The specific embodiment
Below, with reference to the accompanying drawings of embodiments of the present invention.
1. the structure of side wall element
Fig. 1 illustrates an example of using the high-capacity liquid storage tank that the side wall element of an embodiment of the invention is assembled into.Side wall element has bonded structure at circumferential both ends, and bonded structure comprises circumferential faying flange.With regard to liquid storage tank, by being situated between, by circumferential faying flange, mutually combine junction structure each other, thereby along circumferentially connecting multiple side wall element, and by being layered on the independent diapire of manufacturing along short transverse connected the multiple cartridges that form by multiple side wall element, assemble thus.It should be noted that, in this manual, " cartridge " is not limited to the parts of rounded cylindrical body, can also comprise the parts of polygon cylindrical body.For the quantity of used side wall element and the quantity of cartridge, do not limit, can suitably select according to the size of liquid storage tank and purposes.Side wall element of the present invention is preferably used in capacity at least than 1000m
3large high-capacity liquid storage tank, even if be used in, for example internal diameter 12m is above, height 10m is above, capacity 1200m
3above liquid storage tank, also can prevent that liquid from leaking from the junction surface between side wall element reliably.
Side wall element of the present invention is manufactured by the Fabrication procedure that comprises the operation of eliminating the thermal deformation that welds the bonded structure producing, owing to thering is this eliminating deformation operation, even if therefore can obtain to apply in liquid storage tank in height, press, also can prevent from the side wall element of the bonding part leakage liquid between adjacent side wall element.And, the bonded structure of side wall element of the present invention has the special structure as having been described in detail below, by this structure, in the situation that having applied high interior pressure, also can keep the angle between circumferential faying flange and substrate parts, thereby can prevent the distortion of bonded structure.In addition, according to this structure, the joint portion between bonded structure and sidewall paneling can not deform, and therefore not only in a short time, in the situation that having applied high interior pressure for a long time, the leakage preventing effectiveness of liquid is also extremely remarkable.With regard to high-capacity liquid storage tank, especially the interior pressure that is applied to sidewall below tank becomes extremely large, therefore the thermal deformation when not considering to eliminate the manufacture of the bonding part between unit, and do not have in the existing unit of the such special structure of bonded structure of the present invention, cannot prevent reliably that liquid from leaking from bonding part.
Used the liquid storage tank of side wall element to mainly contain two kinds of forms below, side wall element of the present invention can be in the liquid storage tank of any one form of comprising these forms.One in two kinds of forms as shown in Figure 1, is the liquid storage tank 1 of cartridge cascade type.By the peripheral edge portion of the sidewall paneling of growing at lateral length (this be, the minor face of sidewall paneling) each multiple side wall element 10 that bonded structure is installed along circumferentially engaging and make cartridges 2, on diapire, along the stacked multiple cartridges 2 of short transverse, make the plurality of cartridge 2 become the structure of sidewall.Low below the inner pressure ratio applying above liquid storage tank 1, therefore adopt in the situation of this form, in the cartridge 2 of the sidewall above forming, need not use side wall element 10 of the present invention.That is, side wall element of the present invention can be used as to the unit of the below that is positioned at liquid storage tank 1, the unit of prior art be used as to the unit that is positioned at top.
The second form as shown in Figure 2, be single cartridge type liquid storage tank 1 '.By the peripheral edge portion of the sidewall paneling of growing at longitudinal length (this be, the long limit of sidewall paneling) each multiple side wall element 10 ' edge that bonded structure is installed circumferentially engage, on diapire, make cartridge 2 ', make this cartridge become liquid storage tank 1 ' the structure of sidewall.Adopt in the situation of this form, need to use side wall element of the present invention to all unit.
Here, take the liquid storage tank 1 of the cascade type shown in Fig. 1 as example, the structure of the side wall element 10 of an embodiment of the invention is described.Fig. 3 represents the side wall element 10 of an embodiment of the invention.Side wall element 10 comprises sidewall paneling 12 and is arranged on each two bonded structures 22,24 of opposed two peripheral edge portion 14,16 of sidewall paneling 12.In the following description, as shown in Figure 1, example explanation the present invention that the side wall element of being grown by four lateral lengths based on a cartridge 2 forms.
[bonded structure]
Fig. 4 A represents the bonded structure 22 of the peripheral edge portion 14 that is installed in sidewall paneling 12.At this, because bonded structure 24 also has the structure identical with bonded structure 22 conventionally, therefore only for the structure of bonded structure 22, be elaborated below.Bonded structure 22 has substrate parts 26, circumferential faying flange 28, multiple reinforcement feature 30.In Fig. 4 A, also show the sidewall paneling 12 that is arranged on bonded structure.
