Abstract

The suspension and the retainers for the damper mass (2) is by means of rigid guides, of which those (3) for suspension are length stable, and those (6) for retention are elastically pliable in their ability to alter in length. The latter are formed telescopically. All the guides are approximately of the same length. In the rest position of the damper mass (2), the guides (3,6) enclose with the structure longitudinal axis an angle of approximately 15-25 deg., and are equally distributed over the periphery of the structure (1). At their link points, the guides are enclosed by folding bellows, and those for retention (6) are formed by elastomer springs. USE/ADVANTAGE - Damper to protect slim structures, such as chimneys, from vibrations.

Description

Die Erfindung betrifft einen Schwingungstilger für schlanke Bauwerke, insb. Schornsteine, mit pendelnd aufgehängter, konzentrisch zum Bauwerk angeordneter, ggfs. aus Einzelelementen bestehender Tilgermasse, die durch mehrere am Bauwerk befestigte Halterungen in ihren Bewegungen begrenzt ist, die unterhalb der Tilgermasse mit dem Bauwerk in Verbindung stehen.The invention relates to a vibration damper for slim structures, especially chimneys, with swinging suspended, arranged concentrically to the building, if necessary, from individual elements existing absorber mass, the through several brackets attached to the structure is limited in their movements, which is below the Absorb mass in connection with the structure.

Bei bekannten Tilgern dieser Art wird sowohl die Aufhängung als auch die Halterung von Seilen gebildet. Wenngleich auch eine solche Ausführung vergleichsweise einfach ist in Bezug auf die Befestigung der Tilger­ masse, so können sich aufgrund der unbedingt erfor­ derlichen Einspannung der Seilenden Schwierigkei­ ten ergeben, weil das stark biegsame Element Seil durch starre Elemente eingefaßt werden muß. In known absorbers of this type, both the Suspension formed as well as the holder of ropes. Even if such a design is comparatively is simple in terms of attaching the absorber mass, because of the absolutely necessary of the rope ends difficulty ten result because of the highly flexible element rope must be enclosed by rigid elements.  

Darüber hinaus ist es bekannt zur pendelnden Aufhängung der Tilgermasse längenveränderbare Pendel zu benutzen; eine zusätzliche Halterung der Tilgermasse, deren Elemente unterhalb der Tilgermasse mit dem Bauwerk ver­ bunden ist, findet hierbei keine Anwendung (DE-OS 25 51 471).It is also known for swinging suspension to use the pendulum, which is adjustable in length, of the absorber mass; an additional holder of the absorber mass, whose Ver elements below the absorber mass with the building is bound, does not apply here (DE-OS 25 51 471).

Der Erfindung liegt die Aufgabe zugrunde, die eingangs erwähnten Schwingungstilger so auszuführen, daß eine lange, wartungsfreie Betriebszeit des Schwingungs­ tilgers erreichbar und eine ausreichend sichere Be­ festigung der die Tilgermasse tragenden Elemente mög­ lich ist.The invention is based on the object Execute mentioned vibration damper so that a long, maintenance-free operating time of the vibration tilgers reachable and a sufficiently safe loading consolidation of the elements supporting the absorber mass possible is.

Zur Lösung dieser Aufgabe wird erfindungsgemäß sowohl die Aufhängung als auch die Halterung durch biegesteife Lenker erreicht, von denen die Lenker der Aufhängung längenstabil und die Lenker der Halterung elastisch nachgiebig längenveränderbar sind. Dabei können für die Lenker der Halterung Teleskopdämpfer oder ähnliche Elemente benutzt werden.To solve this problem, both the suspension as well as the bracket by rigid Handlebars reached, of which the handlebars of the suspension stable in length and the handlebars of the bracket elastic are resiliently variable in length. You can do this for the handlebars of the mount telescopic damper or the like Elements are used.

Bei einem so ausgeführten Schwingungstilger werden für die oberen und die unteren Lenkerenden stabile Gelenke benutzt, die die Verschwenkbewegungen der Lenker zulassen, während die Dämpfung durch die Lenker der Halterung, also die sich nach unten erstreckenden Lenker herbeigeführt wird.With a vibration damper executed in this way, for the upper and lower handlebar ends use stable joints, which allow the pivoting movements of the handlebars while the damping through the handlebars of the bracket, so the downwardly extending handlebars becomes.

Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführungsbeispiel der Erfindung dargestellt ist.Further details of the invention are based on Drawing explained, in which an embodiment of the Invention is shown.

Die Abbildung zeigt einen senkrechten Teilschnitt durch den Kopf eines schlanken Schornsteins.The illustration shows a partial vertical section through the head of a slim chimney.

