Description

Die Erfindung betrifft eine Sicht- und Lärmschutzwand mit Stützträgerkonstruktion, insbesondere für derartige Wände aus Beton und entsprechend hohem Gewicht.The invention relates to a visual and noise barrier with support structure, in particular for such walls made of concrete and correspondingly high weight.

Aufgabe der Erfindung ist die Schaffung einer Sicht- und Lärmschutzwand, bei der die eigentlichen Wandelemente und die Stützträgerkonstruktion aus voneinander unabhängigen Teilen bestehen und bei der die Wandelemente stirnseitig aneinanderstoßend angeordnet werden können und von den Stützträgern frei von jeder notwendigen Bodenauflage gehalten werden.The object of the invention is to provide a visual and noise barrier in which the actual wall elements and the support structure consist of mutually independent parts and in which the wall elements can be arranged abutting one another on the end face and are kept free of any necessary floor support by the support beams.

Demgemäß liegt die Erfindung darin, daß die Wandelemente mit einer Stützträgerkonstruktion kombiniert sind, deren einzelne Stützträger die Wandelemente an deren stirnseitigen Enden auf einer den unteren Rand der Wandelemente in praktisch der Gesamtdicke der Wandelemente diese untergreifenden Schulter tragen, wobei eine zwischen Schulter und Wandelement-Unterseite angeordnete, insbesondere formschlüssige Halterung gegen horizontale Versetzung vorgesehen ist, und daß die hochragenden Wandelemente in einer der Tiefe der Schulter entsprechenden Ausnehmung in der dem Wandelement zugewandten Seite des Stützträgers eingefügt und nahe ihrer Oberkante z. B. mittels Schrauben mit dem Stützträger verbunden sind, und daß jeweils zwei aneinanderstoßende stirnseitige Endbereiche der Wandelemente auf je einer Hälfte der Auflage-Schulter eines Stützträgers angeordnet sind.Accordingly, the invention resides in the fact that the wall elements are combined with a support beam construction, the individual support beams of which support the wall elements at their front ends on a lower edge of the wall elements in practically the total thickness of the wall elements, this shoulder, one between the shoulder and the wall element underside arranged, in particular positive mounting against horizontal displacement is provided, and that the towering wall elements inserted in a recess corresponding to the depth of the shoulder in the side of the support beam facing the wall element and near its upper edge z. B. are connected by means of screws to the support bracket, and that two abutting front end regions of the wall elements are each arranged on one half of the support shoulder of a support bracket are.

Durch eine sich zum jeweils oberen Ende verjüngende Form der Stützträger wird außer einer Materialersparnis eine geschmacklich gefällige schlanke Form des nach oben ragenden Bereichs der Stützträger erreicht.A shape of the support beams tapering toward the upper end in each case achieves a tasteful, slim form of the upwardly projecting region of the support beams in addition to saving material.

Die gemäß den Fign. 1 bis 3 aufgebaute Sicht- und Lärmschutzwand 1 besteht aus einzelnen Wandelementen 2 aus schwergewichtigem Beton. Dabei ist deren Vorderseite bzw. Frontseite 3 mit vergleichsweise spröden Schallschluckprofilen 4 belegt, welche von einer durchgehenden Betontragwand 5 mit hoher Tragfestigkeit getragen wird. Diese ist nahe ihrer Oberkante 6 z. B. mittels Schrauben 7 mit dem oberen, frei hochragenden Ende 8 des Stützträgers 9 verbunden. Die Verbindung mit dem Stützträger 9 erfolgt also an der dem Stützträger zugewandte Betontragwand 5 der Wandelemente 2.The according to FIGS. 1 to 3 built-up visual and noise protection wall 1 consists of individual wall elements 2 made of heavy-weight concrete. The front or front side 3 is covered with comparatively brittle sound absorption profiles 4, which is supported by a continuous concrete supporting wall 5 with a high load-bearing capacity. This is near its top edge 6 z. B. connected by means of screws 7 to the upper, freely projecting end 8 of the support beam 9. The connection with the support beam 9 thus takes place on the concrete support wall 5 of the wall elements 2 facing the support beam.

Dabei wirkt es anschauungsmäßig besonders vorteilhaft, wenn die obere Randbegrenzung 10 der Schallschutzelemente das obere Ende jedes Stützträgers überragt.It is illustratively particularly advantageous if the upper edge boundary 10 of the soundproofing elements projects beyond the upper end of each support beam.

