Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing technology in building construction, and in particular to an intelligent arrangement method for the keel of a lightweight partition wall. Background Technology

[0002] Light steel keel partition walls are increasingly widely used in public building decoration projects. However, due to differences in height, length, and openings, the keel arrangement varies significantly between different walls, requiring detailed design for each, resulting in a large workload. The keel arrangement needs to consider issues such as maximum spacing, aesthetics (uniform spacing), opening reinforcement, and top reinforcement, making detailed design quite challenging. Furthermore, due to the limited time and experience of detailed design engineers, there is often no time for design optimization, leading to problems such as keels penetrating openings and keel connections with height differences requiring reinforcement, increasing construction difficulty and keel reinforcement costs. Summary of the Invention

[0093] S3.3, Determine the elevation of the bottom surface of the opening (ohd) j Is it equal to the elevation h of the bottom of the wall? l If the elevation of the bottom surface of the opening is ohd j Not equal to the wall bottom elevation h l Draw the keel at the bottom of the opening (the size of the keel drawn here is the same as the size of the keel drawn in step S3.2), and return to S3.1;

[0094] S3.4, Draw keels with a width of bw at both ends of the partition wall;

[0095] S3.5, Based on the existing keel on the partition wall W, set the wall between two adjacent keels on the partition wall as a sub-wall;
