Definitions
- This invention relates to the construction of a tank for storing low temperature liquids.
- Low temperature storage is defined as storage at a temperature of +32 F. or lower.
- This invention is more particularly concerned with an insulating foundation system for storage tanks in low temperature service.
- Light aggregate insulating concrete on the other hand, while being of somewhat lower cost, presents other problems. Excessive heat of hydration can possibly be created by monolithicly placing a large mass of such insulating concrete. In addition, a large mass of such concrete may not have dried sufiiciently within a reasonable time after placement. Care must be taken to avoid excessive Water in mixing insulating concrete since the light Weight particles may be floated thus creating voids which could break down under load from the tank contents.
- the inner tank which is disposed in spaced relation to the outer tank is supported by a plurality of spaced hollow modules having loose fill insulation disposed therebetween and also therewithin.
- the loose fill insulation which may be expanded perlite or mineral wool and the like, is inexpensive, and the modules are formed of a pluarlity of interconnected wooden mem- 'bers or timbers.
- Means in the formof planking which comprises a plurality of wooden members is employed for interconnecting the modules with one another to unitize and rigidize the support means for the inner tank. This arrangement is unique and has not been employed in the prior art.
- the bottom insulating system described herein has many advantages over prior state of the art.
- the timber used for both the shell support modules and the bottom support modules has a greater compressive strength than light aggregate concrete, therefore the amount of materials may be reduced accordingly.
- the ultimate strength of the timber is higher at low temperatures than at atmospheric temperatures. Since this oven dry state (for insulating concrete) is impractical to attain or maintain, the timber used as structural support has a distinct advantage in that it reduces the amount of heat conducted into the tank.
- the timber used for the shell support modules and the bottom modules is also less expensive than an qeuivalent amount of light aggregate insulating concrete to carry the same load. Since the height of the bottom supoprt modules may be accurately controlled 'by sawing ofi the timber to the proper length, the use of unfinished lumber is possible.
- Both the shell support modules and the bottom support modules may be constructed with ease by the use of unskilled personal. This feature permits these components to be assembled anywhere. Since the components in the particular system described herein may be assembled at any construction site, the shipping problems are reduced accordingly. Since the amount of structural support can be reduced by using the timber (when compared to the amount of lightweight aggregate insulating units), the amount of loose fill insulation may he proportionately increased. This further achieves better over-all economy since the thermal conductivity of this loose fill material is better than either timber or lightweight aggregate insulating concrete, and the price of this loose fill insulation material is considerably less than either timer or the lightweight aggregate insulating concrete.
- the foundation of the present invention may be employed with tanks of any diameter with relative ease by simply varying the amount and spacing of the various components.
- the timber making up the shell support modules and the bottom support modules and the bottom planking may be treated to make it both fire retardant and decay resistant. Since the timber units are much stronger than lightweight aggregate insulating concrete units, they may be easily handled without the chipping and breakage problems associated with lightweight insulating concrete. This precludes the possibility of having lightweight insulating concrete units installed as a support system containing hidden cracks which could 'break down under the load imposed by the tank contents.

- FIG. 2 is a view on an enlarged scale taken substantially along line 2-2 of FIG. 1 looking in the direction of the arrows, and being broken away for the sake of clarity;
- FIG. 3 is an enlarged sectional view of a portion of the structure illustrated in FIG. 1;
- FIG. 4 is a top perspective view partly broken away illustrating the arrangement of the modules and planking for supporting the inner tank;
- FIG. 5 is a sectional view taken substantially along line 55 of FIG. 3 looking in the direction of the arrows;
- FIG. 6 is a sectional view taken substantially along line 66 of FIG. 4 looking in the direction of the arrows.
- a low temperature storage tank is indicated generally by reference numeral 10 in FIG. 1, the tank being supported above the ground level indicated by reference numeral 12 by a plurality of piles 14 extending upwardly from the ground. These piles may be supported by friction from contact with the earth and/ or by end bearing on suitable soil strata (not shown) disposed at a suitable distance below the ground level.
- a support means in the form of a supporting pile cap foundation 16 is provided formed of concrete or similar material having the necessary strength for supporting the weight of the tank.
- the storage tank includes an outer tank and an inner tank, the outer tank comprising a bottom wall 20 which is substantially flat, a substantially cylindrical side wall 22 extending upwardly from the bottom wall, and a top wall 24 closing off the upper end of the outer tank, this top wall being generally dome-shaped in configuration as seen in FIG. 1.
- the walls of the tank are formed of a suitable structural material such as steel or the like adapted to withstand the pressures applied thereto during .use in the tank, the walls being suitably secured to one another as by welding or the like.
- the inner tank of the storage tank includes a bottom Wall disposed substantially parallel with the bottom wall 20 of the outer tank, the inner tank also including a substantially cylindrical side wall 32 disposed inwardly of the side wall 22 to define an annular space therebetween.
- the inner tank also includes a top wall (not shown) which is also generally. of dome-shaped configuration and spaced from the top wall 24 of the outer tank.
- the space between the side walls of the two tanks as well as the space between the top walls thereof is filled with a loose fill insulation indicated generally by reference numeral 36 as is conventionally employed in low temperature storage tanks.
- This loose fill insulation may comprise in a typical example a granular material such as expanded perlite or a fibrous insulating material such as mineral wool and the like. Any suitable loose fill insulation may be employed for this purpose.
