Cladding body assembly having a uniform outer surface, submarine antenna and submarine boat comprising the cladding body assembly and method for producing the cladding body assembly The invention relates to a cladding body assembly according to the preamble of Claim 1. The invention further relates to a submarine antenna and a submarine boat com prising the cladding body assembly according to the invention. The invention finally relates to a method for producing the cladding body assembly. 5 In a known submarine boat, a known, linear submarine antenna denoted as a flank array, is arranged on a hull of the submarine boat. Said submarine antenna has a transducer array comprising a plurality of waterborne sound sensors and/or hydro phones arranged horizontally in rows one behind the other along the hull and spaced 10 apart from one another in the installed position of the submarine antenna. Said known submarine antenna also has a cladding body assembly fastened to the hull, which provides protection against flow noise and mechanically protects the transducer array by means of a streamlined design. 15 A device for fastening a submarine antenna is disclosed in DE 10 2008 052 352 B3. DE 10 2004 037 987 Al discloses a further electro-acoustic submarine antenna. A known cladding body assembly has a plurality of cladding body sections arranged horizontally in rows, one behind the other along the hull in the installed position of the 20 submarine antenna, said cladding body sections being connected in a laminate com posite structure and/or in the manner of a groove-tongue connection, wherein end regions of adjoining cladding body sections overlap. In said known cladding body as sembly, joints remaining on the outer surface of the cladding body assembly between the end sections of adjoining cladding body sections are filled with a joint filler. As a 25 result, a uniform outer surface is produced on the cladding body assembly. As a result of this uniform outer surface, the radiation of interference sound from the cladding -2 body to the transducer array, which is caused by bending waves due to structure bome sound and turbulence, is avoided. A drawback with this known cladding body assembly is that for dismantling individual 5 cladding body sections, for example for maintenance purposes and/or for repairing the transducer array arranged behind said cladding body sections, often a large number of further cladding body sections have to be dismantled. In particular, due to the lay ered construction and/or due to the groove-tongue connection with which all adjoining cladding body sections respectively engage in one another, such a known cladding 1o body section may itself only be finally dismantled after dismantling all adjoining clad ding body sections on either side. Thus it may arise that for removing a cladding body section, for example, a total of up to ten cladding body sections have to be removed. Maintenance and/or repair to the submarine antenna is, therefore, associated with a high degree of effort. 15 The object of the invention, therefore, is to simplify the assembly when repairing a submarine antenna. The invention achieves this object by a cladding body assembly according to Claim 1, 20 comprising a submarine antenna according to Claim 7, comprising a submarine boat according to Claim 8 and comprising a method according to Claim 9. Relative to the known cladding body sections, the invention uses differently configured cladding body sections which have differently configured end sections. In particular, 25 end sections of adjoining cladding body sections do not overlap as in the prior art, so that individual cladding body sections may be dismantled from the hull, without adjoin ing cladding body sections also having to be dismantled. By means of the invention, however, it is possible to produce a uniform outer surface for the cladding body as sembly according to the invention. To this end, the invention not only uses a joint filler 30 but additionally uses a joint profile, which substantially contributes to bridging a joint gap of the joint between adjoining cladding body sections. Said joint profile has to be introduced into the joint and subsequently has to be able to last as long as possible in the joint. When producing the uniform outer surface, the invention makes use of the recognition that the known joint filler is used not only for filling a joint and/or a residual 35 joint but additionally as sliding means for introducing the joint profile into the joint and -3as adhesive for the durable fastening of the joint profile in the joint. In particular, there fore, a sliding means does not have to be used for introducing the joint profile into the joint and removed again and/or replaced by an adhesive for the durable fastening of the joint profile in the joint. 