Jeder Stützträger 9 hält jeweils zwei aneinanderstoßend stirnseitig und aneinanderstoßend angeordnete Enden 11 der Wandelemente, und zwar eingelagert in eine Ausnehmung 12 mit einer der Dicke der Wandelemente entsprechenden Tiefe. Dafür liegt die Unterkante 13 der Wandelemente auf einer Schulter 14 (ggf. mit Schutzelement 15) und ist dort mittels eines Stiftes 16 gegen Horizontalverschiebung fixiert.Each support bracket 9 holds two abutting ends 11 of the wall elements, which are arranged in a recess 12 with a depth corresponding to the thickness of the wall elements. For this purpose, the lower edge 13 of the wall elements lies on a shoulder 14 (possibly with a protective element 15) and is fixed there against horizontal displacement by means of a pin 16.

Der Stützträger 9 ist in einem Fundament 17 verankert und ragt auf der den Schallschluckprofilen 4 gegenüberliegenden Seite in möglichst schlanker Form mit einem Stützteil 18 hinter den Wandelementen zu deren oberen Rand hin hoch.The support beam 9 is in a foundation 17th anchored and protrudes on the side opposite the sound absorption profiles 4 in the slimmest possible form with a support part 18 behind the wall elements to the upper edge thereof.

Bei der in Fig. 6 dargestellten verbesserten Ausführungsform der Schallschluckprofile 4 sind zwischen der Betontragwand 5 aus Normalbeton und den Schallschluckprofilen 4 aus haufwerkporiger Magerbetonlage 4' gesonderte Hohlräume 20 vorgesehen, vorzugsweise mindestens teilweise in die Magerbetonlage 4' hineinragend, deren Wandungen bzw. Begrenzungen aus der Magerbetonlage und der Lage aus Normalbeton gebildet werden.In the improved embodiment of the sound-absorbing profiles 4 shown in FIG. 6, separate cavities 20 are provided between the concrete supporting wall 5 made of normal concrete and the sound-absorbing profiles 4 made of bulk porous lean concrete layer 4 ', preferably projecting at least partially into the lean concrete layer 4', the walls or boundaries of which Lean concrete layer and the layer of normal concrete are formed.

Diese sind vorzugsweise in den vertieft liegenden Bereichen der Schallschutzprofilierungen, z. B. den Wellentälern 43 angeordnet, und zwar mindestens einige davon.These are preferably in the recessed areas of the sound insulation profiles, e.g. B. the troughs 43, at least some of them.

Diese Hohlräume 20 verlaufen mit seitlich begrenzter Abmessung längs der Lärmschutzwand parallel hinter den Wellentälern 43 und sind zur verbesserten Schalldämmung mit Mineralwolle 21 gefüllt, die vorzugsweise in profilstrukturierter Form 44 vorliegt, damit Lufträume 45 nach dem Zugießen mit der Normalbetonlage 5 (Betontragwand) erhalten bleiben.These cavities 20 run with a laterally limited dimension along the noise protection wall parallel behind the wave troughs 43 and are filled with mineral wool 21, which is preferably in profile-structured form 44, for improved sound insulation so that air spaces 45 are preserved after pouring with the normal concrete layer 5 (concrete supporting wall).

Bei der Herstellung dieser Ausführungsform wird der Magerbeton in der Form zunächst bis zur Zwischenebene 46 gefüllt und verdichtet, d. h. unter Bildung der äußeren Schallschutzprofilierungen 47. Sodann werden zur Formgebung der Hohlräume 20 Latten bzw. Formprofile auf die Zwischenebene 46 aufgelegt und deren Zwischenräume weiter gefüllt und verdichtet, wobei die Innenseite der Formprofile in einer Ebene mit der Grenze zur Normalbetonlage liegt.In the manufacture of this embodiment, the lean concrete is first filled and compacted in the mold up to the intermediate level 46, i. H. to form the outer soundproofing profiles 47. Then, to shape the cavities, 20 slats or shaped profiles are placed on the intermediate level 46 and the spaces between them are further filled and compressed, the inside of the shaped profiles lying in a plane with the boundary to the normal concrete layer.

Nach kurzem Abbinden werden die Formprofile entnommen und in die entstehenden Hohlräume 20 die Füllung aus Mineralwolle 21 durch Nageln befestigt ehe das Einlegen der Armierungen und das weitere Vergießen mit der Normalbetonlage 5 erfolgt.After a brief setting, the shaped profiles are removed and the mineral wool filling 21 is fastened into the cavities 20 by nailing before the reinforcements are inserted and the further pouring with the normal concrete layer 5 takes place.

