Description

Maßnahmen zur Verbesserung der Wärmedämmung von Hohlblocksteinen sind seit Jahrzehnten in der Patentliteratur aller Länder beschrieben und haben zu einem beträchtlichen Teil Eingang in die Baupraxis gefunden. Als zielführende Maßnahme, die Wärmedämmung von Hohlblocksteinen zu verbessern, hat sich unter anderem das Prinzip rücklaufender Wärmewege erwiesen. Hierbei werden die senkrecht zum Wärmefluß durch eine Hohlblock- wand verlaufenden Steinstege soweit aus der Wandebene verschwenkt, daß sich der Weg des Wärmeflusses durch die Steinstege merklich verlängert. Jener Anteil des Gesamt-Wärmeflusses durch die Wand, der auf den Wärmedurchgang durch das Steggitter der Hohlblocksteine entfällt, wird durch diese Maßnahme verringert. Mehrere Patente, u.a. AT-PS 278.319 und 329.836 beziehen sich auf eine derartige Maßnahme im Zusammenhang mit besonderen Ausbildungsformen der Stege.Measures to improve the thermal insulation of hollow blocks have been described in the patent literature of all countries for decades and have found their way into construction practice to a considerable extent. The principle of returning heat paths has proven to be a targeted measure to improve the thermal insulation of hollow blocks. Here, the stone webs running perpendicular to the heat flow through a hollow block wall are pivoted so far out of the wall plane that the path of the heat flow through the stone webs is noticeably extended. This measure reduces the proportion of the total heat flow through the wall that is due to the heat transfer through the web grid of the hollow blocks. Several patents, e.g. AT-PS 278.319 and 329.836 refer to such a measure in connection with special forms of training the webs.

Gleichfalls in der Patentliteratur enthalten ist die darüber hinaus gehende Maßnahme, auch die parallel zum Wärmefluß liegenden Stege durch Knickung zu verlängern, um nochmals den Weg des Wärmeflusses zu verlängern.Also included in the patent literature is the additional measure to extend the webs lying parallel to the heat flow by kinking, in order to lengthen the path of the heat flow again.

Alle diese Maßnahmen berücksichtigen jedoch nicht die Tatsache, daß bei Wänden aus Hohlblocksteinen, sei es aus Beton, gebranntem Ziegel o.dgl., nur der geringere Teil der Wärme tatsächlich durch das Steg-Gitter fließt.However, all these measures do not take into account the fact that in the case of walls made of hollow blocks, whether made of concrete, fired brick or the like, only the smaller part of the heat actually flows through the web grid.

Der größere Teil nimmt seinen Weg etwa parallel zum Wärmefluß durch die hintereinander liegenden Stege und Luftzwischenräume, also durch ein abstrakt als Luft-Steg-Paket zu bezeichnendes System. Um hier den Wärmefluß erfolgreich zu verringern, bedarf es neben entsprechender niedriger Wärmeleitzahlen des Stegmaterials vor allem Maßnahmen im Bereich der zwischen den Stegen befindlichen Luftzwischenröume.The greater part takes its way approximately parallel to the heat flow through the webs and air gaps one behind the other, i.e. through a system that can be abstractly called the air-web package. In order to successfully reduce the heat flow here, in addition to correspondingly low thermal conductivities of the web material, it is above all necessary to take measures in the area of the air spaces between the webs.

