).
4. A spatial curved steel structure aerial walkway according to claim 1, characterized in that, The Y-shaped steel column (2.1), the crossbeam (2.2) and the longitudinal beam (3) are connected by welds. When the connection is greater than or equal to 90°, a butt weld is used. When the connection is less than 90°, a base plate (5) is set at the connection, and the connection is connected by welds outside the base plate (5).
5. A spatial curved steel structure aerial walkway according to claim 1, characterized in that, Secondary beams (4 and 4) are spaced apart between the longitudinal beams (3).
6. A spatial curved steel structure aerial walkway according to claim 1, characterized in that, The bridge deck paving (4) includes horizontal joists (4.1) spaced apart along the outline of the boardwalk, longitudinal joists (4.2) connected between the horizontal joists (4.1), and wooden flooring (4.3) laid on the framework formed by the horizontal joists (4.1) and longitudinal joists (4.2).
7. A spatial curved steel structure aerial walkway according to claim 6, characterized in that, The bridge deck pavement (4) is also equipped with railings (4.5) on both sides, and the posts of the railings (4.5) are fixedly connected to the longitudinal keel (4.2).
8. A spatial curved steel structure aerial walkway according to claim 7, characterized in that, The lower end of the railing (4.5) is provided with closed steel plates (4.6) on its inner and outer sides respectively. The closed steel plates (4.6) are L-shaped, with one end fixedly connected to the upright of the railing (4.5) and the other end supported on the horizontal keel (4.1).
