Description

Technical Field

[0001] This invention belongs to the field of automatic reinforcement technology, and particularly relates to an automatic reinforcement arrangement method for longitudinal reinforcement of beams. Background Technology

[0002] In BIM applications, beam reinforcement quantity calculation is a crucial step, and longitudinal reinforcement is a vital component of this calculation. To quickly calculate the longitudinal reinforcement quantity, an automatic reinforcement placement method is needed based on the beam model.

[0003] In the prior art, Chinese patent CN110119552A discloses a BIM method for automatically generating the bottom longitudinal reinforcement and side structural reinforcement of beams. It mainly includes several steps such as establishing a beam structure model through the mainstream BIM software platform Revit during the implementation of BIM technology, intelligently calculating various parameters of the bottom longitudinal reinforcement and side structural reinforcement of beams through visual programming, and finally generating the bottom longitudinal reinforcement and side structural reinforcement of beams that conform to the national building standard design atlas.

[0004] The limitation of existing technology is that the BIM method, which automatically generates the bottom longitudinal reinforcement and side structural reinforcement of the beam, can only complete the reinforcement of continuous bars, and cannot complete the reinforcement of non-continuous bars. In most cases, the bottom longitudinal reinforcement and side structural reinforcement of the beam are continuous bars, while the top longitudinal reinforcement of the beam is likely to be non-continuous bars. That is, the existing technology cannot complete the reinforcement of the top longitudinal reinforcement of the beam, and the reinforcement range is limited.

[0005] Therefore, it is necessary to provide a new method for automatically placing longitudinal reinforcement in beams to solve the above-mentioned technical problems. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] Based on this, the present invention provides an automatic reinforcement arrangement method for beam longitudinal reinforcement, in order to solve the technical problem that existing automatic generation methods for beam longitudinal reinforcement cannot complete the reinforcement arrangement of the upper longitudinal reinforcement of the beam.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this invention proposes an automatic reinforcement placement method for longitudinal reinforcement in beams, comprising the following steps:

[0010] S1: Read the existing rebar data file to obtain beam rebar data; load the existing beam model file to obtain the beam model and beam model parameters;

[0011] S2, obtain the centerline of the top surface of the beam model. The centerline of the top surface of the beam is a line segment located in the middle of the top surface of the beam model and whose length direction is consistent with the length direction of the beam model. The starting point, midpoint, and endpoint of the center of the top surface of the beam are P1, P2, and P3, respectively.

[0012] S3 generates three sections and the corresponding point steel;

[0013] S31, Generate three sections: Generate three sections parallel to the end faces of the beam model along the length direction of the beam model, namely the first section, the second section and the third section. The first section passes through P1, the second section passes through P2 and the third section passes through P3.

[0014] S32, based on three sections, obtain the outer contour line of the beam at the section position;

[0015] The intersection lines of the first section, the second section, and the third section with the outer contour surface of the beam model are respectively the first outer contour line, the second outer contour line, and the third outer contour line. The first contour line encloses the first beam section, the second contour line encloses the second beam section, and the third contour line encloses the third beam section.

[0016] S33, Based on the beam reinforcement data, obtain the intersection points of the beam longitudinal reinforcement with the first beam section, the second beam section and the third beam section respectively, set the intersection points as point steel, and attach the corresponding reinforcement specifications to each point steel;

[0017] S4 generates the longitudinal reinforcement of the beam;

[0018] S41, extract the relative positions of the first beam section, the second beam section, and the third beam section of the point steel respectively;

[0019] S42, Copy the centerline of the top surface of the beam and offset it to the location of the point steel to obtain the original steel reinforcement line;

[0020] S43, obtain the final rebar line;

[0021] Using all the aforementioned point steel bars as the screening objects, the following criteria for judging continuous reinforcing bars are used: Criteria for judging continuous reinforcing bars: In the first beam section, the second beam section, and the third beam section, the relative positions of the point steel bars are the same, and the specifications of the reinforcing bars are the same.

[0022] The longitudinal reinforcement of the beam corresponding to the point steel that meets the judgment condition of the through reinforcement is the through reinforcement, and its original reinforcement line is the final reinforcement line.