Der Schornstein 1 wird von einem Stahlrohr gebildet; konzentrisch zum Schornstein 1 ist die ringförmige Tilgermasse 2 des Schwingungstilgers für das obere Ende des Schornsteins 1 angeordnet.The chimney 1 is formed by a steel pipe; concentrically to the chimney 1, the annular absorber mass of the vibration absorber 2 is arranged for the upper end of the chimney. 1

Am freien Ende des Schornsteins 1 ist dieser außen mit drei oder mehreren, gleichmäßig über den zylindrischen Schornstein 1 verteilt angeordneten und dort angeschweiß­ ten Lagerstellen für biegesteife, längenstabile Len­ ker 3 versehen; die Gelenke sind mit 4 bezeichnet. Die unteren Enden der Lenker 3 greifen ihrerseits gelenkig an der Oberseite der Tilgermasse 2 an, die dazu mit Gelenkstellen 5 ausgestattet ist, um so eine pendelnde Aufhängung der Tilgermasse 2 am Schornstein 1 zu erreichen, die bei Ausschlägen ihre konzentrische Stellung zum Schornstein 1 verläßt und dementsprechend eine exzentrische Lage einnehmen kann. Um dabei die gewünschte Schwingungstilgung zu erreichen, ist die Tilgermasse 2 über sich nach unten erstreckende, weitere Lenker 6 mit dem Schornstein 1 verbunden, der deshalb angeschweißte Lagerstellen 7 aufweist, um die Gelenk­ stellen 8 bilden zu können, während die Tilgermasse 2 am unteren Rand Gelenkstellen 9 erhalten hat, um dort die Lenker 6 angreifen zu lassen, die zwar ebenfalls biegesteif sind, jedoch als gegen eine Rückstellkraft längenveränderbare Teleskopdämpfer ausgeführt sind, bei denen vorzugsweise eigengedämpfte Federn im Inneren benutzt werden sollen, aber auch hydraulische Elemente zur Dämpfung benutzt werden können. At the free end of the chimney 1 , this is provided on the outside with three or more, evenly distributed over the cylindrical chimney 1 and welded there th bearing points for rigid, length-stable Len ker 3 ; the joints are labeled 4 . The lower ends of the handlebars 3 in turn jointly engage the top of the absorber mass 2 , which is equipped with articulation points 5 in order to achieve a pendulum suspension of the absorber mass 2 on the chimney 1 , which leaves its concentric position with chimneys 1 and rashes accordingly can assume an eccentric position. In order to achieve the desired vibration damping, the absorber mass 2 is connected to the chimney 1 via downwardly extending further links 6 , which therefore has welded-on bearing points 7 in order to be able to form the articulation 8 , while the absorber mass 2 is at the bottom Has received hinge points 9 to allow the handlebars 6 to attack there, which are also rigid, but are designed as telescopic dampers that are variable in length against a restoring force, in which self-damped springs should preferably be used in the interior, but also hydraulic elements can be used for damping .

Angesichts der Längenveränderbarkeit der Lenker 6 und der gelenkigen Befestigung der Lenkerenden sind die gewünschten Ausschläge der Tilgermasse 2 in Bezug auf den Schornstein 1 möglich.In view of the variability in length of the handlebars 6 and the articulated fastening of the handlebar ends, the desired deflections of the absorber mass 2 in relation to the chimney 1 are possible.

Vorzugsweise werden die Lenker 3, 6 so ausgeführt, daß sie im wesentlichen die gleiche Länge haben, zudem sollen sie so bemessen und angeordnet sein, daß sie bei etwa symmetrischer Anordnung in Bezug auf die Tilgermasse 2 mit der Senkrechten bzw. der Längsachse des Schornsteins Winkel von etwa 15-25° ein­ schließen. Dieser Winkel ist mit a bezeichnet.Preferably, the handlebars 3 , 6 are designed so that they have substantially the same length, and they should be dimensioned and arranged so that they are at an approximately symmetrical arrangement with respect to the absorber mass 2 with the vertical or the longitudinal axis of the chimney angle of about 15-25 degrees. This angle is labeled a.

Ferner können zum Schutz der Gelenkstellen die bei 10 angedeuteten Faltenbälge vorgesehen werden. Auch kann der Schornstein 1 außen in Höhe der Tilgermasse 2 oder diese an ihrer Innenseite mit Anschlagpuffern ausgestattet werden, um ein elastisches Abfangen der Tilgermasse bei zu großen Ausschlägen abfangen zu können. Weiterhin kann der Schwingungs­ tilger teilweise oder insgesamt gegen Witterungs­ einflüsse abgedeckt sein.Furthermore, the bellows indicated at 10 can be provided to protect the articulation points. The chimney 1 can also be equipped on the outside at the level of the absorber mass 2 or on the inside thereof with stop buffers in order to be able to intercept an elastic interception of the absorber mass in the event of excessive deflections. Furthermore, the vibration absorber can be partially or totally covered against weather influences.

Es sei noch darauf hingewiesen, daß die Lenker 3, 6 vor­ zugsweise so angeordnet werden, daß sie (bei Betrachtung des Schornstein von der Seite her) in Längsrichtung des Schornsteins, also senkrecht verlaufen; ins. sollen dabei übereinanderliegende, benachbarte Lenker zumindest in etwa fluchten.It should also be noted that the handlebars 3 , 6 are preferably arranged in such a way that they (when the chimney is viewed from the side) run in the longitudinal direction of the chimney, ie vertically; ins. At the same time, adjacent links should be at least approximately aligned.
