Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing of building construction, and in particular to an intelligent arranging method of keels of a lightweight partition wall. Background Art

[0002] Lightweight steel keel partition walls are increasingly used in public building decoration projects. However, due to the differences in height, length, and openings of different walls, the keel layout is quite different, and they need to be further designed separately, which leads to a large workload for further design. The layout of the keel needs to consider issues such as maximum spacing, aesthetics (uniform spacing), opening reinforcement, and top reinforcement, making further design difficult. However, due to the limited time and experience of in-depth design engineers, there is often no time to optimize the design, resulting in problems such as the keel passing through the opening and the height difference of the keel connection requiring reinforcement, which increases the difficulty of construction and the cost of keel reinforcement. Summary of the invention
