Description
B e s c h r e i b u n g d e r E r f i n d un g Hohlblockstein m i t i s o 1 i e r e n d e r Z w i s c h e n s c h i c h t Die Erfindung betrifft einen Hohlbockstein mit wandparallel verlaufender, von einer Stirnfläche zur anderen und von einer Lagerfläche zur anderen durchgehenden Zwischenschicht aus wärme- und/oder schalldämmendem Material, die mit entsprechenden Zwischenschichten von anschließenden, im Verband versetzten gleichartigen Steinen eine geschlossene, die gesamte Wandfläche durchziehende Isolierschicht bilden.D e s c h r e i n g th e r E r f i n d un g Hollow block m i t i s o 1 i e r e n d e r Z W i s c h e n s c h i c h t The invention relates to a Hollow block with parallel to the wall, from one face to the other and from one storage surface to the other continuous intermediate layer from heat and / or sound-absorbing material, which with appropriate intermediate layers of subsequent, in a bond, stones of the same type offset a closed, entire wall surface Form a continuous insulating layer.
Derartige STeine haben den Zweck, eine lükkenlose Isolierung gegen Wärmeverluste und/oder Schall über die gesamte aus ihnen errichtete Wand zu bewirken und die Schall- und Wärmedämmung des damit errichteten Mauerwerkes gegenüber herkömmlichen Bauweisen erheblich zu verbessern.Such stones have the purpose of a gapless insulation against To cause heat loss and / or sound over the entire wall built from them and the sound and heat insulation of the masonry built with it compared to conventional ones Significantly improve construction methods.
Bekannt ist, in einem Hohlblockstein eine wandparallele Isolierschicht aus dem Material anzuordnen, wobei die beiden durch die Isolierschicht getrennten Steinteile monolithisch durch die die Isolierschicht durchsetzenden Stege verbunden sind und wobei ferner diese Stege gegenüber den die parallel zur Isolierschicht verlaufenden Luftkammerreihen abteilenden Querstegen versetzt angeordnet sind, um den über die die Isolierschicht durchdringenden Verbindungsstege führenden Wärmeleitweg möglichst lang zu gestalten. (DBP 1.708.765) Es hat sich gezeigt, daß eine lückenlose Verbindung der Isolierschicht zweier benachbarter derartiger Steine im Verband an den Stirnfugen dann nicht eintritt, wenn einer der Steine oder beide nicht völlig horizontal auf ihrem Mörtelbett aufliegen. Die Stirnfuge ist dann nicht im Lot, so daß keilförmige Spalträume zwischen den Stirnflächen der Isolierschicht entstehen können. Dieser aus einem nicht immer zu vermeidenden ungleichen Mörtelauftrag herrührende Nachteil hat zur Folge, daß entweder in diesen Spaltraum Mörtel eintritt, der eine relativ gute Wärmebrücke bildet, oder daß von Wand zu Wand durchgehende Hohlräume verbleiben. In diesen können wärmetransportierende Konvektionen stattfinden oder auch beide Wandseiten verbindende Luftströmungen entstehen. Dies würde die Gesamtisolierwirkung einer aus den genannten Steinen gebildeten Wand erheblich beeinträchtigen.It is known to have an insulating layer parallel to the wall in a hollow block from the material, with the two separated by the insulating layer Stone parts are monolithically connected by the webs penetrating the insulating layer and furthermore, these webs are opposite to those parallel to the insulating layer extending rows of air chambers dividing transverse webs are arranged offset to the heat conduction path leading through the connecting webs penetrating the insulating layer to make it as long as possible. (DBP 1,708,765) It has been shown that a complete Connection of the insulating layer of two adjacent stones of this type in association the front joints will not enter if one or both of the stones is not completely lie horizontally on their mortar bed. The front joint is then not plumb, so that wedge-shaped gaps arise between the end faces of the insulating layer can. This stems from an uneven application of mortar, which cannot always be avoided The disadvantage has the consequence that either mortar occurs in this gap, the one forms a relatively good thermal bridge, or that from wall to wall continuous Cavities remain. Heat-transporting convections can take place in these or air currents connecting both sides of the wall arise. This would be the Significantly impair the overall insulating effect of a wall formed from the stones mentioned.
Durch ungleichmäßigen Mörtelauftrag können solche Fugenundichtigkeiten mit gleichen unerwünschten Wirkungen auch an den Lagerfugen entstehen.Uneven mortar application can cause such joint leaks with the same undesirable effects also occur at the bed joints.
Aufgabe der Erfindung ist es, auch bei ungenau versetzten Steinen einen sicheren Fugenschluß der Isolierschicht zu gewährleisten, so daß die Isolierschichten im Verband mit gleichartigen Steinen geschlossene Fugen aufweisen, um tatsächlich eine sich über die ganze Wand erstreckende Isolierfläche zu erhalten.The object of the invention is, even with imprecisely offset stones to ensure a secure joint connection of the insulating layer, so that the insulating layers in association with stones of the same type have closed joints in order to actually to obtain an insulating surface that extends over the entire wall.
