[0054] As Figure 1 shown, the present application provides a method for realizing node deepening automation based on digital model, which comprises:

[0055] Step 1, establishing Revit model file, specifically comprising the following steps:

[0056] Step 1.1, establishing a steel bar, beam, column and wall structure model according to the design drawings of the building;

[0057] Here, two ways of drawing using software can be used.

[0058] The building may be, for example, a 2-story structure of a certain tower, including beams and steel bars, columns and steel bars, and shaped steel.

[0059] Step 1.2, establishing a steel structure shaped steel model according to the column and wall drawings of the building;

[0060] Here, three-dimensional modeling software can be used for drawing.

[0061] Step 1.3, merging the steel bar, beam, column, wall structure model and steel structure shaped steel model to obtain a merged model, and saving it as a Revit model file.

[0062] Step 2, processing the Revit model file using a plug-in to obtain a deepened Revit model file, specifically including the following steps:

[0063] Step 2.1, disassembling the steel bar group in the merged model and the merged model in the Revit model file to obtain a steel bar group and a steel structure shaped steel model group;

[0064] Step 2.2, regenerating and solidifying all single steel bars in the steel bar group to obtain solidified steel bars for subsequent collision detection;

[0065] Step 2.3, based on the solidified steel bars, performing collision detection between single steel bars, and performing positioning and bending operation deepening processing on the colliding steel bars;

[0066] Preferably, step 2.3.1, performing collision correction of main beam steel bars and secondary beam steel bars, after collision occurs between single steel bars, judging the main and secondary beams according to the characteristics of the beam and the size of the corresponding steel bars, moving the main beam steel bars downward or moving the secondary beam steel bars upward by a distance of one diameter d, i.e. directly placing the secondary beam steel bars on the main beam steel bars;

[0067] Step 2.3.2, performing collision correction of beam steel bars and column steel bars, after collision occurs, the column steel bars are not moved, but the beam steel bars which are less affected are made to turn left and right.

[0068] Step 2.4, performing collision detection between single steel bars and the steel structure shaped steel model group to complete the deepening processing of the shaped steel;

[0069] Preferably, step 2.4.1, if the steel bars collide with the web of the shaped steel, directly punching holes in the web, the punching size being, for example, Figure 2After the punching is completed, it is determined whether the strength requirement is still met. If the number of punches is too large, reinforcement is performed, and welding reinforcement is performed around the holes;

[0070] Specifically, the longitudinal reinforcement of the beam at the node should not pass through the flange of the profile steel, nor should it be directly welded to the profile steel. The longitudinal reinforcement in the beam should be as much as possible to penetrate the node, and the remaining longitudinal reinforcement can be reserved to penetrate the web of the column profile steel. The opening should be reserved in the factory processing, and on-site drilling is strictly prohibited. The commonly used reinforcement perforation hole diameter is recommended as Figure 2 The commonly used reinforcement perforation hole diameter (mm) is shown in the figure.

[0071] Step 2.4.2, when the reinforcement collides with the flange of the profile steel, the first choice is to connect the plate to connect and break the reinforcement, then according to the size of the reinforcement, determine the length of the connecting plate, and set the connecting plate on both sides of the flange, the height is one diameter d below the reinforcement penetrating the flange of the profile steel; For the same layer, the same height of a row of reinforcement corresponds to a pair of connecting plates, the size of the connecting plate is greater than 1.5 times the height of the beam section, and the thickness is greater than 0.7 times the web of the profile steel, as Figures 3 to 5 shown;

[0072] Specifically, as Figures 3 to 5 shown, 1 is a high-strength bolt, 2 is a welding area, 3 is a beam prefabrication and cast-in-place concrete interface, 4 is a connecting plate, 5 is a vertical stiffening plate, 6 is a steel pipe of a stiff column, 7 is a concrete wrapped around the stiff column, 8 is a beam concrete cover, lp is the length of the connecting plate;

[0073] The web of the I-shaped steel joint reserved by the stiff column and the hybrid beam should be connected by a connecting plate and a high-strength bolt, the connecting plate should be double, the thickness of each connecting plate should not be less than 0.7 times the thickness of the web of the I-shaped steel joint, and should not be less than 1 / 12 of the bolt spacing; The flanges should be welded by full penetration groove welding;

[0074] The sum of the lengths of the I-shaped steel joints of the stiff column and the hybrid beam L should not be less than the larger value of 0.16L and 1.3h, and should be less than 0.25L, L is the distance between the walls of adjacent stiff column steel pipes, and h is the height of the hybrid beam;

[0075] After the hybrid beam is connected with the stiff column, a closed stirrup should be tied at the I-shaped steel joint, the stirrup spacing should not be greater than 100mm, and the bar diameter should not be less than 8mm.

[0076] Step 2.4.3, when the reinforcement collides with the flange of the profile steel, the second choice is sleeve connection, the reinforcement is broken, then the sleeve is welded to the profile steel, and then the sleeve and the reinforcement are mechanically connected.

[0077] Here, unlike the connecting plate, the sleeve is welded at the same height as the corresponding steel bar, and the welding size is determined by the size of the corresponding steel bar, as shown in Figure 6

[0078] Step 2.4.4, for both the first and second connection modes, the steel bars are broken and the middle part of the steel bars is removed, so the middle part of the steel bars needs to be reinforced; for both connection modes, the insert is uniformly reinforced by the stiffening rib, the extension length and thickness of the stiffening rib are according to the standard, the length is equal to the web, the width is proportional to the flange, and the thickness is 0.75 times the thickness of the web.

[0079] Step 2.5, based on the deepened steel bars and steel, a deepened Revit model file is obtained.

[0080] Preferably, the insert includes the following modules:

[0081] The insert code writing module is used for users to modify, optimize and increase the insert by using C# language, so as to adapt to different needs of different users;

[0082] The insert packaging module is used for users to package the written code into an installation program, so as to be used for transfer and use of the insert;

[0083] The insert installation management module stores the packaged insert in the form of an installation program, so that users can execute the program to install and uninstall the insert, or use different versions of Revit;

[0084] The insert starting module is used for users to find the insert icon in the additional module through the SDK attached by Revit after executing the installation program, and start the insert through the icon;

[0085] The insert scene use module provides an operation interface for the insert, as described in step 2, the user can select one of the operations, which are steel bar disassembly operation, collision operation between steel bars, collision operation between steel bars and steel, and steel bar disassembly and solidification module for Revit steel bar model without entity development.

[0086] Step 3, export the deepened Revit model file into ifc2*3 format, save it, and then import it into a three-dimensional modeling software, so as to facilitate the deepening personnel to carry out the next deepening.

[0087] Specifically, the standards and specifications used by the present application can include the following:
