Abstract

The support and vibration damping system may be used to strengthen an existing wooden floor in a building. It has a support block with a central beam (20) pressing on the midpoint of the plastered underside (16,18) of the floor. The beam is positioned under a main existing floor support beam (10). There is a spring member (24) under and extending either side of the beam, covered with sound insulating material (26). The beam and sound insulation are supported on a length adjustable rod standing on a broad foot resting on the underfloor.

Description

Die Erfindung betrifft ein Verfahren zur Erhöhung der Tragfähigkeit, Steifigkeit und Schwingungsdämpfung einer Holzbalkendeckenanordnung nach dem Oberbegriff des Anspruchs 1 und eine Holzbalkendeckenanordnung mit erhöhter Tragfähigkeit, Steifigkeit und Schwingungsdämpfung nach dem Oberbegriff des Anspruchs 4.The invention relates to a method for increasing the load capacity, Rigidity and vibration damping of a wooden beam ceiling arrangement according to the preamble of claim 1 and a wooden beam ceiling arrangement with increased load capacity, Stiffness and vibration damping according to the preamble of Claim 4.

Einfache Holzbalkendeckenanordnungen aus tragenden Holzbalken mit einem oberen Dielenbelag, einer Gefachausfallung und einer geschlossenen Untersicht genügen nicht den Anforderungen an den Mindestschallschutz. Bekannte Sanierungsmaßnahmen zur verbesserung des Luft- und Trittschallschutzes sind:

  • a) Aufbringen eines schwimmenden Nass- oder Trockenestrichs, eines weichen Bodenbelags, eventuell einer zusätzlichen Beschwerung auf der Oberseite der Decke,
  • b) Einbau einer federnd abgehängten Unterdecke mit Mineralwolle-Bedämpfung auf der Unterseite der Decke und
  • c) Ausfüllen der Gefache mit Masse und Bedämpfung.
    • Simple wooden beam ceiling arrangements of load-bearing wooden beams with an upper plank covering, a Gefachausfallung and a closed lower view do not meet the requirements for the minimum sound insulation. Known remedial measures to improve the air and impact sound insulation are:
  • a) applying a floating wet or dry screed, a soft floor covering, possibly an additional weight on the top of the ceiling,
  • b) Installation of a spring suspended ceiling with mineral wool damping on the underside of the ceiling and
  • c) filling the compartments with mass and damping.

    • Mit diesen Maßnahmen lassen sich die Anforderungen an den Mindestschallschutz nach DIN 4109 erfüllen. Dennoch ist das Ergebnis oft unbefriedigend, weil die Decken nach wie vor erschütterungsempfindlich sind und dröhnen, d. h. beim Begehen deutlich wahrnehmbare Erschütterungen und tieffrequente Geräusche verstärkt übertragen. Vielfach dürfen alte Holzbalkendeckenanordnungen nicht oder nur in geringem Umfang zusätzlich belastet werden, so dass sich von den genannten Sanierungsmaßnahmen nur Teile ausführen lassen. Eine notwendige statische Ertüchtigung erfolgt im Allgemeinen durch seitliche Verstärkung der Holzbalken. Da diese Maßnahme das Öffnen und Entkernen der Gefache erfordert, werden sie wegen des hohen Aufwandes nur selten ausgeführt. With these measures, the requirements of the Minimum noise protection to comply with DIN 4109. Nevertheless, that is Result often unsatisfactory, because the blankets are still susceptible to vibration are and roar, d. H. when committing clearly noticeable vibrations and low-frequency noises amplified transfer. Often, old wood beam ceiling arrangements allow not or only to a small extent in addition be burdened, so that by the mentioned remedial measures only have parts carried out. A necessary static reinforcement is generally done by lateral Reinforcement of the wooden beams. Because this measure the opening and Coreing the compartments requires, they are because of the high Effort rarely performed.

    Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Erhöhung der Tragfähigkeit, Steifigkeit und Schwingungsdämpfung einer Holzbalkendeckenanordnung sowie eine Holzbalkendeckenanordnung mit erhöhter Tragfähigkeit, Steifigkeit und Schwingungsdämpfung anzugeben, die sich auf Maßnahmen auf der Unterseite einer vorhandenen Holzbalkendecke beschränken und ein Öffnen und Entkernen der Gefache erübrigen.The invention has for its object to provide a method for Increasing load capacity, rigidity and vibration damping a wooden beam ceiling arrangement as well as a wooden beam ceiling arrangement with increased load capacity, rigidity and Specify vibration damping, which refers to measures on the Restrain underside of an existing wooden beamed ceiling and an opening and coring of the compartments unnecessary.

