Description

Die Erfindung bezieht sich auf ein Treppenhaus für mehrgeschossige Fertighäuser, wobei das Treppenhaus aus vorgefertigten Raumzellen besteht, wobei die einzelnen, übereinander zu stapelnden Raumzellen fabrikseitig vormontierte und eingebaute Treppen aufweisen, wobei in die Raumzellen Podeste eingebaut sind, zwischen denen die Treppen angeordnet sind und wobei in der Bodenplatte und/oder Deckenplatte Aussparungen eingelassen sind.The invention relates to a staircase for multi-storey prefabricated houses, the staircase consisting of prefabricated room cells, the individual cells to be stacked one above the other having factory-assembled and installed stairs, with platforms being built into the room cells, between which the stairs are arranged and where There are recesses in the base plate and / or ceiling plate.

Ein derartiges Treppenhaus für ein mehrgeschossiges Fertighaus ist aus der US-A-4 930 273 bekannt. An den übereinanderliegend angeordneten Raumzellen sind an den Boden- und Deckenplatten Aussparungen zur Bildung des Treppenhauses vorgesehen. Im Bereich der Boden- und Deckenplatten schließen sich an diese Podeste an, zwischen denen die vorgefertigten Treppen angeordnet sind.Such a staircase for a multi-storey prefabricated house is known from US-A-4 930 273. Recesses are provided on the floor and ceiling panels on the stacked room cells to form the staircase. In the area of the floor and ceiling panels, these platforms are connected, between which the prefabricated stairs are arranged.

Aus der FR-A-1 465 704 ist ein Treppenhaus bekannt, das vorgefertigte Treppen mit an Treppenwangen vormontierten Treppengeländern aufweist. Das Treppenhaus weist Zwischenpodeste auf, die als Stahlgitterkonstruktion ausgeführt sind.A staircase is known from FR-A-1 465 704, which has prefabricated stairs with stair rails preassembled on stair stringers. The staircase has intermediate platforms that are designed as a steel lattice construction.

Bei Zwischenpodesten besteht das Problem der Abstützung.With intermediate platforms there is the problem of support.

Demgemäß liegt der Erfindung die Aufgabe zugrunde, ein Treppenhaus der eingangs genannten Art vorzuschlagen, bei dem das Zwischenpodest auf einfache Weise abgestützt wird.Accordingly, the invention has for its object to propose a staircase of the type mentioned, in which the intermediate platform is supported in a simple manner.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Raumzellen eine Bodenplatte mit einem Rahmen aus Stahlprofilen, aufsteigenden Säulenelementen an den Ecken, einen oberen Deckenrahmen und stirnseitig fertig montierten Außenwandungen mit Brüstung, Fenstern, Isolierung und Brandschutz aufweisen, daß die Podeste als zwischen der Bodenplatte und der Deckenplatte einer Raumzelle angeordnete Zwischenpodeste ausgebildet sind, daß die Zwischenpodeste auf einer Seite aus zwischen den aufsteigenden Säulenelementen der Raumzellen festgelegten Querträgern und auf der anderen Seite an Querträgern gehalten sind, die sich an aufsteigenden Zusatzsäulen abstützen, daß die Treppen vorgefertigte Treppenstufen aufweisen, die in zwischen zu und von den Zwischenpodesten führende Treppenwangen eingesetzt sind und daß an den Treppenwangen Treppengeländer festgelegt sind.To solve this problem it is provided according to the invention that the room cells have a floor slab with a frame made of steel profiles, rising column elements at the corners, an upper ceiling frame and fully assembled outer walls with parapet, windows, insulation and fire protection that the platforms as between the floor slab and the ceiling plate of a room cell arranged intermediate platforms are formed so that the intermediate platforms are held on one side from cross members defined between the ascending column elements of the room cells and on the other side are supported on cross members which are supported on ascending additional columns that the stairs have prefabricated steps that are used in stair strings leading to and from the intermediate platforms and that handrails are fixed to the stair strings.

