It achieves parameterization and standardization of detailed rebar arrangement, enabling users to quickly define node information through a unified parameter input interface. Based on rules, it automatically draws the positions of components such as rebars, sleeves, and connecting plates, improving drawing and modeling efficiency and avoiding repetitive manual work. While adhering to the rules, it incorporates manually adjustable parameter input, simultaneously satisfying the rationality and personalization of the arrangement.

[0062] This rebar arrangement method, through a preset parametric logic and rule system, can automatically arrange the rebar and automatically draw the cross-sectional diagram within seconds after the user inputs the parameters, improving efficiency by more than 80%. It solves the problems of low modeling efficiency and easy errors caused by the traditional method, where designers manually draw cross-sectional diagrams and rely on experience to locate, modify, and adjust them.

The system determines the distribution direction of the flange and web through parameters, calculates whether the rebar can pass through the beam by combining the clear distance between the steel section and the beam, and automatically modifies the cross-sectional diagram according to different arrangement methods (sleeve or connecting plate), improving the feasibility and adaptability of the arrangement scheme.

[0065] The plug-in interface of this rebar layout system adopts a partitioned parameter input design, which is clearly categorized and logically intuitive, allowing users to complete CAD drawings without mastering complex operating procedures.

[0066] This rebar layout system generates high-precision rebar layout diagrams through automation and parameterization, improving design efficiency, reducing design rework, and standardizing node construction and rebar layout. This method can effectively shorten the design cycle in the pre-construction detailing stage and indirectly save design costs. Attached Figure Description

[0074] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following detailed description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0075] like Figure 1As shown, this embodiment provides a method for arranging reinforcing bars, including the following steps S1-S3.

[0076] S1: Obtain component node parameters, including beam 1 parameters, column parameters, column steel section 2 parameters, rebar 3 parameters, layout information parameters, and protective layer thickness parameters.

[0077] The parameters for beam 1 can include beam 1 width, beam 1 height, and beam 1 offset. Beam 1 offset is short for beam 1 offset relative to the column center.

[0078] Column parameters can include column length and column width.

[0079] The parameters of the column steel section 2 can include the type of steel section 2, the parameters of steel section 2, and the offset parameters of steel section 2.

[0080] The type of steel section 2 may include box section steel section 2, I-beam steel section 2, H-beam steel section 2, or cross section steel section 2. If the type of steel section 2 is box section steel section 2, the parameters of the steel section 2 include the length and width of the steel section 2; if the type of steel section 2 is I-beam steel section 2 or H-beam steel section 2.

[0081] The parameters of the steel section include flange length, flange thickness, web length, and web thickness.

[0082] The offset parameters for section 2 include section 2 offset and section 2 offset. Section 2 offset and section 2 offset are abbreviations for the offset of section 2 relative to the column center.

[0083] The three parameters of the reinforcing bars can include top reinforcement parameters, web reinforcement parameters, bottom reinforcement parameters, and stirrup parameters. Top reinforcement parameters include the number and size of top reinforcement bars; web reinforcement parameters include the number and size of web reinforcement bars; bottom reinforcement parameters include the number and size of bottom reinforcement bars; and stirrup parameters include the size of stirrups.

[0084] The layout information parameters may include the minimum net spacing of the three rows of reinforcing bars, the location of beam 1, and the layout method of the three rows of reinforcing bars.

[0085] The minimum net spacing of three rows of reinforcing bars includes the horizontal net spacing s. 水平 The horizontal and vertical clearance are abbreviations for the minimum horizontal and vertical clearance values, respectively.

[0086] The position of beam 1 is its orientation relative to the column (up, down, left, right).