    Diese Aufgabe wird bei einem Verfahren nach dem Oberbegriff des Anspruchs 1 durch die Merkmale dieses Anspruchs und bei einer Holzbalkendeckenanordnung nach dem Oberbegriff des Anspruchs 4 durch die Merkmale jenes Anspruchs gelöst.This task is in a method according to the preamble of claim 1 by the features of this claim and in a wooden beam ceiling arrangement according to the preamble of the claim 4 solved by the features of that claim.

    Weiterbildungen und vorteilhafte Ausgestaltungen ergeben sich aus den jeweiligen Unteransprüchen.Further developments and advantageous embodiments will be apparent from the respective subclaims.

    Erfindungsgemäß wird bei einer Holzbalkendeckenanordnung eine statische Ertüchtigung von tragenden Holzbalken durch Unterspannen der Holzbalken mit Holzbohlen erreicht. Die Holzbohlen werden in Achsrichtung der Holzbalken ausgerichtet und mit Abstand zu den tragenden Holzbalken positioniert. Als vertikaler Abstandshalter eignet sich der vorhandene Aufbau aus Putz auf Putzträger und Sparschalung. Ist der Putz auf Putzträger und Sparschalung nicht vorhanden, z.B. bei einer sichtbaren Holzbalkendecke oder bei der Herstellung neuer Holzbalkendecken, so ist ein gesonderter Abstandshalter erforderlich.According to the invention in a wooden beam ceiling arrangement a static reinforcement of load-bearing wooden beams by clamping the wooden beams reached with wooden planks. The wooden planks are aligned in the axial direction of the wooden beams and positioned at a distance to the supporting wooden beams. When vertical spacer is the existing structure from plaster on plaster base and Sparschalung. Is the plaster on Plaster backing and saving formwork not available, e.g. at a visible wooden beam ceiling or in the manufacture of new Wooden beamed ceilings, so a separate spacer is required.

    Durch eine vertikal aufwärts gerichtete Kraft, die mittig in die Holzbohle und über die Abstandshalter auch in die Holzbalken eingeleitet wird, geht die vorhandene Durchbiegung des tragenden Holzbalkens ganz oder teilweise zurück. Durch schubfeste Verschraubung der Holzbohle mit dem Holzbalken wird diese Geometrie auch nach Lösung der äußeren Kraft weitgehend beibehalten und die vorhandene ständige Last vom weichen Holzbalkenquerschnitt auf den durch die schubfeste Verschraubung mit der zusätzlichen Holzbohle versteiften Verbundquerschnitt umgelagert.By a vertical upward force centered in the wooden plank and the spacers also in the wooden beams is initiated, the existing deflection of the supporting wooden beams in whole or in part. By Shock-proof screwing of the wooden plank with the wooden beam This geometry is largely after solving the external force maintain and soften the existing constant load Wooden beam cross-section on the through the shear-resistant screw connection stiffened with the additional wooden plank composite cross-section rearranged.

    Vorzugsweise werden zur schubfesten Verschraubung Vollgewindeschrauben durch die Holzbohle schräg, bzw. senkrecht nach oben in den Holzbalken geschraubt, im mittleren Bereich wechselweise schräg zu einer Vertikalen und im Auflagerbereich sowohl schräg von unten zum jeweiligen Auflager gerichtet als auch senkrecht verlaufend. Preferably, full-thread screws are used for shear-resistant screwing through the wooden plank at an angle, or vertically to screwed in the top of the wooden beams, alternately in the middle area oblique to a vertical and in the support area both obliquely directed from below to the respective support as also perpendicular.

