Insulated storage tank and method for installing its insulation structure - Isolerad förrädsbehällare och förfarande fter montering av dess isoleringskonstruktion

The invention relates to an insulated storage container of the type defined in the preamble of claim 1.

In this type of insulating structure known from AT-A-377 310, the insulating pieces are formed as elongate plates, in which at least one groove on the narrow longitudinal side and at least one connecting piece on the second narrow longitudinal side form in the shape of an arc of a circle; in this case, the length of the arc of the cross-section of the groove is greater than the arc of the semicircle and the length of the arc of the connecting piece is even greater than that of the cross-section of the groove.

For this reason, tightening ties have been required outside the insulation structure, which has meant additional material and considerable labor costs.

The invention is based on the object of providing an insulating structure which has both good thermal insulation capacity and which also reliably withstands high air forces due to wind pressure in large warehouses placed in an open place.

This object is solved by the features defined in the characterizing part of claim 1. By arranging the connecting and / or reinforcing parts in the area of the side edges, the reinforcing structure included in the insulation is provided when the boards are insulated. An insulating structure provided with such a reinforcing sphere structure is able to withstand external influences considerably better, whereby the insulating structure formed in this way can also be used in the presence of high wind speeds and the resulting suction forces. By reinforcing the boards from the area of the side edges, a denser insulating effect against moisture penetrating from the outside is achieved at the same time, whereby the thermal insulating effect of the insulating structure can be maintained for a long time. In addition, the panels are more durable due to the integrated reinforcements and transport and handling on site, and the loss due to plate breakage can be kept to a minimum.

Another embodiment is defined in claim 3. By using clamping devices arranged in the joint and / or reinforcement parts, in particular longitudinal and / or transverse clamping parts, the loads acting on the insulation can always be distributed over several plates, so that the parts required for reinforcement in the insulation can be dimensioned weaker than if each individual plate should receive the full load.

The embodiment of claim 4 is also advantageous because it can be used to provide internal force conduction inside the plate.

However, the embodiment according to claim 5 is also possible, whereby a good distribution is obtained between the traction forces on the gripping side of the wind and the suction forces on the opposite side of the wind.

However, the embodiment according to claim 6 is also advantageous, because it also allows the plates to be supported in their regions between the transverse tensioning parts in a precise position with respect to the storage container.

However, the embodiment according to claim 7 is also possible, in which case an additional support network can be provided in the reinforcement structure formed by the connecting and / or reinforcing parts integrated in the plates with longitudinal and transverse tensioning parts, by means of which the forces acting on the plates can be evenly distributed.

tt 3 93054

A further embodiment is described in claim 8. This embodiment makes it possible to join the plates arranged next to each other quickly. In addition, the transverse and / or longitudinal tightening parts arranged on each plate achieve a simple handling thereof, whereby the use of coupling parts at opposite ends of the transverse and / or longitudinal parts ensures a good transfer of force to the adjacent plates.

However, the embodiment according to claim 9 is also advantageous because it is accessible with one transverse clamping part around the entire circumference of the storage container, and the weight caused by several coupling devices distributed around the circumference of the storage container can be avoided.

Claim 10 discloses another preferred embodiment, in which the coupling parts of the coupling device arranged together only need to be fastened to one another, and when the insulating structure is completed, a fastening ring extending around the entire storage tank is obtained.

However, the construction according to claim 11 is also possible. It can be used to fasten adjacent transverse clamping parts in the middle area of the plate arranged in each case. In the case of plates installed as a "full seam", this also gives the possibility that, in addition to the end areas, the center of their length is provided with a transverse cross-section.

However, the embodiment according to claim 12 is also possible, in which the transverse tensioning parts necessary for fastening the plates are fixedly connected to them, so that they do not disappear at the construction site and do not need to be monitored or stored by additional parts.

The embodiment according to claim 13 is advantageous because it can apply forces considerably higher than 4 93054 to the individual plates than if the respective transverse tightening parts only traveled inside the plate. This larger surface, on which the plastic foam of the sheets can adhere, also provides a higher tear strength and thus also a better durability of the sheets.

The embodiment of claim 14 is preferred. It can avoid the cavities of the individual plates and thus the zones with a thinned cross-section. In addition, the sheets can be made thinner in wall thickness than in embodiments where the sheets are provided with cavities.

However, the insulating structure can also be formed in accordance with claim 15, in which case the transverse and longitudinal tightening parts can in each case be retrofitted to such transverse tightening parts.

Reinforcing the panels from the side edge area prevents flapping of their edges under high wind loads.

Claim 16 presents another solution, in which case the operation of the cross-tensioning parts cannot be adversely affected by the different temperatures acting on the storage container from the outside.

However, the embodiment according to claim 17 is also advantageous, since in this case a fastening ring can be integrated in the middle of the plates. With this reinforced spherical structure integrated in the plate and the reinforcement network formed by the transverse and longitudinal tensioning parts, the costs required for the plate supports can also be reduced.

However, the embodiment according to claim 18 is also advantageous because it can be retrofitted to the plate with a transverse or longitudinal tightening part.

