Description

TECHNICAL FIELD

[0001] The present application relates to a kind of based on component relative position relationship stiff node deepening design method and equipment. BACKGROUND

[0002] Stiff node is the important construction part of combination of fabricated concrete structure and steel structure, is widely used in high-rise building, industrial plant and other structural forms.Because of the composite of concrete, steel bar and section steel in its node area, the structure is complex, and the reinforcement is dense, the conventional two-dimensional design drawing is difficult to accurately express its spatial relationship, which brings great difficulty to construction.

[0003] In order to solve the problem of expression and construction difficulty of stiff node design, three-dimensional modeling software is generally used in the industry at present to carry out deepening design and modeling on the node.In three-dimensional modeling software, users can configure the relative relationship of section steel, beam, plate, steel bar and other components by manual modeling or calling existing plug-in tools.However, the existing method still has the following problems in practical application:

[0004] Low modeling efficiency and tedious manual operation: in the traditional way, users need to manually select components, set connection plate, steel bar and other construction parameters, and adjust the position relationship one by one.The operation process depends on the experience of designers, and the efficiency is low and easy to make mistakes.

[0005] Lack of standardization rule driven modeling mechanism: most of the current deepening plug-ins lack flexible rule definition and constraint function, cannot automatically adjust the geometric arrangement between components according to the specific position relationship of node (such as the absolute elevation of beam, relative offset, etc.), and are difficult to adapt to the needs of complex projects.

[0006] The problem of interference between components cannot be effectively solved: in the stiff node area, steel bar, section steel, connection plate and other components intersect frequently, and collision is easy to occur.The detection and processing ability of the current tool for interference between components is weak, which cannot automatically identify and handle component collision in the modeling stage, resulting in high modification cost in later period.

[0007] The drawing of connection plate lacks parameterized control: in the existing technology, the drawing of connection plate often depends on manual setting of plate thickness, position and other parameters, lacks unified parameter input interface, and cannot automatically adjust shape and installation angle according to the relative position of section steel and beam, which affects the design consistency and construction operability.

[0008] In summary, the deepening design method in the existing three-dimensional modeling software has defects in automation degree, rule driving ability, component coordination and user interaction friendliness, and it is difficult to meet the needs of rapid and accurate modeling of stiff nodes in complex structure projects. Therefore, a deepening design method based on rules and relative position relationship is needed to automatically generate connecting plates and consider component collision detection and layout optimization, so as to improve modeling efficiency, reduce design errors and enhance model constructability.

The application supports the user to input multiple beam information at a time, and the plug-in can automatically analyze the connecting plate generation logic according to the position of each beam relative to the steel, which is suitable for complex situations such as T-shaped nodes, cross nodes, and different high beam nodes commonly seen in actual engineering, greatly improving the design adaptability and universality.

[0084] 4. User-friendly interface, low learning cost

[0085] The plug-in interface adopts a partitioned parameter input design, which is clear in classification and intuitive in logic, and can complete the detailed design modeling without mastering complex three-dimensional operation procedures. In actual use feedback, the average learning time is less than 20 minutes to master the operation, which is convenient for popularization and application in engineering design units.

[0086] 5. Significant economic and social benefits

[0087] Due to the improved design efficiency, reduced design rework, and standardized node construction, the method can effectively compress the design cycle of the deepening stage before construction, indirectly save the design cost, and has obvious economic benefits.

Through the method, the modeling efficiency and accuracy of the stiff node in the three-dimensional modeling software environment can be significantly improved, the work burden of the designer is reduced, and more reliable and standardized three-dimensional model support is provided for subsequent construction drawing and construction implementation.

[0172] The stiff node deepening design method based on rules and relative position relationship provided by the application can realize the automatic drawing and optimized arrangement of the connecting plate in the profile steel node area through the plug-in secondary development on the three-dimensional modeling software, combined with the user input parameters, the spatial relationship of components and the construction rules, compared with the prior art, has the following significant technical effects:

[0173] 1. The modeling efficiency is significantly improved

[0174] Under the traditional method, the designer needs to manually establish the connecting plate between components one by one, and position, rotate and adjust the size through experience judgment, so the modeling efficiency is low and error is easy to occur. The automatic modeling and arrangement of the connecting plate can be completed within a few seconds after the user inputs the beam parameters through the preset parameterization logic and rule system of the method, and the efficiency is improved by more than 80%.

[0175] 2. The accuracy and standardization of the node construction are improved

[0176] The method can automatically analyze the construction type according to the actual spatial position relationship of the beam and the profile steel, such as whether the connecting plate needs to be set, which plane the connecting plate should be arranged in, and how thick the steel plate should be used, so that the problem of non-standard construction caused by manual judgment error is avoided, and the related requirements in the current national Concrete Structure Design Specification and Technical Specification for Fabricated Concrete Structures are met.

[0177] 3. The processing capacity of the multi-beam complex node is supported

[0178] The traditional plug-in can only process single-beam single-node, and is difficult to adapt to complex intersection nodes. The application supports the user to input multiple beam information at a time, and the plug-in can automatically analyze the connecting plate generation logic according to the position of each beam relative to the profile steel, and is suitable for complex conditions such as T-shaped node, cross node, different height beam node and the like in actual engineering, greatly improving the design adaptability and universality.

[0179] 4. The user interface is friendly, and the learning cost is low

[0180] The plug-in interface adopts a partition type parameter input design, is clear in classification, and is logical and intuitive, and without mastering complex three-dimensional operation procedures, deepening design modeling can be completed. In actual use feedback, an average learning time is less than 20 minutes, and skilled operation can be achieved, and application in engineering design units is facilitated.

[0181] 5. Economic and social benefits are remarkable

[0182] Due to the improved design efficiency, reduced design rework and standardized node structure, the method can effectively compress the design cycle of the deepening stage before construction, indirectly save the design cost, and has obvious economic benefits.
