An independent claim is also included for a method of manufacturing a structural profile.

Description

The invention relates to a structural profile with a profiled sheet, wherein the profiled sheet has a plurality of elongated, in particular parallel ridges with two flanks. The invention also relates to a method for producing such a structural profile as well as a ship's hull, container body, floor element, heating or cooling device and roofing element with a structural profile.

Structure profiles are used today for many different purposes. From the DE 35 13 765 A1 For example, a boat is known whose walls consist of such a structural profile. In this case, two profile sheets, each having a plurality of bends, so that in each case a trapezoidal pattern results in cross-section, attached to each other, so that form cavities between the two profile sheets. These can be foamed, for example, with a polyurethane foam. The disadvantage is that the many bends introduced into the metal sheets increase the stability of the structural profile in one direction but do not contribute to increasing the stability in another direction. To counteract this problem, in addition stiffening elements are inserted and secured in the recesses between two adjacent cavities.

From the DE 26 28 801 A1 is a manufactured as a precast structural element for building construction, which also includes a generic structural profile. In this case, the profile sheet, which is also present in the form of a trapezoidal sheet, disposed between an inner and an outer cover layer, wherein the cover layer are secured to the trapezoidal sheet spaced from the longitudinal straps. The resulting gaps are then filled with a hard foam. Such finished parts should be used as a wall element for building construction and are used so that the longitudinal extension of a plurality of elevations in the profile sheet, which results from bending or bending of the sheet, in the installed state in the vertical direction.

Structural profiles of the generic type can therefore be used in house construction as a roof, wall or floor element or, for example, as a living container or empty container. They can also be used in shipbuilding as a ship's hull or for the interior fittings of a motor vehicle, for example an expedition vehicle. In addition, they are versatile as a support and substructure for a variety of applications usable.

The US 3,943,586 A describes a generic structural profile.

The invention is therefore an object of the invention to provide a structural profile and a method for its production and to provide various applications for such a structural profile, with which the stability of the structural profile is increased and yet easy, fast and inexpensive to produce and has a low weight ,

The invention solves the problem set by a structural profile with the features of the main claim. In a preferred embodiment, the profile sheet is designed as a trapezoidal sheet.

Due to the in a common orientation, in particular parallel ridges whose direction defines the longitudinal direction of the structural profile below, the stability of the profile sheet is already increased. As a result, the profile sheet is more stable against pressure loads acting in the longitudinal direction of the structural profile, ie parallel to the elevations. Furthermore, buckling of the structural profile about an axis in the main plane of the structural profile perpendicular to the longitudinal extent of the elevations is made more difficult. Through cross members with legs and corresponding recesses, it is possible to fix the cross member on all sides of the structural profile. When welding the profile sheet to the cross member, this can also be done on the longitudinal side in order to increase the stability.

According to the invention, in each case at least one recess is provided in the flanks of the elevations through which at least one cross member is guided. The recesses are introduced into the flanks in such a way that they are aligned with one another so that the usually straight cross member can be pushed or inserted through a plurality of recesses arranged one behind the other. The cross member extends in a particularly preferred embodiment in a direction transverse, substantially perpendicular or perpendicular to the direction of the elevations, that is substantially in the transverse direction of the profile sheet or at an acute angle thereto. The cross member may be configured for example in the form of a metal rod, a metal profile or a square tube or in a similar form and for example made of a light metal, for example aluminum. Of course, depending on the application, other materials and shapes are conceivable. Closed hollow profiles have a high bending stiffness in comparison to the weight, so that they are particularly well suited for insertion into the recesses. Even bends can also be used as cross beams when the Recesses are arranged in accordance with the profiled sheet. Characterized in that the structural profile has at least one cross member, the stability of the profile is also increased in this direction, so that the structure profile can be used to a greater extent as a floor and ceiling construction, for example in the building of houses. In particular, a load of the structural profile perpendicular to its main plane or expansion surface, ie perpendicular to the longitudinal and the transverse direction of the structural profile, is now much better possible.

