Abstract

1. Process for diminishing the heat loss by the heat conduction of the joint flushings (5, 15) on the soffit and lintels of window- and door openings of buildings, characterized in that along the joint flushing (5, 15) prefabricated building elements are attached, preferably glued onto the inner wall instead of the inner wall plaster (8, 18), said prefabricated building elements consisting of an L-shaped outer shell (19, 20) of plaster board fastened to a hard foam slab (21) filling up flush to hollow space of the L.

Description

Die Erfindung betrifft ein Fertigteil für Bauwerke wie Wohn-und Bürohäuser, dessen Einbau an den Laibungen und Stürzen von Fenstern und Türen die durch die Kältebrücke des Zargenverstri- ches hervorgerufene Kälteausstrahlung im Innern des Bauwerkes erheblich zu vermindern gestattet und darüber hinaus bei Neubauten eine nicht unbeträchtliche Senkung der hohen Lohnkosten des konventionallen Einputzens, Einkachelns oder Vertäfelns ermöglicht. Die Erfindung ist nachstehend an Hand der Figuren näher erläutert.The invention relates to a prefabricated part for buildings such as residential and office buildings, the installation of which on the soffits and lintels of windows and doors significantly reduces the cold radiation inside the building caused by the cold bridge of the frame screed and, moreover, a not inconsiderable one in new buildings Reduce the high labor costs of conventional plastering, tiling or paneling. The invention is explained in more detail below with reference to the figures.

Figur 1 ist ein Horizontalschnitt durch ein Fenster bzw. eine Tür in konventioneller einschaliger Bauweise und Figur 2 ein entsprechender Horizontalschnitt durch ein Fenster bzw. eine Tür in konventioneller zweischaliger Bauweise.Figure 1 is a horizontal section through a window or door in a conventional single-shell design and Figure 2 is a corresponding horizontal section through a window or door in a conventional double-shell design.

In Figur 1 ist 1 das Verblendwerk, 2 das innere, z.B. KSL-Mauerwerk, 3 ist die Tür- oder Fensterzarge und 4 eine Mörtelfuge. 5 ist der Zargenverstrich, 6 eine häufig zur Abdichtung gegen Atmosphärilien vorgesehene in dauerelastischem Kitt eingebettete Profilleiste und 7 und 8 der Innenverputz.In Figure 1, 1 is the facing, 2 the inner, for example KSL masonry, 3 is the door or window frame and 4 is a mortar joint. 5 is the Zargenverstrich, 6 a frequently tmosphärilien for sealing against A provided embedded in a permanently elastic cement profile strip and 7 and 8 of the inner plaster.

In Figur 2 ist 11 die Außenschale, 12 die innere Schale des Mauerwerkes, 13 ist die Tür- oder Fensterzarge, 14 und 15 der zur Abdichtung erforderliche Zargenverstrich, 6 die gleiche Profilleiste wie in Figur 1 und 17 und 18 der innere Wandverputz.In Figure 2, 11 is the outer shell, 12 is the inner shell of the masonry, 13 is the door or window frame, 14 and 15 is the frame grouting required for sealing, 6 is the same profile strip as in Figures 1 and 17 and 18 is the inner wall plaster.

Da alle bekannten für den Zargenverstrich verwendbaren Materialien wesentlich bessere Wärmeleiter sind als Ziegel oder sonst übliche Baumaterialien für die Mauern, bildet der Zargenverstrich stets eine "Kältebrücke", längs der Kälte in das Innere des Bauwerkes kriecht und dann vor allem von der vom Innenwandverputz 8 bzw. 18 bedeckten Innenwandfläche in den Innenraum "strahlt". Diese Kälteeinströmung entlang des Zargenverstriches 5 bzw. 14, 15 kann durch den erfindungsgemäßen Isolier-Fertigbauteil erheblich vermindert werden. Dieser Bauteil ist in Figur 3 für sich allein und in den Figuren 4 und 5 nach seinem Einbau in der Fenster- bzw. Türöffnung dargestellt.Since all known materials that can be used for frame framing are much better heat conductors than bricks or other usual building materials for the walls, frame framing always forms a "cold bridge", creeps along the cold into the interior of the building and then, above all, from the interior wall plaster 8 or 18 covered interior wall surface "shines" into the interior. This inflow of cold along the frame spread 5 or 14, 15 can be considerably reduced by the prefabricated insulating component according to the invention. This component is shown in FIG. 3 on its own and in FIGS. 4 and 5 after it has been installed in the window or door opening.

