Each midfeather structure 3917 has first surface (not shown) and the second surface (not shown) in the face of structural walls in the face of the first sealed wall 250. In one embodiment, the first surface of central dividing wall structure 3917 and the first sealed wall 250 or when any part that the first sealed wall becomes one contacted, the first surface of midfeather structure 3917 did not directly append on the first sealed wall 250. When the second surface of central dividing wall structure 3917 contacted with structural walls, it did not directly append on the structural walls. In one embodiment, midfeather structure 3917 interconnects each other, and forms a single integrated entity. Each midfeather structure 3917 comprises the module of a plurality of mutual connections. In other words, each midfeather structure 3917 can be individual module.

And then in other embodiments, can form the wet tank of the various shapes outside the sphere, and common sphere for example, cube, rectangle, ellipse, cylindrical etc. In other embodiments, wet tank can be formed on truck, train or other means of transport. Equally, in other embodiments, wet tank 3919 can form on the ground or be underground.

Further, the upper end of running through this lower support bar 60 of the second insulation barrier 53 and the second sealing barrier 52 is fixed on the upper surface of the second insulation barrier 53. With a hold-down nut 63 and the sealing barrier hold-down nut 64 that is fastened on lower support bar 60 upper ends the second sealing barrier 52 is fixed in lower support bar 60.

The second insulation barrier 53 and the second sealing barrier 52 are run through in the upper end of this lower support bar 60, and they are fixed on the first insulation barrier 51, and the lower end of the first insulation barrier 51 is run through and be fixed in the upper end of this lower support bar 60.

In other words, the first insulation barrier 51 contacts also with it fixed connection with the second sealing barrier 52 of fixing at the second insulation barrier 53 upper surfaces. The first insulation barrier 51 composed as follows: dull and stereotyped 55 once, contact with 52 of the second sealing barriers and with it fastening connection of adhesive; One first insulator 57 is positioned on lower dull and stereotyped 55 the upper surface; And a upper flat plate 54, with the fastening connection in upper plane of the first insulator 57. Dull and stereotyped 54 and 55 being made by many plywood up and down of the first insulation barrier, and the first insulator 57 is made by polyurethane foam.

At this moment, a connection reinforcement bar 90 be positioned at the first insulation barrier 51 lower dull and stereotyped 55 on, lower support bar 60 therefrom passes, thus a upper support bar that connects this lower support bar and will mention hereinafter. That is to say, the connection reinforcement bar 90 that is positioned on 51 times flat boards 55 of the first insulation barrier is passed in the upper end of running through the lower support bar 60 of the second insulation barrier 53 and sealing barrier 52, mutually clamps thereby connection reinforcement bar 90 can pass through one bolt-fastening nuts mode.

The lower end of a plurality of (in the accompanying drawing of the present invention being two) upper support bar 70 is by being inserted in the bar support cap 71, and be fixed to connection reinforcement bar 90, its king-rod support cap 71 is fixed on the bottom surface of connection reinforcement bar 90, for example, method with welding is fixed, and clamps this connection reinforcement bar 90 with clamp nut 72 again.

Therefore, run through the upper end of the lower support bar 60 of the second insulation barrier 53 and sealing barrier 52, and the lower end of running through the upper support bar 70 of the first insulation barrier 51 is firmly secured to connection reinforcement bar 90.

Here, angle support plate 50 is without adhesive, but is mechanically connected to the first insulation barrier 51, so this angle support plate 50 can slide at the first insulation barrier 51, though this angle support plate since heat can shrink and extend. Hereinafter will set forth one first sealing barrier 250, it is positioned on the angle support plate 50 also with it with being welded to connect.