- the inner tank is supported in the position illustrated by a plurality of modules, and as seen most clearly in FIG. 2, a first plurality of spaced shell support modules are indicated generally by reference numeral 40, these shell support modules being disposed in an annular spaced array so as to be disposed substantially beneath the side wall 32 of the inner tank.
- each of these shell support modules comprises a 4- plurality of interconnected timbers or wooden members. While a specific arrangement of timers is illustrated, it will be readily recognized that each of the shell support modules may be built up as desired utilizing a plurality of timbers to afford the desired size and strength.
- each of the shell support modules 40 includes a first plurality of timbers or blocks 42 disposed in edge-to-edge relationship with one another and extending substantially radially of the storage tank.
- a second plurality of timbers or blocks 44 are supported on the upper surface of the timbers 42, timbers 44 also being disposed in edge-to-edge relationship with one another and extending substantially tangentially with respect to the storage tank.
- Each of the shell support modules also includes a third layer of timbers or block 46 disposed in edge-to-edge relationship with one another and supported on timbers 44, the timbers 46 being disposed substant ally parallel with the timbers or block 42. All of these various timbers 42, 44 and 46 are suitably fastened together by means of fasteners 48 extending through the timbers. These fasteners are illustrated comprising elongated nalls, although it should be understood that any suitable fastener means such as bolts or the like may be employed for rigidly securing the timbers together to provide an integrated module.
- Each of the modules also includes a wooden timber or flat member 50 secured to the upper surface thereof by a plurality of fasteners such as nails 52, it being noted that the edge 54 of member 50 as seen in FIG. 4 terminates short of the inner edge of the remainder of the module to define a radially inwardly positioned shoulder 56, these inner shoulders on the various modules serving to support the planking hereinafter described.
- a thin concrete levellng base 58 is cast over the bottom Wall 20 of the outer tank and comprises a leveling pad so as to provide a level foundation for the various support modules.
- the shell support modules as well as the bottom support modules hereinafter described are supported on the upper surface of this leveling pad so that the inner tank will be properly supported in position.
- the leveling pad may be formed of regular concrete approximately 6 inches in thickness.
- adjacent shell support modules 40 are disposed with respect to one another such that the facing ends 4% thereof are spaced apart to define a wedge-shaped space therebetween.
- a body of Fiberglas or similar material 60 is stiffed or forced into this space so as to be positioned in the location illustrated in FIG. 5 so as to retain loose fill insulation 62 inwardly thereof, this loose fill insulation as described hereinafter completely filling the space between the various bottom support modules of the foundation.
- This insulation is also disposed within the hollow modules.
- the bodies of Fiberglas 60 extend vertically between the leveling pad 20 upon which the shell support modules are supported to the undersurface of the bottom wall 30 of the inner tank which rests upon the upper surface of members 50 of the shell support modules.
- a plurality of shell anchor straps (or anchor bolts) 66 are provided, the upper ends of these straps being suitably secured as by welding to the outer surface of the side wall 32 of the inner tank, the shell straps extending down between adjacent spacing shell support modules as seen in FIG. 5, the anchor straps continuing downwardly and having the lower offset ends 68 thereof embedded within the material of the pile cap foundation 16 as seen most clearly for example in FIGS. 1 and 3. It is apparent that the relationship of the anchor straps and the bodies of Fiberglas material as seen in FIG. 5 are such that the anchor straps will tend ot hold the Fiberglas bodies 60 in operative position when subjected to pressure from the inner side thereof by the loose fill insulation bearing thereagainst.
- the use of anchor bolts in lieu of anchor straps will provide adjustment to compensate for differential contraction of the shell and anchor during cooldown.
- bottom support modules 70 As seen most clearly in FIG. 2, a plurality of bottom support modules indicated generally by reference numeral 70 are provided. A large number of these modules are provided in substantially equally spaced relationship beneath the bottom wall of the inner tank. The size and spacing of these bottom support modules will of course vary in accordance with the size of the tank and the load to be supported. Although only certain ones of the bottom support modules 70 are illustrated in FIG. 2, it should be understood that they will be disposed throughout the area beneath the bottom wall of the inner tank in substantially equally spaced relationship.
- each of the bottom support modules 70 is formed of four substantially identical rectangularly shaped timbers or planks 72, 74, 76 and 78 which are interconnected in the manner shown by suitable fasteners 80 comprising spikes, bolts, nails and the like to form hollow post-like sections. It is apparent that the bottom support modules each comprise a hollow construction adapted to receive loose fill therewithin.
- Means for interconnecting the modules with one another comprises planking, this planking including a plurality of adjacent timbers 90 disposed in edge-to-edge relationship as seen most clearly for example in FIGS. 3 and 4, these timbers being suitably secured to the respective modules by means of suitable fasteners such as spikes, bolts, nails and the like 92.
- the outer peripheral edge portion of the over-all planking is supported on the radially inner shoulders 56 of the shell support modules previously described, while the joints between the various lengths of planking aligned with one another are designed to be disposed over one of the bottom support modules.
- the individual members 90 of the planking are supported on the upper ends of the bottom support modules.
- the loose fill insulation 62 previously described is adapted to substantially fill the space between the bottom support modules 70 as well as the space within the hollow interiors thereof, this loose fill insulation extending between the bottom wall 20 of the outer tank and the undersurface of the planking, and also extending between adjacent sheel support modules as previously described in connection with FIG. 5 of the drawings.