Substrate parts 26 and circumferentially faying flange 28 are to be circumferentially combined according to the mode of predetermined angular cross with a side 26A of substrate parts 26 with non-flange surface 28A flange surface 28B opposition side in conjunction with flange 28.This predetermined angle is the angle definite according to the diameter of liquid storage tank 1, is preferably 90 degree or is greater than 90 degree.That is, in liquid storage tank 1, the first type surface of substrate parts 26 (that is, face 26A) is along the wall configuration of tubular tank 1, and on the other hand, circumferentially the flange surface 28B of faying flange 28 need to be with respect to the wall arranged perpendicular of liquid storage tank 1.Therefore, circumferentially the intersecting angle between the non-flange surface 28A of faying flange 28 and the face 26A of a side of substrate parts 26 becomes 90 degree or is greater than the angle of 90 degree.The diameter of the liquid storage tank 1 of assembling is larger, can make this angle more approach 90 degree, and diameter is less, can make this angle larger.Circumferentially the position relationship between the long limit 28L of faying flange 28 and the long limit 26L of substrate parts 26, can be arranged in fact parallel.In Fig. 4 A, although the mode of holding up from the short side direction end of the non-flange surface 28A of circumferential faying flange 28 with substrate parts 26 illustrates, but also can make substrate parts 26 from the position beyond the end of the non-flange surface 28A of circumferential faying flange 28, for example, near the central authorities of short side direction, hold up.In this case, as shown in Figure 4 B, the circumferential faying flange 28 of side wall element 10 becomes the form of the inner side that enters into liquid storage tank 1, in the part of this inner side, also can use for example machanical fastener to engage adjacent circumferential faying flange 28, thereby further improve the bond strength between adjacent circumferential faying flange, can obtain the effect that better prevents leak of liquid.
And, in Fig. 4 A, although the mode of holding up from non-flange surface 28A with substrate parts 26 illustrate, also can make circumferential faying flange 28 hold up from the short side direction end of the face 26A of a side of substrate parts 26.But, when being configured to this structure, on face of joint when bonded structure 22 engages with other bonded structure, need to carry out circumferential faying flange 28 and the weld zone of the bound fraction of substrate parts 26 to carry out smear metal processing and make this faying face become smooth operation, therefore not only cause process number quantitative change many, and carry out the result of this operation, may cause producing ladder between the flange surface 28B of circumferential faying flange 28 and the end face of the long limit 26L of substrate parts 26 poor.In this case, exist and cause from the hidden danger of the face of joint leakage liquid between the adjacent structure of bonded structure 22, therefore need to guarantee fully the precision of planarization.
The mode that the interior angle side that multiple reinforcement features 30 form at the face 26A of the side by non-flange surface 28A and substrate parts 26 is holded up with the interval of being scheduled to mutually, is combined respectively each at least a portion of adjacent two edge part 30A, 30B with face 26A and the non-flange surface 28A of a side of substrate parts 26.
[sidewall paneling]
Can make sidewall paneling 12 for rectangular metal sheet, wherein, opposed two peripheral edge portion the 14, the 16th, minor face, opposed two short transverse edge parts the 18, the 20th, long limit.Sidewall paneling 12 is according to being housed inside the class of liquids of liquid storage tank 1 inside and the tenure of use of liquid storage tank, can by iron, corrosion-resistant steel etc. arbitrarily material make.The shape of sidewall paneling 12 is according to the shape of liquid storage tank 1 and form the quantity of side wall element 10 of a cartridge 2, can be configured to rectangle that lateral length grows, rectangle that longitudinal length is grown or foursquare any one.Thickness, the length of peripheral edge portion 14,16 and the length of short transverse edge part 18,20 for sidewall paneling 12 do not limit, and can, according to the size of liquid storage tank 1, suitably select.Sidewall paneling 12 can be before bonded structure being arranged on to peripheral edge portion 14,16 random time point, coordinate liquid storage tank 1 wall curvature and be bent.
[substrate parts]
The substrate parts 26 of present embodiment can consist of the metal plate-like body with two long limit 26L and two minor face 26S.Substrate parts 26 is according to being housed inside the class of liquids of liquid storage tank 1 inside and the tenure of use of liquid storage tank, can by iron, corrosion-resistant steel etc. arbitrarily material make.A side of long limit 26L is the edge part with peripheral edge portion 14 combinations of sidewall paneling 12 by welding, and therefore its length is preferably equal in length with peripheral edge portion 14.The length of minor face 26S is preferably and is configured to guarantee that the impact of the welding heat producing when soldered at substrate parts 26 and sidewall paneling 12 can not feed through to the distance of circumferential faying flange 28 described later.
Thickness to substrate parts 26 does not limit, and can suitably select according to the size of liquid storage tank 1.Substrate parts 26 be preferably be arranged to thicker than sidewall paneling 12.By the used thickness substrate parts 26 thicker than sidewall paneling 12, can more firmly keep the predetermined angular between substrate parts 26 and circumferential faying flange 28.As prior art, by sidewall paneling and the circumferential direct combination of faying flange in the situation that, when existence is subject to from the high pressure of inner liquid, cannot keep the angle between sidewall paneling and flange surface, opposed flange surface between adjacent unit struts from the direction that is equivalent to tank inner side, and the situation that causes internal liquid to leak.