Diese Aufgabe der Erfindung wird bei der im Oberbegriff des Anspruches 1 angegebenen Hohlblocksteinausgestaltung durch die in den Ansprüchen gekennzeichneten Ausbildungen gelöst.This object of the invention is achieved in the preamble of the claim 1 specified hollow block design by the characterized in the claims Training solved.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen Fig. 1 einen Horizontalschnitt durch einen erfindungsgemäßen Hohlblockstein in Ebene I - I in Fig. 2 Fig. 2 zwei gleichartige, aufeinander aufruhende erfindungsgemäße Hohlblocksteine in durchgehendem Vertikalschnitt, wobei der obere Stein in Ebene II - II in Fig. 1 und der untere Stein in Ebene IIa - IIa in Fig. 1 geschnitten ist Fig. 3 eine schematische perspektivische Darstellung der Anordnung der Isolierschicht eines erfindungsgemäßen Hohlblocksteines.An embodiment of the invention is shown in the drawing and is described in more detail below. 1 shows a horizontal section by a hollow block according to the invention in plane I - I in Fig. 2 Fig. 2 two similar hollow blocks according to the invention resting on one another in a continuous Vertical section, with the upper stone in level II - II in Fig. 1 and the lower stone in plane IIa-IIa in Fig. 1, Fig. 3 is a cut schematic perspective illustration of the arrangement of the insulating layer of a hollow block according to the invention.
Der Hohlblockstein (1) besteht aus zwei wandparallelen Steinhälften (2 und 3), die je eine Reihe wandparalleler Luftkammern (4 und 5) aufweisen. Zwischen den Steinhälften (2, 3) ist eine Isolierkammer (6) angeordnet, die von Lagerfläche zu Lagerfläche und von Stirnfläche zu Stirnfläche durchgeht. Beide Steinhälften (2, 3) sind durch Stege (7 und 8) monolithisch verbunden, die die Isolierkammer (6) durchsetzen. Die Isolierkammer (6) ist mit einer Isolierschicht (9) aus verschäumtem Kunststoff, z.B. Polysterol oder Polyurethan, gefüllt.The hollow block (1) consists of two wall-parallel stone halves (2 and 3), each of which has a row of air chambers (4 and 5) parallel to the wall. Between the stone halves (2, 3) an insulating chamber (6) is arranged, the storage area goes through to the bearing surface and from face to face. Both stone halves (2, 3) are monolithically connected by webs (7 and 8) that form the insulating chamber (6) enforce. The insulating chamber (6) has an insulating layer (9) made of foamed Plastic, e.g. polystyrene or polyurethane, filled.
Die Steinhälfte (2) weist an ihren Stirnseiten wandparallele Ausnehmungen (10 und 11) auf, die beim stirnseitigen Zusammensetzen gleicharrtiger erfindungsgemäßer Steine Mörteltaschen bilden. Die Steinhälfte (3) weist auf der einen Stirnseite einen wandparallelen Vorsprung (12) und auf der anderen Stirnseite eine entsprechende Nut (13) zur Verzahnung stirnseitig aneinander stoßender gleichartiger erfindungsgemäßter Steine auf.The stone half (2) has recesses parallel to the wall on its end faces (10 and 11), the same arrtiger inventive when assembling the end face Stones form pockets of mortar. The stone half (3) has one end face a projection (12) parallel to the wall and a corresponding one on the other end face Groove (13) for the toothing of the same type according to the invention butting one another on the end face Stones up.
Die Isolierschicht (9) ist auf der einen Stirnseite mit einer im horizontalen Querschnitt dreieckigen, sich über die ganze Breite der Isolierschicht rillenförmig über deren ganze stirnseitige Höhe erstreckenden Ausnehmung (14) versehen. Ihr entspricht ein sich über deren ganze stirnseitige Höhe erstreckender Vorsprung (15) der Isolierschicht (9) mit ebenfalls dreieckigem horizontalem Querschnitt.The insulating layer (9) is on one end face with a horizontal one Triangular cross-section, extending over the full width of the Insulating layer Provided groove-shaped over the entire frontal height extending recess (14). It corresponds to a projection extending over its entire frontal height (15) the insulating layer (9) also with a triangular horizontal cross-section.
Beim stirnseitigen Zusammensetzen erfindungsgemäßer gleichartiger Steine greifen die Ausnehmung (14) und der Vorsprung (15) über die ganze Steinhöhe nut- und federartig ineinander.When assembling on the face side according to the invention similar Stones grip the recess (14) and the projection (15) over the entire height of the stone like a tongue and groove into each other.
