Description

Technical Field

[0001] This disclosure generally relates to the field of modeling technology, and specifically to an optimization method, apparatus, equipment and medium for the design of complex rebar nodes based on BIM. Background Technology

[0002] BIM (Building Information Modeling) technology is a technology for constructing and applying models that use graphics as a carrier and can load or associate numerous related engineering information.

[0003] In the construction of reinforced concrete structures, a large number of components require rebar tying for concrete pouring. Currently, rebar design and layout are primarily achieved using CAD drawings. There are three methods for representing reinforcement drawings of reinforced concrete structural members:

[0004] 1. Detailed drawing method: It shows the structural dimensions and reinforcement specifications of each component (beam, column, wall, etc.) through plan, elevation, and section drawings. The workload of drawing with detailed drawing method is very large.

[0005] 2. Beam-column table method: This method uses a table to express the structural dimensions and reinforcement specifications of structural members using numerical symbols. This method is much simpler and more convenient than the "detailed drawing method". It is very popular among designers when drawing by hand. Its disadvantages are: many data for similar members need to be filled in multiple times, which can easily lead to errors and omissions, and the number of drawings is large.

[0006] III. The overall planar design method for structural construction drawings directly represents the cross-sectional type, dimensions, and reinforcement specifications of structural members in the planar position of the members using numbers and symbols. It is then used in conjunction with the corresponding "General Structural Design Instructions" and the "General Construction Drawings and Instructions" for beams, columns, walls, and other members.

[0007] Because current design processes use specialized drawings, which are generally single-discipline 2D drawings, 3D collision detection is not possible. This leads to poor coordination between different steps, resulting in low efficiency, large workload, numerous drawing problems, long processing times, and a high risk of errors. This disadvantage is particularly pronounced for complex structures, large-scale projects, and projects with complex on-site construction conditions. It hinders the control of structural construction accuracy and the optimization of efficiency for construction companies. While parametric design methods have emerged that can quickly calculate 3D rebar nodes, they are only suitable for a limited range of node types and cannot accurately represent the detailed design layout of rebar nodes. This makes it impossible to effectively optimize node positions, and the applicability is severely limited.

[0008] Therefore, existing technologies need to be improved. Summary of the Invention

[0009] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an optimization method, device, equipment and medium for the design of complex rebar nodes based on BIM, which can meet the needs of the art.

[0010] Based on one aspect of the present invention, this application provides an optimization method for the design of complex rebar nodes based on BIM, the method comprising:

[0019] To determine the location of complex rebar nodes by obtaining the construction drawings of the building project, the location of complex rebar nodes includes relevant nodes on the construction drawings of the building project, such as the location of basement exterior walls, frame beams, transfer beams, steel beams, waterproof steel plates, and steel-concrete structural components.

[0020] Based on the construction drawings of the building project, the location of complex rebar nodes is determined, and BIM 3D modeling of concrete and steel structures is carried out.

[0029] By processing the steel bars at the bending points, collision points can be avoided;

[0030] Use structural reinforcement bars at the corners of the steel beams to ensure that the diameter of the tie bars for the stirrups is not less than the diameter of the stirrups.

[0033] Calculate the number of steel bars to be reduced based on the minimum vibration spacing of the steel bar arrangement and the minimum spacing required for the steel bar arrangement;

[0034] The proportion of reinforced concrete at the location of the reinforcing bar is determined by the stress coefficient at that location.

[0035] Based on the ratio of reinforced concrete at the location of the reinforcing bars, increase the diameter of the reinforcing bars at that location, or increase the number of rows of reinforcing bars to meet the stress conditions and concrete pouring requirements at that location.

[0036] In another embodiment, a solution to the problem of concrete not being able to be poured and compacted at the core node of the reinforced concrete structure due to additional reinforcement includes:

[0037] Calculate the tensile and compressive forces on the core nodes of the reinforced concrete structure and the concrete at its bottom, determine the strength of the concrete, and use self-compacting concrete that meets the stress conditions.

[0038] Calculate the solidification relationship between the joint between self-compacting concrete and conventional concrete, and determine the pouring volume of self-compacting concrete.