[circumferentially faying flange]
Circumferentially on faying flange 28, through hole 32 can be set, such as to insert, for carrying out the fastener of mechanical engagement, the machanical fastener of nuts and bolt etc. with the circumferential faying flange 28 of adjacent side wall element 10.Through hole 32, can be as required arranges with interval arbitrarily without uniformly-spaced to arrange at the long side direction of circumferential faying flange 28.For example, in large capacity liquid storage tank, in side wall element 10, from the bonding part of short transverse, near the short transverse central authorities away from, be applied with the interior pressure that makes the distortion that side wall element 10 occurs to expand laterally.Therefore, in order further to improve the bond strength of circumferential faying flange 28 corresponding parts, as shown in Figure 4 C, interval between adjacent through hole 32 at the long side direction of circumferential faying flange 28 (, short transverse) from end, towards central portion, become narrower and narrower (that is, the quantity of through hole 32 becomes many).At this, in order further to improve the bond strength of circumferential faying flange 28, except changing the interval of through hole 32, or, can also change interval and make the diameter of through hole 32 become large, can insert the bolt that diameter is larger.The location optimization of the short side direction of through hole 32 is the position that as far as possible approaches substrate parts.
[reinforcement feature]
Each of multiple reinforcement features 30 can consist of metal plate-like body, as shown in Figure 4 A, can at least there is first side edge 30A on the face 26A of a side that a part is welded on substrate parts 26, the Second Edge edge 30B with respect to first side edge 30A with the angular cross of being scheduled at least a portion of being welded on non-flange surface 28A.Therefore,, according to first side edge 30A and Second Edge edge 30B, can keep the predetermined angle between substrate parts 26 and circumferential faying flange 28.As mentioned above, this predetermined angle is to carry out definite angle according to the diameter of liquid storage tank 1.Length to first side edge 30A and Second Edge edge 30B does not limit.First side edge 30A is preferably has at least identical with the minor face 26S of substrate parts 26 length.In another embodiment, more preferably, first side edge 30A is longer than the minor face 26S of substrate parts 26, makes on its face 12A that is welded on sidewall paneling 12.By the length of first side edge 30A being arranged to extend to from the face 26A of a side of substrate parts 26 the face 12A of sidewall paneling 12, thereby the joint portion between substrate parts 26 and sidewall paneling 12 can be out of shape because of interior pressure, and can strengthen the intensity with respect to the sidewall paneling 12 of interior pressure.
As shown in Fig. 5 (a), reinforcement feature 30 can further comprise opposed with first side edge 30A and have a 3rd edge part 30C, opposed with Second Edge edge 30B and be connected the 4th edge part 30D of one end of first side edge 30A and one end of the 3rd edge part 30C of the length corresponding with the minor face 26S of substrate parts 26.The length of the 3rd edge part 30C is preferably identical with the minor face 26S of substrate parts.Adopting this shape in the situation that the shape that reinforcement feature 30 is formed as the quadrangle that formed by first side edge 30A, Second Edge edge 30B and the 3rd edge part 30C and the part of being combined with the face 12A of sidewall paneling 12 in the 30A of first side edge and the 4th edge part 30D are combined as the triangle on adjacent both sides.By reinforcement feature 30 is formed as to this shape, tetragonal part plays substrate parts 26 and the circumferentially effect of the angle between faying flange 28 of keeping, leg-of-mutton part plays the effect of reinforced sidewall plate 12 with respect to the intensity of interior pressure, its result, in the higher large capacity liquid storage tank of interior pressure, also can prevent reliably that liquid from leaking from the bonding part between adjacent side wall element 10.
In multiple reinforcement features 30, as shown in Fig. 5 (b), more preferably, with first side edge 30A and Second Edge edge 30B between part corresponding to intersection point form notch 31.For there is no the reinforcement feature 30 of shape of notch 31, when bonded structure 22 is subject to interior pressure, stress concentrates on the intersection point place of first side edge 30A and Second Edge edge 30B, existence produces damaged possibility from this part, and by notch 31 is set, can prevent the generation of this problem.In addition, when there is no notch 31, substrate parts 26 and the circumferentially position that is welded on the intersection point between first side edge 30A and Second Edge edge 30B between faying flange 28 become discontinuous, and by forming notch 31, also have advantages of and both can be welded continuously.