    Die Vollgewindeschrauben bilden so Verbindungsmittel, die statisch betrachtet die zug- und druckfesten Schrägstäbe eines versteckten Fachwerkbinders mit Holzbalken als Obergurt und Holzbohle als Untergurt darstellen. Während im mittleren Bereich ausschließlich Schrägstäbe vorhanden sind, muss aus Montagegründen in der Nähe des Auflagers ein Wechsel des Fachwerksystems von ausschließlich Schrägstäben zu vertikalen Druckstäben und schrägen zum Auflager hin weisenden Zugstäben erfolgen.The full thread screws thus form connecting means, the statically considered the tension- and pressure-resistant diagonal bars of a Hidden truss with wooden beams as upper flange and represent wood plank as a lower flange. While in the middle Area only oblique bars are present, must be off Mounting reasons near the support a change of Truss system from only oblique bars to vertical Pressure rods and oblique to the support pointing Zugstäben respectively.

    Das statische System stellt einen durch Überhöhung und Schubbewehrung vorgespannten Holzbalken dar, der im Gebrauchs- und Bruchlastfall ein zum Spannbeton analoges Tragverhalten zeigt, weil das Kräftepaar aus dem vorwiegend druckbeanspruchten oberen Holzbalken und der zugbelasteten unteren Holzbohle einen größeren Hebelarm bildet und damit wesentlich höhere Momente aufnehmen kann als vorher.The static system represents one by elevation and shear reinforcement prestressed wooden beams used in utility and Break load case a prestressed concrete analogous carrying behavior shows because the pair of forces from the predominantly pressurized upper wooden beams and the tensile lower Wooden plank forms a larger lever arm and thus essential can record higher moments than before.

    Die Vollgewindeschrauben folgen hinsichtlich Abstand und Anzahl der Lagen dem Querkraftverlauf, der von der Mitte der Holzbalken zum Auflager hin ansteigt. The full thread screws follow in terms of distance and number the positions of the transverse force distribution, that of the middle of the Wooden beams rise towards the support.

    Der Abstandshalter zwischen Balken und Bohle kann durch den vorhandenen Putz auf Unterkonstruktion oder eine neu anzuordnende Holzwolleleichtbauplatte gebildet sein.The spacer between beam and screed can be replaced by the existing plaster on substructure or a newly arranged Made of wood wool lightweight panel.

    Bei nicht vorhandenem Putz auf Unterkonstruktion eignet sich als Abstandshalter eine Holzwolleleichtbauplatte der Dicke 25 bis 40 mm in besonderer Weise, weil deren Perforation zu noch besserer Bedämpfung der Balkengefache führt.If there is no plaster on the substructure, it is suitable as spacer, a wooden wool lightweight panel of thickness 25 to 40 mm in a special way, because their perforation too better attenuation of the bar gauges leads.

    Unter den Holzbohlen kann eine federnd abgehängte Untersicht angeordnet werden.Under the wooden planks can a springy suspended underside to be ordered.

    Hierbei übernehmen die Holzbohlen die Funktion einer sicheren und besser ausgerichteten Unterkonstruktion für die Unterdecke und bilden gleichzeitig Gefache zur Bedämpfung des Hohlraums zwischen Putz und Beplankung zwecks Verbesserung des Schallschutzes.Here, the wooden planks take over the function of a safe and better oriented substructure for the lower ceiling and at the same time form compartments for damping the cavity between plaster and planking to improve the Sound insulation.

    Der Vorteil des erfindungsgemäßen Verfahrens und der Holzbalkendeckenanordnung besteht darin, dass infolge der versteifung des Systems die Wirksamkeit konventioneller Maßnahmen zur Verbesserung des Luft- und Trittschallschutzes zusätzlich erhöht wird, bzw. dass bei einer alten, möglicherweise nicht mehr so tragfähigen Holzbalkendeckenanordnung überhaupt erst die genannten konventionellen Maßnahmen zur Verbesserung des Luft- und Trittschallschutzes durchführbar sind.The advantage of the method according to the invention and the wooden beam ceiling arrangement is that as a result of stiffening the effectiveness of conventional measures to improve the air and impact sound insulation additionally is increased, or that in an old, may not more so viable wood beam ceiling arrangement in the first place the said conventional measures to improve the Air and impact protection are feasible.

    Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels sowie grafischen Darstellungen, die in der Zeichnung dargestellt sind, näher erläutert.The invention will be described below with reference to an exemplary embodiment as well as graphic representations included in the drawing are illustrated, explained in more detail.

