A construction method for a protective hyperbolic rotating teardrop-shaped staircase structure according to any one of claims 1 to 9, characterized in that: The specific steps are as follows: Step 1: Conduct three-dimensional modeling of the staircase unit (2), staircase guardrail (3), corner platform (4), platform guardrail (5), bottom floor (1), top floor (10) and top floor guardrail (11); focus on deepening the staircase guardrail (3), platform guardrail (5) and top floor guardrail (11) to ensure that their linear shapes are smooth; Step 2: When constructing the bottom floor (1), the top floor (10) and the corner platform (4), pre-install the embedded connecting parts (17) and the embedded base (18); thereby ensuring the subsequent installation of the guardrail; after the construction of the bottom floor (1) and the top floor (10) is completed, the staircase unit (2) and the corner platform (4) are constructed, wherein the staircase unit (2) and the corner platform (4) are both steel components; Step 3: When constructing the corner platform (4), the main vertical columns (42) and the diagonal bracing columns (43) are first constructed, and a stiffening rib is provided along the circumferential direction on the bottom surface of the main platform (41); then, the stair guardrail (3), the platform guardrail (5) and the top floor guardrail (11) are constructed, and their linear shapes are checked to see if they meet the design requirements; After the staircase unit (2) is constructed, a water drop decorative panel (14) is installed on the side of the staircase; Step 4: According to the design of the teardrop-shaped staircase structure, the keel assembly (13) and the reinforced support assembly (15) are installed; and the ceiling frame unit (9) and the suspension rod (8) are installed. The ceiling frame unit (9) is a frame-like structure formed by the ceiling vertical keel (1311) and the ceiling horizontal keel (1312), and the vertical suspension rod (8) is installed; The overlapping parts of the keel assembly (13) and the reinforcing support assembly (15) are fixedly connected and a deformation sensor and a force sensor are arranged at the fixed connection, and deformation sensors and force sensors are also arranged at each connection node of the reinforcing support assembly (15); after the force and deformation meet the design requirements, the next step of construction is carried out; Step 5: Based on the height difference changes on site and the structural differences in the horizontal direction, use high-precision measurement equipment such as total stations and laser rangefinders to perform horizontal projection layout on the floor, measure and mark the points using a plane rectangular coordinate system, and then organize the data on the CAD drawing; Step 6: Layout is performed in combination with the staircase structure that has been constructed, and then a relevant three-dimensional model is established, and then stability and feasibility are verified through on-site local sample construction; the three-dimensional point cloud data obtained by scanning the site is compared with the three-dimensional model to verify the accuracy of the three-dimensional model, and the three-dimensional model is updated according to actual conditions to further deepen and confirm the shape of the water drop decorative panel (14) in the water drop unit (6); Step 7: Based on the confirmed completed three-dimensional model, a detailed drawing is made, and the water drop decorative panel (14) is divided into blocks according to the installation requirements, and a processing drawing is generated, and then the processing is optimized and produced according to the processing drawing; the produced divided water drop decorative panels (14) are numbered in parallel, and then assembled on site. After the installation accuracy meets the requirements, the finishing coating is uniformly applied, thereby completing the installation of the water drop type staircase structure.