In addition, in the present embodiment, as shown in Fig. 5 (a), it is poor that first side edge 30A is more preferably provided with ladder at middle part.In the present embodiment, the thickness of the Thickness Ratio sidewall paneling 12 of substrate parts 26 is thick, and as shown in Figure 4 A, because the mode that substrate parts 26 and sidewall paneling 12 are roughly positioned to same plane with the face 26B of the opposite side of substrate parts 26 and the inside face 12B of sidewall paneling 12 is combined, therefore between the face 26A of a side of substrate parts 26 and the outside face 12A of sidewall paneling 12, produce ladder poor, correspondingly, form reinforcement feature 30.Therefore, when the face 26A of the side for substrate parts 26 and the outside face 12A of sidewall paneling 12 are roughly positioned at the embodiment that the mode of same plane is combined, poor without ladder being set at first side edge 30A.And, in another embodiment, as shown in Fig. 5 (b), be more preferably equivalent to the poor part of ladder of first side edge 30A,, corresponding to the part of the binding site of sidewall paneling 12 and substrate parts 26, form notch 34.By forming notch 34, can obtain the following effect identical with the effect of notch 31: the stress that prevents the poor part of ladder is concentrated and prevents that the welding between sidewall paneling 12 and substrate parts 26 is discontinuous.
In the present embodiment, the interval of each of multiple reinforcement features 30 is identical, but is not limited to this, can be arranged to as required interval arbitrarily.In another embodiment, as shown in Figure 4 C, multiple reinforcement features 30 can be combined into compared with the interval with the end of the long side direction of circumferential faying flange 28, and near the interval central authorities of long side direction is narrower.By with this interval in conjunction with reinforcement feature 30, can more effectively resist near interior pressure suffered the short transverse central authorities of side wall element 10.
2. the manufacture method of side wall element
Then,, take the side wall element 10 shown in Fig. 3 as example, the manufacture method of side wall element of the present invention is described with reference to Fig. 6~Fig. 9.
[preparations of parts]
In the method, the parts of composition of preparation side wall element 10 first.
As mentioned above, side wall element 10 at least comprises a sidewall paneling 12, two bonded structures 22,24, and each of bonded structure 22 and 24 at least comprises a substrate parts 26, circumferential faying flange 28, multiple reinforcement feature 30.Quantity for reinforcement feature 30 does not limit, and the pressure that can bear according to the inwall of liquid storage tank 1 is suitably selected.The quantity that is used for the side wall element 10 of liquid storage tank 1 can suitably be selected according to the size of liquid storage tank 1, purposes or interior pressure etc., the parts of preparing in order to manufacture a liquid storage tank 1, that is, the quantity of sidewall paneling 12, substrate parts 26, circumferential faying flange 28 and reinforcement feature 30 changes according to the quantity of used side wall element 10.For example, as shown in Figure 1, when liquid storage tank 10 is used four cartridges 2 and forms, when a cartridge 2 is used four side wall element 10 to form, the quantity of the side wall element 10 of using is 16.
(1) first embodiment (not carrying out pre-assembled Fabrication procedure)
The manufacture method of the first embodiment of the present invention can comprise the first bonded structure and form operation, the first eliminating deformation operation, the second bonded structure formation operation, side wall element assembling procedure.In addition, can comprise as required the 3rd eliminating deformation operation and/or complementary eliminating deformation operation.The manufacture method of the first embodiment is different from the manufacture method of the second embodiment described later, does not carry out pre-assembled between bonded structure and forms bonded structure.
[the first bonded structure forms operation]
It is the operation that forms bonded structure 22 or 24 that the first bonded structure forms operation.Here, the bonded structure 22 shown in Fig. 4 A is described as the first bonded structure.In this operation, first, all parts is configured in to preposition, so that the end face of the side in two long limit 26L of the non-flange surface 28A of the face of a side contrary with the flange surface 28B of circumferential faying flange 28 and substrate parts 26 aligns.Now, the face 26A of a side of substrate parts 26 and non-flange surface 28A are configured in the mode of the angular cross of being scheduled to.And the interior angle side forming at the face 26A by a side and non-flange surface 28A is spaced from each other predetermined interval and configures multiple reinforcement features 30.Multiple reinforcement features 30 are preferably the first type surface that is configured to reinforcement feature 30 perpendicular to face 26A and face 28A.Can make position relationship between the long limit 28L of circumferential faying flange 28 and the long limit 26L of substrate parts 26 in fact parallel.
Then, between the long limit 26L and non-flange surface 28A of substrate parts 26, between at least a portion of the first side edge 30A of face 26A and reinforcement feature 30 and all combinations by welding between at least a portion of the Second Edge edge 30B of face 28A and reinforcement feature 30.Here said combination from the second embodiment described later, use in advance in conjunction with different, refer to when substrate parts 26, circumferentially faying flange 28 and multiple reinforcement feature 30 are assembled into liquid storage tank mutually, for the enough intensity of the tolerance of interior pressure, weld can guarantee.In this manual, this combination is called to formal combination.
