Description

Wiederherstellung von durch Brand oder auf andere Art beschädigten Hohlkörperdecken Man hat mit Vorliebe bei der Herstellung von Wohn- und Geschä ftshäusern der Hohlkörperdecke in der Stahllictonliauweise den Vorzug gegeben, weil die tragenden Teile derselben nicht unnötig hoch belastet werden und eine vorzügliche Dätnin- wirkung vorliegt. Inn Verlauf des Bombenkrieges sind durch Brand in großem Unifatige derartige Decken stark in. 'Mit- leidenschaft gezogen worden. Der Befund ist in der 122-e1 so, dah sich an den Deckenuntersichten tiefe Öffnungen zeigen, die durch Abplatzen des unteren Teiles des Hohlkörpers entstanden sind. Außerdem liegen die in die Tragrippen einbetonier- ten Armierungen frei und besitzen nicht mehr die kraftschlüssige Verbindung mit (lern Betoi>,druck- gurt der Deckenktiiistrtiktio>n. Man half sich, indem tnan derartige Decken voii unten säuberte, die Lisen von Rost befreite und alsdann einen Betonspritzputz aufbrachte, wobei die nicht unbeträchtlichen Hohl- räume, welche die abgeplatzten Hohlkörper oder Hohlsteine aufzeigen, einfach mit zugespritzt wor- den. Dieses Verfahren bedingt einen wesentlich größeren Material- und Arbeitsaufwand als er- forderlich, und es hat zudem den. Nachteil, claß eine wesentliche Erhöhung des Eigengewichtes der Decke eiitstelit und der Durchgang von Schall und Tempe- ratur erhöht wird. Der Wert derartig wiederherge- stellter Dcclken sinkt auf den, welche gewöhnliche Stahlbetonplattendecken aufweisen, herab. Bei (lein erfindungsgemäß nachfolgend geschil- derten Vorgehen bei der Wiederherstellung von Hohlkörperdecken im Spritzputzverfaliren werden vorstehend geschilderte Nachteile vermieden. Es werden sogar die früheren guten Eigenschaften der Decke in bezug auf ihre Dä mniwirkung Nviederge- w<mnen. und (las ursprüngliche der statischen Be- rechnung zugrunde gelegte Eigengewicht wird nicht unnötig erhöht.Restoration of hollow core slabs damaged by fire or in any other way One has a preference in the production of Residential and commercial buildings of the hollow core ceiling given preference in the Stahllictonliau way, because the load-bearing parts of the same are not unnecessary are highly stressed and an excellent diet effect exists. Inn course of the bombing war are by fire in large unifatige such blankets strongly in. been drawn into passion. The finding is in the 122-e1 so , then on the ceiling soffit show deep openings caused by flaking of the lower part of the hollow body. In addition, the concreted in the support ribs are ten reinforcements free and no longer have the frictional connection with (learn Betoi>, pressure Belt of the ceiling hinges. One helped oneself by tnan cleaned such blankets from below, the pilaster strips from rust and then a concrete spray plaster applied, whereby the not inconsiderable hollow spaces, which the chipped hollow body or Point out hollow stones, simply injected with the. This procedure requires an essential greater material and labor costs than required, and it also has the. Disadvantage, that's one significant increase in the weight of the ceiling eiitstelit and the passage of sound and temperature rature is increased. The value thus restored Asked Dcclken sinks to what is common Have reinforced concrete slab ceilings down. In the case of (lein according to the invention described below the correct procedure for restoring Hollow body ceilings are covered in spray plaster the disadvantages outlined above avoided. It become even the earlier good qualities of the Ceiling with regard to its insulating effect. w <mnen. and (read the original of the static load The dead weight on which the calculation is based is not unnecessarily increased.

Auf einfache Art und Weise wird wie folgt verfahren: Die an den zerstörten Hohlkörpern nach unten frei liegenden Öffnungen werden entweder durch Polster ausgefüllt, deren Äußeres aus Dachpappe o. dgl. besteht und deren Inneres einen leichten Isolierstoff, wie Glaswolle, Torf o. dgl., enthält, oder es werden in die Hohlräume runde oder eckige Rohre aus Pappe oder ähnlichem Material eingeführt, die keine Füllung erhalten. In beiden Fällen bleibt nur der Steg der Stahlbetontragrippen mit den Trageisen frei. Die einzubauenden ElementeProceed as follows in a simple manner: The one to the destroyed Hollow bodies exposed at the bottom are either filled with cushions, the outside of which consists of roofing felt or the like and the inside a light insulating material, such as glass wool, peat or the like. Contains, or there are round or in the cavities angular tubes made of cardboard or similar material are introduced which do not contain any filling. In both cases, only the web of the reinforced concrete support ribs with the support iron remains free. The elements to be built in
