Description

Die Erfindung bezieht sich auf das Bearbeiten von Balken, wie sie der Zimmermann zum Herstellen der Decken in Gebäuden braucht. Diese Balken erhalten bisher in ihrer Längsrichtung etwa auf der halben Höhe einen Einschnitt, und in die beiden gegenüberliegenden Einschnitte zweier parallellaufender Balken werden die Bretter (Stakenbretter) eingeschoben (Abb. i). Die Einschnitte wurden bisher insbesondere mit ίο dem Zimmermannsbeil hergestellt, indem der Bearbeiter langsam fortschreitend durch Beilhiebe einen Einschnitt für die Stakenbretter aushob.The invention relates to the processing of beams such as those used by the carpenter to manufacture who needs ceilings in buildings. So far, these bars get in their longitudinal direction Make an incision about halfway up, and in the two opposite incisions The boards (peg boards) are inserted into two parallel beams (Fig. i). The incisions have so far been made in particular with ίο the carpenter's hatchet by the Work slowly progressively with ax cuts to make an incision for the peg boards excavated.

Diese Art der Herstellung der Einschnitte ist ziemlich langwierig und auch sehr ungleichmäßig, da es für den Bearbeiter schwierig ist, die gerade Linie und die richtige Tiefe der Einschnitte einigermaßen sicher einzuhalten.This way of making the incisions is rather tedious and also very uneven, as it is difficult for the operator to find the straight line and the correct depth of the incisions reasonably safe to adhere to.

An Stelle des Beils hat auch schon eine Art Nutenhebel Verwendung gefunden, der aber den großen Nachteil hatte, daß er sehr starke Kräfte beanspruchte. Bei diesen Hebeln sind meistens drei Arbeiter beschäftigt, und das Ausheben der tiefen Nut stellt auch dann noch große Anforderungen an die Körperkraft.Instead of the hatchet, a kind of grooved lever has already been used, but the had a great disadvantage that it required very strong forces. These levers are mostly employs three workers, and digging the deep groove is still a tough job to the physical strength.

Die Erfindung besteht in einer elektrisch betriebenen Kreissäge, die ortsbeweglich ,ist und. die Einschnitte in die Balken von Hand herzustellen gestattet. Zunächst wird ein Schlitz an Stelle der strichpunktierten Linie 12 in Abb. 2 oder 3 über die ganze Länge des Balkens 11 von der richtigen Tiefe durchgeführt. Dann wird die Handkreissäge um 180 ° gedreht und ein zweiter Schnitt gemäß Linie 13 in Abb. 2 oder 3 rückwärts über den ganzen Balken geführt, so daß dann das Winkelstück herausfällt, welches nachher durch die Stakenbretter ausgefüllt wird. Hat die benutzte Handkreissäge zwei Sägeblätter, so ist nur eine einmalige Führung der Säge den Balken entlang erforderlich, um den Einschnitt herbeizuführen.The invention consists in an electrically operated circular saw that is portable and. the cuts in the beams are allowed to be made by hand. First, a slot is made Place the dash-dotted line 12 in Fig. 2 or 3 over the entire length of the bar 11 of done at the right depth. Then the circular saw is rotated 180 ° and turned on second section along line 13 in Fig. 2 or 3 backwards over the entire beam, see above that then the elbow falls out, which is then filled by the peg boards. If the circular saw you are using has two saw blades, the Saw along the joist as needed to make the cut.

In den Abb. 4 und 5 ist die Kreissäge mit zwei Blättern dargestellt.In Figs. 4 and 5, the circular saw is shown with two blades.

Das eine Lager des Elektromotors 14 ist halsartig ausgebildet und wird von einem Lagerfuß 15 gefaßt, der an einem Gestell 16 schwenkbar befestigt ist. Der Fuß 15 hat hierzu zwei Schlitze 17, mittels deren das durch den Motor 14 angetriebene Sägenblatt 18 nach Lösen der !One bearing of the electric motor 14 is neck-like and is supported by a bearing foot 15 taken, which is pivotally attached to a frame 16. The foot 15 has two for this purpose Slots 17, by means of which the saw blade 18 driven by the motor 14 after loosening the!

Schraube 19 in verschiedenen schrägen Lagen • eingestellt werden kann. Der Krümmungsmittelpunkt der Schlitze 17 bzw. des Fußes 15 der Kreissäge liegt dabei an der tiefsten Stelle 20 des Einschnittes (Abb. 2).Screw 19 can be adjusted in different inclined positions. The center of curvature of the slots 17 or of the foot 15 the circular saw lies at the deepest point 20 of the incision (Fig. 2).

Die Tiefe des Einschnittes der Kreissäge in den Balken 11 kann dadurch beliebig verändert werden, daß man das Gestell 16 beispielsweise senkrecht in einem FHihrungssteg 21 verschiebbar anordnet. Mittels der Schrauben 22 erfolgt die Feststellung der Höhenlage der Kreissäge.The depth of the incision of the circular saw in the beam 11 can thereby be changed as desired be that the frame 16 can be displaced vertically in a guide web 21, for example arranges. The height of the circular saw is determined by means of the screws 22.

Wenn sich das Sägeblatt abgenutzt hat, so kann durch Verstellung des Gestells 16 in dem Führungssteg 21 und durch Längsverschiebung des Lagerhalses der Kreissäge auf dem schwenkbaren Fuß 15 jede beliebige Einschnittstiefe erzielt werden.If the saw blade has worn, so can by adjusting the frame 16 in the Guide web 21 and by longitudinal displacement of the bearing neck of the circular saw on the pivotable Foot 15 any incision depth can be achieved.

Die Führungsstege 21, die in der Längsrichtung der Balken vorn und hinten an der Kreissäge angeordnet sind, sind mit Rollen 23 versehen, die beim Vorschub auf dem Balken 11 laufen. Durch seitliche Rollen 24 ist eine gute Führung der ganzen Kreissäge an dem Balken 11 gewährleistet.The guide webs 21, which are in the longitudinal direction of the beams at the front and rear of the circular saw are arranged, are provided with rollers 23, which during the advance on the beam 11 to run. Lateral rollers 24 ensure that the entire circular saw is well guided on the beam 11 guaranteed.

Die Einrichtung hat den Vorteil, daß die Einschnitte der Stakenbretter von einem einzigen Mann hergestellt werden können, ohne daß dieser sonderlich angestrengt wird. Dabei gestattet die Einrichtung, vorgezogene Linien auf dem Balken genau einzuhalten und die Tiefe des Einschnittes und auch den Schnittwinkel des herauszunehmenden Zwickels beliebig groß zu wählen.The device has the advantage that the incisions of the peg boards from a single Man can be produced without this being particularly strained. Allowed the facility to strictly adhere to the drawn lines on the beam and the depth of the incision and also the cutting angle of the gusset to be removed can be of any size to choose.
