Technical Field
The invention relates to the technical field of indoor structure design, in particular to a method and a device for automatically generating a constructional column based on a Revit platform.
Background
The constructional column is a reinforced concrete column which is used for improving the anti-seismic performance of a multi-layer building masonry structure, arranging a reinforced concrete column at a proper position in a masonry wall of a house, connecting the reinforced concrete column with a ring beam and jointly enhancing the stability of a building.
The structural column arrangement scheme is one of achievements of structural professional design, and means that a structural engineer expresses information such as a plane position, a section and the like of a structural column in a plane expression mode.
The current construction column arrangement method based on the Revit platform in the industry is as follows: in a Revit platform, a structural engineer generates a constructional column at a position meeting structural design rules (including national and industrial general design standards and time-substituted Chinese internal design standards and drawing rules) by judging the relationship between masonry walls, door and window openings and vertical concrete members (including but not limited to shear walls, structural columns, constructional columns and the like) based on a three-dimensional model.
The technical scheme has the defects that: 1. the manual drawing is easy to generate mistakes and omissions, and special manpower is needed for correction and modification; 2. the efficiency is low, the relationship between the masonry wall and the vertical concrete member needs to be judged manually, the length of the masonry wall is measured, and when the building plane is large, the number of constructional columns to be arranged is large, so that the time waste is caused; 3. for the same situation, different designers understand different national specifications, design standards and the like, the arranged constructional columns are not completely the same, the rules are not uniform, and the quality of the design result is influenced.