Conventionally, in soldered part, when being cooled, weld zone produces the thermal contraction of material.Therefore, when face 26A mono-side of long limit 26L is welded with face 28A, for substrate parts 26 and circumferentially faying flange 28 act on and have the application force that makes the interior angle being formed by face 26A and face 28A be less than predetermined angle.But, in the present invention, by the reinforcement feature 30 that is predetermined angular in the angle of holding up in advance between face 26A and face 28A between first side edge 30A and Second Edge edge 30B, thus the contraction in the time of can resisting welding heat and be cooled, and keep the angle between these faces.
For the binding sequence between substrate parts 26, circumferentially faying flange 28 and multiple reinforcement feature 30, be not particularly limited.In one embodiment, the combination between substrate parts 26, circumferentially faying flange 28 and multiple reinforcement feature 30 is carried out in the following order: first, and each combination by circumferential faying flange 28 with multiple reinforcement features 30; Then, by circumferential faying flange 28 and substrate parts 26 combinations; Finally, by multiple reinforcement features and substrate parts 26 combinations.In another embodiment, the combination between substrate parts 26, circumferentially faying flange 28 and multiple reinforcement feature 30 can be carried out in the following order: first, and by substrate parts 26 and circumferentially faying flange 28 combinations; Then, by multiple reinforcement features 30 each with substrate parts 26 and circumferentially faying flange 28 be combined respectively.From reduce the viewpoint of the distortion being caused by welding heat as far as possible, the combination of substrate parts 26, circumferentially faying flange 28 and multiple reinforcement feature 30 is preferably according near the junction long side direction central authorities from circumferential faying flange 28 to be carried out towards the order of the junction of long side direction end.
[the first eliminating deformation operation]
In the manufacture method of side wall element of the present invention, the distortion that the most important thing is to eliminate bonded structure is pressed in the height of the liquid storage tank that has engaged side wall element can stand.For this reason, this method is characterised in that the operation that comprises the distortion of eliminating the bonded structure causing because of welding in the Fabrication procedure of side wall element.Fig. 6 represents the first eliminating deformation operation of the distortion of the bonded structure 22 for eliminating made.
The amount of contraction of the soldered parts that cause because of welding heat, welding capacity is more changeable must be larger.Therefore, bonded structure 22 is subject to the impact of the welding heat between welding and circumferential faying flange 28 and the multiple reinforcement feature 28 between substrate parts 26 and circumferential faying flange 28, during from the unilateral observation of the face 26A of a side of substrate parts 26, as shown in Figure 6 (a), with long limit (28L) the direction central portion of circumferential faying flange 28, to the side-prominent mode of non-flange surface 28A mono-, be out of shape.It should be noted that, for operation of the present invention is described, the overhang of having exaggerated is illustrated Fig. 6 (a), wishes this to be careful.Also identical for Fig. 7 described later (a).
Therefore, in the first eliminating deformation operation, for bonded structure 22, by the length direction both ends to bonded structure 22 and length direction central portion, apply the phase rightabout application force each other shown in the arrow of Fig. 6 (a), thereby can eliminate the distortion of bonded structure 22.The application force that can make to be applied to length direction central portion is the application force towards the direction of flange surface 28B from non-flange surface 28A, and the application force that makes to be applied to length direction both ends is the application force towards non-flange surface 28A direction from flange surface 28B.Specifically, the first eliminating deformation operation can realize according to following mode: the long side direction both ends that for example clamp the flange surface 28B of bonded structure 22 by clamping device, then for example use oil pressure hoisting crane etc., near the central authorities of the long limit 26L of substrate parts 26, apply the application force towards the direction of flange surface 28B.So, as shown in Figure 6 (b), can obtain that flange surface 28B is not out of shape, flange surface 28B accurately becomes the bonded structure 22 of plane.In fact this eliminating deformation operation cannot be eliminated after bonded structure 22 and sidewall paneling 12 are combined, therefore before bonded structure 22 and sidewall paneling 12 are combined, carries out.
At this, although shown in Figure 6, in the direction vertical with flange surface 28B with non-flange surface 28A, apply application force, the direction that applies application force is not limited to this.According to the situation of the distortion of bonded structure 22, the direction that sometimes for example has a suitable angle in the direction vertical with non-flange surface 28A and/or flange surface 28B applies application force.
[the 3rd eliminating deformation operation]
Fig. 7 represents the 3rd eliminating deformation operation of the distortion of other directions of the bonded structure 22 for eliminating made.As mentioned above, the contraction causing because of welding heat, during from the unilateral observation of the non-flange surface 28A of circumferential faying flange 28, as shown in Figure 7 (a), the situation that exists bonded structure 22 to be out of shape to one of circumferential faying flange 28 side-prominent mode with long limit (26L) the direction central portion of substrate parts 26.