5 For maintenance purposes, the joint profile may be mechanically removed from the abutting cladding body sections, so that a cladding body section may be dismantled without adjoining cladding body sections also having to be dismantled. Optionally, for dismantling a cladding body section, the abutting joint profiles are initially cut through 10 and, after mounting, remains of the cut-through joint profiles are removed from the dismantled cladding body section as well as from the abutting cladding body sections. The cladding body assembly according to the invention comprises the joint profile which is at least partially arranged in the joint and which may optionally protrude on 15 the side opposing the outer surface and/or from an inner surface. Preferably, no re gions remain in which the joint profile is in contact with the end sections directly and/or without joint filler arranged therebetween. Finally, in the cladding body assembly, a joint gap of the joint is bridged, wherein the joint profile and optionally the joint filler used as adhesive substantially bridge the joint gap and, as a result, indirectly connect 20 together the adjoining cladding body sections. According to the method according to the invention, initially the joint filler is at least partially applied to the joint profile and/or to the adjoining first and second end sec tions of the adjoining cladding body sections fixed relative to one another and/or 25 mounted on the hull. The joint profile is subsequently introduced at least partially into the joint by using the applied joint filler as sliding means, wherein the joint gap of the joint is bridged. The joint filler is subsequently cured. In particular, the joint filler is vul canised when it is subjected to the ambient air. The cured joint filler in this case acts as adhesive and forms a material connection of the joint profile with the first and the 30 second end sections of the adjoining cladding body sections. Preferably, the joint profile is introduced into the joint such that it is positively con nected to the cladding body sections after being introduced into the joint, such that it is fixed at least locally in all directions perpendicular to one respective direction of the 35 joint path relative to the cladding body sections. The joint profile, therefore, is not able -4 to be inadvertently pressed out of the joint. Pushing and/or pulling the joint profile in the direction of the joint path is, however, preferably possible. The joint profile is thus arranged in the joint such that, by means of the joint filler as adhesive, a load-bearing connection no longer has to be produced. Instead, a fixing of the joint profile is already 5 substantially achieved by means of the positive connection. The joint filler also permits a fixing in the direction of the joint path and seals gaps which are potentially present between the joint profile and the end sections. Preferably, residual joints between a front portion of the joint profile and the abutting 10 end sections of the adjoining cladding body sections are additionally filled by means of the joint filler. It is advantageous to leave such residual joints which emerge from the outer surface in order to be able to produce a smooth transition between the end sec tions of the cladding body sections and the joint profile by filling up said residual joints with the joint filler. Optionally, the joint profile is also covered on its surface with the 15 joint filler, so that in this case the residual joints may also be configured as a single common residual joint. The residual joints may have different geometries. However, residual joints which ta per from the outer surface are preferred. Such residual joints may advantageously be 20 filled from the outside with the joint filler. In particular, air bubbles which could act dis advantageously on the otherwise stable fit of the cured joint filler and the joint profile in the joint have to be avoided, due to the variable pressure loads to which a subma rine boat may be subjected. 25 Preferably, the end sections of the adjoining cladding body sections abutting against the joint are configured such that the joint has a widened joint portion abutting against the joint gap in the direction of the outer surface. With such a configuration of the cladding body sections and/or the joint, the joint profile may advantageously be intro duced in the joint. Moreover, the joint profile may be configured such that it remains 30 fixed in the joint and does not push completely through the joint gap. Finally, the re sidual joints may also be advantageously provided in such a widened joint portion. Advantageously, the joint widens in the region of the widened joint portion from the joint gap to the outer surface of the cladding body assembly.
