Description

Sealing and adiabatic tanks integrated into a polyhedral support structure

The present invention relates to a sealed and adiabatic membrane tank for storage and / or delivery of fluids such as cryogenic fluids.

Sealing and adiabatic membrane tanks are employed especially for the storage of liquefied natural gas (LNG) stored at atmospheric pressure at about-162 ° C. These tanks may be installed on land or on offshore structures.

In tanks for storage of cold liquefied gases, the essential function of the tank wall is to insulate the cargo to limit the flow of heat causing evaporation of the cargo and to protect the vessel from cryogenic temperatures in the case of tankers. However, the tank wall also has to withstand the hydrodynamic load of the cargo, which means resistance to compression.

One possible option for providing these functions is to fabricate the tank walls with a homogeneous layer of material that is structurally durable to insulation and compression. Examples of such tanks are available in the literature, for example in US-A-4116150 and WO-A-2013124573. However, the insulating materials employed in these examples, mainly reinforced polyurethane foam, are expensive. Moreover, it is difficult to find structural insulation materials that optimize mechanical strength and insulation.

Another possible option is to manufacture the tank wall with heterogeneous insulating blocks comprising an insulating material arranged between mechanically rigid supports and supports. In this case, since the insulating material is not subjected to a hydrostatic load at least partly, a wider selection of insulating material is possible. Examples of such tanks are available in the literature, for example FR-A-2867831, FR-A-2989291 and WO-A-2013182776.

In FR-A-2867831, the insulation block is a box with a parallel interior divider defining a compartment filled with expanded pearlite or aerogels. In FR-A-2989291 the insulating block is a similar box filled with a textile material. In one embodiment, a small cross-sectional filler is employed in place of the parallel wall. In WO-A-2013182776, it is provided to cast an insulating foam between the support pillars. Anyway, the overall heat flow delivered by this type of insulation block is the result of the flow delivered by the support and the flow delivered by the inserted insulation material.

The idea on which the present invention is based is to provide an array of tank walls in the vicinity of the corners connecting the two support walls forming an angle, in particular an obtuse angle.

Another idea based on the present invention is to provide an insulation block made of a thin material with at least some support portions having excellent mechanical strength in order to maximize the volume occupied by the non-structural insulation material.

Different types of materials of appropriate strength, such as plywood or synthetic materials, can be used for cover plates, floor plates and support pillars. The cover plate is preferably made of densified plywood. The densified plywood can be obtained as a layer of impregnated wood having a large amount of heat-treated resin, such as beech, fir or birch wood. The specific gravity of the densified plywood is preferably equal to or greater than 0.9. The typical specific gravity of ordinary plywood is about 0.7. This kind of densified plywood provides satisfactory properties in terms of price, mechanical strength and insulation. For example, the thickness of the cover plate may be about 5 mm. This can be similarly applied to a bottom plate that is generally subjected to less heavy loads.

In order to minimize the flow of heat by conduction, it is desirable to limit the cross-section of the support pillars. However, there is a risk of perforation of the cover and / or the bottom plate in the event of excessive concentration of compressive stress, since the support pillars are intended to absorb the water and hydrostatic loads and transfer them from the cover plate to the support wall. Moreover, the support pillars are prone to producing bending stresses in the cover and / or bottom plate. To reduce the risk of stresses and perforations, various load distribution elements may be employed in the connection between the support pillars and the cover and / or the bottom plate.

20 is a perspective view of a secondary edge insulating block and a primary edge insulating block employed in the corner region of FIG.
21 is a cutaway schematic view of a terminal for loading / offloading methane tankers and their tanks.

In Fig. 1, walls of sealing and adiabatic tanks are shown. The general structure of this kind of tank is already known and has a polyhedral shape. It will therefore be understood that only one wall area of the tank is described, and that all the planar walls of the tank can have a similar general structure.

Thus, the terms "upper" or "upper" refer to the position in which the tank wall is oriented toward the interior of the tank in the thickness direction of the tank wall, That is, toward the support structure.