[0087] The three-row arrangement of reinforcing bars includes: 1. Integral sleeve (such as...) Figures 3-5 1. As shown), all reinforcing bars 3 are connected using sleeves; 2. Integral connecting plate, all reinforcing bars 3 are connected using connecting plates (for inclined beam 1); 3. First row connecting plate (as shown) Figure 6As shown), the first layer of reinforcing bars 3 (i.e., the row of reinforcing bars 3 above the top reinforcement or the row of reinforcing bars 3 below the bottom reinforcement) are connected using connecting plates, and the rest are connected using sleeves;

[0088] The protective layer thickness parameter can include horizontal protective thickness and vertical protective thickness.

[0089] The column length and column width mentioned above represent the column length in the X direction and the column width in the Y direction, respectively. The steel section length 2 and steel section width 2 represent the steel section length 2 in the X direction and the steel section width 2 in the Y direction, respectively. They are not related to the actual meaning of the longer side being the length and the shorter side being the width.

[0090] Specifically, the user selects the required steel profile type 2 on the software page, and the page automatically matches different parameters to fill in the information. Then, the beam 1 parameters, column parameters, reinforcement 3 parameters, arrangement information parameters, and protective layer thickness parameters are input into the node parameter input module. Then, the rule parsing and processing module parses and processes the input node parameters. This step S1 realizes the acquisition of component node parameters.

[0091] S2: The input node parameters are parsed and processed according to the preset rebar 3 arrangement algorithm to calculate the rebar 3 data.

[0092] Step S2 may include S21-S24. (Taking box-shaped steel section 2 as an example, assume beam 1 is located below the column.)

[0093] S21: Determine whether there is a gap between beam 1 and steel section 2 based on the parameters of beam 1 and column 2.

[0094] If a gap exists, calculate the width of the gap between beam 1 and steel section 2.

[0095] If there is no gap on both sides, the connection method is determined according to the set priority or manual selection, and the data of rebar 3 is calculated.

[0096] S22: Based on the gap situation in step S21, the net spacing of the reinforcing bars 3 located in the gap and the maximum number of reinforcing bars 3 in a row are calculated using the reinforcing bar 3 arrangement algorithm.

[0097] Step S22 may include:

[0098] S221: If there is no gap on both sides, proceed to step S23;

[0099] S222: As Figure 3 and Figure 4 As shown, if there are gaps, the net spacing s of the reinforcing bars 3 间隙 The calculation formula is:

[0100] .

[0101] In the formula:

[0102] d 钢筋 : Diameter of gluten / bottom gluten (unit: mm)

[0103] s 间隙 The net spacing of the reinforcing bars 3 in the gap (unit: mm) refers to the distance between two adjacent reinforcing bars 3.

[0104] c: Protective layer thickness (unit: mm)

[0105] d 箍筋 : Stirrup diameter (unit: mm)

[0106] l: Gap width

[0107] j: j≥2, traversing from 2 to obtain s 间隙 When s 间隙 Greater than the horizontal net spacing s 水平 When j is taken as its maximum value, the maximum number of 3 steel bars j that can be arranged in a row in the gap is obtained. max .

[0108] When there are gaps on both sides between beam 1 and steel section 2, calculate the width of the left gap (left gap) and the right gap (right gap) between beam 1 and steel section 2. The actual usable gap width can be calculated as follows: Actual usable gap left = gap left - 2 times the horizontal protective layer thickness - stirrup size. For example, if gap left = 200, horizontal protective layer thickness = 25, stirrup size = 10, and top reinforcement size = 28, then the actual usable gap left = 140. Based on the actual usable gap width, perform a traversal calculation according to the preset calculation formula to determine the number of steel bars 3 that can pass through (e.g., three steel bars 3 can pass through in the example). The above calculation must satisfy that the net spacing s2 of the steel bars 3 is greater than the horizontal net spacing. When using sleeve connection, simply replace the net spacing of the steel bars 3 in the above calculation formula with the net spacing of the sleeve.

[0109] There are two special cases: 1. The gap can only pass through one steel bar 3; 2. The gap cannot pass through steel bar 3.