In order to increase this effect even more, advantageously, a plurality of cross members may be guided by recesses provided in the flanks, wherein the cross members are arranged in particular parallel to each other. Due to the number and shape of the parallel ridges provided in the profiled sheet, the stability is thus increased in one direction by the number of cross members arranged and by their profile in a second direction. The cross members may also be oriented diagonally to the longitudinal extent of the elevations, also cross members may be provided in different orientations or orientations in the structural profile to make load-specific stiffeners.

In order to ensure a better stability and positional stability between the at least one cross member and the profiled sheet, the at least one cross member can be connected to the profiled sheet, for example welded. Alternatively, for example, a bond or other type of attachment, for example by rivets or screws conceivable.

Advantageously, a cover, in particular a cover plate is arranged on a top side and / or on an underside of the profile sheet opposite the top side. The cover may for example consist of a metal, for example aluminum or another suitable material. It is conceivable, for example, drywall panels such. As OSB boards, MDF boards, chipboard, fiberboard, insulation boards, gypsum board, gypsum fiber board or similar planar components to order. This is to be made dependent on the later desired use of the structure profile. The upper side or the lower side of the profiled sheet is defined by planes which are generally perpendicular to the longitudinal direction and the transverse direction of the profiled sheet and extend parallel to the plane spanned by the longitudinal and transverse directions. The fact that these pages are at least partially clad with a cover plate, the variety of possible uses of such a structural profile is further increased. So it is now possible to use the structure profile even easier than wall, floor and ceiling element in construction, since the pages can now be easily disguised, for example, plastered or plastered.

In addition, cavities formed by the at least one cover or the at least one cover plate and the profiled sheet can be filled, for example, foamed. In addition to a foaming other types of sound and / or thermal insulation can be introduced into the cavities, such as mineral fibers, fiber in general or organic material. The materials can be introduced in different ways, in addition to a conventional stuffing a blow-in insulation is possible and provided. If a cover plate is arranged on the upper side of the profiled sheet, the cavities between the profiled sheet and the cover sheet arise in the areas which are located between the elevations in the profiled sheet. If the cover plate is arranged on the underside of the profile sheet, the cavities between the profile sheet and the cover sheet in the areas of the elevations of the profile sheet arise. By foaming these cavities on the one hand, the stability of the structural profile can be further increased and on the other hand, the connection between the individual components, ie profile sheet, cover plate and cross member, further improved. In order here to ensure the simplest possible filling of the cavities with the foam or other material, further openings may be provided in the flanks of the profile sheet, through which the foam or the filler material can flow from one cavity into the adjacent cavity. If, for example, not all cavities are to be filled or, for example, only one cover plate is arranged on the profiled sheet so that the cavities to be filled do not directly adjoin one another, conduit or connecting elements can also be provided between the cavities through which the filling material passes from a cavity into the cavity can arrive next. It is envisaged that the cross member is formed as such a conduit element.

In particular, in housing today strict requirements are made of thermal insulation and thermal insulation properties of the building materials used. If such a structural profile, for example, used as a wall element, it may be useful to provide a heat-insulating layer between the profiled and at least one of the cover sheets used. This can for example consist of a plastic, which is arranged between the two sheets or components. Thus, the thermal insulation of the structural profile is significantly increased even in the event that both the cover plate and the profile sheet made of a metal. Alternatively, for example, one of the Cover plates or the Profiblech be coated at least in the contact region of the two sheets with a plastic. A complete coating, for example with a plastic, is conceivable.

In order to be able to connect two identical structural profiles with one another in an especially simple manner, connecting elements are provided, for example, at the edges of the structural profiles. This can be achieved that two identical structural profiles, for example, engage or hook into each other and are locked against each other at least in one direction. This greatly simplifies the connection of two structural profiles and thus reduces the assembly effort.

