Description

Die Erfindung betrifft eine transportable Beton-Raumzelle nach dem Oberbegriff des Patentanspruches 1.The invention relates to a transportable concrete room cell according to the preamble of claim 1.

Aus der DE-PS-2 110 089 ist eine transportable Beton-Raumzelle mit einem Flachdach bekannt, die im Bereich zwischen dem Flachdach und den Außenwänden der Raumzelle Lüftungsschlitze zur Entlüftung der Raumzelle aufweist. Die Anordnung von Lüftungsschlitzen im Bereich zwischen dem Flachdach und den Außenwänden der Raumzelle hat sich sehr bewährt, da die im Normalbetrieb der Raumzelle erwärmte Abluft aufgrund der thermischen Konvektion in der Raumzelle aufsteigt, unter dem Dach gesammelt und dann vorteilhafterweise von dort nach außen abgeleitet wird. Dies gilt auch und in besonderem Maße für die heißen Gase, die bei einer Explosion im Inneren der Raumzelle entstehen und möglichst schnell und gefahrlos abgeleitet werden sollen.From DE-PS-2 110 089 a transportable concrete room cell with a flat roof is known, which has ventilation slots in the area between the flat roof and the outer walls of the room cell for venting the room cell. The arrangement of ventilation slots in the area between the flat roof and the outer walls of the room cell has proven very successful, since the exhaust air heated during normal operation of the room cell rises in the room cell due to thermal convection, is collected under the roof and is then advantageously discharged from there to the outside. This also and particularly applies to the hot gases that arise in the event of an explosion inside the room cell and that should be discharged as quickly and safely as possible.

