Description

TECHNICAL FIELD

[0001] The application belongs to the field of building information model construction, and particularly relates to a building rectangular structure column reinforcement framework parameterized modeling method and device. BACKGROUND

[0002] In the field of building information model (BIM) technology, Revit is a mainstream design tool, and two technical routes are generally adopted in the industry to realize reinforcement modeling: one is to create a parameterized reinforcement component family, to realize the parameterized driving of the model and the automatic statistics of the engineering quantity by predefining the reinforcement form and nesting it into the main component; and the other is to use a visual programming platform to quickly generate a reinforcement center line and a model by reading an external data table and driving the component edge line to perform geometric offset. These methods aim to improve modeling efficiency and to a certain extent solve part of the modeling problems of complex components.

[0003] However, in the above prior art, the parameterized family method can realize automatic statistics of engineering quantity, but the reinforcement arrangement mode is fixed in the family creation stage and cannot be adaptively adjusted according to specific reinforcement marking or structural specification requirements, and it is difficult to handle the intelligent association between longitudinal reinforcement and stirrup. The data-driven method of the visual programming platform improves the modeling speed, but the reinforcement arrangement seriously depends on the data table prepared by artificial pre-processing, which not only has a large workload, but also is prone to inconsistency between data and model when the model changes. At the same time, the above methods cannot automatically identify the spatial relationship of the structural column in the overall model (such as the difference between the side column, the corner column and the middle column) and the node position (such as the top layer, the intermediate layer and the embedded end), so they cannot convert complex design rules such as the Concrete Structure Design Specification (GB50010), the Building Seismic Design Specification (GB50011) and the G101 flat method atlas into algorithm logic, realize the automation and compliance judgment of reinforcement anchoring, connection and bending, and finally still need to rely on manual intervention for correction, which is difficult to truly realize the intelligentization and automation of the whole process.

[0007] Further, the calculation of the plane coordinates of the longitudinal reinforcement includes the following steps: The orientation of the structural column model is obtained, the direction vector of the structural column section long side is taken as the orientation of the structural column model, and the direction vector of the current structural column section short side is obtained by cross multiplication of the vector and the Z-axis direction; The plane coordinates of the four corner points of the building rectangular structural column are calculated by offsetting the center coordinates of the structural column bottom to the structural column section long side and short side by half the structural column section long side and half the structural column section short side, respectively; After offsetting the plane coordinates of the four corner points of the structural column to the interior of the structural column by the distance of the protective layer thickness in the global parameters plus the corner reinforcement radius according to the direction vectors of the structural column section long side and short side, the two-dimensional center coordinates of the corner reinforcement actually arranged on the structural column are calculated; According to the reinforcement quantity of the structural column section long side and short side specified by the reinforcement information, the longitudinal reinforcement points are evenly arranged between the adjacent corner reinforcements, which are used as the two-dimensional center coordinates of the longitudinal reinforcement middle reinforcement.

[0008] Further, the establishment of the longitudinal reinforcement model includes the following steps: After calculating the two-dimensional center coordinates of the longitudinal reinforcement, the height of the current structural column is taken as a reference to determine the coordinate points of the starting point and the ending point of the longitudinal reinforcement; The longitudinal reinforcement is subjected to collision test; According to the collision test result and the structural column attribute in the global parameter, it is judged whether the member connected with the top / bottom of the structural column is a beam, a plate or a foundation structure model; According to the mounting specification of the top / bottom of the structural column and the beam, the plate and the foundation structure, the bending anchoring modeling and the size of the longitudinal reinforcement end are set, and the longitudinal reinforcement is staggered according to the anchoring length in the global parameter, so as to complete the three-dimensional modeling of the longitudinal reinforcement.

[0011] Further, the Z-axis binding path planning of the stirrup comprises the following steps: When the stirrup point moves along the structural column section long side, the Z-axis coordinate of the next path point is added by a diameter value of the stirrup; When the stirrup point moves along the short side of the structural column section, the Z-axis coordinate of the next path point is reduced by the diameter value of one stirrup; wherein the Z-axis coordinate of the starting point is 0.

