Abstract

The prefabricated room cell is made from concrete and comprises a base plate (2), ceiling plate (3) and side walls (4). At least the walls (4) are cast as a monolith from concrete and on one side there is a concealed shuttering which has plates (8) of concrete provided with a flat surface reinforcement. Further elements such as webs or grid supports protruding from the concrete plates project into the concrete used to cast the walls. At least one wall is thicker than its opposite wall.

Description

Die Erfindung betrifft eine transportable, vorgefertigte, im Wesentlichen geschosshohe Raumzelle zum Einbau in Gebäude, die im Wesentlichen aus Beton besteht, in dem eine Bewehrung vorhanden ist, wobei die Raumzelle eine Bodenplatte, eine Deckenplatte und Seitenwände aufweist.The invention relates to a transportable, prefabricated, substantially floor-high room cell for installation in buildings, which consists essentially of concrete, in which a reinforcement is present, wherein the space cell has a bottom plate, a ceiling plate and side walls.

Derartige Raumzellen werden beispielsweise als Fertigbäder hergestellt mit einer vollständigen Ausstattung an Sanitärelementen wie Waschbecken, Toiletten, Badewannen, etc. Solche Fertigbäder werden dann häufig in Krankenhäusern, Hotels oder Wohnheimen eingesetzt, da sie den Vorteil haben, dass alle Gewerke, die für eine derartiges Bad notwendig sind (Sanitärinstallation, Fliesenlegung, etc.) zentral fabrikmäßig erfolgen können. Dadurch ist eine erhebliche Bauzeitverkürzung möglich.Such room cells are made, for example, as prefabricated bathrooms with a complete set of sanitary elements such as sinks, toilets, bathtubs, etc. Such prefabricated bathrooms are then often used in hospitals, hotels or dormitories, since they have the advantage that all trades that for such a bath necessary (sanitary installation, tiling, etc.) can be done centrally factory. As a result, a significant reduction in construction time is possible.

Außer Fertigbädern werden aber auch Technikräume als entsprechende Raumzellen vorgefertigt, in denen dann beispielsweise die Heizung vormontiert ist, etc. Des weiteren ist bekannt, in solchen Raumzellen Geschosstreppen einzuplanen bzw. einzubauen.Apart from prefabricated bathrooms but also technical rooms are prefabricated as appropriate room cells, in which then, for example, the heater is pre-assembled, etc. Furthermore, it is known to plan or install Geschosstreppen in such space cells.

Bei den bisher bekannten Raumzellen, wie sie beispielsweise aus der DE-A-44 02 733 bekannt sind, werden mehrere Teilelemente hergestellt. Beispielsweise fertigt man die Bodenplatte mit zwei angrenzenden Wänden sowie die Deckenplatte mit zwei weiteren angrenzenden Wänden jeweils separat und setzt dann die sich dabei ergebenden Winkel (mit jeweils drei Flächen) zu der Gesamtraumzelle zusammen (die dann insgesamt sechs Flächen aufweist).In the previously known space cells, as they are known for example from DE-A-44 02 733, several sub-elements are produced. For example, one manufactures the bottom plate with two adjacent walls and the ceiling plate with two other adjacent walls each separately and then sets the resulting angle (with three surfaces) to the total space cell together (which then has a total of six surfaces).

In der DE-A-33 04 907 bzw. der DE-A-44 46 508 wird dabei beschrieben, dass die Verbindung dieser Winkelelemente vorteilhafterweise über an den Kanten freiliegende Stahlplatten erfolgen kann, die zur Verbindung der Baugruppen miteinander verschweißt werden.In DE-A-33 04 907 and DE-A-44 46 508 it is described that the connection of these angle elements advantageously over exposed at the edges Steel plates can be made, which are welded together to connect the modules.

Dies ist insofern problematisch, als bereits bei der Herstellung der Winkelelemente entsprechende Stahlplatten positionsgenau vorgesehen werden müssen. Weiterhin erfordert das Zusammensetzen der beiden Winkelelemente einen relativ hohen Handling-Aufwand, da zumindest eines der beiden Winkelelemente nach der Herstellung zu drehen und anschließend mit einem Kran zu versetzen ist.This is problematic insofar as corresponding steel plates must already be provided with exact position in the production of the angle elements. Furthermore, the assembly of the two angle elements requires a relatively high handling effort, since at least one of the two angle elements to rotate after manufacture and then to move with a crane.

Beides erfordert eine hohe Präzision und auch einen hohen Personalaufwand, was unter Kostengesichtspunkten ungünstig zu bewerten ist.Both require high precision and also a high personnel costs, which is unfavorable from a cost point of view.

