Embodiment
On Fig. 1, can partly see sealing heat-insulated container 1, described sealing heat-insulated container is comprised of the container wall 2 and 3 on the internal surface of the corresponding wall 4 that is fixed on bearing structure and 5.Bearing structure for example is the inner housing of double hull boat or the building that is positioned at ground.For holding cold product such as GNL, container wall comprises at least one sealing barrier 6 and at least one heat shield 7.For considering of safety, can be at bearing structure and be called as in this case the secondary sealing barrier that does not show is set between the sealing barrier 6 of primary seal barrier.
Container 1 can be implemented according to known different geometries, for example prismatic geometrical shape in ship hull or on the ground cylindrical body geometrical shape or other.In addition, many methods can be used for implementing heat shield and sealing barrier, for example utilize prefabricated elements to implement heat shield and sealing barrier.
In the diapire 3 of container, elongation shape rigid member is shown, described elongation shape rigid member consists of leg 10, and it passes heat shield 7 and sealing barrier 6 extends, so that an end portion supports is on the diapire 5 of bearing structure and the other end protrudes out in the container away from sealing barrier 6.Leg 10 can for example be used for supporting the equipment 9 that should be immersed in container.For example, for supporting drainage pump, leg can be disposed in the bottom of the container pumping bar that does not show.Although leg is shown here on the diapire of container, similar rigid member can be disposed in other position in the container in an identical manner, for example is used for interval or supporting member that arbitrary object is kept away from container wall.
For implementing sealing barrier 6, can use sheetmetal, sheetmetal has ripple, and ripple forms elastic region, to absorb thermal shrinkage and static pressure and kinetic pressure.The sealing barrier that this class is made by ripple sheet material or concave-convex grain sheet material was particularly described in document FR-A-1379651, FR-A-1376525, FR-A-2781557 and FR-A-2861060.Now with reference to Fig. 2 and Fig. 3 this possibility is launched to describe.
With reference to Fig. 3, sealing barrier 6 is comprised of a plurality of ripple sealing plates 11, described a plurality of ripple sealing plates so-called internal surface be used for contacting with fluid-phase.Sealing plate 11 is thin metal such as corrosion resistant plate or aluminium sheet elements processed, and these sealing plates are welding together at 12 places, overlapping edges zone between them.Welding is the welding of lap welding type, and its method was for example described in detail in patent documentation FR-A-1387955.Sealing plate 11 can with regard to sealing plate design in many ways with regard to the shape and size sizes so that welding region can be located in many ways.
Sealing plate 11 comprises on the surface within it and is called longitudinally by First Series ripple 15 and second series are called horizontal ripple 16, and the separately direction of described First Series ripple and second series ripple is vertical.The height of First Series ripple 15 is lower than the height of second series ripple 16.Therefore, ripple 15 is discontinuous at the infall 18 of itself and continuous ripple 16.Longitudinal ripple 15 and transverse wave 16 protrude to the inside of container 1.
Leg 10 has the revolution shape in rounded cross section here, and with part under the truncated cone shape 13, partly being connected to cylindrical upper section at less 17 places, end of its diameter divides 14 under this truncated cone shape.The bottom support that the diameter of part 13 is larger under the truncated cone shape is on the wall 5 of bearing structure.The thickness that part 13 is passed container wall under the truncated cone shape extends beyond sealing barrier 6 positions.Cylindrical upper section divides 14 to be sealed shut by circular plate 19, and circular plate 19 can for example be welded on cylindrical upper section and divide on 14 the inward flange that does not show.
For allowing leg 10 to pass through, the ripple sealing plate 11 of formation sealing barrier 6 is cut to define the square fenestra 25 around leg 10.For realize the continuity of sealing barrier 6 at fenestra 25 places, between leg 10 and sealing plate 11, implement the sealing assembling of connector element.Because the diameter of leg 10 is greater than the interval between First Series ripple 15, therefore with numeral 20 expressions, its directrix A and leg 10 some crossing longitudinal ripples are interrupted at fenestra 25 places.Similarly because the diameter of leg 10 is greater than the interval between the second series ripple 16, therefore with shown in the numeral 21, its directrix B is interrupted at the fenestra place that centers on leg with some transverse waves that leg 10 intersects.
