Description

Die Erfindung betrifft ein schwer brennbares Flächenelement für den Schiffsbau, insbesondere ein Decken- oder Wand­element für Schiffe oder künstliche Inseln für die Offshore-­Gewinnungstechnik, mit einem Metallkern und an diesem durch Stifte od. dgl. festgelegte Brandschutzmatten od. dgl.The invention relates to a flame-retardant surface element for shipbuilding, in particular a ceiling or wall element for ships or artificial islands for offshore extraction technology, with a metal core and fire protection mats or the like fixed to it by pins or the like.

Schiffbauliche Wände sind im allgemeinen tragende Verbände des Schiffes. Sie bestehen aus Blechen mit regelmäßigen Versteifungen, die aufgeschweißt oder als Sicken ausgebil­det sind. Alle außenliegenden Wände werden im Schiffsbau gegen Wärme und Kälte isoliert. So besteht beispielsweise eine auf dem Markt befindliche Schiffswand aus einer Stahl­platte mit daran angeschweißten L-Profilen als Versteifun­gen. Sowohl die L-förmigen Profile als auch die Stahlplat­te selbst sind durch Brandschutzmatten, beispielsweise der Handelsmarke ISOVER, belegt; die Brandschutzmatten sind durch dünne Befestigungsstifte gehalten. Die so aufgebrach­te Mineralwolle muß dann noch mit Planen, Dekorwänden od. dgl. Schutzflächen versehen werden. Als nachteilig hat sich der gesamte Aufbau mit seiner leicht zu beschädigenden Außenseite erwiesen. Außerdem bilden die Befestigungsstif­te unerwünschte Wärmebrücken.Shipbuilding walls are generally the supporting structures of the ship. They consist of sheets with regular stiffeners that are welded on or designed as beads. All exterior walls are insulated against heat and cold in shipbuilding. For example, a ship's wall on the market consists of a steel plate with welded-on L-profiles as stiffeners. Both the L-shaped profiles and the steel plate itself are covered with fire protection mats, for example the ISOVER brand; the fire protection mats are held by thin fastening pins. The mineral wool applied in this way must then be provided with tarpaulins, decorative walls or the like. Protective surfaces. The entire structure with its easily damaged outside has proven to be disadvantageous. In addition, the mounting pins form undesirable thermal bridges.

Angesichts dieser Gegebenheiten hat sich der Erfinder das Ziel gesetzt, ein schwer brennbares Flächenelement der eingangs erwähnten Art so auszugestalten, daß letzteres ein kompaktes und dennoch sehr leichtes Bauelement bildet, dem die nachteiligen Wärmebrücken fehlen.In view of these circumstances, the inventor has set himself the goal of designing a flame-retardant surface element of the type mentioned at the outset in such a way that the latter forms a compact, yet very light component which lacks the disadvantageous thermal bridges.

Zur Lösung dieser Aufgabe führt, daß der Metallkern von wenigstens einem Leichtmetallprofil gebildet ist, wel­ches an einer Profilplatte in Abstand zueinander Aus­nehmungen als Öffnungen von Kammern in Form hinterschnit­tener Nuten aufweist sowie nahe jeder Kammer wenigstens eine sich zur Gegenseite hin öffnende andere hinterschnit­tene Kammer. Darüber hinaus sollen mehrere Leichtmetall­profile so angeordnet sein, daß die Profilplatten miteinan­der fluchten und deren Kammern zueinander parallel ver­laufen.To achieve this object, the metal core is formed by at least one light metal profile which has recesses on a profile plate at a distance from one another as openings of chambers in the form of undercut grooves, and at least one other undercut chamber opening towards the opposite side near each chamber. In addition, several light metal profiles should be arranged so that the profile plates are aligned with one another and their chambers run parallel to one another.

In die Kammern werden Dübelprofile aus schwer brennbarem Werkstoff, bevorzugt aus Fibersilikat, eingeführt und dienen als Anker für beidseits der Profilplatte verlaufen­de Feuerschutzplatten. Diese können mit den Dübelprofilen durch Metallstifte, Nägel oder Schrauben verbunden sein, ohne daß sich hier Wärmebrücken bilden könnten.Dowel profiles made of flame-retardant material, preferably made of fiber silicate, are inserted into the chambers and serve as anchors for fire protection panels running on both sides of the profile panel. These can be connected to the dowel profiles by metal pins, nails or screws without thermal bridges being able to form here.

