Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Halterung von Führungsschienen für Personen- und Lastenaufzüge, die zur Verbindung der Führungsschiene mit einer gebäudeseitigen Schachtwandung ein beispielsweise zweigeteiltes, an der Führungsschiene festgelegtes Winkelprofil und einem mit diesem und der Schachtwandung verbindbares Gegenprofil aufweist, wobei zwischen dem Winkelprofil und dem Gegenprofil ein Isolator aus einem Elastomer angeordnet ist.The invention relates to a device for mounting guide rails for passenger and goods lifts, which has for connection of the guide rail with a building-side shaft wall, for example, a two-part, fixed to the guide rail angle profile and connectable to this and the shaft wall counter profile, wherein between the angle section and the counter profile is an insulator made of an elastomer.

Vorrichtungen zur Halterung von Führungsschienen für Personen- und Lastenaufzüge dienen insbesondere dazu, die Führungsschiene sicher zu halten. Diese haben die einschlägigen Normen für Aufzüge zu erfüllen, die auch dazu dienen, die Verformung der Führungsschiene während des Aufzugbetriebes zu begrenzen, damit der Fahrkorb eines Aufzuges oder das Gegengewicht ihre Fahrbahn nicht verlassen können und sicherstellen, dass vorhandene Sicherheitseinrichtungen wie beispielsweise Fangvorrichtungen ihre Funktion erfüllen können. Dokument D1 offenbart eine Vorrichtung zur Halterung von Führungsschienen für Personen- und Lastenaufzuge zeigt, die zur Verbindung der Führungsschiene mit einer gebäudeseitigen Schachtwandung ein beispielsweise zweiteiliges, an der Führungsschiene festlegbares Winkelprofil und ein mit diesem an der Schachtwandung verbindbares Gegenprofil aufweist. Weiter offenbart es auch, das zwischen dem Winkelprofil und dem Gegenprofil ein Isolator aus einem Elastomer angeordnet ist. Bei der Bewegung des Fahrkorbs durch den Aufzugsschacht entstehen an den verschiedensten Stellen Körperschalleinträge, d.h. so genannte Stöße, die in die Schachtwand abgeleitet werden. Ein besonderer Einfluss hat hier die Montagequalität der Schienenstränge und des Schienenstoßes, die über dieses größer oder geringer ausfallen können. Derzeit bekannte Vorrichtungen der eingangs genannten Art sollen der Geräuschentwicklung durch die Zwischenlager eines elastischen Kunststoffes wie z.B. Polyurethan (Elastomer) entgegenwirken. Derzeit sind solche körperschallisolierte Vorrichtungen mit einer zwischen dem Gegenprofil und dem Winkelprofil angeordneten Isolatorschicht versehen. Solche Vorrichtungen geben jedoch einen derartigen Stoß als Beschleunigungsspitze über die Isolatorschicht und das Gegenprofil an die Schachtwandung weiter.Devices for holding guide rails for passenger and goods lifts serve in particular to keep the guide rail safely. These have to meet the relevant standards for lifts, which also serve to limit the deformation of the guide rail during elevator operation, so that the car of a lift or the counterweight can not leave their lane and ensure that existing safety devices such as safety gear perform their function can. Document D1 discloses a device for holding guide rails for passenger and freight hoists shows that for connecting the guide rail with a building-side shaft wall has, for example, a two-part, fixable to the guide rail angle profile and connectable to this on the shaft wall counter profile. Furthermore, it also discloses that an insulator made of an elastomer is arranged between the angle profile and the counterprofile. During the movement of the elevator car through the elevator shaft, body sound recordings, ie so-called impacts, which are diverted into the shaft wall, occur at the most varied points. A special influence here has the assembly quality of the rail tracks and the rail joint, which can be greater or less over this. Currently known devices of the aforementioned Art should counteract the noise development through the intermediate storage of an elastic plastic such as polyurethane (elastomer). Currently, such structure-borne sound insulated devices are provided with an insulator layer arranged between the counter profile and the angle profile. However, such devices give such a shock as acceleration peak on the insulator layer and the mating profile to the shaft wall further.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Vorrichtung zur Halterung für Führungsschienen für Personen- und Lastenaufzüge zu schaffen, die derart körperschallisoliert ausgerüstet ist, dass auch beim Überfahren eines Schienenstoßes eine weitere Geräuschreduzierung möglich ist.It is therefore an object of the present invention to provide a device for mounting guide rails for passenger and goods lifts, which is equipped with a structure-borne sound insulation, that even when driving over a rail joint a further noise reduction is possible.