In addition, as visible on Fig. 3, in fact, the size of fenestra 25 is greater than the diameter of leg 10, so that being in place of connector element is relatively easy.Therefore, the fenestra 25 of arranging in corrugated sheet can interrupt such ripple in a similar manner: the directrix that does not in fact have to intersect with leg of ripple is installed connector element in order to allow very near leg between these ripples and leg.
The center C of leg 10 is positioned between the directrix A of ripple 20 of interruption and between the directrix B of the ripple 21 that interrupts, more precisely the central authorities of these directrixes on Fig. 3.Because this location so that, the each string of a musical instrument along being shorter than leg 10 diameters of directrix A or B is crossing with leg 10.Thus, consider between the limit of fenestra 25 one and leg 10, should exist, in order to the space of connector element allow to be installed, this location of leg allows to interrupt each described ripple 20 and 21 in a distance, wherein said distance is shorter compared with such situation: this situation be directrix A or B along the maximum transverse size of leg, namely be its diameter under the situation of circular cross-section, intersect with leg.Therefore consider that these interruptions can reduce partly the pliability of sealing barrier and help partly its fatigability and its abrasiveness, thereby be favourable at the ripple that short as far as possible distance is interrupted sealing barrier.
Under the situation of circular cross-section, leg provides optimum effect in half distance between the ripple 20 that interrupts and the centering of half distance between the ripple 21 of interruption.But, also can consider other location and other sectional shape of leg.The principle that can be used at every turn adapting to the location of leg between ripple is to select such position: described position minimizes or the transverse dimension of the leg that reduces at least to intersect with the directrix of interrupting ripple.Specific distribution at the ripple of the geometry in particular of leg and/or film requires to interrupt under the situation of a plurality of ripples in different length, and the suitable Optimal Parameters that is used for adapting to the leg location can be to grow the length of interruption most or the cumulative length of the interruption that obtains.
On Fig. 3, fenestra 25 has square configuration, its convenient shape that sealing plate 11 is cut into expectation.But, also can implement other shape of fenestra, particularly according to the geometrical shape of leg.
To Fig. 8, will be described in now the detailed mode of execution of the container wall in the zone of leg 10 with reference to Fig. 4.This mode of execution particularly is suitable for the container that container wall comprises two sealing barriers and two heat shields.Sealing barrier 6 thereby will be called as the primary seal barrier.To only describe near the leg 10, container wall can be implemented according to the instruction of patent application FR-A-2781557 in addition.
Fig. 4 is at the described leg 10 of middle erection stage with around section half view of the substantially square container wall region of this leg.What expression was divided in the right side is that what left part represented is after these elements are installed before the element that secondary sealing barrier and main heat shield are installed.
For being connected to secondary sealing barrier, leg 10 comprises bracket panel body 23, and bracket panel body 23 is square, and is fixing in the height of the upper surface of the very thin secondary sealing barrier of correspondence and secondary heat shield 22 part 13 under the truncated cone shape.For being connected to the primary seal barrier, leg 10 comprises master body 24, and master body 24 is rounded, and is fixing in the height of the upper surface of the main heat shield 26 of correspondence part 13 under the truncated cone shape.Disk body 23 can be to implement with 10 one-tenth single unitarily formed modes of leg with 24.
Below bracket panel body 23, secondary heat shield 22 comprises glass wool filler 27, and glass wool filler 27 also has square gabarit.Below master body 24, main heat shield 26 comprises glass wool filler 28, and glass wool filler 28 also has circular gabarit.