Bei der vorbekannten Raumzelle entströmt die Abluft aus dem Innenraum nach außen durch die nach oben gerichteten Lüftungsschlitze. Dies ist dann wichtig, wenn Vorsorge dafür getroffen werden muß, daß der Raumzelle auch heiße Abgase entströmen können - beispielsweise im Falle einer Explosion im Innenraum der Raumzelle - die gefahrlos für Passanten in der Nähe der Raumzelle abgeleitet werden sollen. Soll die Raumzelle jedoch an einem Ort aufgestellt werden, an welchem größere Mengen von Staub, Kohlenstaub, Zementstaub oder Flugschnee anfallen, dann sind die nach oben offenen Lüftungsschlitze nachteilig, weil die durch ein Lochblech stochersicher abgedeckten Lüftungsöffnungen durch den Staub oder Schnee schnell zugesetzt werden können, so daß die Entlüftung der Raumzelle erheblich gestört oder vollständig unterbunden wird. Auch andere Verwendungen einer derartigen Raumzelle, bei denen das Auftreten von Explosionen im Innenraum nicht zu befürchten ist, mögen es wünschenswert erscheinen lassen, die Abluft durch die Abdeckung der Lüftungsschlitze nach unten, d. h. zum Boden gerichtet ausströmen zu lassen. Die Beantwortung der Frage, ob die Austrittsöffnungen der Abdeckung nach oben oder unten gerichtet sein sollen, hängt also vom jeweiligen Verwendungszweck der Raumzelle ab.In the previously known room cell, the exhaust air flows out of the interior to the outside through the ventilation slots directed upwards. This is important if precautions must be taken to ensure that hot exhaust gases can also escape from the room cell - for example in the event of an explosion in the interior of the room cell - which should be safely discharged for passers-by in the vicinity of the room cell. However, if the room cell is to be set up in a location where large amounts of dust, coal dust, cement dust or flying snow are generated, then the ventilation slots open at the top are disadvantageous because the ventilation openings covered by a perforated plate can be quickly clogged by the dust or snow , so that the ventilation of the room cell is significantly disturbed or completely prevented. Other uses of such a room cell, in which the occurrence of explosions in the interior are not to be feared, may make it appear desirable to vent the exhaust air downward through the cover of the ventilation slots, i. H. to flow towards the floor. The answer to the question of whether the outlet openings of the cover should be directed upwards or downwards depends on the particular use of the room cell.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die bekannten Beton-Raumzellen dieser Art so zu verbessern, daß ihre Fertigung unabhängig von der Frage, ob die Abluft nach oben oder unten gerichtet in die Außenumgebung der Raumzelle abgeleitet werden soll, durchgeführt werden kann. Angestrebt wird eine wirtschaftliche Lösung für die Fertigung derartiger Raumzellen, bei der die Richtung der Ableitung der Abluft aus der Raumzelle ggf. erst am Aufstellort festgelegt werden muß. Darüberhinaus soll die äußere Abdeckung der Lüftungsschlitze so gestaltet sein, daß sie problemlos an der Außenseite der Raumzelle befestigbar ist und sich gut in das architektonische Bild der Raumzelle einfügt.The present invention has for its object to improve the known concrete room cells of this type so that their manufacture can be carried out regardless of whether the exhaust air should be directed upwards or downwards into the outside environment of the room cell. The aim is an economical solution for the production of such room cells, in which the direction of the discharge of the exhaust air from the room cell may need to be determined at the installation site. In addition, the outer cover of the ventilation slots should be designed so that it can be easily attached to the outside of the room cell and fits well into the architectural picture of the room cell.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Die beiden Profilbleche sind leicht an der Außenseite der Raumzelle befestigbar. Dabei braucht erst bei der Befestigung entschieden zu werden, ob die Abluft nach oben oder unten abgeleitet werden soll. Bei einer vorteilhaften Ausführungsform besteht das erste Profilblech aus ungelochtem Material und bildet zusammen mit dem Sims des Flachdaches das Gesamtsims der Raumzelle. Fertigungstoleranzen bei den im Bereich zwischen dem Flachdach und den Außenwänden der Raumzelle angeordneten Lüftungsschlitzen können in einfacher Weise durch die kanalförmigen Abdeckungen ausgegelichen werden, so daß sich eine saubere Gestaltung dieses Bereiches der Raumzelle ergibt. Durch unterschiedliche Ausgestaltungen der Abdeckung können interessante reliefartige Strukturierungen des Simses der Raumzelle erreicht werden.This object is achieved by the characterizing features of claim 1. The two profile sheets can be easily attached to the outside of the room cell. It is only necessary to decide at the time of attachment whether the exhaust air should be discharged upwards or downwards. In an advantageous embodiment, the first profiled sheet consists of non-perforated material and, together with the ledge of the flat roof, forms the overall ledge of the room cell. Manufacturing tolerances in the ventilation slots arranged in the area between the flat roof and the outer walls of the room cell can be easily compensated for by the channel-shaped covers, so that a clean design of this area of the room cell results. Interesting relief-like structures of the ledge of the room cell can be achieved through different designs of the cover.

Weitere Einzelheiten der Erfindung, die insbesondere die Ausbildung der beiden Profilbleche betreffen, sind in den Unteransprüchen angegeben. Die Erfindung wird nachfolgend anhand von 7 in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben und erläutert. Die Figuren der Zeichnung zeigen jeweils einen Teilquerschnitt durch eine Außenwand einer Beton-Raumzelle mit dem angrenzenden, auf dieser Außenwand aufliegenden Bereich eines Flachdaches, dem Lüftungsschlitz zwischen Wand und Dach und unterschiedlichen Ausgestaltungen von Abdeckungen für diese Lüftungsschlitze.Further details of the invention, which relate in particular to the design of the two profiled sheets, are specified in the subclaims. The invention is described and explained in more detail below with reference to 7 exemplary embodiments shown in the drawing. The figures of the drawing each show a partial cross section through an outer wall of a concrete room cell with the adjoining area of a flat roof lying on this outer wall, the ventilation slot between the wall and the roof and different designs of covers for these ventilation slots.

Gleiche oder gleichwirkende Teile sind in allen Ausführungsbeispielen mit gleichen Bezugszeichen versehen.The same or equivalent parts are provided with the same reference numerals in all exemplary embodiments.