The wall of the tank is formed from the outside to the inside of the tank by the supporting wall 1 and the secondary insulating barriers 2 formed by the juxtaposed secondary insulating block 3 of the supporting wall 1 and fixed by the fixing member 4 A secondary sealing membrane 5 provided by an insulating block 3 and a juxtaposed primary insulating block 7 of a secondary sealing membrane 5 and fixed by the fixing member 4 to the supporting wall 1, And a primary sealing membrane 9 provided by the primary insulation block 7 and intended to contact the cryogenic fluid contained in the tank.

Figure 1 shows the locations of four mutually adjacent secondary insulation blocks 3 at the corners. The tank wall is shown at various stages in each location. The first position does not include any insulating block, the second position includes the complete secondary insulation block 3 and the cut second sealing membrane 5, and the third position is complete A second primary insulation block 3, a complete primary insulation block 7 and a cut primary seal membrane 9, the fourth location comprising a cut secondary insulation block 3, (7).

The support structure includes a plurality of support walls defining the overall shape of the tank. The support structure may in particular be formed by a ship's hull or double hull. The support wall 1 may in particular be a stand-alone metal plate, more generally a rigid bulkhead type with suitable mechanical properties.

The primary sealing membrane 9 and the secondary sealing membrane 5 are, for example, constituted by a continuous layer of metal struts with protruding edges, which are arranged parallel to one another, By the protruding edge thereof. Metal stray keuneun example Invar®, that is the expansion coefficient is typically 1.2x10 ^-6 to 2x10 ^-6 K ^-1 is an iron and nickel alloy or a coefficient of expansion typically from about 7x10 ^-6 K ^-1 at a high having a manganese content of Iron alloy. In the case of marine tanks, the strake is preferably oriented parallel to the longitudinal direction 10 of the ship.

The secondary insulation block 3 and the primary insulation block 7 have a similar structure. Each insulating block 3, 7 has a rectangular parallelepiped shape. The two insulating blocks have the same length and the same width. The secondary insulation block (3) is thicker than the primary insulation block (7).

The secondary insulation block 3 includes a bottom plate 15 and a parallel cover plate 16 spaced apart in the thickness direction. The cover plate 16 has a support outer surface which allows the receiving of the secondary sealing membrane 5. The cover plate 16 is provided with a groove (not shown) having an L-shaped cross section in which a recess is formed to receive a weld support 11 enabling welding of the metal strut 12 of the secondary sealing membrane 5 8).

Typically, the longitudinal direction of the secondary insulation block 3 or any of the insulation blocks described below is parallel to the weld support 11.

The support pillars 17 extend in the thickness direction of the secondary insulation block 3 and are connected to the bottom plate 15 on the one hand and to the cover plate 16 on the other. The support pillars 17 allow the compression force to be absorbed. The support pillars 17 are arranged in a plurality of rows and arranged in a quincunx shape, here having a total of seven support pillars. The distance between the support pillars 17 is determined to enable a good distribution of the compressive force. In one embodiment, the support pillars 17 are distributed substantially equidistantly. The support pillars 17 are joined to the bottom plate 15 and the cover plate 16 by any suitable means, e.g., by screws, clips and / or adhesives.

In the embodiment shown in Figure 1, the support pillars 17 have a rectangular solid cross-section. The corner pillars 18 are also provided at the four corners of the bottom plate 15 and the cover plate 16.

The corner fillers 18 are two orthogonal webs,

A bisector web 19 oriented at 45 degrees between the longitudinal side and the transverse side of the bottom plate 15,

- a T-shaped cross-section formed by a counter-bisector web 19 oriented at right angles to the bi-sector web 19 and extending tangentially at the inner end of the bi-sector web 19.

In one embodiment, the bi-sector web 19 consists of a 9 to 10 mm thick plywood having a length of 100 mm and a height corresponding to the thickness of the insulating barrier. The counter-sector web 20 is made of 12 mm thick plywood having a length of 200 mm. This type of plywood thickness is already available as a standard. Alternatively, densified plywood may be employed.

In the secondary insulation block 3 of Figure 1, the bi-sector web 19 of the corner filler 18 is shown to have a trapezoid with a wide top and narrow bottom so that the outer edge of the bi-sector web is tilted. The rectangular cutout 21 is formed at each corner of the cover plate 16 to partially penetrate the thickness of the cover plate 16 so as to form a counterbore type surface on the cover plate. The horizontal upper edge of the bi-sector web is covered by the cover plate 16. The horizontal upper edge of the bi-sector web 19 is disposed below the counterbore type surface 50. This counterbore type surface allows the secondary metal plate 22 of the fixing member 4 to be supported.

