Definitions
- the present invention essentially relates to a structural arrangement forming a corner construction for a wall with at least two intersecting or meeting sides or faces, having the configuration of a salient or re-entrant solid angle in space of any shape, projecting inwards into or outwards from the inner wall of a for example fluidtight and heat-insulated confining enclosed space, dening in particular a tank or the like, preferably of the so-called integrated type, as well as the method of making said arrangement and the various applications of the latter.
- Tanks are already known, which are adapted for example, but not exclusively, to the transport or conveyance and/ or to the storage and preservation of fiuids kept at a temperature very different from the ambient, normal or ordinary temperature, such as for example cryogenic or strongly cooled fluids and more especially liquefied gases at very low temperature and at a pressure approaching for example the ambient atmospheric pressure, such tanks being also able to be used at high temperatures and/ or pressures.
- Tanks adapted for such a purpose are advantageously of the so-called integrated type, such as for instance the tanks for transporting or conveying liquefied natural gases, such as liquid methane, directly incorporated into the hull of a transporting ship.
- Such a tank generally comprises an inner envelope, shell or casing, mostly made from metal-sheets or foils, of a metal such as stainless steel, capable of sustaining the low service or operating temperatures and forming a socalled impervious primary barrier, adapted to be in direct Contact with the contents.
- This primary barrier is relatively thin and exible or yieldable and preferably corrugated or creased, generally along at least two sets or systems of corrugations extending in substantially parallel spaced relationship in a same set or system and intersecting substantially at right angles the corrugations of the other set or system so as generally to form a kind of network of substantially orthogonal pattern the crests of corrugations of which are preferably all projecting from a same inner side or face of said metal-sheet.
- This primary barrier thus forms a kind of membrane bearing preferably in a substantially uniform manner against an outer surrounding supporting and self-carrying or rigid structure, constituted for instance by the ships hull and this, through the medium of at least one layer or sheet of heat-insulating materials or lagging, wherein may be JCC interposed or embedded at least one intermediate envelope, shell or casing, forming an impervious secondary barrier, surrounding or encompassing the primary barrier and of a configuration often similar thereto.
- This intermediate insulating material is thus adapted to transmit to the outer self-carrying supporting structure, all the forces exerted or applied on the primary barrier by the contents thereof or confined thereby.
- Such integrated tanks may of course exhibit any geometrical shape, but they frequently are of a substantially or approximately prismatoidal or parallelepipedic and even possibly cylindrical shape.
- These tanks generally embody wall corners formed by the intersection or meeting of two or more wall faces or sides. At each Vertex or apex of the geometrical solid body formed by the tank, the corresponding corner constitutes a solid angle formed by the intersection of three or more faces or sides converging towards or meeting at the common point forming the vertex or apex.
- the corner formed by said solid angle is polyhedral (for example trihedral in the case of a parallelepipedic tank), each pair of adjacent faces or side-walls of which forms a dihedron.
- the faces or wall sides forming said solid angle may also be skew, that is warped, curved, convex or concave surfaces and intersect each other along a curvilinear edge-line, the plane angle between two adjacent faces being then also curvilinear.
- the tanks more especially of a general prismatoidal or polyhedral and more particularly parallelepipedic shape may exhibit inner corners or solid angles, such as dihedron or trihedrals, which may be either salient or re-entrant.
- inner corners or solid angles such as dihedron or trihedrals, which may be either salient or re-entrant.
- the angular spacing or dihedral angle of each pair of adjacent faces of these corners or solid angles tends to vary, that is to open or increase or to close or decrease more or less under the inuence of inner or outer pressures applied to the wall, and this is a serious inconvenience.
- One main object of the present invention is to obviate or to remove such a drawback by providing a corner or solid angle construction rigid enough to be substantially nondeformable, that is to render substantially invariable the angular spacing of each pair of adjacent faces, forming for example a dihedron, or at the very least to obtain that any variation of this angular spacing.
- the invention is also concerned with the process of making the aforesaid construction, resulting from the design of the latter.
- the invention is also directed to the various applications and appliances resulting from the use or Working of constructions of the type broadly set forth hereinabove, as well as to the various constructions, systems and buildings which are provided therewith, such as preferably closed vessels or enclosures for example integrated into or combined with an outer self-carrying, stationary or movable support, and defining an insulated space for containing or confining a product, device or apparatus, such vessels or enclosed spaces forming in particular containers, tanks, vats, cisterns, reservoirs or the like for storing and preserving a product, erected at a stationary position or incorporated into transport or conveying vehicles of any kind, for example floating or rolling vehicles, as well as the safety, protecting or shielding casings, shells or vessels for nuclear plants and the nuclear reactor vessels, tanks or casings or the like.

- FIGURE 10 is a partial view in section taken upon the line X--X of FIGURE 9;
- FIGURE 11 is a fragmentary view in section taken upon the line XI--XI of FIGURE 9.
