Description

Die Erfindung betrifft eine Fachwerkkonstruktion insbesondere aus Holz, welche eine oder mehrere durch jeweils gegenüberliegende Begrenzungselemente sowie durch zwei gegenüberliegende Beplankungselemente umgrenzte Kammern aufweist.The invention relates to a truss structure, in particular made of wood, which has one or more bounded by respective opposing boundary elements and by two opposite Planking elements chambers.

Derartige Fachwerkkonstruktionen werden zum Bau selbsttragender Wände oder von vor vorhandene Wände, insbesondere Außenwände vorgehängten Konstruktionen verwendet. In die vorhandenen Kammern dieser Konstruktionen wird Isoliermaterial eingebracht, indem entweder an die Form der Kammern angepasste Isolierelemente eingesetzt werden oder aber es wird loses Isoliermaterial aus natürlichen oder künstlichen Rohstoffen oder Rohstoffgemischen eingeblasen. Beim Einbringen der Isoliermaterialien soll erreicht werden, dass alle Kammern möglichst vollständig und gleichmäßig mit dem Isoliermaterial ausgefüllt sind, um Kältebrücken in der Fachwerkkonstruktion zu vermeiden.Such truss structures are used for the construction of self-supporting walls or pre-existing walls, in particular exterior walls suspended structures. In the existing chambers of these constructions insulating material is introduced by either the insulating chambers adapted to the shape of the chambers are used or it is blown loose insulating material from natural or man-made raw materials or mixtures of raw materials. When introducing the insulating materials should be achieved that all chambers are filled as completely and uniformly with the insulating material to avoid cold spots in the truss structure.

Werden größere Isolierelemente manuell an die Hohlräume angepasst und eingepasst, entstehen meist Lücken zwischen den Begrenzungselementen der Kammern und den Isolierelementen. Außerdem ist der Arbeitsaufwand vergleichsweise hoch. Beim Einblasen von losem Isoliermaterial wird bisher an einer oder mehreren Stellen der Fachwerkkonstruktion durch Löcher in der Beplankung ein Schlauch oder dergleichen Zuführung für das Isoliermaterial in eine Kammer der Fachwerkkonstruktion eingeführt und unter Druck das Isoliermaterial eingeblasen. Stehen die Kammern der Fachwerkkonstruktion miteinander in Verbindung, kann das Isoliermaterial entweder alle Kammern und dabei unter Umständen auch in Bereiche, wo keine Isolierung erwünscht ist, gelangen, oder aber es wird keine gleichmäßige und vollständige Befüllung aller Kammern, insbesondere bei komplizierten oder unregelmäßigen Konstruktionen, erreicht.If larger insulating elements are manually adapted and fitted to the cavities, gaps usually arise between the boundary elements of the chambers and the insulating elements. In addition, the Workload comparatively high. When blowing loose insulating material hitherto at one or more points of the truss structure through holes in the planking a tube or the like feed for the insulating material is introduced into a chamber of the truss structure and injected under pressure, the insulating material. If the chambers of the truss structure communicate with each other, the insulating material may either enter all the chambers and possibly also in areas where no insulation is desired, or else there will be no uniform and complete filling of all the chambers, especially in complicated or irregular constructions. reached.

Sind die einzelnen Kammern geschlossen ausgebildet, muss zwar jede Kammer einzeln befüllt werden, eine gleichmäßige und vollständige Befüllung der Kammer ist dadurch aber einfacher zu erreichen. Dabei besteht jedoch wiederum das Problem, dass die mit dem losen Isoliermaterial eingeblasene Luft und die in der Kammer durch das Isoliermaterial zu verdrängende Luft nur unzureichend aus der Kammer entweichen kann, sodass neben der Zuführung eine entsprechende Entlüftung nötig ist. Für die Zuführung und Entlüftung ist eine entsprechend große Öffnung für einen Zuführschlauch mit einem Rückschlauch für die Luft oder zwei separate Öffnungen zu jeder Kammer in der Beplankung nötig, welche nachträglich wieder verschlossen werden muss/müssen.If the individual chambers are formed closed, each chamber must be filled individually, but a uniform and complete filling of the chamber is thereby easier to achieve. However, there is again the problem that the injected with the loose insulating material air and in the chamber to be displaced by the insulating air can only insufficiently escape from the chamber, so that in addition to the feed a corresponding venting is necessary. For the supply and venting a correspondingly large opening for a supply hose with a return hose for the air or two separate openings to each chamber in the planking is necessary, which must be closed again later.