11 5 93054

Claim 19 describes an embodiment that can provide fast and slip-tight tightening.

However, the embodiment according to claim 20 is also advantageous because this structure of the transverse tensioning parts does not require additional members for connecting them to the reinforcing parts of the plates.

Furthermore, the embodiment according to claim 21 is possible. By stepwise tightening the transverse tensioning parts, the individual sheets are stiffened relative to each other already during the installation of the insulating structure, which makes it easier to connect them to each other. In addition, the displacements of the plates possibly caused by the large tightening gaps during the tightening of the tightening part can be prevented.

Claim 22 discloses an embodiment for achieving simple joining of individual plates.

Claim 23 describes a preferred form of insulation structure. With this embodiment, it is possible to coat containers of different diameters with standard plates, whereby a good internal load-bearing connection between the tongues and the grooves achieves good load-bearing capacity for suction and pressure forces. Despite the possibility of fitting the plates to different outer diameters, a tight connection between the individual plates is achieved at the same time.

An embodiment according to claim 24 is also possible. Each plate then rests on two walls in the circumferential direction of the tank, spaced apart from each other, on the wall of the storage tank, and vibrations harmful to the insulating structure can thus be more easily damped.

The embodiment according to claim 25 is also advantageous because it reliably prevents the ingress of moisture, even at high wind pressures, from the seams or cracks.

6 93054

Claim 26 discloses an embodiment of an insulating structure which can reliably prevent the formation of condensation water and moisture between the outer wall of the storage tank and the inside of the insulating structure.

The embodiment according to claim 27 is also advantageous, because in addition to obtaining a precise connection to the individual sheets by using prefabricated profiles, the stiffness of the sheets also increases considerably in the area of their side edges, which makes the sheets more resistant to transport and installation and also makes the insulation structure more resistant to suction and compressive forces. against deformation.

The embodiment according to claim 28 is also advantageous because it achieves an internal connection between the profiles and the foam body of the sheets.

The embodiment according to claim 29 is also preferred. It can be used to reinforce the plates from the middle of their length.

Claim 30 describes an embodiment of an insulating structure which achieves relatively advantageous adjustability and thus a simple adaptation to the different outer diameters of the storage tanks.

The embodiment of claim 31 is also advantageous because the telescopic guide can form a tight connection between the profile parts.

An embodiment of an insulating structure is set out in claim 32. It achieves a tight connection between the individual plates, both inside and out.

Claim 33 shows an embodiment in which the joining of adjacent plates can be carried out without threading by pushing them nested in the circumferential direction in the direction of the longitudinal axis of the storage container.

In the embodiment according to claim 35, the reinforcing parts of the two adjacent plates can be connected by one mutually permeable connecting element.

Claim 36 describes an embodiment of an insulating structure. At the same time, the reinforcing parts provide protection against damage to the side edges during transport or installation.

Finally, the invention also includes a method of manufacturing an insulating structure.

This method is characterized by the attributes of claim 39. The step-by-step installation of the insulating structure and the clamping parts placed in it also makes it possible to install the insulating structure in several stages independently. In addition, by tightening the transverse clamping parts immediately following the interconnection, a fastening is achieved to the already installed parts of the insulating structure, which facilitates the installation of the following plates.

Other preferred embodiments are described in claims 34, 37 and 38.

In order that the invention may be better understood, it will now be described in more detail with reference to several embodiments shown in the drawings.

Figure 1 shows a storage tank 1, which has a cylindrical shape and can be used as a large tank for, for example, liquid substances, such as mineral oils, bitumen, or liquefied gases, such as liquid oxygen and nitrogen. The longitudinal axis 2 of the storage container 1 runs vertically with respect to its positioning surface 3. The storage tank can be made of steel sheet or concrete or the like, in order to thermally insulate the storage tank 1, its outside is surrounded by sheets 4 acting as insulating pieces.

The plates 4 are grooved with connecting and / or reinforcing parts in the region of their longer side edges 5.6 and in the region of their shorter side edges 7.8. The connecting and / or reinforcing parts in the region of the shorter side edges 7,8 are formed as nails 10 arranged in a mirror image on the surfaces 9 of the plate 9. The connecting and / or reinforcing parts in the region of the longer side edges 5,6 are formed as tongues 11 and grooves 12 which fit together nested. As will be described in more detail below, the cross-section of the tongue 11 has a longer arc length than the groove 12.

11 93054 with cutting. In this way, the plates can be placed in different angular positions relative to each other. In this way, similar sheets can be used for cladding storage tanks with different outer diameters.

As can be further seen from Fig. 1, in the circumferential direction, the adjacent plates 4 in the direction of the longitudinal axis 2 are in each case displaced by half a plate length relative to each other. This creates a "full seam joint". Such a high intrinsic strength is achieved for the cladding.

Figures 1-3 further show that a connecting and / or reinforcing part of the clamping device 14 is arranged at approximately equal distances from each of the two narrower side edges 7.8 of the plates. This tightening device 14 comprises a transverse or tightening part 15 embedded in the plate 4 in the flotation. As can be better seen in Figure 2, the transverse clamping part 15 is provided with openings through which the plastic material of the plate penetrates during foaming. The transverse cross-section is thus firmly anchored to the plate 4 and can receive high tensile forces.