[0023] The longitudinal reinforcement of the beam corresponding to the point steel that does not meet the judgment conditions of continuous reinforcement is non-continuous reinforcement. The original reinforcement line corresponding to this type of point steel needs to be cut in accordance with the building code and standard to obtain the final reinforcement line.

[0024] Preferably, the method for obtaining the centerline of the top surface of the beam in step S2 is as follows: if the centerline of the top surface of the beam is already in the reinforcement data file, the centerline of the top surface of the beam is directly obtained through the positional characteristics of the centerline of the top surface of the beam.

[0025] Preferably, if the centerline of the beam top surface is not present in the reinforcement data file, the centerline of the beam top surface must be generated first.

[0026] Preferably, the method for generating the centerline of the beam top surface is as follows: First, obtain all the contour lines of the beam model, then set the beam top surface line filtering conditions according to the characteristics of the beam top surface line, and obtain the top surface line from all the contour lines of the beam model. The beam top surface lines form a rectangle. Then, arbitrarily select one of the long sides of the beam top surface line, and translate it along the direction of the short side of the beam top surface line to the midpoint of the short side of the beam top surface line. The resulting line segment is the centerline of the beam top surface.

[0027] Preferably, the selection criteria for the beam top surface line are: the line located at the very top of all the contour lines, and the height difference between the starting point and the ending point is within a preset range.

[0028] Preferably, when the beam model file is loaded in a three-dimensional Cartesian coordinate interface with X-axis, Y-axis and Z-axis, and the height direction of the beam model is consistent with the Z-axis direction, the height of the points on the line is determined by the Z-axis coordinate when filtering the top surface line of the beam.

[0029] Preferably, the beam model parameters include beam length, beam width, and beam height.

[0030] Preferably, the existing reinforcement data file is located within the flat drawing.

[0031] Preferably, the beam model file is obtained by performing beam analysis on the flat drawing.

[0032] Preferably, the specifications of the reinforcing bars include the diameter, grade, and quantity.

[0033] (III) Beneficial Effects

[0034] Compared with the prior art, the automatic reinforcement arrangement method for longitudinal reinforcement of beams of the present invention has the following advantages:

[0035] This invention provides a method for automatically assigning reinforcement based on beam modeling. It can automatically assign longitudinal reinforcement to beams and provide the steel reinforcement specifications for subsequent calculations, facilitating rapid quantity calculation of beam reinforcement. This method not only enables the configuration of continuous reinforcement but also facilitates the configuration of non-continuous reinforcement. Specifically, this invention allows for the trimming of steel reinforcement through multiple cross-sections, enabling the assignment of non-continuous reinforcement. This technology can also be applied to the configuration of longitudinal reinforcement in variable cross-section beams and folded beams. This method can complete the configuration of bottom longitudinal reinforcement, side structural reinforcement, and top longitudinal reinforcement of beams, expanding the reinforcement range and improving the efficiency and accuracy of automatic generation of beam longitudinal reinforcement.

[0054] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0055] The following is in conjunction with the appendix Figure 1-15 The automatic reinforcement arrangement method for longitudinal reinforcement of beams according to the present invention will be further explained.

[0056] Please refer to this carefully. Figure 15 This invention discloses an automatic reinforcement arrangement method for longitudinal bars in beams, comprising the following steps:

[0057] S1: Read the existing reinforcement data file to obtain the beam reinforcement data. Load the existing beam model file to obtain beam model 1 (e.g., ...). Figure 1 ) and beam model parameters.

[0058] S2, obtain the centerline 2 of the top surface of beam model 1. The centerline 2 is a line segment located at the center of the top surface of beam model 1 and whose length direction is consistent with the length direction of beam model 1. The starting point, midpoint, and endpoint of the centerline 2 are P1, P2, and P3 respectively (e.g., ...). Figure 3 ).

[0059] S3 generates three sections and the corresponding point steel 7.

[0060] S31, Generate three sections: Generate three sections parallel to the end faces of beam model 1 along the length direction of beam model 1, namely the first section, the second section, and the third section (e.g., ...). Figure 4 The first section passes through P1, the second section passes through P2, and the third section passes through P3.