Therefore, in the 3rd eliminating deformation operation, by the length direction both ends to bonded structure 22 and length direction central portion, apply the phase rightabout application force each other as shown in the arrow of Fig. 7 (a), thereby can eliminate the distortion of bonded structure 22.The application force that can make to be applied to length direction central portion is the application force towards the direction of the face 26B of the opposite side of the face of a side contrary with the face 26A of this side from the face 26A of a side of substrate parts 26, and the application force that makes to be applied to length direction both ends is the application force towards the face 26A of a side from the face 26B of opposite side.Specifically, the 3rd eliminating deformation operation can realize according to following mode: the long side direction both ends that for example clamp the another side 26B of the substrate parts 26 of bonded structure 22 by clamping device, then for example use oil pressure hoisting crane etc., near the central authorities of the circumferential long limit 28L of faying flange 28, apply the application force towards the direction of the face 26B of opposite side.So, as shown in Figure 7 (b) shows, can obtain that the face 26B of the opposite side of substrate parts 26 is not out of shape, the face 26B of opposite side accurately becomes the bonded structure 22 of plane.
In Fig. 7, although be illustrated in the direction vertical with the face 26A of a side of substrate parts 26 and the face 26B of opposite side, apply application force, the direction that applies application force is not limited to this.According to the situation of the distortion of bonded structure 22, the direction that sometimes for example has a suitable angle in the direction vertical with the face 26A of a side and/or the face 26B of opposite side applies application force.
At this, when only from prevent high-capacity liquid storage tank 1 leak of liquid viewpoint consider time, the 3rd eliminating deformation operation may not be carried out.That is, the leak of liquid of high-capacity liquid storage tank 1 does not conventionally accurately become plane and may occur at the flange surface 28B of circumferential faying flange 28.Therefore, as long as flange surface 28B becomes plane, even if bonded structure 22 is out of shape in the outstanding mode of the direction vertical with the face 26A of a side of substrate parts 26 or the face 26B of opposite side, this distortion can not become the problem that causes liquid to leak from high-capacity liquid storage tank 1 yet.Therefore, the 3rd eliminating deformation operation also can be omitted.
[the second bonded structure forms operation]
Then,, by the identical operation of the 3rd eliminating deformation operation that forms operation, the first eliminating deformation operation with the first above-mentioned bonded structure and carry out as required, form the second bonded structure.Here, using the bonded structure shown in Fig. 3 24 as the second bonded structure.
[bending operation of sidewall paneling]
According to the quantity of the side wall element 10 for the manufacture of liquid storage tank 1, make sidewall paneling 12 to become the mode bending of predetermined curvature.When for example for the liquid storage tank 1 of the cartridge cascade type shown in Fig. 1, can make sidewall paneling 12 become circular-arc mode bending to grow limit, when for example 1 ' time of liquid storage tank for the single cartridge type shown in Fig. 2, can make sidewall paneling 12 become circular-arc mode bending with minor face.The method of curved side wallboard 12 can adopt the method for well known to a person skilled in the art.
[side wall element assembling procedure]
Then,, in side wall element assembling procedure, sidewall paneling 12 and the first bonded structure 22 and the second bonded structure 24 can be carried out to combination.In side wall element assembling procedure, comprise following operation: by welding, one side 14 of the opposed peripheral edge portion of the sidewall paneling being bent 12 14,16 is combined with the long limit 26L of the substrate parts 26 of the first bonded structure 22, by welding, the opposite side of peripheral edge portion 16 is combined with the long limit 26L of the substrate parts 26 of the second bonded structure 24.From the viewpoint of the tolerance for interior pressure of liquid storage tank 1, consider, combination between peripheral edge portion 14,16 and the bonded structure 22,24 of sidewall paneling 12 is preferably, as mentioned above, the mode that according to the face 26B of the opposite side of substrate parts 26, roughly becomes same plane towards the face 12B of the inner side of liquid storage tank 1 towards the face of the inner side of liquid storage tank 1 in sidewall paneling 12 is combined.
[complementary eliminating deformation operation]
But, in side wall element of the present invention, the heat producing when the long limit 26L that the length of the minor face 26S of the substrate parts 26 of the bonded structure 22 shown in Fig. 4 A is preferably at the substrate parts 26 of welded joint structure 22 and the peripheral edge portion 14 of sidewall paneling 12 can not be delivered to the length of the degree of circumferential faying flange 28.Heat when this is because if welds is passed to circumferential faying flange 28, the hidden danger that exists the flange surface 28B of circumferential faying flange 28 to deform.But in fact, the heat in the time of sometimes cannot avoiding welding is delivered to circumferential faying flange 28, in this case, in the side wall element 10 after combining sidewall paneling 12 and bonded structure, circumferentially may residual deformation in faying flange 28.And, even in the case of not occurring distortion that the combination of sidewall paneling and bonded structure causes, also exist the distortion occurring in the operation before this combination to fail to be completely eliminated and remain in situation wherein.