The ends of the transverse tensioning part 15 are clamped to the coupling parts 16,17.

«

As further shown, the coupling portions 16, 17 of the two adjacent transverse tensioning portions 15 may be connected to each other, thereby forming a coupling device 18. The coupling device 18 may at the same time be formed as a tensioning element. However, it is also possible that the area of the threshold 19 adjacent to the nail is provided with a reinforcing part 34. In this case it is possible in each case to tighten the transverse tightening part 15 and connect it in the tightened state to the reinforcing part 20, for example with nails or screws. connecting the coupling parts 16 and 17 of the cross-tensioning part 15. In this way, a tighter and stronger fastening is achieved between the individual plates 4.

12 93054

Figure 3 shows a section 18 of the coupling device. The transverse clamping parts 15 adjacent to the coupling field part 16 are provided with cross ribs or teeth on opposite sides. The coupling part 17 is formed as a sleeve which surrounds each coupling part 16. The coupling parts 16, 17 are compressed by deformation of the coupling device 18 and fixed in their tightened position in their relative position. Of course, it is also possible to provide, for example, a sleeve-shaped coupling part 17 on the coupling part 16 side with transverse ribs, grooves or the like, so that in addition to frictional locking the transverse part 15 is also formed in its position in the coupling device 18. In addition, the plate 4 can made compatible. Thus, a nail 22 of approximately the same thickness is arranged on the extension 21 in the region of the side edge 7, but extends only to a part of the height 23 of the extension 21. This nail is associated with a recess 24 which provides free space for the transverse tensioning part 15 and the coupling device 18. a dimension 27, the extension 21 and the nail 22 of which overlap, smaller than the height 23 of the extension 21. The front edge of the extension 26 is provided with an approximately V-shaped groove 28 provided with a support threshold 29 in the region of the side edge 7 of the plate 4. compatible. The side surface 30 of this support threshold 29 is inclined towards the surface 9 of the plate, while the side surface 31 is inclined with respect to the plate surface 9 in the direction of the side edge 8. Due to the oblique of the side surface 30, the plates 4 can be placed together without play, because under the action of the oblique side surface 30 the side surface 32 of the nail 22 is pressed against the opposite side surface of the extension 21. Due to the oblique structure of the side surfaces 31, water or moisture penetrating into the gap between the side surface 13 93054 31 of the opposing groove 28 and the support threshold 29 can drain out and down. This further makes it difficult for moisture to penetrate the insulation structure without requiring expensive sealing arrangements. Of course, it is also possible to provide a further seal in the area of the side surface 31, in the form of a lip seal, for example, which closes any free space between the groove 28 and the support sill 29, or this void can be filled with plastic foam, or the side surface 30 of the support sill 29 and the opposite extension. An adhesive or sealant can be applied between the 26 side surfaces.

The use of the threshold 29 prevents the suction, in particular caused by the wind load of the storage tank 1, from detaching or bending the arranged side edges 7,8 apart, thus reducing the risk of the individual plates 4 coming off their joints due to vacuum or suction. .

Figures 4 to 6 show plates formed as insulating pieces placed outside the cylindrical wall 33 of the storage container 1 corresponding to Figure 1, parallel to the longitudinal axis • 2 or the base line of this cylinder. The longitudinal narrow side or side edge 6 of each plate 4 * has a groove 12 and the opposite longitudinal narrow side has a connecting stop, e.g. a tongue 11 (Fig. 5), whereby the tongue 11 and the groove 12 fit together. Seen from above, both the tongue 11 and the groove 12 have a circular arc-shaped profile, with the arc length of the groove 12 being greater than the semicircular arc and the arc length of the joint or tongue 11 being even greater than that of the groove cross-section, as detailed in Figure 17.

14 93054 In order to install such an insulating structure, the connecting stop or tongue 11 of the plate 4 is inserted into the groove 12 of the adjacent plate in their longitudinal direction, and the interconnected plates are placed around the wall of the storage tank 1, the insulating structure being half-finished.

As can still be seen in Figures 4 and 5, each plate 4 has three reinforcing members 34 transverse to its longitudinal direction, two of which are at the ends or side edges of the plate 7.8 and one in the middle of the plate 35. Since, as shown in Figure 4, the plates are arranged displaced with respect to each other by half a dimension, and thus forming a "full seam", the reinforcing parts 34 in the middle of the plate 35 always between the reinforcing parts at the plate ends of the adjacent set of plates; thus they form a closed annular structure in a horizontal plane around the cylindrical wall 33 of the large container 1.

As can be seen in Figure 5 and the enlarged view of Figure 6, each reinforcing member 34 in Figure 6 extends from its left end from the outer edge 36 delimited by the groove 12 to the connecting response formed by the tongue 11 to the outer edge 36 side of the adjacent plate 4. In this case, the screw 37 (Fig. 6) pierces the overlapping parts, i.e. the outer edge 36 and the tongue 11 of the adjacent plates and the ends of the reinforcement parts 34 embedded in them, whereby the reinforcements form a force-locked connection around the entire cylindrical container. The reinforcement of the plate sets 4 formed in this way provides a durable structure against strong suction and traction forces caused by wind pressure.

