Abstract

The gauge has measurement regions (A, B) provided on a sheet plate. One measurement region is provided for determining external diameters of steel pipes and the other measurement region is provided for determining internal diameters of pipe clamps. Nominal size of the gauge is located for internal and external diameters of the pipes and the pipe clamps. Another measurement region (C) is provided for length and diameter of a screw. Size of a model of the gauge conforms to DIN A6. The steel pipes are used according to DIN EN 10255.

Description

Die Erfindung betrifft eine Messlehre zur Bestimmung des Außendurchmessers von Stahlrohren und des Innendurchmessers von Rohrschellen.The The invention relates to a measuring gauge for determining the outer diameter of steel pipes and the inside diameter of pipe clamps.

Es sind bereits eine Vielzahl von Messlehren bekannt. Zum Beispiel gibt es sogenannte Rachenlehren, die mit Ihrer maulartigen Öffnung zur Überprüfung von Wellen verwendet werden. Ebenso gibt es sogenannte Lehrdorne zur Überprüfung von Bohrungen. Die beiden genannten Lehren sind jeweils für ein bestimmtes Nennmaß und eine zulässige Toleranz gefertigt, d. h. man benötigt bei mehreren Nennmaßen auch mehrere Lehren. Ferner sind auch Messlehren zur Bestimmung des Verschleißes von Gabelzinken von Gabelstaplern (siehe Gebrauchsmuster DE 296 21 185 U1 ) oder des Verschleißes von Kettengliedern (siehe US-Patent US 41 50 488 A ) bekannt.There are already a variety of gauges known. For example, there are so-called throat gauges that are used with your mouth-like opening to check waves. There are also so-called teaching spikes for checking boreholes. The two mentioned teachings are each made for a specific nominal size and a permissible tolerance, ie one needs several gauges for several nominal dimensions. Furthermore, gauges for determining the wear of forks of forklifts are also available (see Utility Model DE 296 21 185 U1 ) or the wear of chain links (see U.S. Patent US 41 50 488 A ) known.

Der Erfindung liegt die Aufgabe zu Grunde, eine kompakte und einfach handhabbare Messlehre für alle gängigen Größen von Stahlrohren mit Nennweitenangaben in Zoll sowie dazu passende Rohrschellen bereitzustellen.Of the Invention is based on the object, a compact and simple manageable measuring gauge for all common ones Sizes of Steel tubes with nominal widths in inches and matching pipe clamps provide.

Für Stalleinrichtungen in der Landwirtschaft, bei Geländern und Umzäunungen sowie bei vielen Rahmenkonstruktionen werden Stahlrohre nach DIN EN 10255 mit Nennweitenangaben in Zoll sowie dazu passende Rohrschellen, auch Rohrverbinder genannt, verwendet. Diese Nennweiten entsprechen jedoch nicht dem umgerechneten Wert „Zoll in mm” (d. h. 1 Zoll = 25,4 mm), sondern es gelten folgende Werte: Nennweite Außendurchmesser ½'' 21,3 mm ¾'' 26,9 mm 1'' 33,7 mm 1¼'' 42,4 mm 1½'' 48,3 mm 2'' 60,3 mm 2½'' 76,1 mm 3'' 88,9 mm 4'' 114,3 mm 5'' 139,7 mm 6'' 165,1 mm For housing equipment in agriculture, for railings and fencing as well as in many frame constructions, steel pipes according to DIN EN 10255 with nominal widths in inches as well as matching pipe clamps, also called pipe connectors, are used. However, these nominal diameters do not correspond to the converted value "inches in mm" (ie 1 inch = 25.4 mm), but the following values apply: nominal width outer diameter ½ '' 21.3 mm ¾ '' 26.9 mm 1'' 33.7 mm 1¼ '' 42.4 mm 1½ '' 48.3 mm 2 '' 60.3 mm 2½ '' 76.1 mm 3 '' 88.9 mm 4 '' 114.3 mm 5 '' 139.7 mm 6 '' 165.1 mm

Dieser Umstand führt immer wieder zu Verwechslungen und Fehlern.This Circumstance leads again and again to confusion and mistakes.

