Description
In der EP 1 152 087 A2 werden schallabsorbierende Elemente auf der Basis
von textilbewehrtem Beton beschrieben, bestehend aus einer oder mehreren
schallabsorbierenden Matten, die ohne verbleibenden Hohlraum in eine Betonschale
eingeschlossen sind, die größtenteils mit Textilbewehrung versehen
ist, wobei die Betonschale auf der Absorptionsseite mit Lochungen versehen
ist, durch die der Schall in die absorbierenden Matten eintreten kann, und wobei
die schallabsorbierenden Matten zumindest zu Bereichen der Betonschale
und relativ gleichmäßig über ihre Fläche verteilt, Verbindung zum Beton aufweisen,
die die Matten gegen Verschiebungen schützt.
Unter anderem, um diese Elemente hinreichend steif zu machen, weist die
dünne textilbewehrte Betonschale des schallabsorbierenden Elementes Rippenaufkantungen
auf.
Es hat sich gezeigt, daß die in der EP 1 152 087 A2 beschriebenen Elemente
bei leichter Ausführung mit einer sehr dünnen Betonschale nicht ausreichend
biegesteif sind. Das Vorhandensein einer Textilbewehrung und von Rippenaufkantungen
allein genügt also nicht, um die Betonschale sehr dünn und
damit auch sehr leicht auszuführen.
Darüberhinaus ist die Lage der Textilmatten im Beton nicht definiert und
gleichbleibend reproduzierbar.In
Among other things, in order to make these elements sufficiently rigid, the thin textile-reinforced concrete shell of the sound-absorbing element has rib edging.
It has been found that the elements described in
In addition, the position of the textile mats in the concrete is not defined and consistently reproducible.
Aufgabe der Erfindung ist es, ein einfaches, leichtes Lärmschutzelement aus Beton mit schallabsorbierender Füllung anzugeben, welches über eine hohe Formstabilität, Gleichmäßigkeit der Qualität und Dauerhaftigkeit verfügt.The object of the invention is to provide a simple, lightweight noise protection element Specify concrete with sound-absorbing filling, which has a high Dimensional stability, uniformity of quality and durability.
Die Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen
Merkmale gelöst.
Hierzu werden folgende Maßnahmen, bevorzugt in Kombination miteinander,
eingesetzt:
For this purpose, the following measures, preferably in combination, are used:
Darüber hinaus sieht die Erfindung in einer bevorzugten Ausgestaltung vor, daß die schallabgewandte Seite (2) eine strukturierte Oberfläche aufweist.Moreover, the invention provides in a preferred embodiment, that the sound side facing away from (2) has a textured surface.
Die textile Bewehrung besteht aus alkaliresistenten Fasern, bevorzugt alkaliresistenten
Glasfasern. Alternativ ist auch die Verwendung von Fasern möglich,
die nicht alkaliresistent sind, doch muß in diesem Falle ein nicht oder nur
wenig alkalisches Bindemittel als Matrix zum Einbetten verwendet werden.
In Querrichtung zu den Lärmschutzelementen werden die Fasern bevorzugt
nicht vorgespannt. Eine Vorspannung ist aber prinzipiell möglich. Die Querbewehrung
verläuft bevorzugt umlaufend in der Matrix.The textile reinforcement consists of alkali-resistant fibers, preferably alkali-resistant glass fibers. Alternatively, it is also possible to use fibers which are not alkali-resistant, but in this case a binder which is not or only slightly alkaline must be used as matrix for embedding.
In the transverse direction to the noise protection elements, the fibers are preferably not biased. A bias is possible in principle. The transverse reinforcement preferably runs circumferentially in the matrix.
Die Fig. 1 zeigt im Querschnitt den groben Aufbau eines erfindungsgemäßen Elementes, der Übersichtlichkeit halber ohne Darstellung der erfindungsgemäß wesentlichen darin befindlichen Bewehrung, deren Lage aber im folgenden beschrieben wird.Fig. 1 shows in cross section the rough structure of an inventive Element, for the sake of clarity without representation of the invention essential reinforcement therein, but their location in the following is described.