-5 Advantageously, the joint profile has a front portion arranged in the region of the wid ened joint portion, a rear portion and a web arranged in the region of the joint gap and connecting the front to the rear portion. In this case, the widths of the front and the rear portions exceed in each case at least locally a width of the joint gap. This ensures 5 the positive fixing of the joint profile in the joint. Advantageously, by pressing on the front portion of the joint profile in the direction of the web, the web is pressed into the joint gap. At the same time, in this case, the rear portion is pressed through the joint gap. The joint filler in this case acts as sliding 10 means. When pressed through the gap, said rear portion is pressed together and/or compressed along its width. Subsequently, said portion expands again to a width which at least locally exceeds the width of the joint gap. As a result, the joint profile is prevented from emerging from the joint in the opposing direction. Advantageously, the joint profile is completely prevented from moving back by suitable shaping of the rear 15 portion and/or the cladding body sections. As an alternative to pressing the joint profile into the joint, the joint profile may also be pushed and/or pulled into the joint along the joint path by using the joint filler as sliding means. The joint filler as sliding means reduces the frictional resistance so that such a 20 pushing and/or pulling or the above-described pressing of the joint profile is possible with a reasonable amount of force expenditure, as long as the joint filler is not yet cured and/or vulcanised. Preferably, in the front portion the joint profile has a bead which extends from the 25 outer surface in the direction of the web. The bead facilitates the pressing of the joint profile into the joint. In particular, the web is pressed by means of the bead, and/or by pressing into the bead, into the joint gap and/or partially through the joint gap to a suf ficient extent that the rear portion is completely pressed through the joint gap. Forces may, therefore, be specifically transmitted to the web. As the web is also deformed by 30 pressure, said web potentially has to be temporarily pressed deeper in the gap than might be necessary relative to the position to be ultimately adopted. Without the bead, this would only be possible if at the same time a relatively large amount of deforma tion energy were used for deforming the front portion of the joint profile. In contrast, the bead permits an introduction of the joint profile into the joint which saves the ex 35 penditure of force.
-6 Preferably, after introducing the joint profile into the joint the bead is filled with the joint filler which is used as sliding means and/or adhesive, or with a further joint filler in a similar manner to the residual joints. As a result, the uniform and preferably relatively 5 smooth surface is once again achieved. Alternatively or additionally, the bead is completely or partially filled with a partial pro file, wherein a connection of the partial profile to the joint profile is produced again by means of the joint filler as adhesive. In this manner, the regions to be filled with the 1o joint filler are kept relatively small, so that even a relatively rapid curing of the joint filler used is achieved. The joint profile may, therefore, be regarded as a partial profile, which is initially fastened in the joint and is subsequently completed by adding a sec ond partial profile. 15 In a development, generally the first partial profile is fastened as a joint profile in the joint and subsequently completed by adding at least one second partial profile, wherein a bead of the first partial profile does not necessarily have to be filled by means of the second partial profile. Instead, further alternative configurations of the joint profile are possible in which the joint profile is made up of a plurality of partial 20 profiles. In this case, a plurality of partial profiles may be optionally arranged and/or fastened at the same time or one after the other in the joint. Preferably, the joint profile is an elastomer. For example, the joint profile is a rubber and/or a natural rubber and/or profile comprising synthetically produced rubber, Such 25 a joint profile may advantageously be introduced into the joint in the manner according to the invention and fulfil its function there until an abutting cladding body segment is dismantled. Preferably, the filler is a polyurethane sealant. The filler does not have to seal any so regions of variable pressure or a water-filled region from an air-filled region, as the submarine antenna is under water, and thus water applies the same pressure on both sides of the cladding body assembly. However, the polyurethane sealant is very suit able as sliding means, adhesive and filler, as the invention has identified.
