Background Art

[0002] Buildings such as super-high concrete bridge towers and super-high pier columns have the characteristics of high height and similar cross-sections. The number of steel bars in the building is huge and the length dimensions are different. During the construction of steel bar binding in buildings, mainly through manual estimation of cutting and manual binding operations, the process is complicated and the task is heavy. With the in-depth popularization of mechanization in the field of building construction, the use of the steel bar component construction technology based on the steel bar bending mesh sheet can effectively reduce the labor intensity, improve the quality of steel bar construction, and save the construction period, and is widely promoted.

[0003] When using mechanized production of steel bar bending mesh sheets, it is necessary to more accurately determine the technical parameter information of the mesh sheet such as the length of the steel bar, the position of the bending point, and the bending angle. And through manual calculation, there are the characteristics of low efficiency, easy to make mistakes, and difficult to detect. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for drawing the developed drawing of the bridge tower steel bar mesh sheet, which can quickly and accurately draw the developed drawing of the mesh sheet, generate the steel bar cutting list, and obtain the geometric feature technical elements of the steel bar mesh sheet for guiding the mechanized production of the mesh sheet.

[0005] In order to achieve these and other advantages according to the present invention, a method for drawing the developed drawing of the bridge tower steel bar mesh sheet is provided, including the following steps:

[0006] Step 1, through three-dimensional modeling, construct a three-dimensional model of the bridge tower;

[0007] Step 2, strip from the three-dimensional model the spatial model formed by the outlines where the center lines of each layer of stirrups are located;

[0008] Step 3, expand the spatial model formed by the outlines where the center lines of the stirrups are located into a plane to form a contour plane CAD graph; adjust the actual contour size of the stirrup filling in the contour plane CAD graph;

[0009] Step 4, fill the steel bars in the expanded plane to form a developed drawing of the steel bar mesh sheet, extract the steel bar data from the developed drawing of the steel bar mesh sheet to form a steel bar cutting list, and output the developed drawing of the steel bar mesh sheet and the steel bar cutting list to the display platform.

[0010] Preferably, the specific content of step 1 is to perform three-dimensional modeling according to the dimensions marked on the bridge tower model and the reinforcement drawing;

[0011] Preferably, step 2 is specifically as follows: According to the deviation position of the center line contour of the stirrups relative to the outer contour of the building in the design drawing, a three-dimensional model formed by the center line of the stirrups is constructed, and modeling is carried out separately according to the positions of different circular stirrups on the cross-section.

[0012] Preferably, step 3 is specifically as follows: According to the spatial model formed by the center line of the stirrups, along the direction of the main reinforcement, the spatial model formed by the center line of the stirrups is unfolded to generate a CAD drawing of the contour plane where the center line of the stirrups is located;

[0013] The unfolding adjustment is specifically as follows: After the stirrup contour plane is unfolded into a CAD drawing, according to the bending adjustment value of the stirrups and the compensation value of the bending fold line on the mesh production equipment, the position of the bending fold line is adjusted in the overall mesh unfolding drawing to determine the actual contour dimensions of the stirrup filling in the mesh unfolding drawing.

[0014] Preferably, filling the steel bars in step 4 is specifically as follows: According to the positions and spacings of the steel bars in the steel bar reinforcement rules, the main reinforcement and stirrups are filled to generate a CAD drawing of the unfolded steel bar mesh;

[0015] Cut and mark the unfolded drawing of the steel bar mesh: According to the segment division of the tower column construction, the unfolded drawings of each steel bar mesh are divided into different segments; the positions of the bending fold lines, the positions of the main main reinforcements, the bending angles of the steel bars, the positions of the loose-bound steel bars, the spacing of the main reinforcements, and the spacing of the stirrups are marked in each segment.

[0016] The present invention has at least the following beneficial effects: When the steel bar mesh is produced by mechanical industrialization, the production parameters of different meshes are different, and it is necessary to conveniently obtain the production technical elements of each mesh. During the mesh production process, it is also necessary to compare the mesh production parameters with the deviations in the actual manufacturing process at any time, and at the same time, according to the mesh technical parameters, quickly and accurately realize the steel bar cutting. The method of the present application quickly translates from the steel bar reinforcement design drawing into a mesh mechanical processing technical drawing that can be used to guide the mesh mechanized production, and is used for setting the on-site equipment parameters and quickly detecting the mesh.

