Abstract

Cette dalle en console comporte une assise composée de poutres en béton (1) et de briques d'argile (2) sur laquelle la chape en béton (3) est coulée. L'armature consiste en un matériau composite renforcé par fibres résistant à la corrosion, les barres d'armature étant disposées aussi bien dans la chape en béton (3) que dans les poutres en béton (1).This cantilevered slab comprises a seat composed of concrete beams (1) and clay bricks (2) on which the concrete screed (3) is poured. The reinforcement consists of a fiber-reinforced composite material resistant to corrosion, the reinforcing bars being arranged both in the concrete screed (3) and in the concrete beams (1).

Description

Thermisch unterteilte Kragplatte mit einer den üeberbeton tragenden vorfabrizierten.) kombinierten Beton— ZiegelplatteThermally subdivided cantilever slab with a pre-fabricated concrete-bearing combined concrete-tile slab
Heber die Kauswand vorstehende Kragplatten, wie sie insbesondere für Balkonböden verwendet werden, bestehen üblicherweise aus mit Stahl armiertem Beton. Dies ergibt bei den verlangten Pestigkeitεan orderun¬ gen sehr gewichtige Konstruktionen. Der bei Stahlanaierung bestehenden Korrosionsge ahr ist dabei besondere Beachtung zu schenken. Ein grosser Nachteil dieser bekannten Platten ist auch, dass sie als ein vom Aussen- in den Innenraum führendes Element durch die hohe Wärme¬ leitfähigkeit von stahl- armiertem Beton beträchtliche Wärmeverluste verurschen. Dies ist heute bei den allgemeinen Bestrebungen einer sorgfältigen Wärmeiεolation von Gebäuden nicht mehr tragbar.The cantilever slabs protruding from the chewing wall, as are used in particular for balcony floors, usually consist of steel reinforced with concrete. This results in very weighty constructions for the required pesticides. Particular attention should be paid to the risk of corrosion existing in steel renovation. A major disadvantage of these known plates is also that, as an element leading from the outside into the interior, they cause considerable heat losses due to the high thermal conductivity of steel-reinforced concrete. Today, this is no longer viable in the general efforts to carefully insulate buildings from heat.
Die Erfindung stellt sich die Aufgabe eine Kragplatte zu schaffen, welche die oben erwähnten Nachteile vermeidet. Die wesentlichen Merk¬ male deε Erfindungεgegenstandeε ergeben sich aus dem Patentanspruch.The invention has for its object to provide a cantilever plate which avoids the disadvantages mentioned above. The essential features of the subject matter of the invention result from the patent claim.
Anhand der Zeichnung wird ein Ausführungsbeispiel der Erfindung näher erläutert.An exemplary embodiment of the invention is explained in more detail with reference to the drawing.
Die dargestellte Kragplatte für eine Ealkon ragt über die Kauswand 8 freitragend hinaus.- Der üeberbeton 3 der Platte ist auf eine vor¬ fabrizierte, kombinierte Ziegel- Betonplatte 1,2 aufgegossen. Letztere besteht aus den Ton- Bippensteinen 2 und den Deckenbalken 1, welch letztere mit Faεerverbundwerkstoff- Kabeln 9 armiert sind. Weitere Armierungen 4 sind im Üeberbeton 3 eingebracht, wobei zu¬ sätzlich auch noch ein Gittergewebe 5 als Armierung vorgesehen sein kann. Pur all diese Armierungen 4,5.9 werden vorzugsweise Paser¬ verbundwerkstoff- Kabel aus Aramid oder einem Kohlenεtoffaser- oder glasfaserverstärktem (CFCC,GPK) Verbundwerkstoff verwendet, d.h. auf jeden Fall ein Material, das neben einer vernachlässigbaren Wärmeleitfähigkeit auch keiner Korrosion unterworfen ist. Je nach den gestellten mechanischen Anforderungen und der Werkstoffart wird die Armierung mit Vorspannung oder schlaff eingebaut angewendet, erstereε insbesondere bei Aramid, letzteres bei C_?CC. Die Ton- Eippensteine 2 sind über die ganze Plattenlänge durchlaufend, ebenso auch die als Oberarmierung dienenden, die Zugspannung aufneh¬ menden Kabel 4. Durch die nachfolgend beschriebene Ausbildung wird eine thermische Trennung zwischen innerem und äuεεerem Plattenteil erreicht. Der üeberbeton 3 iεt durch einen Iεolationskern 6 aus Kunststoff im Bereich der Hauswand 8 unterteilt, ferner sind die Deckenbalken 1 durch druckbeständige Kunεtεtoffplatten 7 in zwei Abschnitte geteilt. Ein Wärmefluss vom Aussen- in den Innenraum kann somit nur durch die Ton- Eippensteine 2 und die aus Verbundwerk¬ stoff bestehenden Armierungen 4 und 9 erfolgen, all diese Elemente sind sehr schlechte Wärmeleiter. Um eine aus gleichem Katerial beste¬ hende Plattenunterseite zu erhalten, können die Deckenbalken 1 mit einen Tonschuh 10 versehen werden.The cantilever plate shown for an Ealkon projects cantilevered beyond the chewing wall 8. The over-concrete 3 of the plate is poured onto a prefabricated, combined brick-concrete plate 1, 2. The latter consists of clay boulder stones 2 and ceiling beams 1, the latter of which are reinforced with fiber composite material cables 9. Additional reinforcements 4 are introduced in the over-concrete 3, wherein a mesh fabric 5 can also be provided as reinforcement. For all of these reinforcements 4, 5, 9, fiber composite cables made of aramid or a carbon fiber or glass fiber reinforced (CFCC, GPK) composite material are preferably used, ie in any case a material which, in addition to a negligible thermal conductivity, is also not subject to corrosion. Depending on the mechanical requirements and the type of material, the reinforcement with pre-stress or slack is used, the former in particular with aramid, the latter with C_? CC. The clay Eippenstein 2 are continuous over the entire length of the plate, as are the cables 4 serving as upper armouring and absorbing the tensile stress. The design described below achieves thermal separation between the inner and outer plate part. The over-concrete 3 is divided by an insulation core 6 made of plastic in the area of the house wall 8, and the ceiling beams 1 are divided into two sections by pressure-resistant plastic plates 7. A heat flow from the outside into the interior can thus only take place through the clay cliffs 2 and the reinforcements 4 and 9 consisting of composite material, all of these elements are very poor heat conductors. In order to obtain an underside of the panel consisting of the same material, the ceiling beams 1 can be provided with a clay shoe 10.
Durch die beschriebene Ausbildung werden oben in der Zugzone die Kräfte durch die Paserverbundkabel 4 aufgenommen, während die Druckzone unten durch die Ton- Ziegelelemente gebildet ist. Due to the design described, the forces are absorbed by the fiber composite cable 4 in the tension zone at the top, while the pressure zone is formed at the bottom by the clay-brick elements.