Auf einer Außenwand 10 einer Beton-Raumzelle ruht ein Flachdach 11. Zwischen beiden sind entlang des gesamten Umfanges der Raumzelle Lüftungsschlitze 12 ausgespart, und zwar bei den Ausführungsbeispielen gem. Fig. 1 bis 4 aus dem Flachdach 11 und beim Ausführungsbeispiel gem. Fig. 5 aus der Außenwand 10. An der nach außen weisenden Öffnung der Lüftungsschlitze 12 ist eine kanalförmige, um den gesamten Umfang der Raumzelle laufende Abdeckung 13 vorgesehen. Diese Abdeckung 13 besteht aus zwei zusammengeklipsten Profilblechen, nämlich einem ersten Profilblech 14 aus einem ungelochten Blech- oder Kunststoffmaterial und einem zweiten Profilblech 16, 17 aus einem gelochten Material.A flat roof 11 rests on an outer wall 10 of a concrete room cell. Ventilation slots 12 are cut out between the two along the entire circumference of the room cell, in the exemplary embodiments according to FIG. 1 to 4 from the flat roof 11 and according to the embodiment. 5 from the outer wall 10. A channel-shaped cover 13 running around the entire circumference of the room cell is provided at the outward-facing opening of the ventilation slots 12. This cover 13 consists of two clipped profile sheets, namely a first profile sheet 14 made of an unperforated sheet or plastic material and a second profile sheet 16, 17 made of a perforated material.

Das senkrechte Teilstück des Profilbleches 14 ist fluchtend mit der Stirnfläche des Dachsimses 15 des Flachdaches 11 angeordnet und bildet mit dem Dachsims das Gesamtsims der Raumzelle. Das zweite Profilblech 16, 17 schließt die Lüftungsschlitze 12 an deren Außenseite stochersicher ab, wobei die Lochwand 16 jeweils die senkrechte, unmittelbar vor dem nach außen weisenden Endstück der Lüftungsschlitze 12 angeordnete Wand und die Lochwand 17 die waagerechte, wahlweise nach oben oder unten gerichtete Wand des zweiten Profilbleches bildet. Die beiden Lochwände 16 und 17 sind also in Durchströmrichtung hintereinander geschaltet, so daß sich eine besonders große Sicherheit gegen das Eindringen von Staub, Flugschnee oder Kleintieren in den Innenraum der Raumzelle ergibt. Die Löcher der Lochwände 16 und 17 besitzen einen Durchmesser von 2,5 mm und . eine Teilung von 3,5 mm. Der gesamte freie Lüftungsquerschnitt ist so berechnet, daß er zur Entlüftung der Raumzelle ausreicht. Zweckmäßigerweise besteht mindestens die Lochwand 16 aus einer Brandschutzplatte aus einem Harnstoff-Formaldehydharz, die beim Auftreffen heißer Abgase einer Explosionsdruckwelle aus dem Innenraum der Raumzelle aufschäumt und somit zu einer Abkühlung der nach außen strömenden Gase beiträgt.The vertical section of the profiled sheet 14 is aligned with the end face of the roof ledge 15 of the flat roof 11 and forms the overall ledge of the room cell with the roof ledge. The second profiled sheet 16, 17 closes the ventilation slots 12 on the outside thereof poke-proof, the perforated wall 16 each forming the vertical wall arranged directly in front of the outward-facing end piece of the ventilation slots 12 and the perforated wall 17 forming the horizontal, optionally upward or downward wall of the second profiled sheet. The two perforated walls 16 and 17 are thus connected in series in the direction of flow, so that there is a particularly high level of security against the ingress of dust, flying snow or small animals into the interior of the room cell. The holes in the perforated walls 16 and 17 have a diameter of 2.5 mm and. a pitch of 3.5 mm. The total free ventilation cross-section is calculated so that it is sufficient to vent the room cell. Appropriately, at least the perforated wall 16 consists of a fire protection plate made of a urea-formaldehyde resin, which foams up when an exhaust pressure wave of hot explosion occurs from the interior of the room cell and thus contributes to cooling the gases flowing outwards.

