Definitions
- the invention relates to a working method for creating a walkable insulation for the upper floor ceiling in buildings with distributed on the floor slab erected stamps and placed thereon, supporting material plate, wherein the punch is formed from a pipe section, wherein the pipe longitudinal axis of the pipe section is arranged vertically in installation orientation , as well as a created Dämmungsup.
- Such walkable insulation is from the German utility model DE 20 2005 019 245 known to the applicant.
- Such walkable insulation has been used several times in the renovation of older buildings.
- the upper storey ceiling is the worst insulated component. Concrete ceilings are usually executed without insulation. Accordingly, the heat losses in the cold season are very large.
- the attic which is raised to the ceiling, heats up so much that even living rooms underneath it are undesirably warmed up.
- an insulation system was developed by the applicant, which has wood stamp on the new floor as a load-bearing wood-based panel, such as OSB or chipboard is placed.
- the cavity between the original raw ceiling (concrete ceiling) and the wood-based panel clamped by the wooden punches is then blown without joints, for example with a cellulose insulation material.
- This system has been adapted according to DE 20 2005 019 245 optimized that the wood stamp has been replaced by a stamp, the installation orientation in Cross-section to the vertical has a smaller compared to its area coverage cross-sectional area. It has also been proposed to use a pipe section, for example made of cardboard or plastic as a stamp. However, the construction of such walkable insulation was relatively expensive and sometimes led to undesirable shifts of the arranged under the load-bearing material plate pipe sections, so that a safe load bearing in parts of already laid surfaces could not be guaranteed.
- the pipe sections in particular cardboard tube sections before laying the walkable insulation already filled with the cellulose fluff provided for insulation are manageable, without the need for a separate fixation of the captured therein in the cylindrical interior flakes. Solely, it is necessary to press the cellulose flakes tightly pressed into the interior of the pipe section. It is thus possible to cut the pipe sections to the desired length, for example in a prefabrication stage, and to automatically fill them with the cellulose flakes. For this purpose, a separate cellulose flake filling and pressing device can also be used. The prepared filled with cellulose flakes pipe sections can then be transported to the site and placed there according to the next step. The installation is carried out in a predetermined grid that results from the size of the aufGHzden bearing material plates, for example, the grid can be 62.5 cm.
- the load distribution elements are small plate sections, for example square 15 x 15 cm, circular or preferably flat elongated as a board.
- the load distribution element is formed for example of natural wood, wood material or rigid sandwich material.
- the load distribution element has a high strength.
- it is suitable to receive fastening means, such as screws or nails frictionally.
- the load distribution element is designed as a flat elongated board and rests on at least two spaced-apart punches, which are on the board butt joints of the deposited thereon material plates.
- the boards provided as a load distribution element are placed on the stamp distributed in the grid on the blanket stamp that the Stirnspirefugen the adjoining in a series of material plates are each arranged centrally on a board. This ensures that the entire butt joint is supported by the board, so that unwanted overstressing and destruction of the tongue and groove joint on the frontal impact of the adjacent material plates can be avoided.
- the row is then shifted at least one pitch, so that no four bumps cross each other at one point.
- a high strength is realized at the abutting on their longitudinal sides of the material plates by the offset of the rows.
- the material plates In order to prevent the material plates from slipping apart, they are connected to one another in the region of the bearing on the load distribution element by nails or screws via the load distribution element. Characterized in that the fastening means (screw / nail) passes through the material plate and the load distribution element and preferably 2 to 3 cm in the Interior of the pipe section arranged underneath, is also reliably avoided that the pipe section could slip and migrate at a possibly slightly hollow surface produced from the material plates.
- both the dumping of cellulose flakes in the cavity between the built-up material plates and upper floor ceiling which should be done train by train when laying the material plates, or by blowing the cellulose flakes with known injection devices on appropriately provided or subsequently drilled filling openings.
- Fig. 1 the basic structure of a walk-in insulation is shown in a cut-out cross-section.
- a floor ceiling G which is for example a concrete ceiling
- stamp 1 spaced from one another stamp 1 are placed.
- the stamp 1 consists of a pipe section made of cardboard, which is filled with cellulose flakes 3 as an insulating material in its interior I filled.