[0061] S32, based on three sections, obtain the outer contour line of the beam at the section position.

[0062] The first, second, and third sections intersect with the outer contour surface of beam model 1, forming the first outer contour line 3, the second outer contour line 4, and the third outer contour line 5, respectively. The first contour line encloses the first beam section, the second contour line encloses the second beam section, and the third contour line encloses the third beam section.

[0063] S33, based on the beam reinforcement data, obtain the intersection points of the beam longitudinal reinforcement with the first beam section, the second beam section, and the third beam section, and designate these intersection points as point reinforcement 7 (e.g., ...). Figure 5 ), and attach the corresponding steel bar specifications to each steel point 7.

[0064] S4 generates the longitudinal reinforcement of the beam.

[0065] S41, extract the relative positions of point steel 7 in the first beam section, the second beam section, and the third beam section respectively.

[0066] S42, copy the centerline 2 of the top surface of the beam and offset it to the position of the point steel 7 to obtain the original steel bar line 6.

[0067] S43, obtain the final rebar line.

[0068] All point steel bars 7 are selected as the screening objects, and the following criteria are used to determine continuous reinforcement. Criteria for determining continuous reinforcement: In the first beam section, the second beam section, and the third beam section, the relative positions of point steel bars 7 are the same, and the steel bar specifications are the same.

[0069] The longitudinal reinforcement of the beam corresponding to the point steel 7 that meets the judgment condition for continuous reinforcement is continuous reinforcement, and its corresponding original reinforcement line 6 is the final reinforcement line.

[0070] The longitudinal reinforcement of the beam corresponding to the point steel 7 that does not meet the criteria for continuous reinforcement is non-continuous reinforcement. The original reinforcement line 6 corresponding to this type of point steel 7 needs to be cut in accordance with the building code and standard to obtain the final reinforcement line.

[0071] As a specific embodiment of the present invention, the method for obtaining the beam top surface centerline 2 in step S2 is as follows: when the beam top surface centerline 2 is already in the reinforcement data file, the beam top surface centerline 2 is directly obtained through the positional characteristics of the beam top surface centerline 2.

[0072] As a specific embodiment of the present invention, when the beam top surface centerline 2 is not present in the reinforcement data file, it is necessary to generate the beam top surface centerline 2 firstly by the following method: First, obtain all the outlines of the beam model 1 (e.g., ...). Figure 1 Then, based on the characteristics of the top surface line 8, the filtering conditions for the top surface line 8 are set, and the top surface line 8 is obtained from all the contour lines of the beam model 1 (e.g., Figure 2 The top surface line 8 of the beam forms a rectangle. Then, arbitrarily select one of the long sides of the top surface line 8 and translate it along the direction of the short side of the top surface line 8 to the midpoint of the short side of the top surface line 8. The resulting line segment is the center line 2 of the top surface of the beam.

[0073] As a specific embodiment of the present invention, the selection criteria for the beam top line 8 are: the line located at the top of all contour lines, and the line whose height difference between the starting point and the ending point is within a preset range.

[0074] As a specific embodiment of the present invention, when a beam model file is loaded in a three-dimensional Cartesian coordinate interface with X-axis, Y-axis and Z-axis, and the height direction of beam model 1 is consistent with the Z-axis direction, the height of the points on the line is determined by the Z-axis coordinate when filtering the top surface line 8 of the beam.

[0075] In the above embodiment, the beam model is a cuboid. The height difference between the start and end points of the lines is within a preset range. Specifically, the height difference between the start and end points of the lines is very small, that is, the Z-axis coordinates of the start and end points are roughly the same (considering drawing errors, for example, the preset range is set to 2mm), indicating that these lines are located at the same height.

[0076] As a specific embodiment of the present invention, the beam model parameters include beam length, beam width, and beam height.

[0077] As a specific embodiment of the present invention, the existing steel reinforcement data file is located within the flat drawing.

[0078] As a specific embodiment of the present invention, the beam model file is obtained by performing beam analysis on the flat drawing.

[0079] As a specific embodiment of the present invention, the specifications of the reinforcing bars include the diameter of the reinforcing bars, the grade of the reinforcing bars, and the quantity of reinforcing bars.

