Description
Die Erfindung bezieht sich auf eine Verbesserung des Geschoßfangansatzes für Schießstände und Geschoßfänge nach Patent 728 504 und ein Verfahren zum Herstellen S der verschiedenen Schichten eines solchen verbesserten Geschoßfangansatzes.The invention relates to an improvement in the projectile catch for Shooting ranges and bullet traps according to patent 728 504 and a method for making them S of the different layers of such an improved bullet trap attachment.
Erfindungsgemäß besteht der Geschoßfangansatz aus einer unteren Schicht von etwa 25 cm Stärke aus Sand, Sägespänen und Teer und einer oberen, etwa 15 cm starken, ebenso zusammengesetzten Schicht, der aber zusätzlich etwa */2 bis 1 v. H. Glycerin beigemischt ist.According to the invention, the bullet trap approach consists of a lower layer of about 25 cm thick made of sand, sawdust and tar and an upper, about 15 cm thick, equally composed layer, but which is also about * / 2 to 1 v. H. Glycerin is added.
Glycerin hat mit einem Siedepunkt von 290 ° C die Eigenschaft, nicht zu verdampfen. Es kristallisert bei rascher Abkühlung nicht, sondern bildet selbst bei' — 400 C nur eine gummiartige Masse. Vorteilhaft ist auch, daß es keine chemische Verbindung mit TeerWith a boiling point of 290 ° C, glycerine has the property of not evaporating. It is not crystallized at rapid cooling, but forms even in '- 40 0 C only a gummy mass. Another advantage is that there is no chemical compound with tar
ao eingeht. Die Folge dieser guten Eigenschaften des Glycerins ist einerseits Frostsicherheit des Geschoßfangansatzes während der kalten Jahreszeit, andererseits Hitzebeständigkeit während des Sommers.ao is received. The consequence of these good properties of glycerine is, on the one hand, frost resistance of the bullet trap attachment during the cold season, on the other hand, heat resistance during summer.
Die Oberflächenneigung des Geschoßfang- as ansatzes beträgt zweckmäßig etwa 500.The surface slope of the approach as Geschoßfang- is expediently about 50 0th
Die untere Schicht des Geschoßfangansatzes wird nach der Erfindung dadurch hergestellt, daß der Sand auf etwa 2400 erhitzt und mit den Sägespänen und dann mit auf etwa 1400 erhitztem Teer innig gemischt wird. Die obere Schicht wird in der Weise hergestellt, daß dieser Mischung zweckmäßig mit einer Zerstäuberspritze zugesetztes Glycerin von etwa 2500 unter ständigem Untereinandermengen beigefügt wird.The lower layer of the bullet trap attachment is produced according to the invention in that the sand is heated to about 240 0 and is intimately mixed with the sawdust and then with tar heated to about 140 0. The top layer is prepared in such a manner that this mixture is added advantageously with a sprayer glycerol added of about 250 0 with constant quantities among themselves.
