These and other objects and advantages of this invention will hereinafter appear and for purposes of illustration, but not of limitation, an embodiment of the invention is shown in the accompanying drawings, in which- FIGURE 1 is a schematic elevational view partially in section of the insulated hold of a ship embodying the features of this invention;

Descriptionof the invention can best be made with reference to particular materials to be maintained under a predetermined set of conditions, but it will be understood that the inventive concepts can have application to other materials having an entirely difierent set of conditions for storage or transportation but wherein a common problem exists with respect to the need to insulate a large space in which a material which needs to be maintained at extremely low temperature is to be housed.
Thus, description will be made with reference to the problem of the transportation of large volumes of a natural gas which is liquefied at a source of plentiful supply for transportation by ship to an area where a deficiency exists and where the liquefied gas can be reconverted to a gaseous state for use. Transportation in a liquefied state is desirable because the same volume of gas can be carried in about ,4 of the space when reduced from a gaseous state to a liquefied state but, to maintain the liquefied gas in a liquefied state, it is necessary to hold the liquid at a temperature below its bubble point or its critical vaporization point. In the case of methane, comprising the major proportion of natural gas, this means that the liquid must be held at a temperature of about in practice, an inner hull 18 will be 7 terial characterized by 258 F. or less, depending upon the amount of heavier hydrocarbons in the gas when, as is desirable, the liquefied gas is housed in suitable containers or tanks at about atmosphericpressure. a
The storage tanks 10 will be of large dimension for housing a suitable quantity of the liquefied gas. Use may be made, for example, of tanks having a capacity of [from 1 to 20,000 barrels and which, when formed to rectangular shape, may have a width and length of from 3-90' feet and a height 7-4-00 feet. These tanks will be located in the hold space 12 of a ship 14. This raises a number of problems common even to land storage tanks. The steel hull 16 of the ship cannot be cooled to a temperature as low as the liquelfied natural gas without raising some very obvious and serious problems related to the strength of the metal and the build-up of ice on the portions of the hull having water in contact therewith. Thus, provided inclosely main hull 16 and the space 12 in which the spaced-apart relation to the outer inner hull will thus define the hold storage tanks 10 are located.
In order to minimize heat loss into the tanks, it is desirable to insulate the entire hold space, as distinguished from the individual tanks. The provision of an inner hull makes available a relatively flat and smooth inner surface 26 onto which the insulation 22 can be mounted. As a result, it has been determined that the coverage of the large surface area defining the hold space can most economically and most efiiciently be achieved by the prefabrication of large panels 24 of a built-up insulation, which panels can be mounted onto the walls defining the storage space to provide an insulation lining.
In my copending application Serial No. 646,001, filed March 14, 1957, of which this application is a continuation-in-rpart, and in my copending applications Serial No. 743,541, filed June 23', 1958, entitled Insulation Panels for Thermally Insulating a Storage Space, Serial No. 743,630, filed June 23, 1958, entitled Means and Method for Mounting Prefabricated Panels of Insulation, now Patent No. 3,026,577, and Serial No. 743,569, filed June 23, 1958, entitled Insulation Structure and Means for Manufacture, description is made of the insulation panels and their method of assembly to form the insulated space.
Briefly described, the panels are prefabricated into units of 4 X 8 feet or into units of 8 x 8 feet, or larger, and a thickness of about l0-20 inches. They are formed with inner and outer face plies 26 land 28, respectively, of a high stren th material, such as plywood, and with a relatively thick section 30 inbetween formed of a mamass integrity and low heat conductivity, as represented by a highly porous, low density wood such as balsa wood or quippo, or a honeycomb structure formed of paper, treated or coated paper, or thin Wooden plies.
The panels 24 are mounted onto the side walls 18 and on the floor by bolt and nut means wherein the bolts 32 fixed to the metal supporting wall extend inwardly through spaced-apart openings provided in theinsulation panels to enable insertion of a nut and washer assembly 34 which is brought into pressing engagement against the inner face of the plywood. panel 28 to secure the plywood facing and the integral panel to the wall. The openings '36 through which the assembly is achieved are subsequently plugged with insulating material to complete the panel. The panels are thus independently mounted on the wall in side-.by-side and end-toend relation substantially completely to cover the entire surface.