[0012] Further, before constructing the longitudinal reinforcement three-dimensional model, it is judged whether the structural column is a corner column, which comprises the following steps: The boundary contour of the floor and the bottom center coordinate point of each structural column are read, and the projection distance of the structural column to the boundary contour of the floor is calculated; It is judged whether the projection distance is less than the set threshold value, if less than or equal to the set threshold value, it is determined that the structural column is a corner column, if greater than the threshold value, it is determined that the structural column is not a corner column; The judgment result is written into the structural column parameters.

[0026] Wherein, the parsing of regular expression and the marked string are all prior art, and the specific steps can refer to the following steps: S3-1, create a general flat method mark for matching common types of steel flat method marks, such as the code Regular matching is performed, and the code Regular matching is performed.

[0031] Different regular expression patterns are written in advance according to the flat method atlas rules, such as matching 4C20, A12@100 / 200, etc. The steel reinforcement quantity, grade, diameter, spacing and other key information in the reinforcement parameter can be automatically scanned and accurately captured, and the information is converted into structured data, which avoids the errors caused by manual data entry and the risk of inconsistent model and drawing.

[0032] S4, based on the structural column section size and reinforcement data in the geometric properties of the structural column model, the plane coordinates of the longitudinal reinforcement are calculated through the model vector and interpolation algorithm, and whether the structural column is an edge corner column is judged, and the judgment method includes the following steps: Read the boundary contour of the floor and the bottom center coordinate point of each structural column, and calculate the projection distance of the structural column to the floor boundary contour.

[0033] Determine whether the projection distance is less than the set threshold value, if less than or equal to the set threshold value, it is determined that the structural column is an edge corner column, if greater than the threshold value, it is determined that the structural column is not an edge corner column.

[0034] The judgment result is written into the structural column parameter.

[0035] According to the plane coordinates of the longitudinal reinforcement, the longitudinal reinforcement model is established on the surface of the structural column.

[0036] The calculation of the plane coordinates of the longitudinal reinforcement includes the following steps: S4-1, obtain the orientation of the structural column model, take the structural column model orientation as the direction vector of the long side of the structural column section, and then cross multiply the vector and the Z-axis direction to obtain the direction vector of the short side of the current structural column section.

[0037] S4-2, take the center of the bottom of the structural column as the origin of the coordinate system, and then calculate the coordinates of the four corner points of the structural column according to the direction vectors of the long side and the short side of the structural column section.

[0038] S4-3, offset the plane coordinates of the four corner points of the structural column to the inside of the structural column by a distance of the protection layer thickness plus the radius of the stirrup according to the direction vectors of the long side and the short side of the structural column section, and then calculate the two-dimensional center coordinates of the stirrup actually arranged on the structural column in the longitudinal reinforcement.

[0039] S4-4, according to the reinforcement quantity of the long side and the short side of the structural column section, evenly set the longitudinal reinforcement points between adjacent stirrups by interpolation algorithm, and take them as the two-dimensional center coordinates of the side reinforcement in the longitudinal reinforcement.

[0040] The establishment of the longitudinal reinforcement model includes the following steps: S4-5, after calculating the two-dimensional center coordinates of the longitudinal reinforcement, take the height of the current structural column as a reference to determine the coordinate points of the starting point and the ending point of the longitudinal reinforcement, and stagger the arrangement of the longitudinal reinforcement according to the anchoring length.

[0041] S4-6, perform collision test on the longitudinal reinforcement, which includes the following steps: A 3m long, wide and high bounding box is established with the center of the column bottom surface as the center, and then the bounding box is used to determine whether there are related components. The top is the same.

[0042] S4-7, according to the collision test results and the properties of the structural column, determine whether the components connected to the top / bottom of the structural column are beams, plates or foundation structures.

