[0011] According to a method for matching and manufacturing block - type steel bar components of a bridge pier provided by the present invention, in step S2, the method for tying the N - th block component in a horizontal state on the manufacturing station of the jig includes: laying the N - th main bars of the N - th block component along the horizontal longitudinal direction on the manufacturing pedestal, arranging spacer blocks between adjacent N - th main bars arranged together in the N - th block component, so that adjacent two N - th main bars arranged together are separated vertically.

[0012] According to a method for matching and manufacturing block - type steel bar components of a bridge pier provided by the present invention, perform an alternating arrangement process on adjacent N - th main bars arranged together in the N - th block component, so that the end of the N - th main bar extends longitudinally beyond the end of the adjacent N - th main bar by a set distance.

[0013] According to a method for matching and manufacturing block - type steel bar components of a bridge pier provided by the present invention, in step S3, the method for translating the tied N - th block component to the matching station of the jig includes: after the N - th block component is tied and formed, integrally lifting the N - th block component by a hoisting device, so that the weight of the N - th block component is transferred from the main - bar limiting structure to the hoisting device, removing the inner - layer supporting structure of the inner - layer main bars used to support the block component in the main - bar limiting structure, and then integrally lifting upward and translating the N - th block component along the horizontal longitudinal direction to the matching pedestal.

[0014] According to a method for matching and manufacturing block - type steel bar components of a bridge pier provided by the present invention, in step S3, the method for arranging the main bars of the (N + 1) - th block component in the horizontal direction on the manufacturing station includes: installing outer - cavity stirrups on the outer - layer supporting structure of the outer - layer main bars used to support the block component in the main - bar limiting structure, threading the outer - layer (N + 1) - th main bars of the (N + 1) - th block component arranged along the horizontal longitudinal direction into the outer - cavity stirrups based on the outer - layer supporting structure, installing an inner - layer supporting structure on the manufacturing pedestal, installing the inner - layer (N + 1) - th main bars of the (N + 1) - th block component on the inner - layer supporting structure, and then installing inner - cavity stirrups.

In step S4, the method for flipping the horizontally - stored N - th block component to a vertical state includes: after the N - th block component is bound and formed, installing lifting lugs at the upper and lower ends of the N - th block component respectively. One crane uses a frame lifting tool to connect the lifting lug at the upper end of the N - th block component, and one crane connects the lifting lug at the lower end of the steel bar component. The two cranes cooperate to lift the N - th block component until the N - th block component is flipped to a vertical state.

[0018] A method for matching and fabricating block - type steel bar components of a bridge pier according to the present invention. In step S2, the method for splitting a single - segment steel bar component into multiple block components according to the steel bar component structure includes: splitting the annular steel bar component into two block components symmetrically distributed with respect to the horizontal plane where the longitudinal center line is located.

[0019] The advantages of the present invention are as follows: 1. In the present invention, the binding and assembly of two - layer block components are carried out longitudinally along the horizontal direction in the jig. The adjacent two - layer block components will be pre - matched in the jig. The upper - segment block component in the jig is fabricated based on the lower - segment block component, that is, the main steel bars of the upper and lower two - segment block components are pre - positioned and pre - matched in advance. When actual assembly and installation are carried out, due to the pre - matching and positioning in advance, the main steel bars of the upper and lower two - segment block components can be quickly aligned and matched, and thus the alignment and assembly of the upper and lower two - segment block components can be quickly completed, greatly improving the installation efficiency of adjacent two - segment block components.

[0020] 2. The jig structure of the present invention is simple, including a fabrication pedestal and a matching pedestal fixed together longitudinally along the horizontal direction. The fabrication pedestal is used as a fabrication station for binding and fabricating block components, and the matching pedestal is used as a matching station for the completed block components and as a pre - matching basis for the block components to be fabricated at the fabrication station. The whole jig structure is simple, the installation and operation are convenient, and the continuous binding construction of this case can be efficiently realized.

[0021] 3. The present invention vertically separates the main reinforcement bars arranged together, facilitating the installation of threaded sleeves and avoiding the problem that the threaded sleeves cannot be installed due to the narrow position space where the main reinforcement bars are arranged together on the long side.

[0022] 4. The present invention arranges the main reinforcement bars arranged together in a staggered manner in the horizontal longitudinal direction, so that adjacent threaded sleeves will not interfere in the longitudinal direction, facilitating the arrangement and installation of the threaded sleeves.

