Technical Field

The utility model relates to the technical field of engineering structures, in particular to a spliced and socket combined beam-column connecting node of a composite material member.

Background

The assembled fiber reinforced composite structure is a novel assembled structure assembled by fiber composite components, and in the structure, node connection modes such as full-fiber integrated forming connection, bolt connection, bonding connection and the like are generally adopted because the fiber reinforced composite components cannot be welded. For all-fiber integrated forming connection, the construction operation condition requirement is high, the connection forming process is complex, the construction efficiency is relatively low, and the economic cost is high; when the bolt connection mode is adopted, the components are required to be perforated, on one hand, local stress concentration at the edges of the holes is easy to cause, on the other hand, continuous fibers in the components are forced to be broken, so that the bearing capacity of the components is reduced, the structural integrity and reliability are affected, a relatively conservative safe redundancy design is required to be carried out during design, or reinforcing and reinforcing measures are considered to be adopted at the inner sides of the hole walls, and the comprehensive efficiency-cost ratio is not high; when single bonding connection is adopted, the influence of the durability of the structural adhesive on the service performance of the engineering structure node is required to be considered, and the economic cost is increased intangibly. The present utility model thus improves upon this by employing a composite component split and socket composite beam-to-column connection node that avoids direct tapping of the fiber reinforced composite component.