Für die Herstellung der Abdeckungen 13 der verschiedenen Ausführungsbeispiele kann stets dasselbe Preßwerkzeug verwendet werden. Dies führt zu einer besonders kostengünstigen Lösung.The same pressing tool can always be used to produce the covers 13 of the various exemplary embodiments. This leads to a particularly inexpensive solution.

Vergleicht man die Ausführungsbeispiele gem. Fig. 1 und 2, so erkennt man, daß die Abdeckungen 13 lediglich um 180° um eine horizontale Querachse gedreht worden sind, so daß im Beispiel gem. Fig. 1 die Lochwand 17 nach unten und im Beispiel gem. Fig. 2 nach oben weist. Damit beim Ausführungsbeispiel gem. Fig. 2 ein ausreichend breiter Strömungsweg für die Abluft nach oben zur Verfügung steht, wurde bei der Herstellung des Beton-Flachdaches 11 lediglich eine Dreieckschiene in die Betonierform eingelegt, so daß die äußere Unterkante des Flachdaches abgeschrägt ist. Dies ist auch beim Ausführungsbeispiel gem. Fig. 3 der Fall. Das Profilblech 14 der dort vorgesehenen Abdeckung 13 weist im Unterschied zu den vorangegangenen Ausführungsbeispielen eine sich nach oben erstreckende Verbreiterung 23 auf, die den Dachsims 15 auf seiner gesamten Höhe abdeckt und seine Oberkante auf der gesamten Breite eines gegenüber der Oberseite erhöhten Randstreifens 24 umgreift. Die Dachoberseite ist bei derartigen Flachdächern stets durch eine in der Zeichnung nicht dargestellte Kunststoffolie gegen eindringende Feuchtigkeit geschützt. Diese Kunststoffolie ist ihrerseits wieder durch eine Kiesbedeckung gegen UV-Einstrahlung bis auf den Randstreifen 24 geschützt, auf dem sich eine Kiesbedeckung nicht halten würde. Deshalb stellt das Ausführungsbeispiel gem. Fig. 3 - wie auch die folgenden Ausführungsbeispiele gem. Fig. 4 und 5 - eine sehr zweckmäßige Ausführungsform dar, weil hier durch die Verbreiterung 23 des Profilbleches 14 gerade der ungeschützte Randstreifen 24 des Flachdaches 11 überdeckt wird.If you compare the embodiments according. 1 and 2, it can be seen that the covers 13 have only been rotated by 180 ° about a horizontal transverse axis, so that according to the example in FIG. Fig. 1, the perforated wall 17 down and in the example gem. Fig. 2 points upwards. So according to the embodiment. Fig. 2 is a sufficiently wide flow path for the exhaust air upwards, only a triangular rail was inserted into the concreting mold in the manufacture of the concrete flat roof 11, so that the outer lower edge of the flat roof is chamfered. This is also in the embodiment. Fig. 3 the case. In contrast to the previous exemplary embodiments, the profiled sheet 14 of the cover 13 provided there has a widening 23 which extends upwards and which covers the roof ledge 15 over its entire height and encompasses its upper edge over the entire width of an edge strip 24 which is raised in relation to the upper side. In such flat roofs, the top of the roof is always protected against the ingress of moisture by a plastic film (not shown in the drawing). This plastic film is in turn protected by a gravel covering against UV radiation up to the edge strip 24, on which a gravel covering would not stick. Therefore, the embodiment according to Fig. 3 - as well as the following embodiments. 4 and 5 - a very useful embodiment, because here the unprotected edge strip 24 of the flat roof 11 is covered by the widening 23 of the profile sheet 14.

