United States Patent 3,268,410 RADIATION SHELTER Edward I. Hayes, Livonia, and William E. Rumbles, Belleville, Mich., assignors to Kelsey-Hayes Company, Romulus, Mich., a corporation of Delaware Filed Sept. 22, 1961, Ser. No. 140,117 2 Claims. (Cl. 109-1) This invention relates to radiation shelters and more particularly to a prefabricated radiation shelter adapted for individual home installation.

It is an object of the present invention to provide a radiation shelter which is effective to shield its occupants from the harmful effects of a relatively high degree of radiation present in the surrounding atmosphere.

It is another object of the present invention to provide a radiation shelter which may be fabricated on a high production basis, sold in a disassembled and relatively compact package and thereafter conveniently assembled by a person of limited mechanical ability or construction experience.

It is a further object of the present invention to provide a radiation shelter which permits the use of sand, gravel, water or other inexpensive, readily available materials as theradiation absorbing or insulating component of the shelter.

It is a still further object of the present invention to provide a radiation shelter which possesses sufficient structural strength to protect the occupants of the shelter from falling debris and damage from physical impact of at least a limited degree.

It is still another object of the present invention to provide a radiation shelter which utilizes standard panels and wall sections whereby radiation shelters of varying sizes and shapes may be constructed from the same basic components.

It is still another object of the present invention to provide a radiation shelter of maximum structural strength for the quantity of materials utilized.

These and other objects of the present invention will become apparent" from the following detailed description taken in conjunction with the accompanying drawings wherein:

FIGURE 1 is an exploded perspective view of a radiation shelter constructed in accordance with the principles of the present invention;

FIG. 2 is an enlarged sectional view of the structure illustrated in FIGURE 1, taken along the line 2-2 thereof;

FIG. 3 is an enlarged broken sectional view of the structure illustrated in FIGURE 1, taken along the line 3-3 thereof;

FIG. 4 is an enlarged sectional view of the structure illustrated in FIGURE 1, taken along the line 4-4 thereof;

FIG. 5 is an enlarged broken sectional View of the structure illustrated in FIGURE 1, taken along the line 5-5 thereof;

FIG. 6 is an enlarged sectional view of the structure illustrated in FIG. 3, taken along the line 6-6 thereof, and

FIG. 7 is an enlarged sectional view of the structure illustrated in FIGURE 1, taken along the line 7-7 thereof.

Referring now to the drawings, a radiation shelter constructed in accordance with the teachings of the present invention is illustrated in FIGURE 1 as being located in the basement of a home having a basement floor 1t) and two adjacent perpendicular vertical exterior walls 12 and 14. Although not shown in the drawings, soil or earth is, of course, located on the outer sides of the walls 12 and 14. The prefabricated portion of the shelter is open on one side, which side is set against the wall 14 and utilizes the wall 14 as the fourth wall of the shelter. The shelter includes additional enclosing

side walls

16, 18 and 20. A roof structure 22 is supported on the side walls '16, 18 and 20 and encloses the shelter on the top, While the basement floor 10 encloses the shelter at the bottom. The side wall 20 will be seen as being parallel to the basement wall 12 and spaced several feet therefrom forming a passageway to provide access to a doorway opening 23 in the wall 20 adjacent the basement wall 14, through which access and egress to and from the shelter may be had.

While the so-called fallout of an atomic explosion consists of particles which may be carried with the wind or other fluid medium, the radiation or rays emanating from radioactive particles will only travel in a straight line. The design of the radiation shelter of the present invention is accordingly intended to place a large mass of radiation absorbing material in a direct line between the occupants of the shelter and any surrounding environment in which radioactive particles. or fallout may be expected to be found. This mass of material is sufficient to absorb radiation of a relatively high level which might result from the detonation of a nuclear device. It is, therefore, possible to leave the doorway opening 23 unclosed without danger of radiation traveling in a U-shaped path to enter through the doorway 23 and reach the occupants of the shelter.