    Bei der Darstellung nach Fig. 1 besteht die vorhandene Holzbalkendecke aus tragenden Holzbalken 10 mit einem Dielenbelag 12 auf der Oberseite, einer Gefachfüllung 14, sowie einer Sparschalung mit Putzträger 16 und Putz 18 auf der Unterseite. Bei der erfindungsgemäßen Holzbalkendeckenanordnung dient die vorhandene Sparschalung mit Putzträger 16 und Putz 18 als Abstandshalter für eine an der Unterseite angebrachte Holzbohle 20, die mit dem tragenden Holzbalken 10 der ursprünglichen Holzbalkendecke durch Schrauben 22 schubfest verschraubt ist.In the illustration of FIG. 1, the existing wooden beam ceiling made of load-bearing wooden beams 10 with a floor covering 12 on the top, a Gefachfüllung 14, and a Sparschalung with plaster base 16 and plaster 18 on the bottom. In the wooden beam ceiling arrangement according to the invention is used the existing saving formwork with plaster base 16 and plaster 18 as Spacer for a wooden plank attached to the underside 20, the original with the wooden beams 10 Wooden beam ceiling bolted by screws 22 shear-resistant is.

    Ist der Putz auf Putzträger und Sparschalung nicht vorhanden, z.B. bei einer sichtbaren Holzbalkendecke oder bei der Herstellung neuer Holzbalkendecken, so eignet sich als Abstandshalter eine Holzwolleleichtbauplatte der Dicke 25 bis 40 mm in besonderer weise, weil deren Perforation zu noch besserer Bedämpfung der Balkengefache führt.If the plaster does not exist on plaster base and saving formwork, e.g. on a visible wooden beam ceiling or in the production new wooden beamed ceilings, so is suitable as a spacer a wood wool lightweight panel of thickness 25 to 40 mm in particular, because their perforation to even better Damping the Beamfache leads.

    Die Holzbohlen 20 bilden eine gut ausgerichtete Unterkonstruktion für eine federnd abgehängte Deckenuntersicht 24 und einen ausreichenden Zwischenraum zur Anordnung schalldämmender Materialien 26.The wooden planks 20 form a well-aligned substructure for a spring-suspended ceiling soffit 24 and a sufficient space for the arrangement of sound-absorbing Materials 26.

    Fig. 2 zeigt die Darstellung des Montagevorgangs zur Unterspannung der Holzbalken 10 mit Holzbohlen 20. Eine vorgebohrte Bohle wird mittels Schalungsstütze 28 und Hydraulik vertikal nach oben gedrückt. Diese überträgt die Kraft über den Abstandshalter, z.B. Putz 18 und Sparschalung 16 bzw. eine Holzwolleleichtbauplatte, in den darüber liegenden Holzbalken 10. Die vorhandene Durchbiegung des Holzbalkens 10 wird dabei teilweise oder ganz reduziert. Auf der Unterseite der Schalungsstütze 28 wird die Reaktionskraft über eine Lastverteilung 30 auf eine größere Fläche des Fußbodens 32 verlagert, um eine Durchbiegung des Fußbodens 32 zu vermindern.Fig. 2 shows the representation of the mounting operation for undervoltage the wooden beam 10 with wooden planks 20. A pre-drilled Bohle is vertical by means of formwork support 28 and hydraulic pushed up. This transmits the power over the Spacers, e.g. Plaster 18 and saving formwork 16 or one Wood wool lightweight panel, in the wooden beams above 10. The existing deflection of the wooden beam 10 is doing partially or completely reduced. On the underside of the formwork support 28, the reaction force is via a load distribution 30 is displaced to a larger area of the floor 32, to reduce deflection of the floor 32.

    Auf der Oberseite der Schalungsstütze 28 wird die Last über eine kleinere Lastverteilung 34 in den mittleren Bereich der Holzbohle 20 eingeleitet. Die so vorgespannte Konstruktion aus Holzbohle 20 und Holzbalken 10 wird nun von den Auflagern 36, 38 beginnend schubfest verschraubt.On the top of the formwork support 28, the load is over a smaller load distribution 34 in the middle region of Wood pile 20 initiated. The prestressed construction wooden plank 20 and wooden beams 10 will now be supported by the supports 36, 38 screwed down shear-resistant.