Für Fertiggaragen, die im Wesentlichen geschosshohe Raumzellen bilden, die aber nicht zum Einbau in Gebäude vorgesehen sind, wird in diesem Zusammenhang in der DE-A-198 15 520 vorgeschlagen, die Seitenwandungen als Verbundwandungen auszubilden. Bei dieser wird dann eine Innenschalung und eine dazu beabstandet angeordnete Außenschalung vorgesehen und in den von diesen eingeschlossenen Zwischenraum wird Beton eingefüllt.For prefabricated garages, which essentially form floor-to-ceiling room cells, but which are not intended for installation in buildings, it is proposed in this context in DE-A-198 15 520 that the side walls be formed as composite walls. In this then an inner formwork and an outer form spaced therefrom is provided and into the space enclosed by these concrete is filled.

Hierdurch wird zwar eine einfachere Herstellbarkeit entsprechender Raumzellen erreicht. Es ergibt sich aber als erheblicher Nachteil, dass sich bei diesem Verfahren relativ dicke Wände ergeben. Abgesehen davon, dass bei der DE-A-198 15 520 die dort vorgeschlagene verlorene Schalung mit ausgeprägten Wölbungen versehen ist, die im Innenraumbereich eines Hauses unter ästhetischen Gesichtspunkten nicht tolerierbar sind, wird in dieser Druckschrift auch noch vorgeschlagen, die Schalungsteile parallel zu ihrer Erstreckung fluiddurchlässig auszubilden, so dass hier gegebenenfalls ein flüssiger Wärmeträger hindurchzuleiten ist, der eine schnellere Aushärtung des ausgegossenen Betons bewirken soll.Although this achieves a simpler producibility of corresponding space cells. However, it results as a considerable disadvantage that result in this method relatively thick walls. Apart from the fact that in DE-A-198 15 520 there proposed permanent formwork is provided with pronounced curvatures that are intolerable in the interior of a house from an aesthetic point of view, this document also proposes that the formwork parts parallel to their extension form fluid permeable, so that here, if necessary, a liquid heat transfer medium is passed, which is intended to effect a faster curing of the poured concrete.

Damit wird ein wesentlicher Nachteil einer derartigen Raumzelle, nämlich ihre recht dicken Wände, durch die spezielle Ausgestaltung der verlorenen Schalung in ihrer fluiddurchlässigen Form noch einmal erhöht.Thus, a major disadvantage of such a room cell, namely its fairly thick walls, increased by the special design of the lost formwork in its fluid-permeable form again.

Jetzt ist es aber ein erhebliches Problem, dass bei in Gebäuden einzusetzenden Raumzellen eine möglichst höhe Raumeffizienz erreicht werden soll, um je umbauten Quadratmeter Raum eine möglichst hohe Nutzfläche zur Verfügung zu stellen.Now, however, it is a significant problem that for space cells to be used in buildings, the highest possible space efficiency is to be achieved in order to provide as much usable space as possible per square meter of space.

Daneben ist durch die DE-A-31 25 551 eine Raumzelle aus Beton, insbesondere eine Fertiggarage, bekannt geworden, bei der die Seitenwände nach unten ragende Bewehrungsstäbe aufweisen, die beim anschließenden Anbetonieren der Bodenplatte die gewünschte Verbindung zwischen beiden Teilen herstellen.In addition, by DE-A-31 25 551 a cell of concrete, in particular a prefabricated garage, become known, in which the side walls have downwardly projecting reinforcing bars, which produce the desired connection between the two parts in the subsequent Anbetonieren the bottom plate.

Der Oberbegriff des Patentanspruches 1 geht von der US 4,107,886 aus. Dort werden vorgefertigte Raumzellen beschrieben, die aus einer Bodenplatte, einer Deckenplatte und zwei Seitenwänden bestehen. Die Bodenplatte, Deckenplatte und Seitenwände bestehen jeweils aus betonähnlichen Platten mit einer nach außen vorstehenden Bewehrung. Die Bewehrungen sind an den Eckpunkten durch eingeschweißte Metallplatten miteinander verbunden. Diese Raumzellen werden dann nebeneinander und übereinander gestapelt, wobei die Seitenwände benachbarter Raumzellen einen Zwischenraum bilden, in dem die Bewehrungen verlaufen. Dieser Zwischenraum wird dann mit Beton ausgefüllt, so dass benachbarte Raumzellen miteinander verbunden werden.The preamble of claim 1 is based on the US 4,107,886. There prefabricated space cells are described, which consist of a bottom plate, a ceiling plate and two side walls. The base plate, ceiling plate and side walls each consist of concrete-like plates with an outwardly projecting reinforcement. The reinforcements are connected together at the corners by welded metal plates. These space cells are then stacked side by side and one above the other, with the side walls of adjacent space cells forming a space in which the reinforcements pass. This space is then filled with concrete, so that adjacent space cells are interconnected.