The support pillars 17 and the corner pillars 18 may be made of a plurality of materials. They are especially suitable for use with conventional or densified plywood or polyvinyl chloride (PVC), polyethylene terephthalate (PET), polyethylene (PE), acrylonitrile butadiene styrene (ABS) copolymer, polyurethane (PU) or polypropylene Can be made of the same, optionally plastic-reinforced plastic material.

The insulating lining (13) extends in the space defined between the support pillars (17). The insulating lining is a polymer foam such as glass wool, cotton felt, polyurethane foam, polyethylene foam or polyvinyl chloride foam. This type of polymer foam can be inserted between the support pillars 17 during the fabrication of the secondary insulation block 3. Alternatively, the insulating lining can be made by providing an orifice for receiving the support pillars 17 in a pre-cut polymer foam, glass wool or cotton filler block.

The primary insulation block 7 has an overall structure similar to the secondary insulation block 3 except for some differences to be described later.

1, in the configuration in which the support pillars 24 and the corner pillars 25 of the primary insulation block 7 are laminated on the support pillars 17 and the corner pillars 18 of the secondary insulation block 3, The car bottom plate 26 and the secondary cover plate 16 are not subjected to a bending or shearing load. Basically under a hydrodynamic load, the primary cover plate 27 is subjected to a bending load while the support pillars 17, 24 and the corner pillars 18, 25 are subjected to a compressive load.

On the other hand, the primary bottom plate 26, the secondary cover plate 16 and the secondary bottom plate 15 receive less load, that is, they receive a load by essentially loading the ship's ballast, Lt; RTI ID = 0.0 > associated with < / RTI > Thus, the useful thickness of the structural element can be reduced to improve the thermal performance of the wall by providing a larger volume for the insulating lining.

It is therefore particularly advantageous to use structurally rigid and thin materials, such as densified plywood or synthetic material, for the primary bottom plate 26, the secondary cover plate 16 and the secondary bottom plate 15.

A suitable example of densified plywood is a material having a product code, for example ML 15 and ML 20, distributed by the company RANCAN srl under the trademark RANPREX®. These materials can be employed in thicknesses between 4 and 24 mm, without exceeding 12 mm, especially in the region of low pressure force. In any case, the thickness of the densified plywood is maintained to be less than the thickness required to obtain equal strength with the non-densified plywood.

1, the support pillars 17 of the secondary insulation block 3 are directly supported by the bottom plate 15 and the cover plate 16.

In order to improve the distribution of the load of the support pillars 24 in the primary insulation block 7, the structure is provided at the connection between the support pillars 24 and the cover plate 27. In Fig. 1, the longitudinal beam 28 is disposed at the top of each row of support pillars 24.

The fabrication of large support walls, such as the ship's hull, does not provide a perfectly flat surface. Therefore, in order to align the secondary insulation block 3 with a small tolerance, so as to obtain an excellent flatness of the supporting wall 1 in general and a very uniform supporting surface with respect to the secondary membrane 5, It is necessary to provide a shim 29 and a polymerizable mastic support beneath the bottom plate 15 of the block 3.

These polymerizable mastic supports may have a variety of configurations. Figure 1 shows an embodiment in which the polymerizable mastic support section comprises a dab 30 of mastic perpendicular to the support pillars 17 and a corner strip 31 in the form of a T- Fig. Thus, while minimizing the bending force of the bottom plate 15, it is possible to provide a total cross-section of a fairly small mastic support, which limits the heat conduction through the mastic supports. The cross-section of the dock 30 of the mastic is, for example, circular.

A non-adhesive, e.g., kraft paper sheet 14 is disposed on the inner surface of the support wall 1 to prevent the mastic from adhering to the support wall 1.