As indicated in FIG. 2, each of the

walls

16, 18 and 20 is constructed of spaced inner and outer wall portions 24 and 26, respectively, of rigid sheet metal, which are adapted to hold and confine a loose or fluid radiation absorbing material placed in the cavity therebetween. Both of the wall portions 24 and 26 are constructed with the use of standard Wall panels 28 which are successively joined together at their adjacent complementary configured edges. While slightly dilferently shaped panels are utilized at the ends and corners of the

walls

16, 18 and 20, the greater portion of the length of each of said walls is made from the standard panels 28 and the walls may be built to any desired length by simply adding on additional standard panels. The construction of the standard panels is indicated in somewhat greater detail in FIGS. 3 and 5, where it will be seen that each of said panels includes a rectangular sheet metal member 30 having a plurality of vertically spaced, horizontally extending ribs 32 of V-shaped cross section. A vertically extending sheet metal strip 34 is welded to the sheet 30 along one side margin thereof and is provided with an inwardly extending flange portion 36 disposed perpen dicularly to the plane of the panel. The flange 36 has a perpendicularly extending shoulder portion 38 at its free edge which is bent parallel to the plane of the panel and extends toward the opposite side of the panel. Another vertically extending strip 40 is welded to the sheet 30 along the side thereof opposite from the strip 34 and is provided with an inwardly extending flange 42 arranged perpendicularly to the plane of the panel. A shoulder portion 44 is formed on the free edge of the flange 42 and extends parallel to the plane of the panel and in the same direction as the shoulder portion 38 of the strip 34. A column or vertical supporting member in the form of an angle iron 46 having two perpendicular flange portions 48 and 50 is integrally formed on the panel by having the flange portion 50 thereof welded to the inside of the flange 36, with the flange portion 48 disposed in engagement with the ribs 32.

Since the adjacent side portions of two adjoining panels are of a complementary configuration, it will be seen that when one panel 28 is placed adjacent another panel 28, the flange 42 of one panel will receive the flange 36 of the next adjacent panel with the shoulder portions 38 and 44 lying flatly against one another. Thus, any number of panels 28 may be connected successively together, so as to have their flanges 36 and 42 interfit. The panels 28 of the inner and outer walls 24 and 26 are disposed in opposite relation so that the interfitting panel flanges of one wall 24 or 26 will align with the abutting panel flanges of the other of said walls. By this means, web members 52 may be positioned flatly against the flanges 42 on the sides thereof opposite from the sides in engagement with the flanges 36. When so positioned, flanges 54 formed on opposite sides of the web members 52 will engage the ribs 32. The web members 52, the flanges 36 and 42 and the angle irons 46 all have aligned apertures in vertically spaced locations thereon that permit the application of bolts 56 and nuts 58 to hold the same in assembled relationship. Thus, the webbing 52 holds the inner and outer walls 24 and 26, respectively, in properly spaced relationship and divides the

walls

16, 18 and into successive units or compartments defined by a pair of opposite panels and a pair of successive web members 52. Each of said compartments is adapted to be filled with a radiation absorbing material which may consist of sand, gravel, water or other granular solids, fluids, or aggregate. If it is desired to utilize a fluid, said fluid is preferably enclosed within a flexible bag, as, for example, a plastic bag, which prevents leakage of the liquid out of the wall structure.

As previously mentioned, the standard panels 28 are not utilized at the ends and corners of the

walls

16, 18 and 20. As indicated in FIG. 2, the panel structure at one corner includes a panel member 60 having a main panel portion 62 forming a part of the inner wall portion 24 of the wall 18 and provided with a perpendicularly bent portion 64 forming a part of the inner wall portion 24 of the wall 16. The panel portion 62 is provided with an opening fitted with a bent conduit 66 connected successively to an elbow conduit 68 and a conduit 70. The conduit 70 registers with an opening formed in a panel member 72 forming a portion of the outside wall 26 of the wall structure 16. The opening in the member 72 may be conveniently covered with a louvered grill or the like, as indicated at 73. The panel member 72 has a perpendicularly bent portion 72a which forms a part of the outside wall portion 26 of the wall 18 and is connected to a panel member 74 by flange structure 75 of a similar construction to the flange structure previously described in connection with the standard panels 28. The