Aus der US 6 481 172 B1 ist bereits eine Wandkonstruktion bekannt, die äußere Beplankungselemente und dazwischen einen Isolierkern aufweist. An den Wand-Innenseiten der Beplankungselemente sind zueinander seitlich in Wandrichtung beabstandete Stützen vorgesehen, die paarweise und einseitig jeweils nur mit einer der Beplankungselemente verbunden sind, so dass jeweils ein Durchtritt zwischen gegenüber liegenden Stützen gebildet ist. Da sich das Isoliermaterial des Isolierkerns somit durchgehend über die gesamte Wandfläche erstreckt, sind keine gegeneinander abgegrenzten Kammern gebildet und keine Maßnahmen zur vollständigen und gleichmäßigen Befüllung mit einblasbarem Isoliermaterial vorgesehen.From the US Pat. No. 6,481,172 B1 already a wall construction is known, the outer paneling elements and having an insulating core between them. On the wall insides of the Beplankungselemente mutually laterally spaced in the wall direction supports are provided, which are connected in pairs and on one side only with one of the planking elements, so that in each case a passage between opposite Columns is formed. Since the insulating material of the insulating core thus extends continuously over the entire wall surface, no mutually delimited chambers are formed and provided no measures for complete and uniform filling with einblasbarem insulating material.

Aus der US 2004/140038 A1 ist eine Innenwand mit einem Trägergerüst bekannt, das zwischen einer Innenwand und einer Außenwand als Beplankungselemente angeordnete Ständer aufweist. Dabei wird in einem zusätzlichen Arbeitsgang eine unbeplankte Flachseite der Innenwand zunächst mit einem Netz als filterartiges Rückhalteelement abgedeckt, um in den Bereich zwischen benachbarten Ständern eingeblasenes Isoliermaterial zurückzuhalten. Anschließend wird dann auf die Flachseite mit dem Netz noch eine Innenwand als Beplankungselement aufgebracht. Die Ständer sind als massivem Vierkantmaterial und verbinden direkt die beiden äußeren Beplankungselemente, so dass dadurch unerwünschte Wärmebrücken gebildet sind.From the US 2004/140038 A1 an inner wall with a support frame is known, which has arranged between an inner wall and an outer wall as Beplankungselemente stand. In this case, an unplastered flat side of the inner wall is initially covered with a net as a filter-like retention element in an additional operation to retain in the area between adjacent uprights injected insulating material. Subsequently, an inner wall is then applied as a planking element on the flat side with the network. The stands are as solid square material and connect directly the two outer planking elements, so that undesirable thermal bridges are formed.

Es besteht daher die Aufgabe, eine Fachwerkkonstruktion zu schaffen, bei der ein gleichmäßiges und vollständiges Befüllen aller Kammern mit insbesondere losem Isoliermaterial mittels Einblasen einfach und schnell möglich ist.It is therefore an object to provide a truss structure in which a uniform and complete filling of all chambers with particular loose insulating material by blowing is easy and fast.

Zur Lösung dieser Aufgabe schlägt die Erfindung vor, dass die Begrenzungselemente als tragende Leiterelemente ausgebildet sind und jeweils Längs- und Querstreben aufweisen, dass zumindest eines der Begrenzungselemente zwischen benachbarten Kammern luftdurchlässige Bereiche mit einem filterartigen Rückhalteelement aufweist, dass das filterartige Rückhalteelement zwischen den einen Freiraum des Begrenzungselements umgrenzenden Längs- und Querstreben angeordnet ist und dass das filterartige Rückhalteelement diesen Freiraum vollständig überdeckt.To solve this problem, the invention proposes that the limiting elements are designed as load-bearing conductor elements and each have longitudinal and transverse struts that at least one of the boundary elements between adjacent chambers air-permeable areas having a filter-like retaining element, that the filter-like retaining element between the free space of the Limiting element bounding longitudinal and transverse struts is arranged and that the filter-like retaining element completely covers this space.