Fig. 6 (b) has shown another example that upper support bar 70 is connected to the method on the angle support plate 50. That is to say, this upper support bar 70 run through the first insulation barrier 51 and on upper flat plate 54, and this upper support bar 70 is directly connected to angle supporting plane 50, thereby supports this angle supporting plane 50. At this moment, between the first insulation barrier 51 of upper support bar 70 and corner assembly, there is a little space, and between angle support plate 50 boxes the first insulation barrier 51, directly connects by adhesive. Therefore, this angle support plate 50 can be slided a little with respect to the first insulation barrier 51. The slip of this angle support plate can be offset between the first insulation barrier 51 and this angle support plate 50 because different to the contraction of variations in temperature and extension of different materials. Further, have benefited from above-mentioned structure, by the lower support bar 60 that is connected to tank inner surface, the upper support bar 70 that is connected to lower support bar 60, and be connected to the first sealing barrier that the angle gripper shoe 50 of upper support bar 70 can the firm support corner assembly. In addition, because this angle support plate 50 is made by a slightly thick flat board, it is enough to firmly the first sealing barrier of strut angle parts, and this first sealing barrier can produce asymmetric stress.

In addition, made by aluminium sheet or pliable and tough thin plate (flexible sheet (three-ply board Triplex)) according to the second sealing barrier 52 of corner structure 100 of the present invention. The second sealing barrier 52 is further outstanding from the side of the first and second insulation barriers 51 and 53, thereby is fixed in next process on one second sealing barrier 203 of a contiguous prefabricated planar structure.

Fig. 9 has shown a planar structure of building according to LNG tank of the present invention. With reference to figure 9, planar structure 200 of the present invention outside hull, finish prefabricated after, introduce in the hull. The structure of this planar structure 200 is similar to corner structure 100. In the case, at the upper part of the first insulation barrier 204 of this planar structure the upper flat plate 205 that plywood is made more than is installed.

That is to say, in this planar structure, once dull and stereotyped 201 contacting with 1 of the inner surface of hull on the second insulation barrier 202 of the planar structure of being made by polyurethane foam, by aluminium sheet or pliable and tough thin plate (flexible sheet (three-ply board, hard three-ply board triplex preferably, preferably rigid triplex)) the second sealing barrier 203 of making is connected with the upper surface of the second insulation barrier again, and the first insulation barrier 204 of being made by polyurethane foam be connected the upper flat plate 205 that many plywood make and be connected with the upper surface of the second sealing barrier 203.

And then, lower dull and stereotyped 201 and the second sealing barrier 203 of the second insulation barrier of planar structure outstanding a little from the side of the first and

second insulation barriers

202 and 204, thereby in next process, they can and be fixed with adjacent plane structure 200 or corner structure 100 interlockings. The opposite flange of this planar structure contacts with corner structure 100, and is configured to the shape of Partial Resection, thereby can make, and fixes with anchor structure 150 of the present invention. Planar structure 200 of the present invention has the height same with adjacent angular structure 100.

Hereinafter, will elaborate according to an embodiment of the invention a LNG tank and manufacture process thereof referring to accompanying drawing 10 to 23.

LNG tank of the present invention is installed on the bottom surface of hull, and one intersect or longitudinal division 2 meets at right angles from the bottom surface or predetermined angular to intersect or longitudinal direction extends.

At first, will be fixed on for its flange ledge 80 and 81 of fixed angles structure bottom surface 1 and intersection next door 2. At this moment, preferably this flange ledge 80 and 81 is welded and fixed, and with angular spacing one preset distance, thereby so that prefabricated corner structure can insert into this space. After corner structure 100 has inserted between flange ledge 80 and 81, between this corner structure and this flange are outstanding, form some spaces.

Shown in Figure 10 to 12, if corner structure 100 is installed between flange ledge 80 and 81, a fixed pivot 101 is fixed between flange ledge 80 and 81. At this moment, this fixed pivot 101 preferably with this flange ledge 80 with are connected bolt and are connected. The fixed pivot 101 that forms preferably has one to be given prominence to, should be outstanding with corner structure 100 and flange ledge 80 and 81 between the space of formation corresponding, therefore this fixed pivot 101 securely is assembled in the space that forms between corner structure 100 and flange ledge 80 and 81, thereby prevents that corner structure is mobile between the flange ledge. At first this angle mechanism 100 is in the basal surface of hull and its bottom surface 1 or intersect next door 2 and be connected, and next utilizes fixed pivot 101 to append to inward flange outstanding 80 and 81.

