Description

Verfahren zur Herstellung hochverdichteter, mit einem Schall- bzw. Wärmeschutz versehener Betonfertigteile Alle Betonfertigteile aus geschlossenem, hochverdichtetem Beton haben die Eigenschaft, Schall und Wärme verhältnismäßig gut zu leiten; meist ist diese Eigenschaft unerwünscht. Auch ein Verputzen solcher Betonfertigteile ist schwierig, da der Putz an den glatten, hochharten Flächen ohne besondere Vorkehrungen schlecht haftet.Process for the production of high-density, with a sound or Precast concrete elements provided with thermal insulation All precast concrete elements made of closed, Highly compressed concrete has the property of sound and heat relatively well to direct; usually this property is undesirable. Also plastering such precast concrete parts is difficult because the plaster on the smooth, extremely hard surfaces without special precautions badly adheres.

Eieide Nachteile werden erfindungsgemäß dadurch vermieden, daß Betonfertigteile aus geschlossenem, hochverdichtetem Beton mit einem Isolierstoff von grober Oberflächenbeschaffenheit versehen «erden, dessen Verbindung mit dem geschlossenen Beton nur durch das Abbinden des Betons sofort bei der Herstellung des Teiles erfolgt. Erfindungsgemäß charakteristisch ist, daß durch ein besonderes Verfahren, z. B. Vibrationsverdichtung, bei der Herstellung der Betonteile ein starkes Eindringen der sonst geschlossenen Betonmasse in die Isoliermasse erreicht wird. Das fertige Betonteil hat also eigentlich drei Schichten: i. die geschlossene Betonschicht, 2. die Übergangsschicht Beton -h- Isolierstoff, 3. die Isolierschicht.Both disadvantages are avoided according to the invention in that precast concrete parts Made of closed, high-density concrete with an insulating material with a rough surface finish provided «, its connection with the closed concrete only through the setting of the concrete takes place immediately when the part is manufactured. According to the invention characteristic is that by a special process, e.g. B. Vibration Compaction, in the manufacture the concrete parts a strong penetration of the otherwise closed concrete mass into the Isolating mass is achieved. So the finished concrete part actually has three layers: i. the closed concrete layer, 2. the transition layer concrete -h- insulating material, 3. the insulating layer.

Besondere Bedeutung hat das Verfahren für die Herstellung von Stahlbetonhohldielen, vielfach auch Stegzementdielen genannt, da die spätere Anbringung einer besonderen Isolierschicht an einer aus Stahlbetonhohldielen gebildeten Decke sehr kostspielig ist. Die Dielen werden zweckmäßig so gefertigt, daß die Isolierschicht an den Enden der Diele um so viel kürzer ist, daß die Diele auf den Flanschen der Deckenträger nur mit der tragenden geschlossenen Stahlbetonschicht aufliegt.The process is of particular importance for the production of reinforced concrete hollow floorboards, often also called bar cement floorboards, as the later attachment of a special one Insulating layer on a ceiling made of hollow reinforced concrete planks is very expensive is. The boards are expediently manufactured in such a way that the insulating layer is at the ends the plank is so much shorter that the plank on the Flanges the ceiling girder rests only with the load-bearing closed reinforced concrete layer.
