Description

Grundplatte für Ausbausegmente in Bergwerksbetrieben Die Erfindung bezieht sich auf eine runde Grundplatte für Ausbausegmente in Bergwerksbetrieben mit einer Aufstellfläche für das Ausbauprofil und mit einem nach oben gerichteten, die Grundplatte umfassenden Rand.Base plate for expansion segments in mining operations The invention refers to a round base plate for expansion segments in mining operations with an installation surface for the extension profile and with an upward-facing, the edge surrounding the base plate.

Bei einer vorbekannten als Kopfplatte oder Grundplatte verwendbaren Platte, die mit einem Rand ausgebildet war, wurde der Innenbereich der Grundplatte hochgekröpft, um eine unzulässige Beanspruchung des Liegenden in der Mitte der Grundplatte bei Durchbiegung des Mittelteiles zu verhindern.In the case of a previously known one, it can be used as a head plate or base plate Plate formed with an edge became the interior of the base plate Cranked up to avoid undue stress on the person lying in the middle of the base plate to prevent bending of the middle part.

Darüber hinaus ist auch eine ebene Grundplatte bekannt, bei der zusätzlich eine mittlere Verstärkungsplatte aufgebracht war.In addition, a flat base plate is also known in which, in addition a middle reinforcement plate was applied.

Demgegenüber offenbart die vorliegende Erfindung zum erstenmal, daß auch eine ebene Grundplatte ohne Mittelverstärkung möglich wird, wenn der entsprechende Rand eine besondere Ausbildung erhält.In contrast, the present invention discloses for the first time that A flat base plate without central reinforcement is also possible if the appropriate Rand receives special training.

Erreicht wird dieses gemäß der vorliegenden Erfindung dadurch, daß die Bodenplatte der Grundplatte eben ausgebildet ist und der Rand mindestens eine in Richtung senkrecht zur Bodenplatte von der Bodenplattenunterseite her gemessene Höhe von dem Dreifachen der Stärke der Bodenplatte besitzt.This is achieved according to the present invention in that the bottom plate of the base plate is flat and the edge is at least one measured in the direction perpendicular to the floor slab from the underside of the floor slab Height of three times the thickness of the base plate.

Die Erfindung wird an Hand einer Zeichnung, die ein beliebiges Ausführungsbeispiel darstellt, näher erläutert.The invention is based on a drawing showing any exemplary embodiment represents, explained in more detail.

Die Grundplatte besteht im wesentlichen aus der Bodenplatte 1, an deren Rand eine Umfangswandung 2 senkrecht mindestens um das Dreifache der Stärke der Bodenplatte 1 hochgezogen ist, so daß sich praktisch ein napfartiges Gefäß ergibt, in welches das strichpunktiert angedeutete Ausbausegment 3 eingebracht werden kann.The base plate consists essentially of the base plate 1, on the edge of which is a circumferential wall 2 perpendicular to at least three times the thickness the base plate 1 is pulled up, so that practically a bowl-like vessel results, in which the expansion segment 3 indicated by dash-dotted lines can be introduced.