Form-fitting elements can also be arranged or formed on the end faces of the profiled sheet in order to be able to complete the cavities formed by the covers, for example by inserting and locking side sheets which have receptacles corresponding to the form-fitting elements. Plug-in connections between a plurality of structural profiles or structural profile units can also be produced by the interlocking elements, which can be used as preassembly elements in boat production, for example. As a result, a plurality of structural profiles can be arranged in a defined manner with respect to one another and finally joined, for example, welded.

Within the elevations and other recesses may be arranged to attach attachments or, for example, to introduce foam material can. In a trapezoidal profile, the recesses may be arranged on the bearing surfaces for the covers.

The profile sheet may have at least one opening and / or bead. The arrangement of an opening, the weight of the profile sheet and thus the subsequent structural profile can be reduced. An increase in stability can be made possible by the arrangement of collars, flanges and / or beads. Accordingly, collars or flanges may be formed on the recesses and / or openings of the profile sheet.

• a) Einbringen von Ausnehmungen in ein bereitgestelltes, ebenes Blech,
• b) Abkanten des Bleches an vorbestimmten Stellen, so dass ein Profilblech mit einer Mehrzahl langgestreckt, vorzugsweise in Längsrichtung in gemeinsamer Orientierung, verlaufender Erhöhungen mit jeweils zwei Flanken ausgebildet wird und sich zumindest einige der eingebrachten Ausnehmungen in den Flanken befinden,
• c) Einschieben wenigstens eines korrespondierend zu den Ausnehmungen ausgebildeten Querträgers in die eingebrachten Ausnehmungen, die sich ausschließlich in den Flanken befinden.

A method according to the invention for producing such a structure profile comprises the following steps:

• a) introducing recesses into a provided, flat sheet metal,
• b) folding the sheet at predetermined locations, so that a profile sheet with a plurality of elongated, preferably in the longitudinal direction in a common orientation, extending ridges with two flanks is formed and at least some of the recesses introduced are located in the flanks,
• c) insertion of at least one corresponding to the recesses formed cross member in the introduced recesses, which are located exclusively in the flanks.

By this method, a described structure profile is particularly simple, inexpensive and fast to produce. The cross members are preferably permanently connected to the profile sheet, for example, riveted, welded or glued and then planked. In addition, cover sheets may be disposed and secured to the top and / or bottom of the profile sheet to form voids between the projections which are foamed to increase rigidity. A reversible connection or attachment to each other is also possible, for example by a screw or plug connection.

A structural profile described here can be used in many other applications in addition to the already described use in house construction as a roof, wall or floor element. Thus, it is possible, for example, from the above-mentioned structural profiles living container, for example, for construction site equipment to produce. Also in vehicle construction, for example, for expedition vehicles, the above structural profiles for container structures can be used. In particular, in vehicle superstructures, it is possible and provided that the structure profile is provided with a bullet-resistant layer, for example with a fiber-reinforced composite insert, which is applied to the profiled board. Similarly, clearances and spaces can be filled with a bullet-proof material to provide protection against explosions or projectiles. The structural profile provides an additional crumple zone and energy conversion zone. In shipbuilding, it is possible to use the structural profiles in the fuselage, for example, for catamarans. In addition, they can serve as a substructure for supporting a wide variety of devices, for example solar panels in a solar power plant. The structural profile may be formed as a cooling device with channels for the passage of coolant, for example, to cool solar cells and at the same time to store the heat dissipated in a memory. The structure profile can be used as a roofing element, as well as a floor element, possibly with a heating or cooling device.

Here, a wide variety of configurations of the structural profiles are conceivable. In particular, a wide variety of functional units can be accommodated in the cavities between the at least one cover plate and the profiled sheet. So it is conceivable, for example, in case the Structural profiles are used as a floor element to accommodate in these cavities underfloor heating. In addition, pipes, as they are needed in house construction, can also be laid in these cavities. The cables required in this way can be prefabricated at the factory so that the actual construction can be further accelerated. In addition, the stability and structural properties of the structural profile can be individually adapted via various forms of elevations, for example trapezoidal, triangular or rectangular elevations. Since this does not involve much effort in the production process, a wide variety of profile shapes can be used here flexibly and quickly. Due to the different profiles, only the position of the recesses to be introduced into the profiled sheet provided, as well as possibly the angle and the position of the folds to be produced, changes to produce the desired elevations.