    Beim Absenken der Schalungsstütze 28 wird der Balken 10 durch den Schubverbund mit der Bohle 20 vorgespannt. Dabei erfolgt die Umlagerung der vorhandenen ständigen Last vom weichen Holzbalken 10 auf den versteiften Verbundquerschnitt. Die gleichzeitige Umlagerung der inneren Kräfte und Spannungen ist in Fig. 5 dargestellt. Die Unterspannung und Lastumlagerung wird, von den Streichbalken an der Wand beginnend, zur Mitte der Decke fortgesetzt und mit einem Laser höhenmäßig kontrolliert.When lowering the formwork support 28 of the beam 10 is through the thrust composite with the screed 20 biased. This takes place the rearrangement of the existing permanent load from the soft Wooden beam 10 on the stiffened composite cross section. The simultaneous rearrangement of internal forces and stresses is shown in Fig. 5. The undervoltage and load transfer is starting from the painting on the wall, to Center of the ceiling continued and with a laser in terms of height controlled.

    Zur Veranschaulichung der Wirkungsweise der durch die Schalungsstütze 28 erzielten Vorspannung durch Überhöhung zeigt Fig. 3 eine übertriebene Darstellung der Durchbiegung von Holzbohle 20 und Holzbalken 10, wobei der Holzbalken 10 und die Holzbohle 20 nach oben hin durchgebogen sind. Der Holzbalken 10 und die Holzbohle 20 sind schubfest verschraubt, wobei die Schrauben 22 im mittleren Balkenbereich Schrägstäbe bilden und zu den Auflagern 36, 3B hin zu vertikalen Druckstäben und schrägen zu den Auflagern hin weisenden Zugstäben wechseln. Der Wechsel zu vertikalen Druckstäben ist aus Montagegründen erforderlich, da wegen der Wände im Bereich der Auflager 36, 38 eine Schrägverschraubung von unten, vom Auflager weg gerichtet, nicht realisierbar ist.To illustrate the mode of action of the formwork support 28 achieved bias by elevation shows Fig. 3 is an exaggerated representation of the deflection of Wood beam 20 and wooden beams 10, the wooden beams 10 and the wood plank 20 are bent upwards. The wooden beam 10 and the wood plank 20 are bolted shear-resistant, the screws 22 in the middle beam area oblique rods form and to the supports 36, 3B towards vertical pressure bars and oblique to the supports pointing Zugstäben switch. The change to vertical pressure bars is for assembly reasons required because of the walls in the area of Supports 36, 38 a diagonal fitting from below, from the support directed away, not realizable.

    Fig. 4 zeigt eine grafische Darstellung der Durchbiegung über der Last bei einem Balken ohne Unterspannung und mit Unterspannung, die in einem Lastverfvrmungsversuch ermittelt wurde. In beiden Fällen ergibt sich ein lineares Lastverformungsverhalten ohne bleibende Verformungen bei Mehrfachbelastungen. Die erfindungsgemäße Maßnahme führt im Lastverformungsversuch zu einer Verdoppelung der Steifigkeit gegenüber dem Einzelbalken. Dies lässt den Schluss zu, dass die Tragfähigkeit der Holzbalkendecke wesentlich verbessert wird. Dadurch kann auch bei alten und möglicherweise nicht mehr so tragfähigen Balkenquerschnitten besonders bei größeren Spannweiten eine sehr kostengünstige und wirtschaftliche Verbesserung des Tragsystems erzielt werden.Fig. 4 shows a graphical representation of the deflection over the load of a beam without undervoltage and undervoltage, which was determined in a load test attempt. In both cases results in a linear load deformation behavior without permanent deformation at multiple loads. The measure according to the invention leads in the load deformation test to a doubling of rigidity the single bar. This leads to the conclusion that the carrying capacity the beamed ceiling is significantly improved. Thereby can also be old and maybe not like that anymore load-bearing beam cross-sections, especially for larger spans a very cost effective and economical improvement of the support system can be achieved.