Die mit den Fig. 7 bis 11 dargestellte Lärmschutzwand-Konstruktion 1 unterscheidet sich von der in den Fig. 1 bis 5 beschriebenen vor allen Dingen dadurch, daß zwischen zwei Wandelementen 2 ein zurückgesetztes Wandelement 2' vorgesehen ist, um in einem damit gegebenen eingerückten Abschnitt 29 Zug-Bedienungsgeräte oder Zug-Signalzeichen aufstellen zu können.The illustrated with FIGS. 7 to 11 Noise barrier construction 1 differs from that described in FIGS. 1 to 5 above all in that a recessed wall element 2 'is provided between two wall elements 2 in order to set up 29 train operating devices or train signal signs in an indented section to be able to.

Dafür sind die Schultern 14 in doppelter Tiefe wie vergleichsweise in Fig. 4 ausgebildet, wobei die Schrauben 7 durch beide hintereinanderliegende Wandelemente 2 hindurchgehen (Fig. 9 oberer Abschnitt). Auf der (unteren) Aufsetzseite auf die Schulter 14 des Fußblocks 25 werden die Wandelemente 2 mittels einer Verdollung 24, d. h. vertikalen Stiften in Hülsen in Position gegen den Stützträger 9 gehalten, welcher zum Fundament 17 hin in einen verjüngten Zapfen 27 übergeht. Dieser Zapfen 27 ist in einer Ausnehmung 26 des Fundaments 17 fest verankert bzw. vergossen.For this purpose, the shoulders 14 are designed at twice the depth as comparatively in FIG. 4, the screws 7 passing through both wall elements 2 lying one behind the other (FIG. 9 upper section). On the (lower) placement side on the shoulder 14 of the foot block 25, the wall elements 2 are by means of a thickening 24, d. H. vertical pins in sleeves held in position against the support beam 9, which merges into a tapered pin 27 towards the foundation 17. This pin 27 is firmly anchored or cast in a recess 26 of the foundation 17.

In den Fig. 12 bis 14 wiedergegebene Stützträgerkonstruktion ist für beidseitig mit Schall-bzw. Lärmschutzprofilen besetzten, also im engen Zwischenraum zwischen zwei nebeneinanderliegenden Gleisen errichteten Schallschutzwänden vorgesehen.12 to 14 shown support structure is for both sides with sound or. Occupy noise protection profiles, i.e. provided in the narrow space between two adjacent soundproof walls.

Um die Enden 11 zweier derartiger Wandelemente 2 miteinander mit einer Stützkonstruktion im Sinne des Stützträgers 9 zu verbinden, ist eine Stützkonstruktion 30 vorgesehen, die beidseitig mit Schallschluckprofilen 4 besetzt ist, wodurch sich eine durchgehende Form der Profiloberfläche ergibt und deren Stützträger 9 bzw. deren Stützteil 18 die Betontragwand 5 für die Schallschluckprofile 4 bildet. Diese Stützträger 9 besitzen in Wandelement-Längsrichtung beidseitig die Schultern 14 auf denen die Enden 11 der Wandelemente 2 ruhen, und zwar positioniert mittels Verdollungen 24 aus in Hülsen geführten vertikalen Stiften.In order to connect the ends 11 of two such wall elements 2 to one another with a support structure in the sense of the support beam 9, a support structure 30 is provided which is covered on both sides with sound absorption profiles 4, which results in a continuous shape of the profile surface and its support beam 9 or its support part 18 forms the concrete supporting wall 5 for the sound absorption profiles 4. These support beams 9 have the shoulders 14 on both sides in the longitudinal direction of the wall element, on which the ends 11 of the wall elements 2 rest, and are positioned by means of bulges 24 made of vertical pins guided in sleeves.

Am oberen Ende der auf diese Weise mit Lärmschutzprofilen verkleideten Stützträger werden die Wandelemente mittels in Hülsen beweglichen, horizontal angeordneten Schiebedollen in Position gehalten, wobei die Verdollungen temperatur-dilatorische Bewegungen der Lärmschutzwand auffangen. Durch das stirnseitige Ansetzen zweier Lärmschutzelemente 2 seitlich gegen die Stützkonstruktion 30 ergeben sich auch zwei Ausgleichspalte mit geringerem Spaltabstand als nur ein einzelner Ausgleichsspalt.At the upper end of the support beams clad in this way with noise protection profiles Wall elements held in position by means of horizontally arranged sliding buckles that can move in sleeves, with the thickening absorbing temperature-dilatory movements of the noise protection wall. By attaching two noise protection elements 2 laterally against the support structure 30, there are also two equalizing gaps with a smaller gap spacing than just a single equalizing gap.

In dieser Ausführungsform der Lärmschutzwand 1 ist deren Oberkante gegen Eindringen von Feuchtigkeit mit einer kappenförmigen längsdurchgehenden Oberkantenabdeckung versehen.In this embodiment of the noise barrier 1, the top edge thereof is provided with a cap-shaped, longitudinally continuous top edge cover against the ingress of moisture.