Even when attaching the cover plates a variety of mounting options are conceivable. These can be connected to each other, for example via spot welds, but there are also adhesive techniques, riveting or screw connections conceivable. Ultimately, any conceivable method of attachment can be used. Which is actually used depends not only on the desired application but also on the materials used.

1 shows a flat sheet after the process step a) of the method according to the invention for producing a structural profile. In the sheet are already recesses 4 introduced in the in 1 shown embodiment in several rows are arranged in alignment one behind the other. These rows extend in the transverse direction of the sheet. As can be clearly seen, this transverse direction does not mean that it is a shorter extension of the sheet than, for example, in the longitudinal direction. As already described, longitudinal direction merely means that this is the direction in which the parallel ridges extend, which will be described later. The recesses 4 are - as in 1 shown - preferably arranged exclusively in those areas of the sheet, later the flanks 6 make, not in the raises. The sheet is bent in a later process step at the positions shown by dashed lines. The areas between the flanks 6 lie in the final state in an upper and a lower level.

This in 1 Sheet shown has additional recesses 8th which are not aligned with the recesses 4 are arranged. These additional recesses 8th can be both in the flanks 6 as well as in the areas between the flanks 6 are located. Through the recesses 8th the net weight of the sheet and thus the subsequent structure profile is reduced. By a special arrangement of the additional recesses 8th is the stability of the profile sheet 2 not reduced. An increase in stability is due to the Arrangement of collars, flanges and beads allows. So can at the recesses 4 , the additional recesses 8th and / or openings 10 Collars or flanges be formed. The openings 10 are also in the later flanks 6 intended. Through these openings 10 can be a filler, with which the between the sheet and a in 1 cover plate not shown 12 resulting cavities 14 to be filled, from a cavity 14 to cross into a neighboring one.

2 shows a section of the profile sheet 2 after method step b), in which the sheet is folded. One recognizes in the flanks 6 the raises 16 in the in 2 shown embodiment are designed trapezoidal, the recesses 4 that, as in 1 are arranged in three rows one behind the other and in the transverse direction of the profile sheet 2 extend. Through these recesses 4 will later become crossbeams 18 guided. The recesses 4 and according to the cross member 18 can have different cross-sectional shapes, in the 1 and 2 in each case only one cross-sectional shape is shown by way of example, namely a U-shaped configuration with lateral extensions at the upper ends, alternatively, for example, a rectangular or nearly rectangular cross-section is provided. In the flanks 6 There are also additional recesses 8th , which serve the weight saving in the present case. The same applies to the recesses, which can be arranged in an elevation. In the raises 16 are in the 2 shown embodiment holes 20 represented in the fasteners can be introduced, for example, a in 2 not shown cover 12 in the form of a cover plate on the profile sheet 2 to fix.

At the transverse side edges of the profile sheet 2 are alignment elements 24 formed in the form of projections or tabs, the function of which is explained in more detail later as form-fit elements. The alignment elements 24 can, as in 1 and 2 shown on the flanks 6 be educated. Alternatively, the alignment elements 24 also at lower portions of the folded profile sheet 2 and / or at the upper plateau forming portions, the elevations 16 , between the flanks 6 arranged. The lower sections are on the side of the flanks 6 that the upper sections, the elevations 16 , is opposite. In principle, it is possible that the alignment elements 24 only available on one side edge.