- a load distribution element 22 on the as new walkable floor structure 2 suitable material plates 21, for example, wood-based panels (OSB or chipboard) are placed. Preference is given to material plates which have a tongue and groove connection or a two-layer overlapping division for load-bearing and support also on plate edges.
- the stamp 1 are preferably arranged in a fraction of the laying of the material plates to each other objected.
- Dry screed plates with a dimension of 59 cm x 244 cm
- the stamp 1 are placed, for example, at a distance of 59 cm to each other in parallel rows, each row is constructed with a distance of 61 cm.
- the dry screed plates can be placed on the provided with load distribution elements, erected stamp 1 that the edges and in particular the four corners of the dry screed plate are supported directly by punches 1.
- the plates are stored by at least one grid dimension of 61 cm, so that again the edges and the four corners of the dry screed plate rest on punches 1, but four plates never meet at one point.
- Fig. 2 shown schematically.
- the arranged under the plates 21 stamp 1 are shown for better orientation of their position by a circle.
- the positions of the nails 4 are represented by dots, as will be described later.
- Fig. 2 is the frontal butt joint of the juxtaposed in a row with tongue and groove material panels shown in phantom. These end-side joints lie respectively on the board-shaped load distribution elements 22 and are thus supported on both sides of the joint by the load distribution element 22. A breakout of the tongue and groove joint on this front side Joint is thus excluded.
- the load distribution element 22 is, for example, a wooden board in a thickness of 3 to 4 cm and thus serves as a front bump pad.
- fastening means 4 here nails
- at least one nail in the region of the load distribution element 22 per material plate 21 is nailed to the corner of the plate so that its downwardly projecting from the load distribution element 22 tip 41 of the nail 4 in the interior I, which is spanned by the pipe section 1, protrudes.
- cavity H is now poured either when laying the material plates 21 train by train insulation material manually or blown in a suitable manner after installation.
- the cavity H is thus completely filled with insulating material 3, for example cellulose flakes.

Abstract
Description
Die Erfindung betrifft ein Arbeitsverfahren zum Erstellen einer begehbaren Dämmung für die obere Geschossdecke in Gebäuden mit auf der Geschossdecke verteilt aufgestellten Stempeln und einer darauf gelegten, tragenden Werkstoffplatte, wobei der Stempel aus einem Rohrabschnitt gebildet ist, wobei die Rohrlängsachse des Rohrabschnitts in Einbauorientierung vertikal angeordnet ist, sowie einen damit erstellten Dämmungsaufbau.The invention relates to a working method for creating a walkable insulation for the upper floor ceiling in buildings with distributed on the floor slab erected stamps and placed thereon, supporting material plate, wherein the punch is formed from a pipe section, wherein the pipe longitudinal axis of the pipe section is arranged vertically in installation orientation , as well as a created Dämmungsaufbau.
Eine derartige begehbare Dämmung ist aus dem deutschen Gebrauchsmuster
Dafür wurde von der Anmelderin ein Dämmsystem entwickelt, das Holzstempel aufweist, auf die als neuer Fußboden eine tragende Holzwerkstoffplatte, beispielsweise OSB- oder Spanplatte aufgelegt wird. Der von den Holzstempeln aufgespannte Hohlraum zwischen ursprünglicher Rohdecke (Betondecke) und der Holzwerkstoffplatte wird dann beispielsweise mit einem Zellulosedämmstoff fugenfrei ausgeblasen.For this purpose, an insulation system was developed by the applicant, which has wood stamp on the new floor as a load-bearing wood-based panel, such as OSB or chipboard is placed. The cavity between the original raw ceiling (concrete ceiling) and the wood-based panel clamped by the wooden punches is then blown without joints, for example with a cellulose insulation material.
Dieses System wurde dahingehend gemäß
Daher ist es Aufgabe der Erfindung, ein Arbeitsverfahren zum Erstellen einer begehbaren Dämmung anzugeben, das eine schnelle und damit wirtschaftliche Verlegung und eine sichere Fixierung der als Stempel dienenden Rohrabschnitte ermöglicht. Ferner ist es Aufgabe der Erfindung, einen Dämmungsaufbau anzugeben, der eine hohe Stabilität aufweist.Therefore, it is an object of the invention to provide a working method for creating a walkable insulation, which allows a fast and thus economical installation and secure fixing of serving as a stamp pipe sections. It is another object of the invention to provide a Dämmungsaufbau having a high stability.
