Description

Die Erfindung betrifft ein schwer brennbares Flächenelement für den Schiffbau, insbesondere Decken- oder Wandelement für Schiffe oder künstliche Inseln für die Offshore-Gewinnungstechnik, nach dem Oberbegriff des Anspruchs 1.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, according to the preamble of claim 1.

Ein Flächenelement dieser Art ist aus GB-A-1 190 033 bekannt.A surface element of this type is known from GB-A-1 190 033.

Des weiteren ist aus US-A-2 063 115 ein Flächenelement bekannt, bei dem ein unter Bildung aneinander gereihter, querschnittlich dreieckiger Kammern profiliertes Blech beidseits mit Wandplatten beplankt ist. Die Kammern sind hierbei mit feuerfestem Material gefüllt.Furthermore, a surface element is known from US-A-2 063 115, in which a sheet metal profiled to form lined up, cross-sectionally triangular chambers is covered with wall panels on both sides. The chambers are filled with refractory material.

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 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; 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 similar 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 es 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 it forms a compact and yet very light component which does not have the disadvantageous thermal bridges.

Diese Aufgabe wird bei einem gattungsgemässen Flächenelement durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved in a generic surface element by the characterizing features of claim 1.

In die Kammern des Flächenelementes nach der Erfindung ist also ein Dübelprofil aus schwer brennbarem Werkstoff einschiebbar, wobei solche Dübelprofile nur in einzelne, für den Zusammenbau nötige Kammern eingeschoben und mit zugehörigen Stiften oder Schrauben für die nicht brennbaren Wandplatten verbunden sind. Die übrigen Kammern können mit Brandschutzmatten ausgefüllt werden. Die Dübelprofile dienen als Anker für beidseits des Leichtmetallprofile verlaufende, nicht brennbare Wandplatten. Diese sind mit den Dübelprofilen durch Metallstifte, Nägel oder Schrauben verbunden, ohne dass sich hier Wärmebrücken bilden könnten.A dowel profile made of flame-retardant material can thus be inserted into the chambers of the surface element according to the invention, such dowel profiles being inserted only into individual chambers required for assembly and connected with associated pins or screws for the non-combustible wall panels. The other chambers can be filled with fire protection mats. The dowel profiles serve as anchors for non-flammable wall panels running on both sides of the light metal profile. These are 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 nicht brennbaren Wandplatten glatte und ebene Aussenflächen entstehen.Thanks to these measures, shipbuilding walls are created that are insulated against fire and have considerably 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 level exterior surfaces are created when the non-combustible wall panels are applied.

Derartige Flächenelemente können problemlos für Aufbauten und Wohnmodule von Bohrinseln verwendet werden, aber auch für Schiffseinbauten. Insbesondere bei Bohrinseln 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. The safety regulations are very strict, especially for drilling rigs. 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 on 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.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.

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.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.

Eine in Fig. 1 wiedergegebene Innenwand 10 eines nicht weiter dargestellten Schiffes oder einer Bohrinsel weist beidseits eines Kernes aus Leichtmetallprofilen 11 -- einer jeweiligen Querschnittslänge a von hier 600 mm und einer Querschnittsbreite b von 45 mm -- feuerhemmende Wandplatten 12 einer Dicke e von 12 mm aus Fibersilikat od. dgl. Werkstoff mit einem Gewicht von etwa 10,5 kg je Plattenquadratmeter auf.An inner wall 10 shown in FIG. 1 of a ship or an oil rig not shown further has a core of light metal profiles 11 on both sides - a respective cross-sectional length a of here 600 mm and a cross-sectional width b of 45 mm - fire-retardant wall panels 12 with a thickness e of 12 mm made of fiber silicate or the like. Material with a weight of about 10.5 kg per panel square meter.

Bei 35 ist eine Schweißnaht zwischen einer Rinnenkante 36 eines Leichtmetallprofiles 11 und der angefasten Längskante 37 des anstoßenden Leichtmetallprofiles 11 ersichtlich.In Fig. 1, a joint between two wall panels 15 can be seen at 14, which requires the use of a pair of screws 31. At 35, a weld seam between a channel edge 36 of a light metal profile 11 and the chamfered longitudinal edge 37 of the abutting light metal profile 11 can be seen.