[0043] S4-8, set the bending anchoring modeling and size of the end of the longitudinal reinforcement according to the installation specifications of the top / bottom of the structural column and the beams, plates and foundation structures, complete the three-dimensional modeling of the longitudinal reinforcement, and when the structural column is not a corner column, use the conventional anchoring of the longitudinal reinforcement, and calculate the anchoring length of the bottom of the longitudinal reinforcement according to the collision detection of the underlying foundation.

[0044] When the structural column is a corner column, the column anchor beam structure is applied at the corner position of the corner column during modeling of the longitudinal reinforcement, including the following steps: Obtain the four side surfaces of the structural column judged as a corner column, determine how many side surfaces are in contact with the beam model in the building information model, and determine that the side surface not in contact with the beam model in the building information model is facing the outside of the building information model.​​

[0045] When there are two edges facing the outside of the structure, the corresponding steel bars of the two edges are calculated with a length of 1.5Laewith the bottom of the beam as the starting point. The remaining column edge steel bars are extended to the top of the structure column and then bent by 12d.

[0046] S5, calculate the three-dimensional coordinates of each stirrup at the binding points on the longitudinal reinforcement according to the irregular stirrup circular winding method, and perform three-dimensional modeling of the stirrup according to the binding point coordinates.

[0047] The irregular stirrup circular winding method includes the following steps: S5-1, optionally select a structural column corner reinforcement planar coordinate point as the path starting point, and extract all longitudinal reinforcement points in the direction of the long side and short side of the structural column section at the same height as the path starting point to form a to-be-processed list respectively.

[0048] S5-2, combine the directions of the long side and short side of the structural column section, and arrange the longitudinal reinforcement points in the to-be-processed list in order from near to far starting from the path starting point.

[0049] S5-3, starting from the path starting point, horizontally plan the path of the to-be-processed stirrup points in the long side and short side of the structural column section according to the set processing order.

[0050] Please refer to Figure 2 , the horizontal path planning method of the stirrup point is as follows: S5-3-1, determine the number of remaining longitudinal reinforcement points in the to-be-processed list. When the number of points is greater than 2, extend the stirrup from the current stirrup point to the first longitudinal reinforcement point, and then wrap around the second longitudinal reinforcement point. Record the planar coordinates of the stirrup after wrapping around the second longitudinal reinforcement point.

[0051] S5-3-2, remove the longitudinal reinforcement points that have been in contact with the stirrup from the to-be-processed list.

[0052] S5-3-3, repeat the above process until the number of remaining longitudinal reinforcement points in the list is no longer greater than 2.

[0053] S5-3-4, when the number of remaining longitudinal reinforcement points in the to-be-processed list is equal to 2, calculate the path from the current stirrup point to the last two longitudinal reinforcement points, form a rectangular stirrup, and return to the starting point of the entire path. Record the winding path of the last two longitudinal reinforcement points, and generate a coordinate point with an angle of 135° between the stirrup based on the planar coordinates of the last longitudinal reinforcement point.

[0054] S5-3-5, when the number of longitudinal reinforcement points is equal to 1, the planned path starts from the current stirrup point and winds around the last longitudinal reinforcement point to form an L-shaped bent stirrup, the planar coordinates of the point are recorded as the corner point, a coordinate point with an angle of 135° between the stirrup is generated, and finally a top view like the stirrup structure shown in Figure 2 is formed, Figure 3 is a stirrup structure with longitudinal reinforcement.

[0055] S5-4, path planning of the stirrup point in the Z-axis direction, including the following steps: S5-4-1, when the stirrup point moves along the long side of the structural column section, the Z-axis coordinate of the next path point is increased by the diameter value of the stirrup.

[0056] S5-4-2, when the stirrup point moves along the short side of the structural column section, the Z-axis coordinate of the next path point is decreased by the diameter value of the stirrup.

[0057] wherein the Z-axis coordinate of the starting point is 0, and the planning of the stirrup horizontal plane path and the height path can be performed synchronously.