Das Problem wird durch die im Patentanspruch 1 definierte Erfindung gelöst. Mit der Rohr- und Schellenlehre ist es möglich, auf schnelle und einfache Weise die Maße von Rohren und Schellen zu überprüfen. Hervorzuheben ist, dass die Nenn- bzw. Grenzmaße für die Innen- und Außendurchmesser auf der Lehre in umgekehrt ansteigender Reihenfolge paarweise angeordnet sind, wodurch die besonders kompakte Ausführung der Lehre möglich wird.The Problem is solved by the invention defined in claim 1 solved. With the tube and clamp gauge it is possible to fast and easy Way the measurements to check pipes and clamps. highlight is that the nominal or limit dimensions for the inner and outer diameter arranged in pairs in reverse order on the teaching are, whereby the particularly compact design of the teaching is possible.

Die Ausgestaltung gemäß Patentanspruch 2 bietet die Möglichkeit, die zum Montieren der Schellen verwendeten Schrauben ebenfalls zu vermessen (Messbereich C).The Embodiment according to claim 2 offers the possibility The screws used to mount the clamps also to measured (measuring range C).

Die Ausführung der Rohr- und Schellenlehre in Größe DIN A6 gemäß Patentanspruch 3 ergibt eine besonders handliche Variante, die für alle gängigen Größen von Rohren und Schellen verwendbar ist.The execution the pipe and clamp gauge in size DIN A6 according to claim 3 results in a particularly handy variant, which is suitable for all common sizes of Pipes and clamps is usable.

Ein Ausführungsbeispiel zeigt die Abbildung. Zur Überprüfung des Außendurchmessers von Rohren wird die Lehre mit dem Messbereich A so weit wie möglich auf das Rohr gesteckt, das zugehörige Nennmaß kann dann an der Beschriftung der Stufe abgelesen werden. Zum Überprüfen des Innendurchmessers einer Rohrschelle wird die Rohr- und Schellenlehre mit dem Messbereich B soweit möglich in die Rohrschelle gesteckt. Das Nenn-Innenmaß der Rohrschelle kann dann an der Beschriftung mit Pfeil abgelesen werden. Der Messbereich C dient zum Überprüfen der Klemmschrauben für die Rohrschelle: Der Durchmesser einer Schraube kann durch Einstecken in die entsprechende kreisrunde Aussparung überprüft werden, die Länge der Schraube kann an der Skala in mm gemessen werden.One embodiment shows the picture. To check the External diameter of tubes, the gauge with the measuring range A becomes as wide as possible the pipe is inserted, the corresponding nominal size can then be read on the label of the level. To check the Inside diameter of a pipe clamp is the pipe and clamp gauge with measuring range B as far as possible stuck in the clamp. The nominal internal dimension of the clamp can then be read off the label with the arrow. The measuring range C is used to check the Clamping screws for the clamp: The diameter of a screw can be plugged in be checked in the corresponding circular recess, the length of the Screw can be measured on the scale in mm.

Durch diese erfindungsgemäße Ausführung erhält man eine sehr handliche und einfach anzuwendende Rohr- und Schellenlehre, die überall dort eingesetzt werden kann, wo Stahlrohre und/oder dazu passende Rohrschellen gehandhabt werden, also in Lagern, in Werkstätten und auf Baustellen. Die Lehre kann zusätzlich auch mit einem Werbeaufdruck versehen werden.By this embodiment of the invention gives a very handy and easy-to-use pipe and clamp gauge, everywhere can be used where steel pipes and / or matching Clamps are handled, so in warehouses, in workshops and on construction places. The lesson can also be printed with an advertisement be provided.
