Description

Technical Field

[0001] This application relates to the field of bridge engineering, specifically to an automated method and equipment for determining the reinforcement of variable cross-section bridge towers. Background Technology

[0002] Currently, bridge towers are key load-bearing components of long-span bridge structures such as cable-stayed bridges and suspension bridges. Their stress performance directly affects the safety and durability of the entire bridge. To meet the structural stress and construction requirements, towers are usually equipped with a large number of longitudinal and transverse steel bars. The longitudinal steel bars are arranged along the inner contour line of the tower to bear complex stress states such as local bending and temperature shrinkage.

[0003] In related technologies, the geometry of bridge towers is often highly irregular. Their cross-sectional dimensions change continuously along the height due to structural stress requirements, often exhibiting geometric features such as thickened inner walls, indentation, or angles. For example, the bottom of the tower is designed with a larger cross-section to bear greater loads and gradually tapers upwards; the connection between the tower and the beam requires local thickening due to stress concentration; and the top of the tower forms an angle due to structural transition. The longitudinal reinforcement inside the tower mainly relies on manual experience for installation. Due to the frequent changes in the cross-section of the tower and the complex geometric relationships in the transition area, it is difficult for humans to capture the reinforcement positioning information of each control section. To avoid the risk of insufficient reinforcement, the same shape and quantity of reinforcement are usually continuously laid out according to the maximum cross-sectional size. Although this can ensure structural safety, it is very easy to cause redundancy in the amount of reinforcement used, increasing material costs.

[0004] Therefore, it is necessary to design an automated method for determining the reinforcement of variable cross-section bridge towers to overcome the above problems. Summary of the Invention

Within a certain longitudinal reinforcement layout zone, all longitudinal discontinuous reinforcement is arranged, and the longitudinal discontinuous reinforcement is arranged symmetrically about the centerline of the control boundary of the longitudinal reinforcement layout zone. Among them, the size of the longitudinal reinforcement arrangement zone with longitudinal continuous reinforcement and longitudinal discontinuous reinforcement is larger than the size of the longitudinal reinforcement arrangement zone with all longitudinal continuous reinforcement, and the size of the longitudinal reinforcement arrangement zone with longitudinal continuous reinforcement and longitudinal discontinuous reinforcement is larger than the size of the longitudinal reinforcement arrangement zone with all longitudinal discontinuous reinforcement.

[0011] In conjunction with the first aspect, in one embodiment, the longitudinal continuous reinforcing bars are parallel to the control boundary of the longitudinal reinforcing bars on their adjacent sides, and the longitudinal discontinuous reinforcing bars are parallel to the centerline of the control boundary of the longitudinal reinforcing bar arrangement zone in which they are located.

[0012] In conjunction with the first aspect, in one embodiment, the longitudinal discontinuous reinforcing bar is broken at the location where it intersects with the longitudinal continuous reinforcing bar.

Usually, the same shape and quantity of reinforcement are continuously arranged according to the maximum cross-sectional size, which, although ensuring structural safety, easily leads to redundant reinforcement usage and increases material costs.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0020] This application provides an automated method and equipment for determining the reinforcement of variable cross-section bridge towers. It can solve the technical problem that the longitudinal reinforcement in the tower column mainly relies on manual experience to build. Usually, the same shape and quantity of reinforcement are continuously laid out according to the maximum cross-sectional size. Although this can ensure structural safety, it is very easy to cause redundancy in the amount of reinforcement and increase material costs.

[0021] See Figure 1 As shown in the figure, this application provides an automated method for determining the reinforcement of a variable cross-section bridge tower, which includes: S1: Read the 3D model of the bridge tower structure and divide the tower column into different sections from bottom to top based on the thickening and recess position of the inner wall of the tower column.

[0022] S2: Generate the corresponding control section 1 and longitudinal reinforcement control boundary 2 for each section.

[0023] S3: Based on the control section 1 and longitudinal reinforcement control boundary 2 of each section, the longitudinal reinforcement arrangement area 3 of the control section 1 of each section is divided into multiple longitudinal reinforcement arrangement zones, and longitudinal reinforcement 4 is arranged in each longitudinal reinforcement arrangement zone.