Aufgabe der vorliegenden Erfindung ist es daher, eine Raumzelle wie oben angegeben derart weiterzubilden, dass eine hohe Räumeffizienz zu erreichen ist. Gleichzeitig soll eine derartige Raumzelle aber auch einfach zu fertigen sein, wobei die Fertigung mit hoher Effektivität erfolgen soll.The object of the present invention is therefore to refine a room cell as indicated above in such a way that a high clearing efficiency can be achieved. At the same time such a space cell but also be easy to manufacture, the production should be done with high efficiency.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst.This object is achieved by the features of claim 1.

Ein wesentlicher Vorteil dieser Erfindung liegt jetzt darin, dass eine erfindungsgemäße Raumzelle sehr dünne Wände haben kann, da die verlorene Schalung aufgrund ihres Bestehens aus Beton und ihrer flächigen Bewehrung bei der Auslegung für die statischen Belastungen der fertigen Raumzelle mit berücksichtigt werden kann. Über die aus der Platte vorstehenden Elemente wird dabei mit dem einzugießenden Beton eine innige Verbindung erreicht. Es lassen sich somit ohne größere Probleme tragende Wände von lediglich 9 cm Dicke herstellen, so dass bei einer fest vorgegebenen Grundfläche nur minimalste Flächen für die Standflächen von Wänden vorzusehen sind. Die letztlich nutzbare Grundfläche wird somit maximiert.An essential advantage of this invention is now that a room cell according to the invention can have very thin walls, since the lost formwork due to their existence in concrete and their areal reinforcement in the design for the static loads of the finished room cell can be taken into account. An intimate connection is achieved with the concrete to be poured in via the elements protruding from the plate. It can thus be produced without major problems supporting walls of only 9 cm thickness, so that are provided with a fixed base area only minimal surfaces for the footprint of walls. The ultimately usable area is thus maximized.

Dadurch, dass aus der Platte der verlorenen Schalung Distanzhalter herausragen, die die Stege überragen, kann mit einer gegen die verlorene Schalung gesetzten, herkömmlichen Schalung ein exakter Zwischenraum zum Befüllen mit dem zu gießenden Beton erreicht werden.The fact that protrude from the plate of the lost formwork spacers that extend beyond the webs, can be achieved with a set against the lost formwork, conventional formwork, an exact space for filling with the concrete to be poured.

Bei einer bevorzugten Ausführungsform der Erfindung ist dabei mindestens eine Seitenwand dicker als die ihr gegenüberliegende Wand. Damit ist zu erreichen, dass die im Verbund in ein Gebäude eingesetzte Raumzelle gleichzeitig genutzt werden kann, um Aussteifungsfunktionen zu übernehmen. Über die dickere Wand können dabei Scherkräfte besser abgebaut werden, die durch ein Aussteifungselement zu kompensieren sind.In a preferred embodiment of the invention, at least one side wall is thicker than the wall opposite it. It can thus be achieved that the room cell used in a building in a building can be used at the same time to take over stiffening functions. On the thicker wall shear forces can be better reduced, which are compensated by a stiffening element.

Davon abgesehen bleibt die bisherige Funktion der hier beschriebenen monolithischen Raumzelle bestehen, in dem Gebäude, in dem sie integriert ist, auch unter statischem Aspekt eine tragende Funktion zu übernehmen.Apart from that, the previous function of the monolithic space cell described here remains to take on a supporting function in the building in which it is integrated, even under a static aspect.

Bei einer bevorzugten Ausführungsform sind die an der verlorenen Schalung vor-gesehenen Elemente in Form von als Gitterträger ausgebildeten Stegen vorgesehen. Derartige, insbesondere aus Baustahl bestehenden Elemente bzw. Stege sind preiswert herstellbar und nehmen dabei hohe Belastungen auf, wobei dann gleichzeitig eine sehr gute Verbindung der als Gitterträger ausgebildeten Elemente mit dem einzugießenden Beton erreicht wird.In a preferred embodiment, the pre-seen on the lost formwork elements are provided in the form of webs designed as a lattice girder. Such, in particular made of structural steel elements or webs are inexpensive to produce and take on high loads, in which case at the same time a very good connection of the trained as a lattice girder elements is achieved with the concrete to be poured.