In die nach Einschub der Dübelprofile 30 verbleibenden Wandhohlräume sind nichtbrennbare Mineralwollmatten 40 eingesetzt.Non-combustible mineral wool mats 40 are inserted into the wall cavities remaining after insertion of the dowel profiles 30.

Beim Leichtmetallprofil 1 la der Fig. 4 sind die dem Schlitz 16 der Profilplatte 15 benachbarten Stege 17a, 18a querschnittlich zueinander gestuft und bilden zwei Anlageschultern 42 sowie eine dazu versetzte Rückwand 43; auch hier ist die Querschnittsmittelachse Mi bzw. M2 Symmetrieachse des Kammerquerschnitts.. When light metal profile 1 la of Figure 4, the slot 16 of the profile plate 15 adjacent webs 17a, 18 a cross-sectionally mutually stepped and form two abutment shoulders 42, and a rear wall 43 offset therefrom; here too the cross-sectional central axis M i or M 2 is the axis of symmetry of the chamber cross-section.

Die -- der sich an der Profilplatte 15 öffnenden Kammer 25a -- benachbarte Kammer 26a wird von einem T-förmigen Verlängerungsabschnitt 45 des Steges 18a einerseits sowie einer seitlichen Anformung 46 an den Steg 18a begrenzt; diese Anformung 46 bildet jenseits der Symmetrieachse M2 die andere Wand 26a, deren Rückwand 43a zur Profilplatte 15 in einem Abstand t von 16 mm steht. Dabei bildet der Kopfteil 47 des T-artigen Verlängerungsabschnittes 45 mit einem fluchtenden Teil 48 der Anformung 46 eine Anlagefläche in einem der Profilbreite b entsprechenden Abstand zur Profilplatte 15.The - of the opening on the profiled plate 15. Chamber 25a - adjacent chamber 26 a is of a T-shaped extension portion 45 of the web 18a on the one hand as well as a lateral conformation 46 on the web 18 a limited; beyond the axis of symmetry M 2, this projection 46 forms the other wall 26 a , the rear wall 43 a of which is at a distance t of 16 mm from the profile plate 15. The head part 47 of the T-like extension section 45 forms an abutment surface with an aligned part 48 of the molding 46 at a distance from the profile plate 15 corresponding to the profile width b.

Im übrigen sind die Abstände si bzw. s2 der Profilenden 36 bzw. 37 von den nächstliegenden Mittelachsen M2 bzw. M1 ungleich, nämlich etwa 50 mm bzw. 110 mm.Otherwise, the distances si and s 2 of the profile ends 36 and 37 from the nearest central axes M 2 and M 1 are unequal, namely approximately 50 mm and 110 mm.

Jedes Leichtmetallprofil 11 besteht querschnittlich aus einer Profilplatte 15 mit --hier drei -- Längsschlitzen 16 der Breite i (beispielsweise 30 mm) und beidseits jenes Längsschlitzes 16 rechtwinklig angeformten Stegen 17,18, die unter Bestimmung jener Querschnittsbreite b durch eine parallel zur Profilplatte 15 verlaufende Querwand 20 verbunden sind. Letztere kragt über den einen Steg 18 hinaus und fluchtet mit einem Schenkel 22 eines dritten Steges 19; Schenkel 22 und die freie Kante 21 der Querwand 20 begrenzen ihrerseits einen Schlitz 23 der Breite i. Die Breiten der Schlitze 16 und 23 sind hier gleich bemessen, können jedoch auch differieren.Each light metal profile 11 has a cross-section of a profile plate 15 with - here three - longitudinal slots 16 of width i (for example 30 mm) and on both sides of that longitudinal slot 16 rectangularly shaped webs 17, 18, which are determined by determining the cross-sectional width b by a parallel to the profile plate 15 extending transverse wall 20 are connected. The latter protrudes beyond one web 18 and is aligned with one leg 22 of a third web 19; Leg 22 and the free edge 21 of the transverse wall 20 in turn limit a slot 23 of width i. The widths of the slots 16 and 23 are dimensioned the same here, but can also differ.

