Abstract
A support structure for supporting a foamable material in a cavity of a hollow structural member so that the foamable material blocks the cavity of the hollow structural member when it is foamed by external heating. The support structure includes a support member including a main body which has an external dimension smaller than the dimension of a transverse cross section of the cavity, a foamable material receiving wall provided on the main body, and a restriction flange extending from at least one of the main body and the foamable material receiving wall. The support member is disposed in the cavity in such a manner that the restriction flange is substantially perpendicular to the longitudinal direction of the cavity. The foamable material has a substantially annular configuration and is profiled substantially to conform to the configuration of the transverse cross section of the cavity. The foamable material is arranged along the foamable material receiving wall of the support member.