conduits

66, 68 and 70 cooperate to provide an air vent duct through which ventilating air may be brought into the interior of the shelter. When sand or other insulating material is introduced between the panels 60 and the panels 72 and 74, it will surround the

conduits

66, 68 and 70 and the angular shape of the duct formed by the

conduits

66, 68 and 70 eliminates the possibility of radiation entering the shelter in this location.

All of the side walls of the shelter, including each of the

side walls

16, 18 and 20, rest upon a base or floor channel member 76 which is of U-shaped cross section. The channel member is provided with a flat base having upstanding flange portions 77 on opposite sides thereof which are fastened to the inner and outer wall portions 24 and 26 by fasteners 77a, thereby enclosing the side walls at the bottoms thereof. The tops of the side walls are enclosed by an upper capping channel 78 of U-shaped cross section and having depending flange portions 79 connected to the inner and outer wall portions 24 and 26 by fasteners 79a. As may be noted in FIGURE 1, that portion of the upper capping channel 78 which is disposed over the doorway opening 23 is supported by an upright support 84.

For the purpose of facilitating the erection of shelving or other supporting members within the interior of the shelter, the upper capping channel 78 and the floor chanat. nel 76 are provided with U-shaped brackets 80 and 82, respectively, on the

inner flanges

77 and 79 thereof. By this means, a wooden post or support may be positioned against the inner wall portion 24 so as to be held at its upper ends by the brackets 80 and 82, such a post being indicated in broken lines at 83 in FIG. 3. Shelving, bunk beds or other structure within the shelter may then be fastened to such posts, in accordance with the desires of individual shelter owners.

The roof structure 22 rests directly on the upper capping channel 78 and includes a plurality of interlocked standard roof troughs 86. Each trough 86 has a bottom wall 88 provided with a vertical wall 90 on one side thereof with an inturned horizontal flange 92 being formed at the upper end of the vertical panel 90. A shoulder portion 94 depends from the free end of the flange 92. A reinforcing member in the form of an angle iron 96 is welded to the upright wall 90 at its upper corner so as to engage the flange portion 92. An upright wall 98 is formed on the opposite side of the bottom wall 88 and is provided with an outwardly extending horizontal flange 100 adapted to overlie and engage the flange portion 92 of the next adjacent trough 86. The flange 100 also has a depending shoulder portion 102 similarly engaging the shoulder portion 94 of the next adjacent trough member 86. Thus, the wall 90 of one trough 86 is held between the wall 98 and the shoulder portion 102 of the next trough 86.

A plurality of beam members 104 of T-shaped cross section are suspended between the

side walls

16 and 20 and extend parallel to the side wall 18 at evenly spaced locations between the side wall 18 and the basement wall 14. The beams 104 include an upstanding rib portion 106 and laterally extending shoulder portions 108. The bottom wall 88 of the trough members 86 is provided with a raised portion 110 on one side thereof which will rest directly on the adjacent of the shoulder portions 108, while the bottom wall 88 rests directly on the capping channel 78. A short vertical wall 112 connects the raised portion 110 to the bottom wall 88. The trough members 86 are similarly bent to provide a raised shoulder portion 114 resting on a rib 106 of the beam 104 on the other side thereof. The shoulder portion 114 is connected to the bottom wall 88 by a vertical wall 116 extending along the rib 106, a shoulder portion 118 resting on a beam shoulder 108 and a vertical wall 120 extending down the side of the shoulder portion 108. It will thus be seen that each beam serves to support two interlocked troughs 86. In view of the support afforded by the iron supporting beams 104 and reinforcing members 96, the troughs 86 may be made from relatively thin sheet metal, yet they will be held against excessive deflection or bending under the weight of a load of sand or other radiation absorbing material placed within the troughs.

