[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown, this utility model provides a prefabricated prestressed cap beam cantilever platform, including a supporting operating platform 1 and a protective frame plate 2. The supporting operating platform 1 has an installation groove 11 inside. The bottom of the protective frame plate 2 is fixedly connected to a welded base plate 23, which is welded inside the installation groove 11. The top of the protective frame plate 2 is fixedly connected to an installation seat 311, and the top of the installation seat 311 is hinged with an arc-shaped limit buckle 31. A reinforcing rod 3 is provided inside the arc-shaped limit buckle 31.

[0022] refer to Figure 1-3 The inner side of the support operating table 1 is provided with several welding side grooves 111. The welding side grooves 111 are connected to the mounting groove 11. The bottom of the welding base plate 23 is located below the bottom of the welding side grooves 111, and the inner edge of the welding side grooves 111 is welded to the side of the welding base plate 23 by welding strips.

[0023] Using the supporting operating platform 1 as the basic support platform for the entire cantilever platform, several protective frame plates 2 form the edge protection components of the entire cantilever platform at the top edge of the supporting operating platform 1. The reinforcing rod 3 and the protective frame plate 2 are fastened together by the arc-shaped limiting buckle 31 to form an integral unit. Several welding side grooves 111 are opened on the inner side of the supporting operating platform 1. The welding side groove 111 on one side of the mounting groove 11 is used to provide welding space between one side of the welding base plate 23 and one side of the mounting groove 11, so that the lower end area of ​​the welding base plate 23, which was originally inserted into the mounting groove 11, can be welded to the inner space of the welding side groove 111. The welded connection between the base plate 23 and the side wall of the support platform 1 helps to further improve the stability of the welded base plate 23 inside the mounting groove 11. This allows the entire cantilever platform's basic frame to be assembled with the cooperation of the support platform 1, protective frame plate 2, reinforcing rod 3, arc-shaped limit buckle 31, welded base plate 23, and mounting groove 11. On the one hand, this facilitates the transportation of parts by workers. On the other hand, it reduces the danger and difficulty of the entire protective assembly assembly due to the poor balance caused by the long workpiece during hoisting when the assembly is transported to a high place by cranes or other devices.

[0024] How to use

[0025] The working principle and usage process of this utility model are as follows: During construction, when a cantilever platform needs to be installed, the supporting operating platform 1 is first hoisted to the installation position using a hoisting tool. Then, a fixing rod is used to install the supporting operating platform 1 to the installation surface. After the supporting operating platform 1 is installed, the welding base plate 23 is inserted into the installation groove 11. A welding machine is then used to weld the welding base plate 23 to the installation groove 11, completing the initial fixation between the protective frame plate 2 and the supporting operating platform 1. Subsequently, the welding machine is used to weld one side of the welding base plate 23 to the inner edge of the welding side groove 111, completing the fixation between the protective frame plate 2 and the supporting operating platform 1. After completing one... After the protective frame plate 2 is installed and fixed to the supporting operating platform 1, the second protective frame plate 2 can be installed and fixed to the supporting operating platform 1. When installing the subsequent protective frame plates 2, the two adjacent protective frame plates 2 are placed and fixed together. After all the protective frame plates 2 are installed, the reinforcing rod 3 is fastened to the top of the protective frame plate 2 by the arc-shaped limiting buckle 31. After the initial limiting of the reinforcing rod 3 is completed, one end of the limiting steel cable 32 is fixed to one side of the protective frame plate 2. When installing the supporting operating platform 1 to the mounting surface, the connecting steel bar column 14, the reinforcing steel bar 13, and the pier column are fixed by the welding plate 141.