[0039] In another embodiment, the solution to the collision between the reinforcing bar and the steel structure includes:

[0040] The problem of collision between the steel reinforcement and the steel structure is solved by using a steel structure welded sleeve to connect the steel reinforcement. This includes:

[0041] Verify the consistency between the number of sleeves and the number of reinforcing bars, as well as the consistency between the sleeve diameter and the reinforcing bar diameter;

[0042] The portion where the reinforcing bar connects to the sleeve is machined into a thread structure that matches the thread of the sleeve.

[0043] Calculate the compressive and tensile strength of the steel structure at the welding point between the sleeve and the steel structure;

[0044] On both sides of the welded sleeve position of the steel structure, reinforced steel plates are installed, and the thickness of the reinforced steel plates is calculated according to the corresponding force to meet the force requirements of the steel structure at this position.

[0045] Alternatively, the problem of collision between the steel reinforcement and the steel structure can be solved by connecting the steel structure with welded stiffening plates, including:

[0046] Calculate the minimum welding length of the steel structure, ensuring that the length of the stiffening plate is not less than the minimum welding length;

[0047] Determine the strength of the concrete and use self-compacting concrete that meets the stress requirements;

[0048] Alternatively, the problem of collision between the steel reinforcement and the steel structure can be solved by directly inserting and lapping the steel reinforcement through the pre-drilled holes in the steel structure, including:

[0049] Calculate the opening ratio of the steel structure based on the number of openings;

[0050] Calculate the bending moment, shear force, constraint force, and material strength of the steel structure at the opening location;

[0051] Calculate the stress relationship after the opening is made in the steel structure, as well as the weakening relationship of the material strength, and increase the strength at the opening location;

[0052] Alternatively, a bent anchor method can be used to solve the problem of collision between the reinforcing bars and the steel structure, including:

[0053] Set the anchorage length and bend length of the reinforcing bars;

[0054] Calculate the concrete bond force at the connection point between the reinforcing bar and the steel structure's bent anchorage to ensure that the concrete bond force meets the requirements;

[0055] Alternatively, adding horizontal haunches to the beams can be used to avoid the steel reinforcement, allowing for direct anchoring after the reinforcement has cleared the steel structure. This solves the problem of collision between the reinforcement and the steel structure, including:

[0056] Calculate the avoidance angle of the reinforcing bar and determine the avoidance distance of the reinforcing bar;

[0057] Calculate the length-to-length ratio of the horizontal haunches on the beam, and set the diameter of the haunches reinforcement to be no less than the diameter of the reinforcement at the same location.

[0058] Based on another set of embodiments of the present invention, an optimization device for the design of complex rebar nodes based on BIM is disclosed, the device comprising:

[0059] The modeling module is used to determine the location of complex rebar nodes based on the construction drawings of the building project, and to create BIM 3D models of concrete and steel structures; based on the BIM 3D model and the rebar configuration information of the building project construction, it is used to create rebar layout models within the BIM 3D model.

[0060] The optimization module is used to restore the rebar layout modeling scene in the BIM 3D model to the actual on-site construction scene, and to find and solve the problems existing in the rebar layout modeling scene.

[0061] The simulation module is used to optimize the rebar layout modeling scenario based on identified problems, and to perform construction simulations for corresponding complex rebar nodes using the construction process of a building project. Based on the optimized rebar layout modeling scenario and the results of the construction simulations for the corresponding complex rebar nodes, construction animations are created for the BIM 3D model according to the simulation plan. The optimized rebar layout modeling scenario, the results of the construction simulations for complex rebar nodes, and the construction animations are then reviewed by multiple departments to obtain consistent construction drawings. Finally, BIM 3D modeling software is used to create a cloud model of the rebar layout modeling scenario, the results of the construction simulations for complex rebar nodes, the construction animations, and the consistent construction drawings, generating the final complex rebar node design model.

[0062] According to another aspect of the present invention, an electronic device is disclosed, the electronic device including one or more processors and a memory, the memory being used to store one or more programs; when the one or more programs are executed by the processor, the processor enables the processor to implement the optimization method for complex rebar node design based on BIM provided in the various embodiments of the present invention.

[0063] Based on another set of embodiments of the present invention, a computer-readable storage medium storing a computer program is disclosed, which, when executed, implements the optimization method for complex rebar node design based on BIM provided in various embodiments of the present invention.

