  Unterlagsplatte   fiHr Schrauben, Zugbolzen u. dgl.,   insbesondere zur Befestigung von
Schwellen,   Dielen u. dgl.   



   Den Gegenstand der Erfindung bildet eine Unterlagsplatte für Schrauben, Zugbolzen u.   dgl.,   insbesondere zur Befestigung von Schwellen, Dielen u. dgl., welche Unterlagsplatte mit einer Austiefung zur Aufnahme des versenkt gelagerten Schiaubenkopfes ausgestattet ist, so dass der obere Rand des Schraubenkopfes mit der Diele, Schwelle od. dgl. bündig abschliesst, wobei gleichzeitig der Auflagerdruck auf eine grosse   Flache übertragen wird.   



   Die Austiefung kann   zweckmässig   so der Form des Schraubenkopfes angepasst werden, dass ein Anziehen der Mutter, ohne den Kopf festhalten zu   müssen, möglich   ist. Vorzugsweise trägt die Platte am Rande eine Leiste, wodurch ein sicheres Aufsitzen und gleichzeitig eine Versteifung der Platte erzielt wird. 



   In der Zeichnung ist eine   beispielsweise Ausführungsform   des Erfindungsgegenstandes zur Darstellung gebracht, u. zw. zeigt Fig. 1 die Unterlagsplatte   gemäss   dieser   Ausführungsform   in Draufsicht mit eingesetzter Schraube, Fig. 2 einen Schnitt nach A-B der Fig. 1   in Aufriss.   



   Gemäss des dargestellten   Ausführungsbeispiels   weist die Unterlagsplatte a von quadratischer 
 EMI1.1 
 der Befestigungsschraube e passt.   Die Austiefung e   ist ihrer Höhe nach derart bemessen, dass der Kopf   d   der   Schraube e   vollkommen versenkt ist und so mit der oberen Fläche der Platte bündig liegt. 



   Die Unterlagsplatte a bildet eine wesentlich   vergrösserte Auflagerfläche,   so dass der Flächendruck verringert und hiedurch die Diele od.   dgl.,   zu deren Befestigung die Schraube dient, an der Befestigungstelle wesentlich geschont wird. Durch die Anordnung der   Randleiste b   wird ein sicheres Aufsitzen der Unterlagsplatte auf der Abstützungsfläche und gleichzeitig eine Versteifung der Platte selbst bewirkt.

  Support plate for screws, tie bolts, etc. Like., In particular for fastening
Thresholds, planks, etc. like



   The subject of the invention forms a washer plate for screws, tie bolts and. Like., In particular for attaching sleepers, boards and. Like. Which washer plate is equipped with a recess for receiving the sunk screw head, so that the upper edge of the screw head is flush with the board, threshold or the like, while at the same time the bearing pressure is transferred to a large area.



   The recess can expediently be adapted to the shape of the screw head so that the nut can be tightened without having to hold the head. Preferably, the plate carries a strip at the edge, whereby a secure seating and at the same time a stiffening of the plate is achieved.



   In the drawing, an example embodiment of the subject invention is shown, u. Between. Fig. 1 shows the base plate according to this embodiment in plan view with inserted screw, Fig. 2 shows a section along A-B of Fig. 1 in elevation.



   According to the illustrated embodiment, the base plate a has a square
 EMI1.1
 the fastening screw e fits. The height of the recess e is dimensioned in such a way that the head d of the screw e is completely countersunk and so lies flush with the upper surface of the plate.



   The base plate a forms a significantly enlarged support surface, so that the surface pressure is reduced and, as a result, the plank or the like, which the screw is used to fasten, is significantly spared at the fastening point. The arrangement of the edge strip b causes the base plate to sit securely on the support surface and, at the same time, stiffen the plate itself.



   PATENT CLAIMS:
1. Support plate for cupboards, draw bolts, etc. Like., insbesoundere for the attachment of sleepers, boards and. The like., characterized in that the base plate (a) is provided with a recess (e) for receiving the screw head (d) so that the upper edge of the screw head is flush with the board or the like.
