Abstract

Plain bearing for buildings in building and civil engineering works having an enclosed plastic layer (3) located between sliding sheet (2) or sliding plate (1) and carrier plate (5), means (6, 7, 8, 9) for measuring the distance (4) between sliding plate (1) and carrier plate (5) being provided (Figure 2).

Description

Die Erfindung betrifft ein Gleitlager für Bauwerke im Hoch- und Tiefbau mit einer Gleitplatte, an der ein Gleitblech angeordnet ist, mit einer Trägerplatte sowie mit einer zwischen Gleitblech und Trägerplatte liegender, in der Trägerplatte eingefaßter Kunststoffschicht The invention relates to a sliding bearing for structures in civil engineering with a sliding plate on which a Sliding plate is arranged, with a carrier plate and with one between the sliding plate and carrier plate lying plastic layer enclosed in the carrier plate

Derartige bewegliche Gleitlager werden für Hoch- und Tiefbauten, beispielsweise Brücken, seit langem eingesetzt (vgl. DE-AS 24 61 325). Gleitlager dieser Art, und hier insbesondere die zwischen der Gleitplatte und der Trägerplatte befindliche Kunststoffschicht, die vorzugsweise aus einem PTFE-Stück besteht, unterliegen den Wirkungen des Kaltflusses und Verschleißes.Such movable slide bearings have long been used in civil engineering, for example bridges used (see DE-AS 24 61 325). Plain bearings of this type, and here in particular between the sliding plate and the plastic layer located on the carrier plate, which preferably consists of a piece of PTFE, are subject the effects of cold flow and wear.

Es ist erforderlich, bei den genannten Bauwerken die Veränderungen der Kunststoffschicht des Gleitlagers während der Lebensdauer der Bauwerke zu kontrollieren. Dies geschieht bisher zumeist anläßlich der in bestimmten Zeitabständen vorgeschriebenen Hauptuntersuchungen durch bedingt geeignete Meßgeräte.It is necessary to change the plastic layer of the plain bearing in the structures mentioned to be checked during the life of the structure. So far, this has mostly happened on the occasion of the in General inspections prescribed at certain intervals by means of suitable measuring devices.

Aufgabe der Erfindung ist es, eine Möglichkeit zu schaffen, mit der es in einfacher Weise möglich ist, die infolge Kaltfluß und/oder Verschleiß abnehmende Kunststoffschichtdicke eines Gleitlagers jederzeit zu kontrollieren und zu messen.The object of the invention is to provide a way with which it is possible in a simple manner to as a result of cold flow and / or wear and tear, the plastic layer thickness of a plain bearing increases at any time control and measure.

Diese Aufgabe wird erfindungsgemäß in der Weise gelöst, daß dem Lagerkörper eine Einrichtung zugeordnet ist, welche seitlich der Kunststoffschicht vorgesehene Mittel zur Messung des Abstands zwischen Gleitblech und Trägerplatte sowie eine diesen Abstand anzeigende Vorrichtung aufweistAccording to the invention, this object is achieved in that a device is assigned to the bearing body is the side of the plastic layer provided means for measuring the distance between Has sliding plate and support plate and a device indicating this distance

Bei der Vorrichtung zur Messung und Anzeige des Abstandes handelt es sich vorzugsweise um eine Weg-Meßeinrichtung, die im wesentlichen aus einem handelsüblichen Meßfühler, einem der' jeweiligen Meßstelle angepaßten Winkeltrieb und einem Weg-Anzeigegerät, z. B.- einer Meßuhr, einer Digitalanzeige od. dgl. besteht.The device for measuring and displaying the distance is preferably one Distance measuring device, which essentially consists of a commercially available measuring sensor, one of the 'respective Measuring point adapted angle drive and a distance display device, z. B.- a dial gauge, a digital display or the like.

ίο Die Mittel zur Abstandsmessung sind vorteilhaft mindestens an drei Stellen des Umfangs des Gleitlagerkörpers angeordnet. Handelt es sich um einen runden Gleitlagerkörper, so werden an drei Stellen des • Umfangs die Mittel zur Abstandsmessung vorgesehen. Besitzt das Gleitlager eine rechteckige Form, so werden an jeder Seite des Rechtecks Meßstellen vorgesehen.ίο The means of distance measurement are advantageous Arranged at least at three points on the circumference of the plain bearing body. Is it a round one? Plain bearing body, the means for distance measurement are provided at three points on the • circumference. If the plain bearing has a rectangular shape, measuring points are provided on each side of the rectangle.

