Description

Technical Field

[0001] The invention relates to a method and system for generating a hyperbolic concrete shell structure formwork keel model. Background Art

[0002] Building Information Modeling (BIM) is a new tool in architecture, engineering, and civil engineering. Compared to traditional CAD two-dimensional drawing and design methods, BIM-assisted construction can significantly reduce various errors made by design team members in the early stages of the construction design of hyperbolic thin shell systems, and can also reduce errors made by subsequent contractors. This can reduce construction time and also help reduce project costs. Currently, BIM design technology has been widely used in the field of reinforced concrete structure construction and is increasingly penetrating into various fields of construction.

[0003] In more complex building components, such as formwork design for concrete pouring, scaffolding system design and building curtain wall design, although there are some attempts at BIM design, there are relatively few actual applications. One of the main reasons is that for complex building components, modeling is difficult, the cost of BIM modeling design is very high, the efficiency is low, and it is difficult to meet the needs of the project.

[0004] At present, the conventional BIM model design method is to first establish a building component model family library, and then build various building component models and place them in the design position according to project requirements. For conventional building beam and column models, this method is quite efficient due to the relatively simple structure. However, for complex building components, it is very difficult to establish a component family library, and it is often not easy to locate and place them in the design position, which greatly limits the application of BIM design in these fields.

[0051] Step S2: Calculate the basic parameters of the vertical spacing a, horizontal spacing b, and vertical step h of the rack uprights based on the load above the rack, and establish a cube or triangular prism in space constructed according to the vertical spacing a, horizontal spacing b, and vertical step h as the basic spatial unit;

[0052] Here, a Boolean intersection operation is performed on the lower surface of the special-shaped curved concrete structure and the spatial basic unit, and three types of spatial basic units are obtained: (1) spatial basic units that are higher than the lower surface of the special-shaped curved concrete structure or exceed the projection range of the lower surface of the special-shaped curved concrete structure; (2) spatial basic units that intersect with the lower surface of the special-shaped curved concrete structure; (3) spatial basic units that are completely located within the projection range below the lower surface of the special-shaped curved concrete structure;

[0053] Step S3: Use the Geometry.Translate node to stack and fill the basic spatial units within the erection range V1 of the spatial formwork to obtain a simplified model unit block aggregate of the bent;

[0054] Here, the lower surface of the special-shaped curved concrete structure can be extracted, and the space between the lower surface of the special-shaped curved concrete structure and the ground can be stacked and filled using basic spatial units;

[0055] Preferably, the simplified model unit block assembly of the bent includes: the position and length of each member of the bent, which can quickly extract parameters to provide a material list for on-site construction;

[0056] Step S4, based on the erection range body V1 of the spatial formwork and the simplified model unit block aggregate of the bent, select Solid.DifferenceALL to perform Boolean operation to obtain the keel parameter body V2;

[0057] Here, a Boolean difference operation can be performed on the lower surface of the special-shaped curved concrete structure and the basic spatial unit completely located within the projection range below the lower surface of the special-shaped curved concrete structure to obtain the parameter block V2 of the keel formwork;

[0058] Step S5: Based on the formwork keel spacing D-JJ requirement, generate points P-LG-Y along the Y direction determined by the axis grid. Each P-LG-Y point generates a line LineY parallel to the X direction. Based on the points P-LG-Y, use ReferencePlane.ByLine to generate reference planes Plane-cut-Y for dividing the keel parameter block.

[0059] Here, the keel erection spacing D-JJ and the keel plate processing and segmentation spacing D-JG can be obtained according to the keel processing parameters;

[0060] Step S6: Use the Geometry.Intersect node to cut the keel parameter block V2 into keel planes Surf-LG with uniform spacing along each reference plane Plane-cut-Y.

[0061] Step S7: Select the Surface.Thicken node and generate a keel parameter block V-LG from each keel plane Surf-LG according to the keel material thickness D;

[0062] Step S8: Based on the keel processing segmentation spacing D-JG, points P-LG-X are generated along the X direction determined by the axis grid. Lines LineX are generated parallel to the Y direction at each P-LG-X point. Based on the points P-LG-X and using the ReferencePlane.ByLine function, reference planes Plane-cut-X for segmenting the keel parameter block V-LG are generated.

[0063] Step S9: Use the Geometry.Split node to split each keel parameter block V-LG along each plane Plane-cut-X into each keel processing unit block V-LG-DY that meets the processing spacing requirements.

[0064] Step S10: Select the Spring.FamilyInstance.ByGeometry node and the ExportToSAT node to convert each keel processing unit block V-LG-DY into a hyperbolic concrete shell structure formwork keel model.

[0065] For cast-in-place special-shaped curved concrete structures, construction requires a temporary formwork rack system with a standard height and accurate formwork. Before the formwork is fabricated, a rack system must be designed to meet the construction load requirements, facilitate on-site erection, and meet the requirements for formwork fabrication.

The BIM modeling method of the present invention standardizes and automates the design and modeling of formwork keels for hyperbolic thin-shell concrete structures. It is simple and easy to use, and can rapidly design formwork keels and conduct BIM modeling for different curved surface structures.

[0067] The simplified model of the shelving system presented in this invention includes the locations and lengths of each member, enabling rapid parameter extraction to provide a bill of materials for on-site construction. Through model substitution parameter conversion, the simplified shelving model can be converted into a high-precision BIM model, meeting diverse construction requirements, including lightweight models, BIM visualization, and high-precision 3D models.