Diese Zwischenpodeste werden von beabstandeten Querträgern aufgenommen, die einerseits an den eckseitig angeordneten, aufsteigenden Säulenelementen der Raumzellen und andererseits an aufsteigenden Zusatzsäulen abgestützt sind. Raumzellen mit derart bereits vormontierten Treppen in praktisch endgültiger Ausgestaltung zusammen mit Zwischenpodesten und Geländer ermöglichen eine volle Nutzungsmöglichkeit des Treppenhauses in seiner endgültigen Gestalt und zwar schon während der Bauphase, so daß damit Nottreppen und Notgeländer vermieden und gleichzeitig die Sicherheit für die mit dem Bau Beschäftigten erheblich erhöht wird.These intermediate platforms are received by spaced cross members which are supported on the one hand on the ascending column elements of the room cells arranged on the corner side and on the other hand on ascending additional columns. Room cells with such pre-assembled stairs in a practically final design together with intermediate platforms and railings allow full use of the staircase in its final form, even during the construction phase, so that emergency stairs and emergency handrails are avoided and, at the same time, safety for those involved in the construction work considerably is increased.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous refinements of the invention result from the subclaims.

Die oberen Enden der vom Zwischenpodest aufsteigenden Treppenwangen sind zweckmäßigerweise auf Querträgern des Deckenrahmens der jeweiligen Raumzelle festgelegt, so daß jede Raumzelle einen eigenen Treppenbereich von der Fußbodenebene bis zur oberen Ebene der Deckenplatte aufweist.The upper ends of the stair strings rising from the intermediate platform are expediently fixed on cross members of the ceiling frame of the respective room cell, so that each room cell has its own staircase area from the floor level to the upper level of the ceiling tile.

Dabei ist es auch möglich, daß das Zwischenpodest zweiteilig in unterschiedlichen Höhen mit einer zwischengeschalteten Teiltreppe ausgebildet ist.It is also possible that the intermediate platform is formed in two parts at different heights with an intermediate partial staircase.

Diese zweiteiligen Zwischenpodeste können dabei an ihren zum Treppenhaus innenliegenden Ecken über gesonderte, aufsteigende Säulenelemente abgefangen sein.These two-part intermediate platforms can be intercepted at their corners on the inside of the staircase via separate, ascending column elements.

Besonders vorteilhaft ist es, wenn die Unterseiten der Podeste und Treppen gleich fabrikseitig mit Brandschutzplatten verkleidet sind.It is particularly advantageous if the undersides of the platforms and stairs are covered with fire protection panels at the factory.

Die Brandschutzverkleidung der Treppen kann dabei unterseitig der Treppenwangen und die Treppenstufen überdeckend angebracht sein.The fire protection cladding of the stairs can be attached on the underside of the stair stringers and covering the stairs.

Anhand einer schematischen Zeichnung sind Aufbau und Funktionsweise von Ausführungsbeispielen nach der Erfindung näher erläutert. Dabei zeigen:

Fig. 1 zeigt einen Längsschnitt durch den Treppenhausbereich einer unteren Raumzelle A für ein mehrgeschossiges Fertighaus. Diese Raumzelle weist eine Bodenplatte 1 mit quer verlaufenden Stahlträgern 2 und im dargestellten Schnitt nicht sichtbaren längs verlaufenden Stahlträgern sowie aufsteigenden Säulenelementen 9 an den Ecken und eine oben liegende Deckenplatte 3 mit quer- und längs verlaufenden Stahlträgern 4 und 5 auf. Von der darauf gesetzten Raumzelle B sind gestrichelt nur die Träger 6 und 7 der Bodenplatte 8 dargestellt.Fig. 1 shows a longitudinal section through the staircase area of a lower room cell A for a multi-storey prefabricated house. This room cell has a base plate 1 with transverse steel beams 2 and longitudinal steel beams not visible in the section shown, as well as ascending column elements 9 at the corners and an overhead ceiling plate 3 with transverse and longitudinal steel beams 4 and 5. Of the space cell B placed thereon, only the supports 6 and 7 of the base plate 8 are shown in dashed lines.

