Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a pier column rebar binding frame. Background Technology

[0002] In existing technologies, traditional bridge pier construction requires pre-embedding the pier reinforcement in the pier cap. After the pier cap is poured, scaffolding is erected for processes such as tying the pier reinforcement, setting up formwork, and pouring concrete. For irregularly shaped piers, all the stirrups of the pier must be pre-stacked before pre-embedding the reinforcement. This results in low construction efficiency and high construction costs. Traditional bridge pier construction suffers from technical problems such as requiring the pier cap to be poured before tying the pier reinforcement, leading to low construction efficiency and high costs. Utility Model Content

There are multiple support frames, and the working platform is installed on at least one side of each support frame. Each support frame includes a first transverse support and two sets of oppositely arranged side supports. The two ends of the first transverse support are slidably connected to the corresponding side supports, and the working platform is connected to the corresponding side supports.

[0005] Furthermore, each side support includes a column and an adjustment mechanism. The adjustment mechanism includes a rack, a gear, a drive assembly, and a connecting assembly. The rack is connected to the column, the gear meshes with the rack, the output end of the drive assembly is connected to the gear, the drive assembly is slidably connected to the column through the connecting assembly, the connecting assembly is connected to the corresponding end of the first transverse support, and the work platform is connected to the corresponding column.

[0006] Furthermore, the connecting component includes multiple limiting pulleys, which are symmetrically arranged on both sides of the driving component and slidably connected to the column.

[0007] Furthermore, each support frame also includes a bottom bracket and a fixed brace. The bottom bracket is connected to the column, and the two ends of the fixed brace are connected to the bottom bracket and the column, respectively.

[0008] Furthermore, the work platform includes a platform body and a protective railing connected to the platform body, with the platform body connected to the corresponding upright.

[0009] Furthermore, the support frame also includes a second transverse bracket, and the two ends of the second transverse bracket are detachably connected to the corresponding side brackets. Multiple first transverse brackets form a height-adjustable first steel reinforcement support surface, and multiple second transverse brackets form a second steel reinforcement support surface, with the first steel reinforcement support surface and the second steel reinforcement support surface being arranged opposite to each other.

[0010] Furthermore, the support frame also includes stabilizing legs, which are movably connected to the side supports to support the first or second lateral support.

[0011] The advantages and positive effects of this utility model are as follows: by adopting the above technical solution, the steel reinforcement cage can be prefabricated in advance to provide support for the positioning and binding of the pier column reinforcement, thereby improving construction efficiency.

[0025] The embodiments of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar units or units having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] In the description of this utility model, it should be understood that terms such as "installation", "connection", and "fixation" should be interpreted broadly, and can refer to direct connection, installation or fixation, or indirect connection, installation or fixation. This utility model does not limit this.

[0028] like Figures 1 to 5 The diagram illustrates an embodiment of a rebar tying frame for pier columns according to this utility model. It includes a working platform and a support frame. Multiple support frames are present, with a working platform installed on at least one side of each frame. Each support frame includes a first transverse support 3 and two sets of opposing side supports. The two ends of the first transverse support 3 are slidably connected to the corresponding side supports. The working platform is connected to the corresponding side supports, providing operating space for construction workers. In this embodiment, working platforms are installed on both sides of the support frame, and multiple side supports on each side are connected to the same working platform to form a continuous and interconnected working channel. Construction workers can walk on the working platform and tie the rebar erected on the support frame.

[0029] The main steps of the reinforcement binding construction method for pier columns are as follows:

[0030] S1. Fix the aforementioned pier column reinforcement binding frame to the construction area. Before or during the construction of the pier cap, begin the prefabrication and binding of the pier column reinforcement.

[0031] S2. Pier column reinforcement positioning and binding: Specifically, adjust the corresponding first transverse support 3 to the preset height, lay reinforcement 5 on multiple first transverse supports 3 to form a horizontal positioning benchmark, and bind the reinforcement 5 on the work platform to form the first construction surface of the reinforcement skeleton. Then, complete the reinforcement assembly and binding of the remaining construction surfaces of the reinforcement skeleton until a complete three-dimensional reinforcement skeleton is formed.

[0032] S3. Reinforcing steel cage transfer and cyclic construction: Specifically, after the reinforcement of the pier column is tied, the prefabricated reinforcing steel cage is lowered to the installation plane, and the reinforcing steel cage is transferred to the semi-finished product area for temporary storage using hoisting equipment, and then the prefabrication and tying of the reinforcing steel cage of the next pier column is carried out.

[0033] S4. Finished product hoisting and collaborative construction: Specifically, before the pier cap formwork assembly process, hoisting equipment is used to hoist the prefabricated pier column steel reinforcement cage into place.

[0034] This embodiment utilizes a pier column rebar binding jig to achieve three-dimensional positioning and multi-face binding of prefabricated rebar skeletons, avoiding the time-consuming traditional scaffolding erection and improving construction efficiency. The sliding connection of the first transverse support ensures adjustable rebar layer height, guarantees skeleton dimensional accuracy, and ensures precise control of construction quality. It also facilitates the descent of the prefabricated rebar skeleton onto the installation plane. Pier column rebar binding and foundation construction can be carried out in parallel, shortening the construction period and optimizing construction procedures. The pier column rebar binding jig is easy to assemble and disassemble, and can be reused, reducing the consumption of auxiliary materials and site occupation.

The multiple limiting pulleys 23 are symmetrically arranged to engage with both sides of the web plate of the column 6, ensuring the stability of the adjusting mechanism 2 sliding on the column 6.

[0038] In this embodiment, each support frame further includes a bottom bracket 9 and a fixed support 11. The bottom bracket 9 is connected to the column 6, and the two ends of the fixed support 11 are connected to the bottom bracket 9 and the column 6, respectively.

[0043] The pier reinforcement binding frame is fixed in the construction area. The lifting and lowering of the first transverse support 3 is adjusted by the control component 24, and all the first transverse supports 3 are adjusted to the same preset elevation.

The height of the first transverse support 3 is slidably adjusted to lower the prefabricated steel reinforcement skeleton to the installation plane. The prefabricated steel reinforcement skeleton is then transported for temporary storage.

[0048] This embodiment uses standardized dimensions for manufacturing, and the components can be detachably connected with bolts, making assembly convenient. After use, they can be disassembled for transportation or reuse.