Zur Lösung dieser Aufgabe zeichnet sich die Vorrichtung der eingangs genannten Art dadurch aus, dass der Isolator aus zwei mit Abstand zueinander angeordneten Isolatorschichten besteht und zwischen den beiden Isolatorschichten ein metallisches Ausgleichsmasseteil angeordnet ist.To solve this problem, the device of the type mentioned is characterized in that the insulator consists of two spaced-apart insulator layers and between the two insulator layers, a metallic Ausgleichsmasseteil is arranged.

Damit ist eine Vorrichtung zur Halterung von Führungsschienen für Personen- und Lastenaufzüge geschaffen, bei der eine wesentliche Verbesserung der Körperschallisolierung dadurch erreicht wird, dass der Schall zunächst durch eine erste Isolatorschicht auf eine Ausgleichsmasse übertragen wird, wobei das Schallspitzen abgebaut werden. Die Ausgleichsmasse überträgt eine solche bei Überfahren eines Stoßes erzeugte Beschleunigungsspitze des Schalls über eine zweite Isolatorschicht an die Schachtwandung. Spitzengeräusche die bei bewegtem Fahrkorb erzeugt werden, insbesondere wenn der Fahrkorb und /oder ein Gegengewicht z.B. über einen nicht absolut einwandfrei hergestellten Führungsschienenstoß fahren, können daher bei der erfindungsgemäßen Vorrichtung wesentlich besser gedämpft werden, was zu einer wesentlichen Geräuschminderung bei einem Aufzugbetrieb beiträgt.Thus, a device for holding guide rails for passenger and goods lifts is created, in which a substantial improvement of structure-borne sound isolation is achieved in that the sound is first transmitted through a first insulator layer on a balancing mass, the sound peaks are reduced. The balancing mass transmits such an acceleration peak of the sound generated when a shock is passed over a second insulator layer to the shaft wall. Top noise generated when the car is moving, In particular, when the car and / or a counterweight drive, for example, over a not absolutely perfectly manufactured guide rail shock can therefore be significantly better damped in the inventive device, which contributes to a significant noise reduction in a lift operation.

Bevorzugtermaßen werden Isolatorschichten mit unterschiedlichen Eigenschaften verwendet, insbesondere bezüglich ihrer Steifigkeit im Hinblick auf ihre Elastizität. Durch die Verwendung von zwei unterschiedlichen Isolatorschichten und der Ausgleichsmasse wird ein Teil der Energie des Schallimpulses zunächst in diesem dadurch gebildeten Federmassesystems zwischengespeichert, wodurch die Höhe der zur Verfügung stehenden Energie zur Erzeugung einer Geräuschspitze reduziert wird. Dadurch ist das System insgesamt leiser.Preferably, insulating layers with different properties are used, in particular with respect to their stiffness with regard to their elasticity. By using two different insulator layers and the balancing mass, a portion of the energy of the sonic pulse is first stored temporarily in this spring mass system formed thereby, whereby the amount of energy available for generating a noise peak is reduced. This makes the system quieter overall.

Das Ausgleichsmasseteil kann den zur Verfügung stehenden Platzverhältnissen angepasst werden. Um die Größe der Ausgleichsmasse zu erhöhen, insbesondere dann, wenn der Raum zwischen Isolatorschichten relativ eng sein sollte, kann das Ausgleichsmasseteil derart gestaltet sein, dass es Isolatorschichten unten und/oder oben und/oder seitlich überragt.The leveling compound can be adapted to the available space. In order to increase the size of the balancing mass, in particular when the space between insulator layers should be relatively narrow, the balancing mass portion may be designed such that it projects beyond insulator layers below and / or above and / or laterally.