    Fig. 5 zeigt den Querschnitt durch einen Holzbalken 10 mit einer im Abstand dazu angeordneten und mit dem Holzbalken 10 schubfest verschraubten Holzbohle 20. Links neben der Darstellung ist der Spannungsverlauf dargestellt, der im Holzbalken 10 ohne Verbund auftreten würde. Die rechte Darstellung zeigt den Spannungsverlauf des Verbundsystems aus Holzbalken 10 und schubfest verspannter Holzbohle 20. Die Figur zeigt, dass die Erfindung durch die Lastumlagerung auch zu einer Spannungsumlagerung führt, die trotz Verdoppelung der äußeren Belastung den alten Holzbalken 10 schont und die neue Bohle 20 gemäß ihrer berechenbaren Tragfähigkeit auslastet.Fig. 5 shows the cross section through a wooden beam 10 with a spaced apart and with the wooden beams 10th Schubfest bolted wooden plank 20. Left next to the illustration the voltage curve is shown in the wooden beam 10 would occur without composite. The right representation shows the voltage curve of the composite system of wooden beams 10 and shear-resistant wooden plank 20. The figure shows that the invention by the load transfer also too a voltage rearrangement leads, despite doubling the external stress spares the old wooden beams 10 and the new Bohle 20 according to their calculable load capacity.

    Fig. 6 zeigt eine grafische Darstellung der Luftschalldämmung über der Frequenz. Erkennbar ist, dass in dem maßgebenden Frequenzbereich zwischen 100 und 3150 Hz die Luftschalldämmung der ursprünglichen Decke durch die Unterspannung deutlich verbessert wird.Fig. 6 shows a graphic representation of the airborne sound insulation over the frequency. It is recognizable that in the authoritative Frequency range between 100 and 3150 Hz the airborne sound insulation the original ceiling due to the undervoltage clearly is improved.

    Fig. 7 zeigt.eine grafische Darstellung des Trittschallpegels über der Frequenz ebenfalls für eine konventionelle Holzbalkendecke und eine unterspannte Decke mit weichem Bodenbelag. Auch hier ist innerhalb des maßgeblichen Frequenzbereichs die deutliche Verbesserung des Trittschallschutzes ersichtlich.Fig. 7 shows a graphic representation of the impact sound level above the frequency also for a conventional beamed ceiling and an underfloor ceiling with soft flooring. Again, within the relevant frequency range, the Significant improvement in the impact sound protection visible.

    Die Fig. 6 und 7 machen deutlich, dass die konventionellen Schallverbesserungsmaßnahmen durch die Versteifung des Tragsystems infolge der Unterspannung, auch ohne zusätzliche Beschwerung der Decke, deutlich größere Verbesserungsmaße erzielen als einfache Holzbalkendecken, so dass die Anforderungen des erhöhten Schallschutzes nach DIN 4109 , Beibl. 2, erfüllt werden. Darüber hinaus sind Erschütterungen fast nicht mehr wahrnehmbar.Figs. 6 and 7 make it clear that the conventional Sound improvement measures through the stiffening of the support system due to the undervoltage, even without additional weighting the ceiling, achieve significantly greater improvement measures as simple beamed ceilings, so the requirements the increased sound insulation according to DIN 4109, Beibl. 2, fulfilled become. In addition, shocks are almost not more noticeable.

    Mit der erfindungsgemäßen Holzbalkendeckenanordnung lässt sich eine Sanierung vorhandener Holzbalkendecken ohne nennenswerte Unterbrechung der Wohnnutzung raumweise durchführen, wobei insbesondere die Nutzung des über der Holzbalkendecke liegenden Raumes nicht beeinträchtigt wird. Die Sanierung von der Unterseite, ohne Öffnung der Deckengefache erfolgt fast staubfrei, weil nach dem Einsetzen der selbst schneidenden Schrauben in die vorgebohrten Holzbohlen kein Bohrgut ausgetragen wird. With the wooden beam ceiling arrangement according to the invention leaves a renovation of existing wooden beamed ceilings without significant Interruption of housing use on a room-by-room basis, in particular, the use of the above the wooden beam ceiling lying room is not affected. The renovation from the bottom, without opening the ceiling drawer done almost dust-free, because after inserting itself no cutting screws in the pre-drilled wooden planks Cuttings are discharged.

    Durch die Holzbohlen und die federnd abgehängte Unterdecke wird die Raumhöhe nur um 7 bis 10 cm reduziert. Da typische sanierungsbedürftige Holzbalkendeckenanordnungen aber überwiegend in Altbauten mit ohnehin höheren Räumen vorzufinden sind, stellt die Reduzierung der Raumhöhe keine Einbuße des Raumeindrucks dar.Through the wooden planks and the springy suspended ceiling the room height is only reduced by 7 to 10 cm. As typical but in need of renovation wooden beam ceiling arrangements predominantly to find in old buildings with already higher rooms are the reduction of the ceiling height no loss of Space impression dar.