Dieses Bauteil, das erfindungsgemäß vorzugsweise an Stelle des inneren Wandverputzes 8 bzw. 18 an aie Innenwand angebracht u. zw. vorzugsweise angeklebt wird, besteht im Wesentlichen aus einer L-förmigen Außenschale 19, 20 geeigneter Stärke aus Gipskarton wie Rigips und einer mit dieser Schale fest verbundenen, vorzugsweise verklebten, den Hohlraum des L ausfüllenden und ihn plan abschließenden Hartschaumplatte 21. Die aus zwei rechtwink- lig miteinander verbundenen Gipskartonplatten 19, 20 bestehende Außenschale ist zweckmäßig aus Platten der handelsüblichen Stärke von a = 12 mm gefertigt.This component, which according to the invention is preferably attached instead of the inner wall plaster 8 or 18 to the inner wall u. between. is preferably glued, consists essentially of an L-shaped outer shell 19, 20 of suitable thickness made of plasterboard such as plasterboard and a rigid foam plate 21 firmly connected to this shell, preferably glued, which fills the cavity of the L and closes it flat The outer shell is expediently made from plates with a standard thickness of a = 12 mm.

Die Gesamtdicke D des erfindungsgemäßen Fertigbautgiles soll im Idealfall etwa 42 mm betragen, entsprechend einer Dicke der Hartschaumplatte von d = 30 mm. Diese Abmessungen verbinden wirtschaftlichste Herstellungskosten mit optimaler Wärmedämmung, Feuersicherheit und Transportfestigkeit mit einer Gesamtdicke D, aie klein genug ist um weder beim Einbau noch beim Transport der Bauteile störend zu wirken und sind besonders geeignet für den Einbau in Neubauten, bei denen weder auf bereits vorhandenen Innenputz noch auf Verriegelungen o. dgl. Rücksicht genommen zu werden braucht. In diesem Falle können die erfindungsgemäßen Fertigbauteile einfach an die Innenwand geklebt werden und damit den Innrnverputz 8 bzw. 18 ersetzen,was den zusätzlichen Vorteil einer nicht unbeträchtlichen Lohnkostenersparnis mit sich bringt.The total thickness D of the prefabricated tile according to the invention should ideally be approximately 42 mm, corresponding to a thickness of the rigid foam plate of d = 30 mm. These dimensions combine the most economical production costs with optimal thermal insulation, fire safety and transport stability with a total thickness D that is small enough to not interfere with the installation or transport of the components and are particularly suitable for installation in new buildings where there is neither existing plaster still needs to be taken into account locks or the like. In this case, the prefabricated components according to the invention can simply be glued to the inner wall and thus replace the interior plaster 8 or 18, which has the additional advantage of not inconsiderable labor cost savings.

Für den nachträglichen Einbau in bereits bestehende Gebäude kann es u.U. notwendig oder zweckmäßig sein, die Gesamtdicke D zu reduzieren, was in gewissen Grenzen sowohl durch Verringerung der Wandungsstärke a der Gipskartonplatten 20, wie auch durch Verwendung dünnerer Hartschaumplatten 21 erzielt werden kann.For retrofitting in existing buildings, it may be necessary or expedient to reduce the total thickness D, which can be achieved within certain limits both by reducing the wall thickness a of the plasterboard 20, as well as by using thinner hard foam panels 21.

Die erfindungsgemäßen Fertigbauteile können in gleicher Weise und mit den gleichen vorteilhaften Wirkungen wie voranstehend für den Einbau an Laibungsflächen geschildert, auch an den Sturzflächen der Fenster- und Türöffnungen eingebaut werden.The prefabricated components according to the invention can also be installed on the lintel areas of the window and door openings in the same way and with the same advantageous effects as described above for installation on soffit surfaces.