Gelöst wird diese Aufgabe nach einem Arbeitsverfahren gemäß Anspruch 1 sowie einem Dämmungsaufbau nach Anspruch 4.This object is achieved by a method according to
Überraschenderweise hat sich gezeigt, dass die Rohrabschnitte, insbesondere Papperohrabschnitte vor der Verlegung der begehbaren Dämmung bereits mit dem zur Dämmung vorgesehenen Zelluloseflocken befüllt handhabbar sind, ohne dass es einer gesonderten Fixierung der darin im zylindrischen Innenraum aufgenommenen Flocken bedarf. Einzig und allein ist es erforderlich, die Zelluloseflocken fest zusammengepresst in den Innenraum des Rohrabschnittes zu pressen. Es ist somit möglich, die Rohrabschnitte beispielsweise in einer Vorfertigungsstufe auf die gewünschte Länge zu schneiden, und automatisiert mit den Zelluloseflocken zu befüllen. Dazu kann auch eine gesonderte Zelluloseflockenfüll- und -pressvorrichtung verwendet werden. Die vorbereiteten mit Zelluloseflocken befüllten Rohrabschnitte können dann zur Baustelle transportiert werden und dort entsprechend des nächsten Arbeitsschrittes aufgestellt werden. Die Aufstellung erfolgt in einem vorbestimmten Rastermaß, dass sich aus der Größe der aufzulegenden tragenden Werkstoffplatten ergibt, beispielsweise kann das Rastermaß 62,5 cm betragen.Surprisingly, it has been shown that the pipe sections, in particular cardboard tube sections before laying the walkable insulation already filled with the cellulose fluff provided for insulation are manageable, without the need for a separate fixation of the captured therein in the cylindrical interior flakes. Solely, it is necessary to press the cellulose flakes tightly pressed into the interior of the pipe section. It is thus possible to cut the pipe sections to the desired length, for example in a prefabrication stage, and to automatically fill them with the cellulose flakes. For this purpose, a separate cellulose flake filling and pressing device can also be used. The prepared filled with cellulose flakes pipe sections can then be transported to the site and placed there according to the next step. The installation is carried out in a predetermined grid that results from the size of the aufzulegenden bearing material plates, for example, the grid can be 62.5 cm.
Die Lastverteilungselemente sind kleine Plattenabschnitte, beispielsweise quadratisch 15 x 15 cm, kreisrund oder bevorzugt flächig langgestreckt als Brett. Das Lastverteilungselement ist beispielsweise aus Naturholz, Holzwerkstoff oder biegesteifem Sandwichwerkstoff gebildet. Damit weist das Lastverteilungselement eine hohe Festigkeit auf. Ferner ist es geeignet, Befestigungsmittel, wie Schrauben oder Nägel kraftschlüssig aufzunehmen. Beim Auflegen der tragenden Werkstoffplatten wird darauf geachtet, dass an aneinanderstoßenden Ecken von zwei stirnseitig aneinanderstoßenden Platten auf jeden Fall ein Lastverteilungselement mit darunter angeordnetem Rohrabschnitt als Stempel angeordnet sind. Bevorzugt ist das Lastverteilungselement als flächig langgestrecktes Brett ausgebildet und liegt auf wenigstens zwei beabstandet zueinander angeordneten Stempeln auf, wobei sich auf dem Brett Stoßfugen der darauf abgelegten Werkstoffplatten befinden. Insbesondere wird bei den bekannten zu verlegenden Werkstoffplatten die als Lastverteilungselement vorgesehenen Bretter so auf die im Rastermaß auf der Rohdecke verteilten Stempel aufgelegt, dass die Stirnstoßfugen der in einer Reihe aneinandergrenzenden Werkstoffplatten jeweils mittig auf einem Brett angeordnet sind. Damit ist gewährleistet, dass die gesamte Stoßfuge von dem Brett unterstütz wird, so dass unerwünschte Überbeanspruchungen und Zerstörungen der Nut-/Federverbindung an dem stirnseitigen Stoß der aneinanderliegenden Werkstoffplatten vermieden werden können. Bei der nächsten Reihe von Werkstoffplatten, die verlegt werden, wird die Reihe dann mindestens um ein Rastermaß verschoben, so dass sich keine vier Stöße an einem Punkt kreuzweise treffen. Somit ist auch eine hohe Festigkeit an den an ihren Längsseiten aneinanderstoßenden Werkstoffplatten