Soll wie beim Ausführungsbeispiel gem. Fig. 3 die Abluft nach oben abgeleitet werden, so müssen in der Verbreiterung 23 des Profilbleches 14 Lüftungsöffnungen 25 vorgesehen werden. Beim Ausführungsbeispiel gem. Fig. 4 entfallen diese Lüftungsöffnungen, da hier die Abluft nach unten abgeleitet wird. Ist das Preßwerkzeug zur Herstellung des Profilbleches 14 zweckmäßig aufgebaut, so kann es - wie bereits erwähnt - trotz der Verbreiterung 23 und der Lüftungsöffnungen 25 für sämtliche Profilbleche 14 der verschiedenen Ausführungsbeispiele benutzt werden.Should, as in the embodiment. Fig. 3 the exhaust air are derived upwards, 14 ventilation openings 25 must be provided in the widening 23 of the profile plate. In the embodiment according to Fig. 4 omitted these ventilation openings, since here the exhaust air is discharged downwards. If the pressing tool for producing the profiled sheet 14 is expediently constructed, it can - as already mentioned - be used for all profiled sheets 14 of the various exemplary embodiments, despite the widening 23 and the ventilation openings 25.

Auch beim Ausführungsbeispiel gem. Fig. 5 ist das Dachsims 15 des Flachdaches 11, das hier bündig mit der Außenwand 10 abschließt, durch Blechprofile abgedeckt. An das Profilblech 16, 17 ist ein weiteres Vollblechprofil 20 angesteckt, das zusammen mit dem Profilblech 14 das Gesamtsims der Raumzelle bildet.Also in the embodiment according to Fig. 5 is the roof ledge 15 of the flat roof 11, which is flush here with the outer wall 10, covered by sheet metal profiles. Another solid sheet profile 20 is attached to the profile sheet 16, 17, which together with the profile sheet 14 forms the overall ledge of the room cell.

Bei allen Ausführungsbeispielen können die Fugen zwischen dem Flachdach 11 oder der Außenwand 10 einerseits und der Abdeckung 13 andererseits bedarfsweise mit einer Dichtungsmasse 19 ausgefüllt werden. Bei den Ausführungsbeispielen gem. Fig. 2 bis 5 ist das an einigen Stellen angedeutet. Ferner kann an der nach unten weisenden Lochwand 17 des zweiten Profilbleches ein Schneeabweiser 21 vorgesehen werden (Fig. 1) und schließlich kann an das Profilblech 14 der Abdeckung 13 eine Tropfnase 18 und/oder eine Regenrinne 22 angeformt sein.In all of the exemplary embodiments, the joints between the flat roof 11 or the outer wall 10 on the one hand and the cover 13 on the other hand can be filled with a sealing compound 19 if necessary. In the embodiments according to 2 to 5 this is indicated in some places. Furthermore, a snow deflector 21 can be provided on the downward-facing perforated wall 17 of the second profiled sheet (FIG. 1) and finally a drip nose 18 and / or a rain gutter 22 can be integrally formed on the profiled sheet 14 of the cover 13.

Die Ausführungsformen gem. Fig. 3 bis 5 sind zwar materialaufwendiger als diejenigen gem. Fig. 1 und 2, zeichnen sich aber neben der bereits erwähnten schützenden Überdeckung des Randstreifens 24 durch eine besonders problemlose Befestigung an der Raumzelle aus, da keine Rücksicht auf Fertigungstoleranzen des Flachdaches 11 und/oder der Lüftungsschlitze 12 genommen werden müssen.The embodiments acc. 3 to 5 are more expensive than those according to. 1 and 2, but in addition to the already mentioned protective overlap of the edge strip 24, are distinguished by a particularly problem-free attachment to the room cell, since no consideration must be given to the manufacturing tolerances of the flat roof 11 and / or the ventilation slots 12.