Wird in eine Kammer Isoliermaterial eingeblasen, kann durch das filterartige Rückhalteelement die Transportluft entweichen. Eine Luftrückführung durch einen Rückschlauch oder eine zusätzliche Öffnung in den Beplankungselementen sind nicht erforderlich. Dadurch ist außerdem ein gleichmäßiges und vollständiges Befüllen der einzelnen Kammern der Fachwerkkonstruktion möglich, was weiter begünstigt wird, wenn nicht nur eines der Begrenzungselemente, sondern mehrere oder alle Begrenzungselemente einer Kammer luftdurchlässige Bereiche aufweisen. Insbesondere schwer auffindbare Kälte- beziehungsweise Wärmebrücken innerhalb der Fachwerkkonstruktion können so vermieden werden.If insulating material is blown into a chamber, the transport air can escape through the filter-like retaining element. An air return through a return hose or an additional opening in the planking elements are not required. As a result, a uniform and complete filling of the individual chambers of the truss structure is also possible, which is further favored if not only one of the boundary elements, but several or all boundary elements of a chamber have air-permeable areas. In particular, hard to find cold or thermal bridges within the framework construction can be avoided.

Durch das filterartige Rückhalteelement kann die Luft auf einer im Vergleich zu den bisherigen kleinen Entlüftungsöffnungen vergleichsweise großen Fläche schnell und gleichmäßig entweichen, wodurch auch ein schnelles, gleichmäßiges und vollständiges Befüllen mit Isoliermaterial möglich ist. Ein Aufstauen von Luft wird vermieden.Through the filter-like retaining element, the air can escape quickly and evenly on a comparatively large area compared to the previous small vents, whereby a fast, uniform and complete filling with insulating material is possible. Damming up of air is avoided.

Durch die Ausbildung der Begrenzungselemente als tragende Leiterelemente mit Längs- und Querstreben lassen sich selbstragende Fachwerkkonstruktionen aufbauen. Die quer zur Wandebene verlaufenden, sprossenartigen Querstreben stabilisieren die Längsstreben und halten diese auf Abstand. Für diese Querstreben genügen vergleichsweise kleine Querschnitte und auch durch die zueinander beabstandete Anordnung sind weder durch diese Querstreben noch durch die dazwischen befindlichen, filterartigen Rückhalteelemente merkbare Wärmebrücken gebildet. Das als tragendes Leiterelement ausgebildete Begrenzungselement ist damit wärmebrückenminimiert und trägt ebenso wie die vollständige und gleichmäßige Befüllung der Kammern mit Isoliermaterial dazu bei, Kälte- beziehungsweise Wärmebrücken in der Fachwerkkonstruktion zu vermeiden.
Das filterartige Rückhalteelement ist dabei zum Zurückhalten von Partikeln wie Flocken, Fasern, Körner, Streu, Pellets oder dergleichen Partikel aus wärmeisolierendem Material innerhalb einer Kammer ausgebildet.
Einblasbares Isoliermaterial besteht in den meisten Fällen aus derartigen Partikeln, die meist einen Durchmesser von etwa fünf Millimeter oder größer aufweisen.By forming the boundary elements as load-bearing ladder elements with longitudinal and transverse struts self-supporting truss structures can be built. The transversely to the wall plane extending, rung-like crossbars stabilize the longitudinal struts and keep them at a distance. For these cross braces are sufficient comparatively small cross sections and also by the spaced-apart arrangement are formed neither by these cross braces nor by the intervening, filter-like retaining elements noticeable thermal bridges. The designed as a supporting conductor element limiting element is thus minimized thermal bridges and contributes as well as the complete and uniform filling of the chambers with insulating material This helps to avoid cold or thermal bridges in the truss structure.
The filter-like retaining element is designed for retaining particles such as flakes, fibers, grains, litter, pellets or the like particles of heat-insulating material within a chamber.
Inflatable insulating material consists in most cases of such particles, which usually have a diameter of about five millimeters or larger.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, dass das filterartige Rückhalteelement durch ein Polyestervlies gebildet ist. Derartige Polyesterfliese sind vergleichsweise feinmaschig und können so auch kleine Partikel zuverlässig zurückhalten. Dennoch sind sie auch gut luftdurchlässig und kostengünstig.A preferred embodiment of the invention provides that the filter-like retaining element is formed by a polyester fleece. Such polyester tile are relatively fine mesh and can thus reliably hold even small particles. Nevertheless, they are also good air permeable and inexpensive.