- the reference numeral 1 denotes a self-carrying outer supporting structure, formed for example by the double wall of a ships hull in the region of a corner 2 having the shape of a re-entrant dihedral angle inside of which is mounted the corresponding reentrant dihedral corner 2 of the integrated tank.
- the plane or straight angle of this dihedron is substantially orthogonal or right in the example shown, but it can of course be of any value, for example an obtuse or acute angle.
- it may have skew faces or possibly mixed or combined that is plane and skew faces.
- the rigid and solid structure of this angle 2 consists of a series or row of dihedral-shaped angular elements 3, preferably but not compulsorily all identical with each other, spaced from each other, facing towards the same direction and substantially aligned in a row extending along the edge of the dihedron 2.
- Such a breaking or dividing up or splitting of the solid structure of this dihedral angle 2 into several spaced elements, parts, portions, pieces or sections of a dihedron is necessary to allow the thermal deformations and strains of the impervious, relatively thin and flexible, membrane-like primary and secondary barriers which are adapted to be rigidly secured to the angular elements and in particular, the expansions and contrac- *ions parallel to the direction of the edge of the dihedron.
- each angular element 3 may possibly be made of one single piece, it is advantageous, to simplify the manufacture and mounting or erection, that each angular element 3 consist of two inner or primary and outer or secondary angle members 3a, 3b, respectively, which are overlying or coupled so as to be nested or fitted into each other.
- Each primary angle member 3a is made integral with the secondary angle member 3b which is associated therewith, for example by screws or the like 4 the head of which is preferably sunk or embedded in a counter-bored recess of the angle plate 3a, in order that it does not raise or project from the inner face of the angle plate.
- Each screw 4 is screwed in a blind threaded hole of the secondary angle plate 3b, so that in case of a breakage or failure of the primary barrier, no leakage can occur through the fastening holes for the screws.
- Each angular element 3 is supported by one or several supporting or carrier spacer blocks 5 consisting each one of a connecting cleat or dog or the like, made from a compact and heat-insulating material, such as for example plywood, compressed wood, laminated wood or the like.
- Each spacer block or cleat is adapted or designed to connect the angular element supported thereby to the outer rigid supporting structure 1, such as the doublewalled hull of the ship and is preferably recessed so as to minimize any heat transmitting bridges or conductive connections.
- Each spacer block or cleat 5 is secured to the inner wall of the outer structure 1, in the re-entrant dihedral corner thereof, by stud pins, bolts or the like 6, for example by means of studs welded to the Wall 1.
- Each cleat is thus applied edgewise against both faces of the dihedron formed by this wall 1 and extends between pairs of registering or opposite studs, disposed on either side of the cleat, respectively and holding same by means of clamping or tightening strips or bars 7, extending through a recess or cut-out portion of the cleat.
- insulating material may advantageously consist of a suitable synthetic or artificial material s uch as a foamed plastic material such as expanded polyurethane or the like, applied by spraying by means of a spray-gun or the like.
- each cleat 5 is cut out or shaped to conform to the angular element 3 to be supported thereby, that is, in the shape of a reentrant dihedral angle wherein the secondary angle plate 3b is applied thereagainst by its outer face which is thus conformed to by the cleat.
- Each secondary angle plate 3b is firmly atiixed or secured against each one of the cleats 5 supporting same, by one or several tie-rods, bolts or the like 8, fastened each one to the angle plate 3b.
- Each tie-rod consists desirably of an eye-bolt or the like, pivotally connected, through the medium of a pin 9 to a clevis, lug, bracket or like flange or member 10, integral with the angle plate 3b (FIGURE 3).
- Each bolt such as 8 desirably extends edgewise through the cleat 5 to project by its screw-threaded end adapted to receive a clamping nut, into a recess or cut-out of said cleat so that such nuts be easily accessible.
- the tightening of each nut against the edge of the corresponding recess or cutout portion of the cleat is desirably effected through the medium of a boat-shaped washer, a yoke or strap, a cramp, a clip or the like 11, conforming to the local shape ofthe edge of the recess or cut-out.
- the cleviscs 10 consist advantageously of a pair of substantially parallel stitfening or reinforcing members or lianges, welded to the outer face of the angle plate 3b and between which the corresponding cleat 5 is fitted. To avoid any deformation of the angle plate 3b when welding the stiffeners 10, the latter are provided with slots, notches or jags 12 along their edge bearing against the angle plate 3b.
- each angular element 3 When each angular element 3 is relatively long, it is supported by several spaced cleats, whereas when it is relatively short, it may only be supported by a single cleat disposed substantially in the medial transverse plane of the angular element.
- each cleat 5 is generally of a substantially flat shape, there is provided, to prevent any tilting of the angular element 3 transversely towards either side of the cleat, at least one pair and preferably two pairs of stiifening members or ribs 13, preferably consisting of the same material as the cleat 5 and bearing substantially at right angles against same on either side of said cleat.
- Each reinforcing member 13 also bears by one end thereof against the Wall of the structure 1 and by the opposite end against the outer face of the angular plate 3b.