[0023] 5. Before the formed block component is transferred from the manufacturing station to the matching station, the present invention lifts the block component by a hoisting device, and then removes the inner support structure inside the block component to avoid the inner support structure hindering the movement of the block component during the translation of the block component.

[0024] 6. When manufacturing the (N + 1)-th block component, first install the outer stirrups, then the outer main reinforcement bars, then install the inner support structure, and arrange the inner stirrups and inner main reinforcement bars. The entire arrangement method is orderly and relies on each other before and after, greatly improving the binding and manufacturing efficiency of the (N + 1)-th block component.

[0025] 7. The method for the present invention to dock and match the main reinforcement bars of the (N + 1)-th segment with those of the N-th segment is extremely simple. The main reinforcement bars of the (N + 1)-th segment are fixed to the end of the main reinforcement bars of the N-th segment through a threaded sleeve to complete the pre-matching of the main reinforcement bars of the (N + 1)-th segment with those of the N-th segment. Moreover, at this time, the main reinforcement bars of the (N + 1)-th segment and the main reinforcement bars of the N-th segment are fixedly connected in the longitudinal direction, and the binding and manufacturing of the (N + 1)-th block component can be conveniently carried out relying on the main reinforcement bars of the N-th segment.

[0026] 8. The method for the present invention to release the connection between the N-th block component and the (N + 1)-th block component is extremely simple. The threaded sleeve is screwed to the end of the main reinforcement bars of the N-th segment, and the threaded sleeve is located on the main reinforcement bars of the N-th segment, facilitating subsequent flipping and matching.

[0027] 9. The flipping of the block component by the present invention is extremely convenient. The transformation of the block component from the horizontal state to the vertical state can be completed by using two cranes. The operation process is extremely simple and the construction efficiency is extremely high.

[0028] 10. The present invention splits the steel bar component of a single segment into two block components, and the two block components are symmetrical to each other. The split block components have a simple structure and are convenient to manufacture. The subsequent assembly process is extremely simple, greatly improving the installation efficiency of the pier body steel bar components.

[0029] The manufacturing method of the present invention is extremely efficient, and pre-positioning and pre-matching are completed in the jig in advance. During the pier body assembly construction, it can greatly improve the assembly efficiency of adjacent two segments of steel bar components, improve the assembly accuracy, and has great popularization value.

Detailed Description of the Invention

[0038] The embodiments of the present invention will be described in detail below. The same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0040] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0041] Existing steel bar component forming is usually carried out separately under the tower and then hoisted as a whole onto the tower for docking with adjacent steel bar components. The assembly requires the main steel bars of the upper and lower adjacent sections of steel bar components to be accurately aligned vertically. Otherwise, the threaded sleeves connecting the vertically adjacent main steel bars cannot be screwed in to complete the docking. Since existing steel bar components are formed separately during the forming process and the main steel bars are only docked on the pier body, this mode results in that the vertically adjacent main steel bars usually cannot be accurately matched, the docking difficulty of the main steel bars of two sections of steel bar components is extremely high, and the assembly efficiency of steel bar components is extremely low.

[0042] To solve the above technical problems, the present application provides a method for matching and manufacturing block-type steel bar components of a bridge pier. By pre-positioning and pre-matching two adjacent sections of steel bar components during the manufacturing process of steel bar components, the main steel bars in two adjacent sections of steel bar components can be accurately matched before the pier body is assembled. When the pier body is installed and matched, the two adjacent sections of steel bar components can be quickly docked, greatly reducing the assembly difficulty of the two adjacent sections of steel bar components and improving the assembly efficiency.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] As Figures 1 to 7 , the method for matching and manufacturing block-type steel bar components of a bridge pier in this embodiment is carried out according to the following steps:

[0045] S1. Arrange the jig;

[0046] The jig in this embodiment includes two workstations. One is a manufacturing workstation for binding steel bar components, and the other is a matching workstation for pre-matching and pre-positioning two adjacent sections of steel bar components. The two workstations in this embodiment are arranged adjacently along the horizontal longitudinal direction (the longitudinal direction in this embodiment refers to Figure 1 the up and down direction in Figure 1 the left and right direction in Figure 1 is the vertical direction, and the direction perpendicular to the paper surface in