The entirety of the above description relating to the secondary insulation block 3 is also applicable to the primary insulation block 7. [ The only primary insulation block 7 differs in part from the secondary insulation block 3, in particular in the bottom plate 26. So that the bottom plate 26 need not include a mastic support. On the other hand, it is necessary to form the bottom plate 26 to fit the protruding portion of the secondary membrane 5, that is, the protruding edge of the strike 12 and the vertical wing of the weld support 11. [

As shown in Fig. 1, the bottom plate 26 can be divided to allow protrusions of the secondary membrane 5 to enter the gap. The connecting piece (32) is used to partially retain the bending resistance of the bottom plate (26). The connecting piece 32 of the bottom plate is, for example, a rod having an outline which is coupled across two successive portions of the bottom plate 26 parallel to the gap and which is characterized by a longitudinal groove parallel to the gap.

Since the bending force is generally higher in the primary cover plate 27, it is desirable to make the secondary cover plate 16 stronger and / or thicker than the secondary cover plate 16. The groove 33 of the weld support for the primary sealing membrane 9 can be machined to that thickness in a known manner.

1, the fixing members 4 arranged at the neighboring corners of four secondary insulation blocks (one of which is omitted) 3 simultaneously cooperate with the respective supporting structures to fix them. This applies equally to the four primary insulation blocks (two of which are omitted).

In the primary insulation block 7 of FIG. 1, the corner filler 25 includes a bi-sector web 34 and a counter-sector web 37. The bi-sector web 34 has been shown to have a different shape, with the outer edge of the bisector web having a wide lower portion and a narrower upper portion to have a horizontal shoulder surface 35. A rectangular cutout 36 is formed in each corner of the cover plate 27 to expose a horizontal shoulder surface 35 of the bisector web 34. This revealing horizontal shoulder surface allows the reception of the support engagement of the primary metal plate 38 of the fastening member 4. [ The shoulder surface 35 can perform the same function by tilting.

The rectangular cutout 36 formed in the corner of the cover plate 27 enables access to the fixing member 4 to facilitate its installation. These windows after installation can be blocked by the teachings of FR-A-2973097, for example.

An embodiment of the fixing member 4 will be described with reference to Fig. The main rod 39 has a threaded bottom end 40 to which a nut 41 received in a hollow base 42 welded to the support wall is screwed. Thus, the nut 41 received in the hollow base 42 fixes the lower end of the main rod 39 to the support wall and provides a first ball joint connection having a range of angular motion of about 10 degrees.

The secondary metal plate 22 is supported by a coupling cage comprised of a lower plate 44 coupled in parallel under the secondary metal plate 22 by four spacer tubes disposed at the corners of the lower plate 44 39). The secondary metal plate 22, the spacer tube 45 and the lower plate 44 are joined by four engagement screws 46 that engage the spacer tube 45.

The coupling cage includes a central bore 47 through which the main rod 39 passes and a nut 48 which is screwed into the upper end 43 of the main rod 39 between the lower plate 44 and the secondary metal plate 22 To the upper end (43) of the main rod (39) by means of a lower plate (44).

The laminate of the plate washer 49 engages the main rod 39 between the lower plate 44 and the nut 48 to enable the elastic movement of the coupling cage relative to the main rod 39. The secondary metal plate 22 includes a central opening 51 for installing a stack of plate washers 49 and a nut 48.

A central bore 47 through which the main rod 39 passes provides a secondary ball joint connection between the main rod 39 and the secondary metal plate 22 with a range of angular motion of about 10 degrees. By means of the two ball joint connections the secondary metal plate 22 can be arranged horizontally in the cover plate 16 of the four mutually adjacent secondary insulation blocks 3 while the secondary insulation block 3, The tolerance of the position of the secondary insulation block 3 is accepted so as to be stably fixed.

A stop tongue 50 coupled to the nut 48 is mounted on the two spacer tubes 48 to prevent inadvertent rotation of the nut 48 relative to the main rod 39 changing the clamping torque. (45).

To cooperate with the primary insulation block 7, the fastening member 4 further comprises a cap 52 which closes the central opening 51 and has a threaded hole 53 at the center thereof. During use, the secondary membrane (5) passes over the secondary metal plate (22) and the cap (52). The flanged pin 54 is screwed into the threaded hole 53 and locally pierces the secondary membrane 5 which is then welded to the secondary membrane 5 around the entire bore, .