[0064] In this embodiment, the location of complex rebar nodes is determined based on the construction drawings of the building project, and BIM 3D models of the concrete and steel structures are created. Based on the BIM 3D model and the rebar configuration information of the building project, the rebar layout within the BIM 3D model is modeled. The rebar layout modeling scene within the BIM 3D model is then recreated as a real-world construction scene, and problems existing in the rebar layout modeling scene are identified and resolved.

[0072] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0073] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0074] Please refer to Figure 1 It illustrates an exemplary flow of an optimization method for designing complex rebar nodes based on BIM, which can be applied to embodiments of this application.

[0075] like Figure 1 As shown, in step 110, the location of complex steel reinforcement nodes is determined based on the construction drawings of the building project, and BIM 3D modeling of concrete structure and steel structure is carried out.

[0076] Specifically, the construction of the BIM 3D model is mainly used to determine the location of complex rebar nodes based on the construction drawings of the building project. The main complex rebar node locations involved include the basement exterior walls, frame beams, transfer beams, steel beams, waterproof steel plates, and steel-concrete structural components.

[0077] Specifically, in one embodiment of this application, the step of determining the location of complex rebar nodes based on the construction drawings of the building project and performing BIM 3D modeling of the concrete structure and steel structure includes:

[0078] To determine the location of complex rebar nodes by obtaining the construction drawings of the building project, the location of complex rebar nodes includes relevant nodes on the construction drawings of the building project, such as the location of basement exterior walls, frame beams, transfer beams, steel beams, waterproof steel plates, and steel-concrete structural components.

[0079] Based on the construction drawings of the building project, the location of complex rebar nodes is determined, and BIM 3D modeling of concrete and steel structures is carried out. The parameters of the BIM 3D modeling include: wall thickness, beam and column section height, steel structure section size, steel structure anchor plate, steel structure sleeve, opening size, height parameters, sleeve thread direction, concrete coefficient, seismic grade coefficient, rebar protective layer parameters, and outer water-facing surface protection method.

[0080] Based on the on-site construction conditions and the steel reinforcement requirements marked in the construction drawings of the building project, BIM 3D modeling software is used to quickly convert 2D drawings into 3D models by utilizing the graphic conversion of the construction drawings of the building project.

[0081] Information is entered into the conversion model and the construction structure of the building project is set to ensure the integrity of the construction information and avoid errors in steel reinforcement calculation. For concrete construction, information such as concrete coefficient, seismic grade coefficient, steel reinforcement protective layer parameters, and protection methods for the outer water-facing surface must be complete.

[0082] For building construction projects with steel structures, a 3D model of the steel structure should be created to facilitate collision detection and arrangement of the 3D model of the reinforcing bars. The model of the reinforcing bar hooks should be created according to the detailed drawings to ensure that the positions of relevant components such as anchors, corbels, and electromechanical reserved holes in the model are correct, so as to facilitate collision detection with the reinforcing bar model.

[0083] The locations of additional rebar sleeves, steel structure openings, and rebar anchor plates at node locations should be checked against the rebar model to ensure that the location, quantity, and height are consistent with the rebar model. The dimensions of openings and rebar sleeves should be checked to ensure they are consistent with the rebar. The thread direction should be marked in the model. After the steel structure components arrive on site, a designated person should inspect them to ensure that the lap joints of the components meet the specifications after installation.

[0084] In step 120, the steel reinforcement layout model is performed in the BIM 3D model based on the BIM 3D model and the steel reinforcement configuration information of the building project.

[0085] Specifically, after completing the BIM 3D model of the building structure design, the reinforcement layout model should be carried out based on the reinforcement information in the construction drawings of the building project. The specific reinforcement type, diameter, length, lap splice type, lap splice length, anchorage type, and anchorage length information should be reflected in the reinforcement layout model drawing.

[0086] An automated modeling process for rebar layout can be designed and built using existing visual programming platforms, integrating the attribute information of 3D graphic objects with construction design information to achieve efficient and parametric creation of rebar graphic objects.

[0087] Specifically, in one embodiment of this application, the step of determining the location of complex rebar nodes based on the construction drawings of the building project and performing BIM 3D modeling of the concrete structure and steel structure includes:

[0088] To determine the location of complex rebar nodes by obtaining the construction drawings of the building project, the location of complex rebar nodes includes relevant nodes on the construction drawings of the building project, such as the location of basement exterior walls, frame beams, transfer beams, steel beams, waterproof steel plates, and steel-concrete structural components.