[0047] S2. Split a single segment of steel bar component into multiple sub-components according to the structure of the steel bar component, and bind the Nth sub-component in a horizontal state on the manufacturing workstation of the jig;

[0048] The structure of the steel bar component is obtained according to the requirements of the pier structure. To facilitate the fabrication of the steel bar component within the jig, the steel bar component of a single segment can be split into multiple sub-components. Finally, when assembling and installing on the pier, the multiple sub-components are assembled and connected to form a complete steel bar component;

[0049] Bind the Nth sub-component on the fabrication station of the jig. The Nth sub-component being bound is in a horizontally lying state.

[0050] S3. Translate the completely bound Nth sub-component to the matching station of the jig. Arrange the main steel bars of the (N + 1)th sub-component horizontally on the fabrication station, align the end parts of the main steel bars of the (N + 1)th sub-component with those of the Nth sub-component along the horizontal longitudinal direction, and connect the butt-jointed main steel bars together through a threaded sleeve for pre-matching. Then bind and fabricate the (N + 1)th sub-component;

[0051] The (N + 1)th sub-component is fabricated based on the Nth sub-component. When binding the Nth sub-component, the Nth sub-component is at the adjacent matching station. Arrange the main steel bars of the (N + 1)th sub-component that are butt-jointed with the Nth main steel bars on the fabrication station. That is, during the fabrication of the (N + 1)th sub-component, the main steel bars of the Nth sub-component and the (N + 1)th sub-component are pre-positioned and pre-matched in advance. The (N + 1)th sub-component is constructed by binding based on the already pre-matched main steel bars of the (N + 1)th sub-component.

[0052] S4. Disconnect the connection between the Nth sub-component and the (N + 1)th sub-component. Translate the Nth sub-component to the stacking area, turn the horizontally stored Nth sub-component to the vertical state, hoist it onto the tower for butt-joint with the already installed steel bar component, and then connect multiple Nth sub-components together to form the Nth steel bar component;

[0053] The sub-components formed on the jig are in a horizontally lying state. Before assembling on the tower, the horizontally lying sub-components need to be turned to the vertical state so that they can be hoisted onto the tower for installation;

[0054] The sub-components in this embodiment are hoisted onto the pier step by step. After completing the connection with the already installed steel bar component, they are then connected to each other to form the steel bar component of this segment. The construction process is in good order and highly efficient.

[0055] S5. Translate the (N + 1)th sub-component to the matching station, and bind the (N + 2)th sub-component on the fabrication station based on the (N + 1)th sub-component according to the above steps, and so on until all the steel bar components are fabricated.

[0056] In this embodiment, two sections of block components are tied and assembled longitudinally along the horizontal direction within the jig. The adjacent two sections of block components are pre-matched within the jig. The upper-section block components within the jig are fabricated by tying based on the lower-section block components, that is, the main bars of the upper and lower sections of block components are pre-positioned and matched in advance. When actual assembly and installation are carried out, due to the pre-matching and positioning, the main bars of the upper and lower sections of block components can be quickly aligned and matched, and thus the alignment and assembly of the upper and lower sections of block components can be quickly completed, greatly improving the installation efficiency of the adjacent two sections of block components.

[0057] In some other embodiments of the present application, the layout method of the jig is optimized. Specifically, as Figures 1 to 4 shown, the jig of this embodiment includes a fabrication pedestal 1 and a matching pedestal 2. The fabrication pedestal 1 and the matching pedestal 2 are flat base structures. A plurality of adjusting bases 3 are installed at the bottoms of the fabrication pedestal 1 and the matching pedestal 2. The adjusting bases 3 are vertical adjusting structures capable of height adjustment, and are used for leveling the fabrication pedestal 1 and the matching pedestal 2 to ensure the accuracy of the forming of the steel bar components.

