Description

Technical Field

[0001] This invention relates to a variable-diameter vertical concrete tower reinforcement cage tooling and reinforcement binding method, belonging to the field of wind turbine generator concrete tower manufacturing. Background Technology

[0002] With the increasing size of wind turbine generators, concrete towers have become widely used due to their advantages such as good economy, high stiffness, and excellent damping characteristics. Concrete towers typically employ prefabricated segmented structures, with each segment being an arc-shaped structure, requiring internal reinforcement to form a three-dimensional steel cage. Traditional reinforcement cage tying methods mainly suffer from the following problems: Precision control is difficult: Mixed towers are typically truncated cone structures with a smaller top and a larger bottom, and the radial and circumferential dimensions of the reinforcing cage change continuously with height. Traditional methods of using fixed jigs or loose binding make it difficult to accurately control the outline dimensions of the reinforcing bars at each height, which can easily lead to large overall linear errors in the reinforcing cage, affecting subsequent mold closing and the thickness of the protective layer.

[0003] Low efficiency and high labor intensity: Loose ground binding requires a lot of manual measurement, positioning and support. The binding speed is slow, the area occupied is large, and workers need to bend over or climb for a long time, which is labor-intensive and poses safety hazards.

[0004] Poor adaptability: Fixed jigs or molds can usually only be used for tower sections of a single diameter. For mixed tower products of different diameters and different projects, tooling needs to be redesigned and manufactured, resulting in poor versatility and high cost.

[0005] Risk of deformation during hoisting of steel cages: Steel cages tied in the traditional way have uneven overall rigidity and are prone to twisting and deformation during hoisting to the mold, requiring secondary repair.

[0006] Therefore, there is a need for a rebar cage binding tool and method that can adapt to varying diameter requirements, ensure binding accuracy, improve work efficiency, reduce labor intensity, and has good versatility. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the present invention aims to provide a tooling and rebar binding method for a variable-diameter vertical mixed-tower rebar cage, which enables efficient and precise processing of rebar cages for mixed-tower cylinders of different diameters (equal diameter / gradually changing diameter) and heights, reduces equipment investment costs, and improves the processing stability and construction safety of high-tower cylinder rebar cages.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: According to a first aspect of the invention, a variable-diameter vertical mixed tower reinforcement cage tooling is provided, comprising a base assembly, a vertical support assembly, and a variable-diameter positioning assembly, wherein the vertical support assembly is mounted on the base assembly, and the variable-diameter positioning assembly is mounted on the vertical support assembly.

[0009] Furthermore, the base assembly includes a base, which is fixed to the hardened ground by a limiting pin, and six uprights are installed on the top of the base, which are fixed to the top of the base by pins.

[0010] Furthermore, the vertical support assembly includes adjustable diagonal braces and side rails. The two side rails are located on both sides of the base plate and are fixed on the hardened ground. The adjustable diagonal braces include radially adjustable diagonal braces and circumferentially adjustable diagonal braces. The circumferentially adjustable diagonal braces are connected between the side rails and the uprights, and the six radially adjustable diagonal braces are respectively connected between the six uprights and the base plate.

[0011] Furthermore, the top end of the radially adjustable brace is movably connected to the outer side surface of the column, and the bottom end of the radially adjustable brace is movably connected to the slide rail, which is fixedly installed on the base plate.

[0012] Furthermore, the top end of the circumferentially adjustable diagonal brace is movably connected to the outer side surface of the column, and the bottom end of the circumferentially adjustable diagonal brace is movably connected to the support. The support is fixedly installed on the side diagonal brace, and the side diagonal brace is fixedly installed on the side of the side track.

[0013] Furthermore, adjacent columns are connected and fixed by a horizontal tie rod.

[0014] Furthermore, the variable diameter positioning assembly includes a serrated groove fixedly installed on the outer surface of the column, a right-side positioning plate fixedly installed on the side of the column, and a top vertical rib positioning plate and a bottom template fixedly installed on the upper and lower sides of the column.

[0015] Furthermore, a circumferential main rib is horizontally fixed between the serrated groove and the right-side positioning plate, and several longitudinal distribution ribs are vertically installed on the outer side of the circumferential main rib. The longitudinal distribution ribs are positioned between the bottom template and the top vertical rib positioning plate.

[0016] Furthermore, the intersection of the circumferential main reinforcement and the longitudinal distribution reinforcement is fixed by binding wire.

[0017] According to a second aspect of the present invention, a method for binding reinforcing bars in a variable-diameter vertical mixed-tower steel cage fixture is provided, comprising the following steps: Construction workers used limit pins to install the base and side rails on the hardened ground, and fixed six columns on the base to form the base assembly; Based on the diameter of the tower steel cage, six radially adjustable diagonal braces are connected between the base frame and the column of the base frame assembly, and circumferentially adjustable diagonal braces are connected between the side rail of the base frame assembly and the column. Finally, horizontal tie rods are connected between two adjacent columns to form a vertical support assembly on the base frame assembly. A top vertical rib positioning plate, a bottom template, and a serrated groove are installed on the upper and lower sides of the column of the base tire assembly, and a right-side positioning plate is installed on the side of the column at the end, thereby forming a variable diameter positioning assembly on the base tire assembly. Place the circumferential main bars one by one into the sawtooth slots at the corresponding elevation positions to form a horizontal ring on the outside of the column. Then, install the longitudinal distribution bars along the outside or inside of the circumferential main bars according to the design spacing. The longitudinal bars are positioned and installed according to the bottom template and the top vertical bar positioning plate, and are fixed to the circumferential main bars by binding wire or automatic binding machine to form the main steel mesh. On the main steel mesh, tie the auxiliary steel bars such as hook bars and embedded part connecting bars to form a steel cage according to the drawings. After the binding is completed, the overall dimensions are checked. After verification, a crane and lifting equipment are used to transfer the steel cage into the tower formwork to complete the processing.

[0018] The beneficial effects of this invention are: This invention has a wide range of applications. It can achieve the processing of equal-diameter towers and gradually changing-diameter towers through adjustable structures such as slide rails and adjustable diagonal braces, adapting to the needs of different types of mixed towers. The tooling can be reused, reducing equipment investment costs.

[0019] This invention features high processing precision. Through the combined design of the bottom template, the top vertical reinforcement positioning plate, and the bidirectional support, it ensures that the longitudinal reinforcement spacing, the circumferential reinforcement spacing, and the verticality of the cage fully meet the first-level seismic and wind resistance design requirements of the mixed tower structure in the specifications.

[0020] This invention improves both construction efficiency and safety. The vertical processing method eliminates the need to flip the rebar cage. Through quick-release joints and a linked adjustment structure, a single person can complete the diameter / height adjustment, significantly increasing processing efficiency compared to traditional tooling. Furthermore, the base and bidirectional high-strength support structure ensure that the high-tower rebar cage is handled without shaking or slippage, reducing the construction safety accident rate to zero. Multiple fixing structures, including slide rails, bidirectional supports, and pins, enhance structural stability, minimizing lateral deflection and allowing the tooling to bear the weight of several tons of rebar cage, fully meeting the stability requirements for high-tower rebar cage processing.
