Abstract

The equipment comprise plates of hard plastics foam, and which are compressed elastically in the transverse direction and at right angles to the spars. Each bears via a lengthwise outer strip against one of the spars. They are thrust between the spars and into a common plane. Each plate (3,4) is placed obliquely via its strip (7) against its respective spar, the two plates including an angle of less than 180 degrees, with their inner lengthwise edges (8) bearing against each other. The tongue (9) on one fits inside the groove (10) in the other so as to form a hinge, and pressure is then applied to them at their inner edges so as to swing them into a common plane between the spars. They can be initially installed with their outer lengthwise strips protruding in front of the spars.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Zwischensparrendämmung, die zwischen zwei Sparren in einer gemeinsamen Ebene zwei Dämmplatten aufweist, die aus einem Kunststoffhartschaum bestehen, in einer zu den Sparren rechtwinkeligen Querrichtung elastisch zusammengedrückt sind und eine elastische Materialzusammendrückbarkeit in Querrichtung aufweisen, von denen jede mit einem äußeren Längsstirnstreifen an einem der beiden Sparren anliegt und die mit inneren Längsstirnstreifen gegeneinanderliegen, die mit Nut und Feder, die ineinandergreifen, versehen sind, bei dem die beiden Dämmplatten bei einander zugewendeten inneren Längsstirnstreifen über ihre der Querrichtung zugeordnete Breite zusammengedrückt werden und bei dem die beiden Dämmplatten in eine Stellung zwischen den beiden Sparren geschoben werden, bei der sie sich in einer gemeinsamen Ebene befinden.The invention relates to a method for producing an intermediate rafter insulation, which has two insulating boards between two rafters in a common plane, which consist of a plastic hard foam, are elastically compressed in a transverse direction perpendicular to the rafters and have an elastic material compressibility in the transverse direction, each with an outer longitudinal end strip abuts one of the two rafters and which lie opposite one another with inner longitudinal end strips which are provided with tongue and groove which interlock, in which the two insulating boards are pressed together with their inner longitudinal end strips facing each other over their width assigned to the transverse direction and in which the two insulation boards are pushed into a position between the two rafters in which they are in a common plane.

Die Erfindung betrifft auch Dämmplatten zur Durchführung des Verfahrens, die aus einem Kunststoffhartschaum bestehen, von zwei Längsstirnstreifen, von denen einer eine Nut oder eine Feder aufweist, begrenzt sind und quer zu den Längsstirnstreifen elastisch materialzusammendrückbar sind und bei denen sich die Feder und die Nut - im Querschnitt gesehen - zum freien Ende bzw. zum Grund hin verjüngen und die mit der Feder bzw. der Nut versehenen Längsstirnstreifen von zwei Flächenrandkanten begrenzt sind.The invention also relates to insulation boards for carrying out the method, which consist of a rigid plastic foam, are delimited by two longitudinal end strips, one of which has a groove or a tongue, and can be elastically compressed transversely to the longitudinal end strips and in which the tongue and the groove - seen in cross section - taper towards the free end or the bottom and the longitudinal end strips provided with the tongue or groove are delimited by two surface edges.

Es ist bekannt (EP-OS 0 019 058), die Nut und die Feder mittig und mit erheblichem Abstand von den beiden Flächenrandkanten anzuordnen und die Dämmplatte mit einer Vielzahl von Einschnitten zu versehen. Bei der Herstellung einer Zwischensparrendämmung werden die zwei Dämmplatten in einer gemeinsamen Ebene unter Ineinandergriff von Nut und Feder gegeneinandergelegt und dann durch Druck gegen die beiden äußeren Längsstirnstreifen derart über ihre Breite zusammengedrückt, daß sie zwischen die beiden Sparren geschoben werden können. Da das Zusammendrücken von Hand erfolgt und mit möglichst wenig Kraft erfolgen soll, sind die Einschnitte vorgesehen. Für das Zusammendrücken der Breite der beiden Dämmplatten muß mit der Hand an der äußeren Längsstirnseite der Druck ausgeübt werden, was als störend empfunden wird.It is known (EP-OS 0 019 058) to arrange the groove and the tongue centrally and at a considerable distance from the two surface edge edges and to provide the insulation board with a large number of cuts. When producing an intermediate rafter insulation, the two Insulation boards placed in a common plane with the tongue and groove interlocking and then pressed together over their width by pressure against the two outer longitudinal end strips in such a way that they can be pushed between the two rafters. Since the compression is done by hand and should be done with as little force as possible, the incisions are provided. To compress the width of the two insulation boards, pressure must be exerted by hand on the outer longitudinal face, which is perceived as annoying.