As described in connection with Figures 4 and 6, this design can be used in the insulating structure according to patent 377 310, but also in insulating structures in which the longitudinal narrow side profiling is not in the shape of a circular arc, as shown in Figures 93054. 7 and 8, where for the sake of simplicity it is assumed that the flat wall of the storage tank 1 is to be insulated.

In both cases, connecting and / or reinforcing parts 34 are used, which are arranged and recessed in substantially the same way as in Figures 4 and 6.

According to Fig. 7, the longitudinal narrow sides or side edges 5,6 of the plates 4 have a stepped profiling 38 so that in the left plate 4 of Fig. 7 the connecting and / or reinforcing parts 34 are outside the plate at their right end and at the other end, i.e. the right plate 4 reinforcement left end, they are located approximately in the middle of the plate so that their outside fills the butt gap along the longitudinal narrow sides of the plates 4.

According to Fig. 8, the profiling 38 between the plates 4 is formed as a kind of tongue-and-groove connection. Then, similarly to Fig. 7, in Fig. 8, the left end of the reinforcement portion 34 of the right plate 4 is outside the plate in the outer portion of the outer edge 36, and the other end, here the right end of the left plate reinforcement portion 34 of Fig. 8, is bonded to the outer surface 40 of the tongue.

The embodiments of Figures 7 and 8 can, of course, also be used in cylindrical containers with an outer wall 33 by arranging the plates 4 at obtuse angles to each other as in Figure 6.

Other modifications and constructions of the described insulating structure are also possible within the scope of the invention. Instead of screws 37, nails, rivets and the like can also be used as connecting parts. Laminated fittings, including plastics, can be used as the material for the reinforcements or reinforcement parts 20, 34. Wood laminates, especially plywood, have also proven to be suitable. Foamed or extruded plastic parts can also be used. In addition, it is possible to form the reinforcing parts from metal, e.g. aluminum, GRP or plastic, as over-pushed or at least partially embedded profile parts in the flotation.

In addition, it is advantageous if the outer sides of the plates 4, i.e. the sides on the other side of their storage container 1 relative to the wall, are provided with e.g. an aluminum cover layer.

In Figures 9 and 10, insulating pieces formed of plates 4 are arranged outside the cylindrical wall 33 of the large container with a longitudinal axis vertical, parallel to the base line of this cylindrical wall. Each plate 4, which on its outer surface may be provided with e.g. an aluminum cover layer, has a groove 12 in the narrow longitudinal side or side edge 5 and a connecting stop or tongue 11 in the narrow longitudinal side or side edge 6 opposite it (Fig. 10), whereby the connecting stop, i.e. the tongue, groove 12 fit together. Seen from above, each part, the tongue 11 and the groove 12, has a circular arc-shaped profile, the arc length of the groove 12 being greater than the arc of a semicircle, and the arc length of the joint stop even greater than the cross section of the groove 12, as detailed in Figure 17 and AT 377 310. Fig.

The plates 4 are then staggered, as can be seen in Fig. 9, with a central longitudinal displacement, i.e. they are "fully sealed"; the upper and lower edges of the plates are profiled; so that a step or nail 10 is formed in them.

In order to install such an insulating structure, the connecting stop or tongue 11 of the plate 4 is inserted into the groove 12 of the adjacent plate 4 in the longitudinal direction, and the interconnected plates 4 are placed around the tank wall 33, whereby the insulating structure is already half finished.

Il 17 93054

As can be further seen from Figure 10, each step or nail 10 of the plate 4 has a reinforcement against the deformation which is transverse to the longitudinal direction, e.g. a plywood reinforcement 34, which is only at the upper edge, as also shown in Figures 11-14. As shown in Fig. 15, in which the upwardly continuous plate 4 following the corresponding lower profiled edge part is shown by a dotted line, the upper half of the reinforcing part 34 is in front of the step or nail 10 and its lower half is embedded and well anchored in the foam body 4. Since, as can be seen in Fig. 9, the plates 4 are displaced longitudinally with respect to each other by the plate length, the steps or nails 10 and the reinforcing parts 34 always hit the center of the plate 4 next to the plate 41.

As can be seen from Fig. 16 together with Fig. 9, each plate has a hollow tube 42 in its center 35, which forms a reinforcing part 43. This is suitably a metal rectangular tube with e.g. a transverse tensioning part 44 formed of metal strip. Of course, a circular cross-section can also be used. in the area of the tube-a, U-profile or cavity 42 on the surface delimiting in the direction of the wall 33 only a plate-like reinforcing part. Suitable materials are wood, plastic and ferrous or non-ferrous metals. The length 45 of the transverse tension member 44 is somewhat greater than twice the width of the plate 4, 41, so that each metal strip of the plate 4 extends over the middle of the plate 41 adjacent to it.