Therefore, all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, and the specific implementation process is as follows:

[0028] As Figure 1 shown, the present invention provides a method for drawing the developed view of the bridge tower steel bar mesh, including the following steps:

[0029] Step 1, through three-dimensional modeling, construct a three-dimensional model of a bridge tower with a complex configuration;

[0030] Step 2, strip out the spatial model formed by the contours where the centerlines of each layer of stirrups are located from the three-dimensional model;

[0031] Step 3, expand the spatial model formed by the contours where the centerlines of the stirrups are located into a plane to form a contour plane CAD drawing; adjust the actual contour dimensions of the stirrup filling in the contour plane CAD drawing;

[0032] Step 4, fill the steel bars in the expanded plane to form a developed view of the steel bar mesh, extract the steel bar data (parameters of stirrups and main reinforcements) from the developed view of the steel bar mesh to form a steel bar cutting list, and output the developed view of the steel bar mesh and the steel bar cutting list to the display platform.

[0033] This technical solution may also include the following technical details to better achieve the technical effect: Step 1 specifically involves three-dimensional modeling according to the dimensions marked on the bridge tower model and reinforcement drawings; Figure 2 As shown, construct a three-dimensional model of the building. When constructing the three-dimensional model, it is necessary to keep it consistent with the design drawings.

[0034] The technical solution may also include the following technical details to better achieve the technical effect: The step 2 is specifically as follows: according to the deviation position of the center line contour of the stirrups relative to the outer contour of the building in the design drawing, a three-dimensional model formed by the center line of the stirrups is constructed. Different ring stirrups are located in different contour sections. According to the different positions of the ring stirrups on the section, models are respectively constructed, such as Figure 3 .

[0035] The technical solution may also include the following technical details to better achieve the technical effect: Step 3 is specifically: according to the spatial model formed by the center line of the stirrups, the spatial model formed by the center line of the stirrups is unfolded along the direction of the main reinforcement to generate a contour plane CAD figure where the center line of the stirrups is located, such as Figure 4 ;

[0036] The specific expansion adjustment is as follows: after the stirrup outline plane is expanded into a CAD drawing, the position of the bending line is adjusted in the overall mesh expansion drawing according to the stirrup bending adjustment value and the compensation value of the bending line on the mesh production equipment to determine the actual outline size of the stirrup filling in the mesh expansion drawing.

[0037] This technical solution may also include the following technical details to better achieve the technical effect: In step 4, filling the steel bars is specifically as follows: filling the main bars and stirrups according to the steel bar position and spacing in the steel bar reinforcement rules, and generating a steel mesh expansion diagram; the steel bar parts are made by splicing meshes, so it is necessary to divide the part section into two bent meshes in advance, and then splice them into a ring after the mesh is made. The division rules are adjusted and determined according to actual conditions. According to the part section division rules, the overall mesh expansion diagram is cut into two parts according to the cross-section cutting rules.

[0038] Cut out the mesh expansion diagram and mark it: Figure 5 According to the segment division of tower column construction, the first segment and the second segment, the expansion diagram of each steel mesh is divided into different segments; the bending line position, main main reinforcement position, reinforcement bending angle, loose reinforcement position, main reinforcement spacing, stirrup spacing are marked in each segment, such as Figure 6 .

[0039] In the above technical solution, the modeling method of the present application can guide the production of mesh sheets. According to the developed drawing of the steel bar mesh sheet, relevant production parameters on the steel bar mesh sheet production line can be adjusted. At the same time, in the CAD software of the developed drawing of the steel bar mesh sheet, by using the data extraction function in the tool, the length data of the stirrups for the entire segment can be exported as an excel spreadsheet, and the table can be simply sorted. After setting the elevation and marking the names of each surface, it is sorted into the format required by the mesh sheet manufacturing equipment software and transmitted to the mesh sheet manufacturing equipment for mechanical production of the mesh sheet. At the same time, during the production process of the mesh sheet and after the mesh sheet is formed, the key dimensions of the relevant mesh sheets are inspected and reviewed with reference to the developed drawing of the mesh sheet. Taking the export of stirrup data as an example, in CAD, click on Tools, Data Extraction, Create a data export format template, select the stirrups for which data needs to be exported, select the form of stirrup export data, select the storage location, and click OK to export the stirrup length data to the electronic excel table. Then, in the excel table, data such as elevation and the names of each surface are supplemented to form the stirrup cutting list for this segment. The data in the table is transplanted into the general table for mesh sheet cutting and production of the flexible manufacturing production line of the steel bar mesh sheet, the corresponding mesh sheet production parameters are set, and imported into the equipment, thus completing the equipment parameter setting.