[0058] A main bar limiting structure is provided on the fabrication pedestal 1. The main bar limiting structure includes an inner supporting structure and an outer supporting structure. The inner supporting structure is used to support the main bars inside the block components, and the outer supporting structure is used to support the main bars outside the block components. As Figures 1 to 3 shown, the outer supporting structure includes outer main bar brackets 4 located on the transverse two sides of the fabrication pedestal 1. The outer main bar brackets 4 are truss structures arranged along the transverse direction. A plurality of square steels arranged along the horizontal transverse direction are provided on the outer main bar brackets 4. The plurality of square steels are arranged at intervals in the vertical direction. An outer main bar support rod 5 that can be pulled and moved horizontally along the transverse direction is inserted into the square steels of the outer main bar brackets 4. One end of the outer main bar support rod 5 penetrates into the square steels of the outer main bar brackets 4, and the other end extends towards the center of the fabrication pedestal 1 along the horizontal transverse direction. A limiting groove for placing the outer main bars is provided at the upper end of the side where the outer main bar support rod 5 extends towards the fabrication pedestal 1.

[0059] The outer supporting structure further includes outer transverse support rods 6 located in the middle of the fabrication pedestal 1. A plurality of outer transverse support rods 6 are arranged at intervals in the longitudinal direction. The outer transverse support rods 6 themselves are fixed on the fabrication pedestal 1 along the horizontal transverse direction. A plurality of groups of limiting short rods 7 are installed on the outer transverse support rods 6. The plurality of groups of limiting short rods 7 are arranged at intervals in the horizontal transverse direction. Each group of limiting short rods 7 includes two limiting short rods 7 arranged at intervals in the transverse direction. The lower ends of the limiting short rods 7 are fixed on the outer transverse support rods 6, and the upper ends extend vertically. The outer main bars on the long side of the block components are placed between the two limiting short rods 7 in the same group. As Figures 2 to 3 shown, two outer main bars are placed between each group of limiting short rods 7 in this embodiment, and the two outer main bars are stacked and arranged vertically.

[0060] The inner support structure includes inner main reinforcement brackets 8 arranged on both sides of the production pedestal 1. The inner main reinforcement brackets 8 are located inside the outer main reinforcement brackets 4. The outer main reinforcement brackets 4 on the same side as the production pedestal 1 are arranged at intervals in the transverse direction. The two are fixedly connected into one body through a transverse connecting rod to form a set of side main reinforcement support structures. On one transverse side of the production pedestal 1, multiple sets of side main reinforcement support structures are arranged at intervals in the longitudinal direction. The two sets of side main reinforcement support structures at the longitudinal two ends are connected into one body with the adjacent set of side main reinforcement support structures respectively, for supporting the ends of the main reinforcement. The connection method is that the outer main reinforcement brackets 4 of the outer support structure in the side main reinforcement support structure are connected together.

[0061] Similarly, multiple inner main reinforcement support rods 9 are arranged on the inner main reinforcement brackets 8 at intervals in the vertical direction. The multiple inner main reinforcement support rods extend away from the center of the production pedestal 1 at one end. The upper end surface of the cantilever end of the inner main reinforcement support rod 9 is also provided with a limiting groove for placing the inner main reinforcement. In this embodiment, there are multiple sets of outer main reinforcement brackets 4 and inner main reinforcement brackets 8, which are arranged at intervals in the longitudinal direction.

[0062] The inner support structure of this embodiment further includes multiple vertical support rods 10 arranged at intervals in the transverse direction in the middle of the production pedestal 1. The lower ends of the vertical support rods 10 are installed on the production pedestal 1, and the upper ends extend vertically. The upper ends of the vertical support rods 10 are installed with inner transverse support rods 11 arranged horizontally in the transverse direction. The multiple inner transverse support rods 11 are arranged at intervals in the longitudinal direction. Drag ropes 12 are arranged at both ends of the inner transverse support rods 11, and the inner transverse support rods 11 can be pulled out of the production pedestal 1 through the drag ropes 12.

[0063] In this embodiment, the connections between the outer main reinforcement brackets 4, outer main reinforcement support rods 5, outer transverse support rods 6, limiting short rods 7, inner main reinforcement brackets 8, inner main reinforcement support rods 9, vertical support rods 10, inner transverse supports 11 and between them and the production pedestal 1 are all connected through detachable pin structures, which is convenient for disassembly and assembly.

[0064] In addition, it also includes multiple outer cavity stirrup positioning rods 13 arranged at intervals in the vertical direction. The outer cavity stirrup positioning rods 13 are rod structures arranged horizontally in the longitudinal direction on the outer main reinforcement brackets 4. Multiple positioning grooves are opened on the outer cavity stirrup positioning rods 13 for positioning the outer cavity stirrups so that the outer cavity stirrups are arranged at a set spacing.

