Description
Der in der Zeichnung dargestellte Holzbolzenhalter ist aus diei Teilena, -b und c zusammengesetzt, und zwar aus einer das Ausbauprofil umfassenden Klammer a, einer zweiten gleichen Klammer b, die aber mit einem Ansatz für die Bolzenauflage versehen ist, und einer Laschec, Die Anbringung des Holzbolzenhadters für Grubenprofile geschieht in. der Weise, daß die Klammer a über den Fuß des entsprechenden Ausbauprofils geschoben wird, wobei der gesamte Bolzenhalter in gleichachsiger Außriiehtung verbleibt. Alsdann wird die Klammer b mit dem Ansatz für die Bolzenauflage heruntergedtrückt, wobei sich die gelenkig verbundene Lasche c schräg stellt, den Abstand zwischen den beiden Klammern a und b verringert und somit eine Klemmwirkung erzielt.The wooden bolt holder shown in the drawing is composed of diei Teilena, -b and c, namely from a bracket a encompassing the extension profile, a second same bracket b, but which is provided with an approach for the bolt support, and a Laschec, Die attachment of the Holzbolzenhadters for pit profiles is done in such a way that the bracket a is pushed over the foot of the corresponding extension profile, the entire stud holder remaining in equiaxed alignment. Then the bracket b is pressed down with the approach for the bolt support, the articulated tab c is inclined, the distance between the two brackets a and b is reduced and thus a clamping effect is achieved.
Auf den Ansatz der Bolzenauflage b kann man jetzt den vorgesehenen Hchlzbolzen auflegen, der durch sein Eigengewicht noch eine größere Klemmwirkung der Vorrichtung bewirkt. Selbst wenn der Holzbolzen zustrocknet und infolge dieses Zustandes sich nicht mehr gegen die Stege der Ausbauprofile abstützt, kann der Bolzen nicht herunterfallen, sondern wird immer in seiner ursprünglichen Lage gehalten. Ein vorschriftsmäßiges Ab- stützen der Ausbaue ist hierdurch immer gewährleistet.The intended Hchlzbolzen can now be placed on the approach of the bolt support b , which, due to its own weight, has an even greater clamping effect of the device. Even if the wooden bolt dries up and as a result of this condition is no longer supported against the webs of the extension profiles, the bolt cannot fall down, but is always held in its original position. Achieve regulatory exhaust support the Ausbaue is hereby guaranteed.
