United States. Patent This invention relates to bomb and fall-out shelters and particularly to precast bomb shelters for individual family units or small groups which may be quickly and inexpensively set up and which afford the necessary protection against radioactivity fragmentation and heat which would be expected to attend an atomic explosion.
The need and desire for some satisfactory easily and inexpensively installed bomb shelter is known and recognized by all. The widespread death and destruction which might attend an atomic explosion in any area makes more significant the need for some form of protection for small family units, even in non-industrial and suburban areas which surround industrial centers. There have been several proposals for the construction of bomb shelters. They are, however, expensive to build and take considerable time for installation. For example, monolithic poured concrete shelters have been proposed as These shelters while being eflicient and serving the purpose are expensive to con- They require long curing times in order to attain the necessary strength and thus tie up equipment as well as forms and the like on the spot. Another form of cast situ shelter is represented by Lutteke Patent 2,729,966, which is subject to the same problems as the Rudinger patent. A precast bomb shelter has been proposed by Rudinger in Patent 2,822,765. This bomb shelter, however, is of such complex form as to be difficult to cast as well as difficult to assemble.
I have invented a fall-out and bomb shelter which is inexpensive to construct, which is precast and therefore eliminates the need for expensive casting operations on the spot and is made in segments which are simple to handle and assemble. The structure of the invention, when assembled, is strong and eliminates any possibility of gamma ray penetration.
I provide a precast masonry fall-out shelter having offset interfitting portions along all edges whereby to eliminate any straight-through passages between the sides and ends as well as the top and bottom. This structure provides great strength, with every member interlocked with every other member. Preferably I provide a precast masonryfloor member having step notches around all four edges, the side of said notches lying at an angle greater than 90 but less than 150 and an upstanding flange or tongue extending transversely across said member from one side to a point spaced from the opposite side, a pair of precast masonry end walls having step notches around all four edges, the sides of said notches lying at the same angle as the notches of the floor member, a pair of precast masonry side walls having step notches around all four sides and having the sides thereof at the same angle as the notches of the floor, a flange or tongue on one of said side walls extending transversely across the side and position to correspond with the flange or tongue on the floor member, an intermediate wall member adapted to slidably fit over and engage the flanges or tongues on the floor and sidewall and a top member having step notches'around all four edges adapted to interfit the notches of the end and side walls and a hatchway adjacent the intermediate wall. The parts are assembled and grouted at the joints to form a tight sealed unit in which the interfitting corners aid in supporting all parts of the assembly as a unitary whole.
In the foregoing general description I have set out certain purposes, objects and advantages of my invention.
Other objects, purposes and advantages of my invention will be apparent from a consideration of the following description and the accompanying drawings in which-- FIGURE 1 is an isometric view partly exploded and partly cut away of a bomb shelter according to my inventlon;
FIGURE 2 is a top plan view of a form for casting the walls of the shelter of FIGURE 1;
FIGURE 3 is a section on the line IIIIII of FIG- URE 2;
FIGURE 4 is a top plan view of a segment of mold for casting the floor of a shelter of this invention;
FIGURE 5 is a section on the line VV of FIG- URE 4;
FIGURE 6 is a top plan view of a segmentof mold for casting the roof of a shelter of this invention;
FIGURE 7 is a section on the line VIll-VII of FIG- URE 6;
FIGURE 8 is a top plan view of a mold for casting a blast wall for a shelter of this invention;
FIGURE 9 is a section on the line IX-IX of FIG URE 8; and
FIGURE 10 is an isometric view of a segment of the shelter of FIGURE 1 showing the indexing of the hatchway.
Referring to the drawings I have illustrated a bomb and fall-out shelter of the present invention. A floor It) is formed of precast reinforced concrete in mold 11 having a keyway 12 extending from one edge transversely across the surface to a point spaced from the opposite wall and a shoulder 13 extending around all four sides. The resulting cast floor has a flange or tongue 14 corresponding to keyway 12 and a notch 15 corresponding to shoulder 13 extending around its edges. The inner surface 16 of notch 15 is sloped so that the walls of the notch lie at an angle greater than to one another. This serves two purposes, case of release .from the mold and a grouting sealing area when assembled.
A roof 22 is formed of reinforced concrete by casting in a mold 23 having a keyway 24 corresponding to keyway 12 of the floor and shoulders 25 around all four sides, and a hatchway exit opening 2 2:: at one corner. The resulting cast roof has a flange or tongue 26 corresponding to keyway 24 and notches 27 corresponding to shoulders 25. These notches interfit with the corresponding notches of the end and side walls.
A blast wall 28 is formed of reinforced concrete cast in a mold 29 having an inner liner 30 carrying keyways 31. The resulting blast wall when removed from mold 29 carries with it inner mold liner 30 which is removed to leave keyways or grooves 32 along three sides of the blast wall.
The hatchway 33 is formed of precast reinforced concrete and is provided with projections 34 adapted to fit into corresponding openings 35 around the exit hatch opening 22a.
A doorway 36 may be optionally provided in the end wall adjacent the hatchway as indicated in chain line, if desired.
The shelter is assembled into a hole, previously dug, by lowering the floor 10 by means of lifting lugs 37 into place and thereafter placing the sidewalls 18 and cover.
' The device is ready for use as soon as assembled without any of the delays for curing or for forming building or the like which characterize cast in situ shelters. It is formed in simple, interfitting, readily installed parts which are readily stored in quantity and quickly assembled.