In Figures 11 and 13, at the left end of the strip or transverse tension member 44, the remainder is widened as a coupling member 16 having a transverse tooth 47 transverse to the longitudinal direction of the strip and a longitudinal hole 48. Two holes 49 are formed from this tooth 47 to receive the center of the strip. of these two holes on the right shown in the anchoring,. 93054 screw 50. As can be seen in Fig. 15, the strip of the transverse tightening member 44 is located between the steps of the profiled edge portions of the upper and lower end portions of the plates 4. In this case, the sum of the thicknesses of the edges 54.55 is less than the thickness of the plates 4.

In the second, in Figures 12, 14, at the right end of the strip-shaped transverse clamping part 44, the end end is likewise widened as a coupling part 17, here with an external toothing 57. This coupling part 17 is also provided with holes 49 for anchoring screws 50. In addition, each (right) end or coupling part 17 of the strip is provided with a spaced hole 58 extending through the reinforcing part 34 of each plate 4 and enabling the use of a tensioning member 59, e.g. tensioning pliers, of the strip-shaped transverse tensioning part 44.

When installing boards 4 on top of each other, proceed as follows:

For example, when the top plate 4 of Figure 9 is inserted between two adjacent plates 41 from above, as described above, the end or engagement portions 16,17 of the strip of the transverse tensioning portion 44 protruding on both sides of the cavity 42 precisely center the adjacent plates 41 and their reinforcing portions. 34 forward. In this case, at least one anchoring screw 50 is screwed through the holes in the left end or coupling part 16 into the reinforcing part 34, whereby the left end part of the strip is firmly attached to the left plate 41. Tight pliers 59 are shown in thin dashed lines in Fig. 14. 58, and one jaw of which engages and tightens the right coupling portion 17 of the transverse tightening member 44, after which the right coupling portion is secured in the tightened state by at least one anchoring screw 50 19 93054 in the hole 49. The transverse tightening portion 44 of the plate 4 adjacent to the plate 41 (right) is then positioned. the teeth 47 and 57 engage in opposite engagement, the longitudinal hole 48 allowing dimensional tolerance adjustment of the plates 41, and then formed by a fixing screw 50, which may have self-cutting threads and which is inserted into the longitudinal hole The 48 into the underlying kytkentöosaan 17, permanent connection of the meshing engagement between adjacent 47.57 poi kittaiskiristysosien 44 of the coupling portions 16,17. When the installation of the plates 4 around the container, e.g. in rows or sectors, is completed in this way, the right coupling part 17 of the last transverse tightening part 44 is finally fastened to the left coupling part 16 of the first transverse tightening part 44 of the plate 4 permanently with self-tapping threads. the strips of transverse tension members 44 bonded together in a manner to form a stack. a closed ring-shaped reinforcing structure around the cylindrical wall 33 of the tank 1 which withstands the high demands of the wind forces present.

Within the scope of the invention, many modifications and constructions of the described embodiment are possible. Instead of plywood or wood laminate, other screwable materials can also be used as reinforcement parts, such as laminated composite pieces, also plastic. Hooks may also be used to join the strips or transverse tension members 15 together; in addition, shroud screws or ba-j connectors can be used here.

The cavities 42 need not be formed of or delimited by a tube; in many cases, a U-profile or plate can be used or omitted. The cavities 42 may also be formed as grooved recesses in the outer surface of the plates 4,41; the bottom of the groove is then similarly suitably provided with plywood or similar reinforcement. Such cavities need not be located in the center of the plate; they can also be placed in the thirds of the longitudinal narrow sides.

Figure 17 shows the outer wall 33 of the storage tank 1. An insulating structure consisting of plates 4 is arranged on this wall 3. These plates consist of foam pieces 61 and cover layers 62 preferably attached to them in the flotation procedure. Slots 12 and tongues 11 are used to connect the plates 4 from their side edges 5,6. connecting and / or reinforcing parts 63. In order for the plates 4 to be used for insulating storage tanks 1 of different diameters, the groove 12 has a circular arc-shaped cross-section. The cross-section of the tongue is similarly formed in the shape of an arc of a circle and resembles a cylindrical part. The diameters of the groove 12 and the tongue li are equal so that the plates fit together in a backlash-free manner. In order to be able to turn the plates 4 in the radial direction with respect to the storage container 1, the arc length 64 of the groove 12 is greater than the arc of the semicircle. The arc length 65 of the tongue 11 is greater than that of the cross section of the groove 12. By the difference of the arc lengths 64 and 65, the mutual turning range of the plates 4 can be adjusted. Thus, since the cross-sectional arc length of the groove 12 is greater than the arc of a semicircle, each possible relative pivoting position between the groove 12 and the tongue 11 provides a fixed connection between the groove 11 and the tongue 12.

Figure 18 shows another embodiment of the plate 66. ; The plate has a fold 67 and is formed in a V-shape.

The V-angle is only slightly less than 180 °. This ensures that the plate 66 rests at two points on the wall of the storage tank 1. In the region of the side edges 5.6, connecting and / or reinforcing parts 69 formed of profiles 68 are arranged. These can be, for example, extruded profiles.