Eine alternative Ausführungsform sieht vor, dass das filterartige Rückhalteelement als feinmaschiges Netz ausgebildet oder aus Gaze gebildet ist. Insbesondere beim Einsatz von Isolierflocken mit mittlerem oder größerem Volumen kann ein derartiges Netz vorteilhaft sein, weil Luft durch die Maschen des Netzes praktisch ungehindert hindurchtreten kann. Netze oder Gaze sind ebenso wie Polyestervlies kostengünstig.An alternative embodiment provides that the filter-like retaining element is formed as a fine mesh or formed from gauze. In particular, when using Isolierflocken medium or larger volume, such a network may be advantageous because air can pass through the mesh of the network practically unhindered. Nets or gauze are inexpensive as well as polyester fleece.

Für eine einfache Montage der filterartigen Rückhalteelemente innerhalb der Fachwerkkonstruktion ist es vorteilhaft, wenn die Begrenzungselemente aus Schichtholz bestehen und wenn das filterartige Rückhalteelement zwischen zwei benachbarten, miteinander verleimten Brettschichten der Begrenzungselemente befestigt, insbesondere verleimt ist.
Dadurch sind keine weiteren Befestigungselemente zur Halterung der filterartigen Rückhalteelemente nötig. Die filterartigen Rückhalteelemente können während der Herstellung der Begrenzungselemente aus einzelnen Brettschichten auf einfache Weise als eine Lage zwischen zwei Brettschichten eingelegt werden und zusammen mit diesen verklebt oder verleimt werden. Insbesondere bei einer industriellen Herstellung der Begrenzungselemente auf Taktstraßen oder dergleichen automatisierten Anlagen ist .... diese Befestigungsmethode kostengünstig und schnell. Durch eine derartige Verleimung kann auf einfache Weise eine gute Dichtigkeit zwischen den Längs- und Querstreben und dem filterartigen Rückhalteelement erreicht werden.For a simple mounting of the filter-like retaining elements within the framework construction, it is advantageous if the boundary elements consist of laminated wood and if the filter-like retaining element between two adjacent, glued laminated boards of the boundary elements attached, in particular glued.
As a result, no further fastening elements for holding the filter-like retaining elements are necessary. The filter-like retaining elements can be inserted during the production of the boundary elements of individual board layers in a simple manner as a layer between two board layers and glued or glued together with these. In particular, in an industrial production of the boundary elements on tact lines or the like automated systems .... This method of attachment cost-effective and fast. By such a gluing a good seal between the longitudinal and transverse struts and the filter-like retaining element can be achieved in a simple manner.

Hereinafter, an embodiment of the invention with reference to the drawings will be described in more detail. It shows in partly schematized representation:

Fig. 2
a perspective view of a limiting element according to the invention with a filter-like retaining element in a space bounded by longitudinal and transverse struts free space.

