Description

Die Erfindung bezieht sich auf eine Befestigung für eine Treppe gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a fastening for a staircase according to the preamble of the main claim.

Eine gattungsbildende Deckenlochzarge ist in dem DE-GM 74 02 111 beschrieben. Diese bekannte Deckenlochzarge ist höhenverstellbar ausgebildet und dient als Rahmen für eine Bodentreppe, wobei die Einschalung für den Deckendurchbruch entfällt, da die Deckenlochzarge selbst die Einschalung bildet. Die Zarge kann ohne jegliche Verschalung einbetoniert werden und schafft somit eine Verblendung des Deckenquerschnittes. Sie ist mit Bolzen als Halteelemente ausgerüstet, die den Einbau der eigentlichen Bodentreppe ermöglichen sollen und fest angeschweißt sind.A generic ceiling hole frame is described in DE-GM 74 02 111. This known ceiling hole frame is height-adjustable and serves as a frame for a flight of stairs, the formwork for the ceiling opening being omitted, since the ceiling hole frame itself forms the formwork. The frame can be concreted in without any formwork and creates a veneer of the cross-section of the ceiling. It is equipped with bolts as holding elements that are intended to allow the installation of the actual staircase and are welded on.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsbildende Deckenlochzarge dadurch zu verbessern, daß ein beliebiger Anschluß der Halteelemente für die Treppe möglich ist und daß dadurch bei der Herstellung des Bauwerkes aufgetretene Maßdifferenzen leicht ausgeglichen werden können.The invention has for its object to improve the generic ceiling hole frame in that an arbitrary connection of the holding elements for the stairs is possible and that thereby occurring dimensional differences can be easily compensated for in the manufacture of the building.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object on which the invention is based is achieved by the teaching of the main claim.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen erläutert.Advantageous configurations are explained in the subclaims.

Mit anderen Worten ausgedrückt, wird gemäß der Erfindung vorgeschlagen, die Deckenlochzarge mit einer vorzugsweise umlaufenden, ggf. schwalbenschwanzförmigen, sich nach vorne zur offenen Seite hin verengenden Nut auszurüsten, so daß an jeder beliebigen Stelle dieser Nut und damit dieser Deckenlochzarge die Halteelemente für die Teile der einzubauenden Treppe angesetzt werden können. Diese Halteelemente selbst sind wiederum variabel und bestehen aus zwei Klemmplatten, die in die Nut eingeführt werden und sich im Tiefsten der Nut verankern, wobei diese Klemmplatten von Gewindestangen gehalten werden, so daß ihre Höhe beliebig einregelbar ist. Diese Gewindestangen tragen dann gleichzeitig Stufenschuhe, die die Stufenköpfe rahmenförmig umgreifen und in die die Stufenköpfe eingesetzt werden. Es ist hieraus ersichtlich, daß jede beliebige Treppenstufenbreite und damit auch alle beliebigen Treppenläufe, wie geradliniger Treppenlauf, 1/4 und 1/2-gewendelter Treppenlauf sowohl rechts als auch links gewendelt und jede beliebige Stufenhöhe eingesetzt werden können trotz Verwendung einer vorgefertigten Befestigung.In other words, it is proposed according to the invention to equip the ceiling hole frame with a preferably circumferential, possibly dovetail-shaped groove that narrows towards the open side, so that the retaining elements for the parts at any point on this groove and thus this ceiling hole frame of the stairs to be installed. These holding elements themselves are in turn variable and consist of two clamping plates which are inserted into the groove and anchor themselves in the deepest of the groove, these clamping plates being held by threaded rods so that their height can be adjusted as desired. These threaded rods then simultaneously wear step shoes, which surround the step heads in a frame shape and into which the step heads are inserted. It can be seen from this that any desired stair width and thus also any stair runs, such as straight stair flights, 1/4 and 1/2-curled stair flights can be turned right and left and any step height can be used despite the use of a prefabricated fastening.

Auch nachträgliche Veränderungen der Treppe werden durch die Befestigung erleichtert.Subsequent changes to the stairs are also facilitated by the attachment.

Vorzugsweise weist die Zarge an ihrer Oberseite oder auch an ihrer Unterseite Gewindeschraubhülsen auf, die den Einbau von Zusatzbauteilen für die spätere Wohnungsausgestaltung aufnehmen können.The frame preferably has threaded screw sleeves on its upper side or also on its lower side, which can include the installation of additional components for later home design.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen erläutert. Die Zeichnungen zeigen dabei in

  • Fig. 1 schematisch einen Schnitt durch die Deckenlochzarge, in
  • Fig. 2 in größerem Maßstab die Einzelbauteile für die an diese Deckenlochzarge anzuschließenden Halteelemente und in
  • Fig. 3 schematisch eine Seitenansicht in verkleinertem Maßstab auf eine Stufenanordnung bei Einsatz der Deckenlochzarge.
An embodiment of the invention is explained below with reference to the drawings. The drawings show in
  • Fig. 1 shows schematically a section through the ceiling hole frame, in
  • Fig. 2 on a larger scale the individual components for the holding elements to be connected to this ceiling hole frame and in
  • Fig. 3 shows schematically a side view on a reduced scale on a step arrangement when using the perforated ceiling frame.

