Abstract

The subject of the invention is a novel sound-insulating element which is capable of drawing heat off from its surrounds and rendering this usable for heating or service-water heating purposes in nearby buildings. This is achieved by closed ducts (1) which are integrated into the cladding of the elements, through which a liquid heat transfer medium passes and which are connected to one another via a distributing line (2) and a collecting line (3). The elements can be connected directly to one another, without costly additional installation, to form large-surface-area systems such as, for example, noise-insulating walls. <IMAGE>

Description

Flächiges SchallschutzelementFlat soundproofing element

Die Erfindung betrifft ein flächiges Schallschutzelement, bestehend aus einer selbsttragenden Konstruktion, einer vorderen schalldurchlässigen und einer rückwärtigen Verkleidung mit dazwischenliegender, schallabsorbierender Schicht.The invention relates to a flat soundproofing element, consisting from a self-supporting construction, a front sound-permeable and one rear cladding with a sound-absorbing layer in between.

Herkömmliche Schallschutzelementewerden, in der Regel zu einem System verbunden, dort eingesetzt, wo Menschen gegen Geräusche geschützt werden müssen, wie z.B. die Anlieger von Autobahnen gegen Verkehrslärm.Conventional soundproofing elements become, as a rule, a system connected, used where people need to be protected against noise, such as the residents of motorways against traffic noise.

Es sind zahlreiche Schallschutzelemente bekannt. Die meisten sind schallabsorbierend ausgerüstet, wobei das schallabsorbierende Material in der Regel durch eine beidseitige Verkleidung zum Beispiel gegen Verschmutzung geschützt werden muß. Aus derartigen Elementen zusammengefügte Lärmschutzwände erfordern einen hohen Investitionsaufwand.Numerous soundproofing elements are known. The most are Equipped sound-absorbing, the sound-absorbing material usually by a Cladding on both sides, for example against dirt must be protected. Require noise barriers assembled from such elements a high investment.

Aufgabe der Erfindung ist es, flächige Elemente für Lärmschutzwände zu entwicklen, die neben der Schallabsorbtion auch noch anderen technischen Zwecken dienen können, um so den Bau von Lärmschutzwänden wirtschaftlicher zu gestalten.The object of the invention is to provide flat elements for noise barriers to develop, in addition to sound absorption, also other technical purposes can serve to make the construction of noise barriers more economical.

Diese Aufgabe wird . erfindungsgemäß durch ein Schallschutzelement gelöst, das dadurch gekennzeichnet ist, daß die aus Metall oder Kunststoff bestehende Verkleidung des Elements zur Gewinnung von Wärme aus der Umwelt, aus Sonneneinstrahlung, Luft, Regen und dergleichen von einem flüssigen Wärmeträger durchströmt wird.This task will. according to the invention by a soundproofing element solved, which is characterized in that made of metal or plastic Cladding of the element to extract heat from the environment, from solar radiation, Air, rain and the like is flowed through by a liquid heat carrier.

Die so gewonnene Energie wird gegebenenfalls über einen Wärmepumpenkreislauf für die Raumheizung, Brauchwassererwärmung und dergleichen in nahegelegenen Gebäuden wie Wohnhäusern, Produktionsstätten und Treibhäusern verwandt.The energy obtained in this way is optionally used via a heat pump circuit for space heating, domestic water heating and the like in nearby buildings like residential houses, manufacturing plants and greenhouses.

Die Erfindung wird anhand der in Fig. 1 bis 4 dargestellten Ausführungsbeispiele näher erläutert, ohne sie hierdurch einzuschränken.The invention is based on the exemplary embodiments shown in FIGS explained in more detail without restricting it.

Bei der in Fig. 1 dargestellten Ausführungsform besteht die Verkleidung des Elements aus einem Trapezblech mit z.B. aufgeschweißter oder aufgelöteter Rohrleitung (1), durch die der flüssige Wärmeträger, beispielsweise eine Sole, strömt.In the embodiment shown in Fig. 1, the cladding is made of the element made of a trapezoidal sheet with e.g. welded or soldered pipe (1), through which the liquid heat transfer medium, for example a brine, flows.

In Fig. 2 ist eine Verblendung aus stranggepreßten Profilen mit integrierten Strömungskanälen (1) dargestellt, durch die der flüssige Wärmeträger, z.B. eine wäßrige Athylenglykollösung, fließt.In Fig. 2 is a facing made of extruded profiles with integrated Flow channels (1) shown through which the liquid heat transfer medium, e.g. a aqueous ethylene glycol solution flows.

Die Strömungskanäler.bzw. Rohrleitungen (1) können sowohl auf der vorderen wie auf der rückwärtlgen Verkleidung der Elemente angeordnet sein, oder auch auf beiden Seiten.The flow channels. Pipelines (1) can both on the be arranged on the front as well as on the rear paneling of the elements, or also on both sides.

Sie können waagerecht, senkrecht oder geneigt verläufen.They can run horizontally, vertically or at an angle.

Sie sind in einere besonderen Ausführungsform, wie in Fig. 3 dargestellt, an den Enden über eine Verteiler-(2) und eine Sammelleitung (3) miteinander verbunden.They are in a particular embodiment, as shown in Fig. 3, connected to each other at the ends via a distributor line (2) and a collecting line (3).

Aber es ist ebenso möglich, die Wärme Uber ein beispielsweise mäanderartig verlegtes Einzelrohr abzuführen.But it is also possible to use the heat in a meandering manner, for example lead away laid single pipe.

Beim Zusammenbau mehrerer, in Fig. 3 dargestellter Elemente, können die Leitungen (2) und (3) mit denen der Nachbarelemente direkt ohne aufwendige, zusätzliche Installation zu einem System verschaltet werden, wie beispielhaft in Fig. 4 gezeigt. Vor-(4) und RUcklauf (5) der Wärmeträgerleitung werden am untersten Element absperrbar angeschlossen.When assembling several, shown in Fig. 3 elements, can the lines (2) and (3) with those of the neighboring elements directly without complex, additional installation can be interconnected to form a system, as exemplified in Fig. 4 shown. The flow (4) and return (5) of the heat transfer line are at the bottom Lockable element connected.

Auf dem obersten Element sind automatische Be- und Enlüftungsventile (6) auf der Verteiler-(2) bzw. Sammelleitung (3) angeordnet. Die mit der Sammelleitung (3) verbundene Leitung (7) ermöglicht die Verschaltung der Elemente nach Tichelmann und damit gleiche Druckverhältnisse innerhalb der einzelnen im System verbundenen Elemente.On the top element there are automatic ventilation and exhaust valves (6) arranged on the distributor (2) or collecting line (3). The one with the manifold (3) connected line (7) enables the interconnection of the elements according to Tichelmann and thus the same pressure conditions within the individual connected in the system Elements.
