[0015] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0016] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0017] Example 1 Example 1 of this specification provides a method for constructing an arc fence on the edge of a water system cloud bridge concrete structure. Figure 1 Shown, including: S1. Camber the steel plate according to the construction curvature requirements of the water system cloud bridge; S2. Set the legs on the steel plate at equal intervals; S3. Weld the steel plate to the side of the structural steel bar and use it as a side sealing template during the construction of the concrete structure platform; S4. Carry out concrete construction. After the concrete construction is completed, install U-shaped corner brackets on the steel plate at intervals; S5. Install the grating railing on the U-shaped corner bracket.

[0018] In one possible implementation, the factory processes curved steel plates according to the arc width of the curved cloud bridge and the requirements of the drawings. Steel legs are then welded to the plates at even intervals. During the construction of the cloud bridge structure, the concrete base formwork is first laid, the structural platform reinforcement is tied, and then the curved steel plates are installed. The steel legs are welded to the structure to seal the side formwork. After the structural construction is completed, the steel plates can be used as temporary protective anchors. During the installation of the formal guardrails, the steel plates are first derusted and polished, then U-shaped brackets are welded to the plates and a white protective coating is applied. The grating railings are installed according to the drawings and secured with screws. For example, 5mm thick steel plates are installed on the sides of the concrete platform of the cloud bridge, with a width that meets the structural thickness of 150mm and the decorative surface thickness of 30mm (total thickness 180mm). The steel plates are pre-curved to match the arc of the cloud bridge and laid along the length of the bridge. A 100mm long φ6 threaded steel leg is set on the steel plate and overlap-welded with the structural steel bars. The steel plate serves as the side sealing template during the construction of the concrete structure platform.

[0019] This embodiment can utilize the body coefficients of the two materials, steel plate and concrete, to achieve the integrity of the steel plate and concrete. The steel plate can be used as a formwork for retaining concrete during construction, and can also be used as an attachment point for the grating railings, greatly improving construction efficiency. The edge protection railings are installed on the side steel plates, so that the area of the cloud bridge platform is fully utilized, avoiding the problem of the railings being installed on the platform surface and occupying the platform area. There is no need to widen the platform to meet the required platform width, thereby improving space utilization. In addition, the grating railings can be locally repaired, improving economic benefits.

In one possible implementation, the mounting base includes a U-shaped angle bracket, the bottom of which is fixedly connected to the side of the steel plate, and the grille railing can be inserted into the U-shaped bar bracket. The grille railing is connected to the U-shaped angle bracket via bolts. The bottom of the grille railing is provided with a first through hole 31, and the U-shaped angle bracket is provided with a second through hole 21 that extends through the two side plates. The bolt can simultaneously pass through the first through hole and the second through hole.
