Abstract
A shelter contains walls enframed by members of a metal structure. So that the shelter offers efficient protection against violent explosions, and especially against the blast produced by a nuclear explosion, a wall consists of an internal panel having at least one metal side connected electrically to structure members enframing the wall, an external armoring panel, an air space between the internal and external panels, and energy absorbing means, such as flexible synthetic seals, located in the air space for keeping the external panel floating between the internal panel and flanges of the enframing members. This wall can form a door to the shelter.
Claims40
A shelter including walls, and a metal structure having members enframing said walls, at least one of said walls comprising:
- (a) an internal panel having at least one metal side secured to and electrically connected with said structure members enframing said wall;
- (b) an internal shielding panel having an outer surface the peripheral edge portions of which face the inner surfaces of outer flange portions of said wall structure members, respectively;
- (c) an air space extending between said internal and external panels and said structure members, respectively;
- and
- (d) first energy absorbing means arranged in said air space for applying said peripheral edges of said external panel against the inner surfaces of said outer flange portions, thereby keeping said external panel floating between said internal panel and said structure member outer flange portions.
A shelter comprising walls and metal structure members enframing said walls, respectively, respective structure members that enframe a wall each having an inner flange and an outer flange arranged parallel with said wall, at least one of said walls comprising:
- (a) an internal panel having inner and outer metal sides, said outer metal side being fastened and electrically connected with an inner side of said inner flanges of said respective members;
- (b) an external shielding panel having peripheral edges of an outer side facing an inner side of said outer flanges of said respective members, said panels being spaced to define an air space extending between said outer side of said internal panel, an inner side of said external panel and lateral sides of said respective members;
- and
- (c) first energy absorbing means lodged in said air space and in resilient contact with an outer side of said inner flanges of said respective members and with said inner side of said external panel for applying outer side peripheral edges of said external panel against said inner side of said outer flanges, thereby keeping said internal panel floating between said internal panel and said outer flanges.
A shelter comprising walls, metal structure members enframing said walls, and a door, said door including a fillister frame formed by some of said structure members, and a leaf hinged to said fillister frame, said leaf comprising:
- (a) a back-fillister frame hinged to said fillister frame and formed by metal members substantially analogous to said structure members, each of said back-fillister frame members having an inner flange and an outer flange arranged parallel with the sides of said leaf;
- (b) an internal panel having inner and outer sides, said outer metal side being fastened and electrically connected to an inner side of said inner flanges;
- (c) an external shielding panel having an outer side the peripheral edge portions of which face an inner side of said outer flanges, said panels being spaced to define an air space extending between said outer side of said internal panel, an inner side of said external panel and lateral sides of said back-fillister frame members located between said inner and outer flanges;
- and
- (d) first energy absorbing means lodged in said air space and in spring contact with an outer side of said inner flanges and with said inner side of said external panel for applying outer side peripheral edges of said external panel against said inner side of said outer flanges, whereby said external panel is in floating relation between said internal panel and said outer flanges.
