Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of bridge manufacturing, and in particular, to a segmentation method, a segment, and a polygonal tower body for manufacturing a polygonal tower body. Background Art

[0002] Currently, with the continuous improvement of the urbanization level, urban steel bridge products are increasingly characterized by diverse cross-section forms, complex spatial angles, high requirements for manufacturing geometric dimension accuracy, and great manufacturing difficulty.

[0003] There are two traditional steel tower manufacturing segmentation methods: ① Horizontal segmentation of the actual bridge (e.g., the steel tower of Nanjing Fifth Bridge); ② Normal segmentation along the central axis (the steel tower of Nanjing Third Bridge). However, traditional steel tower manufacturing segmentation has obvious defects when dealing with steel towers with complex octagonal variable cross-section and spatial angle structures. If horizontal segmentation of the actual bridge is adopted, the section contour exceeds the limit, and the section needs to be divided into two blocks again from the middle for manufacturing, transportation, and installation. The number of manufactured sections increases, the workload at the bridge site increases, and it is not conducive to controlling the docking accuracy between the blocks at the bridge site. If normal segmentation along the central axis is adopted, the section contour dimensions meet the transportation requirements. Due to the large spatial angle between the diaphragm and the central axis, the diaphragms in the section will be spatially cut, and there is no complete diaphragm in each section. The self-stability of the section is extremely poor, and it is difficult to ensure the accurate installation and positioning of the diaphragms and the accurate docking of the diaphragms during the installation of the sections at the bridge site. Therefore, the two traditional segmentation schemes cannot be applied to the manufacturing of steel towers with complex octagonal variable cross-section and spatial angle structures.

[0004] Therefore, it is necessary to improve one or more problems existing in the above-mentioned related technical solutions.

[0005] It should be noted that this part is intended to provide background or context for the technical solutions of the present invention stated in the claims. The description herein is not admitted to be prior art merely because it is included in this part. Summary of the Invention

[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The features, structures, or characteristics described may be combined in any suitable manner in one or more embodiments.

[0039] In addition, the accompanying drawings are merely schematic illustrations of the embodiments of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted. Some of the block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0040] In this example embodiment, a segmentation method for manufacturing a polygonal tower body is first provided. Referring to Figure 1 as shown, it includes:

[0041] Step S101: Obtain the three-dimensional data of the polygonal tower body.

[0042] Step S102: Horizontally segment the polygonal tower body and obtain all the first segments.

[0043] Step S103: Segment the polygonal tower body in the normal direction and obtain all the second segments.

[0044] Step S104: Statistically analyze the contour geometric dimensions of the first segments and the second segments, as well as the integrity data of the partitions.

[0045] Step S105: Based on preset principles, comprehensively analyze the first segments and the second segments at the same positions and obtain all the third segments.

[0046] Among them, the preset principles include: ensuring that the contour geometric dimensions of the third segments meet the transportation conditions and ensuring the integrity of the partitions within the third segments.

[0047] It should be understood that the polygonal tower body can be a tower body on the bridge that is inclined both longitudinally and transversely along the bridge. The polygonal tower body can be a polygon with a changing cross-sectional space. Therefore, when the above method is used for segmenting polygonal tower bodies such as complex octagonal variable cross-section space-angle steel towers, its beneficial effects are more obvious. For example, in the case of the steel tower of Xianyang Bridge, the steel tower has a variable cross-section space-angle octagonal structure. The central axis of the steel tower is in space, with an included angle of 62.2° with the longitudinal projection along the bridge and an included angle of 76.8° with the transverse direction of the bridge. The axial length of the tower column is 87.445m, and the cross-section gradually changes from 5.2m×8.5m to 3.2m×4m. A diaphragm is arranged horizontally every 2m inside the steel tower. Therefore, the traditional segmentation method is completely inapplicable to complex polygonal tower bodies such as the steel tower of Xianyang Bridge. After the steel tower is manufactured in segments in the factory and transported to the bridge site by road for installation, due to transportation conditions, the maximum segmentation specification of the manufactured segments is: width 5m, height 4m. If horizontal segmentation of the actual bridge is adopted, the contour specification of the segment is width 5.2m, height 4m, and the width exceeds the limit. The segment needs to be transversely divided into two blocks again for separate manufacturing, transportation, and installation in the middle. The number of manufactured segments increases, the workload at the bridge site increases, and it is not conducive to controlling the docking accuracy between the blocks at the bridge site; if the normal segmentation method along the central axis is adopted, although the overall contour dimensions of the entire segment meet the transportation requirements, the diaphragms inside the segment will be cut by space, and there is no complete diaphragm in each segment. The self-stability of the segment is extremely poor, and it is difficult to ensure the accurate installation and positioning of the diaphragms and the accurate docking of the diaphragms during the installation of the segments at the bridge site.