The extruded profiles are attached to the foam body 61 by gluing or the foam bodies 61 are foamed into the profiles. The arc length 64 of the groove 12 is again greater than the arc of the semicircle and the arc length 65 of the tongue 11 is greater than the arc length 64. This achieves the same effect as described for the plates 66 of Figure 17. However, an additional connecting and / or reinforcing part 69 is formed in the plate 66, which consists of a transverse crossing part 70. Connecting and / or reinforcing parts 71, 72 are arranged in this connecting and / or reinforcing part 69. These connecting and / or reinforcing parts 71, 72 are flush-immersed in the foam body 61 and extend beyond the surface 33 on the wall 33 side of the storage container 1 of the plate 66 - as can be seen from the connecting and / or reinforcing parts 72 - or are arranged in recesses 73 in these surfaces. that the connecting and / or reinforcing portion 71 does not damage the wall 33 or the anti-corrosion layer added thereto or the like.

Fig. 19 shows an embodiment of the connecting and / or reinforcing part 74, in which they are arranged on the side edges 5 and 6 of the adjacent plates 4,41. The connecting and / or reinforcing parts 74 consist, for example, of profiles 75, 76 which are extruded plastic or aluminum. In the embodiment shown, these profiles 75.76 are formed as hollow: profiles with a high stability against deformation transverse to their length in relation to the axis, whereby the overall strength of the plates 4 and 41 is further increased. In addition, the plates 4.41 are thus strengthened in their transition area, so that even at high air forces a tight connection between the plates 4.41 is achieved. In order to fix the plates in their respective angular position depending on the diameter or radius of the storage tank 1, as shown by way of example in Fig. 19, the hollow space 77 can be foamed schematically with diagonal plastic foam 78 to against which a spacer 79, e.g. a wedge or the like, can be used on the side 33 of the wall 75.76 of the profiles. In addition, overlapping sealing lips 80 can be used in the area of the spacer 79, whereby by placing the sealing lips 80 tightly together, this intermediate space can also be foamed simultaneously. In order to secure the plastic foam 78 firmly in the hollow space 77, it is possible, as indicated by the broken line, to provide a fastening part 81 in the profile 75 or profile 76 so that the plastic foam can adhere to the empty space 77. In addition, it is also possible to fill the empty space 82,83 with plastic foam 78. uninterrupted insulation effect over the entire insulation structure also in the area between the plastic frames of the sheets 4.41. This can be done, for example, by arranging openings in the partitions between the plates 4.41 and the hollow spaces 82.93, as schematically shown.

Fig. 20 shows a modified embodiment of the profiles 75,76, in which the relative positions of the profiles are fastened to each other by a fastening strip 84. This fastening strip 84 can also be provided with threads, e.g. self-cutting threads, for fastening it to the profiles 75,76, e.g. To this end, the wall thicknesses of the profiles 75.76 have been reinforced - as schematically shown - so as to provide sufficient strength against the widening of the hole. As further schematically shown in broken lines, the mounting strip 84 may also penetrate the entire hollow space 83 of the profile 75 and penetrate the opposite side of the profiles 75 and 76; Ic. In this embodiment, it is of course also possible to fill the empty spaces 82 and 83 of the profiles 75, 76 marked with the same reference numerals with plastic foam and in addition to add plastic foam or a spacer to the hollow space.

One advantage of the design of the connecting and / or reinforcing part 74 shown is that the opposite telescopic control i 93054 achieves a perfect seal, in particular against the penetration of rainwater into the interior of the insulating structure.

Instead of the fastening strip 84 shown, other suitable fastening devices such as screws, spring bolts, hollow rivets and the like can, of course, also be used.

Figures 21-23 show another embodiment of an insulator according to the invention used in connection with individual plates 4. As already described in connection with Figures 1, 4 and 9, the adjacent rows running parallel to the longitudinal axis 2 of the container are in each case displaced relative to each other by the length 85 of the plates 4. In the embodiments of Figures 1-20, when the plates 4 and 41 were joined by side edge-long profile portions formed of tongues and grooves, the plates 4,41 in this embodiment are secured mainly by transverse clamping portions 86 and longitudinal clamping portions 87. Plates 4,41 are in the region of their side edges 5,6 provided with connecting and / or reinforcing parts 88 and 89, respectively. The connecting and / or reinforcing parts 88 are formed in half shells in the region of the opposite side edges 5.6 of the plates 4.41. A connecting and / or reinforcing part arranged in the region of the side edge 5; The inner diameter of the half-shell 88 corresponds substantially to the outer diameter 91 of the half-shell 91 of the connecting and / or reinforcing part 88 arranged on the side edge 6. The inner diameter 92 of the connecting and / or reinforcing part 88 connected to the side edge 6 substantially corresponds to the outer diameter 93 of the longitudinal tensioning part 87. flexible. pipe piece or the like. In particular, when the longitudinal tensioning part 87 is formed of a plastic or metal pipe, it can be fixed to the underground ground on the concrete base 94 and supported by the support piece 95 on the wall 33 of the storage tank 1. Of course, it is also possible to use a metal base or similar material instead of the concrete base 94. a support structure in which the lower end of the steel rope or tube forming the longitudinal tensioning portion 87 is anchored. The joining of the plates 4,41 to one of their opposite side edges 7,8 takes place, as will be better seen in Fig. 22, by a transverse tensioning part 86, which may be a strip, rope or the like running around the storage container 1. As shown in Fig. 22, the connecting and / or reinforcing parts 89 can then be used to form a locking response on the superimposed plates. For this purpose, a groove 96 is arranged in the area of the side edge 8, in which a support arc 97 arranged in the groove 96 in cross-sectional shape engages. Against this support arc of the connecting and / or reinforcing part 89 also rests the transverse clamping part 86 and influences the positioning of the plates 4 in the radial direction with respect to the storage container 1 or its wall 33. In this way, the flutter of the plates in the region of the side edges 7 and 8 facing each other, caused by strong storms in the region of the surface of the tank, can be relieved. The forces thus generated are received in the annular transverse tension member 86 and are evenly distributed in the joint and / or reinforcement portions 88,89 of the individual plates 4.41.