Dank dieser Maßgaben entstehen schiffbauliche Wände, die gegen Feuer isoliert sind und erheblich kleinere Bauhöhen haben als vergleichbare Wände bekannter Art mit gleichen Festigkeitswerten - dies führt zu einem erheblichen Raum­gewinn. Darüber hinaus sind die erfindungsgemäßen Flächen­elemente erheblich leichter als die Flächenelemente nach dem Stande der Technik. Sie lassen sich auch sehr schnell montieren, was zu einer Reduzierung der Lohnkosten führt. Als weiterer Vorteil ist anzusehen, daß schon beim Auf­bringen der Feuerschutzplatten glatte und ebene Außen­flächen entstehen.Thanks to these measures, shipbuilding walls are created that are insulated against fire and have significantly smaller heights than comparable walls of a known type with the same strength values - this leads to a considerable gain in space. In addition, the surface elements according to the invention are considerably lighter than the surface elements according to the prior art. They can also be assembled very quickly, which leads to a reduction in labor costs. Another advantage is that smooth and flat outer surfaces are created when the fire protection panels are applied.

Derartige Flächenelemente können problemlos für Aufbau­ten und Wohnmodule von Bohrinseln verwendet werden, aber auch für Schiffseinbauten. Insbesondere bei Bohr­ inseln sind die Sicherheitsvorschriften sehr streng. Bei­spielsweise muß eine Wand bei einer Außentemperatur von 1150° C eine Stunde die volle statische Last übernehmen und darf auf der dem Feuer abgewandten Seite nicht mehr als 140° C am Metallkern messen. Da aber auch Feuer auf der Innenseite in den Räumen entstehen kann, gelten in der umgekehrten Richtung 970° C für 60 Minuten. Diesen Vorgaben wird das erfindungsgemäße Flächenelement gerecht und bietet darüber hinaus die bereits beschriebenen Vor­züge an.Such surface elements can easily be used for structures and residential modules of drilling rigs, but also for ship installations. Especially with Bohr islands, the safety regulations are very strict. For example, a wall with an outside temperature of 1150 ° C must take over the full static load for one hour and must not measure more than 140 ° C at the metal core on the side facing away from the fire. However, since there can also be fire on the inside of the rooms, 970 ° C in the opposite direction applies for 60 minutes. The surface element according to the invention meets these requirements and also offers the advantages already described.

Nach einem weiteren Merkmal der Erfindung ist der Metall­kern bzw. das Leichtmetallprofil mit jeweils zwei gegen­läufig sich öffnenden Kammern versehen, die einander be­nachbart sind und von drei an die Profilplatte angeformten Stegen begrenzt sind, von denen zwei an ihren der Pro­filplatte fernen Ende durch miteinander fluchtende An­formungen einen L-förmigen Querschnitt anbieten. Es ent­steht so ein äußerst stabiler Metallkern, welcher den Ab­stand der Feuerschutzplatten fixiert und als Leichtmetall-­Strangprofil auch in einfacher Weise herzustellen ist. Weitere Ausgestaltungen des Leichtmetallprofiles sind in den Unteransprüchen beschrieben und haben gemeinsam, daß Einschubbahnen für schwer entflammbare Dübelprofile entstehen, die von beiden Profilseiten zugänglich sind und Nägel, Schrauben oder entsprechende Verbindungselemen­te aufnehmen können, ohne daß dadurch Temperaturbrücken entstehen würden.According to a further feature of the invention, the metal core or the light metal profile is provided with two oppositely opening chambers, which are adjacent to one another and are delimited by three webs molded onto the profile plate, two of which at their end remote from the profile plate by means of alignments which are aligned with one another offer an L-shaped cross section. The result is an extremely stable metal core, which fixes the distance between the fire protection plates and can also be easily manufactured as a light metal extruded profile. Further refinements of the light metal profile are described in the subclaims and have in common that insertion tracks are created for flame-retardant dowel profiles which are accessible from both profile sides and can accommodate nails, screws or corresponding connecting elements without this resulting in temperature bridges.

Bei einem besonderen Ausführungsbeispiel ist dafür ge­sorgt, daß das eingeschobene Dübelprofil in Abstand zur Kammerrückwand steht, so daß die freien Enden der Nägel oder Schrauben in einem Hohlraum enden und den Leicht­metallkern nicht berühren. Gleichem Effekt dient die Maßgabe, in der Kammerrückwand eine Rinne vorzusehen.In a special embodiment it is ensured that the inserted dowel profile is at a distance from the rear wall of the chamber, so that the free ends of the nails or screws end in a cavity and do not touch the light metal core. The same effect is provided by the requirement to provide a channel in the rear wall of the chamber.