3a to 3c show embodiments of a profile sheet 2 in which in the flanks 6 provided recesses 4 already cross member 18 are introduced. Through these crossbeams 18 will the stability of the profile sheet 2 and thus the structural profile significantly increased because a bend about an axis parallel to the folding or Abkantlinien prevented or at least significantly more difficult. In the in 3a and 3b the embodiments shown, the cross member extend 18 parallel to each other and perpendicular to the longitudinal extension of the elevations 16 or flanks 6 , The direction in which the raises 16 extend parallel to each other, in this case, the longitudinal direction, the direction of the cross member 18 , called the transverse direction of the structure profile. However, this is merely a naming of the two directions to distinguish them from each other. A restrictive meaning does not apply to these terms.

It can be seen that exemplarily in the lower part of the 3a in the raises 16 drilling 20 are provided. Through this fasteners can be performed to a cover plate not shown as a cover 12 to fix. At the same time in the holes 20 introduced fasteners also used to make a connection between the profile sheet 2 and through the recesses 4 in the flanks 6 guided crossbeams 18 to reach. Again, screw or rivet can be provided. Alternatively, spot welds can be made at these locations to the profile sheet 2 with the crossbeams 18 connect to. Basically, the crossbeams 18 , which are formed in the illustrated embodiment as a hollow profile with an approximately rectangular cross section, fixed to the profile sheet 2 connected for maximum stability. Alternatively to the parallel orientations of both the elevations 16 as well as the cross member 18 These can also be aligned at an angle to each other, also the cross member 18 have an arc shape, in which case the recesses 4 in the flanks 6 are arranged corresponding to the arch shape or a curvature of the structural profile corresponding to the course of the arc is formed.

The profile height h, ie the height of the elevations 16 or the distance of the elevations from lower sections that serve as basic sections 160 can be designated identical to the height S of the cross member 18 minus the double wall thickness d of the material in the region of the elevations 16 , Both the height h of the elevations 16 as well as the height S of the cross member 18 can vary, they do not have to be identical across the entire transverse direction. The heights h and S correspond advantageously with each other. In the 3a is shown that over the entire transverse direction, the height h of the elevations and the recesses is so large that the respective cross member 18 can be inserted and the recesses 4 in the flanks 6 completely or almost completely filled, so that already by introducing the crossbeam 18 a basic stability is achieved, which can be increased by an additional fixation, such as gluing, welding or screwing. The underside of the crossbeam 18 in the 9 is called base b, lies on the base section 160 on or just above it.

This in 3c illustrated, not covered by the invention embodiment shows a curved profile sheet 2 in which the cross member 18 passing through several recesses 4 of the profile sheet 2 extends, with the bend or arch shape of the profile sheet 2 corresponds. The recess 4 is designed as an open cross section, so that a part of the cross member 18 over the flanks 6 stands or concludes with these. It can also be a closed cross section of the recess 4 be provided; in an open cross-section is advantageously a positive locking with the cross member 18 provided, for example, by an upwardly tapering cross-sectional configuration.

4 shows a section of another profile sheet 2 in which there is a closing bar on one edge 22 located. This serves on the one hand the further increase in stability of the profile sheet 2 and the structural profile and, on the other hand, the lateral closure of cavities formed between the cross members 18 and the profile sheet 2 arise. It can also be seen that the alignment elements 24 in this embodiment on the end strip 22 protrude. Through the alignment elements 24 is an alignment of different structural profiles to each other or other components or structures particularly easy. They can also be parts of connecting and locking means with which two structural profiles can be connected to each other.

In the 4 can also be seen that the cross member 18 corresponding to the recesses 4 in the flanks 6 are formed and fill them completely or at least almost completely, so that the flat intermediate areas between the flanks 6 So the raises 16 and the basic sections 160 , parallel to the top and bottom of the cross member 18 run and possibly rest on this. The crossbeams 18 may be formed as a solid profile, box profile, as a closed or open hollow profile, as a T or double T-profile or the like. Corresponding to the carrier profile are the recesses 4 in the flanks 6 educated. The crossbeams 18 extend over the entire height of the flanks 6 , so after the application of the covers 12 closed compartments are created, which can also be sealed. Also a backfilling or foaming of the compartments is possible.