-7 Preferably, the invention uses a material comprising a polyurethane as filler, particu larly preferably a polyurethane sealant and/or a polyurethane-based sealant, quite particularly preferably an elastic 1-component polyurethane sealant which, in particu lar, may be injected and upon contact with air is cross-linked and cured and/or vulcan 5 ised, but remains flexible. The cladding body assembly according to the invention is preferably produced by means of the method according to the invention. 10 The end sections of the cladding body sections are preferably configured symmetri cally relative to one another and uniformly curved. As a result, a symmetrically config ured joint profile may be used. The joint profile is preferably adapted to the end sections of the abutting cladding 15 body sections at least in the region of the joint gaps. Also in the region of the front portion, but not where residual joints are arranged, the joint profile is preferably adapted to the end section of the abutting cladding body sections. The residual joints preferably have a width of 0.5 to 2 cm on the outer surface of the cladding body as sembly. 20 The cladding body assembly preferably has an overall length of between 20 and 40 metres, particularly preferably of between 25 and 35 metres. The cladding body as sembly preferably has between eight and twenty cladding body sections, in each case of 2 to 2.5 metres in length. After introducing the joint profile into the joint, in particular 25 after the curing of the joint filler, the outer surface of the cladding body assembly is preferably smoothed and/or polished in the region of the joints. As a result, potentially protruding regions of the joint profile and/or the cured joint filler are removed, so that a smooth outer surface of the cladding body assembly results. so The joint profile preferably has a maximum width of 3 to 5 cm and maximum depth of 2 to 4 cm. The joint in this case preferably has a depth of 1 to 3 cm. In particular, the cladding body segments have a thickness of between 1 and 3 cm. The rear portion of the joint profile preferably protrudes up to 2 cm, particularly preferably up to 1 cm, out of the joint gap. 35 -8 The bead in the joint profile preferably has a depth of 0.5 to 2 cm, particularly prefera bly of between 1 and 1.5 cm. The width of the bead on the outer surface is preferably between 1 and 3 cm. 5 The web between the adjoining cladding body sections preferably has a width of less than 1 cm. For pressing the rear portion of the joint profile through the joint gap, said rear portion is preferably able to be compressed to the width of the web or even fur ther. 10 The submarine antenna according to the invention comprises a plurality of waterborne sound sensors and the cladding body assembly according to the invention, which at least partially surrounds said waterborne sound sensors. The submarine boat according to the invention may substantially be any known sub 15 marine boat otherwise corresponding to the prior art, but which in contrast with known submarine boats has the cladding body assembly and/or submarine antenna accord ing to the invention. According to an advantageous development of the method according to the invention, 20 for repairing a submarine antenna comprising a plurality of cladding body sections, initially all and/or both joint profiles adjoining a cladding body section to be dismantled are substantially removed. Alternatively, said joint profiles are initially simply cut through and removed at a later time. Subsequently, the cladding body section is dis mantled, so that the transducer array is exposed and accessible for maintenance 25 and/or repair. Subsequently, the dismantled cladding body section or a further clad ding body section replacing the dismantled cladding body section is mounted. Accord ing to the invention, a uniform outer surface of the cladding body assembly is recon structed by means of the method according to the invention. 30 Further embodiments are revealed from the claims and from exemplary embodiments described in more detail with reference to the drawings, in which: Fig. 1 shows a detail of a cladding body assembly comprising two end sec tions of adjoining cladding body sections and a joint profile arranged 35 therebetween in a joint as well as residual joints filled with joint filler -9 and a filled bead in a sectional view perpendicular to the direction of the joint path according to a first exemplary embodiment of the inven tion; 5 Fig. 2 shows a detail of a cladding body assembly according to a second exemplary embodiment of the invention comprising residual joints of different shape relative to the first exemplary embodiment of Fig. 1; Fig. 3 shows a detail of a cladding body assembly according