[0065] Component limiting structures are installed on the matching pedestal 2, such as Figure 1 and 4 shown. The component limiting structures include component limiting frames 14 respectively arranged on the two transverse sides of the matching pedestal 2. The component limiting frames 14 are used to limit the transverse movement of the segmented components.

[0066] In some embodiments of the present application, the method of tying the Nth segmented part in a horizontal state at the fabrication station of the jig is optimized. The Nth main reinforcement of the Nth segmented part is arranged horizontally and longitudinally on the fabrication pedestal 1. Specifically, after installing the main reinforcement limiting structure on the fabrication pedestal 1, the Nth main reinforcement is placed horizontally and longitudinally on the outer main reinforcement support rod 5, the inner main reinforcement support rod 9, the inner transverse support rod 11, and the limiting short rod 7. The main reinforcement within the limiting short rod 7 is arranged in two rows. To facilitate the subsequent installation of the threaded sleeve at the end of the main reinforcement, when arranging two rows or multiple rows of main reinforcement between the limiting short rods 7 in this embodiment, spacers are provided between adjacent main reinforcements to separate them. A Φ6 steel bar can be placed between adjacent main reinforcements for separation.

[0067] Similarly, when there are multiple rows of other main reinforcements in the segmented part, the same method is used for separation.

[0068] In some other embodiments of the present application, the arrangement of the main reinforcement is optimized. For example, when tying the Nth segmented part, the long side of the Nth segmented part is arranged with two rows of the Nth main reinforcement. The superposition arrangement of two rows of the Nth main reinforcement is not convenient for installing the threaded sleeve. Therefore, in this embodiment, the adjacent Nth main reinforcements among the multiple rows of the Nth main reinforcement are arranged in a staggered manner in the longitudinal direction. The adjacent Nth main reinforcements arranged together in the Nth segmented part are processed in a staggered arrangement, so that the end of the Nth main reinforcement extends longitudinally beyond the end of the adjacent Nth main reinforcement in the same row by a set distance. The set distance in this embodiment is 1.12 m. The staggered arrangement method provides sufficient space for installing the threaded sleeve at the ends of the main reinforcements in the same row.

[0069] In a further embodiment of the present application, the method of translating the tied Nth segmented part to the matching station of the jig in the above step S3 is optimized. After the Nth segmented part is tied and formed, the Nth segmented part 3 is lifted as a whole by 3 mm by a hoisting device, so that the weight of the Nth segmented part is transferred from the main reinforcement limiting structure to the hoisting device. The inner support structure of the inner main reinforcement for supporting the segmented part in the main reinforcement limiting structure is disassembled and withdrawn, and then it is lifted upward as a whole and translated horizontally and longitudinally to the matching pedestal.

[0070] Actually, after transferring the weight of the Nth segment sub-component to the hoisting equipment, the structures in the main reinforcement limiting structure that affect the translation of the Nth segment sub-component are removed. The removed structures include the inner main reinforcement bracket 8, the inner main reinforcement support rod 9, and the inner horizontal support rod 11. The removal sequence is as follows: first, the Nth segment sub-component is lifted as a whole by 3 mm by the hoisting equipment, and the inner horizontal support rod 11 is pulled out from the side of the Nth segment sub-component by using the drag rope 12, and then the inner main reinforcement bracket 8 and the inner main reinforcement support rod 9 are removed. The outer main reinforcement support rod 5 is a structure that can be pulled out horizontally. By pulling it out horizontally outward, the outer main reinforcement support rod 5 is disengaged from the Nth segment sub-component. At this time, the only structure on the entire production pedestal 1 that affects the movement of the Nth segment sub-component is the vertical support rod 10. The hoisting equipment lifts the Nth segment sub-component as a whole so that the Nth segment sub-component exceeds the upper end of the vertical support rod 10, and then it is translated longitudinally as a whole onto the matching pedestal 2.

