CONCEALED CONNECTION STRUCTURE FOR PROFILED BEAMS AND COLUMNS

摘要

A concealed connection structure for profiled beams and columns comprises a profiled column (1), and a profiled beam (2) perpendicularly connected to the profiled column (1). An upper plug (3) and a lower plug (4) are pre-arranged in a T-shaped groove on one side of the profiled column (1). A retractable connection-locking mechanism is arranged in a cavity of the profiled beam (2); said retractable connection-locking mechanism extends into the T-shaped groove on the side of the profiled column (1) and fits to the upper plug (3) and the lower plug (4). The connection structure allows convenient assembly and disassembly, and features high rigidity and stability at the joint.
