Description

  • Die Erfindung betrifft einen Rahmen für insbesondere Doppelbodenplatten. The invention relates to a frame for in particular floor panels.
  • Bei derartigen Bodenplatten besteht ein Problem darin, daß die Biegekante zwischen an der Trittfläche der Platte liegendem Schenkel einerseits und die Seitenkante der Platten bildendem Teil des Rahmenbleches andererseits einen Radius von in der Regel mindestens etwa 1 mm aufweist. In such floor panels, there is a problem in that the bending edge between lying at the tread surface of the panel leg on the one hand and the side edge of the plate-forming portion of the frame plate on the other hand has a radius of usually at least about 1 mm. Dadurch bildet sich bei einem Aneinanderlegen der Platten ein entsprechend großer Spalt, der in der Praxis unerwünscht ist. Thus, a correspondingly large gap, which is undesirable in practice formed in a juxtaposing of the plates. Besonders störend wirkt dieser Spalt zB, wenn die Bodenplatten mit einem dünnen Hartbelag als Trittflächenbelag versehen werden. Particularly troublesome in this gap acting example, if the floor panels are provided with a thin hard coating as a tread surface covering. In solchen Fällen kann es nämlich passieren, daß der Hartbelag durch Belastung, zB durch auf diese Stelle mit Pfennigabsätzen auftretende Damen, einbricht. In such cases it can happen namely that the hard surface by charging, for example by appearing on this site with stiletto heels ladies breaks. Diese Gefahr besteht vor allem in den Eckbereichen der Platten. This risk is greatest in the corners of the plates.
  • Hier eine Verbesserung zu schaffen, ist die Aufgabe der vorliegenden Erfindung. Here to provide an improvement, is the object of the present invention. Alternative Lösungen dieser Aufgabe enthalten die kennzeichnenden Teile der Ansprüche 1 und 2. Alternative solutions to this object contain the characterizing parts of claims 1 and 2. FIG.
  • Bei der Lösung nach Anspruch 1 kann der auf dem Schenkel nach außen umgebogene Blechteil mit seiner freien Seitenkante derart den Seitenabschluß der Bodenplatte bilden, daß die zu einem geschlossenen Boden verlegten Platten jeweils direkt an diesem Seitenrand anliegen. In the solution according to claim 1 the bent legs on the outwardly sheet metal part with its free side edge can in such form the side closure of the bottom plate that the laid to form a closed bottom plates each rest directly on this side edge. Es ist aber auch möglich, die freien Seitenränder des nach außen umgeklappten Blechteiles an den Schenkeln seitlich um ein ganz geringes Maß von zB etwa 1/10 mm zurückstehen zu lassen, damit die Platten nicht direkt an den freien Rändern der umgeklappten Blechteile, sondern an dem darunterliegenden Rahmenprofil kontaktbildend aneinanderliegen. It is however also possible to have the free side edges of the folded-outward plate member on the arms laterally to a very low level of, for example back are about 1/10 mm, so that the plates not directly attached to the free edges of folded sheet metal parts, but on the abut underlying frame profile contact making. Entscheidend ist lediglich, daß ein Spalt in einer Größenordnung vermieden wird, wie er im vorbekannten Stand der Technik bei lediglich durch Biegen erzeugter oberen Plattenaußenkante gegeben ist. It is only important that a gap is avoided in an order of magnitude, as taught in the prior art, at only generated by bending the upper plate outer edge.
  • Bei der Lösung nach Anspruch 2 wird an den mit Sicken versehenen vorgeformten Blechprofilen nachträglich der obere Biegekantenbereich Scharfkantig ausgeformt, indem durch Einebnen der Sicken Blechmaterial gezielt in den Biegekantenbereich gedrückt wird. In the solution according to claim 2, the upper flex edge portion is Sharp edges are formed by sheet metal material is selectively pressed into the flex edge portion by flattening the corrugations to the subsequently provided with beads preformed sheet metal profiles. Wie dieses Ausformen des Biegekantenbereiches im einzelnen konkret erfolgen kann, kann der nachfolgenden Beschreibung eines Ausführungsbeispieles entnommen werden. As can be performed in detail concretely this shaping of the bending edges range, the following description of an exemplary embodiment can be removed.