[0071] In some other embodiments of the present application, the method of arranging the main reinforcement of the (N + 1)th segment sub-component horizontally at the production station in step S3 above is optimized. After the Nth segment sub-component is transferred to the matching pedestal 2, the binding and production of the (N + 1)th segment sub-component can be carried out on the production pedestal 1. At this time, the inner support structures on the production pedestal 1 have all been removed, and only the outer support structures remain. First, install the outer cavity stirrups on the outer support structure, and pass the outer (N + 1)th main reinforcement of the (N + 1)th segment sub-component arranged horizontally longitudinally through the outer cavity stirrups based on the outer main reinforcement support rod 5 and the limiting short rod 7. Reinstall the inner support structures on the production pedestal 1, including the inner main reinforcement bracket 8, the inner main reinforcement support rod 9, the vertical support rod 10, the inner horizontal support rod 11, and the drag rope 12. Then install the inner (N + 1)th main reinforcement of the (N + 1)th segment sub-component on the inner main reinforcement support rod 9 and the inner horizontal support rod 11, and then install the inner cavity stirrups, and install other stirrups and hook bars to complete the binding and forming of the (N + 1)th segment sub-component.

[0072] In some embodiments of the present application, the method of pre-matching the butt-jointed main reinforcements by means of a threaded sleeve is optimized. The main reinforcements in this embodiment are all thread-rolled before arrangement. One end of the main reinforcement is rolled with a long thread (the long thread is the same length as the threaded sleeve), and the other end is rolled with a short thread (the length of the short thread is half of the length of the threaded sleeve). The upper end of the main reinforcement (referring to the upper end after being flipped to the vertical state, actually the right end in Figure 5 is the long thread, and the lower end (referring to the lower end after being flipped to the vertical state, actually the left end in Figure 5 is the short thread).

[0073] The end of the Nth main reinforcement of the Nth segment block component is sleeved with a threaded sleeve (located at one end of the long filament of the Nth main reinforcement), and the end of the threaded sleeve protrudes from the end of the Nth main reinforcement by 3 threads. The threaded sleeve moves as a whole to the matching base 2 with the Nth segment block component. When docking the N+1th main reinforcement of the N+1th segment block component, the end of the N+1th main reinforcement is inserted into the corresponding threaded sleeve and then tightened until it cannot be twisted, which is equivalent to completing the pre-matching of the N+1th main reinforcement and the Nth main reinforcement. The N+1th main reinforcement is fixed to the Nth main reinforcement through the threaded sleeve.

[0074] In a further embodiment of the present application, the method for releasing the connection between the Nth segment block component and the N+1th segment block component in the above step S4 is optimized. The outer cavity stirrups are arranged on the outer cavity stirrup positioning rod 13, and the N+1th segment main reinforcement is inserted into the outer cavity stirrups. After the pre-matching of the N+1th segment main reinforcement and the Nth segment main reinforcement is completed, the position where the N+1th segment main reinforcement contacts the outer cavity stirrups is welded and fixed, which is equivalent to completing the fixation of the N+1th segment main reinforcement. After the N+1th segment main reinforcement is fixed, the threaded sleeve can be screwed onto the Nth segment main reinforcement to release the connection between the N+1th segment main reinforcement and the Nth segment main reinforcement. Similarly, the same method is used to release the installation of the inner layer N+1th segment main reinforcement of the N+1th segment block component. After the N+1th segment main reinforcement is connected to the Nth segment main reinforcement, the inner layer stirrups are installed, and the N+1th segment main reinforcement is welded and fixed to the inner layer stirrups, and then the connection between the N+1th segment main reinforcement and the threaded sleeve is released.

[0075] In some other embodiments of the present application, the method of flipping the horizontally stored N-th segment block component to a vertical state in the above-mentioned step S4 is optimized. After the N-th segment block component is tied and formed, lifting ears are installed at the upper and lower ends of the N-th segment block component respectively, and 8 lifting ears are installed at the upper end of the N-th segment block component, and 2 lifting ears are installed at the lower end of the N-th segment block component. A crane uses a frame sling to connect the 8 lifting ears at the upper end of the N-th segment block component, and a crane connects the 2 lifting ears at the lower end of the steel bar component. The two cranes slowly lift and lift the N-th segment block component by about 1.5m. The crane hoisting the top of the N-th segment block component hoists the N-th segment block component and slowly rises. The crane hoisting the bottom of the N-th segment block component hoists the N-th segment block component and slowly descends, turning the N-th segment block component over and erecting it, as shown in FIG. Figure 6 shown.