Es wird dabei als vorteilhaft angesehen, die Stege im Wesentlichen lotrecht entlang der Wände verlaufen zu lassen.It is considered advantageous to let the webs run substantially vertically along the walls.

Durch den einzugießenden Beton, der alle Seitenwände monolithisch miteinander verbindet, wird eine besonders starre Struktur der transportablen Raumzelle erreicht. Diese kann noch dadurch verbessert werden, dass die Platten der verlorenen Schalung an den einander zugewandten Stosskanten in den Eckbereichen der Raumzelle mit entsprechenden Gehrungsfasen versehen sind, was eine besonders passgenaue Verbindung ermöglicht.The concrete to be infiltrated, which monolithically connects all the side walls, creates a particularly rigid structure of the transportable room cell. This can be further improved by the fact that the plates of the lost formwork at the mutually facing butt edges in the corner areas the space cell are provided with corresponding Miter bevels, which allows a particularly accurate connection.

Weiterhin sind die Bodenplatte und die Deckenplatte im wesentlich kongruente vorgefertigte Teile, die an ihren Rändern entsprechende umlaufende Aufnahmen aufweisen, in die die Platten der verlorenen Schalung eingreifen, mit denen die Seitenwände der Raumzelle gegossen werden. Durch diese Aufnahmen wird eine Stabilisierung der verlorenen Schalung erreicht, während diese noch nicht mit Beton eingegossen ist.Furthermore, the bottom plate and the top plate are substantially congruent prefabricated parts having at their edges corresponding circumferential receptacles in which engage the plates of the lost formwork, with which the side walls of the space cell are poured. Through these shots stabilization of the lost formwork is achieved while this is not poured with concrete.

Insbesondere sollen diese Aufnahmen dabei als Stufen ausgebildet sein, die die Platten sowohl in Richtung zum Inneren der Raumzelle stützen als auch parallel zu der Fläche der die verlorene Schalung im Wesentlichen bildenden Platten. Durch die Abstützung parallel zur Plattenfläche wird die Stabilisierung der noch nicht vergossenen verlorenen Schalung während der Vorbereitungsphase unterstützt, während durch die Abstützung in Richtung zum Zelleninneren eine gute Passgenauigkeit der fertigen Raumzelle zu erreichen ist. Die Platten der verlorenen Schalung an den Seitenwänden werden nämlich durch den einzugießenden Beton in Richtung des Zelleninneren gedrückt.In particular, these recordings should be designed as steps that support the plates both toward the interior of the space cell and parallel to the surface of the lost formwork substantially forming plates. By supporting parallel to the plate surface stabilization of the not yet cast lost formwork during the preparation phase is supported, while by supporting towards the cell interior a good fit accuracy of the finished room cell can be achieved. The panels of the lost formwork on the side walls are in fact pressed by the concrete to be poured in the direction of the cell interior.

An der Bodenplatte und der Deckenplatte können im übrigen noch seitlich überstehende Bewehrungen vorgesehen sein, die in den zu gießenden Beton der Seitenwände hineinragen. Hiermit wird eine starre Verbindung von Seitenwänden und Decke erreicht. Dabei soll der zu gießende Beton die Bodenplatte und die Deckenplatte an deren Rand einbinden, um hier ein besonders innigen Verbund zur Stabilisierung der fertigen Raumzelle zu erreichen.On the bottom plate and the ceiling plate can also be provided laterally projecting reinforcements, which protrude into the concrete to be poured, the side walls. Hereby a rigid connection of side walls and ceiling is achieved. Here, the concrete to be cast to embed the bottom plate and the ceiling plate at the edge, in order to achieve a particularly intimate bond to stabilize the finished room cell.

Ein weiterer Vorschlag, um die Raumzelle zu stabilisieren, ist, dass an wenigstens zwei an einer Ecke aneinanderstoßenden Platten eine als Faltwerk ausgebildete, aus Beton monolithisch gegossene, gewendelte Treppe angesetzt ist.Another proposal to stabilize the space cell, is that at least two adjacent to a corner plates a folded as a concrete monolithically cast, spiral staircase is attached.

Es hat sich dabei herausgestellt, dass über eine derartige Treppe die Verwindungssteifigkeit der Raumzelle verbessert werden kann. Die Raumzelle kann somit insbesondere die oben bereits angesprochene Aussteifungsfunktion innerhalb eines Gebäudes besser übernehmen.It has been found that the torsional stiffness of the room cell can be improved by such a staircase. The room cell can thus better take over the stiffening function already mentioned above within a building.

