Description

Technical Field

[0001] The invention relates to the technical field of contact network hard crossbeam processing data configuration, and in particular to a contact network hard crossbeam pre-configuration data acquisition method based on Revit. Background Art

[0002] In the renovation construction of the contact site, the hard beam processing data needs to be measured on-site data after the foundation is poured, and then reported to the manufacturer for processing data conversion and production. The manufacturer has a long cycle from purchasing steel → processing → galvanizing → transportation to the site. In the steel processing link, the size of the steel structure needs to be determined according to the construction conditions of the on-site foundation structure, which usually requires measurement and calculation, which seriously affects the construction period. At the current stage of construction, a large margin is usually reserved when making materials such as hanging columns and support columns, and secondary cutting is performed during on-site installation. On the one hand, it increases the labor cost of on-site construction and causes a certain amount of material waste. On the other hand, it increases the construction period and the overall construction cost. Summary of the invention

[0003] The purpose of the present invention is to provide a method for obtaining pre-configuration data of contact network hard beams based on Revit. The method can automatically generate the processing dimensions of the contact network hard beams by software according to the relevant parameters and fixed parameters of the completed infrastructure, thereby improving the efficiency of obtaining processing data and obtaining data with high accuracy, avoiding the phenomenon of secondary processing on site, greatly shortening the construction period, reducing construction costs, and having strong scalability.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A method for obtaining pre-configuration data of a contact network hard beam based on Revit, wherein the contact network hard beam comprises support columns arranged at intervals, side beams fixedly arranged on one side of the top of the support columns, and a middle beam fixedly arranged between two side beams, a suspender column is fixedly installed at the bottom of the side beam and the middle beam, and a contact network component is installed on the suspender column and the support column; the suspender column is located between two adjacent tracks, and the support column is fixedly installed on the top of a foundation structure, and the method comprises the following steps:

[0006] Step 1: Fixed parameter setting: According to the design specification of the contact network hard beam, determine the height h0 between the rail surface and the ground, the height h2 between the rail surface and the contact wire, the height h3 between the contact wire and the top of the contact network component, and the insulation height h4 between the top of the contact network component and the bottom of the middle beam;

[0007] Step 2: variable parameter acquisition: after the foundation structure is completed, measure the height h1 between the foundation structure and the ground, and measure the span L between two adjacent foundation structures;

[0008] Step 3: draw the structural model, create a two-dimensional parameter model of the contact network hard beam in Revit software, create a three-dimensional structural model of the contact network hard beam in Revit software according to fixed parameters and variable parameters, couple the two-dimensional parameter model and the three-dimensional structural model, and input different variable parameters to obtain three-dimensional structural models of different sizes;

[0009] Step 4: Output the hard beam data. Use the built-in program of Revit software to calculate and output the hard beam processing data. The height of the support column H = h2 + h3 + h4 + h5, where h5 is the height of the middle beam; the length of the middle beam L2 and the length of the side beam L1 are calculated by the formula L = L2 + 2L1 + 0.3; the horizontal length of the curved section of the middle beam C = L2-0.9; the arch value of the curved section of the middle beam The length of the davit L0 = h4 + h6, where h6 is the height of the contact network assembly;

[0010] Step five, data collation, the data output in step four is collated and sent to the processing manufacturer for processing and production.

[0011] Preferably, the height h1 between the base structure and the ground ranges from 0.1 m to 0.4 m.

[0012] Preferably, when the value of the height h1 between the base structure and the ground exceeds the value range, the adjustment is performed by adjusting the height and depth of the support columns.

[0013] Preferably, when the span L between two adjacent foundation structures is within different value ranges, the length L2 of the center beam and the length L1 of the side beam are allocated according to design requirements.

[0014] Preferably, the span L between two adjacent foundation structures ranges from 15m to 40m.

[0015] Preferably, the side beam slopes toward the middle at 1:60.

[0016] Preferably, in step 4, the arch radius of the curved section of the center beam is 200m.

[0017] In the present invention, this method is adopted. After the construction plan is approved, a dynamic model is designed in advance in the Revit software according to the design specifications in the design standards, and fixed parameters are input in advance in the dynamic model. After the construction of the basic structure is completed, the variable parameters are measured on site, and the variable parameters are input into the Revit software. The software is used to directly output the structural dimensions to be processed, which reduces the errors and mistakes that may exist in manual calculations, thereby avoiding the traditional manual drawing and on-site adjustment that may affect the accuracy due to operational errors or human factors.

[0018] The processing data directly obtained by the software is highly accurate, and real-time data processing and analysis can detect potential problems earlier. In addition, when the on-site situation changes or the data is incomplete, only the corresponding parameters need to be updated, which is more efficient than traditional methods.

