Abstract (en)
[origin: US4507899A] An underground protective shelter installation has several protective cells connected to one another, the cells being assembled of prefinished steel-reinforced concrete components which are hermetically sealed to one another and braced by clamping components. At least one opening is provided in a protective chamber for access to an inner chamber of the protective shelter installation. The protective chambers essentially comprise two basic prefinished components, namely a substantially circular disk used as an upper cover, intermediate ceiling, or as a lower closure, and a cylindrical ring, one story high and located between two of the disks. The entrance level includes an inner passageway and an outer entrance passageway having an exit opening above the protective shelter installation in the outdoor area.