The connecting and / or reinforcing portions 88,89 are provided with anchoring portions 98 which extend inside the foam body of the plates 4 and 41 and are preferably embedded therein during foaming. However, it is also possible to provide the plates with recesses to which the connecting and / or reinforcing parts 88,89 can be attached by means of a castable resin or adhesive.

As best seen in Fig. 23, the transverse cross-section 86 extends when it is at the side edges 7.8 of the individual plates 4, 41 in the region of the groove 96, while in the central region of the plates it can pass between the plate 4 and the wall 33. The fastening between the transverse tensioning part 86 and the plate 4 can take place in the central area, e.g. as shown in Fig. 18. using joints and / or reinforcements 71.

il 25 9 3 0 5 4

However, as further shown in phantom in Fig. 22, it is also possible to provide the plates 4.41 in the central region with a recess 99, through which the transverse tensioning part 86 can be guided. Between the transverse tensioning part 86 and the surface of the recess 99 arranged thereon in the direction of the wall 33, a reinforcing part 34 can be placed in a manner similar to that described in connection with Figs. However, it is also possible to embed the transverse tensioning part 86 in connection with the flotation in the foam body of the plates 4.41 as described in connection with Figures 2 and 3. In the embodiments of Figures 1-20, when the support against opening of the plates in the vacuum created by the suction effect is formed exclusively by the transverse tensioning members, the suction forces acting on the plate surface are distributed in this embodiment to the longitudinal and transverse tensioning members 86 and 87. and thus fasten the side edges 7 or 8 running vertically through the longitudinal tightening parts 87 in this embodiment against relative movement in the suction direction. After or before the transverse tensioning members 87 are tightened, the longitudinal tensioning members 87 are also pulled or tightened so that the plates remain in the backlash without the longitudinal tensioning members 87 even in the area between the transverse tensioning members.

«

Slabs 4,41, the side edges of which are stiffened by connecting and / or reinforcing parts 88,89 and which have an additional reinforcing mesh formed by the longitudinal and transverse tightening parts, are installed as follows:. ' First, the longitudinal tensioning portions 87 are placed at intervals corresponding to the width 46 of the plates 4.41 and are pre-tensioned. A first row of plates is then placed between the longitudinal tensioning portions 87. The transverse clamping portions 86 are then installed in the region of the length center of the first row of plates and in the region of the ends. They are temporarily or permanently tightened to the desired tightness depending on whether the insulating structure is installed around the perimeter of the storage tank in one operation or in several adjacent areas. The next row of plates 4.41 is then joined between the longitudinal clamping parts 87, simultaneously installing the necessary transverse clamping parts 86. When the insulating structure is completed, the longitudinal clamping parts 86 are also tightened to a predetermined tightness so that the tightened longitudinal clamping part 87 or the reinforcing member 88 in the desired position.

In order also to achieve a corresponding seal between them in this embodiment, in which the foam pieces 61 do not directly overlap, a seal 100 can be placed in the transition area, as schematically shown.

Figures 24-26 show other different constructions of the tongues 11 and grooves 12 of the connecting and / or reinforcing parts 101,102, which are preferably arranged on the vertical side edges 5.6 of the plates 4.41. By means of these adjustable embodiments, the interconnected connecting and / or reinforcing parts 101,102 can, above all, be fastened to their respective angular positions relative to one another. For this purpose, the connecting and / or reinforcing part 101 formed as a tongue 11 is provided with a longitudinal groove 103. A corresponding longitudinal groove 104 is arranged on this longitudinal groove 103 in the region of the groove 12 of the connecting and / or reinforcing part 102. the smallest angular steps to lock them longitudinally; automatically to their respective positions.

In the embodiment of Fig. 25, the flat part 105 makes it easier to push the tongue 11 into the groove 12 in the extreme mutual angular position of the plate surfaces 9. By turning them to the operating position 27 93054 shown in Fig. 25, a full-surface fit between the spring 11 and the groove 12 is then obtained. In order to also ensure a form-fitting connection and / or locking of the connecting and / or reinforcing parts 101,102 in such a structure, a plastic space, e.g. a plastic foam 78, such as polyurethane or the like, can be foamed or molded into the empty space 106 between the flat part 105 and the groove 12. In this way, the tongue 11 and the groove 12 are connected to each other in a form-fitting manner, and it is no longer possible to change the position of the plates 4.41 after installation. This also prevents flaring in the region of the side edges 5.6 in the strong vacuum phenomena caused by the suction effect.