Mit einem Faltwerk lässt sich außerdem eine sehr raumökonomische Treppe realisieren, die aufgrund ihrer Fixierung an den Wänden bzw. an der verlorenen Schalung auch ohne eine Mittelstütze ausgeführt werden kann und somit auch optisch sehr leicht wirkt.With a folding mechanism, it is also possible to realize a very space-saving staircase which, due to its fixation on the walls or on the lost formwork, can also be executed without a central support and thus also looks very light visually.

Dabei sind die aus Beton bestehenden Platten der Schalung ein sehr gutes Widerlager, die den Treppenstufen die notwendige Abstützung bieten.The concrete slabs of the formwork are a very good abutment that provides the stairs with the necessary support.

Um eine ausreichende Schallisolierung der Treppe gegenüber der Wandung sicherzustellen, kann das die Treppe bildende Faltwerk gegebenenfalls auch lediglich an wenigen Auflagepunkten mit der Wandung verbunden sein, wobei hier übliche Schallentkopplungsvorrichtungen verwandt werden können. Die aussteifende Funktion des als Treppe fungierenden Faltwerks bleibt dabei jedoch erhalten.In order to ensure sufficient sound insulation of the stairs opposite the wall, the fold forming the staircase may possibly also be connected to the wall only at a few support points, in which case conventional sound decoupling devices can be used. However, the stiffening function of acting as a staircase folding remains intact.

In Figur 1 erkennt man den Schnitt durch eine vorgefertigte Raumzelle, die als Ganzes mit 1 bezeichnet wird. Diese Raumzelle weist eine Bodenplatte 2 auf sowie dieser gegenüberliegend eine im Wesentlichen kongruente Deckenplatte 3. Zwischen Bodenplatte 2 und Deckenplatte 3 erstrecken sich Seitenwände 4. Diese Seitenwände 4 weisen zum Raumzelleninneren 5 gerichtet eine verlorene Schalung 6 auf, die mit Beton 7 umgossen ist.FIG. 1 shows the section through a prefabricated space cell, which is denoted as a whole by 1. This room cell has a bottom plate 2 and this opposite a substantially congruent ceiling plate 3. Between bottom plate 2 and top plate 3 side walls extend 4. These side walls 4 have directed to the interior space cells 5 a permanent formwork 6, which is encapsulated with concrete 7.

In der Figur 4 erkennt man den entsprechenden Aufbau der Seitenwände 4 im Schnitt genauer. Man erkennt, dass die verlorene Schalung eine Platte 8 aufweist, die aus Beton besteht. In dieser ist eine flächige Bewehrung 9 verlegt in Form von Stahlmatten oder ähnlichem. Die Platte 8 hat dabei eine übliche Dicke von ca. 3,5 cm, die es ermöglicht, dass die innerhalb der Platten verlegte im Wesentlichen flächige Bewehrung 9 mit einer üblichen Stärke von 5 mm die vorgeschriebene Überdeckung aufweist.In the figure 4 can be seen the corresponding structure of the side walls 4 in section more precisely. It can be seen that the lost formwork has a plate 8, which consists of concrete. In this is a two-dimensional reinforcement 9 laid in the form of steel mats or the like. The plate 8 has a usual thickness of about 3.5 cm, which makes it possible that the laid inside the plates substantially flat reinforcement 9 with a standard thickness of 5 mm has the prescribed coverage.

Aus dieser Platte 8 ragen Elemente 10 hervor. Diese Elemente 10 sind im hier dargestellten Ausführungsbeispiel als Gitterträger ausgebildet, die sich mit ihren Diagonalen und ihren Obergurten in den zu gießenden Beton 7 erstrecken, mit dem die Platte 8 somit eine innige Verbindung erhält. Dabei sind die Untergurte der beschriebenen und dargestellten Gitterträger in die Bewehrung 9 integriert, die innerhalb der als verlorenen Schalung dienenden Platte 8 verläuft.From this plate 8 protrude elements 10. These elements 10 are formed in the embodiment shown here as a lattice girder, with their Diagonals and their upper straps extend into the concrete to be poured 7, with which the plate 8 thus receives an intimate connection. In this case, the lower chords of the lattice girders described and illustrated are integrated in the reinforcement 9, which extends within the plate 8 serving as lost formwork.