The primary metal plate 38 engages on the flange pin 54 and is secured to the latter by a nut 55 and a plate washer 56.

To prevent unintentional rotation of the primary metal plate 38 relative to the flanged pin 54, the two stop pins 57 engage through the bores of the primary metal plate 38, Sector webs 34 of the first and second bushes 7, respectively.

The configuration described with reference to Figure 1 relates to the planar region of the tank wall and employs a current point insulating block, i.e., a second current point isolation block 7 and a first current point isolation block 3 do.

Referring to Figures 3 to 13, the corner areas of the tank wall will be described along the edge 58 of the support structure connecting two adjacent support walls 1 forming a corner therebetween. Since the corner area of the tank wall is essentially symmetrical with respect to the bisector plane of that angle, only one tank wall in the corner area will suffice.

The secondary insulation barriers of the tank walls include longitudinal rows of the secondary edge insulation block 103 shown in Figure 3 and the primary insulation barriers of the tank walls are connected to the secondary edge insulation block 103 stacked on the secondary edge isolation block 103 And includes the longitudinal rows of the primary edge isolation block 107 shown in FIG. The elements of the edge isolation block similar to the current point isolation block have the same reference numbers as those increased by 100, and only the current point isolation block and other parts are described.

3, the heat of the secondary edge insulating block 103 is coupled to the supporting wall by two rows of the fixing member 4 described above.

The first row (not shown) of the stationary member, the location of which is indicated by numeral 59, is disposed along the longitudinal edge of the secondary edge insulating block 103 farther from the edge 58. Each of these fixing members cooperates with two secondary current-point insulating blocks 3 (not shown) and two secondary-edge insulating blocks 103 whose positions are indicated by dotted lines. The second row 60 of securing members as shown is disposed between the transverse edges of the secondary edge insulating block 103 at specific spacings from the longitudinal edges facing toward the edges 58. [

The secondary edge insulating block 103 will be described with reference to FIGS.

The secondary edge isolation block 103 is similar to the secondary current point isolation block 3 and includes two corner pillar 118, a vertically aligned side by side bisector web 119, Two rectangle cutouts 121, a column of support pillars 117 between the two corner pillars 118 and a center column of support pillars 117 between the two grooves 108.

The portion of the secondary edge insulation block 103 facing toward the edge 58 is different. The attachment region intended to receive the secondary metal plate of the securing member of the second row 60 is spaced from the latter along the transverse edge of the cover plate 116 and not the corner of the cover plate 116. [ These two intermediate attachment areas correspond to a rectangular counterbored surface 61 formed within the thickness of the cover plate 116.

The main support pillars 62 arranged in parallel perpendicularly to these two attachment regions have a U-shaped cross section in a plane perpendicular to the thickness direction. More specifically, the main support pillars 62 have two parallel longitudinal webs 63 spaced apart in a lateral direction with a free end facing outward, and two And a transverse web 64 coupled to an edge of the longitudinal web 63 and connecting the two longitudinal webs 63. In a manner not shown, the U shape may be changed to a F, H, or < RTI ID = 0.0 > u < / RTI > shape using a larger size longitudinal web 63 or a transverse web 64, .

The heat of the support pillars 117 is arranged between the two main support pillars 62 and the corner pillars 118 and the last row of the support pillars 117 is aligned with the longitudinal edges facing towards the edges 58, And is arranged in the peripheral region of the secondary edge insulating block 103 between the pillar 62 and the secondary edge insulating block 103. This peripheral area corresponds to a longitudinal counterbore type surface 65 that extends over the entire length of the secondary edge isolation block and is defined by the step 66 of the cover plate 116.

3, the function of the longitudinal counterbored surface 65 is to receive the secondary corner beam 67 disposed in parallel with the edge 58 to support the secondary sealing barrier. The secondary corner beam 67 is parallel to the edge 58 disposed on each side of the bi-sector plane of the two supporting walls 1 and is parallel to the edge 58 of the secondary edge insulating block 103 of the longitudinal counter- And two extension wings (69) respectively seated on the cover plate. The secondary corner beam 67 is made of, for example, Invar < (R) >, and is arranged across the two extending wings 69, (68).