Die Stege 17 bis 19 begrenzen zwei einander benachbarte Kammern 25,26 mit zueinander gegenläufigen Zugangsöffnungen in Form der Schlitze 16 und 23. Der Abstand h der Querschnittsmittelachsen M1 und M2 benachbarter Kammern 25,26 mißt 56 mm, der Abstand f zwischen den Querschnittsmittelachsen M1 bzw. M2 gleichgerichteter Kammern 25 bzw. 26 mißt 200 mm. Die lichte Kammerbreite m beträgt hier etwa 52 mm, die Kammertiefe n 37 mm.The webs 17 to 19 delimit two adjacent chambers 25, 26 with mutually opposite access openings in the form of the slots 16 and 23. The distance h between the cross-sectional central axes M 1 and M 2 of adjacent chambers 25, 26 measures 56 mm, the distance f between the cross-sectional central axes M 1 and M 2 rectified chambers 25 and 26 measure 200 mm. The clear chamber width m is about 52 mm, the chamber depth n 37 mm.

In den lichten Kammerquerschnitt ragen von jedem angrenzenden Steg 17 und 18 bzw. 18 und 19 in Abstand q1 (beispielsweise 6 mm) von der jeweiligen Kammerrückwand 20 bzw. 15 miteinander fluchtende Rippen 28 ab, die mit der Kammerfrontwand 15 bzw. 20, 22 (Abstand q2 = 27 mm) ihrer Kammer 26 bzw. 27 eine Einschubbahn für ein Dübelprofil 30 aus Fibersilikat begrenzen; letzteres ist von Schrauben 31 durchsetzt, welche durch die Wandplatte 12 sowie die Schlitze 16, 23 greifen. 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, the ribs 28 and 20, 22 respectively (Distance q 2 = 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 central cross-sectional axes M 1 and M 2 is so large - here: 100 mm - that the counter-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 M 2 . 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 or e 1 of the wall panels 12.

Panel according to Claim 1, characterized in that in each case two chambers (25, 26) opening in opposite directions are adjacent and are defined by three webs (17, 18, 19) which are integrally formed on a plate (15) and of which two (18, 19), at their end remote from the plate (15), through integrally formed parts (21, 22) in alignment with one another, have an L-shaped cross-section and form a slot (23), while projecting lengths (15a) of the plate (15) form the undercut of the chambers (25) open to the plate (15).
3. Panel according to Claim 2, characterized in that ribs (28) are integrally formed on the webs (17, 18, 19), which ribs (28), with the rear walls (20, 20a) of the chambers (25, 26) and/or with the projecting lengths (15a) or integrally formed parts (21, 22) of the chambers (25, 26), form push-in paths in the chambers (25, 26).
4. Panel according to Claim 1, characterized in that in each case two chambers (25a, 26a) opening in opposite directions are adjacent and are defined by three webs (17a, 18a, 19a), of which two webs (17a, 18a) are integrally formed on a plate (15) and one web (19a) projects from one of the other two webs.
5. Panel according to Claim 4, characterized in that the two webs (17a, 18a) integrally formed on the plate (15) are connected by bearing shoulders (42) of the chambers (25a, 26a) being formed and are also provided with an extension portion (45) which is T-shaped in cross-section and opposite which is a lateral integrally formed part (46), T-shaped in turn, of the third web (19a), which likewise forms a bearing shoulder (42).
6. Panel according to Claim 1, characterized in that the chambers (26b) opening away from a plate (15) are formed by channel sections (50) integrally formed separately on the plate (15) and are joined to the latter via struts (51).
7. Panel according to one of Claims 4 to 6, characterized in that a channel (43, 43a, 43b) is integrally formed in the rear walls of the chambers (25a, 26a; 25b, 26b).
8. Panel according to one of Claims 1 to 7, characterized in that the cross-section of the chambers (25, 26; 25a, 26a; 25b, 26b) or the cross-section of the push-in path determined by the distance (qi, q2) of the ribs (28) from the rear walls (20, 20a) or the projecting lengths (15a) or the integrally formed parts (21, 22) is filled by the plug section (30), which in particular is made of fibre silicate.