Dabei sei bemerkt, dass die Platte 8 im Wesentlichen aus einem vergleichbaren Beton wie der Beton 7 besteht, so dass die Platte 8 und der hinter diese zu gießende Beton 7 im Wesentlichen gleiche Ausdehnungsquotienten, etc. haben und sich somit bei einer Belastung nicht voneinander trennen.It should be noted that the plate 8 substantially consists of a concrete comparable to the concrete 7, so that the plate 8 and the concrete to be cast behind 7 have substantially equal coefficients of expansion, etc. and thus do not separate under load ,

In der Figur 2 ist weiterhin zu erkennen, dass aus der Platte 8 Abstandhalter 11 hervorragen. Gegen diese wird bei Herstellung der Wand 4 eine (nicht dargestellte) Schalung gedrückt. In den sich dabei zwischen der Platte 8 und dieser Schalung ergebenden Spalt wird dann der Beton 7 eingefüllt. Nach Entfernen der Schalung erhält man dann die schalungsglatte Oberfläche 12 der fertigen Wand 4.In FIG. 2 it can also be seen that spacers 11 project from the plate 8. Against this, a (not shown) formwork is pressed in the manufacture of the wall 4. In the case between the plate 8 and this formwork resulting gap then the concrete 7 is filled. After removal of the formwork, the smooth-surfaced surface 12 of the finished wall 4 is then obtained.

Über die Abstandhalter 11 lässt sich somit bestimmen, wie dick die zu gießende Wand wird. Während für rein statische Lastaufnahmen und für den Brandschutz dabei Wandstärken von ca. 9 cm ausreichen, werden Wände, die bei entsprechender Integration der Raumzelle in ein Gebäude für Aussteifungszwecke benutzt werden, auch größere Dicken aufweisen wie 11 cm, 13 cm oder gar 16 cm. Die hier vorgesehene Dicke ist aber so gering wie möglich zu wählen, damit die für Wandquerschnitte benötigte Grundfläche nicht unnötig groß wird.The spacers 11 can thus be used to determine how thick the wall to be cast becomes. While wall thicknesses of approx. 9 cm are sufficient for purely static load absorption and for fire protection, walls that are used with appropriate integration of the room cell into a building for reinforcement purposes will also have larger thicknesses such as 11 cm, 13 cm or even 16 cm. However, the thickness provided here is to be chosen as small as possible so that the base area required for wall cross-sections does not become unnecessarily large.

Es sei noch erwähnt, dass vor dem Vergießen mit dem Beton 7 an der Platte 8 Leerrohre 13 oder ähnliche Installationsmaterialien befestigt werden können, die somit sicher in die Wand 4 zu integrieren sind.It should be noted that before casting with the concrete 7 on the plate 8 conduits 13 or similar installation materials can be attached, which are thus safe to integrate into the wall 4.

In der Figur 3 erkennt man noch den üblichen Verlauf, der für die Stege 10 vorgeschlagen wird. Man erkennt, dass die Stege im Wesentlichen lotrecht entlang der Wand 4 verlaufen, wobei sie im Bereich von Türausschnitten 14 oder vergleichbaren Fensterausschnitten ausgespart werden. An ihren seitlichen Kanten 15 stoßen die Seitenwände 4 dabei aneinander, wie in der Figur 4 zu erkennen: Die einzelnen Platten 8 sind in diesem Bereich der seitlichen Kanten 15 mit einer Gehrung 16 von ca. 45° versehen, so dass bei Aneinanderstoßen der Seitenkanten 15 von den beiden Platten 8 ein rechter Winkel gebildet wird. Man erhält somit eine passgenaue Ecke 17.In the figure 3 can still recognize the usual course, which is proposed for the webs 10. It can be seen that the webs extend essentially perpendicularly along the wall 4, wherein they are recessed in the region of door cutouts 14 or comparable window cutouts. At their lateral edges 15, the side walls 4 abut one another, as can be seen in FIG. 4: The individual plates 8 are mitred in this region of the lateral edges 15 16 provided by about 45 °, so that when abutting the side edges 15 of the two plates 8, a right angle is formed. One thus obtains a precisely fitting corner 17.

In dem Bereich der Seitenkanten 15 hinter der Gehrung 16 können somit vor dem Ausgießen mit Beton 7, mit dem die aneinander anstoßenden Seitenwände monolithisch hergestellt werden, die oben angesprochenen Leerrohre oder ähnliches um die Ecke 17 herumgeführt werden, so dass in diesem Bereich nicht mehr wie bisher Anschlüsse vorgesehen werden müssen, die wegen ihrer Montage und später wegen ihrer Dichtigkeit kritisch und daher unerwünscht sind.In the area of the side edges 15 behind the miter 16 thus before pouring concrete 7, with which the adjoining side walls are made monolithic, the above-mentioned conduits or the like around the corner 17 are guided around, so that no longer in this area previously connections must be provided, which are critical because of their assembly and later because of their tightness and therefore undesirable.