As shown in figure 13, an anchorage seat of anchor structure flat board 110 is used for fixing planar structures 200 of installing continuously from corner structure 100, and this anchorage seat flat board 110 is fixed on the surface in bottom surface 1 and intersection next door 2 equally at certain intervals. So far, certain interval forms one group of stud pin 109 on the inner surface of hull. At this moment, the part of this stud pin 109 and bottom surface 1 and intersect 2 in next door and contact, and by sharpening and extruding, thereby this stud pin 109 is welded on the inner surface of hull.

Then, anchorage seat flat board 110 has through hole corresponding to stud pin 109, thereby this stud pin 109 can assemble by these through holes and is assembled on the anchorage seat flat board 110. At this moment, this anchorage seat dull and stereotyped 110 is connected (for example welding or bonding) to the inner surface of hull. Further, lower dull and stereotyped 201 of the second insulation barrier of the thickness of anchorage seat flat board 110 and planar structure thickness is identical.

Then, as shown in figure 14, dull and stereotyped 111 connect with the upper surface of anchorage seat flat board 110 under the anchor, thus under this anchor dull and stereotyped 111 can the overlay planes structure the second insulation barrier lower dull and stereotyped 201. So far, under anchor on dull and stereotyped 111 the position of corresponding stud pin 109 form a plurality of through holes. Then, dull and stereotyped 110 usefulness, one nut of anchorage seat is completely fixed on the stud pin 109, and wherein this stud pin 109 runs through flat board 111 under the anchor.

So, planar structure 200 is only limited to and moves up, because flat board 111 is fixing under lower dull and stereotyped 201 usefulness fixed pivots 101 or the anchor, but can slide a little in the horizontal direction.

Then, shown in Figure 14 and 15, an anchor support bar 112 is vertically fixed on the center of flat board 111 under the anchor.

To last, under anchor dull and stereotyped 111 in be formed centrally a predetermined recessed space. Further, anchorage seat flat board 110 is positioned at the below of flat board 111 under the anchor. At this moment, anchorage seat flat board 110 has a plurality of and stud pin 109 corresponding through holes, and stud pin 109 passes through hole. Then, by fastening nut anchorage seat flat board 110 is fixed to stud pin 109.

One bar support cap 120 is installed in the recess of flat board 111 under the anchor by a centre bore of anchorage seat flat board 110. Bar support cap 120 is arranged to comprise or the whole nut that forms. In the present invention, this bar support cap 120 has a nut shape part at the center, and aforementioned anchor support bar 112 vertically is connected to bar support cap 120. Here, the mode of the bar support cap 61 among this bar support cap 120 and nut and Fig. 8 and hold-down nut 62 is the same.

Further, heat may be transmitted up or down by anchor support bar 112, but when being preferably in design anchor support bar 112, considers its diameter and pyroconductivity, drops to minimum thereby the liquefied gas from storage tank can be conducted to the heat of hull.

This anchor support bar 112 at first supports the load that the first sealing barrier produces, and this load will add in next process. Directly connect with pre-constructed unit and first sealing barrier of adhesive with insulation barrier, but this connection is not strong. Therefore, different from traditional insulation barrier parts, this pre-constructed unit can slightly slide with respect to the first sealing barrier, and the stability of tank structure resistance to deformation has also improved.

Each planar structure 200 places its position and fixing with respect to flat board 111 under the anchor of the present invention and anchor support bar 112 such as above-mentioned same fixed form. At this moment, each planar structure 200 places by the particular space on the dull and stereotyped 111 hull inner surfaces 1 of determining under the anchor, and fixing.

Above-mentioned planar structure 200 outside hull, finish prefabricated after, reinstall hull. One upper flat plate 205 connects with the upper surface of the first insulation barrier 204 of planar structure 200.

In other words, in planar structure 200 of the present invention, lower dull and stereotyped 201 of the second insulation barrier contacts with 1 of the inner surface of hull; The second insulating materials that polyurethane foam is made and the upper surface of lower flat board connect; The second sealing barrier 203 of being made by aluminium sheet or pliable and tough thin plate (flexible sheet) (three-ply board triplex) connects with the upper surface of the second insulation barrier again; Then, the upper surface of the first insulation barrier 204 of making of polyurethane foam and the second sealing barrier connects; And the upper flat plate 205 made of many plywood connects with the upper surface of the first insulation barrier again.

second insulation barriers

202 and 204, thereby, in next process, they can reciprocal interlockings and are fixed to adjacent plane structure 200 or the second sealing barrier of corner structure 100. The opposite flange side of planar structure contacts with corner structure 100, and is configured to the shape of Partial Resection, thereby can make and fix with anchor structure 150 of the present invention. Planar structure 200 of the present invention has the height same with adjacent angular structure 100.