Eine Aufgabe der Erfindung ist es daher, ein Verfahren der eingangs genannten Art und dazu geeignete Dämmplatten der eingangs genannten Art zu schaffen, bei dem bzw. denen der Druck zum breitenmäßigen Zusammendrücken der Dämmplatten vereinfacht aufgebracht wird und das Einsetzen der Dämmplatten zwischen die Sparren vereinfacht ist.
Das erfindungsgemäße Verfahren ist, diese Aufgabe lösend, dadurch gekennzeichnet, daß jede Dämmplatte mit dem äußeren Längsstirnstreifen schräg an den zugeordneten Sparren gelegt wird und die beiden Dämmplatten einen Winkel < 180° miteinander bildend mit den inneren Längsstirnstreifen derart gegeneinandergelegt werden, daß die Nut und die Feder wie ein Gelenk aneinanderliegen, und daß die beiden Dämmplatten durch quer zu diesen gerichteten Druck nahe den inneren Längsstirnstreifen unter Drehung des Gelenks in die gemeinsame Ebene zwischen den Sparren gedrückt werden.
Die erfindungsgemäßen Dämmplatten sind zur Lösung der gestellten Aufgabe dadurch gekennzeichnet, daß die sich verjüngende Feder und die sich verjüngende Nut zu der einen Flächenrandkante hin verschoben derart angeordnet sind, daß sie bei Ineinandergriff unter gewinkelter Anordnung der Dämmplatten ein Gelenk bilden.An object of the invention is therefore to provide a method of the type mentioned and suitable insulation boards of the type mentioned, in which the pressure for compressing the insulation boards to a wide extent is simplified and the insertion of the insulation boards between the rafters is simplified .
The method according to the invention is to achieve this object, characterized in that each insulation board with the outer longitudinal end strips is placed obliquely on the associated rafters and the two insulation boards are formed at an angle <180 ° with the inner longitudinal end strips so that the groove and the The spring rests against each other like a joint, and that the two insulation boards are pressed into the common plane between the rafters by pressure directed transversely to them near the inner longitudinal end strips while rotating the joint.
The insulation panels according to the invention are characterized in order to achieve the object in that the tapering tongue and the tapering groove are arranged so that they are displaced towards one edge of the surface in such a way that they form a joint when the insulation panels are angled.

Gemäß der Erfindung erfolgt das breitenmäßige Zusammendrücken der beiden Dämmplatten durch einen Druck rechtwinklig zur Querrichtung, der vereinfacht von Hand aufgebracht werden kann. Dabei sind beide Dämmplatten mit den äußeren Längsstirnstreifen an den Sparren abgestützt. Es muß die Breite der beiden Dämmplatten nur um das Maß verringert werden, das nötig ist, um den in einer gemeinsamen Ebene befindlichen Dämmplatten die für den Halt zwischen den beiden Sparren erforderliche Spannkraft zu geben. Die für diese Montageweise erforderliche Abänderung der Dämmplatten ist relativ gering und hat zur Folge, daß dem Nut-Feder-Gebilde zusätzlich zu der Verriegelungsfunktion die Funktion eines Gelenks zugeordnet ist, bei dem sich die Feder unter flächiger Anlage in der Nut abwälzt.According to the invention, the two insulation boards are compressed in width by a pressure perpendicular to the transverse direction, which can be easily applied by hand. Both insulation boards are supported on the rafters with the outer longitudinal end strips. It is only necessary to reduce the width of the two insulation boards by the amount necessary to give the insulation boards located in a common plane the tension required for the hold between the two rafters. The modification of the insulation panels required for this mounting method is relatively small and has the consequence that the tongue and groove structure is assigned to the function of a joint in addition to the locking function, in which the tongue rolls under flat contact in the groove.

