Structure and method for closing and reinforcing hollow structural members

摘要

A structure for closing a cavity of a hollow structural member and for reinforcing the hollow structural member. The structure includes a reinforcement member comprising a plurality of reinforcement plates arranged in a spaced relationship. The reinforcement plates being interconnected to form at least one receiving space therebetween. The reinforcement member being disposed in the cavity in such a way that the reinforcement plates are substantially perpendicular to the longitudinal axis of the hollow structural member. At least one foamable member is received in the at least one receiving space of the reinforcement member. The foamable member being adapted to close the cavity and to secure the reinforcement member in the cavity when expanded by external heating.