  • Je ein Ausführungsbeispiel zu jeder der beiden erfindungsgemäßen Lösungen ist in der Zeichnung dargestellt. Depending on an embodiment to each of the two solutions of the invention is shown in the drawing. Es zeigen Show it
    • Fig. 1 einen Schnitt durch ein Rahmenblech-profil entsprechend der Lösung nach Anspruch 1 Fig. 1 shows a section through a frame sheet metal profile in accordance with the solution according to claim 1
    • Fig. 2 den Schnitt durch ein vorgeformtes Rahmenblechprofil als Ausgangsprofil für das Umformverfahren nach Anspruch 2 Fig. 2 is a section through a pre-formed frame plate profile as the starting profile for the forming process according to claim 2
    • Fig. 3 das Blechprofil nach Fig. 2 eingespannt in ein Umformwerkzeug Fig. 3, the sheet profile of FIG. 2 is clamped in a forming tool
    • Fig. 4 einen Schnitt durch das fertig geformte Rahmenprofilblech mit Scharfkantiger Oberkante Fig. 4 shows a section through the finished molded frame profile sheet Sharp-edged upper edge
  • Durch Zusammenschweißen von vier Rahmenblechprofilen 1 in der Form nach Figur 1 entsteht ein mit einer Masse aufüllbarer Rahmen für eine Bodenplatte. creating a aufüllbarer with a mass frame for a floor panel by welding together four frame plate profiles 1 in the form of FIG. 1 Der an der Trittflächenseite der Bodenplatte zu liegen kommende Schenkel 2 besteht aus einem ersten Teil 3, der aus dem die Seitenkante der Bodenplatte bildenden Teil 4 des Blechprofiles 1 abgebogen ist und einem zweiten Teil 5, der auf den Teil 3 nach außen umgebogen ist. The to lie on the tread surface side of the bottom plate next leg 2 consists of a first part 3 which is from the side edge of the bottom panel forming part 4 of the sheet metal profile 1 is bent and a second part 5 which is bent over on the part 3 to the outside. Der freie Seitenrand 6 bildet den Seitenabschluß der späteren Bodenplatte. The free side edge 6 forms the side closure of the later base plate. Dabei kann dieser von dem freien Seitenrand 6 gebildete Abschluß mit dem am weitesten außen liegenden Bereich des Teiles 4 des Blechprofils 1 übereinstimmen. In this case, this match formed by the free side edge 6 terminating with the outermost region of the part 4 of the sheet profile. 1 Der freie Seitenrand 6 kann aber auch geringfügig, dh etwa 1/10 mm gegenüber dem äußersten Bereich des Teiles 6 zurück- oder vorstehen. however, the free side edge 6 may also slightly, that is about 1/10 mm relative to the outermost portion of the member 6 back or projecting.
  • Auch der untere Schenkel 13 des Blechprofiles 1 kann nach außen auf sich selbst zurückgebogen sein. And the lower leg 13 of the sheet metal section 1 may be folded back onto itself outwards. Dabei ist es allerdings nicht erforderlich, daß der zurückgebogene Teil bis ganz nach außen ragt. It is not necessary, however, that the bent-back portion extends fully to the outside.
  • In Fig. 2 ist das Ausgangsblechprofil für das Verfahren nach Anspruch 2 dargestellt. In FIG. 2, the output sheet profile for the process according to claim 2 is shown. Das dortige Blechprofil 7 besitzt U-förmige Grundform. The sheet metal profile 7 has local U-shaped basic shape. Nahe der Biegekante 8 ist eine Längssicke 9 in das Blechprofil eingeformt. Close to the bending edge 8 is a longitudinal bead is formed in the sheet profile. 9
  • Zur Ausbildung einer exakt rechteckigen Biegekante 8 wird das Blechprofil 7 in ein Veformwerkzeug eingespannt. In order to form an exactly rectangular bent edge 8, the sheet profile 7 is clamped in a Veformwerkzeug. Dieses Werkzeug besteht im einzelnen aus einer Aufnahme 10, einer Niederhalteplatte 11 und einer Druckplatte 12. Um die Sicke 9 einzuebnen und damit einen Materialfluß in Richtung der Biegekante 8 zu bewirken, wird das Werkzeug wie folgt betätigt: This tool consists in detail of a receptacle 10, a hold-down plate 11 and a pressure plate 12. In order to planarize and the bead 9 thus to effect flow of material in the direction of the bending edge 8, the tool is operated as follows:
  • Das Blechprofil 7 wird mit seiner Innenkontur in die Aufnahme 10 eingelegt und mit der Niederhalteplatte 11 festgeklemmt. The sheet metal profile 7 is inserted with its inner contour in the holder 10 and clamped by the hold-down plate. 11 Mit der Druckplatte 12 wird die Sikke 9 planeben so verformt, daß die Auswölbung der Sicke 9 in Richtung der rechtwinkligen Biegekante 8 fließt. With the pressure plate 12, the Sikke 9 is extremely even deformed so that the convexity of the bead 9 flows in the direction of the right-angled bending edge. 8
  • Das fertige Blechprofil mit einer tatsächlich Scharfkantigen bzw. rechteckigen Biegekante 8, bei dem die Sicke 9 eingeebnet ist, zeigt Figur 4. The finished sheet metal profile with an actual or sharp-edged rectangular bent edge 8, in which the bead is leveled 9, is shown in FIG. 4
