Abstract

At their ends, the frame parts (2) of the frame have connecting lugs (4, 5) which are arranged at a different height. During assembly of the frame, two frame parts (2) lie next to one another, the connecting lugs (4, 5) of which lie one above the other at a distance apart and are connected to one another by a screw connection (13). So that the frame parts (2) are connected to one another in a positive-locking manner, the frame is turned upside down and a liquid, pasty or granulated filling material is poured into a recess on the underside of the higher connecting lug (5). The filling material also flows into the bore (6) for the screw connection (13), which bore (6) is covered by a washer (16). After the filling material has solidified, the frame can be transported either in this state or in the dismantled state and put together again in the same manner. Due to this type of assembly, mechanical working of the frame parts 2 can be dispensed with. <IMAGE>

Description

Die Erfindung betrifft einen Rahmen zur Bildung von Abdeckungen an Bodenöffnungen, der zur Aufnahme von ein oder mehr nebeneinanderliegenden Deckeln oder Rosten ausgebildet und aus mehreren, mit einem Rahmenfuss und einer Rahmenwand versehenen Rahmenteilen zusammengesetzt ist, welche zur Bildung des Rahmens durch eine Schraubverbindung miteinander verbunden sind.The invention relates to a frame for forming covers at floor openings, which is designed to accommodate one or more adjacent lids or grids and is composed of a plurality of frame parts provided with a frame foot and a frame wall, which are connected to one another by a screw connection to form the frame .

Abdeckungen, bei denen ein und mehr Deckel oder Roste in einem Rahmen eingelegt sind, sind in verschiedenen Ausführungen bekannt. Solche Abdeckungen dienen dazu, Bodenöffnungen jeglicher Art, beispielsweise zur Abdeckung von Schächten und Oeffnungen in Böden und Etagen von Gebäuden wie Lagerhäusern, Werkstatthallen und anderen Gebäuden abzudecken, so dass sie begehbar oder befahrbar sind und auch leicht geöffnet werden können.Covers in which one or more lids or grids are inserted in a frame are known in various designs. Such covers serve to cover floor openings of any kind, for example to cover shafts and openings in floors and floors of buildings such as warehouses, workshop halls and other buildings, so that they can be walked on or driven over and can also be opened easily.

Bei einer bekannten Ausführungsform (CH-PS 313 512 und GB-PS 2 134 572) setzt sich der Rahmen aus mehreren Rahmenteilen zusammen. Diese Rahmenteile werden zusammengestossen und an dafür vorgesehenen Stossstellen miteinander verschraubt, so dass sie dann einen geschlossenen Rahmen bilden. Der Rahmen wird dann bündig in den Boden verlegt. Hierzu weisen die Rahmenteile eine Rahmenwand, deren oberer Rand mit dem Boden bündig ist, und einen Rahmenfuss auf, welch letzterer als Abstützung für einen Deckel oder einen Rost ausgebildet ist, mit welchem die abzudeckende Bodenöffnung abgedeckt werden kann.In a known embodiment (CH-PS 313 512 and GB-PS 2 134 572), the frame is composed of several frame parts. These frame parts are pushed together and screwed to each other at the intended joints, so that they then form a closed frame. The frame is then installed flush with the floor. For this purpose, the frame parts have a frame wall, the upper edge of which is flush with the floor, and a frame foot, the latter as a support for one Cover or a grate is formed with which the bottom opening to be covered can be covered.

Die Verwendung von einzelnen Rahmenteilen ermöglicht es, nicht nur einen Rahmen für einen einzigen Deckel oder Rost zu bilden, sondern auch Rahmen für die Aufnahme von zwei und mehr Deckeln oder Rosten zu bilden, mit denen grössere Bodenöffnungen abgedeckt werden können.The use of individual frame parts makes it possible not only to form a frame for a single lid or grate, but also to form frames for receiving two or more lids or grids with which larger floor openings can be covered.

Nachteilig ist bei den bekannten Ausführungsformen, dass der Aufwand für die Herstellung solcher Abdeckungen verhältnismässig hoch ist, da die Stossstellen der Rahmenteile und die Deckel und Roste mindestens teilweise maschinell bearbeitet werden müssen. Dies liegt an den Toleranzen der praktisch ausschliesslich in einem Giessverfahren hergestellten Rahmenteile, Deckel und Roste. Diese Toleranzen gestatten keinen einwandfreien Zusammenbau, insbesondere beim Zusammenschrauben der Rahmenteile.A disadvantage of the known embodiments is that the effort for the production of such covers is relatively high, since the joints of the frame parts and the covers and grids have to be machined at least partially. This is due to the tolerances of the frame parts, covers and gratings which are produced practically exclusively in a casting process. These tolerances do not allow proper assembly, especially when screwing the frame parts together.