Around filler 27 and disk body 23, utilize four gussets to implement secondary heat shield, secondary sealing barrier and main heat shield, one of gusset is visible in the right side of Fig. 4 part, figure notation is 30.One gusset 30 has L shaped stairstepping generally, with: L-shaped lower heat insulation block 31, it consists of an element of secondary heat shield 22; Flexible sealing coating 32, the L-shaped upper surface of its complete covering blocks 31; The L-shaped upper heat insulation block 33 less with size, it consists of an element of main heat shield 26.Upper block 33 aligns with the outer side surface of lower block 31, in order to the end edge that is positioned at lower block 31 and sealing coating 32 zones on the inward flange are exposed.Gusset 30 can be with coming prefabricatedly with glueing joint with the similar material of the material of instructing among the patent application FR-A-2781557, and described material is especially for urethane foam and the wood veneer of heat shield and be used for aluminium foil and the glass fiber compound material of secondary sealing barrier.
Four gussets 30 enclose the profile of filler 27 and disk body 23 by their inner side surface ring.The size of block 31 is designed to produce the space between them, these spaces are the form of four radial channels 34, and it is at every turn between the end face of two adjacent lower blocks 31.For guaranteeing the continuity of main heat shield 22, with a glass fibre membrane 35 each conduit 34 of filling.The porosity of the glass fibre of filler 27 and glass fibre membrane 35 is so that gas becomes possibility through the circulation of main heat shield 22, particularly in order to the nitrogen deactivation of container wall.
Fig. 6 illustrates the enforcement of secondary sealing barrier in leg 10 zones with plan view.For realizing secondary sealing barrier around the continuity of leg 10, four aluminium foils and fiberglass sealed composite material tape 36 is bonded on the bracket panel body 27 and the sealing coating 32 of gusset 30 on.One band 36 is oriented to overlap with the inward flange of the exposure of an avris of bracket panel body 27 and two lower blocks 31 at every turn.These are with 36 at the mutual crossover in end regions 37 places.For realizing the continuity of secondary sealing barrier above conduit 35, four aluminium foils and fiberglass sealed composite material tape 38 are bonded on the sealing coating 32 of gusset 30, overlap with the end edge with two lower blocks 31 at every turn.
Fig. 7 is illustrated in main heat shield same containers wall zone afterwards is installed.Blocks 41 are finished it utilizes four dihedral blocks 40 and four between upper heat insulation block 33 and leg 10 in the middle of, at every turn the fit circular contour of filler 28 and master body 24 of the inner side surface of these blocks.These blocks 40 and 41 also illustrate in the left part of Fig. 4.
As visible on the details of Fig. 5, the upper surface of middle block 41 has a groove 44 that is defined by a recess 43 at every turn.Groove 44 provides smooth supporting surface definitely at master body 24 height to give metal shrouding 45, and metal shrouding 45 is used for implementing the primary seal barrier around leg 10.
As visible on Fig. 7, two shroudings 45 around master body 24 arrange and whole week of master body along on seal welding in the master body.For this reason, shrouding 45 within it limit section 46 places is cut semicircular in shape, and that the edge portion 47 of shrouding defines is square, and this square size is slightly larger than the fenestra 25 that arranges in ripple sealing plate 11.Two shroudings 45 are stacked at regional 48 places, and these two shroudings are welded together at regional 48 places.The block 40 and 41 that shrouding 45 is fixed in main heat shield by being arranged near the shrouding edge portion 47 rivet or wood screw 49 is so that shrouding 45 is close to these blocks, particularly owing to need to avoid shrouding to dig during in 24 welding of master body shrouding.
Get back to Fig. 2 and Fig. 3, can see: on the one hand the limit section of the sealing plate 11 by will defining fenestra 25 is welded on the shrouding 45, by be sealed shut the ripple 20 of interruption and 21 end with termination case 50, in leg 10 zones, finish primary seal barrier 6 on the other hand.Enforcement comprises the shrouding 45 limit sections of screw 49 to the cutting of sealing plate 11 with covering.
One embodiment of termination case 50 is shown at Fig. 8.Termination case 50 comprises: be a base plate of two parts 51 and 52, described two parts are used for being welded on hermetically respectively on the shrouding 45 and sealing plate 11; With a housing 54, be used for being welded on hermetically the end of ripple 20 or 21.Recess 53 between the part 51 and 52 of base plate has the amplitude (amplitude) that substantially equals sealing plate 11 thickness.