Eine im Ganzen mit 1 bezeichnete Fachwerkkonstruktion aus Holz ist in Fig.1 dargestellt und weist mehrere durch jeweils zwei oben und unten sowie rechts und links gegenüberliegende Begrenzungselemente 2, 12 sowie durch gegenüberliegende Beplankungselemente 3 umgrenzte Kammern 4 auf, wobei die eine Beplankung 3 durch eine Wand 11 gebildet ist. In Fig.1 und deutlicher in Fig.2 ist erkennbar, dass die senkrecht verlaufenden Begrenzungselemente 2 luftdurchlässige Bereiche mit einem filterartigen Rückhalteelement 5 aufweisen. Die waagerecht verlaufenden Begrenzungselemente 12 sind durch geschlossene Bretter gebildet. Die Luft kann aus einer Kammer 4 durch die filterartigen Rückhalteelemente 5 jeweils in die links und/oder rechts benachbarte Kammer 4 während des Einblasens von Isoliermaterial abströmen, was für eine gleichmäßige und vollständige Füllung einer Kammer 4 mit Isoliermaterial sorgt. Die Öffnungen zur Zuführung des Isoliermaterials in die Kammern 4 sind in Fig.1 nicht näher dargestellt.A truss structure made of wood, generally designated 1, is in Fig.1 shown and has a plurality of each by two top and bottom and right and left opposite boundary elements 2, 12 and by opposing planking 3 bounded chambers 4, wherein a planking 3 is formed by a wall 11. In Fig.1 and more clearly in Fig.2 It can be seen that the vertically extending boundary elements 2 have air-permeable areas with a filter-like retaining element 5. The horizontally extending boundary elements 12 are formed by closed boards. The air can flow out of a chamber 4 through the filter-like retaining elements 5 respectively into the left and / or right adjacent chamber 4 during the blowing of insulating material, which ensures a uniform and complete filling of a chamber 4 with insulating material. The openings for feeding the insulating material into the chambers 4 are in Fig.1 not closer shown.

Die senkrecht verlaufenden Begrenzungselemente 2 sind als tragende Leiterelemente mit Längsstreben 6 und Querstreben 7 ausgebildet. Das als Vlies, Netz oder Gaze ausgebildete, filterartige Rückhalteelement 5 ist jeweils zwischen den einen Freiraum des Begrenzungselements 2 umgrenzenden Längs- und Querstreben 6, 7 angeordnet und Überdeckt diesen vollständig. Das filterartige Rückhalteelement 5 ist dabei so feinmaschig oder feinporig, dass Partikel wie beispielsweise Flocken, Fasern, Körner, Streu, Pellets oder dergleichen einblasfähiges loses Isoliermaterial innerhalb der Kammer 4 gehalten werden kann, die mit diesem Isoliermaterial eingeförderte Transportluft jedoch praktisch ungehindert entweichen kann.The vertically extending boundary elements 2 are designed as load-bearing conductor elements with longitudinal struts 6 and cross struts 7. The designed as a nonwoven, mesh or gauze, filter-like retaining element 5 is in each case between the free space of the limiting element 2 bounding longitudinal and transverse struts 6, 7 and covers it completely. The filter-like retaining element 5 is so fine-meshed or fine-pored that particles such as flakes, fibers, grains, litter, pellets or the like einblasfähiges loose insulating material can be kept within the chamber 4, but with this transport material conveyed transport air can escape practically unhindered.

In Fig.2 ist erkennbar, dass zumindest die Begrenzungselemente 2 aus Schichtholz mit mehreren Brettschichten 8, 9, 10 bestehen. Für eine sichere und rundum dichte Befestigung des filterartigen Rückhalteelements 5 zwischen den Längs- und Querstreben 6, 7 ist es dabei vorteilhaft, wenn das filterartige Rückhalteelement 5 zwischen zwei benachbarten, miteinander verleimten Brettschichten 9, 10 der Begrenzungselemente 2 befestigt, insbesondere verleimt ist.In Fig.2 It can be seen that at least the boundary elements 2 consist of laminated wood with several board layers 8, 9, 10. For a secure and all-round tight fastening of the filter-like retaining element 5 between the longitudinal and transverse struts 6, 7, it is advantageous if the filter-like retaining element 5 between two adjacent, glued together board layers 9, 10 of the boundary elements 2 attached, in particular glued.