[0076] In some optimized embodiments of the present application, the method of splitting a single segment of a steel bar component into multiple sub-components according to the steel bar component structure in the above step S2 is optimized. Figure 7As shown in the figure, in this embodiment, the ring-shaped steel bar component is split into two sub-components symmetrically distributed with respect to the horizontal plane centered on the longitudinal center line. The two sub-components are symmetrical to each other and are fabricated in two halves. The structure is simple and the fabrication is convenient. Finally, they are assembled and formed on the pier body, and the construction efficiency is extremely high. In actual application, it is not limited to this distribution method. As long as it can meet the requirements of equal division and convenient fabrication, it falls within the protection scope of this case.

[0077] The specific fabrication method is carried out according to the following steps:

[0078] Step 1: Arrange the formwork support. Install the fabrication pedestal 1 and the matching pedestal 2 on the concrete ground. A plurality of leveling bases 3 are provided below the fabrication pedestal 1 and the matching pedestal 2. The leveling bases 3 can adjust the vertical height to level the fabrication pedestal 1 and the matching pedestal 2.

[0079] The fabrication pedestal 1 and the matching pedestal 2 are arranged adjacent to each other along the horizontal longitudinal direction. An element limiting frame 14 is installed on the matching pedestal 2. A main bar limiting structure is installed on the fabrication pedestal 1, including outer main bar supports 4 on both sides. A drawable outer main bar support rod 5 is installed on the outer main bar support 4. Inner main bar supports 8 are arranged inside the outer main bar supports 4. Inner main bar support rods 9 are installed on the inner main bar supports 8. A plurality of vertical support rods 10 are installed at the middle position of the fabrication pedestal 1. Inner horizontal support rods 11 are arranged at the upper ends of the vertical support rods 10. Drag ropes 12 at both ends of the inner horizontal support rods 11 extend out of the fabrication pedestal 1. A plurality of outer horizontal support rods 6 are arranged on the upper surface of the fabrication pedestal 1. A plurality of groups of limiting short rods 7 are arranged on the outer horizontal support rods 6.

[0080] A side main bar support structure formed by a group of outer main bar supports 4 and inner main bar supports 8 is also installed at both ends of each side of the fabrication pedestal 1 in the transverse direction. The side main bar support structure is used to support the ends of the main bars of the sub-components.

[0081] A plurality of outer cavity stirrup positioning rods 13 are installed on the outer main bar supports 4 on both sides of the fabrication pedestal 1 in the transverse direction and are arranged at intervals along the vertical direction.

[0082] Step 2: According to the structure of each section of the steel bar component, the ring-shaped steel bar component is evenly divided into two sub-components. The two groups of sub-components are symmetrically arranged. Each time, a group of sub-components is fabricated on the fabrication pedestal 1.

[0083] Taking the sub-component of the Nth section of the steel bar component as an example, that is, the Nth section of the sub-component, when binding the Nth section of the sub-component:

[0084] Arrange the outer cavity stirrups according to the outer cavity stirrup positioning rod 13. Thread the ends of the main reinforcement bars of the Nth segmented component, i.e., the two ends of the Nth main reinforcement bars. Then, place them on the outer main reinforcement support rods 5 and the inner main reinforcement support rods 9 according to the set arrangement pattern. The Nth layer of main reinforcement bars passes through the already fixed outer cavity stirrups.

[0085] Then, arrange the Nth main reinforcement bars on the inner horizontal support rods 11 and the outer horizontal support rods 6. The Nth main reinforcement bars in this part are directly placed into the limit short rods 7 on the inner horizontal support rods 11 and the outer horizontal support rods 6. Among them, the main reinforcement bars on the outer horizontal support rods 6 are in double rows, so separation treatment is required. Place a Φ6 steel bar between the two Nth main reinforcement bars between the same group of limit short rods 7 to separate the two Nth main reinforcement bars in the vertical direction. In addition, the two Nth main reinforcement bars between the same group of limit short rods 7 also need to be staggered. Extend one of the Nth main reinforcement bars between the same group of limit short rods 7 longitudinally, and keep the other unchanged, so that the two Nth main reinforcement bars in the same group are staggered by 1.12 m in the longitudinal direction. Then, sleeve a threaded sleeve on the long-thread end of the Nth main reinforcement bar (i.e., the end connected to the (N + 1)th segmented component).