Um darüber hinaus noch dem entgegengewirkt zu halten, Sorge dagegen zu tragen, dass sich etwaige Setzerscheinungen oder Alterungsprozesse der Isolatorschichten aus dem Elastomer negativ bemerkbar machen, kann darüber hinaus vorgesehen sein, dass an dem Winkelprofil, dem Gegenprofil und/oder der Schachtwandung Anschläge als Widerlager für die Isolatorschichten zur Begrenzung einer Ausdehnungsbewegung auf die Schachtwandung zu oder von dieser weg vorgesehen sind, wobei zumindest zwischen dem Widerlager und der Isolatorschicht zumindest bei Erstmontage der Isolatorschichten ein Spalt ausgebildet ist. Bei einer derartigen Vorrichtung können Ausdehnungsbewegungen der Isolatorschicht nach Durchlaufen des vorgesehenen Spaltes begrenzt werden. Dadurch sind maximale Verformungen der Führungsschiene zu begrenzen und somit sind nach den einschlägigen Aufzugsnormen vorgeschriebenen Verformungen einzuhalten. Aufgrund des Spaltmaßes ist sicher zu stellen, dass eine Elastomer als Körperschallisolatoren aufgrund ihrer Nachgiebigkeit beim Anziehen von Befestigungsschrauben vorzuspannen sind, um die beschriebenen Geräusche nachhaltig zu verringern. Kommen Alterungs- und Setzvorgänge dazu, greifen die Anschläge als Widerlager ein und begrenzen die Summe von Verformungen von Schienenbefestigung und Schiene.Moreover, in order to counteract this, to prevent concern that any settling or aging processes of the insulator layers made of the elastomer make negative noticeable, can also be provided that at the angle profile, the counter-profile and / or the shaft walls attacks as abutment for the insulator layers for limiting an expansion movement are provided on the shaft wall to or from this away, wherein at least between the abutment and the insulator layer, at least during initial assembly of the insulator layers, a gap is formed. In such a device expansion movements of the insulator layer can be limited after passing through the intended gap. As a result, maximum deformations of the guide rail are to be limited and thus according to the relevant elevator standards prescribed deformations must be observed. Due to the gap size is to ensure that an elastomer as a structure-borne sound insulators are to be biased due to their flexibility when tightening screws to sustainably reduce the noise described. If aging and setting processes occur, the stops act as an abutment and limit the sum of rail fastening and rail deformation.

Die Anschläge können an dem Winkelprofil, aber auch an Schachtwänden so vorgesehen sein, dass sie unter Ausbildung des Spaltmaßes Ausdehnungsbewegungen in horizontalen Ebenen begrenzen. Ebenfalls ist es möglich, sei es alternativ, oder kumulativ, Anschläge als Widerlager an einem Gegenprofil auszubilden. Ebenfalls ist es möglich, z.B. oberhalb oder unterhalb der Isolatorschichten Anschläge vorzusehen, um eine Ausdehnung in vertikaler Richtung zu begrenzen.The stops may be provided on the angle profile, but also on shaft walls so that they define expansion movements in horizontal planes while forming the gap dimension. It is also possible, alternatively or cumulatively, to form stops as an abutment on a counter-profile. It is also possible, e.g. Provide stops above or below the insulator layers to limit expansion in the vertical direction.

In der Zeichnung sind grundsätzlich übereinstimmende Teile mit übereinstimmenden Bezugsziffern versehen. Allgemein mit 1 ist die Vorrichtung zur Halterung einer Führungsschiene 2 für Personen- und Lastenaufzüge beziffert. Diese ist an einer gebäudeseitigen Schachtwandung 3 in einer Halterungsschiene 4 über Befestigungsschrauben 5 festzulegen. Die Führungsschiene 2 ihrerseits ist über Klammerhalter 6 an der Vorrichtung befestigt.In the drawing, basically matching parts are provided with matching reference numerals. 1, the device for holding a guide rail 2 for passenger and goods lifts is numbered. This is to be fixed on a building-side shaft wall 3 in a mounting rail 4 via mounting screws 5. The guide rail 2 in turn is attached via bracket holder 6 to the device.

