Definitions

  • Structural sheet metal profile for a supporting structure, supporting structure and method for producing it
  • the invention relates to a structural sheet metal profile for a support structure and such a support structure. Furthermore, a boat hull with the supporting structure, a catamaran with the supporting structure and a method for producing a supporting structure as well as a method for producing a catamaran are provided.
  • DE 10 2011 111 530 B3 shows such a structural sheet metal profile that can be used in particular in the side hulls of a catamaran.
  • the structural sheet metal profiles are each formed by a folded profile sheet with recesses in their flanks, whereby parallel cross struts are subsequently placed through the recesses, and cover elements are then placed and fastened on the top and bottom. This means that a lightweight yet rigid design in sandwich construction is possible.
  • DE 20 2009 011 263 U1 shows a device for protecting a ship's hull against the influences of shock waves, with a substantially flat element being provided on the outside of the ship's hull
  • PCT Bre/kl 05/17/2023 is designed to be flexible and has such deformability that it is able to at least partially destroy the energy transmitted by a shock wave before the shock wave reaches the ship's hull.
  • the flat element can be elastic or plastic and serve to form an outer skin.
  • the invention is based on the object of creating a structural sheet metal profile for a support structure, such a support structure, a boat hull and methods for manufacturing which enable quick and precise production with low weight.
  • the support structure according to the invention and/or the catamaran according to the invention can in particular be produced by a method according to the invention.
  • the catamaran can in particular be a Swath catamaran (Small Waterplane Area Twin Hull - catamaran) or a catamaran with a double hull with a small waterline area.
  • a structural sheet metal profile is thus created, which is designed and intended in particular to be placed between two frames.
  • the structural sheet metal profile has a folded profile sheet, which is formed by folding a perforated starting sheet and preferably has parallel elevations and depressions formed between them, which thus enable high rigidity and bending strength. Furthermore, an upper cover element is placed on the profiled sheet.
  • the two frames and corresponding support surfaces of the profiled sheet for resting on the two spaced frames run in a transverse direction, in particular parallel.
  • the transverse direction can also extend partially or completely in the vertical direction, corresponding to the course of the frames, which can be angled, for example.
  • no continuous struts are provided, which run continuously through the structural sheet metal profile in the transverse direction and reinforce the folded sheet metal profile.
  • no struts that extend at least partially in the transverse direction can be provided, preferably without any reinforcing struts.
  • stiffening can take place without the complex insertion of continuous struts through recesses in several elevations.
  • recesses are formed in several, preferably all, elevations and struts are placed through the recesses.
  • obliquely sloping flanks can run between the elevations (20) and the depressions, in which the recesses are formed, the struts running at least partially in the transverse direction of the folded profile sheet and being inserted through the recesses of several elevations.
  • the struts run obliquely to the elevations and depressions, in particular crossing each other or as an X-formation, and are attached or attachable to the frames in their end regions, e.g. B. welded. This achieves a high level of rigidity, as a direct connection between the frames is achieved through the oblique struts, in addition to the connection through the folded sheet metal.
  • a stable and rigid structure can be formed with high manufacturing precision, in which the structural sheet metal profiles form the connection between the frames to ensure. Furthermore, a support structure is thereby formed which can advantageously be sealed over the entire surface towards the top and bottom.
  • Frames are elongated support elements, e.g. square tubes.
  • frames are understood to mean the load-bearing, in particular U-shaped, cross members which run at least in some areas in the transverse direction through the boat hull.
  • An upper cover element is placed on the top of the profiled sheet and in particular the frames, which is made of metal according to a preferred embodiment.
  • An upper cover element hole grid is formed in the upper cover element.
  • an upper profile hole grid is formed in the top of the profile sheet, which preferably corresponds to the hole pattern of the upper cover element.
  • the hole grid can be aligned so that the upper cover elements and/or the profile elements with their hole grid are placed on the two adjacent frames and the frames and the upper cover element and/or the profile element are aligned with one another with little effort, precisely and safely .
  • the frames are preferably already set up, but are initially adjustable and can therefore be aligned or adjusted by adjustment to the upper hole grid of the profile element and the upper cover element hole grid.
  • Aligning or adjusting two hole grids is understood to mean, in particular, an arrangement of the two hole grids that coincides or is concentric at least in some holes.