In an embodiment of the invention, side wall element manufacture method can comprise the auxiliary eliminating deformation operation for eliminating these distortion.According to the deformation producing in bonded structure, this operation can be any one or two kinds in above-mentioned the first eliminating deformation operation and the 3rd eliminating deformation operation.
(2) second embodiments (carrying out pre-assembled Fabrication procedure)
The manufacture method of the second embodiment of the present invention can comprise the first eliminating deformation and the first bonded structure forms operation, the second bonded structure forms operation, side wall element assembling procedure.And, as required, can comprise the second eliminating deformation operation, the 3rd eliminating deformation operation and/or complementary eliminating deformation operation.In the manufacture method of the second embodiment, different from the manufacture method of the first embodiment, making substrate parts 26, circumferentially faying flange 28 and multiple reinforcement feature 30 intermediate of pre-combination each other, and to two intermediates carry out pre-assembled and make its restrained after, each parts is carried out in conjunction with (with respect to pre-combination, can be referred to as formal combination).By making the parts of intermediate soldered each other under the restrained state of two intermediates, and under this state, weld zone is cooled, thereby make the distortion that occurs when cooling suppressed because of residing restrained condition, result can be manufactured the bonded structure of having eliminated distortion.
[the first eliminating deformation and the first bonded structure form operation]
It is the operation that forms the first bonded structure when eliminating distortion that the first eliminating deformation and the first bonded structure form operation.Here, using the bonded structure 22 shown in Fig. 4 A as the first bonded structure, using the intermediate in operation as the first intermediate 22' and the second intermediate 22 ".Fig. 8 represents the first intermediate 22', and Fig. 9 represents the first intermediate body 22' and the second intermediate 22 " carries out pre-assembled and makes its restrained state.

3. manufacture liquid storage tank
Multiple side wall element 10 of using multiple side wall element 10 of manufacturing method according to the invention manufacture and/or having a structure of the present invention can be manufactured liquid storage tank 1.Liquid storage tank 1 shown in Fig. 1 can be manufactured by the following method: not shown at the diapire 3(preparing in addition) on stacked and engage the cartridge 2 forming along circumferentially engaging multiple side wall element 10, the cartridge 2 of the requirement that further sequential cascade forms in the same way on it is also engaged with each other it.In addition, the liquid storage tank 1' shown in Fig. 2 can be by not shown at the diapire 3'(preparing in addition) on along circumferentially engaging multiple side wall element 10', form cartridge 2' and manufacture.Although not diagram, can arrange corridor portion that people can walk about and for climbing the ladder of corridor portion on liquid storage tank 1 or 1'.This corridor portion can also be used as cripple when assembling liquid storage tank.The following describes the manufacture of the liquid storage tank 1 shown in Fig. 1.
In the case of using stacked and as liquid storage tank 1 along circumferentially engaging cartridge 2 that multiple side wall element 10 form, as shown in Figure 1, the location optimization of the bonded structure 22,24 of each side wall element 10 is stacked in the mode mutually staggering along short transverse on each cartridge 2.For example, as the liquid storage tank 1 of Fig. 1 in the situation that a cartridge 2 is used 4 side wall element 10, preferably, from the cartridge 2 of several the 2nd layer is with respect to from the cartridge 2 of several the 1st layer is stacked to rotate the state of 45 degree plane angles below below, the state that the cartridge 2 of the 3rd layer rotates 45 degree plane angles with respect to the cartridge 2 of the 2nd layer is stacked.The cartridge 2 of the cartridge 2 of the 4th layer with respect to the 3rd layer is also stacked by identical mode.So, by the bonding part with bonded structure, in short transverse, do not concentrate on the stacked cartridge 2 of mode of row, the liquid storage tank 1 of can being balanced property good structure.
[diapire]
Diapire 3 for liquid storage tank 1 is not particularly limited its structure, thickness, material etc., when for high-capacity liquid storage tank 1, as long as the suitably structure, thickness, material etc. of receiving fluids of state can not cause internal liquid to leak.In one embodiment, diapire 3 is preferably in advance the multiple unit that are manufactured into the pre-sizing that is applicable to carrying in fabrication shop etc., manufactured multiple unit to scene is set, are then used the machanical fasteners such as such as screw bolt and nut assembled by vehicle conveying.The most peripheral of diapire can have the junction surface for engaging with cartridge 2.
[machanical fastener]
In liquid storage tank 1, conventionally, the below of tank, the interior pressure being subject on wall is large.Therefore, the intensity engaging between adjacent bonded structure is preferably compared with the cartridge 2 with top, cartridge 2 one sides of below are larger.As the method that realizes this bond strength, mainly can adopt any one or two kinds in two kinds of methods below.Its one is, the cartridge 2 of below is more used the high mode of intensity of machanical fastener itself; Another kind is, the cartridge 2 of below, and the quantity of the machanical fastener using is more.