Inhalt der vorliegenden Erfindung ist nun eine neuartige Ausbildung des Zwischenraumes zwischen benachbarten, senkrecht zum Wörmefluß liegenden Stein-Stegen, mit dem Ziel einer maximalen Verringerung des Wärmeflusses durch das Luft-Steg-Paket. Es sollen also die parallel zum Wärmefluß - 1 - liegenden Stein-Stege - 4 - einen derart geknickten Verlauf aufweisen, daß jeweils benachbarte Stege zu einer in der Mitte zwischen ihnen liegenden Symmetrieebene - 3 - spiegelbildliche Form besitzen. An den Stellen größten Abstandes voneinander sind diese Stege sodann von etwa parallel zum Wärmefluß laufenden Verbindungsstegen verbunden, die entweder einfach - 5 - oder mehrfach - 6 - geknickt sind.The content of the present invention is now a novel design of the space between adjacent stone webs lying perpendicular to the flow of the river, with the aim of maximally reducing the heat flow through the air-web package. Thus, the stone webs - 4 - lying parallel to the heat flow - 1 - should have such a bent course that adjacent webs have a mirror-image shape to a plane of symmetry in the middle between them - 3. At the points of greatest distance from one another, these webs are then connected by connecting webs running approximately parallel to the heat flow, which are either single - 5 - or multiple - 6 - kinked.

Parallel zu den Symmetrieebenen - 3 - sind nun erfindungsgemäß von Verbindungssteg - 5 - oder - 6 - zu Verbindungssteg - 5 - oder - 6 - reichende, an diesen eng anliegende Platten aus hochisolierendem Material - 8 - angeordnet. Da derartige Platten in aller Regel parallele Begrenzungsflächen aufweisen, entstehen durch die erfindungsgemäße Anordnung der Platten zwischen diesen und den Stegen -4 - keilförmige Luftschichten - 9 -. Diesekeilförmigen Luftschichten, auf deren besondere Eigenschaften tieferstehend noch eingegangen wird, werden auch an ihrer dünnsten Stelle - 9.2 - durch an den Stegen - 4 - angeordnete, kleine Distanzrippen mit etwa rechteckigem - 10 - oder z.B. dreieckigem - 11 - Querschnitt auf einem Dickenmaß größer als Null gehalten.Parallel to the planes of symmetry - 3 -, according to the invention, from the connecting web - 5 - or - 6 - to the connecting web - 5 - or - 6 - extending, closely fitting plates made of highly insulating material - 8 - are arranged. Since such plates generally have parallel boundary surfaces, the arrangement of the plates according to the invention between them and the webs results in -4 - wedge-shaped air layers - 9 -. These wedge-shaped layers of air, whose special properties will be discussed in more detail, are also at their thinnest point - 9.2 - arranged on the webs - 4 - small spacing ribs with an approximately rectangular - 10 - or e.g. triangular - 11 - cross section kept to a thickness greater than zero.

Durch diese erfindungsgemäße Ausbildung entsteht anstelle eines Luftraumes zwischen den Stegen -4 - ein Luft-Isoliermaterial-Luft-System mit bei geeigneter Dimensionierung signifikant niedrigerer Wärmeleitzahl als die des reinen Isoliermaterials.By means of this design according to the invention, instead of an air space between the webs -4, an air-insulation material-air system is created with a suitably dimensioned significantly lower coefficient of thermal conductivity than that of the pure insulation material.

Der besondere Wert der erfindungsgemäßen keilförmigen Luftschichten liegt ferner darin, daß neben den Stegen - 5 - oder - 6 - der dickste Teil - 9.1 - der Luftschicht zu liegen kommt, der infolge seines höheren Wärmedurchlaßwiderstandes einen Wärmefluß" kurzschluß" zwischen den Stegen -4 - und - 5 - (bzw. - 6 -) erschwert.The special value of the wedge-shaped air layers according to the invention lies in the fact that in addition to the webs - 5 - or - 6 - the thickest part - 9.1 - the air layer comes to lie, which due to its higher thermal resistance has a heat flow "short circuit" between the webs -4 - and - 5 - (or - 6 -) difficult.

Weiters ist als Folge der typischen Eigenschaften von Luftschichten die mittlere Wärmedämmung der keilförmigen Luftschicht - 9 - größer, als wenn letztere von parallelen Flächen entsprechend mittleren Abstandes begrenzt wären.Furthermore, as a result of the typical properties of air layers, the average thermal insulation of the wedge-shaped air layer - 9 - is greater than if the latter were delimited by parallel surfaces corresponding to the average distance.