to a third ex 10 emplary embodiment of the invention comprising the rear portion of the joint profile of different configuration relative to the first exemplary embodiment of Fig. 1 and without a bead; Fig. 4 shows a detail of cladding body assembly according to a fourth ex 15 emplary embodiment of the invention comprising the joint profile formed from two partial profiles relative to the third exemplary em bodiment of Fig. 3 and residual joints according to the second exem plary embodiment of Fig. 2; 20 Fig. 5 shows a detail of a cladding body assembly according to a fifth ex emplary embodiment of the invention comprising a partial profile ad ditionally arranged in the bead relative to the first exemplary em bodiment of Fig. 1 for completing the joint profile; 25 Fig. 6 shows a sectional view for illustrating the introduction of the joint pro file into the joint when producing the cladding body assembly accord ing to the first exemplary embodiment of Fig. 1 and Fig. 7 shows a detail of a hull of a submarine boat comprising a side an 30 tenna which has a cladding body assembly comprising a partially produced uniform surface and a cladding body segment separated by the open joints, in a side view. Fig. 1 shows a detail of a cladding body assembly I which in a sectional view shows a 35 second end section 4 of a first cladding body section 6 and a first end section 8 of a -10 second cladding body section 10 perpendicular to a joint 2. Said second end section 4 of the first cladding body section 6 and the first end section 8 of the second cladding body section 10, separated by the joint 2, are arranged adjacent to one another and configured symmetrically to one another. 5 The cladding body section 6 has a first end section located on the other side of the detail shown, which is preferably configured in a similar manner to the first end section 8 of the second cladding body section 10, and to which a further joint and then a fur ther cladding body section may be adjoined. Accordingly, also the second cladding 10 body section 10 has a second end section which may be configured in a similar man ner to the second end section 4 of the first cladding body section 6. The cladding body sections 6 and 10 as well as further cladding body sections adjoined thereto are se curely fixed together relative to one another, in particular all mounted on a hull of a submarine boat. 15 A joint profile 12 is arranged in the joint 2. The joint profile 12 has a front portion 14, a web 16 adjacent thereto and a rear portion 18 adjacent thereto in turn. The web 16 in this case bridges a joint gap 20 of the joint 2. The joint profile 12 is an elastomer and/or sealing rubber which is adapted in its shape to the web 16 and/or in the region 20 of the joint gap 20 and partially also on the front portion 14 to the joint 2 and/or to the end sections 4 and 8. Also, the rear portion 18 has contact regions with the end sec tions 4 and 8, in which it is adapted to said end sections 4 and 8. In particular, the rear portion 18 engages behind the end sections 6 and 8. A maximum width of the rear portion 18 thus exceeds a maximum width of the joint gap 20. Also, a maximum width 25 of the front portion 14 exceeds said maximum width of the joint gap 20. The joint pro file 12 is thus positively connected to the cladding body sections 6 and 10 fixed se curely relative to one another, but could be moved perpendicular to the cutting plane and/or in the direction of the joint path. This is, however, prevented in the cladding body assembly produced by the joint profile 12 being adhesively fixed to the end sec 30 tion 4 and 8 of the cladding body sections 6 and 10 by means of a joint filler 22, which in this case takes on the function of an adhesive. The joint filler 22 is also arranged in residual joints 24 and 26 as well as in a bead 28. By means of the joint filler 22 in the residual joints 24 and 26, a smooth and advanta 35 geously streamlined transition is produced between a surface of the first cladding - 11 body section 6 and/or second cladding body section 10 and a surface of the joint pro file 12 and/or its front portion 14. As a result, a uniformly smoothed outer surface 30 of the cladding body assembly 1 is achieved. 5 If, however, in a deviation from the invention, the joint profile 12 were to abut against the cladding body sections 6 and 10 in the region of the outer surface 30 substantially directly and/or without the joint filler introduced, at least the smallest gaps would re main the region of the outer surface 30, which under water could lead to turbulence and optionally could also provide a contact surface for removing the joint profile 12. 