Die Gehrung 16 hat weiterhin den Vorteil, dass der Beton 7 die beiden Platten 8 zusammendrückt, damit sie sich gegeneinander abstützen.The miter 16 also has the advantage that the concrete 7 compresses the two plates 8, so that they are supported against each other.

Eine weitere Abstützung der Platten 8 erkennt man in der Figur 5: Man sieht hier einen Schnitt durch die Kanten, an denen bei der Raumzelle der Boden und die Decke mit den Wänden verbunden ist. Man erkennt, dass die Platte 8 auf der Bodenplatte 2 aufsitzt, wobei hierfür die Bodenplatte 2 eine umlaufende Aufnahme in Form einer Stufe 18 ausgebildet hat. Diese Stufe stützt mit ihrem senkrechten Bereich die Platte 8 gegen den Druck des Betons 7 ab, wobei eine saubere Bodenkante 19 erreicht wird. Aus Stabilitätsgründen sitzt dabei die Platte 8 auch auf dem im Wesentlichen horizontalen Bereich der Stufe 18 auf, um bis zum erfolgenden Abgießen mit dem Beton 7 in der Position fixiert zu sein.A further support of the plates 8 can be seen in Figure 5: Here is a section through the edges, where in the room cell, the floor and the ceiling is connected to the walls. It can be seen that the plate 8 rests on the bottom plate 2, for which purpose the bottom plate 2 has formed a peripheral receptacle in the form of a step 18. This step supports with its vertical area the plate 8 against the pressure of the concrete 7, with a clean bottom edge 19 is achieved. For reasons of stability, the plate 8 also sits on the substantially horizontal region of the step 18 in order to be fixed in the position until successful casting off with the concrete 7.

Um später die innige Verbindung der Seitenwand 4 mit der Bodenplatte 2 sicherstellen zu können, verläuft aus der Bodenplatte 2 eine seitlich überstehende Bewehrung 20 in den Bereich des Betons 7, wodurch eine ausreichende Verbindung bewirkt wird. In gleicher Weise verläuft aus der Deckenplatte 3 eine Bewehrung 21 in die Seitenwand 4 hinein und bildet dort nach Abbinden des Betons 7 die notwendige starre Verbindung.In order to ensure later the intimate connection of the side wall 4 with the bottom plate 2, extends from the bottom plate 2, a laterally projecting reinforcement 20 in the region of the concrete 7, whereby a sufficient connection is effected. In the same way extends from the ceiling plate 3, a reinforcement 21 in the side wall 4 into it and forms after setting of the concrete 7, the necessary rigid connection.

Man erkennt in der Figur 5 auch, dass der Beton 7 die Bodenplatte 2 bzw. die Deckenplatte 3 an deren Rändern 22 bzw. 23 einbindet, wobei im hier dargestellten Beispiel die Bodenplatte 2 vom Beton 7 bis in einen Hinterschnitt 24 untergriffen wird. Seitlich neben diesem Hinterschnitt 24 ist dabei unter der Bodenplatte 2 eine Isolierung 25 vorgesehen, sei es zur Wärme- oder aber zur Trittschalldämmung. In dem unter der Bodenplatte 2 mit Isolierung 25 gefüllten Raum können auch noch Installationen vorgesehen werden, wobei hier beispielhaft ein Leer- oder Abwasserrohr 26 dargestellt ist.It can be seen in Figure 5 also that the concrete 7, the bottom plate 2 and the ceiling plate 3 at the edges 22 and 23 einbindet, wherein in the example shown here, the bottom plate 2 from the concrete 7 into an undercut 24 under attack becomes. On the side next to this undercut 24, an insulation 25 is provided below the bottom plate 2, be it for thermal or impact sound insulation. Installations can also be provided in the space filled with insulation 25 under the floor slab 2, an empty or sewage pipe 26 being shown here by way of example.

Es sei hier noch erwähnt, dass die verlorene Schalung, die aus den Platten 8 mit der Flächenbewehrung und der aus diesen hervorstehenden Stegen 10 besteht, nach bekannten Herstellverfahren für die sogenannten "Filigrandecken" herzustellen sind.It should be mentioned here that the lost formwork, which consists of the plates 8 with the surface reinforcement and the webs 10 protruding therefrom, are to be produced according to known production methods for the so-called "filigree corners".