[0110] 1. When the gap can only pass through one steel bar 3, that is, the gap width l is greater than or equal to the diameter d of steel bar 3. 钢筋 Add twice the protective layer thickness (2c) and stirrup diameter (d). 箍筋 The sum of the values, and the gap width l is less than twice the diameter d of the reinforcing bar. 钢筋 Add twice the protective layer thickness (2c) and stirrup diameter (d). 箍筋 Add 3 clear spacings of reinforcing bars 间隙 The sum. Specifically: l ≥ (d 钢筋 +2c+d 箍筋 ), and l < (2d) 钢筋 +2c+d 箍筋 +s间隙 ).

[0111] 2. When the gap cannot pass through the reinforcing bar 3, that is, when the gap width l is less than the diameter d of the reinforcing bar 3. 钢筋 Add twice the protective layer thickness (2c) and stirrup diameter (d). 箍筋 The sum, specifically: l < (d 钢筋 +2c+d 箍筋 ).

[0112] Step S22 automates the calculation of parameters such as the gap and number of reinforcing bars 3 located between beam 1 and steel section 2, improving calculation efficiency and accuracy.

[0113] S23: Based on the gap situation in step S21, the net spacing of the reinforcing bars 3 located in the steel section 2 and the maximum number of reinforcing bars 3 in a row are calculated using the reinforcing bar 3 arrangement algorithm.

[0114] Step S23 may include:

[0115] S231: As Figure 5 As shown, if there are no gaps on both sides, the formula for calculating the net spacing s of the reinforcing bars is:

[0116]

[0117] In the formula:

[0118] d 钢筋 : Diameter of gluten / bottom gluten (unit: mm)

[0119] s: Clear spacing of rebar 3 (unit: mm), that is, the spacing between two adjacent rebar 3.

[0120] c: Protective layer thickness (unit: mm)

[0121] d 箍筋 : Stirrup diameter (unit: mm)

[0122] b: 2mm length of the steel section.

[0123] i: i≥2, starting from 2, iterate to obtain s, when s is greater than the horizontal net spacing s 水平 When i is taken as its maximum value, the maximum number of 3 reinforcing bars that can be arranged in one row within section 2 of the steel profile is obtained. max .

[0124] S232: As Figure 4 As shown, if there is a gap on one side, the formula for calculating the net spacing s1 of the reinforcing bars 3 is:

[0125] ;

[0126] In the formula:

[0127] d 钢筋 : Diameter of gluten / bottom gluten (unit: mm)

[0128] s1: Clear spacing of reinforcing bars 3 (unit: mm), that is, the spacing between two adjacent reinforcing bars 3.

[0129] c: Protective layer thickness (unit: mm)

[0130] d 箍筋 : Stirrup diameter (unit: mm)

[0131] b: 2mm length of the steel section.

[0132] i: i≥2, starting from 2, iterate to obtain s1. When s1 is greater than the horizontal net spacing s 水平 When i is taken as its maximum value, the maximum number of 3 reinforcing bars that can be arranged in one row within section 2 of the steel profile is obtained. max1 .

[0133] S233: As Figure 3 As shown, when there are gaps on both sides, the formula for calculating the net spacing s2 of the reinforcing bars 3 is:

[0134] ;

[0135] In the formula:

[0136] d 钢筋 : Diameter of gluten / bottom gluten (unit: mm)

[0137] s2: Clear spacing of reinforcing bars 3 (unit: mm), that is, the spacing between two adjacent reinforcing bars 3.

[0138] c: Protective layer thickness (unit: mm)

[0139] d 箍筋 : Stirrup diameter (unit: mm)

[0140] b: 2mm length of the steel section.

[0141] i: i≥2, starting from 2, iterate to obtain s2, when s2 is greater than the horizontal net spacing s 水平 When i is taken as its maximum value, the maximum number of 3 reinforcing bars that can be arranged in one row within section 2 of the steel profile is obtained. max2 .