10 The bead 28 facilitates the pressing of the joint profile 12 into the joint, as described in more detail below with reference to Fig. 6. When the joint profile 12 is fixed in the joint, however, the bead 28 is no longer required and is filled with the joint filler 22 for the uniform outer surface 30 of the cladding body assembly 1. 15 Fig. 2 shows a detail of a cladding body assembly 1' in a sectional view perpendicular to the direction of the path of the joint 2, according to a second exemplary embodi ment of the invention. Said second exemplary embodiment only differs from the first exemplary embodiment in that, instead of the joint profile 12, a joint profile 12' is pro 20 vided which is only of different configuration relative to the joint profile 12 in regions which define the residual joints 24' and 26'. Accordingly, the residual joints 24' and 26' and/or the cured joint filler 22 located therein have a different shape relative to the residual joints 24 and 26 and/or relative to the joint filler 22 cured therein. As a result, it is only intended to be illustrated by way of example that the residual joints 24 and 26 25 and/or 24' and 26' may have different shapes. Alternatively, other shapes are also possible. Advantageous, however, are shapes in which during the production of the uniform outer surface 30 the joint filler 22 may be advantageously introduced in the residual joints 24 and 26 and/or 24' and 26', such that no air bubbles remain between the joint filler 22 and the cladding body sections 6 and 8 and/or between the joint filler 30 22 and the joint profile 12 and/or 12'. Fig. 3 shows a detail of a cladding body assembly 1" according to a third exemplary embodiment of the invention which in turn differs relative to the joint profile 12 of the first exemplary embodiment according to Fig. 1 by a joint profile 12" which is of differ 35 ent configuration. The joint profile 12" is provided for pulling and/or pushing into the -12 joint 2. A rear portion 18' of the joint profile 12" may, therefore, be configured to be wider than the rear portion 18 according to Figs. 1 and 2, as it does not have to be pressed through the joint gap 20. Also, a bead does not, therefore, need to be pro vided in the joint profile 12" according to the bead 28 of the exemplary embodiments 1 5 and 2. For pulling and/or pushing the joint profile 12" into the joint 2, said joint profile 12" is provided at least partially, but preferably on all subsequent contact surfaces with the end sections 4 and 8, with a thin layer of joint filler 22. Alternatively or addi tionally, the joint filler 22 is at least partially applied to the end sections 4 and 8. The joint filler 22 acts as sliding means when pulling or pushing the joint profile 12" into the 1o joint 2. Subsequently, the joint filler 22 is vulcanised so that it acts as adhesive and fixes the joint profile 12" securely in the joint 2. The joint filler 22 in all exemplary embodiments is preferably a polyurethane-based sealant. In particular, for example, an elastic 1-component polyurethane sealant is 15 used as the joint filler 22. In alternative embodiments, however, a further means may be used as sliding means, adhesive and filler. Also, the joint profile may optionally be formed from a different elastomer or a different flexible material. Both the joint filler 22 and the joint profile 12 and/or 12' or 12" are, however, preferably resistant to sea wa ter so that the cladding body assembly may be used on a submarine boat. 20 Fig. 4 shows a detail of a cladding body assembly 1' with the joint profile 12' and residual joints 24' and 26' according to the second exemplary embodiment of Fig. 2 formed from two partial profiles 32 and 34, compared to the third exemplary embodi ment of Fig. 3. The multi-part construction of the joint profile 12"' has four advantages 25 when introducing the joint profile 12"' into the joint 2. More specifically, the partial pro file 32 may be pulled and/or pushed into the joint 2 using a smaller amount of force expenditure than the joint profile 12", as it has fewer contact surfaces with the clad ding body sections 6 and 10. After introducing the partial profile 32 into the joint 2, the partial profile 34 is fixed by means of the joint filler 22 as adhesive to the partial profile 30 32, and to the end sections 4 and 8, of the cladding body sections 6 and 10. Finally, the residual joints 24' and 26' are filled with the joint filler 22. Fig. 5 shows a detail of a cladding body assembly 1"" according to a fifth exemplary embodiment of the invention which is substantially the same as the first exemplary 35 embodiment of the invention of Fig. I but shows a joint profile 12"" configured in two -13 parts with the partial profiles 32' and 34'. In this case, the partial profile 32' may in turn be regarded as a joint profile which is supplemented by the partial profile 34'. The partial profile 34' in this case is arranged in a bead 28' of the partial profile 32'. 