BeschreibungDescription
Gegenstand der Anmeldung ist ein Fußboden-Trockenestrich in Platten- oder Dielenform, geeignet für die Verlegung auf Warmwasser-Fußboden-Heizungsanlagen.The subject of the application is a dry floor screed in the form of panels or planks, suitable for installation on hot water underfloor heating systems.
Erzeugnisse aus Holz oder Holzwerkstoffen haben von Natur aus wärmedämmende Eigenschaften.Products made of wood or wood-based materials have naturally insulating properties.
Zum Beispiel hat eine 22 mm starke handelsübliche Fußboden-Verlegeplatte auf Spanplattenbasis mit der Wärmeleitzahl &lgr; o, 12 W/mK den Wärmedurchlasswiderstand von 1//1 o,18 m K/W. Dieser Wert beinhaltet nicht den noch aufzubringenden eigentlichen Gehbelag.For example, a 22 mm thick commercially available chipboard-based flooring board with a thermal conductivity of λ o, 12 W/mK has a thermal resistance of 1//1 o,18 m K/W. This value does not include the actual floor covering that still needs to be applied.
Lt. Normentwurf DIN 4725 sind für Warmwasser-Fußbodenheizungen nur solche Bodenkonstruktionen geeignet, deren Wärmedurchlasswiderstand den Grenzwert, das ist der Wert des gesamten Bodenaufbaus, einschl. Gehschicht, von 1/4. o,15 m2 K/W nicht übersteigt.According to the draft standard DIN 4725, only those floor constructions are suitable for hot water underfloor heating whose thermal resistance does not exceed the limit value, that is the value of the entire floor structure, including the walking layer, of 1/4 o.15 m 2 K/W.
Das vorbeschriebene Beispiel einer 22 mm starken Fußboden-Verlegeplatte übertrifft dieses Limit um 2o ~M und ist deshalb in der handelsüblichen Form für diesen Zweck nicht geeignet.The example of a 22 mm thick flooring board described above exceeds this limit by 2o ~M and is therefore not suitable for this purpose in its commercially available form.
Da auf der Unterseite der Platten oder Dielen metallische Stifte, insbesondere in Form von Nagelplatten, wie solche im Holzbau verwendet werden, eingebracht / eingepresst sind, verändert sich hierdurch die Wärmeleitzahl entsprechend dem Volumen der Stahlnägel bzw. der metallischen Stifte nach dem prozentualen Anteil innerhalb des gesamten Volumens der Platten oder Dielen.Since metal pins, particularly in the form of nail plates such as those used in timber construction, are inserted/pressed into the underside of the panels or planks, the thermal conductivity changes according to the volume of the steel nails or metal pins according to the percentage within the total volume of the panels or planks.

» Äärmeleitzahl für die Berechnungen = &lgr; 1,o2 W/m K.» Thermal conductivity for the calculations = &lgr; 1,o2 W/m K.
Der Wärmedurchlasswiderstand einer Platte / Diele auf Holzwerkstoffbasis in 22 mm Dicke mit unterseitig eingepressten, ca. 22 mm langen Stahlnägeln, deren Anteil am Gesamtvolumen der Platten /Dielen 1,?4 Io beträgt, hat den Wert: o,o22 m ./. 1,o2 - 1//L o,o21 m2 K/W.The thermal resistance of a board/plank made of wood material with a thickness of 22 mm and with steel nails pressed into the underside, approximately 22 mm long, whose share of the total volume of the board/plank is 1.4 Io , has the value: o.o.22 m ./. 1.o2 - 1//L o.o.21 m 2 K/W.

B. aus Nadelholz mit der Wärmeleitzahl &lgr; &ogr;,29 W/m K, (siehe: Hans W.

When using solid wood instead of wood-based panels, e.g. with upright fibers like headboards, wooden paving or vertical slats, e.g. made of softwood with a thermal conductivity of λ ω,29 W/m K (see: Hans W. Bobran, "Handbook of Building Physics"), the thermal resistance is calculated as follows: Assumed volume fraction of steel nails 1.7^ %* - Thermal conductivity of λ 58.oo W/m K χ 1.74 % » o.9o48 Volume fraction of softwood 98.26 #, « Thermal conductivity of λ ω,29 W/m K χ 98.26 &idigr;» · χ,2849

In beiden Fällen verbleibt genügend Spielraum für die nachfolgende Gehschicht, die aus Parkett, Teppichboden oder jedem anderen Bodenbelag bestehen kann.In both cases, there is enough space for the subsequent walking layer, which can consist of parquet, carpet or any other floor covering.
Parkettdielen aus massiver Eiche oder einer Sperrholztragschicht, versehen mit einer Oberschicht aus lache, z.B. in 12 mm Dicke, erhöhen den Wärmedurchlasswiderstand des Bodenaufbaus um 1//L 0,06 m K/W auf &Lgr;/&Lgr;. o,o81 bzw. 1//L o,o78 m2 K/Ä.Parquet floorboards made of solid oak or a plywood base layer, provided with a top layer of lache, e.g. 12 mm thick, increase the thermal resistance of the floor structure by 1//L 0.06 m K/W to λ/λ. o,o81 or 1//L o,o78 m 2 K/Ä.
Beide Bodenaufbau-Systeme liegen weit unter dem Limit It. Normentwurf DIN 4-725 mit 1. um 46 70 und 2. um 48 %. Both floor construction systems are well below the limit according to draft standard DIN 4-725 with 1. around 46 70 and 2. around 48 %.