Adopt in the former situation, by the diameter chap of the bolt that makes to use as machanical fastener, thereby can improve bond strength.Therefore, in this case, the size that is arranged on the through hole 32 of the circumferential faying flange 28 of side wall element 10 is preferably and is used in liquid storage tank 1 below, and the size of through hole is larger.In addition, also can adopt the cartridge 2 of below, more use the mode of the fastener of the material that mechanical strength is high.
Adopt in the latter's situation, the quantity that is arranged on the through hole 32 of the circumferential faying flange 28 of side wall element 10 is preferably the below that is used in liquid storage tank 1, and quantity is more.In this case, along the stacked cartridge 2 of short transverse and manufacture liquid storage tank 1 in, preferably, below side wall element 10, make the quantity of reinforcement feature 30 more.
[sealing layer]
Opposed and when it is engaged with each other, preferably, between opposed flange surface 28B, be configured for the sealing layer that prevents inner leak of liquid at the flange surface 28B that makes the circumferential faying flange 28 in adjacent side wall element 10.For sealing layer, do not limit, but preferably use hydroexpansivity elastic sealing layer, at flange surface 28B, across through hole 32, be configured in corresponding to the region of tank inner side with corresponding to certain one or both sides in the region in tank outside.And, on flange surface 28B, across sealing layer and in the region corresponding to tank inner side with corresponding to certain one or both sides in the region in tank outside, can further configure other sealing layers of silicon sealing layer etc.
In order to obtain failure-free leak of liquid preventing effectiveness more, for example, as shown in figure 10, can be provided for configuring at the flange surface 28B of circumferential faying flange 28 groove 40 and/or 41 of sealing layer.By the internal configurations sealing layer at the groove 40,41 so arranging, thereby even if having adjacent circumferential faying flange 28 is strongly engaged each other, also can prevent the impaired advantage of sealing layer.If under the state that this groove 40,41 is not set and at flange surface 28B configuration sealing layer,, when circumferential faying flange 28 is strongly engaged, exist sealing layer damaged, reduce the situation of the effect that prevents leak of liquid.And, as another advantage, by being provided for configuring the groove 40,41 of sealing layer, thereby when assembling liquid storage tank, can obtain the effect of avoiding sealing layer dislocation and the effect of easily carrying out the aligned in position of adjacent circumferential faying flange 28.
[short transverse faying flange]
In the case of the liquid storage tank 1 by manufacturing along the stacked multiple cartridges 2 that multiple side wall element 10 are obtained along circumferential joint of short transverse, by the opposed short transverse end in each side wall element 10, short transverse faying flange is set, use for example machanical fastener to engage the opposed flange surface of adjacent short transverse faying flange, thus can be by stacked cartridge 2.Along the stacked cartridge of short transverse in the situation that, flange surface can be according to the deadweight of cartridge 2 and closure, and according to the deadweight of cartridge 2 and the closing force of closed flange surface much larger than hydraulic pressure, therefore short transverse faying flange is used the faying flange of common form of the prior art.For this faying flange, can, by the whole length range of the short transverse end of side wall element 10, with the tabular body of mode welded metal of vertically holding up from side wall element 10, form.
But, in order further to improve the bond strength of short transverse, as shown in figure 11, more preferably, can be also that the angle steel material (also referred to as mountain structural section) of L font is used as short transverse faying flange using cross sectional shape.Its reason be mainly following some.The first, the short transverse faying flange 50 being formed by angle steel material, the board 51 of one side with the gamut on opposed two the long limits of board 51 in be welded on side wall element 10.Therefore, (joint between short transverse faying flange 50 and side wall element 10 is divided into two places, the bound fraction of two long limits and unit), having can dispersive stress, and is difficult to the welding heat of short transverse faying flange 50 to be delivered to the advantage of flange itself.With respect to this, in side wall element 10, welded the short transverse faying flange of form of tabular body, because junction is positioned at a place or nearer place, therefore exist stress easily to concentrate, welding heat is passed to flange and may produces the problem of distortion.
The second, the short transverse faying flange 50 consisting of angle steel material, compared with the faying flange of tabular body, even if make the thickness attenuation of the board 52 of flange surface, also can keep same intensity.The short transverse faying flange 50 that this flange surface is thin, when using machanical fastener to engage opposed flange surface, more can improve close property.With respect to this, in the case of the faying flange of tabular body, because the thickness of flange surface becomes large, while therefore using machanical fastener to engage, be difficult to improve close property.
Although do not illustrate in Figure 11, the sealing layer that prevents leak of liquid be also preferably set on the flange surface 52 of short transverse faying flange 50.The detailed content of kind, collocation method and the position etc. of sealing layer is identical with the situation of circumferential faying flange 28.In addition, identical with the flange surface 28B of circumferential faying flange 28, on flange surface 52, also can be provided for configuring the groove of sealing layer.