[0089] Based on the construction drawings of the building project, the location of complex rebar nodes is determined, and BIM 3D modeling of concrete and steel structures is carried out. The parameters of the BIM 3D modeling include: wall thickness, beam and column section height, steel structure section size, steel structure anchor plate, steel structure sleeve, opening size, height parameters, sleeve thread direction, concrete coefficient, seismic grade coefficient, rebar protective layer parameters, and outer water-facing surface protection method.

[0090] In step 130, the rebar layout modeling scene in the BIM 3D model is restored to the actual on-site construction scene, and the problems existing in the rebar layout modeling scene are identified and resolved.

[0091] Specifically, the rebar layout modeling scene in the BIM 3D model is restored to the actual on-site construction scene. The actual construction situation is viewed in the actual construction scene, and problems with rebar layout and construction are found. The corresponding rebar problems are analyzed and solved.

[0092] Specifically, in one embodiment of this application, the step of restoring the rebar layout modeling scene in the BIM 3D model to a real on-site construction scene, and identifying and resolving problems existing in the rebar layout modeling scene, includes:

[0093] Solution to the problem of main reinforcing bars at the corner of steel beams not being properly anchored into the support;

[0094] Solutions to problems caused by insufficient steel reinforcement density preventing concrete from being poured and compacted;

[0095] Solutions for situations where concrete cannot be poured and compacted at core joints of reinforced concrete structures due to additional reinforcement.

[0096] Solutions to collisions between reinforcing bars and steel structures.

[0097] Specifically, the solutions to the problem of the main reinforcing bars at the corner of the steel beam not being properly anchored into the support include:

[0098] The bending avoidance distance of the main reinforcement of the steel beam is determined by calculating the size of the main reinforcement of the steel beam and the support column.

[0099] The bending angle of the reinforcing bar is calculated to determine and mark the bending position of the reinforcing bar.

[0100] By processing the steel bars at the bending points, collision points can be avoided;

[0101] Use structural reinforcement bars at the corners of the steel beams to ensure that the diameter of the tie bars for the stirrups is not less than the diameter of the stirrups.

[0102] Specifically, the main reinforcement of the beam is calculated according to the size of the beam and column reinforcement, the bending avoidance distance of the main reinforcement is determined, the bending position of the reinforcement is determined by calculating the bending angle of the reinforcement and marked, the reinforcement is processed after the bending position of the reinforcement is determined, collision avoidance is carried out, the bending angle of the reinforcement is considered, and structural reinforcement should be provided at the corner of the beam to ensure that the diameter of the tie reinforcement of the beam stirrup is not less than the diameter of the stirrup.

[0103] Specifically, the solutions to the problem of concrete not being able to be poured and compacted due to the aforementioned steel reinforcement density include:

[0104] Calculate the maximum diameter of concrete aggregate and the diameter of concrete vibrator according to the concrete grade, and determine the minimum vibration spacing of the reinforcing bars.

[0105] Calculate the number of steel bars to be reduced based on the minimum vibration spacing of the steel bar arrangement and the minimum spacing required for the steel bar arrangement;

[0106] The proportion of reinforced concrete at the location of the reinforcing bar is determined by the stress coefficient at that location.

[0107] Based on the ratio of reinforced concrete at the location of the reinforcing bars, increase the diameter of the reinforcing bars at that location, or increase the number of rows of reinforcing bars to meet the stress conditions and concrete pouring requirements at that location.

[0108] Specifically, due to the high density of steel reinforcement, the concrete cannot be fully poured and compacted. The reinforcement of frame beams, transfer beams, beams with columns, and beams at various locations is relatively large, and the number of reinforcement bars in the upper part of the beams is large, resulting in small spacing between the steel bars. The vibrator cannot penetrate deeply into the structure, and the concrete is not properly vibrated, resulting in a lack of compaction. In severe cases, voids will appear in the concrete, affecting the concrete strength and significantly impacting the quality of the concrete. At the same time, the dense reinforcement can lead to concrete segregation, causing the concrete cementitious materials (mainly cement) to separate from the aggregates (sand and gravel). This results in voids and a lack of compaction in the concrete, causing the concrete strength grade to fail to meet requirements, which will greatly affect the quality of the concrete. Consequently, it will also greatly affect the stress between the concrete and the steel reinforcement, creating potential safety hazards for the overall structure.