In einem bevorzugten Verfahren zur Herstellung wird ein Schaltisch mit Noppen-Matrize zur Herstellung der gelochten, schallzugewandten Seite (1) verwendet. Es werden dabei demontierbare Seitenschalungen eingesetzt, die über eine Profilierung für Nut und Feder (4) von Ober- und Unterseite des Lärmschutzelementes verfügen. Die Rand-/Stirnschalungen sind mit einer Vorrichtung zum Vorspannen der Längsbewehrung versehen.In a preferred method of manufacture, a baffle with nubbed die is used used to produce the perforated, sound-facing side (1). It demountable side molds are used, the via a profile for tongue and groove (4) from the top and bottom of the Noise protection element have. The edge / end formwork are with a Provided device for biasing the longitudinal reinforcement.
Im folgenden ist ausführlicher, aber nur beispielhaft, die Herstellung eines Lärmschutzelementes beschrieben, welches eine Länge von fünf Metern, eine Höhe von 66 Zentimetern und eine Dicke von 12 Zentimetern aufweist. Eine Lärmschutzwand wird durch Übereinandersetzen mehrerer solcher Elemente aufgebaut.The following is more detailed, but only by way of example, the production of a Noise protection element described, which has a length of five meters, a Height of 66 centimeters and a thickness of 12 centimeters. A Noise barrier is made by stacking several such elements built up.
Die Schalung ist vorab zu reinigen und mit Schalöl einzusprühen. The formwork must be cleaned in advance and sprayed with formwork oil.
Die Längs- und Querbewehrung ist vorab für ein Element zu fertigen. Die Querbewehrung wird auf Längsleisten montiert und aufgewickelt. Die Längsfäden sind vorab auf dem Spannrahmen gespannt und über Querleisten fixiert. Hierbei ist auf eine gleichmäßige Spannung der Fäden zu achten.The longitudinal and transverse reinforcement is to be prepared in advance for an element. The Transverse reinforcement is mounted on longitudinal strips and wound up. The longitudinal threads are preloaded on the clamping frame and fixed on cross bars. It is important to ensure a uniform tension of the threads.
In die vorbereitete Schalung wird die erste Lage Beton der Vorderseite (1) mit
ca. 3 mm Höhe eingebaut. Der Einbau erfolgt mit dem Dosiertrichter, so daß
ein Verschmutzen der Schalungsnoppen weitestgehend vermieden werden
kann.
Auf die erste Lage Beton der Vorderseite wird zuerst die Querbewehrung aufgelegt.
Hierbei werden die Längsleisten mittig über dem Element positioniert
und die Querbewehrung nach beiden Seiten gleichmäßig und unter leichter
Spannung über das Element abgewickelt.
Die für die Stege und Rückseite benötigte Querbewehrung verbleibt bis auf
weiteres auf den Längsleisten und wird neben der Schalung abgelegt.
Auf die Querbewehrung wird die Längsbewehrung aufgespannt. Über die beiden
Querleisten werden die Längsfäden unter leichter Vorspannung in der
Schalung fixiert. Die Endabschalelemente werden montiert.
Die zweite Lage Beton der Vorderseite (1) wird mit dem Dosiertrichter eingebaut.
Hierbei ist zu beachten, daß der Beton gleichmäßig in die Schalung
fließt und nach Einbau circa ein Millimeter der Schalungsnoppen aus dem
Beton hervorsteht. Hierdurch wird ein Verschluß der Absorptionslöcher (3) des
Lärmschutzelementes vermieden. Zum optimalen Verdichten des Betons
können die Tischrüttler eingeschaltet werden.
