Description

Die Erfindung betrifft ein Lager zur Auflagerung eines Tragwerkes, bestehend aus einem von miteinander, z. B. durch Vulkanisation, verbundenen Elastomer- und Metallschichten gebildeten Verbundkörper, dem zumindest an einer Lagerfläche eine aus einem Kunstharz oder einer kunstharzgebundenen Masse, z. B. einem Kunstharzmörtel bestehende härtbare Ausgleichsmasse zum Ausgleich der Maßtoleranzen zwischen dem Auflager und dem aufzulagernden Tragwerk angefügt ist.The invention relates to a bearing for supporting a structure, consisting of one of each other, for. B. formed by vulcanization, connected elastomer and metal layers, the composite at least on a bearing surface made of a synthetic resin or a resin-bonded mass, for. B. a synthetic resin mortar existing curable leveling compound to compensate for the dimensional tolerances between the support and the structure to be supported is added.

Ein solches Lager ist bereits aus der DE-A-2013897 bekanntgeworden und ist zwischen einer oberen und unteren Ausgleichsschicht zwischen dem aufzulagernden Tragwerk und dessen Auflager angeordnet. Die obere und untere Ausgleichsschicht müssen zwischen profilierten Lagerflächen durch Gießen oder Stopfen eingebracht werden, wobei darauf geachtet werden muß, daß keine luftgefüllten Hohlräume verbleiben.Such a bearing has already become known from DE-A-2013897 and is arranged between an upper and lower compensation layer between the supporting structure to be supported and its support. The upper and lower leveling layer must be inserted between profiled bearing surfaces by pouring or plugging, taking care that no air-filled cavities remain.

Somit erfordert eine ordnungsgemäße Einbringung dieser Ausgleichsschichten einen hohen Zeit- und Müheaufwand sowie ein hohes Ausmaß an Können und Geschicklichkeit. Die Einbringung wird noch zusätzlich dadurch erschwert, daß das Material der Ausgleichsschichten vor seiner Einbringung mit einem Härter vermengt werden muß und sodann nach dieser Vermengung die Einbringung unter Zeitdruck steht, weil sie bis zur Erhärtung vollzogen sein muß.Thus, the correct application of these leveling layers requires a lot of time and effort as well as a high degree of skill and dexterity. The introduction is made even more difficult by the fact that the material of the compensating layers must be mixed with a hardener before it is introduced and then the introduction is after this mixing under time pressure because it must be completed before hardening.

Aufgabe vorliegender Erfindung ist die Lösung der mit dem Einbau eines Lagers der eingangs bezeichneten Gattung verknüpften Probleme und die Schaffung eines Lagers, dessen Einbau optimal vereinfacht ist und keinen nennenswerten Mühe-, Zeit- und Geschicklichkeitsaufwand erfordert, aber dennoch wesentlich zuverlässiger als bisher eine gleichmäßige Verteilung, Übertragung und Aufnahme der Auflagerkräfte gewährleistet.The object of the present invention is to solve the problems associated with the installation of a bearing of the type mentioned at the outset and to create a bearing whose installation is optimally simplified and does not require any significant effort, time and skill, but is still much more reliable than before, even distribution , Transfer and absorption of support forces guaranteed.

Erfindungsgemäß schließt die Wandung eines die Ausgleichsmasse enthaltenden, am Verbundkörper befestigten, z. B. angeklebten oder anvulkanisierten Polsters einen z. B. durch Schlag oder Druck zerstörbaren Behälter mit einem zur Härtung des im Polster befindlichen Kunstharzes geeigneten Härter ein.According to the invention includes the wall of a containing the balancing mass, attached to the composite body, for. B. glued or vulcanized pad a z. B. by impact or pressure destructible container with a hardener suitable for hardening the synthetic resin located in the cushion.

Aus der. DE-A-1 956 294 ist es bekannt, einen eine Druckflüssigkeit enthaltenden Polster als bewegliches Auflager für ein Tragwerk zu verwenden, doch gehört dieses Widerlager naturgemäß nicht zu der eingangs definierten Gattung von Elastomer-Lagern mit Ausgleichsschichten, die beim Einbau einer Härtung unterzogen werden und sodann gemeinsam mit einem Verbundkörper ein ortsfestes Auflager verkörpern.From the. DE-A-1 956 294 it is known to use a cushion containing a pressure fluid as a movable support for a supporting structure, but this abutment naturally does not belong to the initially defined type of elastomer bearings with compensating layers which are subjected to hardening during installation and then embody a fixed support together with a composite body.

Die Figuren 1 bis 3 der Zeichnungen zeigen ein erfindungsgemäßes Lager in verschiedenen Einbauphasen in jeweils einem Querschnitt.Figures 1 to 3 of the drawings show a bearing according to the invention in different installation phases, each in a cross section.