Prefabricated planar structure 200 of the present invention is fixed on the inner surface of hull, its lower side of dull and stereotyped 201 is outstanding from the side of the second insulation barrier 202 of the planar structure on corner structure (not shown) opposite, and be inserted in the gap between the side of hull inner surface and fixed pivot, wherein to be used for that corner structure is fixed to flange outstanding for this fixed pivot; And lower dull and stereotyped 201 opposite side of this prefabricated planar structure 200 is outstanding from the another side of the second insulation barrier 202 of planar structure, and be inserted into simultaneously under anchorage seat dull and stereotyped 110 and the anchor in the gap between the flat board 111, wherein, this anchorage seat flat board 110 is fixed on the hull inner surface 1, and be made of metal, and flat board 111 is fixed on the upper surface of anchorage seat flat board under this anchor, and is made by many plywood.

As above-mentioned, if planar structure 200 inserted and fixing with respect to anchorage seat dull and stereotyped 111 and the anchor support bar 112 of anchor structure of the present invention, one second insulation barrier 113 of anchor structure places under the anchor on dull and stereotyped 111 as shown in figure 15. And then one second sealing barrier 114 has all waveform portion, and places on the upper surface of the second insulation barrier 113 of anchor structure. And, the second sealing barrier 114 is assembled to one in the fixedly step 121 that anchor support bar 112 forms, and by its support, then with hold-down nut these the second sealing barrier 114 bolts is connected to support bar 112, thereby is fixed.

Shown in Figure 15 to 22, if planar structure 200 places and fixing, the insulating materials made from polyurethane foam fills up the second insulation barrier 53 and 202 spaces that form by corner structure 100 and planar structure 200, and fills up the second insulation barrier 113 and second sealing barrier 114 of anchor structure around anchor support bar 112.

The second insulation barrier 113 of anchor structure is the hexahedron type, and the flat board that the insulating materials of being made by polyurethane foam and many plywood are made forms. The second sealing barrier 114 of anchor structure additional and that be fixed to the upper surface of the second insulation barrier is made by aluminium sheet or pliable and tough thin plate (flexible sheet) (three-ply board triplex).

In the steamer of LNG tank was installed, the hull that causes owing to the reason of wave etc. was crooked, and the mechanical stress a when part is navigated by water with ship is relevant. And then if therefore distortion of hull, the stress on insulation barrier and the second sealing barrier increases. Therefore, in order to reduce the mechanical stress on the sealing barrier, preferably as shown in figure 23, around the second sealing barrier 114, form waveform 115. That is to say and since when planar structure 200 when the hull inner surface slides, waveform portion 115 stretches or shrinks along glide direction, is difficult for generation mechanically deform or thermal deformation on insulation barrier or the sealing barrier.

And then the gap between each planar structure 200 is because the mechanical stress on the insulation barrier layer has the trend of increase. Be fixed on according to the planar structure 200 of storage tank of the present invention under the anchor of anchor structure 150 dull and stereotyped 111, yet this planar structure 200 can be slided on the inner surface of hull a little, removes and need not under the anchor flat board.

For above-mentioned reasons, self can absorb the distortion of hull this insulation barrier, because corner structure 100 is fixed in hull, but each planar structure 200 can partly slide at a longitudinal direction, even produce stress at hull.

As above-mentioned, after corner structure 100 of the present invention had been installed to the inner surface of hull with each planar structure 200, the insulating materials 211 made from polyurethane foam filled up the gap that forms between their second insulation barriers separately. Then, with fixing means the second adjacent separately insulation barrier is interconnected and fixes.

In other words, the second sealing barrier 52 of corner structure 100 is fixed to the sealing barrier 203 of adjacent plane structure 200, the second sealing barrier 203 of two adjacent plane structures 200 is interfixed, and the second sealing barrier 114 that the second sealing barrier 203 of planar structure 200 is fixed to anchor structure.

