In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0021] Example 1

[0022] like Figure 1-3 As shown, this embodiment provides a solid pier steel bar installation and binding operation platform, including a load-bearing frame 1 arranged above the outer formwork of a pier body of the solid pier, and an operating platform 2 connected to the top of the load-bearing frame 1, and a lifting ring 3 is arranged on the load-bearing frame 1;

[0023] The construction of solid piers adopts the mold turning process. When the next section of the pier is constructed, the outer mold of the previous section of the pier is usually not removed. Therefore, the load-bearing frame 1 in the utility model is placed on the outer mold of the previous section of the pier, and the construction workers stand on the operating platform 2 to install and tie the steel bars.

[0024] In some preferred embodiments, the height of the load-bearing frame 1 is consistent with the height of a single pier section, so that the steel bars at the top of the current pier section can be tied and the main bars of the next pier section can be installed at the same time. Therefore, in this type of embodiment, the main bars of the current pier section are also installed when the steel bars at the top of the previous pier section are tied.

[0025] Through the lifting ring 3, the working platform can be directly lifted and unloaded by a large crane, avoiding the construction of scaffolding at high altitude and improving the safety of construction.

[0026] In some preferred embodiments, the lifting rings 3 are evenly arranged on the radial outer surface of the same horizontal plane of the load-bearing frame 1, so that the working platform can stably pass through the main reinforcement that may exist above the outer mold during lifting, thereby achieving smooth installation.

[0027] The load-bearing skeleton 1 includes a plurality of vertical load-bearing members 4 arranged along the outer formwork of a pier body of an upper section of a solid pier, and a plurality of horizontal reinforcement rings 5 ​​are arranged at intervals outside the plurality of vertical load-bearing members 4 .

[0028] The material of the load-bearing frame 1 is not limited in the present invention, and it can be any one of angle steel, I-beam, square steel or round steel. Square steel is preferred in this embodiment. The specifications are also not limited in the present invention, and those skilled in the art can make reasonable settings according to the bearing capacity requirements.

[0029] A preferred operation process of the solid pier steel bar installation and binding operation platform of the utility model is:

[0030] After the solid pier reinforcement installation and tying work platform is completed on site or in the factory, a large crane is used to hoist it to the outer formwork of the previous pier body. After the connection is stable, the construction personnel are transported to the operating platform to tie the reinforcement of the pier body to be cast, and at the same time, the main reinforcement of the next pier body is installed, and the bottom of the main reinforcement is tied. When the installation and binding are completed, the solid pier reinforcement installation and tying work platform is removed by the crane again. During this period, care is taken to keep it stable and not to touch the main reinforcement of the next pier body. After removal, the outer formwork is installed on the pier body to be cast, and then concrete is poured. After the concrete has solidified for a period of time, the solid pier reinforcement installation and tying work platform is hoisted again to the outer formwork of the cast pier body, and the above steps are repeated to carry out the construction of the next pier body to be cast.

[0032] like Figure 1-3 As shown, this embodiment is carried out on the basis of embodiment 1, and the operating platform 2 includes an outer frame 6, and the outer frame 6 is connected to the load-bearing frame 1 through a crossbeam 7, and a table top 8 connected to the upper surface of the crossbeam 7 is laid between the outer frame 6 and the load-bearing frame 1.

[0033] The table top 8 is selected from any one of steel plate, alloy plate, wood plate, plastic plate or bamboo plywood, and bamboo plywood is preferred in this embodiment.

[0034] The present invention does not limit the material of the outer frame 6 and the cross beam 7, which may be any of angle steel, I-beam, square steel or round steel. Square steel is preferred in this embodiment. The present invention also does not limit the specifications, and those skilled in the art may make reasonable settings based on the bearing capacity requirements.