Besonders zweckmäßig und vorteilhaft ist es, wenn die Dämmplatten in der Stellung, in der sie sich in einer gemeinsamen Ebene zwischen den beiden Sparren befinden, zunächst nur mit einem Teil der Breite an den Dachsparren anliegen, und wenn die zueinander gewinkelten Dämmplatten mit den äußeren Längsstirnstreifen gegenüber den Sparren vorkragend an diese gelegt werden. In diesem Fall ist die Abstützung der Dämmplatten an den Sparren beim Einschwenken der beiden inneren Längsstirnstreifen verbessert. Die in eine gemeinsame Ebene gedrückten Dämmplatten werden anschließend ihrer Dicke nach vollständig zwischen die beiden Sparren geschoben.It is particularly expedient and advantageous if the insulation boards in the position in which they are located in a common plane between the two rafters initially only bear against the roof rafters with a part of the width, and if the insulation boards angled to one another with the outer longitudinal end strips cantilevered against the rafters. In this case, the support of the insulation boards on the rafters is improved when the two inner longitudinal end strips are swung in. The thickness of the insulation boards pressed into a common plane is then pushed completely between the two rafters.

Bei dem erfindungsgemäßen Verfahren ist also als besonders zweckmäßig und vorteilhaft vorgesehen, daß die Sparren einander vordere Sparrenkanten zuwenden und daß jede der beiden Dämmplatten mit dem äußeren Längsstirnstreifen an die zugeordnete vordere Sparrenkante angelegt wird und beim Drücken der Dämmplatten in die gemeinsame Ebene um die Sparrenkante wie um eine Achse gedreht wird. Diese Maßnahmen verdeutlichen die vereinfachte Montageweise.In the method according to the invention it is therefore particularly expedient and advantageous that the rafters face each other at the front rafters edges and that each of the two insulation boards with the outer longitudinal end strip is applied to the associated front rafters edge and when pressing the insulation boards into the common plane around the rafter edge as is rotated around an axis. These measures illustrate the simplified assembly method.

Die Erfindung umfaßt auch die nach dem erfindungsgemäßen Verfahren hergestellte und aus den erfindungsgemäßen Dämmplatten bestehende Zwischensparrendämmung. Nachfolgend wird die Erfindung anhand der Dämmplatten weiter beschrieben.The invention also includes the intermediate rafter insulation produced by the method according to the invention and consisting of the insulation panels according to the invention. The invention is further described below with the aid of the insulation boards.

Es ist möglich, dem Querschnitt der Nut und der Feder eine winkelige Gestalt zu geben; es besteht dann die Gefahr, daß beim Montieren Teile der Feder abbrechen. Es sind daher in der Regel die Nut und die Feder im Querschnitt gerundet. Es ist denkbar, die gerundete Feder und Nut sich über die gesamte Breite der inneren Längsstirnflächen erstrecken zu lassen. In der Regel sind aber Feder und Nut auf 5-50 % der Breite der Längsstirnflächen beschränkt, da dann die Drehbarkeit des Gelenks bzw. Scharniers beim Geradedrücken der Dämmplatten erleichtert ist.It is possible to give the cross section of the groove and the tongue an angular shape; there is then a risk that parts of the spring break off during assembly. The groove and tongue are therefore generally rounded in cross section. It is conceivable for the rounded tongue and groove to extend over the entire width of the inner longitudinal end faces. As a rule, however, the tongue and groove are limited to 5-50% of the width of the longitudinal end faces, since the rotatability of the joint or hinge is then made easier when the insulation boards are pushed straight.