An insulating material such as a block 70 of glass wool is placed on the secondary edge insulating block 103 under the secondary corner beam 67 in order to limit the gap that can promote heat transfer by the natural convection of the secondary insulating barrier. As shown in FIG. The block 70 of insulation material has, for example, a wedge-shaped cross-section as best shown in FIG.

Figure 6 shows the fabrication of the secondary sealing membrane 5 in the corner region. On the other hand, the weld support 11 is inserted into the groove 108 of the secondary edge insulation block 103 and welds the metal strike 12 with the edges protruding according to known techniques. On the other hand, a half-strake 71 is disposed between the weld support 11 and the metal angle iron 68 closest to the edge 58 and the adjacent projected Has a projected edge welded to be sealed to the edge and a flat longitudinal edge 72 welded to be sealed to the metal angle iron 68 to cover the heat of the engagement screw 73. In the fastening member 60 of the row 60, the flanged pin 54 is disposed through the half-strike 71 over almost half its width.

The flanged pin 54 enables the securing of the primary edge insulating block 107 stacked on the secondary edge insulating block 103, as best seen in FIG.

The primary edge insulating block 107 will be described with reference to FIGS. The primary edge isolation block 107 is similar to the primary current point isolation block 7 and comprises a rectangular cutout 136 perpendicular to the shoulder surface 135 and two And a corner filler 125. There is a row of support pillars 124 between the two corner pillars 125 and a center column of support pillars 124 between the two grooves 133. Furthermore, the bottom plate 126 is divided into three sections to form a gap for receiving projections of the secondary sealing membrane 5. The connecting piece 132 attaches the three parts to each other.

The portion of the primary edge isolation block 107 facing toward the edge 58 is different. The primary support pillars 74 intended to receive the primary metal plate 38 are disposed at the ends facing toward the edges of the two transverse edges of the bottom plate 126. They have a U-shaped cross section in a plane perpendicular to the thickness direction. More specifically, the main support pillars 74 include two transversely spaced longitudinal webs 75 having a horizontal shoulder surface 76 at the free end facing outwardly and a first edge insulating block 107 And a transverse web 77 connecting two longitudinal webs 75 joined to the edges of the two longitudinal webs 75 facing towards the interior of the transverse web 75. The two horizontal shoulder surfaces 76 of the main support pillars 74 enable stable reception of the support engagement of the primary metal plate 38 of the fixation member of the heat 60.

In a manner not shown, the U shape may be changed to an F, H or mu shape by using a larger size one-way longitudinal web 75 or a transverse web 77, .

The primary edge insulating block cover plate 107 includes a continuous covering web 78 with a recess formed therein that is disposed in a network of beams having a thickness greater than the covering web 78. The network of beams thus coupled to the tops of the support pillars 124, corner pillar 125 and main support pillars 74 is better illustrated in FIG. 9 in which the covering web 78 is omitted.

9, the beam network includes a series of five transverse beams 79 extending over a portion of the width of the primary edge isolation block 107 from the longitudinal edge farther from the edge 58. As shown in FIG. The two transverse beams 79 are seated on the support pillars 124 in the middle row and the corner pillars 125 and extend in the longitudinal direction of the primary edge isolation block 107. The three transverse beams 79 disposed between the latter are disposed between the corner pillars 125 and extend between the support pillars 124 ending in the longitudinal direction of the primary edge insulation block 107 and the support pillars 124 124, respectively. A narrow longitudinal beam 85 extends between the two corner pillars 125 at the latter end.

At the end of the transverse beam 79 facing toward the edge 58 a wide edge beam 80 extends longitudinally and extends to the secondary longitudinal edge along the remainder of the width of the primary edge insulating block 107 And is seated on the two main support pillars 74. As shown in Fig.

The wide edge beam 80 has an inner transverse portion 81 covered by a covering web 80 having a length slightly longer than the bottom plate 126 and having a length slightly shorter than the bottom plate 126. The wide edge beam 80 also has an outer transverse portion which is shortened by two recesses provided at two longitudinal ends and which is located at the shoulder of each of the two main support pillars 74, To form an access window that allows access to the surface 76.