[0024] S4: Calculate the length of longitudinal reinforcement bars for each section based on the tower column tilt angle and inner wall profile changes, and generate reinforcement detail drawings and quantity tables.

[0025] In this embodiment, by reading the three-dimensional model of the bridge tower structure and dividing the tower column into different sections from bottom to top based on the thickening and recessing position of the inner wall of the tower column, a corresponding control section 1 and longitudinal reinforcement control boundary 2 are generated for each section. Based on the control section 1 and longitudinal reinforcement control boundary 2 of each section, the longitudinal reinforcement arrangement area 3 of the control section 1 of each section is divided into multiple longitudinal reinforcement arrangement partitions, and longitudinal reinforcement 4 is arranged in each longitudinal reinforcement arrangement partition, so that the longitudinal reinforcement positions of the longitudinal reinforcement arrangement partitions of each section are corresponding, improving the aesthetics of the design drawings, simplifying the construction control process, and improving the verification efficiency. The program automatically calculates the longitudinal reinforcement length corresponding to each section and generates reinforcement detail drawings and quantity tables, improving the accuracy and efficiency of bridge tower reinforcement design, providing a reliable basis for refined management and cost control in the construction stage, and reducing on-site material waste.

[0026] The bridge tower structure includes interconnected lower tower column 7, middle tower column 8, and upper tower column 9, such as... Figure 2As shown, a lower crossbeam 10 connects the two lower tower columns 7, and an upper crossbeam 11 connects the two middle tower columns 8. Based on the thickening of the inner wall and the recessed position of the tower columns, the tower columns are divided from bottom to top into the tower bottom section, lower tower column section, lower crossbeam section, middle tower column section, upper crossbeam section, upper tower column section, and tower top section. During construction, starting from the control section 1 at the bottom of the tower column, according to the concrete protective layer thickness, rebar diameter, and design spacing parameters, the corresponding longitudinal rebars 4 of each section are arranged from bottom to top. Adjacent sections are arranged upwards from the bottom section as a base, such as... Figure 3 As shown, each section has a formwork 6 outside the control section 1. Before pouring concrete in the longitudinal reinforcement arrangement area 3, the formwork 6 is used to support the longitudinal reinforcement 4. The formwork 6 is moved to the section where the longitudinal reinforcement 4 needs to be erected using climbing formwork.

[0027] This embodiment reads the three-dimensional model of the bridge tower structure and divides the tower column into different sections from bottom to top based on the thickening and recessing position of the inner wall. It generates corresponding control sections 1 and longitudinal reinforcement control boundaries 2 for each section. Based on the control sections 1 and longitudinal reinforcement control boundaries 2 of each section, the longitudinal reinforcement arrangement area 3 of each section's control section 1 is divided into multiple longitudinal reinforcement arrangement zones. Longitudinal reinforcement 4 is arranged in each longitudinal reinforcement arrangement zone. The length of the longitudinal reinforcement corresponding to each section is calculated based on the tower column's tilt angle and inner wall contour changes, and a detailed drawing and quantity table of the reinforcement are generated. This ensures that the longitudinal reinforcement positions in the corresponding longitudinal reinforcement arrangement zones of each section are consistent, improving the accuracy of the tower column design, reducing material waste, and solving the technical problem in related technologies where the longitudinal reinforcement in the tower column mainly relies on manual experience for construction. Typically, the same shape and quantity of reinforcement are continuously arranged based on the maximum cross-sectional size, which, while ensuring structural safety, easily leads to redundant reinforcement usage and increased material costs.

[0028] Further, see Figure 2-4 As shown, in some embodiments, generating the corresponding control section 1 and longitudinal reinforcement control boundary 2 for each segment includes: S201: Generate the corresponding control section 1 for each segment, wherein the control section 1 of each segment has a first inner wall profile 101 and a second inner wall profile 102 located outside the first inner wall profile 101.