5 Thus the partial profile 32' may be initially introduced as the joint profile 12 of the first exemplary embodiment of Fig. 1 into the joint 2. Subsequently, the bead 28' is par tially filled by means of the partial profile 34', so that subsequently comparatively less and/or a thinner layer of the joint filler 22 has to be applied for producing the uniform outer surface 30. The joint filler 22 is, therefore, able to be cured more rapidly. 10 Fig, 6 shows a sectional view for illustrating the introduction of the joint profile 12 of the first exemplary embodiment of Fig. 1 into the joint 2, when producing the cladding body assembly 1 and/or for producing the uniform outer surface 30. At least on con tact surfaces of the joint profile 12 with the end sections 8, 4 of the cladding body sec 15 tions 6, 10, the joint filler 22 is arranged at least partially as sliding means. Illustrated by an arrow P, a force is exerted in the direction of the arrow on a base of the bead 28 in the direction of the web 16. Fig. 6 shows a moment during the pressing-in process, in which the front portion 14, as provided, is already in contact with the end sections 4 and 8 of the cladding body sections 6 and 10. The rear portion 18, however, is not yet 20 completely pressed through the joint gap 20. To this end, the web 16 which is tempo rarily compressed under the exerted pressure has to be pressed further into the joint gap 20. This is advantageously achieved by means of the bead 28. In particular, in this case, only a small portion of the exerted force is used for temporary deformation of the front portion 14 of the joint profile 12. Without such a bead, however, a relatively 25 high force would have to be exerted for pressing the web 16 into the joint gap 20, as a relatively larger proportion of the exerted force would deform the front portion 14 and would press against the end sections 4 and 8 of the cladding body sections 6 and 10. The bead thus advantageously facilitates the pressing of the joint profile 12 into the joint 2. 30 Fig. 7 shows a detail of a hull of a submarine boat 36 with a side antenna 38 which comprises the cladding body assembly 1 with the partially produced uniform outer surface 30 in the region of the first cladding body section 6 and the second cladding body section 10, and further cladding body sections 44 and 46 separated by open -14 joints 40 and 42 and arranged adjacent to the second cladding body section 10. A direction of the joint path for the joint 40 is indicated by way of example by an arrow R. The cladding body sections 6 and 10 are, as disclosed in Fig. 1, connected together 5 by means of the joint profile 12 and the joint filler 22 such that they have a common outer surface. In particular, the surface is smooth so that the production of turbulence is counteracted, in particular when the submarine boat 36 is located in the water and/or below the water surface, and measurements are carried out by means of a transducer array arranged in a concealed manner behind the cladding body sections 10 6, 10, 44 and 46. In the view shown, the cladding body section 44 may be dismantled in order to be able to maintain and/or repair the transducer array. For dismantling the cladding body section 44, only the joint profiles according to the joint profile 12 have to be removed 15 from the joints 40 and 42, and/or as shown, are removed. The cladding body sections 10 and 46 adjoining the cladding body section 44, however, do not have to be re moved for dismantling the cladding body section 44, in particular as the end sections of adjoining cladding body sections 10 and 44 and/or 44 and 46 do not overlap as in the prior art, but in any case are separated from one another by joint gaps 48 and 50 20 according to the joint gap 20. After maintenance and/or repairs, the cladding body section 44 or a cladding body section replacing said cladding body section 44, is again mounted between the clad ding body sections 10 and 46, and subsequently a joint profile is again inserted into 25 the joints 40 and 42 in the manner according to the invention. Finally, residual joints and beads which are possibly present are sealed so that the entire cladding body as sembly 1 once again has the uniform outer surface 30. Optionally, the outer surface is ground and/or polished in the region of the joints 40 and 42 in order to remove any protruding portions of the joint profile and/or the filler 22 and to smooth the outer sur 30 face 30. All of the features cited in the above description and in the claims are able to be used both individually and in any combination with one another. The disclosure of the in vention is therefore not limited to the disclosed and/or claimed combination of fea 35 tures. Instead, all combinations of features are to be considered as disclosed.