  • the upper cover element hole grid also has support surfaces for resting on the frames and fastening holes for fastening to the frames, that is, the upper cover element is not only fastened to the structural profile sheet with its fastening holes, but also on the adjacent or opposite frames. This support can be done directly or with an intermediate element, in particular the profiled sheet.
  • the alignment and attachment of the upper cover element and/or the profiled sheet to the frames also interacts in particular with the manufacturing method according to the invention for the support structure, as will be described further below.
  • the profile sheets have support webs with which they are placed on the frames.
  • the support webs can in particular limit the depressions formed between the elevations of the structural profile to the sides.
  • the profiled sheets can thus be placed with their side, preferably circumferential, support webs on the top of the frames, which enables quick and safe training, since the profiled sheets only have to be placed here from the top.
  • the hole pattern on the top of the profile sheets, in particular the holes in the support webs is aligned with the hole pattern on the top of the frames.
  • the frames in particular can be readjusted somewhat in the longitudinal direction of the support structure in order to achieve a match, in particular a concentric match.
  • the upper cover element is then placed and aligned with the hole pattern of the frames and the profiled sheet, so that secure fixation and fastening is subsequently possible using fasteners used. Rivets in particular can be used as fasteners, but also screws or e.g. B. plastic clips. This means that the profile sheets and cover elements can be firmly connected to the frames and thus form a unit.
  • the upper cover element is advantageously made of metal, ie as a cover plate, which is connected to the top of the profiled sheet and the top of the frames via rivets serving as fastening elements.
  • the lower cover element is advantageously made of metal, ie as a cover plate, which is fastened via rivets serving as fastening elements.
  • an insulating cover plate can also be placed as the upper and / or lower cover element, for example made of a plastic such as GRP, or wood or plywood.
  • a plastic such as GRP, or wood or plywood.
  • the cover element can in turn be attached and fixed via the hole grid, with plastic clips, for example, being able to serve as fastening elements.
  • the cover elements can also be retrofitted, e.g. B. as meter goods.
  • the upper and/or lower cover elements can, for example, also be designed in two parts, for example a layer made of sheet metal and a further layer made of a different material.
  • the two layers of the cover element preferably each have a perforated grid, in particular aligned or matching perforated grids, and can thus be connected to the profiled sheet and/or frames via common or separate fastening means.
  • the respective hole may not be continuous.
  • the structural sheet metal profile according to the invention is formed in particular by the folded profile sheet and the upper, and possibly also lower, cover element, the elements of the structural sheet metal profile thus being successively fastened to or on the frames, so that the structural sheet metal profile is completely formed on the frames.
  • No struts are required here;
  • a significant advantage of the invention is that the connection of two adjacent frames takes place in the unedged longitudinal direction of the profile sheets; This means that the upper profile hole grid in the profile sheet connects two adjacent frames in the longitudinal direction of the support structure, without the distance between the holes of the upper profile hole grid in this longitudinal direction being influenced by folds.
  • the support structure is modular and can also be extended using many identical parts to form boat hulls of different lengths or dimensions. Standardized frames and standardized profile sheets as well as cover elements and, if necessary, insulating cover elements can be used.
  • Another advantage is the high degree of automation through computer-aided production.
  • the prefabricated formation of the hole pattern in the initial sheet metal before edging enables computer-aided production;
  • Another advantage of using identical parts and, in particular, computer-aided manufacturing is that it enables easy adjustment to areas of the boat hull that are subject to different loads. Thanks to the high degree of automation and computer-aided production, topology optimization can be achieved, for example by forming topology holes in areas of the folded profile sheets that are not subject to such loads. This makes it possible to reduce weight and reduce manufacturing and operating costs.
  • the topology optimization can be adapted to the load on the various points of the support structure; so can e.g. B. in areas of a support structure that are exposed to greater stress from waves, a different topology optimization, e.g. B. with fewer recessed areas can be used than in less stressed areas. Nevertheless, standardized folded profile elements can be used, which are optimized with different topologies depending on the load.
  • the topology holes can be formed by simply cutting out; Alternatively or additionally, the topology holes can also be flanged at their edges or reinforced by bending, so that greater rigidity is achieved.
  • the transitions between the elevations and depressions in the folded profile sheets are through flanks, e.g. B. oblique flanks.
  • reinforcing elements are inserted into the folded profile sheets.
  • the reinforcing elements can be inserted from the top into the recesses of the folded profile sheets, and/or from the bottom into the elevations, for example as plug-in inserts that are inserted into suitable fastenings of the folded profile sheet.