Dieser Effekt ist umso größer, je niedriger die Strahlungskonstante der Isolierplattenoberfläche ist.The lower the radiation constant of the surface of the insulating plate, the greater this effect.

Die letzte erfindungsgemäße Maßnahme zur Verringerung des Wärmedurchganges durch das Luft-Steg-Paket ist der Verzicht auf die üblicherweise stets zum einseitigen Abschluß der Hohlräume von Hohlsteinen angeordneten Deckel oder Böden. Diese sind normalerweise immer erforderlich, damit der zum Vermauern der Hohlblocksteine dienende Mörtel der Lagerfuge nicht in die Hohlräume geraten und .diese ausfüllen kann.The last measure according to the invention for reducing the heat transfer through the air-web package is to dispense with the lids or bases which are usually always arranged for one-sided closure of the cavities of hollow stones. These are normally always necessary so that the mortar of the bed joint, which is used to block the hollow blocks, cannot get into the cavities and fill them.

Bei der erfindungsgemäßen Ausbildung ist die Anordnung derartiger Deckel. oder Böden nicht erforderlich, da die zwischen isoleirplatten - 8 - und Stegen -4 - liegenden, keilförmigen Luftschichten - 9 - an ihrer jeweils dicksten Stelle - 9.1 - jenes Maß - 12 -nicht überschreiten, welches noch ein Hineinfließen von Lagerfugenmörtel unmöglich macht. Der Verzicht auf diese hohlraumabschließenden Deckel bewirkt ebenfalls eine wesentliche Verbesserung der gesamten Wärmedämmung der Hohlblock-Wand.In the configuration according to the invention, the arrangement of such covers. or floors not required, since the wedge-shaped air layers - 9 - lying between isoleir plates - 8 - and webs -4 - at their thickest point - 9.1 - do not exceed that dimension - 12 - which still makes it impossible for bedding mortar to flow in. The omission of these cavity-closing covers also brings about a substantial improvement in the overall thermal insulation of the hollow block wall.

Es bezeichnet - 1 - die Richtung des Wärmeflusses durch die Hohlblockwand, - 3 - die Symmetrieebenen parallel zur Wandebene, zu welchen die Stege - 4 - spiegelbildlich-entgegengesetzten Verlauf aufweisen, - 4 - die etwa senkrecht zum Wärmefluß liegenden Stege. Die zwischen letzteren angeordneten Verbindungsstege sind mit - 5 - fUr einfach geknickten und - 6 - für mehrfach geknickten Verlauf bezeichnet.In the drawing, FIG. 1 shows the principle of the web grid on which the present invention is based.

Hier bezeichnet wiederum - 4 - die Stege etwa senkrecht zum Wörmefluß, die Stege etwa parallel zum Wärmefluß werden mit - 5 - für geknickten Verlauf und - 6 - für mehrfach geknickten Verlauf bezeichnet, zwischen denen die Isolierplatten - 8 - verlaufen. Der zwischen letzteren und den Stegen - 4 - entstehende Luftzwischenraum - 9 - besitzt jeweils eine dünnste Stelle - 9.2 - und eine dickste Stelle - 9.1 -. Das zu letzterer gehörige Dickenmaß ist mit - 12 - bezeichnet. Die den Mindestabstand - 9.2 - gewährleistenden Distanzrippen sind bei etwa rechteckigem Querschnitt mit - 10 - und bei etwa dreieckigem Querschnitt mit - 11 - bezeichnet.2 then shows a section of the web grid in the design according to the invention. Here again - 4 - denotes the webs approximately perpendicular to the flow of the Worm, the webs approximately parallel to the heat flow are designated with - 5 - for kinked course and - 6 - for multiple kinked course, between which the insulating plates - 8 - run. The air gap between the latter and the webs - 4 - 9 - each has a thinnest point - 9.2 - and a thickest point - 9.1 -. The thickness gauge belonging to the latter is designated with - 12 -. The spacing ribs guaranteeing the minimum distance - 9.2 - are designated by - 10 - for an approximately rectangular cross section and - 11 - in the case of an approximately triangular cross section.