[0086] Then, install the inner cavity stirrups. The inner cavity stirrups are attached to the outer cavity stirrups. Install the diagonal stirrups. The diagonal stirrups are attached to the outer cavity stirrups. Install the hook bars to form the Nth segmented component.

[0087] Finally, install 8 lifting lugs at the upper end of the Nth segmented component (the upper end after being flipped to the vertical state), and install 2 lifting lugs at the lower end of the Nth segmented component (the lower end after being flipped to the vertical state).

[0088] Step 3: The Nth segmented component needs to be transported to the matching pedestal 2. First, vertically lift the Nth segmented component by 3 mm through the hoisting equipment, so that the weight of the Nth segmented component is completely transferred to the hoisting equipment. Pull out the inner horizontal support rod 11 from the Nth segmented component through the dragging rope 12, remove the inner main reinforcement bracket 8 and the inner main reinforcement support rod 9, then pull out the outer main reinforcement support rod 5 outward. Finally, vertically lift the Nth segmented component through the hoisting equipment until the lower end of the Nth segmented component exceeds the upper end of the vertical support rod 10. At this time, there is no structure on the production pedestal 1 that hinders the movement of the Nth segmented component. The hoisting equipment hoists and transports the Nth segmented component horizontally to the matching pedestal 2, and lowers the Nth segmented component between the two groups of component limit frames 14.

[0089] Based on the Nth segmented component, the binding and fabrication of the (N + 1)th segmented component are carried out. At this time, on the fabrication pedestal 1, there are still the outer main reinforcement brackets 4, the outer cavity stirrup positioning rods 13, and the outer horizontal support rods 6 left. Push the outer main reinforcement support rod 5 inward, arrange the outer cavity stirrups on the outer cavity stirrup positioning rods 13, and then arrange the (N + 1)th main reinforcements of the outer layer on the outer main reinforcement support rod 5 and the outer horizontal support rod 6. Insert the end of the (N + 1)th main reinforcement into the threaded sleeve at the end of the Nth main reinforcement, and tighten until it can no longer be turned. Then, weld and fix the position where the (N + 1)th main reinforcement contacts the outer cavity stirrups, turn the threaded sleeve, screw the threaded sleeve onto the Nth main reinforcement, and release the connection between the (N + 1)th main reinforcement and the Nth main reinforcement;

[0090] Build the inner main reinforcement brackets 8, the inner main reinforcement support rods 9, and the inner horizontal support rods 11 on the fabrication pedestal 1. Then, arrange the (N + 1)th main reinforcements of the inner layer on the inner main reinforcement support rod 9 and the inner horizontal support rod 11. The connection method of the threaded sleeve is the same as that of the outer (N + 1)th main reinforcement above;

[0091] Install the inner cavity stirrups, the inner cavity stirrups fit with the outer cavity stirrups. Install the diagonal stirrups, the diagonal stirrups fit with the outer cavity stirrups. Install the hook bars to form the (N + 1)th segmented component.

[0092] Step Four: Use the hoisting equipment to lift the Nth segmented component to a certain height, and then translate it as a whole to the stacking place. One crane connects multiple lifting lugs at the upper end of the Nth segmented component using a frame lifting tool, and one crane connects multiple lifting lugs at the lower end of the steel bar component. The two cranes slowly lift, lift the Nth segmented component to a certain height, exceeding the top of the jig. The crane hoisting the top of the Nth segmented component hoists the Nth segmented component slowly upward, and the crane hoisting the bottom of the Nth segmented component hoists the Nth segmented component slowly downward to turn the Nth segmented component over and erect it;

[0093] Hoist it onto the tower and dock it with the previously installed (N - 1)th steel bar component. Hoist the Nth segmented component to the corresponding matching position, align the main reinforcements of the Nth segmented component with those of the (N - 1)th segmented component, and stably connect all the butt - joint main reinforcements using threaded sleeves. Diagonally tension the inner cavity of the Nth segmented component with wind - proof ropes to fix the Nth segmented component. When the installation of the two Nth segmented components is completed, lap the two Nth segmented components according to the specifications, install the remaining loose - bound stirrups and hook bars, and then remove the wind - proof ropes.

[0094] Step Five: According to the above steps, hoist the (N + 1)th segmented component to the matching pedestal 2, and then carry out the binding and fabrication of the (N + 2)th segmented component. Proceed in sequence until the binding of all the steel bar components is completed.
