Abstract
Description
Die Erfindung bezieht sich auf einen Hochlochbaustein mit vertikal durchgehenden Durchbrechungen, die in Draufsicht in mehreren, nebeneinander verlaufenden Reihen angeordnet sind.The invention relates to a perforated brick with vertically continuous openings, which are arranged in a plan view in a plurality of rows running side by side.
Bei solchen Hochlochbausteinen wurde bisher meist danach getrachtet, den für die Wärmedämmung maßgebenden k-Wert zu verbessern, was durch die Vergrößerung des Anteiles der Durchbrechungsquerschnitte im Verhältnis zum Querschnitt des Bausteines erreicht wurde.In the case of such perforated building blocks, efforts have so far mostly been made to improve the k value which is decisive for thermal insulation, which was achieved by increasing the proportion of the perforation cross sections in relation to the cross section of the building block.
So liegt bei den bekannten derartigen Bausteinen das Verhältnis der Länge der Durchbrechungen zu dem gegenseitigen Abstand der einzelnen Reihen an Durchbrechungen oft über 10: 1. Dies führt zwar zu einer guten Wärmedämmung, jedoch auch zu einer Verminderung der Tragfähigkeit des Bausteines und insbesondere zu einer Verschlechterung der Schalldämmungseigenschaften.In the known building blocks of this type, the ratio of the length of the openings to the mutual spacing of the individual rows of openings is often more than 10: 1. Although this leads to good thermal insulation, it also leads to a reduction in the load-bearing capacity of the component and in particular to a deterioration the sound insulation properties.
So ist für die Berechnung der Schalldämmung das sogenannte Berger'sche Massengesetz maßgebend, nach welchem das Schalldämmaß Rw eine Funktion der flächenbezogenen Masse der Wände m′ in kg/m² ist. Dabei gilt die folgende Beziehung:
wobei für m′ die flächenbezogene Masse in kg/m² einzusetzen ist.For the calculation of sound insulation, the so-called Berger mass law is decisive, according to which the sound insulation value R w is a function of the area-related mass of the walls m 'in kg / m². The following relationship applies:
where for m ′ the mass per unit area in kg / m² is to be used.
Dabei hat sich weiters gezeigt, daß die theoretisch errechneten Werte des Schalldämmaßes Rw stark von der Geometrie der Hochlochkonfiguration des Bausteines abhängen, wobei sich geometriebedingte Abweichungen von bis zu 15 dB bei gleicher flächenbezogener Masse ergeben können.It has also been shown that the theoretically calculated values of the sound insulation value R w depend heavily on the geometry of the hole configuration of the module, which can result in geometry-related deviations of up to 15 dB with the same mass per unit area.
Ziel der Erfindung ist es daher, einen Hochlochbaustein der eingangs erwähnten Art vorzuschlagen, der sich bei hoher Tragfähigkeit und guter Wärmedämmung unabhängig von Bausteinmaterial durch ein hohes Maß an Schalldämmung auszeichnet.The aim of the invention is therefore to propose a perforated brick of the type mentioned at the outset which, with a high load-bearing capacity and good thermal insulation, is distinguished by a high degree of sound insulation regardless of the brick material.
Erfindungsgemäß wird dies dadurch erreicht, daß das Verhältnis der maximalen, in Richtung der Reihe gemessenen Durchbrechungslänge zum minimalen Abstand zweier benachbarter, zwei verschiedenen Reihen angehörender Durchbrechungen 1: 1 bis 6: 1 beträgt, und die Summe der minimalen, in Richtung der Reihe gemessenen Abstände der Durchbrechungen einer Reihe voneinander und vom Bausteinrand 12% bis 18% der sich in Richtung der Reihen erstreckenden Bausteinbreite beträgt.This is achieved according to the invention in that the ratio of the maximum opening length measured in the direction of the row to the minimum distance between two adjacent openings belonging to two different rows is 1: 1 to 6: 1, and the sum of the minimum distances of the openings of a row measured in the direction of the row from one another and from the block edge is 12% to 18% of the direction of the Rows extending block width is.
Es hat sich bei Versuchen gezeigt, daß die Einhaltung der obigen Verhältnisse einen sehr guten Kompromiß bezüglich der Wärmedämmung ergibt und dadurch ein Baustein geschaffen ist, der sich durch hervorragende Eigenschaften sowohl im Hinblick auf die Wärmedämmung als auch auf die Schalldämmung auszeichnet.It has been shown in tests that compliance with the above conditions results in a very good compromise with regard to thermal insulation, thereby creating a building block which is distinguished by excellent properties with regard to both thermal insulation and acoustic insulation.
Dabei hat sich gezeigt, daß für das Schalldämmaß im wesentlichen das Verhältnis der Längen der Durchbrüche zum Abstand der Durchbrüche zweier benachbarter Reihen und für die Wärmedämmung der Anteil der Stege zwischen den Durchbrüchen einer Reihe an der Gesamtbreite des Bausteines maßgebend ist.It has been shown that the ratio of the lengths of the openings to the spacing of the openings of two adjacent rows is essentially decisive for the sound insulation and the proportion of the webs between the openings of a row in the overall width of the module is decisive for the thermal insulation.
Genau in diesem speziellen Wertebereich für die geometrischen Parameter zeigte sich in Versuchen völlig überraschend ein hoher Wert der Schalldämmung, der außerhalb dieses Wertebereichs auf das bekannte, bisher erzielbare Schalldämmungsmaß zurückfiel.Exactly in this special range of values for the geometric parameters, experiments surprisingly showed a high sound insulation value, which fell outside of this value range to the known, previously achievable sound insulation index.
