Abstract
A tornado shelter has a dome-shape, sheltering wall formed by a multiplicity of modular, hollow/cavitied wall panel units manually assembled together at respective peripheral edges by the mating engagement of interlocking, male and female portions. Each wall panel unit is a one-piece molding with opposed side wall portions in spaced apart, parallel relation defining between them respective containers with filler openings adjacent a top and containing a filler material of alternately water, a rheopectic fluid, gel or granular particles, thereby increasing impact strength and anchoring weight. Selected base panel units are formed with respective eyes receiving ground anchoring stakes. Panel portions can be laminates reinforced by wire mesh or KEVLAR integrally molded therein.
