Description
Verschalungsplatte und Verfahren zu deren Herstellung Gemäss vorliegender Erfindung ist eine an den Stirnflanken durch an den Rändern Umfassungsschen- kel aufweisende Schienen umfasste Verschalungsplatte aus Holz dadurch gekennzeichnet, dass ein im Quer schnittprofil mit Widerhaken versehener Mittelschen kel der betreffenden Schiene zwischen deren Umfas- sungsschenkel in einer Stirnflanken-Längsnut fest sitzt.
Ein Verfahren zum Herstellen derartiger Ver schalungsplatten ist erfindungsgemäss dadurch gekenn zeichnet, dass die Schienen, die zwischen ihren Um fassungsschenkeln einen im Querschnitt mit Wider haken versehenen Mittelschenkel aufweisen, von einer Längsflanke der Verschalungsplatte her in Richtung der Stirnflanken über dieselben getrieben werden, nachdem die Verschalungsplatte zur Aufnahme der Mittelschenkel mit Stirnflanken-Längsnuten und zur Aufnahme der Umfassungsschenkel mit Auskehlungen versehen worden ist.
Die Zeichnung betrifft ein Ausführungsbeispiel, der erfindungsgemässen Platte.
Eine aus aneinandergeleimten Naturholzbrettem A1, A2, A3 bestehende Verschalungsplatte ist mit einer Stirnflanken-Längsnut SN und beidseits der Stirnflanke S mit Auskehlungen K1, K2 versehen worden.
Die zum Umfassen der Stirnflanke S bestimmte Umfassungsschiene U, aus Eisen oder Leichtmetall bestehend, zeigt zwei Umfassungsschenkel U1 und U2 und einen längeren Mittelschenkel U3, dessen Profil beiderseits sägezahnförmig ist, wobei der dreieck- förmige Endzahn Z breiter ist als die übrigen Zähne. Diese Zähne erfüllen die Funktionen von Widerhaken.
Die inneren Endkanten der Umfassungsschenkel U1 und U2 sowie die Auskehlungen K1 und K2 an der Verschalungsplatte sind gerundet.
Gemäss dem erfindungsgemässen Verfahren wird nun eine solche Schiene U in Richtung,des Pfeiles P von einer Längsflanke der Verschalungsplatte her über deren Stirnflanke S getrieben, wobei sich die Zahnprofile des Mittelschenkels U3 in die Flanken der Stirnwand-Längsnut einschneiden.
Es wird also die Stirnflanke des Verschalungs brettes von der Schiene U umfasst, wie das links in der Zeichnung in strichpunktierten Linien angedeutet ist.
Da der gezahnte Mittelschenkel wegen seiner Zahnung (Widerhaken) unverrückbar in der Nut SN festsitzt, kann sich die Platte nie werfen , d. h. uneben werden, während ein gewisses Wachsen und Schwinden in der Pfeilrichtung P nicht gehindert wird.
Cladding panel and method for its production According to the present invention, a cladding panel made of wood encompassed on the end flanks by rails having surrounding legs at the edges is characterized in that a cross-sectional profile with barbed center leg of the relevant rail between its surrounding legs in a Front flank longitudinal groove is firmly seated.
According to the invention, a method for producing such formwork panels is characterized in that the rails, which have a central leg with a barbed cross-section between their circumference legs, are driven over the same from a longitudinal flank of the formwork panel in the direction of the end flanks after the formwork panel has been provided with front flank longitudinal grooves to accommodate the central limb and grooves to accommodate the surrounding limb.
The drawing relates to an embodiment, the plate according to the invention.
A cladding panel consisting of natural wood boards A1, A2, A3 glued together has been provided with a longitudinal groove SN and on both sides of the front edge S with grooves K1, K2.
The circumferential rail U, made of iron or light metal, intended to encompass the front flank S, has two encircling legs U1 and U2 and a longer central leg U3, the profile of which is sawtooth-shaped on both sides, the triangular end tooth Z being wider than the other teeth. These teeth perform the functions of barbs.
The inner end edges of the surrounding legs U1 and U2 and the grooves K1 and K2 on the shuttering panel are rounded.
According to the method according to the invention, such a rail U is now driven in the direction of arrow P from a longitudinal flank of the cladding panel over its end flank S, the tooth profiles of the center leg U3 cutting into the flanks of the end wall longitudinal groove.
So it is the end flank of the shuttering board from the rail U includes, as is indicated on the left in the drawing in dash-dotted lines.
Since the serrated middle leg is immovably stuck in the groove SN because of its serration (barbs), the plate can never throw itself. H. become uneven while some growth and shrinkage in the arrow P direction is not prevented.