Beachtenswert ist dabei, daß durch die erfindungsgemäße Wahl der geometrischen Parameter die Wärmedämmungsfähigkeit und Tragfähigkeit des Bausteins keineswegs verringert wird.It is noteworthy that the thermal insulation capacity and load-bearing capacity of the building block are in no way reduced by the inventive choice of the geometric parameters.
Bevorzugt sollte das Verhältnis der maximalen, in Richtung der Reihe gemessenen Durchbrechungslänge zum minimalen Abstand zweier benachbarter, zwei verschiedenen Reihen angehörender Durchbrechungen 3: 1 bis 5: 1 gewählt werden und insbesondere sollte die Summe der minimalen, in Richtung der Reihe gemessenen Abstände der Durchbrechungen einer Reihe voneinander und vom Bausteinrand 13.5% bis 14.5% der sich in Richtung der Reihen erstreckenden Bausteinbreite betragen, da sich dadurch die optimalen Eigenschaften ergeben.The ratio of the maximum opening length measured in the direction of the row to the minimum distance between two adjacent openings belonging to two different rows should preferably be selected 3: 1 to 5: 1, and in particular the sum of the minimum distances of the openings measured in the direction of the row should be one Row from each other and from the block edge are 13.5% to 14.5% of the block width extending in the direction of the rows, since this results in the optimal properties.
In weiterer Ausgestaltung der Erfindung können die Durchbrechungen einen rechteckigen oder rautenförmigen Querschnitt mit vorzugsweise abgerundeten Ecken oder auch einen ovalen bzw. ellipsenförmigen Querschnitt aufweisen.In a further embodiment of the invention, the openings can have a rectangular or diamond-shaped cross section with preferably rounded corners or also an oval or elliptical cross section.
Ebenso ist es möglich, daß der Querschnitt einer Durchbrechung die Form eines flachen, gleichschenkeligen Dreiecks mit abgerundeten Ecken aufweist, dessen Basis in Längsrichtung der Reihen verläuft.It is also possible that the cross section of an opening has the shape of a flat, isosceles triangle with rounded corners, the base of which extends in the longitudinal direction of the rows.
Dabei können bevorzugt die in einer Reihe hintereinanderliegenden dreieckförmigen Durchbrechungen abwechselnd in entgegengesetzte Richtungen orientiert sein.The triangular perforations located one behind the other in a row can preferably be oriented alternately in opposite directions.
Mit all diesen Ausführungsformen ist die erwähnte Verbesserung der Schalldämmungseigenschaft erzielbar, ohne daß Abstriche hinsichtlich der Wärmedämmungseigenschaft oder der Tragfähigkeit gemacht werden müssen.With all of these embodiments, the aforementioned improvement in the sound insulation property can be achieved without having to make compromises in terms of the thermal insulation property or the load-bearing capacity.
Die Werte für die Wärmedämmung lassen sich noch weiter erhöhen, wenn gemäß einem weiteren Merkmal der Erfindung wenigstens eine der Reihen symmetrisch zur Bausteinlängsachse gekrümmt verläuft, oder auch wenn wenigstens eine der Reihen symmetrisch zur Bausteinlängsachse geneigt verläuft, wobei die die Bausteinlängsachse kreuzenden Durchbrechungen im Bereich der Bausteinlängsachse einen Knick aufweisen.The values for the thermal insulation can be increased even further if, according to a further feature of the invention, at least one of the rows is curved symmetrically to the longitudinal axis of the building block, or if at least one of the rows is symmetrical to the longitudinal axis of the building block, the openings crossing the longitudinal axis of the building block in the region of the Have a kink in the longitudinal axis of the block.
Dabei ergibt sich eine symmetrisch sehr tragfähige Anordnung, wenn die gekrümmt bzw. geneigt verlaufenden Reihen im Bereich der stirnseitigen Enden des Bausteines angeordnet sind und zu den im Bereich der gegenüberliegenden Stirnseite angeordneten Reihen entgegengesetzt gekrümmt bzw. geneigt verlaufen.This results in a symmetrically very stable arrangement if the curved or inclined rows are arranged in the region of the front ends of the component and are curved or inclined in the opposite direction to the rows arranged in the region of the opposite end side.
Bei allen diesen Ausführungsformen ist es möglich, daß die Durchbrechungen der jeweils nebeneinanderliegenden Reihen zueinander versetzt angeordnet sind, wobei die äußersten Durchbrechungen jeder zweiten Reihe die halbe Länge der übrigen Durchbrechungen aufweisen.In all of these embodiments, it is possible for the openings of the rows lying next to one another to be arranged offset with respect to one another, the outermost openings of every second row being half the length of the other openings.
Die erwähnten guten Ergebnisse lassen sich dabei mit Bausteinen aus Materialien wie Kalksandstein, Beton, Gasbeton, vorzugsweise gebranntem Ton erzielen.The good results mentioned can be achieved with building blocks made of materials such as sand-lime brick, concrete, gas concrete, preferably fired clay.

Die Summe aller in Reihenrichtung gemessenen Abstände X der Durchbrechungen voneinander und zum Bausteinrand beträgt ca. 13.6% der Bausteinbreite B.The ratio of the opening length L to the mutual minimum distance D between adjacent openings of two

Nur in diesen Bereichen ergibt sich der überraschende Anstieg der Schalldämmungsfähigkeit bei gleichbleibender Wärmedämmungsfähigkeit und Tragfähigkeit des Steines.It is only in these areas that there is a surprising increase in sound insulation capacity with the same thermal insulation capacity and load-bearing capacity of the stone.