Von besonderem Vorteil ist es auch, daß die Ableitrichtung für die Abgase bei bereits montierten Abdeckungen in einfacher Weise geändert werden kann, indem die Abdeckung 13 gelöst, sodann gedreht und schließlich wieder befestigt wird. Durch diese wahlweise Verwendung der Abdeckung 13 mit nach oben oder unten gerichteter Ableitung der Gase wird auch die Lagerhaltung derartiger Abdeckungen in hohem Maße rationalisiert.It is also of particular advantage that the direction of discharge for the exhaust gases can be changed in a simple manner in the case of covers which have already been fitted, in that the cover 13 is loosened, then rotated and finally fastened again. This optional use of the cover 13 with upward or downward discharge of the gases also rationalizes the storage of such covers to a high degree.

Während bei den Ausführungsbeispielen gemäß Figur 1 bis 5 die Gestaltung der unteren Außenkante des Flachdaches 11 davon abhing, ob die Lüftungsöffnungen der Abdeckung 13 nach oben oder unten weisen sollen, sind bei den Ausführungsbeispielen gemäß Figur 6 und 7 die Formungen der Abdeckungen 13 so gewählt, daß bei völlig gleichem Flachdach 11 sowohl eine Abdeckung 13 mit nach unten weisenden Lüftungsöffnungen als auch eine Abdeckung mit nach oben weisenden Lüftungsöffnungen angebracht werden kann. Der besondere Vorteil dieser Ausführungsbeispiele liegt also darin, daß man erst vorort zu bestimmen braucht, ob eine Abdeckung 13 mit nach unten oder nach oben gerichteter Ableitung der Gase montiert werden soll. Irgendwelche Änderungen an der Form des Flachdaches 11 brauchen bei dieser Wahl nicht vorgenommen zu werden.While in the exemplary embodiments according to FIGS. 1 to 5 the design of the lower outer edge of the flat roof 11 depended on whether the ventilation openings of the cover 13 should face upwards or downwards, in the exemplary embodiments according to FIGS. 6 and 7 the shapes of the covers 13 were chosen so that that with a completely identical flat roof 11, both a cover 13 with downward-pointing ventilation openings and a cover with upward-pointing ventilation openings can be attached. The particular advantage of these exemplary embodiments lies in the fact that it is only necessary to determine on site whether a cover 13 should be installed with the gases directed downwards or upwards. Any changes to the shape of the Flat roofs 11 do not need to be made with this choice.

2. Cabin according to Claim 1, characterised in that the cover (13) is formed from two sheet-metal sections (14, 16, 17), of which the first sheet-metal section (14) consisting of non-perforated material forms the outward-pointing, at least partially vertical wall of the cover and part of the cornice (15, 20) of the flat roof, and the second sheet-metal section (16, 17) consists essentially of a perforated material which covers the ventilation slits so as to guard against poking and which has a free ventilation cross-section sufficient for ventilating the cabin.
3. Cabin according to Claim 1 or 2, characterised in that the two sheet-metal sections (14 ; 16, 17) can be connected to one another by means of clips.
4. Cabin according to any of Claims 1 to 3, characterised in that the first sheet-metal section (14) has an extension (23) which covers the cornice (15) for its entire height and which engages over the top edge of the latter preferably over the entire width of an edge strip (24) raised relative to the roof top.
5. Cabin according to any of the preceding claims, characterised in that a gutter (22) and/or a drip edge (18) is formed on the sheet-metal section (14).
6. Cabin according to any of the preceding claims, characterised in that the gap between the cabin and the cover (13) is filled at least over some of its depth with a sealing material (19).
7. Cabin according to any of the preceding claims, characterised in that the perforated material has holes with a diameter of preferably 2.5 mm.
8. Cabin according to any of the preceding claims, characterised in that the perforated material consists of a fireproof board, especially a board composed of a urea/formaldehyde resin, which foams at temperatures above 150°.
9. Cabin according to any of the preceding claims, characterised in that a snow guard (21) is arranged on the second sheet-metal section (16, 17).
10. Cabin according to any of the preceding claims, characterised in that the recesses for the ventilation slits (12) are provided exclusively in the flat roof (11).
11. Cabin according to any of Claims 1 to 9, characterised in that the recesses for the ventilation slits (12) are provided exclusively in the outer walls (10).