[0058] The algorithm used in this step takes the longitudinal reinforcement coordinate as the reference point, dynamically judges the number of points by traversing the longitudinal reinforcement point list in the B and H directions, and correspondingly adopts the winding, rectangular bent stirrup or L-shaped bent stirrup strategy to automatically generate the accurate three-dimensional path coordinates of the stirrup. This method can adapt to any longitudinal reinforcement configuration and efficiently solves the core pain points of manual creation of special-shaped stirrups in Revit, which is difficult and low in efficiency.

[0059] S6, aligning the structural column reinforcement of different floors, and according to the connection area height required by the national standard specification, disconnecting the longitudinal reinforcement at the position meeting the connection area height requirement, and adding a connecting head for connecting longitudinal reinforcements of different heights at the disconnected position of the longitudinal reinforcement, to complete the modeling of the building rectangular structural column reinforcement skeleton.

[0060] Specifically, S6 includes the following steps: S6-1, obtaining all the longitudinal reinforcements corresponding to the structural columns, and pairing the upper and lower structural columns in units of floors.

[0061] S6-2, after finding the mutually paired structural columns, matching the connection between the longitudinal reinforcements according to the coordinate positions of each longitudinal reinforcement.

[0062] S6-3, after matching, matching the mechanical connecting head with the corresponding diameter according to the diameters of the upper and lower longitudinal reinforcements, and calculating the Z-axis coordinate of the joint based on the Z value of the center coordinate of the structural column bottom as the reference point after calculating the longitudinal reinforcement joint height according to the longitudinal reinforcement diameter, wherein the reinforcement joint height is 35d, and d is the diameter of the longitudinal reinforcement.

[0063] S6-4, take the calculated longitudinal reinforcement one end point coordinate, X, Y keep unchanged Z is the height of the joint as the coordinate of the joint, the original longitudinal reinforcement takes the coordinates of two end points and the coordinates of the joint to split into two longitudinal reinforcements, if the upper and lower steel diameters are different, the variable cross-section joint family is used to connect and install.

[0064] In practical application, there are three common steel connection methods between floors, which are binding lap joint, mechanical connection and welding connection.

[0065] The following will expand the algorithm around the mechanical connection method.

[0066] In the embedded floor, such as the first underground floor, the area above Hn / 3 (one-third net height) is defined as the connection area, and in other floors, the maximum value of Hn / 6, Hc (the maximum side length of the column) and 500mm is defined as the steel connection area, but in order to meet the operation habit of construction personnel and avoid workers working on the ground, it is a common practice to set the steel connection area in an area above 1000mm.

[0067] Please refer to Figure 4 , the application defaults the steel of the standard floor to two parts for steel mechanical connection, one part is located at the position of 1000mm above the floor, and the other part is located at the position of 1000mm+35d (steel diameter) above the floor, which not only meets the 50% stagger rate of steel (G101-1-P59), but also meets the longitudinal steel structure connection requirements of the frame column (G101-1-P63).

[0068] The embodiment establishes a complete automatic workflow, from reading the model, analyzing the annotation, calculating the coordinates to generating the entity model and the connection head, completely without manual intervention in the model creation process, and converts the “Concrete Structure Design Specification” (GB50010), G101 atlas and actual construction experience into executable algorithm logic.

[0069] The application also provides buttons for controlling the display style of the steel, such as entity display, non-entity display, and semi-transparent steel, so that the operator can quickly adjust the display style of the steel using the Revit API, and improve the user experience.

[0070] Specifically, entity display: all steels are solidified for viewing.

[0071] Non-entity display: for computer performance considerations, all steels are simplified to line display.

[0072] Semi-transparent component: the components of the structural column specialty are virtualized to 50% transparent entities, which facilitates the viewing of the position of the structural column and the arrangement of the steel.

[0073] Clean up the reinforcement: remove all the generated reinforcement.