[0022] The present invention will be further described below in conjunction with the accompanying drawings:

[0023] like Figure 1 and Figure 2 A method for obtaining data for pre-configuration of contact network hard beams based on Revit is shown, wherein the contact network hard beams include support columns 1 arranged at intervals, side beams 2 fixed to one side of the top of the support columns 1 by flanges and bolts, and a middle beam 3 fixed between the two side beams 2 by flanges and bolts. In the present embodiment, two support columns 1 are provided, and the support columns 1 are made of equal-diameter round steel pipes. A hanging column 4 is fixedly installed at the bottom of the side beams 2 and the middle beam 3 by flanges and bolts, and a contact network assembly 5 is fixedly installed on the hanging column 4 and the support column 1; the hanging column 4 is located directly above the middle of two adjacent tracks 6, and the support column 1 is fixedly installed on the top of the foundation structure 7 by flanges and bolts. The side beams 2 are sloped toward the middle at 1:60. The data acquisition method comprises the following steps:

[0024] Step 1, fixed parameter setting, according to the contact network hard beam design specifications, determine the height h0 between the rail surface and the ground. The positive and negative values ​​of the height difference between the rail surface and the ground are relative to the rail surface elevation 0.00m. It is positive when it is above the rail surface and negative when it is below the rail surface. The height h2 between the rail surface and the contact wire, the value range of h2 is 5.3m to 6.45m, the height h3 between the contact wire and the top of the contact network component 5, and the insulation height h4 between the top of the contact network component 5 and the bottom of the middle beam 3. The fixed parameters include the height h0 between the rail surface and the ground, the height h2 between the rail surface and the contact wire, the height h3 between the contact wire and the top of the contact network component 5, and the insulation height h4 between the top of the contact network component 5 and the bottom of the middle beam 3.

[0025] Step 2, variable parameter acquisition, after the construction of the foundation structure 7 is completed, measure the height h1 between the foundation structure 7 and the ground, and measure the span L between two adjacent foundation structures 7; during construction, the height difference between the top surface of the foundation structure 7 and the rail surface should be ensured to be in the range of 0 to -0.84m, 0 to -0.6m outside the platform range, and 1.2m for the cargo platform. When the actual height difference between the rail and the ground on site is inconsistent with the above, in order to ensure the installation height of the crossbeam, the height h1 of the foundation structure 7 exposed to the ground can be adjusted first. The value range of the height h1 of the foundation structure 7 exposed to the ground is 0.1m to 0.4m. When the value of the height h1 between the foundation structure 7 and the ground exceeds the value range, it is adjusted by adjusting the height and depth of the support column 1. The span L between two adjacent foundation structures 7 has a value range of 15m to 40m. The variable parameters include the height h1 between the foundation structure 7 and the ground and the span L between two adjacent foundation structures 7.

[0026] When the span L between two adjacent foundation structures 7 is within different value ranges, the length L2 of the middle beam 3 and the length L1 of the side beam 2 are allocated according to the design requirements.

[0029] Note: The length of side beam 2 is the nominal length, such as 6.8 (6.5 + 0.3), 6.8m is the nominal length, 6.5 is the actual length, and 0.3m is the distance between the flange of side beam 2 and the center line of the adjacent support column 1.

[0030] Step three, draw the structural model, create a two-dimensional parametric model of the contact network hard beam in Revit software, create a three-dimensional structural model of the contact network hard beam in Revit software according to fixed parameters and variable parameters, couple the two-dimensional parametric model and the three-dimensional structural model, input different variable parameters to obtain three-dimensional structural models of different sizes; of course, the three-dimensional model set up in this step can be used in the early stage of on-site investigation. After the construction plan is approved, the dynamic placement model of the hard beam can be drawn in Revit in advance, and corresponding modifications can be made according to the fixed parameters and variable parameters to produce the model and obtain processing data.

[0031] Step 4: Output the hard beam data. Use the built-in program of Revit software to calculate and output the hard beam processing data. The height of the support column 1 is H = h2 + h3 + h4 + h5, where h5 is the height of the middle beam 3; the length L2 of the middle beam 3 and the length L1 of the side beam 2 are calculated by the formula L = L2 + 2L1 + 0.3; the horizontal length of the curved section of the middle beam 3 is C = L2-0.9; the arch value of the curved section of the middle beam 3 is The length L0 of the suspension column 4 is h4+h6, wherein h6 is the height of the contact network assembly 5; the arch radius of the curved section of the middle beam 3 is 200m.

[0032] Step five, data collation, the data output in step four is collated and sent to the processing manufacturer for processing and production.

Under the concept of the present invention, technical solutions that have not been substantially changed are still within the scope of protection.