Es ist zweckmäßig, daß die den Vorsprung (15) aufweisende Seite der Isolierschicht (9) einen kleinen Abstand über die Stirnseite (16) des Hohlblocksteines (1) vorspringt, der so groß bemessen ist, wie sich das Material der Isolierschicht (9) beim stirnseitigen Zusammensetzen der Hohlblocksteine zusammendrücken läßt. Im Fall des keilförmigen Klaffen der Stoßfuge kann das nicht zusammengedrückte Material der Isolierschicht den Spalt überbrücken und versperren.It is useful that the projection (15) having the side of the Insulating layer (9) a small distance over the end face (16) of the hollow block (1) protrudes, which is as large as the material of the insulating layer (9) can be pressed together when the frontal assembly of the hollow blocks. In the case of the wedge-shaped gaping of the butt joint, the uncompressed material can the insulating layer bridge and block the gap.
Es ist ferner zweckmäßig, daß der Winkel der Ausnehmung-(14) spitzer ist als der des Vorsprunges (15).It is also useful that the angle of the recess (14) is more acute is than that of the projection (15).
Lagerfugenseitig ist die Isolierschicht (9) entsprechend ausgestaltet. Auf der oberen Lagerseite ist eine sich über die ganze Steinlänge erstreckende Nut mit gleichem Querschnitt wie die stirnseitige Nut (14) vorgesehen, die diese in Umfangsrichtung fortsetzt. Auf der unteren Lagerfläche ist in entsprechender Weise ein Vorsprung (18) angeordnet, der den gleichen dreieckigen Querschnitt aufweist wie der stirnseitige Vorsprung (15), den er in Umfangsrichtung fortsetzt. An den Ecken der Isolierschicht (9) bilden sich Verschneidungen der Nute (14, 17) mit den Vorsprüngen (15, 18), wie dies in Fig. 3 bei (19, 20, 21) dargestellt ist.On the bearing joint side, the insulating layer (9) is designed accordingly. On the upper side of the bearing there is a groove that extends over the entire length of the stone provided with the same cross-section as the end-face groove (14), which this in Circumferential direction continues. On the lower bearing surface is in a corresponding manner a projection (18) arranged which has the same triangular cross-section like the frontal one Projection (15) he in the circumferential direction continues. Intersections of the grooves form at the corners of the insulating layer (9) (14, 17) with the projections (15, 18), as shown in Fig. 3 at (19, 20, 21) is.
An den beiderseitigen wandseitigen Kanten der oberen Lagerfläche (22) sind wandparallele, über die ganze Stein länge verlaufende eingeschnittene Ausnehmungen (23 und 24) vorgesehen, an der unteren Lagerfläche (25) dagegen entsprechende, ebenfalls über die ganze Steinwandlänge verlaufende,parallele,in die Ausnehmungen (23, 24) entsprechender Steine passende Vorsprünge (26, 27). Diese Vorsprünge (26, 27) sind etwa doppelt so hoch wie die Ausnehmungen (23, 24), um Platz für den Lagerfugenmörtel (28) zu lassen, wie die Fig. 2 zeigt. Die Isolierschicht (9) steht an der unteren Lagerfläche (25) um die Höhe des für den Lagerfugenmörtel (28) vorgesehenen Raumes sowie um einen weiteren Betrag über, um den sie beim Versetzen der Steine zusammengepreßt werden kann.On both sides of the wall-side edges of the upper bearing surface (22) are wall-parallel, cut recesses running over the entire length of the stone (23 and 24) provided, on the other hand, on the lower bearing surface (25), likewise running parallel over the entire length of the stone wall into the recesses (23, 24) corresponding stones matching projections (26, 27). These projections (26, 27) are about twice as high as the recesses (23, 24) to make room for the bedding mortar (28), as shown in FIG. 2. The insulating layer (9) is on the lower one Storage area (25) by the height of the space provided for the storage joint mortar (28) and by a further amount by which they are compressed when moving the stones can be.
Auf diese Weise wird verhindert, daß der Fugenmörtel (28), der mit einer Schablone genau auf die für ihn vorgesehenen Flächen aufgetragen werden kann, in die Lagerfugen von Isolierschichten (9) eindringen kann.In this way it is prevented that the grout (28) with a stencil can be applied exactly to the areas intended for it, can penetrate into the bed joints of insulating layers (9).
Durch die erfindungsgemäße Anordnung der Nuten und Vorsprünge der Isolierschicht (9) und das Überstehen der Isolierschicht an ihren die Vorsprünge tragenden Seiten über die Steinflächen wird erreicht, daß bei nicht völlig gleichmäßigem Mörtelauftrag oder nicht ausreichend lotrechtem Versetzen der Steine die Verzahnung der Isolierschicht (9) und ihre beschriebene Deformierbarkeit entstehende Spalten verschließen können.The inventive arrangement of the grooves and projections Insulating layer (9) and the protrusion of the insulating layer on their projections load-bearing sides over the stone surfaces is achieved that when not completely even mortar application or insufficient vertical displacement of the Stones, the interlocking of the insulating layer (9) and its deformability as described can close resulting gaps.