[0142] The calculation for the actual usable steel section length 2 is as follows:

[0143] When there is a gap on both sides, deduct the sum of twice the horizontal protective thickness and once the diameter of the reinforcing bar from the length of the steel section 2;

[0144] When there is a gap on one side, deduct the sum of twice the horizontal protective thickness, once the diameter of the reinforcing bar, and once the diameter of the stirrup from the length of the steel section 2;

[0145] When there is no gap, deduct the sum of twice the horizontal protective thickness, once the diameter of the reinforcing bar, and twice the diameter of the stirrups from the length of the steel section 2.

[0146] If it is an I-beam or H-beam, then replace the length 2 of the section with the flange length / web length.

[0147] Step S23 can calculate the net spacing of the reinforcing bars 3 and the maximum number of reinforcing bars 3 in a row based on the actual available width of the steel section 2 using the reinforcing bar 3 layout algorithm. This realizes the automated calculation of parameters such as the number of reinforcing bars 3 and the spacing within the steel section 2, improving calculation efficiency and accuracy.

[0148] S24: Based on the net spacing of the reinforcing bars 3 and the maximum number of reinforcing bars 3 in a row calculated in steps S22 and S23, calculate the number of rows of reinforcing bars 3 by the arrangement of reinforcing bars 3.

[0149] The formula for calculating the number of rows of steel bars in S24 is:

[0150]

[0151] In the formula:

[0152] t: Number of layers (1 or more).

[0153] n: Total number of steel bars (3)

[0154] a: The maximum number of 3 steel bars that can be arranged in a single layer, i.e., a = i max +j max i max It can also be i max1 or i max2 .

[0155] like Figure 3 As shown, the arrangement of the reinforcing bars 3 in step S24 is as follows:

[0156] S241: Fill the first few layers, except for the last one;

[0157] S242: When the first row of steel bars 3 is not fully arranged, the second row of steel bars 3 is arranged from the outside to the inside, so that the steel bars 3 pass through the gap between the beam 1 and the steel section 2.

[0158] S243: Arrange the reinforcing bars 3 evenly within the steel section 2.

[0159] Step S24 not only calculates the number of rows of rebar 3, but also, in conjunction with the layout drawing rules, realizes the automated layout of rebar 3. This not only improves the layout efficiency, but also improves the accuracy and standardization of the layout, while enhancing the adaptability of the layout scheme.

[0160] Step S2 above automatically adapts the corresponding layout strategy based on the different types of steel sections 2 in the column (including box-section steel sections 2, I-section steel sections 2, cross-section steel sections 2, etc.) and component node parameters, combined with the actual positions of beam 1 and steel sections 2 (the offset of beam 1 and steel sections 2 relative to the column). It can also automatically modify the cross-sectional diagram according to different reinforcement 3 layout methods, improving the feasibility and adaptability of the layout scheme. By decoupling and encapsulating structural parameters and reinforcement rules into a general algorithm, it can handle various node construction variations, truly realizing "parameter-driven + rule-controlled" automated reinforcement 3 layout, significantly improving design efficiency and adaptability, and is suitable for widespread application in the design and detailed development stages of steel section 2 concrete structures.

[0161] S3: Draw the cross-sectional view in CAD based on the data of the reinforcing bar 3 obtained in step S2.

[0162] Step S3 may include:

[0163] S31: Draw the sections of beam 1 and steel section 2 based on the offset parameters of beam 1 and steel section 2 and the position of beam 1;

[0164] S32: Draw the cross section of the reinforcing bar 3 based on the data of the reinforcing bar 3 calculated in step S2. The data of the reinforcing bar 3 includes the net spacing of the reinforcing bar 3, the number of reinforcing bars 3, and the number of rows of reinforcing bars 3.

[0165] Step S3 can automatically draw the cross sections of beam 1, steel section 2, and reinforcing bar 3 based on the calculation results in step S2, which improves drawing efficiency, ensures drawing accuracy, facilitates construction guidance, and facilitates subsequent modifications and adjustments.