[0109] The solution for this situation is as follows: Calculate the spacing of the reinforcing bars, the maximum diameter of the aggregate and the diameter of the vibrator according to the concrete grade, and determine the minimum vibration spacing for the reinforcing bars. Reduce the number of reinforcing bars according to the minimum spacing, calculate the compressive strength coefficient of the reinforcing bars in that layer, determine the ratio of reinforcing bars to concrete at that location, and increase the diameter of the reinforcing bars or the number of rows of reinforcing bars at that location according to the calculation results to meet the stress conditions and concrete pouring requirements at that location.

[0110] Specifically, the solutions to the problem of concrete not being able to be poured and compacted at the core node of the reinforced concrete structure due to additional reinforcement include:

[0111] Calculate the tensile and compressive forces on the core nodes of the reinforced concrete structure and the concrete at its bottom, determine the strength of the concrete, and use self-compacting concrete that meets the stress conditions.

[0112] Calculate the solidification relationship between the joint between self-compacting concrete and conventional concrete, and determine the pouring volume of self-compacting concrete.

[0113] Specifically, due to the additional reinforcement at the core nodes of the steel-concrete structure, the concrete cannot be fully poured and compacted. At the core nodes of the steel-concrete column-beam joints, the addition of anchor plates prevents the vibrator from reaching the structure, resulting in inadequate concrete vibration. This leads to a lack of compaction in the concrete, and in severe cases, voids may appear in the concrete, affecting its strength and significantly impacting its quality.

[0114] The solution to this situation is as follows: For the concrete at the rebar joint, calculate the tensile and compressive forces on the concrete at that location and at the bottom, determine the concrete strength, and replace it with self-compacting concrete that meets the stress conditions. Calculate the solidification relationship between the self-compacting concrete and the conventional concrete at the joint location, and calculate and determine the volume of self-compacting concrete to ensure the construction quality at that location.

[0115] Specifically, when the reinforcing bars collide with the steel structure, they need to be connected to the steel structure. The connection method is selected according to the location of the collision between the steel structure and the reinforcing bars. The solutions for the collision between the reinforcing bars and the steel structure include five methods: first, sleeve connection; second, stiffening plate connection; third, through hole; fourth, reinforcing bar bending and anchoring; and fifth, adding haunches to avoid the steel components.

[0116] Specifically, one approach is to use a steel structure welded sleeve to connect with the reinforcing bars, thus resolving the issue of collisions between the reinforcing bars and the steel structure. This includes:

[0117] Verify the consistency between the number of sleeves and the number of reinforcing bars, as well as the consistency between the sleeve diameter and the reinforcing bar diameter;

[0118] The portion where the reinforcing bar connects to the sleeve is machined into a thread structure that matches the thread of the sleeve.

[0119] Calculate the compressive and tensile strength of the steel structure at the welding point between the sleeve and the steel structure;

[0120] On both sides of the welded sleeve position of the steel structure, reinforced steel plates are installed, and the thickness of the reinforced steel plates is calculated according to the corresponding force to meet the stress requirements of the steel structure at this position.

[0121] Specifically, when connecting steel structure welded sleeves to reinforcing bars, it is important to verify that the number of sleeves matches the number of reinforcing bars, and that the sleeve diameter matches the reinforcing bar diameter. On-site threading of the reinforcing bars should be performed to match the sleeve threads to avoid installation problems. It is necessary to prevent uneven stress on both sides of the welded sleeve location, which could weaken the static load strength. At the welded sleeve location on the steel column, the compressive and tensile strengths of the reinforcing bars at the sleeve location should be calculated to determine the relationship between the static load strength and the weakening of the tensile strength of the steel column at that location. Based on this relationship, reinforcing steel plates should be installed on both sides of the welded sleeve location. The thickness of the reinforcing steel plates should be calculated based on the corresponding stress relationship to ensure the steel column can withstand the stress at that location.

[0122] When both sides of the beam reinforcement are connected by sleeves, if the reinforcement cannot be mechanically connected normally, it can be disconnected and then lapped using an electroslag pressure welded joint, or a double threaded sleeve lapped joint can be used.