[0048] It should also be understood that in its specific implementation process, the scheme is as follows: 1) The steel tower is modeled integrally in 3D using CATIA; 2) The steel tower segments adopt a horizontal segmentation scheme, and the geometric dimension data of the segment contour is statistically analyzed; 3) The steel tower segments adopt a normal segmentation scheme, the geometric dimension data of the segment contour is statistically analyzed, and the integrity of the diaphragms is analyzed; 4) The problems existing in the horizontal segmentation scheme and the normal segmentation scheme in this project are demonstrated respectively, and a horizontal and normal composite segmentation scheme is designed that can not only ensure that the overall contour geometric dimensions of the entire segment meet the transportation conditions but also ensure the integrity of the diaphragms; 5) The segments are divided and manufactured according to the horizontal and normal composite segmentation scheme.

[0049] It should also be understood that on the premise of meeting the transportability of the segment contour, the transverse secondary block division of the steel tower segments is avoided, and the number of segments is reduced by nearly half, greatly reducing the manufacturing, installation costs and construction period. There are two complete diaphragms in each segment, the self-stability of the segment is good, and the geometric accuracy control of the segment is guaranteed. The horizontal state of the diaphragms in the actual bridge is ensured, and the diaphragms can also serve as the permanent maintenance platform of the steel tower. There are no blocks that need to be longitudinally extended and widened transversely at the bridge site, the overall assembly and welding deformation of the segments are small, and both the manufacturing accuracy and the construction period are guaranteed. Compared with the normal segmentation scheme, when this scheme is adopted, the slope of the circumferential weld between the segments at the bridge site is smaller, the working conditions are better, and large slopes are avoided.

[0050] Through the above method, by simultaneously adopting horizontal and normal composite segmentation and analyzing the rationality of the obtained segments. Under the conditions of meeting the transportation requirements and the integrity of the diaphragms, the self-stability of the segments is good, there is no need to further divide the segments longitudinally, there is no longitudinal block docking, the number of segments is small, and both the manufacturing difficulty and efficiency can be greatly improved.

[0051] Next, reference will be made to Figures 1 to 6 to describe each step of the above segmentation method for manufacturing a polygonal tower body in the present exemplary embodiment in more detail.

[0052] In some embodiments, as shown in reference to Figures 2 to 3 in step S102, it includes:

[0053] Perform horizontal segmentation on the polygonal tower body along the bridge longitudinal direction of the polygonal tower body, and obtain all the first segments.

[0054] It should be understood that by performing horizontal segmentation on the polygonal tower body along the bridge longitudinal direction of the polygonal tower body, the obtained first segments can ensure that the diaphragms are not cut.

[0055] In some embodiments, as shown in reference to Figure 2 and Figure 4 in step S103, it includes:

[0056] Perform normal segmentation on the polygonal tower body along the bridge transverse direction of the polygonal tower body, and obtain all the second segments.

[0057] It should be understood that by performing normal segmentation on the polygonal tower body along the bridge transverse direction of the polygonal tower body, the width dimensions of each of the obtained second segments can be ensured to be basically the same.

[0058] In some embodiments, as shown in reference to Figures 2 to 5 in step S104, it includes:

[0059] Fuse the cross-sections of the first segments and the cross-sections of the second segments at the same position to form the cross-section of the third segments.

[0060] It should be understood that the cross-sections of the first segments and the cross-sections of the second segments can be mutually corrected to obtain the cross-section of the third segments. For example, the cross-section of the third segments is composed of the midpoints from the cross-section of the first segments to the cross-section of the second segments. Or perform weighted adjustment on the cross-section from the first segments to the second segments to obtain the cross-section of the third segments.

[0061] In some embodiments, as shown in reference to Figure 5 in step S104, it includes:

[0062] The preset principles include: ensuring that the width of the outline geometric dimensions of the third segment is ≤ 5 m and the height is ≤ 4 m to meet the transportation conditions.

[0063] It should be understood that due to transportation conditions, the maximum segment specification for manufacturing segments is: width 5 m, height 4 m. Therefore, after obtaining the third segment through composite segmentation using both horizontal and normal directions, the segmentation plan is further optimized and adjusted by comprehensively investigating the resource allocation situation in terms of manufacturing, transportation, and installation.

[0064] In some embodiments, as shown in Figure 5 in step S104, it includes:

[0065] The preset principles include: ensuring that there are two complete partitions within the third segment.

[0066] It should be understood that ensuring two complete partitions within each third segment can keep the segment itself in good stability. Therefore, after obtaining the third segment through composite segmentation using both horizontal and normal directions, the segmentation plan is further optimized and adjusted in terms of a small number of segment divisions, convenient manufacturing and installation, low manufacturing cost, guaranteed manufacturing quality, and good self-stability of the segment.

[0067] In some embodiments, as shown in Figure 6 in step S101, it includes:

[0068] Perform 3D modeling of the polygonal tower body through CATIA to obtain the 3D data of the polygonal tower body.

[0069] It should be understood that CATIA belongs to advanced hybrid modeling technology. It can help manufacturers design their future products through modeling and support the entire industrial design process from the pre-project stage, specific design, analysis, simulation, assembly to maintenance.

[0070] The present invention also provides a segment for manufacturing a polygonal tower body, obtaining the 3D data of the segment by using the segmentation method for the polygonal tower body in any one of the above embodiments; and building the entity of the segment. It should be understood that according to the 3D data of the segmented segments, the entity construction of each segment is completed according to the entity construction requirements of the polygonal tower body itself.