It will be apparent that, at the time that the insulation panels are installed, the ambient temperature may be somewhere within the range of 70-l00 F. When, howsirable for a number of reasons.
. r The blocking of the openings devolped "linear side walls of adjacent panels can be taken care ever, the tanks or tank mounted within the insulated I F. The wide temperature drop will result in considerable contraction in the outer portions of the insulation panels .such that a spaced relationship will develop therebetween in use. Such spacing between the panels in use is unde- In the first place, convection currents can flow through the space to minimize the effect of the insulation and to increase the heat loss to the material in the tanks. In thesecond place, the lack of a sealing relationship between the panels makes it possible for liquid escaping from the tanks or spilled in filling or the like, to flow outwardly into contact with the metal walls, with the resulting reduction in the temperature of the metal to dangerous levels. Many other objections could be enumerated.
Thus, it is desirable to provide a means for blocking the openings between the panels and to provide a fluidtight seal therebetween notwithstanding the changes in the dimensions of the openings as effected by the expansion and contraction movements taking place in the panels as the temperature falls and rises with introduction and removal, respectively, of the liquefied cargo.
between the of by the use of elongate slotted splines 38 fitted into contiguous grooves provided in the linear edge portions of adjacent panels and adhesively bonded along their side walls to the adjacent side wall portions of the panels. The slotted spline will enable deflection of the adjacent por=tions with the panels during expansion or contraction 4 of the linear expansion strips 49. The opening should be of a depth greater than the thickness of the plywood facing 24 but not so deep as to extend through the insulation layer 30. In practice, with a 4 x 8 or 4 x 16 panel or any other dimension inbetween, it is suiiicient if the diameter of the opening is from 6 to 18 inches and if it is formed to a depth of from 3 to 9 inches. If it were possible to route out a square section or a rectangular section, the opening 50 could be made square or of other shape with an equivalent portion of the opening lying in each of the panels. If the openings are provided by preforming the recesses in the panels in advance of their installation, it would be possible to make use of an opening of a different shape in cross-section.
' The opening 51 at the intersection is adapted to be plugged with a block 52 shaped to correspond to the cross-section of the opening for receipt therein in fitting relation. The block can be formed of a resilient material preferably having insulating characteristics and a mass while the base of the spline maintains its integrity to pro-.
vide the interconnection between the panel sections. This is more fully described in my copending application Serial :No. 743,539, filed June 23, 1958, Insulation Structure and Means for Manufacture.
' The sealing relation between the linear edges of the .adjacent panels is achieved by the use of an elongate expansion strip 40 formed of a fluid-impervious material :having -a central bulbous portion 42 which is loosely received in a groove 44 provided in the inner face of the slotted spline, while the lateral edge portions 46 of the expansion strip are adhesively secured in sealing relation to the underlying face portions of the adjacent panels 24-. Thus, the effective width of the sealing strip can be varied by adjustment in the depth of the bulbous portion to provide a continuous sealing relationship between the panels independently of the spline, as was more specifically described in theaforementioned copendiug application.
The. remaining difficulty resides in the blocking of the openings developed at the intersections between three or four panels, and to provide a fluid-tight seal therebetween notwithstanding the relative movements between the panels in the direction toward and away from each other responsive to expansions and contractions which normally take place in use.
Thus, it is another object of this invention-to provide a means and materials for effecting a block at the intersections between panels and to provide an expansion joint which eifects a fluid-tight seal "between the panels notwithstanding relative movements of the panels in expansion and contraction.
In accordance with the practice of this invention the desired relationship is efiected preferably after the linear splines 38 and expansion strips '40 have been installed.