Da die breitenmäßige Zusammendrückbarkeit der Dämmplatten bei der Erfindung vereinfacht ist, sind insofern Einschnitte nicht erforderlich. Besonders zweckmäßig und vorteilhaft ist es also, wenn die Dämmplatten über ihre Breite hin durchgehend voll, d.h. frei von Einschnitten ausgebildet sind. Die Dämmplatten sind also frei von Einschnitten und in der Breite nur durch Materialzusammendrückbarkeit zusammendrückbar. Die schlitzfreien Dämmplatten sind in sich steifer und neigen nicht zum Durchbiegen.Since the compressibility of the insulation boards in terms of width is simplified in the invention, incisions are therefore not necessary. It is particularly expedient and advantageous if the insulation boards are completely full over their width, i.e. are free of incisions. The insulation boards are therefore free of cuts and can only be compressed in width by compressing the material. The slot-free insulation boards are stiffer in themselves and do not tend to bend.

Die erfindungsgemäßen Dämmplatten sind in der Regel 40-240 mm dick. Sie sind in Querrichtung, d.h. in Breitenrichtung elastifiziert, d.h. elastisch zusammendrückbar, wobei der Kunststoff expandiert ist. Der expandierte Kunststoffhartschaum ist in der Regel aus Polystyrol und hat eine Rohdichte von 8 kg/m3 - 50 kg/m3. Besonders zweckmäßig und vorteilhaft ist es, wenn der Kunststoffhartschaum eine dynamische Steifigkeit s' von 3 MN/m3 - 250 MN/m3, insbesondere 10-80 MN/m3, aufweist. Bei dieser dynamischen Steifigkeit ist eine befriedigende elastische Zusammendrückbarkeit des Materials gegeben.The insulation boards according to the invention are generally 40-240 mm thick. They are elasticized in the transverse direction, ie in the width direction, ie elastically compressible, with the plastic being expanded. The expanded rigid plastic foam is usually made of polystyrene and has a bulk density of 8 kg / m 3 - 50 kg / m 3 . It is particularly expedient and advantageous if the rigid plastic foam has a dynamic stiffness s' of 3 MN / m 3 - 250 MN / m 3 , in particular 10-80 MN / m 3 . With this dynamic stiffness there is a satisfactory elastic compressibility of the material.

Jede Dämmplatte weist an beiden Querstirnstreifen in der Regel eine Vorsprung/Rücksprung-Gestaltung auf, mit der zwei am Querstirnstreifen aneinandergelegte Dämmplatten ineinandergreifen. Die Vorsprung/Rücksprung-Gestaltung ist z.B. eine Nut/Feder-Gestaltung oder eine Abstufung bzw. ein Stufenfalz. Jede Dämmplatte ist über ihre Dicke hin z.B. einstückig oder aus zwei oder mehr Schichten zusammengeklebt.Each insulation board generally has a projection / recess design on both transverse end strips, with which two insulating plates placed one against the other on the transverse end strips engage. The projection / recess design is, for example, a tongue and groove design or a gradation or a step fold. Each insulation board is, for example, in one piece across its thickness or glued together from two or more layers.