[0029] S202: Connect the corresponding angle positions of the first inner wall contour 101 and the second inner wall contour 102 of each section to form the longitudinal reinforcement control boundary 2.

[0030] In this embodiment, the first inner wall contour 101 and the second inner wall contour 102 have the same shape. The control section 1 is located inside the template 6. The outer wall 61 and the inner wall 62 of the template 6 have the same shape. The second inner wall contour 102 coincides with the inner wall 62 of the template 6. The longitudinal reinforcement control boundary 2 is located at the corner of the control section 1, which is the stress concentration area.

[0031] Further, see Figure 3-5 As shown, in some embodiments, the first inner wall contour 101 and the second inner wall contour 102 form the longitudinal reinforcement arrangement area 3; two adjacent longitudinal reinforcement control boundaries 2 together with the corresponding first inner wall contour 101 and second inner wall contour 102 form a longitudinal reinforcement arrangement partition.

[0032] In this embodiment, the longitudinal reinforcement arrangement area 3 has an irregular shape and is provided with bends. The longitudinal reinforcement arrangement areas are separated by bends. Multiple longitudinal reinforcement arrangement areas are connected to each other, and the dimensions of each longitudinal reinforcement arrangement area are different. Some longitudinal reinforcement arrangement areas are larger in size, while some longitudinal reinforcement arrangement areas are smaller in size.

[0033] Further, see Figure 4 and Figure 5 As shown, in some embodiments, arranging longitudinal reinforcement 4 in each longitudinal reinforcement arrangement zone includes: S301: Determine the centerline 5 of the control boundary for each longitudinal reinforcement layout zone.

[0034] S302: Within each longitudinal reinforcement layout zone, longitudinal reinforcement 4 is arranged symmetrically with the control boundary centerline 5 as the axis of symmetry.

[0035] In this embodiment, the control boundary centerline 5 is the midline of the corresponding longitudinal reinforcement arrangement zone. The longitudinal reinforcement 4 in each longitudinal reinforcement arrangement zone is divided into two groups. The two groups of longitudinal reinforcement 4 are located on both sides of the control boundary centerline 5 and are symmetrically arranged along the control boundary centerline 5 to ensure that the longitudinal reinforcement 4 covers the first inner wall contour 101 of the corresponding longitudinal reinforcement arrangement zone.

[0036] Further, see Figure 5 As shown, in some embodiments, the symmetrical arrangement of longitudinal reinforcement 4 within each longitudinal reinforcement arrangement zone with the control boundary centerline 5 as the axis of symmetry includes: S303: Longitudinal continuous reinforcement 41 and longitudinal discontinuous reinforcement 42 are arranged in the longitudinal reinforcement arrangement zone. Both longitudinal continuous reinforcement 41 and longitudinal discontinuous reinforcement 42 are arranged symmetrically about the center line 5 of the control boundary of the longitudinal reinforcement arrangement zone, and the longitudinal discontinuous reinforcement 42 is distributed among the longitudinal continuous reinforcement 41.

[0037] In this embodiment, for longitudinal reinforcement arrangement zones with larger dimensions in the same section, the longitudinal continuous reinforcement 41 and the longitudinal discontinuous reinforcement 42 are arranged at a specified interval on the inner side of the second inner wall contour 102. The longitudinal continuous reinforcement 41 and the longitudinal discontinuous reinforcement 42 are symmetrically arranged about the control boundary centerline 5 of the longitudinal reinforcement arrangement zone, and the longitudinal discontinuous reinforcement 42 is distributed between the longitudinal continuous reinforcement 41, ensuring that the longitudinal reinforcement 4 covers the second inner wall contour 102 of the corresponding longitudinal reinforcement arrangement zone. Before calculating the longitudinal reinforcement length corresponding to each section and generating the reinforcement detail drawing and quantity table, the longitudinal reinforcement 4 is systematically numbered and labeled according to the longitudinal reinforcement position of each section and the attributes of the longitudinal continuous reinforcement 41 or the longitudinal discontinuous reinforcement 42.