In Fig. 26, both the tongue 11 and the groove 12 are provided with a polygonal cross-section, whereby the number of angles of the groove 12 and the tongue 11 is the same, or the number of angles of the groove 12 may be a direct multiple of the number of angles of the tongue 11.

At the same time, the number of angles of the groove 12 determines the smallest adjustment angle at which the plates 4.41 can be changed relative to each other in their position. Also in this embodiment, the plates 4.41 automatically lock in place after adjustment. Correspondingly, by means of the structure of the plate part of the plate 4 adjacent to the resiliently grooving groove 12, the plates can be turned relative to each other without the tongue 11 having to be removed from the groove 12. To form a form-fitting connection between the plates 4,41. as shown by the dashed line. The void space between the flat portion 105 and the groove 12 can then be filled with plastic 78, as described in connection with Figure 25.

Within the scope of the invention, it is of course possible to use each of the described and described embodiments of the connecting and / or reinforcing part in connection with another, e.g. also described in connection with side edges 5,6 28 93054, at side edges 7,8 and vice versa and to connect them to one another. In the same way, it is possible to use the connecting and / or reinforcing part, regardless of its structure, in each of the desired embodiments of the transverse and / or longitudinal tightening parts described and explained. In the region of the tongues 11 and the grooves 12, it is also possible, for example, to use reinforcement parts 107, as shown by the colon line in Fig. 26. Reinforcement portions 108 can be placed in the area adjacent the groove 12 of the plate 4 or 41, whereby the reinforcing portions 107,108 of the plates 4,41 are fastened together by fastening screws 50 so that the self-supporting plate portions on both sides of the groove 12 engage the tongue 11 and prevent it from rising.

Figures 24-26 also show still other embodiments and arrangement possibilities for seals 109, 110, which are formed, for example, as hollow seals or lip seals. As can be seen in particular from Figure 25, such seals 109 formed as hollow seals can be suitably provided with moisture-tight seals between the plates 4 and 41 in different angular positions. The same applies to the lip seal formed by the seal 110 if the lip is provided with a metal reinforcement or the like, respectively, which can withstand the vacuum caused by the suction effect. These reinforcements can be omitted if the material strength or stiffness of the material used is so high that the pull of the suction forces on its surface does not allow the seal to rise.

In the context of the present invention, it is furthermore possible that the transverse tensioning part 15 - as schematically shown in Fig. 1 - consists of two parts 111, 112. The ends opposite the coupling parts 16 of the parts 111, 112 are connected by anchoring parts 113, for example a grating net, II; 29 93054 with counter-hooks or other most often resilient surface-retaining elements which can ensure the attachment of the individual parts 111, 112 of the transverse cross-section 15 inside the plate 4.41.

It can also be seen from Figure 21 that the length 114 of the longitudinal tensioning section 87 is greater than the length of the individual plates 4.41.

However, according to a further embodiment of the present invention, it is also possible, as schematically shown in Fig. 17, that any space 115 between the outer side of the wall 33 of the storage container 1 and the inner sides of the plates 4,41 is filled with foam, e.g. one-component foam. This is done by adding plastic in liquid form to this intermediate space 114 after the completion of the insulating structure, foaming therein and thus filling the intermediate space 115 completely. A further advantage of this solution is that the increase in volume caused by foaming the plastic causes a thrust of 4.41 on the plates in the direction of the transverse clamping parts 15,44,70,86, which provides prestressing to these transverse clamping parts. This eliminates any possible clearance between the plates 4.41, the wall 33 and the transverse cross-members 15. Thus, loosening of the plates 4.41 even during a long service life is hardly possible.

As further seen in Figures 19 and 20, the flanges delimiting the groove 12 may be of different lengths, with the longer flange located on the opposite side of the storage tank and the shorter flange on its side. In addition, v the overlapping profile portions 116,117 of the profiles 75,76 form sealing lips, since both profile portions 75,76 are telescopically formed in the region of their profile portions 117,116. This telescopic shape is provided so that the profile parts 116,117 run coaxially with the sheath of the tongue 11.

30 93054

It is also possible within the scope of the invention as shown in Figures 12 and 13, arranged in the transition region between the two plates, e.g. between the groove 12 and the outer side of the flange of the residual gap 118. This gap 118 may be formed by immersing the plastic profile during the foaming or milling.

As shown by the dashed lines in Figures 12 and 13, the central region of the plates may be provided with a transverse channel 119 connecting the gap 118 to the cavity 42. This gap 118 and transverse channel may be used to add a liquid sealant to fill the voids remaining during installation. . Through the transverse channel 119, this liquid sealant can also penetrate the cavity 42, which can be completely filled. This prevents condensation water from forming in this hollow space due to the strong temperature differences between the storage tank and the surrounding air, which would remain in these areas.

Instead of a liquid sealant, it is naturally possible to use slow-curing plastic foam or other types of casting compound.