5 shows a further embodiment of a structural profile. It can be seen that on a top side a first cover 12a and on an underside of the profile sheet 2 a second cover 12b is arranged in the form of a cover plate. The resulting cavities 14 between the covers 12 and the profile sheet 2 For example, can be filled with a hard foam, for example polyurethane foam. 5 shows only a schematic representation of a structural profile. For better clarity, was on the presentation of the cross member 18 waived.

In the event that not all cavities 14 for example, to be filled with a foam, in particular a polyurethane foam, but for example only the cavities 14 extending between the top cover 12 and the profile sheet 2 can result, between each two of these cavities 14 a connecting element 26 , For example, a pipe, be provided through which in a cavity 14 introduced foam or the introduced filler in the next cavity to be filled 14 can get. In the 5 Not shown cover strips 22 can the front sides of the covers 12 and the profile sheet 2 cover so that the cavities 14 Are completed.

The connecting element 26 can also be designed as a coolant line, for example when using the structure profile as a solar module carrier, since there is a correlation between the temperature and the efficiency in solar modules. The waste heat can be used for heating, for example, a water storage, so that a combined photovoltaic and solar thermal use is done. For cooling are the connecting elements 26 For example, arranged so that the coolant flow serpentine or meandering shape and assigned to the side on which the solar modules are arranged, a foaming or filling of the cavities 14 is not intended, but could be in the cavities 14 done between the lower cover 12 and the profile sheet 2 be formed, in which the connecting elements 26 run. The design of the profile sheet 2 for cooling use will be explained later.

In the middle area of the 5 is shown that by different configurations of the profile sheet 2 different cavities 14 can be created. This is advantageous, for example, if pipelines or the like are to be laid in the structural profiles if the structural profiles are used, for example, in houses or boat building. While the profile sheet 2 is usually trapezoidal, is in 5 in the middle area also a rectangular profile 28 shown. Of course, all other configurations, such as triangular profiles or zigzag profiles, conceivable. The rectangular profile can serve for example for receiving a reinforcing element or connecting element, for example in a multi-hulled boat for receiving a bridge construction.

The structural profiles shown in the various embodiments are, as already stated, very flexible. In particular, by the different choice of cross sections of the profile sheet 2 , as in 5 By way of example, structural profiles can also be produced in which at the top and / or the bottom of the profile sheet 2 a cover 12 in the form of a cover plate is to be arranged, which does not form a flat surface. In particular, curved and rounded structural profiles can be produced, which is advantageous in particular when used as a ship's hull. Of course, such structure profiles can also be used in all other fields of application.

6a shows another structure profile according to an embodiment of the present invention. Here, too, was on the presentation of the cross member 18 omitted for better clarity. It can be seen again that at the top and the bottom of the profile sheet 2 in each case a cover plate is arranged. In particular, the upper cover plate as a cover 12 has hole grid 30 on, which can fulfill different functions. The holes may be used to pass, for example, hard foam into the cavities under the cover sheet 14 to lead them to fill out. Alternatively, the holes can also be used to arrange other objects or further structural elements by means of fastening elements to each other. Are in the raises 16 Also provided holes, these are preferably corresponding to the hole pattern of the cover 12 designed so that a screwing or riveting can be done with simultaneous correct alignment of the components to each other.

6b shows a detail view of a section of an embodiment of a cover 12 each between two elevations 16 arranged beads 13 , The beads 13 serve to increase the rigidity and stability of the cover 12 , Alternative to the beads 13 may also be provided openings through which the cavity 14 made accessible. For example, when using the structural profile as a floor, the cavity 14 be used as a storage space for items.