[0166] The above method, through plug-in development in CAD and combined with user input parameters and node construction rules, can automatically complete the task of arranging the reinforcing bars 3 in a beam-column joint structure containing steel section 2. It achieves parameterization and standardization of the detailed arrangement of reinforcing bars 3, enabling users to quickly define node information through a unified parameter input interface. Based on rules, it automatically draws the positions of reinforcing bars 3, sleeves, connecting plates, and other components, improving drawing and modeling efficiency and avoiding repetitive manual work. While adhering to the rules, it incorporates manually adjustable parameter input, simultaneously satisfying the rationality and personalization of the arrangement.

[0167] like Figure 2 As shown, this embodiment also provides a three-row reinforcement system, including a node parameter input module, a rule parsing and processing module, and a CAD image drawing module.

[0168] The node parameter input module is used to obtain component node parameters, including beam 1 parameters, column parameters, column steel section 2 parameters, rebar 3 parameters, arrangement information parameters, and protective layer thickness parameters. The module interface adopts a partitioned parameter input design, with clear categorization and intuitive logic, facilitating parameter input for users.

[0169] The rule parsing and processing module is used to parse and process the input node parameters according to the preset rebar arrangement algorithm, and calculate the rebar data. Specifically, it includes:

[0170] The analysis module is used to determine whether there is a gap between beam 1 and steel section 2 based on the parameters of beam 1 and column;

[0171] If a gap exists, calculate the width of the gap between beam 1 and steel section 2;

[0172] If there are no gaps on both sides, the connection method is determined according to the set priority or manual selection, and the layout information parameters are calculated.

[0173] The first calculation module is used to calculate the net spacing of the reinforcing bars 3 located between beam 1 and steel section 2 and the maximum number of reinforcing bars 3 in a row based on the gap situation in the analysis module and the reinforcing bar 3 arrangement algorithm.

[0174] The second calculation module is used to calculate the net spacing of the reinforcing bars 3 located in the steel section 2 and the maximum number of reinforcing bars 3 in a row based on the gap situation in the analysis module and the reinforcing bar 3 arrangement algorithm.

[0175] The layout module is used to calculate the number of rows of steel bars 3 based on the net spacing of steel bars 3 and the maximum number of steel bars 3 in a row calculated from the first calculation module and the second calculation module.

[0176] This module can automatically determine the actual spatial relationship, different processing methods for different types of steel sections 2, and whether the gap can accommodate reinforcing bars 3, based on user-input parameters, avoiding structural irregularities caused by human error. It can also handle different types of steel sections 2 in columns (including box-shaped steel sections 2, I-beam steel sections 2, cross-shaped steel sections 2, etc.) and automatically adjust the reinforcing bar 3 arrangement strategy according to the steel section 2 structure. If the steel section 2 is an I-beam steel section 2, the system determines the distribution direction of the flange and web through parameters, calculates whether the reinforcing bars 3 can pass through based on the clear distance between the steel section 2 and the beam 1, and automatically modifies the cross-sectional diagram according to different arrangement methods (sleeve or connecting plate connection), improving the feasibility and adaptability of the arrangement scheme.

[0177] The CAD image drawing module is used to draw cross-sectional views in CAD based on the obtained rebar data. This module automatically generates high-precision rebar layout drawings, improving design efficiency, reducing design rework, and standardizing node construction and rebar layout.

[0178] Specifically, in the Rebar 3 input interface (software page) of the node parameter input module, the node parameters are entered. After the input is completed, the rule parsing and processing module parses and processes the input node parameters, calculates the net spacing, number of rows, position, maximum number of rows of rebar 3, and other data. Finally, based on the calculated rebar 3 data, the cross-sectional view is drawn in CAD.

[0179] This three-row steel reinforcement system not only significantly improves modeling efficiency and the accuracy and standardization of node construction, but also adapts to various steel-embedded structures, enhancing versatility.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