Die Breite des erfindungsgemäßen Flächenelementes kann nach einem anderen Merkmal der Erfindung dadurch variiert werden, daß man zwischen ein die Kammer bilden­des Rinnenprofil und die Profilplatte einen Steg ein­fügt, dessen Länge gewählt werden kann.According to another feature of the invention, the width of the surface element according to the invention can be varied by inserting a web between a channel profile forming the chamber and the profile plate, the length of which can be selected.

Als günstig hat es sich auch erwiesen, die hinterschnitte­nen Kammern für das Einsetzen an sich bekannter Klemm­stücke zu verwenden, welche dem Anschluß von Stahlteilen an den Leichtmetallkern dienen.It has also proven to be advantageous to use the undercut chambers for inserting known clamping pieces, which are used to connect steel parts to the light metal core.

Die Enden 32 der Schraube 31 ragen in einen durch jene Rippen 28 bestimmten End­raum ein.In the clear chamber cross-section project from each adjacent web 17 and 18 or 18 and 19 at a distance q 1 (for example 6 mm) from the respective chamber rear wall 20 or 15, ribs 28 aligned with one another, which are connected to the chamber front wall 15 or 20, 22 ( Distance q₂ = 27 mm) of their chamber 26 or 27 limit an insertion path for an anchor profile 30 made of fiber silicate; the latter is penetrated by screws 31 which engage through the wall plate 12 and the slots 16, 23. The ends 32 of the screw 31 protrude into an end space defined by those ribs 28.

Die eine Kammer 25b am Schlitz 16 der Profilplatte 15 in Fig. 5 entspricht in ihrem Querschnitt etwa der Kammer 25a der Fig. 4, wobei die Kammerrückwand 43e hier halbkreisförmigen Querschnittes ist. Bei diesem Ausführungsbeispiel ist der Abstand h₁ zwischen den Querschnittsmittelachsen M₁ und M₂ so groß -- hier: 100 mm --, daß die gegenläufig sich öffnende Kammer 26b nicht von Begrenzungswänden der anderen Kammer 25b ge­bildet werden kann; vielmehr ist hier ein Rinnenprofil 50 als Kammerbegrenzung vorgesehen, welches durch einen in die Querschnittsmittelachse M₂ fallenden Stiel 51 an die Innenfläche der Profilplatte 15 angeformt ist. Die Kontur der Kammer 26b enspricht jener der Kammer 25b, wobei auch hier angeformte Teile 47, 48 miteinander fluchten und den Schlitz 23 begrenzen. Die Profilbreite b beträgt hier 70 mm bei unterschiedlicher Dicke e bzw. e₁ der Wandplatten 12.The cross section of the one chamber 25 b at the slot 16 of the profile plate 15 in FIG. 5 corresponds approximately to the chamber 25 a of FIG. 4, the chamber rear wall 43 e here being a semicircular cross section. In this embodiment, the distance h 1 between the cross-sectional central axes M 1 and M 2 is so large - here: 100 mm - that the oppositely opening chamber 26 b cannot be formed by boundary walls of the other chamber 25 b ; rather, a channel profile 50 is provided here as a chamber boundary, which is formed on the inner surface of the profile plate 15 by a stem 51 falling into the central cross-sectional axis M₂. The contour of the chamber 26 b corresponds to that of the chamber 25 b , here also molded parts 47, 48 are aligned with one another and delimit the slot 23. The profile width b here is 70 mm with different thicknesses e and e 1 of the wall panels 12.

Die Kammer 26b nimmt ein plattenartiges Klemmstück 53 parallelo­grammartigen Umrisses auf, dessen Breite c geringer ist als die Breite i des Schlitzes 23 und das dank dieser Maßgabe in die Kammer 26b eingeführt und darin gedreht werden kann, bis die in Fig. 7 dargestellte Endlage er­reicht ist, in welcher eine Schraube 54 festgezogen wer­den kann, um einen Stahlanschluß 60 am Leichtmetallprofil 11b festzulegen.The chamber 26 b receives a plate-like clamping piece 53 parallelogram-like outline, the width c of which is less than the width i of the slot 23 and which, thanks to this provision, can be inserted into the chamber 26 b and rotated therein until the end position shown in FIG. 7 is reached, in which a screw 54 can be tightened to fix a steel connection 60 to the light metal profile 11 b .
