Abstract

A sound and heat insulating partition for overlying rooms consists of the inner layer of the external wall (1), the floor layer (2) and supporting wall casings (3), the inner layer of the exterior wall (1) being fixed, without contacting other components such as the floor (2) and beams (5), to spaced-apart trusses (4) which are fixed only at points on the outer longitudinal beams (6, 7). Preferably, the floor (2) comprises a footstep insulating material (9) consisting of a uniform mixture of 5-20 mm diameter stones and sawdust impregnated with boron salt, soda, lime and ammonium sulphate solution, laid on the underlying floor base without contacting other components.

Description

Die Erfindung betrifft eine trittschall-, körperschall- und wärmegedämmte Abtrennung überein­ anderliegender Räume im Holzskelettbau.The invention relates to an impact sound, structure-borne noise and heat-insulated separation other rooms in wooden skeleton construction.

Nachwachsende Rohstoffe wie Holz werden auch in Deutschland immer mehr im Wohnungsbau eingesetzt. Der immer knapper und teurer werdende Baugrund zwingt auch den Holzbau mehr­ geschossige Mehrfamilienhäuser und Bürohäuser zu errichten. Gerade bei übereinanderliegenden Wohnungen lassen sich im Rahmenbau die Nebenwegübertragungen des Luft- und Körper­ schalls nur mit stark die Baukosten erhöhenden Maßnahmen auf den nach DIN 4109, Schall­ schutz im Hochbau geforderten Werte reduzieren.Renewable raw materials such as wood are also increasingly used in residential construction in Germany used. The increasingly scarce and expensive building site also forces timber construction more to build multi-storey apartment buildings and office buildings. Especially with one on top of the other In the frame construction, apartments allow the bypass transmissions of the air and body sound only with measures that greatly increase the construction costs to DIN 4109, sound Reduce protection required in building construction.

Beim sehr verbreiteten Holzrahmenbau, aber auch beim Holzskelettbau läßt sich die Schall­ übertragung über die tragenden Bauteile, die die Lasten des Daches, der einzelnen Etagen usw. in die Fundamente ableiten, nicht mit einfachen Mitteln vermeiden.With the very common wood frame construction, but also with the wood skeleton construction, the sound can be transmission via the load-bearing components, the loads of the roof, the individual floors, etc. lead into the foundations, do not avoid using simple means.

Die nach der DIN 4109 z. B. empfohlenen trittschalldämmenden Deckenaufbauten für Holzbal­ kendecken sind aufwendig, sehr schwer und teuer.The according to DIN 4109 z. B. Recommended impact sound absorbing ceiling structures for wooden bal comforters are complex, very heavy and expensive.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Anordnung der Bauteile mit einem Wand- und Deckenaufbauten zu finden, die die Nachteile bekannter Konstruktionen nicht auf­ weist.The object of the present invention is to arrange the components with a Find wall and ceiling structures that do not have the disadvantages of known constructions points.

Erfindungsgemäß wird die Abtrennung von übereinanderliegenden Räumen so gestaltet, daß über tragende Bauteile keine direkte Schallübertragung möglich ist.According to the separation of superimposed rooms is designed so that No direct sound transmission is possible via load-bearing components.

Die raumbegrenzenden Flächen Fig. 1 Wände (1), Fußboden (2) und die Einhausung (3) der durchlaufenden Stützen (11) sind nicht in direktem Kontakt mit den Lasten tragenden Balken und Stützen der Holzskelettkonstruktion. Die Fußbodenfläche (2) und die Einhausung (3) der Stützen (11) wird mit eine Trittschallisoliermasse (9) gegen Luft- und Körperschall abgetrennt.The space-limiting surfaces Fig. 1 walls ( 1 ), floor ( 2 ) and the housing ( 3 ) of the continuous supports ( 11 ) are not in direct contact with the load-bearing beams and supports of the wooden skeleton construction. The floor surface ( 2 ) and the housing ( 3 ) of the supports ( 11 ) are separated from airborne and structure-borne noise with an impact sound insulation compound ( 9 ).