In die untere Raumzelle sind nunmehr zunächst zwei Zwischenpodeste 10 und 11 eingesetzt, wobei das untere im Schnitt dargestellte Zwischenpodest 10 auf der linken Seite von einem Querträger 12 abgestützt ist, der zwischen den aus Fig. 3 ersichtlichen, aufsteigenden Säulenelementen 9 festgelegt ist. Auf der rechten Seite wird das Zwischenpodest 10 von einem Querträger 13 gehaltert, der von einer aufsteigenden Zusatzsäule 14 und den in den Längswandungen 46 und 47 nach Fig. 3 angeordneten Säulenträgern 45 abgestützt ist.Two intermediate platforms 10 and 11 are now initially inserted into the lower spatial cell, the lower intermediate platform 10, shown in section, being supported on the left side by a cross member 12, which is fixed between the ascending column elements 9 shown in FIG. 3. On the right side, the intermediate platform 10 is held by a cross member 13 which is supported by an ascending additional column 14 and the column supports 45 arranged in the longitudinal walls 46 and 47 according to FIG. 3.

Zwischen der Bodenplatte 1 und dem unteren Zwischenpodest 10 sind nunmehr entsprechend der gezeigten Darstellung Treppenwangen 15 festgelegt, zwischen denen bereits vorgefertigte Treppenstufen 16 eingesetzt sind.Between the base plate 1 and the lower intermediate platform 10 are now in accordance with the illustration shown Stair strings 15 defined, between which prefabricated steps 16 are used.

Entsprechende Treppenwangen 17 mit eingesetzten Treppenstufen 18 sind in gleicher Weise zwischen dem unteren Zwischenpodest 10 und dem oberen Zwischenpodest 11 eingesetzt.Corresponding stair strings 17 with inserted steps 18 are inserted in the same way between the lower intermediate platform 10 and the upper intermediate platform 11.

Vom oberen Treppenpodest 11 führen dann wiederum Treppenwangen 19 mit eingesetzten Treppenstufen 20 zur Dekkenplatte 3. Der sichtbare Bereich des Längsträgers 5 zwischen dem Querträger 4 und einem weiteren Querträger 21 ist dabei als Treppenhausöffnung freigelassen, so daß sich erst rechts anschließend an den Querträger 21 die eigentliche Deckenisolierung und Verkleidung 3 anschließt. Die Treppenwangen 19 sind nunmehr am oberen Ende auf dem Querträger 21 abgestützt und schließen unmittelbar an den nur gestrichelt eingezeichneten Querträger 22 der Bodenplatte 8 der nächsten aufgesetzten Raumzelle B an und bilden damit den Abschluß der Treppe zum ersten Geschoß.From the upper stair landing 11 then again lead cheeks 19 with inserted steps 20 to the ceiling tile 3. The visible area of the longitudinal beam 5 between the cross member 4 and another cross member 21 is left open as a stairwell opening, so that the actual right only afterwards on the cross member 21 Ceiling insulation and cladding 3 connects. The stair stringers 19 are now supported at the upper end on the cross member 21 and directly adjoin the cross member 22 of the base plate 8 of the next attached room cell B, which is shown in dashed lines, and thus form the end of the stairs to the first floor.

Zusätzlich sind aus der dargestellten Figur noch eine Brandschutzverkleidung 23 unterhalb der Treppenwangen 15 bzw. der Stufen 16 sowie weitere Brandschutzplatten 24 unterhalb des Zwischenpodestes 10 zu erkennen. In gleicher Weise ist auch das obere Zwischenpodest 11 sowie die Treppenwangen 19 mit den Stufen 20 auf der Unterseite mit Brandschutzplatten verkleidet.In addition, a fire protection cladding 23 below the stair stringers 15 or steps 16 and further fire protection plates 24 below the intermediate platform 10 can be seen from the figure shown. In the same way, the upper intermediate platform 11 and the stair stringers 19 with the steps 20 on the underside are clad with fire protection plates.

Fig. 2 zeigt einen Schnitt durch ein mehrstöckiges Treppenhaus, wobei die Trennlinien zwischen der unteren Raumzelle A und der Raumzelle B der ersten Etage entsprechend der Schnittlinie I - I verläuft und die zwischen der Raumzelle B und der Raumzelle C der zweiten Etage entlang der Schnittlinie II - II.Fig. 2 shows a section through a multi-storey staircase, the dividing lines between the lower room cell A and the room cell B of the first floor according to the section line I - I and that between the room cell B and the room cell C of the second floor along the section line II - II.