- Each one of these reinforcing members 13 may be secured in a simple manner to the cleat 5, for example by at least one pair of connecting corner plates or angles 14 secured to the cleat 5 and to the reinforcing member 13 by bolts such as 15.
- each angle plate 3b is secured by three tie-rods 8 one of which is arranged in the bisecting plane of the dihedron and the two other ones are respectively at right angles to both flanges or faces of the angle plate 3b. In view of their pivotal connection, these two latter tie-rods are capable of swinging or pivoting within the corresponding recess or aperture of the cleat to follow the thermal deformations of the angle plate (see FIGURES 2 and 3).
- the metal sheets of the primary and secondary barriers 17 and 16, respectively, may assume the shape shown on FIGURE l, that is exhibit for example an orthogonal pattern of corrugations arranged in two intersecting systems, sets or series of parallel spaced corrugations dening therebetween smooth or uncormgated areas, for example substantially flat or plane and defined by a substantially rectangular or square contour.
- the patterns or configurations of the corrugations of both primary and secondary barriers, respectively, may be similar to or identical with each other or different from each other.
- the spacings or pitches of the corrugations of both barriers are substantially identical with each other, so that the corrugations of both barriers differ somewhat from each other by their shape and size.
- each secondary angle plate 3b comprises, on the periphery of each flange lthereof and on the Side of the inner face, a reduced, thinned or edged olf marginal portion, forming a rabbet or the like 18, machined into the angle plate to form thereby a marginal shoulder, recessed with respect to the inner face of the flange.
- a reduced, thinned or edged olf marginal portion forming a rabbet or the like 18, machined into the angle plate to form thereby a marginal shoulder, recessed with respect to the inner face of the flange.
- the barrier 16 is secured by welding, for example by an arc-welded lap-joint along its edge at 19.
- the secondary barrier is so directed that its corrugations, which are all projecting from a same side of the metal-sheet, are facing outwards.
- Each spacing or gap left between two successive angle plates 3b is covered from the outside by an angular piece 20, conforming to the shape of the angle plate 3b and preferably consisting of a sheet portion of the secondary barrier, so as to exhibit at least one corrugation extending in parallel relation to the spacing or gap between the two successive angle plates 3b and straddling such a spacing or gap.
- Each angle piece 20 covers by the ends of its flanges, the edge of the secondary barrier secured to the flanges of the angle plates 3b and is welded, for example arc-welded according to a lap-joint to said secondary barrier at 21. All the ⁇ welds are continuous and the covering or overlapping between the secondary barrier and the angle piece is achieved owing to the presence of a crease or the like, formed in each covering angle piece to take up or compensate for the thickness of the covered secondary barrier.
- each portion of covering metal-sheet or foil of an assembly with mutually overlapping edges preferably comprises such a crease or the like, known per se, corresponding to the thickness of the portion of covered metal-sheet or foil.
- Each angle piece 20 extends over the whole width of the flanges of each angle plate 3b and is secured to said angle plate outside of the covering or overlapping areas of the secondary barrier by a continuous well along its edge.
- Each primary angle plate 3a is preferably thinner than the associated secondary angle plate 3b and larger so as to protrude, for example along its whole periphery, in overhanging relationship beyond the secondary angle plate 3b.
- the primary barrier 17 is secured to the anges of each primary angle plate 3a, respectively, by screws or the like 22, screwed into strips or small plates or into a strip forming a backing pla-te, or the like, 23, fastened, as by welding, to the protruding portion of each flange of angle plate and behind or rearwards thereof, that is on the outside.
- the head of each screw 22 is preferably sunk or embedded in a recess or the like, machined, milled, counter-bored or cut in the inner face of the primary angle plate 3a.
- the screws 22 for fastening the primary barrier 17 to the primary angle plates 3a may be replaced by spot or tack welds, effected for example by arc-welding, such as 24, extending through the primary barrier 17, thereby avoiding any piercing or drilling thereof as well as the fastening of small plates 23.
- Inner or primary angle pieces 25, respectively homologous of the outer or secondary angle pieces 20 are provided to straddle the gaps or spacings separating the successive primary angle plates 3a.
- angle pieces 25 which are preferably made or taken from a primary barrier sheet-metal and comprise one corrugation bridging Ithe gap or spacing between two primary angle plates 3a, conform to the inside shape of the primary angle plates 3a and connect to each other the portions of primary barrier 17 secured to the anges of each primary angle plate, respectively.
- the central corrugation of each angle piece 25 is connected preferably by welding to the corresponding corrugation of the primary barrier, substantially in aligned or registering relation to this corrugation.
- each angle piece 25 is long enough, in parallel relation to the edge of the corner or dihedron so that the successive angle pieces are preferably alternately overlapping by their adjacent edges which are connected in sealing relationship by a continuous Weld along a lap-joint and also cover the edges of the secondary barrier at both ends of the flanges of the primary angle plates.