For consisting of secondary heat shield, secondary sealing barrier and main heat shield in the heat insulation block shown in Fig. 2, Fig. 4, Fig. 6 and Fig. 7 and the cutting of other prefabricated elements, only be schematic.Can be according to other shape cutting and prefabricated similar components, so that the more or less basic component of the installation requirement of container wall.According to other mode of execution of correspondence, four L-shaped gussets 30 are substituted by two U-shaped plates or single plate with quadra shape.
As more clearly visible on Fig. 3, the leg of above considering needs such fenestra: the size of fenestra is approximately equal to the twice at the interval 55 between two ripples 15 or 16, and described ripple is equidistant here.For this reason, two of each series ripples are interrupted.But, near leg and the container wall this layout leg can be suitable for other size of leg.For example, for more roomy leg, corresponding fenestra can interrupt the ripple of the more more number in or each series, for example three or four ripples or more ripple.In addition, also can move partly the trend of some ripple, with restriction should interrupted ripple number, and thereby keep the higher spring level of sealing film.This possibility illustrates by the mode of execution of Fig. 9.
On Fig. 9, add that with identical figure notation 100 represent with the same or analogous element of Fig. 3 element.The transverse dimension of leg 110 is larger, for example more than or equal to approximately three times of the interval 155 between ripple 115 or 116, be disposed in the film of corrugated metal, in order to the fenestra 125 that leg 110 passes through, interrupt in this case the directrix of corresponding four ripples in each series.But, this mode of execution does not interrupt four ripples in each series, but as two ripples 120 interrupting each series, correspondingly 121 are set in the aforesaid mode of execution, and in addition two ripples 158 of each series, correspondingly 159 setover partly away from leg 110 with respect to its original directrix, but be not interrupted in a word.
For this reason, sealing barrier 106 is changed at concentric two square fenestras 125 and 160 places.Outside fenestra 160, sealing barrier 106 is comprised of the sealing plate 111 with the longitudinal ripple 115 that is equally spaced and transverse wave 116.Between fenestra 160 and fenestra 125, sealing barrier 106 continues mutually with other ripple sealing plate, other ripple sealing plate is the c-shaped ripple sealing plate 161 generally of two in this situation namely, they with distribute by different way, i.e. the nearer ripple in interval in this situation.Especially, the ripple of sealing plate 161 consist of for every ripple 158, correspondingly 159 away from a central segment section 162 of leg 110 biasings, correspondingly 163.At last, similar to the mode of execution of Fig. 3 in the structure of fenestra 125 places and the sealing barrier 106 of section within it.
For the central segment section 162 that implements ripple 158 or 159 or 163 with corrugated portion outside fenestra 160 between engage use bent member 170 at fenestra 160 places.
One embodiment of bent member 170 is shown at Figure 10.Bent member 170 comprises: a base plate, and it is two parts 171 and 712, and these two parts are used for being welded on hermetically respectively on the plate 111 or 161 of sealing barrier 106 and adjacent bent member 170; With curved elbow ripple 174, its directrix forms selected angle, for example 135 °.Curved elbow ripple 174 is used for being connected to hermetically the adjacent end portion of ripple 158 or 159 and the curved elbow ripple of adjacent bent member.Recess 173 between the part 171 and 172 of base plate has and substantially equals for making sealing plate 111 or 161 or the amplitude of the thickness of the sheet material of bent member 170.Preferably, adopt the sheet material of same thickness for these different members.
At another mode of execution that does not show, for example be suitable in another mode of execution of the less leg of diameter, fenestra interrupts all ripples of its directrix, two ripples of each series on for example Fig. 3, with ripple 158 and the 159 similar ground of Fig. 9, kept away (à travers) fenestra along the trend of biasing and prolonged.In this embodiment, the pliability of film can be improved, and this is because finally do not interrupt any ripple at leg place termination case.
In mode of execution mentioned above, the primary seal barrier is implemented with the sheet metal with orthogonal two serial ripples.But, can similarly use and have still less or more ripple and/or corrugated metal film with other type that different ripples arranges.