The troughs at the ends of the roof structure are of a slightly modified construction, as indicated at 124. The trough 124 has a straight outer side wall 126, which provides a smooth appearance substantially coplanar with the outer side wall 26 of the roof structure 22. A trough 128 is positioned at the end of the roof structure 22 adjacent the basement wall 14 and is provided with an upstanding wall 130 engaging the basement wall 14 and having an inturned flange portion 132 which is reinforced by an angle iron 134. The corner structure of the trough 128 at the lower portion of the upstanding side wall 130 is conformed to and rests upon an angle iron 136 which is supported between the

wall structures

16 and 20 parallel to the T-beams 104. As indicated in FIG. 1, the trough 128 and the adjacent of the troughs 86 extend beyond the side wall structure 20 and are supported by horizontal brace members 144 connected to the wall structure 20 and are additionally supported by upright support members 146 to provide insulating material over the space immediately in front of the doorway opening 23. This further prevents possible entrance of radiation into the shelter through the doorway opening 23.

Varying insulating materials may be positioned both within the side wall structure and within the troughs of the roof structure 22. As indicated in FIG. 3, the side walls may be filled with sand 148. As also indicated in FIG. 3, one of the troughs 86 may be interiorly sprayed with a plastic or other water-impervious lining 150 and the trough thereafter filled with water 152. As indicated in FIG. 4, one of the troughs may be filled with a flexible bag 154, which is filled with water 156.

As shown in FIG. 7, the ends of the

troughs

86, 124 and 128 are closed by end closure panels 138 having an upper flange 140 which may be fastened to the tops of the troughs. In addition, the panels 138 are fastened at the bottoms thereof to flanges 122 extending upwardly from the bottoms of the troughs.

From the foregoing, it will be appreciated that the entire shelter, except for the radiation absorbing material utilized, may be fabricated in a factory under high production methods. The various troughs, wall panels and other components may then be sold in a disassembled package. A home owner purchasing such a package may readily assemble the shelter in his basement with a minimum number of tools, as, for example, simple extension wrenches. It may also be necessary for the home owner to level off the floor with cement, if the floor is excessively warped or uneven or to secure the floor channel 76 and the

side walls

16 and 20 to the floor and the basement walls 12 and 14, respectively, by means of anchor bolts. After assembly of the side walls, the space between the inner and outer walls 24 and 26 is filled with sand or other insulating material, and thereafter the roof structure 22 is installed in place. Finally, the radiation absorbing material is placed into the troughs of the roof structure. For convenience in inserting sand in the troughs of the roof structure, corrugated cardboard boxes may be obtained of a width and height corresponding to the dimensions of the trough. These boxes may then be filled with sand and slid down the lengths of the troughs until each trough is filled with sand. When using Water as an insulating material, it is possible to provide outlet spouts such as indicated at 158 in FIG. 4 for the purpose of providing drinking water for the occupants of the shelter.

It will be seen that the individual panels of the side walls of the present shelter are horizontally ribbed to provide strengthening against outward bowing under the weight of the material placed in the side walls. The sheets 30 may be fed through high production machinery to accomplish the bending and rib forming operation and the

strip members

34 and 40 subsequently welded to the sheets 30. The flanges which are formed on said rib members provide a convenient means of fastening the panels together and the shoulder portions on said flanges, which overlap, help prevent the escape of material out of the wall structure. The web members 52, which interconnect the inner and outer walls 24 and 26, divide each of the

walls

16, 18 and 20 into separate compartments, so that any leakage developing in one unit will not alfect the other compartments. Furthermore, the web members increase the overall rigidity and strength of the wall structure, as well as facilitating the erection or disassembly of the shelter on a unit by unit basis.

While it will be apparent that the preferred embodiment herein illustrated is well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope or fair meaning of the subjoined claims.
