Abstract

A method for forming a solidified granular material (), in which granules () are charged into a tubular frame member () and then heated together with the frame member, to solidify the granules. The granules include a mixture of first granules () and second granules (), each of which second granules has a thermoplastic resin shell enclosing a solid or liquid which expands by vaporization. The mixture is charged into the frame member and heated together with the frame member. The heating causes the second granules () to expand and the surfaces of the second granules to melt for bonding with the first granules (). The mixture, upon cooling, becomes a solidified granular material (), filling the frame member with no space therebetween.