durch den Versatz der Reihen realisiert.The load distribution elements are small plate sections, for example square 15 x 15 cm, circular or preferably flat elongated as a board. The load distribution element is formed for example of natural wood, wood material or rigid sandwich material. Thus, the load distribution element has a high strength. Furthermore, it is suitable to receive fastening means, such as screws or nails frictionally. When placing the load-bearing material plates is taken to ensure that at abutting corners of two frontally abutting plates in any case a load distribution element arranged underneath pipe section are arranged as a stamp. Preferably, the load distribution element is designed as a flat elongated board and rests on at least two spaced-apart punches, which are on the board butt joints of the deposited thereon material plates. In particular, in the known material plates to be laid, the boards provided as a load distribution element are placed on the stamp distributed in the grid on the blanket stamp that the Stirnstoßfugen the adjoining in a series of material plates are each arranged centrally on a board. This ensures that the entire butt joint is supported by the board, so that unwanted overstressing and destruction of the tongue and groove joint on the frontal impact of the adjacent material plates can be avoided. For the next set of slabs of material being laid, the row is then shifted at least one pitch, so that no four bumps cross each other at one point. Thus, a high strength is realized at the abutting on their longitudinal sides of the material plates by the offset of the rows.
Um ein Auseinanderrutschen der Werkstoffplatten zu verhindern, werden diese im Bereich der Auflagerung auf dem Lastverteilungselement durch Nägel oder Schrauben über das Lastverteilungselement untereinander verbunden. Dadurch, dass das Befestigungsmittel (Schraube/Nagel) durch die Werkstoffplatte und das Lastverteilungselement hindurchgreift und bevorzugt 2 bis 3 cm in den Innenraum des darunter angeordneten Rohrabschnitts reicht, wird auch sicher vermieden, dass der Rohrabschnitt bei einer etwaig leicht hohl liegenden aus den Werkstoffplatten erzeugten Fläche verrutschen und abwandern könnte.In order to prevent the material plates from slipping apart, they are connected to one another in the region of the bearing on the load distribution element by nails or screws via the load distribution element. Characterized in that the fastening means (screw / nail) passes through the material plate and the load distribution element and preferably 2 to 3 cm in the Interior of the pipe section arranged underneath, is also reliably avoided that the pipe section could slip and migrate at a possibly slightly hollow surface produced from the material plates.
Diese Gefahr besteht insbesondere beim Verfüllen des zwischen den tragenden Werkstoffplatten und der oberen Geschossdecke aufgebauten Hohlraums mit Zelluloseflocken, da diese möglicherweise die Rohrabschnitte vor sich hertreiben könnten, insbesondere beim Verfüllen durch Einblasen.In particular, this risk exists when filling the cellulosic fluff cavity formed between the load-bearing material panels and the upper floor slab, as these could possibly drive the pipe sections in front of them, in particular during filling by blowing.
Als Verfüllungsmethoden eignet sich sowohl das Einschütten von Zelluloseflocken in den Hohlraum zwischen aufgebauten Werkstoffplatten und oberer Geschossdecke, was dann allerdings Zug um Zug beim Verlegen der Werkstoffplatten erfolgen sollte, oder durch Einblasen der Zelluloseflocken mit bekannten Einblasvorrichtungen über entsprechend vorgesehene oder nachträglich eingebohrte Füllöffnungen.As filling methods, both the dumping of cellulose flakes in the cavity between the built-up material plates and upper floor ceiling, which should be done train by train when laying the material plates, or by blowing the cellulose flakes with known injection devices on appropriately provided or subsequently drilled filling openings.