The top surface of the outer transverse portion 82 is not covered by the covering web 78, which ends at the edge 83. Thus forming a longitudinal counterbore type surface that is blocked in the thickness direction against the top surface of the covering web 78.

As best shown in FIG. 8, the covering web 78 can be composed of two overlapping sheets. In the cutout 136, the top sheet has a slightly wider cutout to define the edges around the access window. Alternatively, these edges may be machined to the same sheath thickness. With regard to this kind of edge, see FR-A2973097.

7, the function of the counterbored surface formed by the longitudinal portion 82 of the primary edge isolation block 107 is similar to that of the secondary corner beam 67, To receive the primary corner beam 86 that supports the primary sealing barrier. The primary corner beam 86 is disposed on each side of the bi-sector plane of the two support walls 1 and has a corner 58 that is seated on the cover plate of the primary edge insulation block 107 across the site 82, And two extending wings (87) parallel to each other. The primary corner beam 86 comprises a metal angle iron 88 made of, for example, Invar® and disposed across the two elongated wings 87 and screwed to the latter on each side of the bisector plane.

A block 89 of insulating material, such as a glass wool, is placed underneath the primary corner beam 86 in order to limit the gaps that can promote heat transfer by natural convection in the primary insulation barrier, As shown in FIG. The block 89 of insulation material has, for example, a wedge-shaped cross section as shown in FIG.

Figure 11 shows the production of the primary sealing membrane 9 in the corner region, which is essentially the same as the secondary sealing membrane 5. On the one hand, the weld support is inserted into the groove 133 of the primary edge insulation block 107 and welds the metal strip with the projected edges according to known techniques. On the other hand, the half-strike 71 is disposed between the welding support closest to the edge 58 and the metal angle irons 88, and has a protruding edge welded to be sealed to the neighboring protruding edge of the strut, And has a flat longitudinal edge 72 welded to be sealed to the angle iron 88 to cover the heat of the fixed screw.

12 and 13 are sectional views of the corner regions of the tank wall described above. The primary edge isolation block 107 is shown to be narrower than the secondary edge isolation block 103. Thus, although the longitudinal edges of the two stacked edge blocks are aligned on the side farther from the edge 58, the secondary edge isolation block 103 is closer to the edge 58 than the primary edge isolation block 107 It extends far.

Furthermore, it is shown that the support pillars of the two stacked edge blocks are aligned. Particularly, the main support pillars 74 are accurately stacked on the main support pillars 62, and the corner pillars 125 are accurately stacked on the corner pillars 118. This alignment is achieved by using the same fixing member 4 and by using a simple and balanced structure with respect to these fixing members 4, in particular by using an orientation perpendicular to the supporting wall 1, (103) and the primary insulating block (107).

Due to the symmetrical structure of the tank wall with respect to the bi-sector plane B, there is a specific exclusion area in the vicinity of the bi-sector plane B, which means that the fixing member 4 can not be disposed. This exclusion area further increases as the height of the fixing member becomes higher in the thickness direction of the tank wall. The secondary edge insulation block 103 is formed by a portion of the width L extending in the direction of the edge 58 beyond the row of the fixing member 60, notwithstanding the distance between the edge 58 and the column 60, Sector plane B can be arranged close to the bi-sector plane B sufficiently. This enables a relatively simple construction of the secondary sealing membrane 5 at the corners, by means of the corner beam 67 directly seated on the secondary edge insulating block 103 at each side of the bi-sector plane B only do. The same simplification appears in the production of the primary sealing membrane 9 in the corner region.

In order to optimize the fabrication of large tank walls, it is desirable to use standardized insulation blocks with items of differing sizes that are as limited as possible. However, it is necessary to take into account the manufacturing tolerances of the support wall 1, which typically ranges from a few centimeters to several tens of centimeters from the hull angle of the ship.

One possibility for this is to place a first longitudinal row at the mid-height of the support wall 1 and by adding successively parallel rows of equidistant spacers of the fixing member 4 when approaching the edge 58, So as to form a regular rectangle engaged with the fixing member 4. Number 59 corresponds to the end of these equally spaced successively parallel rows. The distance between the two rows is the width of the current point isolation block described with reference to FIG. The last column 60 is arranged as a function of the dimensions of the edge isolation blocks 103,107.