[0123] Specifically, the second method involves connecting steel structure welded stiffening plates to reinforcing bars to solve the problem of collisions between reinforcing bars and steel structures, including:

[0124] Calculate the minimum welding length of the steel structure, ensuring that the length of the stiffening plate is not less than the minimum welding length;

[0125] Determine the strength of the concrete and use self-compacting concrete that meets the stress requirements.

[0126] Specifically, when connecting steel structure welded stiffening plates to reinforcing bars, it's crucial to ensure that the minimum weld length for the reinforcing bars is not less than the minimum weld length. Adding stiffening plates to steel columns may prevent vibrators from penetrating the core area of ​​the joint, potentially leading to insufficient concrete compaction. In such cases, self-compacting concrete should be used at the reinforcing bar joint location to guarantee construction quality. If multiple rows of main reinforcing bars exist, only one layer of stiffening plates should be installed. Multiple rows may result in insufficient spacing between the plates, preventing adequate concrete filling and hindering welding of the reinforcing bars.

[0127] Specifically, the third method involves using steel reinforcement bars with pre-drilled holes to directly pass through the steel structure and anchor them in a normal lap splice manner to solve the problem of collision between the reinforcement bars and the steel structure. This includes:

[0128] Calculate the opening ratio of the steel structure based on the number of openings;

[0129] Calculate the bending moment, shear force, constraint force, and material strength of the steel structure at the opening location;

[0130] Calculate the stress relationship after the opening is made in the steel structure, as well as the weakening relationship of the material strength, and increase the strength at the opening location.

[0131] Specifically, for steel structures with perforated reinforcing bars, normal anchoring and lap splicing can be performed directly through the steel structure. The perforation rate of the steel structure is calculated based on the number of perforations. The bending moment, shear force, constraint force, and material strength at the perforation location are calculated. The stress relationship and material strength weakening relationship of the steel structure after perforation are calculated based on the perforation location. Appropriate reinforcement should be added at the perforation location of the steel member. When some stirrups and tie bars are perforated through the perforations in the steel structure, care should be taken to ensure that conventionally processed 180-degree rebar hooks cannot pass through normally. One side should be processed into a 90-degree hook, and after the steel structure is perforated, it should be processed into a 180-degree hook again.

[0132] Specifically, fourthly, a bent anchor method is used to solve the problem of collision between the reinforcing bars and the steel structure, including:

[0133] Set the anchorage length and bend length of the reinforcing bars;

[0134] Calculate the concrete bond force at the connection points between the reinforcing bars and the steel structure's bent anchorages to ensure that the concrete bond force meets the requirements.

[0135] Specifically, when reinforcing bars collide with steel structures and cannot be directly anchored, if the requirements for bent anchoring are met, bent anchoring can be performed directly. The remaining straight anchorage length after bending should be greater than 0.4 times the total straight anchorage length, and the bending length should be no less than 15 times the diameter of the reinforcing bar. The concrete bond strength at that location should also be calculated. When frame beams are supported by frame columns, it is important to note that, according to design specifications, while meeting the requirement of a straight anchorage length of 0.4 times the diameter of the reinforcing bar, the anchorage length should exceed 5 times the diameter of the reinforcing bar at the column centerline.

[0136] Specifically, fifthly, the reinforcement is avoided by adding horizontal haunches to the beams, and then directly anchored after avoiding the steel structure, thus solving the problem of collision between the reinforcement and the steel structure. This includes:

[0137] Calculate the avoidance angle of the reinforcing bar and determine the avoidance distance of the reinforcing bar;

[0138] Calculate the length-to-length ratio of the horizontal haunches on the beam, and set the diameter of the haunches reinforcement to be no less than the diameter of the reinforcement at the same location.

[0139] Specifically, when the main reinforcement of the beam collides with the steel column, horizontal haunches can be added to the beam to avoid the collision. After avoiding the steel structure, direct anchoring can be performed. The avoidance angle of the reinforcement is calculated to determine the avoidance distance. Horizontal haunches can only be added if the avoidance distance is less than the distance from the beam edge to the column edge. The ratio of the long side to the short side of the haunch should not exceed 1:4. Haunches should be reinforced with additional reinforcement, and the diameter of the haunch reinforcement should not be less than that of the reinforcement at the same location. The stress in the concrete at the location where the beam reinforcement avoids collision should be calculated to determine if it is too high. If stress concentration occurs at this location, structural reinforcement should be added to avoid stress concentration.