In Fig. 1 ist mit 1 eine Deckenlochzarge bezeichnet, die eine senkrechte Wand 2 und einen unteren horizontalen Flansch 3 sowie einen oberen horizontalen Flansch 4 aufweist. Die Deckenlochzarge 1 begrenzt eine Betondecke, von der ein Teil bei 5 dargestellt ist. Sie hat den Vorteil, daß sie nach vorgegebenen Maßen angefertigt werden kann und gleichzeitig mit den herkömmlichen Deckeneinschalarbeiten verlegt werden kann. Die Profilhöhe der Deckenlochzarge 1 bestimmt dabei die Deckenstärke und die Decke 5 kann über den oberen horizontalen Flansch 4 glatt abgezogen werden.In Fig. 1, 1 designates a perforated ceiling frame which has a vertical wall 2 and a lower horizontal flange 3 and an upper horizontal flange 4. The ceiling hole frame 1 delimits a concrete ceiling, part of which is shown at 5. It has the advantage that it can be made to the specified dimensions and can be laid at the same time as the conventional ceiling formwork. The profile height of the ceiling hole frame 1 determines the ceiling thickness and the ceiling 5 can be pulled off smoothly via the upper horizontal flange 4.

Bei dem dargestellten Ausführungsbeispiel ist in dem oberen Flansch 4 eine Gewindeschraubhülse 6 vorgesehen, in die Zusatzbauteile 7 eingeschraubt werden können, wobei während der Betonierungsarbeiten die Gewindeschraubhülse 6 durch sogenannte Blindschrauben verschlossen wird.In the illustrated embodiment, a threaded screw sleeve 6 is provided in the upper flange 4, into which additional components 7 can be screwed, the threaded screw sleeve 6 being made by so-called blind screws during the concreting work is closed.

In der senkrechten Wand 2 ist eine umlaufende Nut 8 angeordnet, die ein Schwalbenschwanzprofil aufweist, wobei der engere Teil des so gebildeten Schwalbenschwanzes zur senkrechten Wand hin - also nach vorne hin - gerichtet ist.A circumferential groove 8 is arranged in the vertical wall 2 and has a dovetail profile, the narrower part of the dovetail formed in this way being directed towards the vertical wall - that is, towards the front.

In diese umlaufende Nut 8 können Halteelemente 9 eingesetzt und befestigt werden, die der Halterung der eigentlichen Treppenstufen dienen. Wie aus der Darstellung in Fig. 1 ersichtlich, ist _ da die Nut 8 umlaufend gestaltet ist _ jede beliebige Anschlußmöglichkeit gegeben.In this circumferential groove 8 holding elements 9 can be used and fastened, which serve to hold the actual stairs. As can be seen from the illustration in Fig. 1, _ since the groove 8 is designed circumferentially _ any connection possibility is given.

Die Halteelemente 9 sind in Fig. 2 größer dargestellt und bestehen bei dem dargestellten Ausführungsbeispiel aus zwei Klemmplatten 10 und 11, die auf einer Gewindestange 12 frei verschieblich angeordnet sind. Die Klemmplatten 10 und 11 weisen dabei an ihrer dem Befestigungsende bezüglich der Gewindestange 12 abgewandten Ende Fingerlappen 14 und 15 auf, wobei die Fingerlappen der oberen Klemmplatte 10 nach unten gerichtet sind und zwei im Abstand voneinander angeordnete Fingerlappen 14 vorgesehen werden, während der Fingerlappen 15 an der unteren Klemmplatte 11 nach oben gerichtet ist und in der Mitte der Klemmplatte sitzt, so daß er die beiden Fingerlappen 14 der oberen Klemmplatte 10 durchgreifen kann. Diese Anordnung wird deutlich aus Fig. 1, wo die beiden Klemmplatten 10 und 11 dicht aufeinanderliegen und die Fingerlappen 14 und 15 dadurch nach oben und unten ausgefahren sind und sich in das Tiefste der Nut 8 einlegen. Die Klemmplatten 10 und 11 werden bei dem in Fig. 1 dargestellten Ausführungsbeipiel durch einfache Schrauben auf der Gewindestange 12 gesichert, während bei dem in Fig. 2 dargestellten Ausführungsbeispiel Schraubhülsen 16 und 17 vorgesehen sind, die die gleiche Funktion wie die Schrauben in Fig. 1 übernehmen, aber zusätzlich die Möglichkeit bieten, daß die das Gewinde der Gewindestange 12 verdeckenden Zierhülsen 18 in diese Schraubhülsen eingesetzt werden können, wo sie beispielsweise durch eine Madenschraube 19 festgelegt werden. Außerdem wird durch die Gewindestangen 12 eine Höhenausgleichsmöglichkeit erreicht.The holding elements 9 are shown larger in FIG. 2 and, in the exemplary embodiment shown, consist of two clamping plates 10 and 11, which are arranged so as to be freely displaceable on a threaded rod 12. The clamping plates 10 and 11 have finger tabs 14 and 15 on their end facing away from the fastening end with respect to the threaded rod 12, the finger tabs of the upper clamping plate 10 being directed downward and two finger tabs 14 arranged at a distance from one another, while the finger tab 15 is on the lower clamping plate 11 is directed upwards and sits in the middle of the clamping plate so that it can reach through the two finger tabs 14 of the upper clamping plate 10. This arrangement is clear from Fig. 1, where the two clamping plates 10 and 11 lie close together and the finger lobes 14 and 15 are extended up and down and lie in the deepest of the groove 8. The clamping plates 10 and 11 are in the exemplary embodiment shown in FIG. 1 secured by simple screws on the threaded rod 12, while in the embodiment shown in Fig. 2 screw sleeves 16 and 17 are provided, which perform the same function as the screws in Fig. 1, but additionally offer the possibility that the thread of the threaded rod 12 covering decorative sleeves 18 can be used in these screw sleeves, where they are fixed, for example, by a grub screw 19. In addition, a height compensation option is achieved by the threaded rods 12.