Diese Trittschallisoliermasse ist aus Steinen, Splitt oder Kiesel mit 5 bis 20 mm Größe herge­ stellt. Die Oberfläche der Steine wird mit heißem Harz in einer Mischtrommel benetzt und dann mit Sägemehl eingepudert, so daß sich eine Schicht auf der Oberfläche der Steine aufbaut und sich die Steine nicht mehr direkt berühren können. Das Lückenvolumen zwischen den Steinen wird mit Hobelspänen und Sägemehl ausgefüllt und erhöht die Wärmeisolierung des Gemisches. Damit das Trittschallisoliermaterial in feuerhemmender F 30 B Holzkonstruktionen verwendet werden kann und Nagetiere, Pilze und Insekten ferngehalten werden, wird die Sägespäne des Gemisches mit einer wäßrigen Lösung aus Borsalz, Soda, Kalk und Ammonsulfat in geeigneter Mischung besprüht. Dieses Material läßt sich auf der Baustelle im Selbstbau sehr preisgünstig herstellen, verarbeiten und hat überraschender Weise ideale trittschalldämmende Eigenschaften.This impact sound insulation is made of stones, grit or pebbles with a size of 5 to 20 mm poses. The surface of the stones is wetted with hot resin in a mixing drum and then powdered with sawdust so that a layer builds up on the surface of the stones and the stones can no longer touch each other directly. The gap volume between the stones is filled with wood shavings and sawdust and increases the thermal insulation of the mixture. So that the impact sound insulation material is used in fire-retardant F 30 B wooden constructions and rodents, fungi and insects are kept away, the sawdust of the Mix with an aqueous solution of boron salt, soda, lime and ammonium sulfate in a suitable Sprayed mixture. This material can be built very cheaply at the construction site manufacture, process and surprisingly has ideal impact sound insulation properties.

Die Innenschale (1) der Außenwand wird mit einem Fachwerkträger (4) der aus Latten (13 und 14) und Brettern (15) zusammengeschraubt oder genagelt wird. Dieser Fachwerkträger (4) wird nur außen an dem Längsbalken (6) und (7) punktförmig durch Schrauben oder Nägel befestigt, so daß die Innenschale (1) sonst keine weitere Berührung mit den anderen Bauteilen hat. Die Außenschale (8) der Außenwand ist auch nur an den Fachwerkträgern (4) befestigt. Die Fach­ werkträger (4) für die Befestigung der Wandschalen (1) und (8) sind im Abstand von ca. 600 bis 1000 mm angeordnet und bilden gleichzeitig die Abstandshalter zwischen den Wandschalen. Der Raum zwischen den Wandschalen (1 und 8 ) wird mit einer Schüttisolierung aus vorzugsweise nachwachsenden Rohstoffen gefüllt. The inner shell ( 1 ) of the outer wall is screwed or nailed together with a truss ( 4 ) made of slats ( 13 and 14 ) and boards ( 15 ). This lattice girder ( 4 ) is only attached to the outside of the longitudinal beams ( 6 ) and ( 7 ) at points by screws or nails, so that the inner shell ( 1 ) has no further contact with the other components. The outer shell ( 8 ) of the outer wall is also only attached to the truss girders ( 4 ). The trusses ( 4 ) for fastening the wall shells ( 1 ) and ( 8 ) are arranged at a distance of approx. 600 to 1000 mm and at the same time form the spacers between the wall shells. The space between the wall shells ( 1 and 8 ) is filled with bulk insulation made of preferably renewable raw materials.

Diese Schüttisolierung kann aus trockenen, porösen Pflanzenstielen, aus trockenen Halmen wie z. B. Stroh hergestellt werden, indem es mit einem scharfen, rotierendem Messer in Längen von vorzugsweise 3 bis 10 mm, maximal 30 mm abgeschnitten wird. Damit dieses Material auch in Bauwerken der Feuerwiderstandsklasse F 30 B eingesetzt werden kann und Nagetiere, Insekten, Pilze usw. das Material meiden, muß es sehr gleichmäßig mit einer wäßrigen Lösung aus z. B. Borsalz, Kalk, Soda, Ammonsulfat usw. besprüht werden, bis es die Baustoffklasse B2 hat.This bulk insulation can be made from dry, porous plant stems, from dry stalks such as e.g. B. Straw can be made by using a sharp, rotating knife in lengths of preferably 3 to 10 mm, maximum 30 mm is cut off. So that this material also in Buildings of fire resistance class F 30 B can be used and rodents, insects, Avoid mushrooms etc. the material, it must be very even with an aqueous solution of e.g. B. Boron salt, lime, soda, ammonium sulfate etc. are sprayed until it has building material class B2.

Die Wangen für die Tür- und Fensterrahmen, an denen die Innenschale (1) und die Außenschale (8) der Außenwand anschließen, werden nur mit den durchlaufenden Balken (5) und (6) starr verbunden und an dem Balken (7) körperschallabgekoppelt geführt. Mit dieser Anordnung erge­ ben sich Niedrigenergiehauser mit übereinanderliegenden Wohnungen, die überraschenderweise sehr hohe Luft-, Tritt- und Köperschalldämmung aufweisen.The cheeks for the door and window frames, to which the inner shell ( 1 ) and the outer shell ( 8 ) of the outer wall are connected, are only rigidly connected to the continuous beams ( 5 ) and ( 6 ) and guided to the beam ( 7 ) decoupled from structure-borne noise . This arrangement results in low-energy houses with apartments one above the other, which surprisingly have very high air, impact and structure-borne sound insulation.