And then the insulating materials 210 made from polyurethane foam fills up the space that forms between the first insulation barrier separately.

Then, the first sealing barrier 250 is attached on the package assembly. The first sealing barrier welding (preferably fillet welded) to anchor structure, preferably is welded to the upper cap 119 of anchor structure. To elaborate the first sealing barrier hereinafter.

Figure 24 shows according to an embodiment of the invention a part of amplification view of the method for its second sealing barrier of interlocking of LNG tank, and Figure 25 shows according to an embodiment of the invention a part of enlarged perspective of the method for its second sealing barrier of interlocking of LNG tank, and then Figure 26 is a whole amplification view of setting forth the annexation between the corner structure that is installed in according to an embodiment of the invention the LNG tank in the steamer.

Connect and fixing the second sealing barrier of the present invention with fixing means in being connected with Figure 24. Such fixing means can be applied to all second sealing barriers of the present invention.

That is to say, as an example, as shown in figure 24, lower fixed flat planar 213 and upper fixed flat planar 212 place near the

second sealing barrier

52 and 203 mutual adjacent positions, thereby the second sealing barrier inserts between upper flat plate and the lower flat board, wherein this

second sealing barrier

52 and 203 be projected into respectively by first, second insulation barrier 57 of corner structure and 58 and the space (for example, the space between the insulation barrier) that forms of first,

second insulation barrier

204 and 202 of planar structure in. At this moment, by make with a hold-down nut 214 lower dull and stereotyped 213 and upper flat plate 212 mutually clamp, thereby fixedly secure the

second sealing barrier

52 and 203, although be not limited to this. Here, lower dull and stereotyped 213 and upper flat plate 212 be made of metal.

And then, lower dull and stereotyped 213 and upper flat plate 212 interconnects the

second sealing barrier

52 and 203 and fixing, and produce crooked. This can by make lower dull and stereotyped 213 and upper flat plate 212 mutually be clamped in correspondence with each other crooked recess in the face of part. Since the far-end of the second sealing barrier as above-mentioned be crooked, the sealing of the second sealing barrier has improved, and can prevent that any liquefied natural gas from revealing by the first sealing barrier.

In addition, lower dull and stereotyped 213 and the assembly of upper flat plate 212 to be preferably in a y direction slightly crooked, thereby have an extra length. Therefore, even this assembly shrinks owing to storage tank is full of the liquefied natural gas drop in temperature, this assembly can easily absorb owing to it shrinks the stress that produces, and further overcomes because the load that heat/Mechanical Contraction and extension produce.

And then because no matter the second sealing barrier is insulation barrier with another, or hull connects, and insulation barrier has certain free degree, therefore, can prevent from damaging insulation barrier owing to the hull inner surface is out of shape.

As above-mentioned, fill up insulating materials in the lower room that corner structure 100 box planar structures 200 form, and the second sealing barrier interfixes with aforementioned fixing means. Then, a nut and a packing ring in that the lower end set forms fill up fur, and are fixed to anchor support bar 112 around it. At this moment, this nut collar keeps the state that insulating materials pushed away with a predetermined pressure downwards. Here, in the storage tank of steamer that liquefied natural gas is packed into after, the amount of insulating materials, thickness for example availablely reduces by the pressure that increases liquefied natural gas. Therefore, this nut should be considered aforesaid minimizing insulation thickness in design.

Then, equally anchor insulation dull and stereotyped 118 is fixed on the first anchor insulation barrier 116, and doughnut upper end cap 119 further is inserted and secured on the end of anchor. So far, the first anchor insulate dull and stereotyped 118 upper surfaces in be formed centrally a predetermined recessed space, and in 119 of anchor upper end cap and this recess. Because this anchor upper end cap 119 comprises a nut or forms integral body with a nut structure, can be easily fixed in the upper end of anchor support bar 112. Therefore, the assembling of anchor structure 150 is finished.

Figure 26 is a whole amplification view of setting forth the annexation between the corner structure that is installed in according to an embodiment of the invention the LNG tank in the steamer. Anchor structure of the present invention 150 by a series of process manufacturings has same as shown in figure 26 connection.