Die erfindungsgemäße Einrichtung kann bereits vor Einbau des Gleitlagers an dieses angebaut sein. Es können jedoch auch bereits in ein Bauwerk eingebaute Gleitlager nachträglich mit einer derartigen Meßeinrichtung ausgerüstet werden.The device according to the invention can already be attached to the sliding bearing before it is installed. It However, sliding bearings already built into a building can also be retrofitted with such a measuring device be equipped.

Die erfindungsgemäße Vorrichtung erlaubt es, jederzeit und ohne besondere Vorbereitungen eine verläßliche Kontrolle und Messung des Zustandes eines Gleitlagers durchzuführen.The device according to the invention allows a reliable one at any time and without special preparations Carry out control and measurement of the condition of a plain bearing.

Die Erfindung wird im folgenden anhand der schematischen Zeichnung näher erläutert. Es zeigt
F i g. 1 den Querschnitt eines Gleitlagers und
F i g. 2 den Ausschnitt II nach F i g. 1 in vergrößertem Maßstab.The invention is explained in more detail below with reference to the schematic drawing. It shows
F i g. 1 shows the cross section of a plain bearing and
F i g. 2 the section II according to FIG. 1 on an enlarged scale.

Im Ausführungsbeispiel nach F i g. 1 ist der Lagerkörper eines Gleitlagers dargestellt, das aus der Gleitplatte 1 mit unterwärts angeordnetem Gleitblech 2, der Trägerplatte 5 und der in dieser Trägerplatte eingefaßten Kunststoffschicht 3 in Gestalt eines PTFE-Stückes besteht.In the embodiment according to FIG. 1 shows the bearing body of a plain bearing, which consists of the sliding plate 1 with the sliding plate 2 arranged underneath, the carrier plate 5 and the plastic layer 3 enclosed in this carrier plate in the form of a piece of PTFE.

Im übrigen kann auch bei Gleitlagern in Umkehrung oben die Trägerplatte mit in ihr eingefaßter Kunststoffschicht und darunter die Gleitplatte mit Gleitblech angeordnet sein.In addition, in the case of plain bearings, the carrier plate with the plastic layer enclosed in it can also be reversed at the top and underneath the sliding plate can be arranged with sliding plate.

Anstelle des an der Gleitplatte angeordneten Gleitbleches kann auch die Gleitplatte mit einer Schicht aus Chrom od. dgl. versehen werden.Instead of the sliding plate arranged on the sliding plate, the sliding plate can also have a layer made of chrome or the like.

Gemäß F i g. 2 ist seitlich an die Trägerplatte 5 eine Lasche 9 angeschweißt, in der ein Meßfühler 6 eingelassen ist. Über einen Winkeltrieb 8 steht der Meßfühler 6 mit einer Meßuhr 7 in Verbindung.According to FIG. 2, a tab 9 is welded to the side of the carrier plate 5, in which a measuring sensor 6 is let in. The measuring sensor 6 is connected to a dial gauge 7 via an angular drive 8.

Zu messen ist der Spalt 4 zwischen dem Gleitblech 2 und der Trägerplatte 5. Dieser Abstand 4 verringert sich im Laufe der Lebensdauer des Bauwerkes infolge Kaltfluß und Verschleiß des PTFE-Stückes 3.The gap 4 between the sliding plate 2 and the carrier plate 5 is to be measured. This distance 4 is reduced During the service life of the structure as a result of cold flow and wear of the PTFE piece 3.

Selbstverständlich ist die Erfindung auch bei anderen Arten von Gleitlagern als dem hier gezeigten anwendbar, bei denen eine ständige oder eine gelegentliche Kontrolle und Messung der Dickenabnahme der eingefaßten Kunststoffschicht des Lagers vorgesehen werden muß.Of course, the invention is also applicable to other types of plain bearings than the one shown here applicable where there is constant or occasional control and measurement of the decrease in thickness the encased plastic layer of the bearing must be provided.