Die Gewindestangen 12 tragen weiterhin Stufenschuhe 20, die einen Aufnahmeraum 21 aufweisen, in den der Kopf einer Treppenstufe eingesetzt werden kann. Dieser Treppenstufenkopf weist dabei dann eine Bohrung auf, die von der den Stufenschuh durchquerenden Gewindestange 12 durchgriffen wird.The threaded rods 12 continue to wear step shoes 20 which have a receiving space 21 into which the head of a stair step can be inserted. This stairway step head then has a bore through which the threaded rod 12 passes through the step shoe.

In der Zeichnung nicht dargestellt ist die Möglichkeit, daß in den Stufenschuhen elastische Auflageplatten für die aufzunehmenden Treppenstufenköpfe vorgesehen sind, so daß jede Schallübertragung verhindert wird. Außerdem bietet dieser in Fig. 2 dargestellte Stufenkopf die Möglichkeit, daß die Stufen mit einer Teppichbodenumhüllung versehen werden und die Stoßnaht dieser Umhüllung im Inneren des Stufenschuhes liegt und hier verborgen ist.Not shown in the drawing is the possibility that elastic support plates are provided in the step shoes for the stair tread heads to be accommodated, so that any sound transmission is prevented. In addition, this step head shown in FIG. 2 offers the possibility that the steps are provided with a carpet covering and the butt seam of this covering lies inside the step shoe and is hidden here.

Die durch die vorbeschriebene Anordnung erzielten Vorteile werden deutlicher aus der Darstellung in Fig. 3. In Fig. 3 ist mit 22 und 23 je ein Handlauf bezeichnet, der an den Gewindestangen 12 angeordnet sein kann. Im übrigen sind die gleichen Bezugszeichen wie in Fig. 1 und 2 eingesetzt und es ist aus dieser Darstellung besonders deutlich ersichtlich, daß es ohne Schwierigkeiten möglich ist, die in die Nut 8 der Zarge 1 eingreifenden Halteelemente 9 in Richtung der Zarge zu verschieben und damit jede gewünschte Wendelung oder Gestaltung der Treppe zu erreichen. Weiterhin wird aus der Darstellung in Fig. 3 deutlich, daß durch den Einsatz der Gewindestangen 12, die mit Außengewinde ausgerüstet sind, jede beliebige Höheneinstellung sowohl des Stufenschuhes 20 wie auch der Halteelemente 9 in Bezug auf die Zarge 1 möglich sind.The advantages achieved by the arrangement described above can be seen more clearly from the illustration in FIG. Otherwise, the same reference numerals are used as in Fig. 1 and 2 and it is off This representation can be seen particularly clearly that it is possible without difficulty to move the retaining elements 9 engaging in the groove 8 of the frame 1 in the direction of the frame and thus to achieve any desired winding or design of the stairs. Furthermore, it is clear from the illustration in FIG. 3 that by using the threaded rods 12, which are equipped with an external thread, any desired height adjustment of both the stepped shoe 20 and the holding elements 9 with respect to the frame 1 is possible.

Durch diese Anordnung ist es also in einfachster Weise möglich, bei der Herstellung eines Bauwerks auftretende Maßtoleranzen auszugleichen und trotz einer einheitlich gefertigten Befestigung jede beliebige Treppenkonfiguration zu erreichen.With this arrangement it is possible in the simplest possible way to compensate for dimensional tolerances that occur during the manufacture of a building and to achieve any desired stair configuration despite a uniformly produced fastening.