In the 7 is another embodiment of the Strukturpaneels 1 with the profile sheet 2 shown, which is angled in a trapezoidal shape, being on the flattened elevation 16 So on the top of the profile sheet 2 a heat-insulating layer 32 is applied. In the spaces between the elevations 16 and the basic sections 160 is a pipeline 34 laid, through which a heat transfer medium can be passed. The pipeline 34 is meandering in the illustrated embodiment, so that a large-scale cooling or heating of the structural profile can be done when on the top and / or bottom cover 12 is applied. Between the raises 16 and the covers 12 is advantageously the heat-insulating layer 32 applied, so on the profile top to achieve a slow heat release when used as a floor element with integrated heating. If the structural profile is used as underfloor heating element, the modular design is the pipeline 34 preferably within the circumference of the profile sheet 2 relocated, leaving the pipeline 34 does not protrude beyond the structure profile on the transverse sides. Connection elements may be present in order to allow a connection of several structural profiles with each other, so that a large-area installation of underfloor heating can take place in the plug-in method. Alternatively or additionally, the cover 12 applied on the top only after the laying of the structural profile and the insertion of a heater or cooling. The crossbeams 18 serve as a guide and as a support and increase stability, also can the cross member 18 with bushings 19 for the pipeline 34 be provided or as feedthroughs for the pipeline 34 or different media are used.

In the 8a and 8b For example, in an upper and lower side view, an example of use of the structural profile is shown as a cooling system, with one in FIG 8a not shown cover 12 only at the top of the profile sheet 2 is arranged. The upwardly open channels between two elevations 16 passing through the flanks 6 and the respective basic section 160 can be formed by fasteners 26 be connected to each other, so that in an inclined arrangement penetrating water through the connecting element 26 to the next, closed down and open at the top, by a cover, not shown 12 passed closed channel. Again, the water runs meandering, the breakthrough to the other channel can be done by pipes, cross member sections or welded profiles. For example, gravity causes the water to run downwards and can be directed to another structural profile, which is not shown. In the in 8a shown right flank 6 is an inlet 36 educated; a correspondingly arranged outlet 38 is at a lower end of the Structural profile arranged and formed for example as a pin, which in an inlet 36 a structure profile arranged adjacent to this can be introduced. An overlap section 40 is formed at the lower end of the structural profile, so that a tile-like laying of several structural profiles is possible. This overlap area 40 can be provided with a breadboard, which is designed to correspond to a hole pattern in a subsequent structure profile, so that they aligned and riveted to one another, welded or glued or optionally can be screwed.

In the respective connecting element 26 or breakthrough between the channels, a float of a certain weight can be used, closing the channels until a certain fill level is reached. Thus, not all channels must be completely filled. The structural profile formed in this way can be used, for example, as a carrier for solar elements with integrated cooling.

The angle of the flanks 6 can be selected according to the applied slope of the structural profile so that one side is substantially horizontal, so that at a low flow rate a large surface is wetted, so that a high heat output can be achieved.

In the 9 is shown a schematic detail view of an embodiment of the invention, in which the cross member 18 is designed as a U-profile with legs a and a base b. This makes it possible that the profiled sheet, not shown 2 as it is in the 1 and 2 is shown, both at a lower portion with the base b, see also 2 , as well as at the increase 16 can be fixed well over the thighs a. The fixation can be done for example by gluing or riveting, the configuration as a U-profile with legs allows a large contact surface of the base b on the lower portion or the leg a below the increase 16 , so that a large-area bonding is advantageous. In a corresponding hole pattern a simple riveting is possible, for example, on the legs a and the base b of the U-shaped cross member 18 , Alternatively, the cross member 18 be designed as another hollow profile or a solid profile.

The 10 shows a profile sheet 2 with additional recesses 8th both in the flanks 6 as well as in the raises 16 , The additional recesses 8th can be punched out and bent inwards, so that punched edges protrude inwards, so that they act as a foam channel and reinforcement and an additional anchorage when filled with a filler. The additional recesses 8th serve together with the inwardly bent flanks or sheet metal sections both the weight savings and the stiffening.