Gemäß Zeichnung umfaßt die Zwischensparrendämmung zwei Sparren 1, die aus Holz sind, länglich sind, im Querschnitt rechteckig sind, zueinander parallel sind, einander vordere Sparrenkanten 2 zuwenden und im wesentlichen plane bzw. unprofilierte Flächen bilden. Entlang den beiden Sparren 1 sind mehrere Folgen von je zwei Dämmplatten 3, 4 hintereinander angeordnet. Die Dämmplatten zweier benachbarter Folgen greifen jeweils mit einer Vorsprung/Rücksprung-Gestaltung 5 ineinander, die den Querstirnstreifen 6 der Dämmplatten 3, 4 zugeordnet ist. Die beiden Dämmplatten 3, 4 jeder Folge sind in Querrichtung, d.h. zwischen den beiden Sparren 1 in der Regel verschieden lang und auch von Folge zu Folge verschieden lang.According to the drawing, the intermediate rafter insulation comprises two rafters 1, which are made of wood, are elongated, are rectangular in cross section, are parallel to one another, turn towards each other, and form essentially flat or non-profiled surfaces. Along the two rafters 1, several sequences of two insulation boards 3, 4 are arranged one behind the other. The insulation panels of two adjacent sequences each interlock with a projection / recess configuration 5, which is assigned to the transverse end strips 6 of the insulation panels 3, 4. The two insulation boards 3, 4 of each sequence are in the transverse direction, i.e. between the two rafters 1 usually of different lengths and also of different lengths from sequence to sequence.

Jede Dämmplatte 3, 4 weist zwei in Richtung der Sparren 1 verlaufende Längsstirnstreifen 7, 8 auf, von denen jeweils der äußere, d.h. dem einen der Sparren 1 zugeordnete Längsstirnstreifen 7 eine plane bzw. unprofilierte Fläche ist und an einer der Flächen des Sparrens verschiebbar anliegt. Die Dicke der Dämmplatte 3, 4 ist geringer als die entsprechende Dicke bzw. Tiefe des Sparrens 1. Von den beiden einander zugewendeten inneren Längsstirnstreifen 8 ist der eine mit einer abgerundeten, simsartig vorspringenden Feder 9 und der andere mit einer abgerundeten zurückspringenden rinnenartigen Nut 10 versehen. Jede Dämmplatte 3, 4 weist zwei Seitenflächen 11 auf, von denen jede bei dem inneren Längsstirnstreifen 8 von einer Flächenrandkante 12 begrenzt ist. Die Nut 10 und die Feder 9 sind so weit zu der einen Seitenfläche 11 hin angeordnet, daß sie an der entsprechenden Flächenrandkante 12 beginnen.Each insulation board 3, 4 has two longitudinal end strips 7, 8 running in the direction of the rafters 1, each of which the outer, that is to say one of the rafters 1 assigned longitudinal end strips 7 is a flat or non-profiled surface and rests slidably on one of the surfaces of the rafters . The thickness of the insulation board 3, 4 is less than the corresponding thickness or depth of the rafter 1. Of the two mutually facing inner longitudinal end strips 8, one is provided with a rounded, ledge-like protruding spring 9 and the other with a rounded recessed groove-like groove 10 . Each insulation board 3, 4 has two side surfaces 11, each of which is delimited by a surface edge 12 in the inner longitudinal end strip 8. The groove 10 and the spring 9 are arranged so far towards the one side surface 11 that they start at the corresponding surface edge 12.

Durch Druck in Richtung eines Pfeils 13 gegen die entsprechenden Seitenflächen werden die beiden Dämmplatten 3, 4 aus der gewinkelten Stellung in eine gemeinsame Ebene zwischen den beiden Sparren 1 gebracht. Gemäß Fig. 3 werden die Dämmplatten 3, 4 aus Lieferdämmplatten 14 gewonnen, die jeweils an einer Längsseite mit der Feder 9 und an der anderen Längsseite mit der Nut 10 versehen sind und entlang einer gestrichelt angedeuteten Trennebene 15 zerschnitten werden.Fig. 2 shows the two insulation boards 3, 4 during assembly in the angled arrangement, in which they are each supported with the outer longitudinal end strip 7 on the front rafter edge 2 and the groove 10 and the spring 9 interlock like a joint. By pressing in the direction of an arrow 13 against the corresponding side surfaces, the two insulation boards 3, 4 are brought out of the angled position into a common plane between the two rafters 1. According to FIG. 3, the insulation boards 3, 4 are obtained from delivery insulation boards 14, which are each provided with the tongue 9 on one long side and with the groove 10 on the other long side and are cut along a dividing plane 15 indicated by dashed lines.