Wie bekannt besteht das Elastomerlager gemäß Figur 1 aus den durch Vulkanisation miteinander verbundenen Elastomerschichten 1 und den Metallschichten 2, die von bewehrenden Stahl-Einlageblechen verkörpert sind. Bei der dargestellten Ausführungsform sind die Metallschichten 2 im Elastomer eingebettet und bilden mit diesem gemeinsam einen korrosionsfesten und kompakten Verbundkörper 3. Der oberen Lagerfläche; also der Oberseite des Verbund körpers 3, ist ein Polster mit einer schmiegsamen, verformbaren, gegebenenfalls auch elastischen Wandung 4 angefügt, der die Ausgleichmasse 5 enthält, die beispielsweise aus einem faserbewehrten Kunstharzmörtel bestehen mag und einen z. B. aus Glas od. dgl. leichtzerstörbarem Material bestehenden, mit dem für das Kunstharz des Kunstharzmörtels 5 geeigneten Härter gefüllten Behälter 6 enthält.As is known, the elastomer bearing according to FIG. 1 consists of the elastomer layers 1 connected by vulcanization and the metal layers 2, which are embodied by reinforcing steel insert sheets. In the illustrated embodiment, the metal layers 2 are embedded in the elastomer and together form a corrosion-resistant and compact composite body 3. The upper bearing surface; So the top of the composite body 3, a cushion is attached with a pliable, deformable, possibly also elastic wall 4, which contains the balancing mass 5, which may consist, for example, of a fiber-reinforced synthetic resin mortar and a z. B. glass or the like. Easily destructible material containing 5 filled with the hardener suitable for the synthetic resin of the synthetic resin mortar 6.

Zum Einbau dieses Lagers wird zuerst der Behälter 6 z. B. durch Schlag, zerstört und die in der verformbaren Wandung 4 eingeschlossene Ausgleichsmasse 5 durch Kneten mit dem Härter vermengt.To install this bearing, the container 6 z. B. by impact, destroyed and the balancing mass 5 enclosed in the deformable wall 4 mixed by kneading with the hardener.

Sodann wird gemäß Figur 2 das Lager mit dem Verbundkörper 3 auf seine Basis 7, z. B. auf ein Brückenwiderlager, aufgelegt und das Tragwerk 8 wird auf den von der Wandung 4 gebildeten Polster aufgesetzt, in die noch weiche Ausgleichsmasse 5 eingedrückt (Figur 3) und in dieser Soll-Lage bis zur Erhärtung der Ausgleichsmasse 5 fixiert.Then, the bearing with the composite body 3 on its base 7, z. B. placed on a bridge abutment and the structure 8 is placed on the cushion formed by the wall 4, pressed into the still soft balancing mass 5 (Figure 3) and fixed in this target position until the balancing mass 5 has hardened.

Die Stärke des Polsters ist so zu wählen, daß die Maßtoleranzen zwischen der Basis 7 und dem Tragwerk 8 jedenfalls aufgenommen und ausgeglichen werden können.The thickness of the upholstery is to be selected so that the dimensional tolerances between the base 7 and the supporting structure 8 can in any case be absorbed and compensated for.

Die überschüssige Ausgleichsmasse 5 kann beim Eindrücken des Tragwerkes 8 in einen seitlichen Wulst 9 (Figur 3) ausweichen oder man kann sie durch ein - nicht dargestelltes - in der Wandung 4 des Polsters anzuordnendes Überdruckventil entweichen lassen ; der verbleibende Innendruch der Ausgleichmasse 5 muß jedenfalls groß genug sein, um den Polster satt an die Unterseite des Tragwerkes 8 anzudrücken.The excess leveling compound 5 can escape when the structure 8 is pressed into a lateral bead 9 (FIG. 3) or it can be released by a pressure relief valve (not shown) to be arranged in the wall 4 of the cushion; the remaining inside pressure of the balancing mass 5 must in any case be large enough to press the cushion firmly against the underside of the supporting structure 8.

Ein werksmäßig vorgefertigter und gefüllter Polster hat den Vorteil, daß die Ausgleichsmasse 5 zuverlässig luftblasenfrei bleibt. Wird die Ausgleichsmasse 5 erst an der Baustelle in den von der Wandung 4 gebildeten Polster eingefüllt, ist auf die Luftblasenfreiheit dabei besonders zu achten ; der Polster muß möglichst luftleer sein, wenn die Ausgleichsmasse eingefüllt wird, nötigenfalls ist der Polster evakuiert anzuliefern.A factory-made and filled cushion has the advantage that the leveling compound 5 remains reliably free of air bubbles. If the leveling compound 5 is only poured into the cushion formed by the wall 4 at the construction site, special attention must be paid to the absence of air bubbles; the upholstery must be as empty as possible when the leveling compound is poured in. If necessary, the upholstery must be delivered evacuated.

Der Polster mit seiner Wandung 4 kann dem Verbundkörper 3 von vornherein, also werksmäßig, angefügt sein, so daß die Oberseite des Lagers die untere Begrenzung des Polsters bildet, oder er kann auch erst an der Baustelle vor der Verwendung des Lagers dem Verbundkörper angefügt werden.The cushion with its wall 4 can be attached to the composite body 3 from the outset, that is to say at the factory, so that the top of the bearing forms the lower boundary of the cushion, or it can also be added to the composite body only at the construction site before the bearing is used.

Claims (2)
