Description

Technical Field

[0001] This utility model relates to a bamboo-wound pipe concrete beam-column composite joint. Background Technology

[0002] Compared to traditional cast-in-place construction, prefabricated modular construction reduces on-site wet work, speeds up construction, requires less labor, and offers reliable product quality. It effectively improves production efficiency, shortens construction time, and reduces pollution and noise. Currently, building beam-column joints are mainly fabricated through on-site casting and prefabrication. On-site casting has drawbacks such as complex on-site formwork and rebar tying processes, high labor costs, and long construction periods. Prefabrication offers various forms of connection, high production efficiency, and short construction periods, but it also presents challenges related to the integrity and load-bearing capacity of prefabricated structural joints.
