Description
Ein Teil der neuen Stahlbetondeckenko:nstruktionen in Wohnräumen und zum Teil auch in Industriebauten hat die hochgestellten Erwartungen bezüglich Schall- und Wärmedämmung und der einfachen Herstellungsbauweise nur in seltenen Fällen erfüllt. Oft hat man den oberen Abschluß der Stahlbetondecken in kraftschlüssigen Zusammenhang mit den eingebauten Rippen gebracht und so den Schall über die Decken und Wände zu den angrenzenden Räumen geleitet, was als ein großer Übelstand empfunden wird. Bei vielen Konstruktionen hat .man jedoch eine gute Dämmwirkung dadurch zu erreichen versucht, daß man unter den tragenden Teilen ,der Decken und auch zwischen den Tragrippen Holzbeton einbaute. Man hat aber bei einzelnen bisher bekanntgewordenen Konstruktionen den Stahlbetonfußboden als Druckplatte ausgenutzt und mit :den Stegen der Betonrippen in kraftschlüssige Verbindung gebracht und so dem Schall eine direkte Brücke nach den angrenzenden Räumen gebaut. Bei einzelnen Konstruktionen, bei denen Holzbeton als D.ämmstoff verwandt wurde, war es. erforderlich, eine Einschalung vorzunehmen, sei es, um den Holzbeton aufbringen zu können, oder die Holzbetonblöcke, die man: zur Bildung der Lehren bei der Ausführung von Rippendecken verwandte, zu unterstützen. Es ist eher wünschenswert, eine Stahlbetondeckenkonstruktion auszuführen, welche -die vorbeschriebenen Mängel nicht aufweist, welche insbesondere eine D@ämmwirkung in bisher nicht gekannter Weise hat und einfach auszuführen ist.Part of the new reinforced concrete ceiling structures in living quarters and partly also in industrial buildings, the high expectations regarding noise and thermal insulation and the simple manufacturing method are only met in rare cases. Often one has the upper end of the reinforced concrete ceiling in a positive connection with the built-in ribs and so the sound over the ceilings and walls led to the adjoining rooms, which is perceived as a great evil. In many constructions, however, one has to achieve a good insulating effect in this way tries to get under the load-bearing parts, the ceilings and also between the support ribs Built in wood concrete. But one has with individual constructions that have become known so far the reinforced concrete floor used as a pressure plate and with: the webs of the concrete ribs brought into force-fit connection and thus a direct bridge after the sound built in the adjacent rooms. For individual constructions where wood-concrete When insulation material was used, it was. necessary to make a shuttering, be it to be able to apply the wood-concrete, or the wood-concrete blocks that you can: to support the formation of the gauges related to the execution of ribbed ceilings. Rather, it is desirable to have a reinforced concrete ceiling structure which -Does not have the defects described above, which in particular have an insulating effect in a previously unknown way and is easy to carry out.
In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäß ausgebildeten Decke dargestellt (Fig. i, 2 und: 3). Die Decke nach Fig. i stellt die einfachste Ausführungsweise einer Stahlbetonträgerdecke mit aus bewehrtem Hälzbeton bestehenden Füllkörpern dar und besitzt eine hohe Dämmwirkung. Die Ausführung wird vorgen.ommen .unter Verwendung der .allgemein bekannten vorgespannten I-förmiigen Betonträger, welchen hier allein ,die Aufgabe zufällt, sofort nach ihzer Verlegung die gesamten Traglasten aus Eigengewicht und Nutzlast zu übernehmen. Man verlegt .diese vorgespannten I-förmigen Stahlbetonträger im üblichen Abstand voneinander, fügt in die Zwischenräume an Stelle der bisher gebräuchlichen Hohlkörper aus B.imsbeton einen beschlossenen, leicht bewehrten Holzblockst.ein, der auf den Deckenträgern aufsitzt, so ein, daß zwischen Blockstein und Deckenträger noch eine Vergußfu.ge verbleibt. Die Unterkante des Holzbetonblocksteines reicht bis etwa 2 cm unter den Betonträger, und, seine Oberkante schneidet mit der Oberkante des Deckenträgers ab (Fig. i bis 3).In the drawing is an embodiment of the inventively designed Cover shown (Fig. I, 2 and: 3). The ceiling according to Fig. I represents the simplest Execution of a reinforced concrete girder ceiling made of reinforced concrete Packing bodies and has a high insulating effect. The execution is being carried out .using the generally known prestressed I-shaped concrete girders, to whom alone the task falls, immediately after their relocation the whole To take over loads from dead weight and payload. These prestressed ones are laid I-shaped reinforced concrete girders at the usual distance from each other, inserts into the gaps instead of the previously used hollow bodies made of B. imsbeton a decided, lightly reinforced wooden blocks that sit on the ceiling beams so that A grouting joint remains between the block and the ceiling beam. The bottom edge of the wood-concrete block extends to about 2 cm below the concrete beam, and, his The top edge cuts off with the top edge of the ceiling beam (Fig. I to 3).
Die Untersicht des vorgespannten Betonträgers ist mittels Holzdübel mit einer Holzfaserplatte a verkleidet, so daß die gesamte Deckenuntersicht aus gleichartigem Material besteht. Nachdem der Fugenfverguß von der Obersicht der Decke her vor-.genommen ist, wird über die gesamte Deckenfläche, an den Wänden einige Zentimeter hochgehend, eine Isolierschicht b aus druckfester Pappe oder anderen isolierenden Dämmstoffen aufgebracht und hierauf schwimmend eine Stahlbetonplatte c entsprechender Stärke aufbetoniert. Die vorbezeichneten Holzblocksteine können auch einseitig mit einer Nase versehen werden, welche den Unterflansch des Deckenträgers so wberdieckt, daß ebenfalls eine Verkleidung aus gleichem Material erzielt wird (Fig. 3 und 4). Es ist hierbei erforderlich, der Nase des Blocksteines eine zusätzliche Bewehrung zu fiebern, um sie vor Bruch zu bewahren. Es können auch Holzbetonhohlkörper zum Einbau gelangen, die in ihrer Formgebung den bekannten Hohlkörpern aus anderen Baustoffen ähnlich sind (Fig. 4).The soffit of the prestressed concrete beam is made using wooden dowels clad with a fibreboard a, so that the entire ceiling soffit from consists of similar material. After the joint grouting from the top of the ceiling is made before, is over the entire ceiling surface, some on the walls Raising centimeters, an insulating layer b made of pressure-resistant cardboard or other insulating material applied and a reinforced concrete slab floating on it c concreted on top of the appropriate thickness. The aforementioned wooden blocks can can also be provided with a nose on one side, which the lower flange of the ceiling beam in such a way that a cladding made of the same material is also achieved (Figures 3 and 4). It is necessary here to give the nose of the block an additional Fevering reinforcement to keep it from breaking. Hollow wood-concrete bodies can also be used get to the installation, the shape of the well-known hollow bodies from others Building materials are similar (Fig. 4).
Eine aus Fertigbauteilen mit Isolierung und- mit auf ihr schwimmenden Stahlbetonfußbodenplatte hergestellte Decke leitet -den Schall nicht mehr in die angrenzenden Räume und verhindert den Wärmedurchgang ganz wesentlich; ihre Herstellung ist einfach und erfordert geringen Arbeitsaufwand.One made of prefabricated components with insulation and with floating on it Reinforced concrete floor slab produced ceiling no longer conducts the sound into the adjoining rooms and prevents the passage of heat quite significantly; their manufacture is simple and requires little labor.