Die Vorrichtung 1 hat ein zweiteiliges Winkelprofil 7 und ein Gegenprofil 9. Das Winkelprofil 7 besteht aus zwei metallischen L-förmigen Einzelprofilen 7.1 und 7.2, die über Befestigungsschrauben 8 aneinander festgelegt sind. Um Geräusch- und Geräuschspitzen zu dämmen, sind zwischen dem Winkelprofilteil 7.2 des Winkelprofils 7 und dem Gegenprofil 9 zwei Isolatorschichten 10 vorgesehen, die einen Abstand zueinander aufweisen. Dieser Abstand wird ausgefüllt durch ein metallisches Ausgleichsmassenteil 11. Die Isolatorschichten 10 können hinsichtlich ihrer Steifigkeit in Bezug auf ihre Elastizität unterschiedliche Eigenschaften aufweisen.The device 1 has a two-part angle section 7 and a counter-profile 9. The angle section 7 consists of two metallic L-shaped individual sections 7.1 and 7.2, which are fixed by fastening screws 8 to each other. In order to dampen noise and noise peaks, two insulator layers 10 are provided between the angle section part 7.2 of the angle section 7 and the counter-profile 9, which are at a distance to each other. This distance is filled by a metallic leveling compound part 11. The insulator layers 10 may have different properties in terms of their stiffness with respect to their elasticity.

Die Befestigungsschraube 5 ist in eine Kunststoffbuchse 12 eingesetzt, die die Isolatorschichten 10, das Ausgleichsmasseteil 11, das Winkelprofilteil 7.2 und des Gegenprofil 9 durchsetzen. Diese Kunststoffbuchse hat einen Kragen 13, in dem ein weiteres ringförmiges metallisches Ausgleichsmassenteil 14 eingesetzt ist.The fastening screw 5 is inserted into a plastic bushing 12, which pass through the insulator layers 10, the compensating mass part 11, the angle profile part 7.2 and the counter-profile 9. This plastic bushing has a collar 13, in which a further annular metallic compensation mass part 14 is inserted.

In dem Ausführungsbeispiel nach Fig. 3 hat das Gegenprofil 9 eine im wesentlichen im Querschnitt U-förmige Gestalt mit abgewinkelten aufeinander zustehenden Endbereichen der Seitenschenkel 9.1. Diese abgewinkelten Enden umgreifen das ebenfalls bereichsweise U-förmig ausgebildete Winkelprofilteil 7.2, das seinerseits die beiden Isolatoren 10 und das Ausgleichsmassenteil 11 seitlich umgrenzt.In the embodiment according to Fig. 3 has the counter-profile 9 has a substantially cross-sectionally U-shaped configuration with angled towards each other end of the side legs 9.1. These angled ends embrace the also partially U-shaped angle section 7.2, which in turn bounds the two insulators 10 and the compensating mass portion 11 laterally.

Zwischen dem abgewinkelten Ende des Seitenschenkels 9.1 des Gegenprofils 9 und der Vorderwandung des Winkelprofilteils 7.2 ist ein Spalt 15 vorgesehen, der eine Ausdehnung der Isolatorschichten um ein gewisses Maß erlaubt, jedoch nach Ausfüllung des Spaltes 15 ein weiteres Ausdehnen von der Schalungswandung 3 weg in Richtung der Führungsschiene 2 begrenzt. Dadurch ist es möglich, die Schrauben 4 ohne das Erfordernis einer späteren Wartung bei der Montage auf ein bestimmtes Maß anzuziehen, ohne dass die Gefahr besteht, dieses später überprüfen zu müssen. Des weiteren ist dadurch sicher gestellt, dass das Dämmverhalten der Isolatoren 10 nicht durch Setz- und Alterungserscheinungen aufgrund eines unkontrollierten Ausdehnungsverhaltens verändert wird.Between the angled end of the side leg 9.1 of the counter-profile 9 and the front wall of the angle section 7.2 a gap 15 is provided which allows an expansion of the insulator layers to a certain extent, but after filling the gap 15 further expansion of the shuttering wall 3 away in the direction of Guide rail 2 limited. This makes it possible to tighten the screws 4 without the need for later maintenance during assembly to a certain extent, without the risk of having to check this later. Furthermore, this ensures that the insulating behavior of the insulators 10 is not changed by settling and aging phenomena due to an uncontrolled expansion behavior.