Besonders vorteilhaft ist dabei, dass die hier verwendete verlorene Schalung später mit in den tragenden Querschnitt der mit ihr gebildeten Seitenwände integriert ist, wodurch diese Seitenwände 4 sehr schmal ausgebildet werden können und damit nur geringe Querschnitte aufweisen. Somit ist eine insgesamt hohe Raumausnutzung möglich.It is particularly advantageous that the lost formwork used here is later integrated with the supporting cross section of the sidewalls formed with it, whereby these side walls 4 can be made very narrow and thus have only small cross sections. Thus, a total of high space utilization is possible.

In der Figur 6 ist das aufgebrochene Ende einer Raumzelle ohne Boden und Decke dargestellt, in der eine als Faltwerk ausgebildete gewendelte Treppe 27 eingesetzt ist. Diese gewendelte Treppe 27 ist dabei an zwei aneinander stoßenden Platten 28 und 29 angesetzt, wodurch hier eine versteifende Wirkung erreicht wird. Die gewendelte Treppe 27, die in der Figur 7 noch einmal als Einzelteil dargestellt ist, ist als Faltwerk einstückig aus Beton gegossen. Dabei sind lediglich in den Stellstufen 30 im Wesentlichen U-förmig verlaufende Bewehrungen vorgesehen, die der gewendelten Treppe ihre Stabilität geben, während in den Trittstufen 31 keine aufwendige Bewehrung vorgesehen sein muss. Die in den Stellstufen verlaufende Bewehrung ist an die außenliegende Stosskante 32 der monolithischen Treppe geführt.In the figure 6, the broken end of a room cell is shown without floor and ceiling, in which a spiral formed as a folded staircase 27 is used. This spiral staircase 27 is attached to two abutting plates 28 and 29, whereby a stiffening effect is achieved here. The spiral staircase 27, which is shown again in the figure 7 as a single part, is cast as a single piece of concrete. In this case, only in the setting stages 30 are provided substantially U-shaped reinforcements that give the spiral staircase their stability, while in the treads 31 no elaborate reinforcement must be provided. The reinforcement running in the setting stages is guided to the outer abutting edge 32 of the monolithic staircase.

An dieser Stosskante kann entweder ein dem Verlauf der Stosskante folgendes Flacheisen 33 angebracht sein, an dem die U-förmige Bewehrung dann angreift. Dieses Flacheisen 33 ist dann wiederum über in der Figur 7 nicht dargestellte Dorne in schalldämmender Weise an den Wänden einer Raumzelle, wie sie in der Figur 6 mit 28 und 29 bezeichnet sind, fixiert. Dabei werden über diese Dorne auch Kräfte geleitet, so dass mit der gewendelten Treppe 27 ein Versteifung und Stabilisierung der Raumzelle erreicht werden kann.At this bumping edge, either a flat bar 33 following the course of the bumper edge can be attached, on which the U-shaped reinforcement then engages. This flat iron 33 is then in turn via not shown in the figure 7 mandrels in a sound-insulating manner on the walls of a room cell, as they are designated in the figure 6 with 28 and 29 fixed. There are also forces on these spines directed, so that with the helical staircase 27, a stiffening and stabilization of the room cell can be achieved.

Es ist aber auch möglich, die U-förmigen Bewehrungen in den Stellstufen 30 direkt an den Platten zu befestigen, die für die Seitenwände 28 und 29 die verlorene Schalung darstellt. Auch dies ist eine Möglichkeit, eine Stabilisierung der Raumzelle zu erhalten..But it is also possible to attach the U-shaped reinforcements in the control stages 30 directly to the plates, which represents the lost formwork for the side walls 28 and 29. Again, this is one way to stabilize the space cell.

Wesentlich ist dabei, dass die als Faltwerk ausgebildete Treppe insbesondere sehr einfach zu armieren ist. Die bisher notwendigen, sehr kompliziert und insbesondere kaum automatisierbar herzustellenden Bewehrungskörbe entfallen.It is essential that the trained as a folded staircase is in particular very easy to arm. The previously necessary, very complicated and in particular hardly automated to produce reinforcement cages omitted.

Auch ist eine derartige als Faltwerk hergestellte Treppe ca. 75 % leichter als die bisherigen monolithischen Treppen, so dass sich eine derartige monolithische Faltwerktreppe insbesondere für nach ihrer Herstellung zu transportierende Fertigelemente eignet unter Berücksichtigung der aus der Transportlogistik resultierenden Gewichtsbeschränkungen.Also, such a staircase made as a folded piece is about 75% lighter than the previous monolithic stairs, so that such a monolithic folding staircase is particularly suitable for ready-made elements to be transported, taking into account the resulting from transport logistics weight restrictions.