  • the reinforcing elements can be used, for example, as reinforcing ribs, in particular trapezoidal sheets, or as wedge-shaped elements, preferably Sheet metal elements can be formed and are attached to the profiled sheet. As a result, a significant increase in rigidity can be achieved with little material and manufacturing effort. Reinforcing elements can in particular also be provided instead of the struts.
  • the construction time can be reduced while increasing the accuracy of fit.
  • the profile sheets and/or the upper and lower profile elements can be placed between exactly two adjacent frames.
  • the folded profile sheet and/or the upper cover element and/or the lower cover element can extend over more than two, in particular over three frames, i.e. cover a central frame. This means that flat surface areas in particular can also be covered with a smaller number of parts, with reduced assembly time.
  • a high degree of fitting accuracy and rapid production is achieved, in particular through the formation of perforated grids in the elements to be used, with the perforated grids having high accuracy, e.g. B. can be designed computer-aided by lasers.
  • the step of forming the profiled sheets can take place before or after the formation of the frames and before or after setting up the frames and connecting an upper and lower frame in a transverse plane.
  • the frames are first aligned parallel to one another and the profile sheets are then inserted, in particular placed from above.
  • the upper cover elements in particular cover elements, are placed at least from the top and are preferably connected to one another via the hole grids that are fitted or aligned with one another, so that the structural sheet metal profiles formed in this way securely fix the frames in their position on the one hand and connect them on the other. Further fixation is preferably carried out by the lower cover elements, which are attached to the folded profile sheets and the frames and thus increase the strength as parts of the structural sheet metal profiles.
  • the profile elements and cover elements can be placed on the frames and these parts can be adapted to one another by aligning the hole grid, so that e.g. B. the frames can be aligned slightly, especially adjusted in the longitudinal direction, in order to correspond to the hole pattern of the profile sheets and cover elements. This means that the neighboring elements align with each other.
  • the profile sheets, preferably also the cover elements connect two adjacent frames with each other, in which the hole grid of the profile sheets and the cover elements are each placed on the hole grid of both the left and right frames and thus connect them.
  • the hole grids of adjacent frames overlap each other via the hole grids of the profile sheets and cover elements and enable a secure, successive alignment of the elements during production.
  • the profile sheets and cover elements can thus be successively placed, aligned and fixed between two frames in order to subsequently attach and align the subsequent structural profiles on the frames and the adjacent frames.
  • the underside of the frames and profile sheets is also advantageously reinforced by lower cover elements.
  • a hole grid is therefore provided on the underside of the profile sheets and the underside of the frames, onto which the lower cover element with its lower cover hole grid is placed and aligned. Fixation here is advantageously carried out via fastening means, e.g. B. Rivet.
  • the air volumes formed in this way can in principle also be formed with a vacuum and/or a protective gas.
  • the support structure designed in this way or the boat hull designed in this way can in particular further have lower profile pieces for inclusion in floating bodies of a catamaran, in particular Swath catamarans.
  • the lower ends of a bow-shaped support structure can be z.
  • vertically extending profile pieces can be formed, which are inserted into suitable, matching receptacles of the floating bodies.
  • Aluminum or an aluminum alloy is advantageously used as the material for the frames and profile sheets, and possibly also the cover elements, in particular a seawater-resistant aluminum alloy such as AIMg3 or AIMg4.5.
  • a seawater-resistant aluminum alloy such as AIMg3 or AIMg4.5.
  • Such an aluminum material is very light with high rigidity, so that a low weight is achieved with high seawater resistance.
  • the aluminum material also enables the process steps of cutting and edging with little technical effort.
  • B. the rivet holes in the flanks, as well as topology holes, can be formed by laser cutting.
  • the cover elements can also extend over several frames, so that fewer joints are required.
  • module-based training allows for equal parts and in particular specially adapted parts in the shaped areas of the boat hull.

  • B. the folded profile sheet and the cover elements can be achieved.
  • curves or radii can be designed appropriately by using the profile sheet z. B. with a rounding, further z. B. is also formed in two parts by two attached parts.
  • the profiled sheet can also be formed by folded support bars instead of with support webs, i.e. in particular with a 90° fold relative to the profiled sheet, so that the folded support web is placed on the end face against a side surface of a frame and fastened via a hole pattern.
  • the profile sheets can be folded on several sides so that they have upstands on the sides.