[0080] This invention requires beam-related data and beam model 1 as basic data. Beam model 1 can be directly modeled, and beam-related data can be directly input. Alternatively, the basic data can be generated by analyzing existing flat surface drawings to obtain existing reinforcement data files.

[0081] The main principle of this invention is as follows: After obtaining the outline of beam model 1 and the centerline 2 of the top surface of the beam, three cross-sections are formed at both ends and the middle of the beam: a first cross-section, a second cross-section, and a third cross-section. These three cross-sections intersect with the outer outline of the beam to obtain the first beam cross-section, the second beam cross-section, and the third beam cross-section. Based on existing beam reinforcement data (such as the number and location information of longitudinal reinforcement), the intersection points of the beam longitudinal reinforcement with the first, second, and third beam cross-sections are obtained. These intersection points are designated as point steels 7, and each point steel 7 is assigned a corresponding reinforcement specification. Then, based on the centerline 2 of the top surface of the beam and the point steels 7, the original reinforcement line 6 is generated. The type of longitudinal reinforcement (continuous or non-continuous reinforcement) is determined based on the location information of the point steels 7, and corresponding processing is performed to obtain the final reinforcement line.

[0082] Figure 6 The diagram illustrates the generation of an initial rebar line 6. In this diagram, the three point steel bars 7 (DG1, DG2, and DG3) corresponding to the initial rebar line 6 are in the same relative position. If the rebar specifications of these three point steel bars 7 (DG1, DG2, and DG3) are the same, then... Figure 6 The original reinforcing bar line 6 in the diagram is the final reinforcing bar line.

[0083] like Figure 7-12 The diagram illustrates several cases where the longitudinal reinforcement is non-continuous, all of which do not meet the criteria for continuous reinforcement. In other words, the longitudinal reinforcement corresponding to point steel 7 is non-continuous, and the original reinforcement line 6 corresponding to this type of point steel 7 needs to be trimmed according to building code and standard drawings to obtain the final reinforcement line. Figure 7-12 9a, 9b, 9c, 9d, 9e, and 9f represent the final reinforcement lines under different conditions. Figures 7-12 In other words, the results after non-continuous reinforcing bars are cut under different circumstances.

[0084] The specific operation method for "cutting the original rebar line 6 corresponding to this type of point steel 7 according to the building code and drawing standards" is explained below: Figure 7 As shown, there are no point steels corresponding to the positions of point steels DG4 and DG5 on the third beam section enclosed by the third outer contour line 5. Therefore, it is necessary to cut off the original contour line passing through point steels DG4 and DG5, cutting off the section that intersects with the third beam section. The remaining part is the final reinforcement line 9a. The specific length and position of the cut can be determined according to the specification requirements.

[0085] Figure 13This refers to all the side structural reinforcement bars, which are generally continuous reinforcement bars (except for special beams).

[0086] Figure 14 It includes: upper longitudinal bars, lower longitudinal bars and side structural bars, wherein: the upper longitudinal bars are non-continuous bars, and the lower longitudinal bars and side structural bars are continuous bars.

[0087] Compared with existing technologies, the automatic reinforcement arrangement method for beam longitudinal bars of the present invention has the following advantages: The present invention provides a method for automatic reinforcement arrangement based on beam modeling, which can automatically arrange the longitudinal bars of the beam and provide the steel reinforcement specifications and attributes for subsequent longitudinal bars, which is beneficial for the rapid calculation of beam reinforcement. Using the method of the present invention, not only can the configuration of continuous reinforcement be completed, but it is also beneficial for the configuration of non-continuous reinforcement. Specifically, the present invention can complete the reinforcement arrangement of non-continuous bars by cutting the steel bars through multiple sections. This technology can also be applied to the configuration of longitudinal bars in variable cross-section beams and folded beams. Using the method of the present invention, the configuration of the bottom longitudinal bars, the side structural reinforcement, and the top longitudinal bars of the beam can be completed, expanding the reinforcement range and improving the efficiency and accuracy of automatic generation of beam longitudinal bars.

[0088] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can also refer to a "transmission connection," that is, a power connection through various suitable methods such as belt drive, gear drive, or sprocket drive. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
