[0002] Traditional thin-walled hollow pier steel bar binding operation platforms mainly use temporary scaffolding built by hand. It is time-consuming and labor-intensive to build scaffolding. In actual construction, the turnover of large quantities of scaffolding brings more safety risks, especially in environments affected by typhoons, monsoons, and low temperatures. The working environment of workers is poor, the effective working time in the field is limited, the work efficiency is greatly reduced, the safety risks are multiplied, and the construction quality is difficult to control. Therefore, a new, stable, and safe built-in fully enclosed operation platform for thin-walled hollow piers is needed.

[0003] Prior art CN205894711U discloses a pier column movable steel bar binding bracket, including a frame body and a bottom plate, the frame body is fixed to the bottom plate, the bottom plate is bolted to the pier column flip formwork, the frame body is a ring structure surrounded by inner and outer layers of columns, a plurality of construction platforms are arranged between the inner and outer layers of columns, the construction platforms are spaced apart along the height direction of the inner and outer layers of columns, and vertical ladders are arranged between adjacent construction platforms. Compared with setting up scaffolding platforms, this prior art saves costs, improves construction efficiency, and ensures the safety of operators.

[0004] However, the operating area of ​​the tying bracket is still small, and a large amount of space inside the hollow pier is not effectively utilized. Utility Model Content

[0005] The purpose of the utility model is to provide a thin-walled hollow pier built-in operating platform to address the above shortcomings, thereby achieving the effects of expanding the operating space, improving safety, and improving installation and disassembly efficiency.

[0006] The purpose of the utility model is achieved in this way:

[0007] A thin-walled hollow pier built-in operating platform comprises a plurality of force-bearing frames arranged on the top of the inner mold of the hollow pier, wherein a main operating platform is arranged on the top of the force-bearing frames, and auxiliary operating platforms are arranged in the middle and the bottom respectively;

[0008] The main operating table comprises an outer frame connected to the plurality of force-bearing frames, and first main beams uniformly distributed in the inner space of the outer frame, and the inner space of the outer frame is paved with a main table top connected to the upper surface of the first main beam;

[0009] The auxiliary operating table includes a secondary outer frame and a secondary inner frame, the secondary outer frame is connected to the load-bearing frame, the secondary outer frame and the secondary inner frame are connected through a second main beam, and a secondary table surface connected to the upper surface of the second main beam is laid between the secondary outer frame and the secondary inner frame.

[0010] In certain embodiments, a main guardrail and a secondary guardrail are respectively disposed above the outer frame and the secondary inner frame.

[0011] In certain embodiments, diagonal braces are provided between the load-bearing skeleton and the first main beam and the second main beam, respectively.

[0012] In certain embodiments, the main table top or the auxiliary table top is selected from any one of a steel plate, an alloy plate, a wooden plate or a plastic plate.

[0013] The beneficial effects of the utility model are:

[0014] The utility model has a relatively simple structure and is more convenient to install and disassemble than a traditional scaffolding platform. At the same time, by arranging three operating tables from top to bottom, multiple groups of personnel can work at the same time, thereby improving the efficiency of tying steel bars. The area of ​​the main operating table is close to the internal area of ​​the hollow pier, thereby increasing the operating space for construction personnel, and some equipment and consumables that occupy a large space can be placed on the main operating table.

[0024] The force-bearing frame 1 is used to support the entire operating platform. The present invention does not limit the material thereof. In some preferred embodiments, the force-bearing frame 1 is made of No. 14 I-beam;

[0025] In some preferred embodiments, a limiting device is provided at the connection between the load-bearing frame 1 and the inner mold of the hollow pier, in order to prevent the load-bearing frame 1 from moving in position and thus causing danger.

[0026] As for the size of the operating platform, those skilled in the art can make reasonable adjustments according to the size of the hollow pier, and the present invention does not limit this. In some preferred embodiments, the distance between the main operating platform 2 and the auxiliary operating platform 3 in the middle is 1.8-2.2m, and the distance between the two auxiliary operating platforms 3 is 1.8-2.2m.