Thereafter, a cylindrical opening 50 is routed out about a center which corresponds to the intersectionbetween the panels so that, in a 4-corner construction, a sector constituting about A of the cylindrical opening will be defined by the corner portions removed from each of the panels. 7 The opening 50 should be sufficiently large to intersect each of the splines leading into the intersection but not so large as to extend beyond the lateral edges integrity sufficient to maintain its unity upon fiexure of sections thereof which are secured for movement with adjacent panels. In the illustrated modification, the block to the base, it is desirable to fabricate the upper portion of materials which can be molded to a set stage. For this purpose, use can be made of wooden chips, such as chips of balsa Wood, mixed with a polyester or the like molding resin for bonding during the molding operation. When suitable dies and jigs are economical to provide, the com- 'ple'x curvature can be cut into the block, thereby to enable the entire block to be formed of laminated slabs or other wooden blocks.
The curvature at the top is such as to provide a cavity 58 in the central portion for enabling a bulbous section 60 in a corner expansion joint 62 to be received loosely therein to provide the same effect as the linear expansion strip 40, to provide for the compound movement's oc casioned by the relative movement between the plurality of panels making up the intersection. In the illustrated modification, the compound curvature in the upper portion of the block comprises the described cavity in the central portion and shallow valleys 64 or recessed portions of curvilinear shape extending continuously outwardly from the central cavity into endwise alignment with the splines to form a substantial continuation of the linear recesses formed therein. The areas 66 between the aligned recessed portions 64 are adhesively bonded to the adjacent walls 68 of the panel sections to tie in each quadrant of the block with its respective panel to effect a joint therebetween. Thus, movement of the panel in expansion or contraction will be directly transmitted to the attached section of the block which, when assisted by the separation from other sections by the recessed portion, will be able to flex for movement with the panel sections without destroying the integrity of the block.
The corner expansion joint 70 comprises a sheet material which can bemolded or otherwise formed to a desired shape. The sheet can be fabricated of various materials characterized by imperviousness to fluids and a flexibility or resiliency under the temperature conditions existing in use. For example, the corner expansion joint can be formed of a metal sheet or of a molded plastic or laminated sheet faced with a metallic film such as of aluminum or stainless steel. It can be formed of a resinous plastic capable of retaining its strength and flexibility at the low temperature conditions existing, or it can preferably be formed of such plastic or resinous material reinforced or further flexibilized by the incorporation of a fabric of glass or other suitable fibers. Instead, the expansion joint can be fabricated of a wooden sheet constructed of thin wooden cross-plies interbonded and edge of the sheet 70 for alignment with the grooves formed in the splines 38 and the bulbous portions 42 of the corresponding linear expansion joints 40' for establishing an interfitting relationship therewith, when in the assembled relation. Other recesses 76b extend up the side walls of the bulbous central portion between the recesses 76a to provide a continuous series of peaks and valleys arranged to extend perimetrically outwardly about the bulbous portion to permit compound movements in expansion and contraction as occasioned by the forces by relative movements of the panels interconnected to the expansion joint at the intersection.
The corner expansion joint is formed with flat body portions 80 extending outwardly beyond the bulbous portion of the grooves 76a and 76b to overlap the linear expansion strips 40 and part of the panels forming the intersection, and the overlying portions, including the overlapping interfitting grooves 78 and 42, are adhesively bonded one to the other to effect a fluid-tight seal therebetween. The central portion of the corner expansion joint is kept free of the adjacent surfaces to permit the desired flexure for expansion and contraction without the development of such forces as would disturb the sealing relation which has been established.
It will be understood that the various compound curvatures of the bulbous portion may take other arrangements and shapes, their purpose being to distribute the forces irn posed by the movements of the panels in expansion and contraction whereby the bulbous portion can flex to compensate for such movements without causing breakdown or the separation of parts. Ordinarily, the curvature of the underlying block will tend to correspond somewhat with the curvature of the bulbous portion so as to enable the bulbous portion to be received therein so that no portion of the expansion joint will project beyond the panels, whereby relatively flush surfaces are presented, In effect, the compound curvature in the face of the block will provide some backing and suport for the bulbous portion without interfering with the complex movements in the operation thereof.
It Will be understood that changes may be made with respect to the construction and composition of the various elements described and in their method of assembly in the insulation, and that other changes may be made in the details of construction and operation without departing from the spirit of the invention, especially as defined in the following claims.