[0038] Further, see Figure 5 As shown, in some embodiments, the symmetrical arrangement of longitudinal reinforcement 4 within each longitudinal reinforcement arrangement zone with the control boundary centerline 5 as the axis of symmetry includes: S304: Longitudinal continuous reinforcement 41 is arranged in all longitudinal reinforcement layout zones, and the longitudinal continuous reinforcement 41 is arranged symmetrically about the control boundary centerline 5 of the longitudinal reinforcement layout zone.

[0039] S305: Within a partial longitudinal reinforcement layout zone, all longitudinal discontinuous reinforcement 42 is arranged, and the longitudinal discontinuous reinforcement 42 is arranged symmetrically about the control boundary centerline 5 of the longitudinal reinforcement layout zone. The size of the longitudinal reinforcement arrangement zone with longitudinal continuous reinforcement 41 and longitudinal discontinuous reinforcement 42 is larger than the size of the longitudinal reinforcement arrangement zone with all longitudinal continuous reinforcement 41, and the size of the longitudinal reinforcement arrangement zone with longitudinal continuous reinforcement 41 and longitudinal discontinuous reinforcement 42 is larger than the size of the longitudinal reinforcement arrangement zone with all longitudinal discontinuous reinforcement 42.

[0040] In this embodiment, for longitudinal reinforcement arrangement zones with smaller dimensions in the same section, all longitudinal continuous reinforcement 41 or longitudinal discontinuous reinforcement 42 are arranged at specified intervals, and the longitudinal continuous reinforcement 41 or longitudinal discontinuous reinforcement 42 is parallel to the control boundary centerline 5 of the longitudinal reinforcement arrangement zone in which it is located.

[0041] Further, see Figure 4 and Figure 5 As shown, in some embodiments, the longitudinal continuous reinforcing bar 41 is parallel to the longitudinal reinforcing bar control boundary 2 on its adjacent side, and the longitudinal discontinuous reinforcing bar 42 is parallel to the centerline 5 of the control boundary of the longitudinal reinforcing bar arrangement zone in which it is located.

[0042] In this embodiment, the longitudinal reinforcement control boundary 2 is located at the bend of the control section 1, which is also the stress concentration area. The longitudinal continuous reinforcement 41 is parallel to the longitudinal reinforcement control boundary 2 on its adjacent side, which helps to improve the local stress state of the tower column and enhance the overall safety of the structure.

[0043] Further, see Figure 5 As shown, in some embodiments, the longitudinal discontinuous reinforcing bar 42 is broken at the position where it intersects with the longitudinal continuous reinforcing bar 41.

[0044] In this embodiment, the longitudinal discontinuous reinforcing bars 42 in the longitudinal reinforcing bar arrangement section with larger dimensions in the same section are interrupted at the position where they intersect with the longitudinal continuous reinforcing bars 41. At the same time, the longitudinal discontinuous reinforcing bars 42 in the longitudinal reinforcing bar arrangement section with smaller dimensions in the same section are interrupted at the position where they intersect with the adjacent longitudinal continuous reinforcing bars 41, so as to avoid physical superposition and interference of the longitudinal reinforcing bars 4 at the spatial intersection point.

[0045] Further, see Figure 6-9 As shown, in some embodiments, arranging longitudinal reinforcement 4 in each longitudinal reinforcement arrangement zone includes: The longitudinal reinforcement 4 located in the section connecting the tower column and the crossbeam is set as a broken line, and the longitudinal reinforcement 4 in the remaining sections is set as a straight line.

[0046] In this embodiment, as Figure 2 As shown, the area connecting the tower column and the crossbeam is treated as a single section. The remaining sections are divided according to the specific variation characteristics of the inner wall profile of the control section 1. The longitudinal continuous reinforcement 41 and the longitudinal discontinuous reinforcement 42 located in the area connecting the tower column and the crossbeam are both in the form of broken lines, such as the lower crossbeam section and the upper crossbeam section, so as to meet the stress requirements of this area while effectively avoiding the cutting off of reinforcement due to the opening of the solid area, thus reducing the difficulty of reinforcement.
