Description

Technical Field

[0001] This invention relates to building construction, and in particular to a method for positioning inclined column bolts based on BIM technology. Background Technology

[0002] Columns are load-bearing components in building structures that withstand axial pressure, and are one of the most important load-bearing components in a building structure. Inclined columns transfer the weight of the building to the foundation through their diagonal support. Compared to traditional upright columns, inclined columns can more effectively distribute weight, reduce pressure on the column itself, and improve structural stability. Therefore, inclined columns are frequently seen in large stadiums.

[0003] When the inclined column is too high, it is usually constructed by using a combination of concrete inclined columns and steel structure inclined columns. In this case, it is necessary to pre-embed inclined column bolts in the concrete inclined column. However, the positioning of the pre-embedded inclined column bolts is a difficult problem in the construction process. The traditional construction method is to weld a positioning frame and tie the positioning frame and the steel reinforcement. This method usually cannot accurately position the inclined column bolts. Moreover, when the top of the concrete column is too high, the risk factor increases significantly, posing a great hidden danger to the safety and quality of the construction.