In the 11 an embodiment of the structure profile is shown. 11 shows a rigid inflatable boat, the bottom of the profile sheet 2 with corresponding cross members 18 is constructed. The flanks 6 and raises 16 extend in the width of the boat, the cross member 18 over its length, essentially from the bow to the stern. At the side edges of the structural profile is in each case a float 42 arranged, which gives the boat buoyancy in the water. That between the floats 42 arranged structural profile can on a top a cover 12 exhibit. The same is possible for the bottom. At the side edges of the profile sheet at the bow and stern 2 For example, further supporting structures, for example a holding device for a motor, can be arranged.

In the in the 12a to 12c shown example of an embodiment is the structure profile 1 each used as a part or wall of a fuselage of a catamaran. The wall is arranged substantially vertically to the water surface, whereby the flanks 6 and raises 16 of the profile sheet 2 according to the vertical direction and the cross member 18 extend substantially in a horizontal direction from the bow to the stern of a fuselage. At a lower side edge of the fuselage wall or the structural profile is at least one float 42 arranged, which gives the hull and / or catamaran in the water buoyant. The float 42 has a shape adapted to the hull and seals its bottom completely. Between two hulls is a structural structure 44 arranged, which is supported with one end on a hull, so that a catamaran is formed. The definition of the structure of the structure 44 on a fuselage will be explained later. The structure of the structure 44 is preferably a truss structure on which a cabin or cabin 46 can be arranged. The cabin 46 may also consist of side walls and / or ceilings, each of which is constructed from a structural profile. A roof construction 48 the cabin 46 is made up of a structural profile according to the invention, wherein for the operation of a photovoltaic and solar thermal system, the profile sheet for cooling and, consequently, to increase the efficiency of the systems in the first instance preferably flows through water. The catamaran can be made entirely of aluminum. Alternatively, the float can 42 and / or the hull, for example, the area of the hull in the water in the floating state of the catamaran, completely or partially constructed of a water-repellent plastic, for example polyethylene. Preferably, all components of the catamaran constructed of aluminum thus do not come into contact with the ambient water. This makes it possible that the particular arranged in the water components of the catamaran, for example, by corrosion or other environmental influences in the water, belspielsweise as a result of an electrolysis effect, are less affected. In the 12a to 12c are not shown all the covers of the profile sheet for reasons of clarity; the structure profiles 1 attached to the float 42 are arranged, advantageously have covers.

The 13a and 13b each show a detailed view of a fuselage of a catamaran in the area of the supporting structure 44 , The hull consists of an inner and an outer side wall, each constructed as a structural profile and connected to each other at the bow and stern. The structure of the structure 44 is exemplary only to the inner side wall of the fuselage in the area of a rectangular profile 28 of the profile sheet 2 set along the flanks 6 from a first side edge to a second, opposite side edge of the profile sheet 2 extends. In particular, a suspension or insertion of the supporting structure 44 for example with a bar in the rectangular profile 28 intended. The suspension of a supporting structure 44 can be used both on a profile sheet 2 trained inner and / or outer wall of the fuselage. After attaching the supporting structure, this extends at least with a beam thus along the elevations 16 and across the crossbeams 18 of the profile sheet 2 , Preferably, the structural structure 44 fixed on both fuselage walls or structural profiles. There may also be several structural structures 44 be suspended next to each other, leaving a number of structural structures 44 for example, to carry a cabin 46 are arranged between two hulls. In addition, the structural structures 44 be fixed on the front side of a hull, so that, for example, a trimaran or other bridge construction is created.

In the 13a is also in an area of the fuselage wall or profile sheet 2 an example of a cover 12 arranged, extending from a lower side edge, to a float 42 is arranged, extending to an upper side edge and over a certain length range of the fuselage or in the transverse direction of the structural profile. The tip or the bow of the fuselage may also consist of an overlapping portion of the profile sheet 2 be shaped. For optimum water displacement, this area is essentially tapered.