When the theoretical dimensions of the supporting wall 1 are known, the number and position of these columns of the fixing member 4 and the corresponding number of columns of the current point insulation block can be determined in advance. Due to the manufacturing tolerances of the support wall 1 there is nevertheless room for uncertainty in relation to the remaining distance D between the last row 60 and the edge 58 (see FIG. 1).

Figures 12 and 13 illustrate two examples in which the remaining distances are larger and smaller than the intended nominal distance, respectively. The relatively large width of each of the counterbore-type surfaces 65, 65 accommodating each of the secondary corner beam 67, the primary corner beam 86, ensures that such room of uncertainty can substantially To be absorbed by changing the relative position of the corner beam of the edge insulating block without changing it.

In the case of Figure 12, each of the secondary corner beam 67 and the primary corner beam 86 are arranged so as to cover a more limited area of each of the portion 82 of the cover plate and the counterbore type surface 65, Lt; / RTI > Additional strips 90 may be added to the same thickness as the wings of the corner beams, respectively, to cover the counterbore type surface 65, the remaining portion of each of the portions 82, respectively. The additional strips can be cut into a length of function of the exact dimensions of the supporting wall 1 concerned.

An additional strip 90 is not shown in Fig. 13 where the corner beam and the edge insulating block are superimposed to the greatest extent.

The dimensions of the edge insulation block and the number of support pillars of each primary or secondary edge insulation block may be varied as a function of the degree of load to be absorbed and the dimensions of the tank. In another embodiment (not shown) of the tank wall in the corner area, the edge insulation blocks 103, 107 are approximately half the previous width. In addition, the two rows of fasteners must satisfy this reduced spacing. The bottom plate 126 is divided into two parts only.

In a variant embodiment (not shown) of the secondary edge insulation block 103 and / or the cover plate 116 of the primary edge insulation block 107, each cover plate consists of one piece from a thicker sheet of plywood .

Referring to Figs. 14 to 16, a second embodiment of the tank in the 135 DEG corner area will be described. Elements similar to those of Figs. 3 to 13 have the same reference numerals, and only portions different from those of the first embodiment will be described.

14, a row of the secondary edge block 103 and a row of the primary edge block 107 stacked on the latter are provided, and the edge 58 and the bisector plane B And is disposed at a greater distance. The secondary support block 62 of the secondary edge block 103 is positioned at the end of two lateral edges facing toward the edge 58 since the secondary edge block 103 need not be as close as possible to the edge 58 And a part of the width L of the secondary edge block 103 of the first embodiment extended in the direction of the edge 58 is omitted.

For example, a rectangular box insulation box area 91 filled with pearlite or glass wool is added between the secondary edge block 103 and the edge 58. The rectangular parallelepiped insulation box section 91 is attached to the support wall 1 by means of a mechanical coupler, as indicated by the numeral 92, in cooperation with the transverse board according to known techniques.

The recess 284 extends over a portion of the length of the outer portion 282 and the length of the inner portion 281.

As in the second embodiment, the heat of the support pillars 324 is disposed below the edge beams 280 between the two main support pillars 274. The edge beam 280 thus enables the transfer of high pressure loads from the primary sealing membrane (not shown) to the support wall 201 through the two main support pillars 274, 262 and the support pillars 324, 317 .

As in the second embodiment, the outer portion 282 not covered by the covering web 278 is a portion of the outer edge 282 extending beyond the primary edge block 307 in the direction of the edge to support the primary sealing membrane. 2 < / RTI > rectangular bridging plate 296. In this manner, 18, the outer portion 282 of the edge beam 280 is configured such that the total depth of the counterbored surface in the assembled state of the cover is equal to the sum of the thickness of the covering web 278 and this thickness difference, 281).

In the third embodiment, the connecting ring has a standardized size and the room of uncertainty present due to the manufacturing tolerances of the supporting wall 201 is such that the distance between the last row of the fixing member 204 and the rectangular box isolation box sections 291, 295 Distance. Thereby, the rectangular bridging plates 294, 296 can be cut to a size of a function of the exact dimension of the associated support wall 201.