[0140] In step 140, based on the problems found in the rebar layout modeling scenario, the rebar layout modeling scenario is optimized, and the construction process of the building project is used to simulate the construction of the corresponding complex rebar nodes.

[0141] Specifically, depending on the construction scenario of a complex rebar joint, for example: First, the main reinforcement of the first column is cut off and collides with the steel beam, using a reinforced plate welded connection. Second, at the complex rebar joint, the column stirrups collide with the steel beam corbel; in this area, the stirrups need to be cut and welded to the connecting plate. Third, the beam reinforcement collides with the steel structure column; the lap splicing method is selected according to relevant conditions. Fourth, the main reinforcement is connected by a welded sleeve; at this location, the connection between the welded sleeve and the beam main reinforcement should be calculated based on the weakening relationship between static load strength and tensile strength, and reinforcing steel plates should be added on both sides of the welded sleeve location. Fifth, the connecting plate is welded to the steel column. Sixth, the beam reinforcement needs to have its bending anchor position adjusted or bend appropriately before being anchored into the joint, depending on the joint situation. Through the above methods, construction simulation scenarios for complex rebar joints can be constructed.

[0142] In step 150, based on the optimized rebar layout modeling scenario and the construction process of the building project, the construction simulation results of the corresponding complex rebar nodes are used to create a construction animation for the BIM 3D model according to the construction simulation plan.

[0143] Specifically, for the optimized rebar layout modeling scenario and the construction simulation results of the corresponding complex rebar nodes in the construction project process, professional graphics and video software is used to create a construction animation for the 3D model according to the construction simulation plan. The video construction plan should be consistent with the construction simulation plan to complete a construction guidance animation that is consistent with the on-site process.

[0144] In step 160, the optimized rebar layout modeling scenario, the construction simulation results of complex rebar nodes, and the construction animation production results are reviewed by multiple departments to obtain consistent construction drawings.

[0145] Specifically, the optimized rebar layout modeling scenario, the construction simulation results of complex rebar nodes, and the construction animation production results are subject to multi-departmental collaborative review. The design, supervision, and construction departments conduct the review to ensure consensus is reached, and then the corresponding construction drawings and instructions are issued.

[0146] In step 170, BIM 3D modeling software is used to create a cloud model of the rebar layout modeling scenario, the construction simulation results of complex rebar nodes, the construction animation production results, and the consistent construction drawings, generating the final complex rebar node design model.

[0147] Specifically, BIM 3D modeling software is used to create a cloud model of the rebar layout modeling scenario, the construction simulation results of complex rebar nodes, the construction animation production results, and the consistent construction drawings. The BIM system software automatically generates graphic QR codes so that the 3D model, construction animation, and related drawings and instructions can be directly viewed on the construction site by scanning the QR codes with a mobile device.

[0148] The functional graphic object of this application is a three-dimensional geometric graphic object in a graphics system. It can be selected, moved, copied, enlarged, and reduced in geometric operations. It is necessary to customize special engineering attributes and professional functions for the functional object. The operation interface of the functional graphic object can be activated by the mouse, which displays the relevant attribute information or parameter information of the functional graphic object, as well as some operation buttons to realize professional functions.

[0149] The functional 3D graphic objects of this application can be obtained through parametric and forced conversion methods. For simple functional graphic objects, parametric modeling can be used, which means that the required functional graphic object can be created by entering a certain number of parameters; for complex functional graphic objects, forced conversion can be used.

Different outputs can be generated by inputting different parameter data. It can integrate the attribute information of 3D graphic objects with construction design information, build an automated modeling process, and realize the rapid conversion between 2D graphic information and 3D models.

It allows for a systematic, collaborative, efficient, and professional approach to rebar node optimization, simplifying and facilitating the design and layout of rebar node optimization schemes and the simulation of the construction process, thus contributing to the potential and efficiency improvement of construction projects.

It simplifies and improves the efficiency of rebar joints. It has a wide range of applications and is conducive to the safety control and precise quality control of rebar construction in building projects, thus promoting the development of intelligent construction technology in building projects.