Vor dem Auflegen der Dämmplattenn (5) werden die Schalungsnoppen nochmals
mit einem Brett abgezogen, um eventuell vorhandene Betonreste zu
entfernen. Die Dämmplatten (5) werden auf die Noppen der Schalung aufgelegt
und seitlich mit einem Schaumstoffstreifen beklebt, um Schwindverformungen
des Elements beim Abbinden des Betons schadensfrei aufnehmen
zu können. Die Dämmplatten (5) sind in Längsrichtung auf Ober- und Unterseite
angefast. Um ein Aufschwimmen der Dämmplatten beim Einfüllen des
Betons der Seitenstege zu vermeiden, werden die Dämmplatten ballastiert.
Zur Montage der Seitenschalungsteile wird die Querbewehrung umgeschlagen
und anschließend seitlich neben der Schalung abgelegt. The first concrete layer of the front (1) with a height of approx. 3 mm is installed in the prepared formwork. The installation takes place with the metering funnel, so that contamination of the formwork knobs can be largely avoided.
On the first layer concrete of the front side, the transverse reinforcement is first applied. In this case, the longitudinal strips are positioned centrally above the element and the transverse reinforcement unwound on both sides evenly and with slight tension over the element.
The transverse reinforcement required for the webs and rear remains on the longitudinal ledges until further notice and is deposited next to the formwork.
On the transverse reinforcement, the longitudinal reinforcement is clamped. About the two transverse strips, the longitudinal threads are fixed under slight bias in the formwork. The Endabschalelemente be mounted.
The second concrete layer of the front (1) is installed with the hopper. It should be noted that the concrete flows evenly into the formwork and protrudes after installation about one millimeter of the formwork knobs out of the concrete. As a result, a closure of the absorption holes (3) of the noise protection element is avoided. For optimum compacting of the concrete, the table vibrators can be switched on.
Before laying the insulation boards (5) the formwork knobs are pulled off again with a board to remove any existing concrete residue. The insulation boards (5) are placed on the knobs of the formwork and laterally covered with a foam strip to absorb shrinkage deformation of the element when setting the concrete harmless. The insulation boards (5) are chamfered in the longitudinal direction on the top and bottom. In order to avoid floating of the insulation boards when filling the concrete of the side bars, the insulation boards are ballasted. To assemble the side moldings, the transverse reinforcement is folded over and then placed laterally next to the formwork.
Der Beton für die Seitenstege wird bis auf Oberkante der Dämmplatte eingefüllt.
Die ausreichende Befüllung der Seitenstege ist zu kontrollieren und gegebenenfalls
durch weitere Zugabe von Beton sicherzustellen.
Der Ballast auf den Dämmplatten (5) wird entfernt. Anschließend wird die erste
Lage Beton der Rückseite (2) auf die Dämmplatten (5) aufgebracht. Die
Längsbewehrung der Rückseite (2) wird in die Schalung eingespannt und fixiert.
Die Querbewehrung wird umgeschlagen und überlappend auf der Rückseite
(2) ausgelegt. Auf den Endabschalelementen werden Abziehleisten befestigt.
Der Einbau der letzten Betonlage der Rückseite (2) wird zeitnah, also bevorzugt
frisch in frisch, durchgeführt. Hierbei ist darauf zu achten, daß ausreichend
Beton eingefüllt wird, um Minderstärken des Betonquerschnitts zu vermeiden.
Abschließend erfolgt das Abziehen der Rückseite (2) des Lärmschutzelementes
und eine gewünschte Strukturierung mit Besenstrich oder Sandeinstreuung. The concrete for the side bars is filled up to the upper edge of the insulating board. The adequate filling of the side bars must be checked and, if necessary, ensured by further addition of concrete.
The ballast on the insulation boards (5) is removed. Subsequently, the first layer of concrete back (2) is applied to the insulation boards (5). The longitudinal reinforcement of the back (2) is clamped in the formwork and fixed. The transverse reinforcement is folded over and laid overlapping on the back (2). Abziehleisten are attached to the Endabschalelementen.
The installation of the last concrete layer of the back (2) is timely, so preferably fresh in fresh, carried out. Care must be taken to ensure that sufficient concrete is poured in to avoid reduced thickness of the concrete section.
Finally, the removal of the back (2) of the noise protection element and a desired structuring with brush stroke or Sandeinstreuung takes place.
