Bogenförmiges Lärmschutzwandelement aus Stahlbeton mit eirr:r schallschluckenden VorsatzschaleArched noise barrier element made of reinforced concrete with a sound-absorbing facing
Die Erfindung betrefft «in bogenförmiges Lärmschutzwandelement aus Stahlbeton mit einer schallschluckenden Vorsatzschale aus haufwerksporigem Beton, wobei zusätzlich die Vorsatzschale durch senkrecht verlaufende Rippen profiliert ist.The invention relates to an arched noise barrier element made of reinforced concrete with a sound-absorbing facing shell made of porous concrete, whereby the facing shell is additionally profiled by vertical ribs .
Bisher existieren Lärmschutzwandelemente mit einer Tragschale aus Stahlbeton und einer Vorsatzschale aus häufwerksparigern Beton in verschiedenen Varianten, z. B. als ebene Tragschale mit ebenen und glatten Vorsatzschalen, als ebene Tragschalen mit ebenen und profilierten (gerippten) Vorsatzschalen, und als bogenförmige Tragschalen mit ebenfalls gekrümmten aber glatten Vorsatzschalen.To date, noise barrier elements with a supporting shell made of reinforced concrete and a facing shell made of aggregate concrete exist in various variants, e.g. as a flat supporting shell with flat and smooth facing shells, as flat supporting shells with flat and profiled (ribbed) facing shells, and as arched supporting shells with also curved but smooth facing shells.
Die beiden primären Anforderungen an eine absorbierende Lärmschutzwand hinsichtlich Standsicherheit und Schallabsorption werden dabei durch Tragschale bzw. schallschluckende Vorsatzschale erfüllt, wobei durch eine Profilierung der Vorsatzschale z. B. in Form von senkrecht verlaufenden Rippen und der damit verbundenen Vergrößerung der absorbierenden Oberfläche eine Verbesserung hinsichtlich des Lärmschutzes erzielt wird.The two primary requirements for an absorbent noise barrier in terms of stability and sound absorption are met by the supporting shell or the sound-absorbing facing shell, whereby an improvement in terms of noise protection is achieved by profiling the facing shell, e.g. in the form of vertical ribs and the associated enlargement of the absorbent surface.
Die Aufgabe der Erfindung besteht nun darin, auch im Bereich von bogenförmigen Lärmschutzwandelementen durch Ausbildung einer mit Rippen versehenen Vorsatz-The object of the invention is to provide a ribbed front section in the area of arched noise barrier elements.
schale die Schallabsorption zu verbessern. Dabei sollte das sich als günstig erwiesene Herstellungsverfahren beibehalten werden, wonach - wie aus Fig. 1 \ bzw. Fig. 2 ersichtlich - die Elemente "liegend" hergestellt werden, wobei die % Vorsatzschale (1) zuerst auf die Schalung (2) aufgebracht und die Tragschaleshell to improve sound absorption. The manufacturing process that has proven to be advantageous should be retained, whereby - as can be seen from Fig. 1 and Fig. 2 - the elements are manufactured "lying", whereby the % facing shell (1) is first placed on the formwork (2) and the supporting shell
(3) direkt auf den noch frischen Porenbeton betoniert werden kann.(3) concrete can be poured directly onto the still fresh aerated concrete.
&psgr; Eine herstellungstechnisch sinnvolle und machbare Lösung der Aufgabe wird &psgr; A technically reasonable and feasible solution to the problem is
% durch die Erfindung auf zweierlei Weise ermöglicht, wobei für die Herstellung entscheidend ist, daß die Seitenflächen der Rippen beim Ausschalen (Hochheben des Elements aus der Schalung) auf der Schalung gleiten können or.ne zu verkanten. Dies wird zum eiuen - wie in Fig. 1 dargestellt - dadurch ermöglicht, daß der Winkel (5), den die Seitenflächen jeder Rippe (4) miteinander einschließen und der die Konizität der Rippen ausmacht, mindestens zweimal so groß ist wie der Winkel (6) zwischen der Tangente an die Achse des bogenförmigen Elements und der zwischen den Bogenenden spannenden Sehne. Somit kann sich das Element beim Hochheben nie in der Schalung verkanten, weil der dafür maßgebende Winkel (7) ziwschen Rippe und Vertikalen ungünstigstenfalls zu Null wird. % is made possible by the invention in two ways, whereby it is crucial for production that the side surfaces of the ribs can slide on the formwork during stripping (lifting the element out of the formwork) without becoming jammed. This is made possible - as shown in Fig. 1 - by the fact that the angle (5) that the side surfaces of each rib (4) form with each other and which constitutes the conicity of the ribs is at least twice as large as the angle (6) between the tangent to the axis of the arched element and the chord spanning between the ends of the arch. Thus the element can never become jammed in the formwork when lifted because the decisive angle (7) between the rib and the vertical becomes zero in the worst case scenario.
Aus der Fig. 2 geht die zweite Möglichkeit hervor, wobei die horizontalen Achsen (8) der vertikal verlaufenden Rippen (4) näherungsweise parallel angeordnet sind.The second possibility is shown in Fig. 2, where the horizontal axes (8) of the vertically extending ribs (4) are arranged approximately parallel.