Für die untere Raumzelle sind die gleichen Bezugsziffern wie in Fig. 1 verwendet worden, d.h. die Treppenwangen 15 mit den Stufen 16 führen von der unteren Bodenplatte 1 zum ersten Zwischenpodest 10, von hier die Treppenstufen 18 mit den Wangen 17 zum zweiten Zwischenpodest 11 und von hier die Wangen 19 mit den Stufen 20 zur Bodenplatte 8 der aufgesetzten Raumzelle B der ersten Etage. Diese aufgesetzte Raumzelle B weist in gleicher Weise ein unteres Zwischenpodest 30 und ein oberes Zwischenpodest 31 auf, wobei hier wiederum Treppenwangen 32 mit Stufen 33 von der Bodenplatte 8 der ersten Etage zum Zwischenpodest 30 führen und anschließend vom Zwischenpodest 31 entsprechende Treppenwangen 34 mit Treppenstufen 35 zur Bodenplatte 36 der zweiten Etage.The same reference numbers as in Fig. 1 have been used for the lower space cell, i.e. the stair stringers 15 with the steps 16 lead from the lower base plate 1 to the first intermediate platform 10, from here the stair steps 18 with the stringers 17 to the second intermediate platform 11 and from here the cheeks 19 with the steps 20 to the base plate 8 of the attached room cell B of the first Floor. This attached room cell B has in the same way a lower intermediate platform 30 and an upper intermediate platform 31, here again stairs 32 with steps 33 lead from the base plate 8 of the first floor to the intermediate platform 30 and then from the intermediate platform 31 corresponding stairs 34 with steps 35 to Floor plate 36 of the second floor.

Gleichzeitig sind in diesem Schnittbild die bereits fabrikseitig auf die entsprechenden Treppenwangen 15 und 19 bzw. 32 und 34 aufgesetzten und fertig montierten Geländer 40, 41, 42 und 43 zu erkennen sowie gleichzeitig die sich zwischen den Zwischenpodesten 10 und 30 erstreckenden Verlängerungen 37 der Zusatzsäulen 14 zum Abfangen der Zwischenpodeste.At the same time, the sectional view shows the railings 40, 41, 42 and 43 already installed and factory-fitted on the corresponding stair strings 15 and 19 or 32 and 34, as well as the extensions 37 of the additional columns 14 extending between the intermediate platforms 10 and 30 to intercept the intermediate platforms.

In dem Querschnitt nach Fig. 3 ist eine Aufsicht auf dieses Treppenhaus dargestellt im Verlauf vom Erdgeschoß bis zur ersten Etage mit den beiden voneinander abgesetzten Zwischenpodesten 10 und 11 sowie den Stufenreihen 16, 18 und 20. Außerdem sind in diesem Schnitt noch die aufsteigenden Hauptsäulen 9 an den Ekken jeder Raumzelle zu erkennen, zwischen denen bereits vorgefertigte Wandelemente 45 an der Stirnseite sowie 46 und 47 an den Längsseiten eingesetzt sind.In the cross section according to FIG. 3, a view of this staircase is shown in the course from the ground floor to the first floor with the two intermediate platforms 10 and 11 separated from one another and the rows of steps 16, 18 and 20. In addition, the ascending main pillars 9 are in this section can be recognized by the corners of each room cell, between which prefabricated wall elements 45 are inserted on the front side and 46 and 47 on the long sides.

Durch diese Vormontage praktisch fertiger Treppenhausabschnitte bereits in der Fabrik bei der Herstellung der einzelnen Raumzellen steht an der Baustelle sofort ein begehbares und praktisch fertiges Treppenhaus zur Verfügung, das allen statischen Anforderungen genügt und gleichzeitig der erforderlichen Feuerwiderstandsklasse F90 für den fertig erstellten Bau entspricht. Ein weiterer wesentlicher Vorteil besteht darin, daß bei einem Umbau das gesamte Treppenhaus versetzbar ist, ohne gesondert ausgebaut und später wiedereingebaut werden zu müssen.This pre-assembly of practically finished staircase sections already in the factory during the manufacture of the individual room cells means that a walk-in and practically finished staircase is immediately available at the construction site, which meets all structural requirements and at the same time corresponds to the required fire resistance class F90 for the completed building. Another major advantage is that the entire staircase can be moved during a renovation without having to be separately removed and later reinstalled.