Hier setzt die Erfindung ein, der die Aufgabe zugrundeliegt, einen Rahmen der eingangs beschriebenen Art so weiter auszugestalten, dass ein einfacher und exakter Zusammenbau unter Berücksichtigung der Toleranz des Deckels oder Rostes durchgeführt werden kann, ohne dass die Rahmenteile, die Deckel oder Roste bearbeitet werden müssen.This is where the invention comes in, which is based on the object of further developing a frame of the type described at the outset in such a way that a simple and exact assembly can be carried out taking into account the tolerance of the cover or grate, without the frame parts, the cover or grate being processed have to.

Diese Aufgabe wird gemäss der Erfidnung dadurch gelöst, dass zur Aufnahme der Schraubverbindung an den Enden der Rahmenteile über das Ende der Rahmenwand ragende Verbindungslappen mit mindestens einer Bohrung zur Aufnahme der Schraubverbindung angeordnet sind, von welchen Verbindungslappen an dem einen Ende der Rahmenwand ein erster Verbindungslappen gegenüber einem zweiten Verbindungslappen an dem andern Ende an der Rahmenwand tiefer angeordnet ist, derart, dass in dem Rahmen bei zwei benachbarten Rahmenteilen die Verbindungslappen mit Abstand übereinanderliegen und durch die Schraubverbindung miteinander verbunden sind. Diese Anordnung der Verbindungslappen erlaubt es, die Rahmenteile dem jeweils verwendeten Deckel oder Rost anzupassen. Hierbei ist es zweckmässig, dass der erste Verbindungslappen mit Abstand über dem untern Rand der Rahmenwand angeordnet ist, da dadurch Platz für die Unterbringung der Mutter der Schraubverbindung vorhanden ist und diese nicht über die Sohle des Rahmenfusses ragt. In ähnlicher Weise ist der zweite Verbindungslappen mit Abstand unter dem obern Rand der Rahmenwand angeordnet, so dass der Schraubenkopf der Schraubverbindung nicht über den obern Rand der Rahmenwand ragt.According to the invention, this object is achieved in that connecting tabs projecting beyond the end of the frame wall with at least one bore for receiving the screw connection are arranged at the ends of the frame parts, of which connecting tabs opposite a first connecting tab at one end of the frame wall a second connecting tab at the other end is arranged lower on the frame wall, such that the connecting tabs are spaced apart in the frame in the case of two adjacent frame parts lie one above the other and are connected by the screw connection. This arrangement of the connecting tabs allows the frame parts to be adapted to the cover or grate used. It is expedient here that the first connecting tab is arranged at a distance above the lower edge of the frame wall, since this provides space for the nut of the screw connection and does not protrude over the sole of the frame foot. Similarly, the second connecting tab is arranged at a distance below the upper edge of the frame wall, so that the screw head of the screw connection does not protrude above the upper edge of the frame wall.

Die Erfindung betrifft auch ein Verfahren zur Herstellung des Rahmens zur Bildung von Abdecköffnungen an Bodenöffnungen, dessen Aufgabe die optimale Herstellung des erfindungsgemässen Rahmens ermöglicht. Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass der Rahmen durch Anlegen von Rahmenteilen an die verwendeten Deckel oder Roste zusammengestellt und durch Schraubverbindungen zusammengehalten wird, wobei die Rahmenteile durch Ausfüllen der Hohlräume im Bereich der Schraubverbindungen und der Verbindungslappen mit einem Füllmaterial formschlüssig miteinander verbunden werden.The invention also relates to a method for producing the frame for forming cover openings at bottom openings, the task of which enables the optimal production of the frame according to the invention. This object is achieved according to the invention in that the frame is put together by applying frame parts to the lids or grids used and held together by screw connections, the frame parts being positively connected to one another by filling the cavities in the area of the screw connections and the connecting tabs with a filler material .

Die Erfindung ist anhand eines Ausführungsbeispiels in der Zeichnung dargestellt und nachfolgend beschrieben. Es zeigen:

  • Fig. 1 eine Draufsicht eines aus Rahmenteilen zusammengesetzten Rahmens,
  • Fig. 2 eine Seitenansicht des Rahmens nach Fig. 1 in vergrösserter Darstellung,
  • Fig. 3 einen Schnitt längs der Linie III - III in Fig. 1 in vergrösserter Darstellung und
  • Fig. 4 einen Schnitt längs einer weiteren Ausbildung der Verbindung zwischen zwei Rahmenteilen mittels Verbindungslappen längs der Linie IV IV in Fig. 1 in vergrösserter Darstellung.
The invention is illustrated using an exemplary embodiment in the drawing and described below. Show it:
  • 1 is a plan view of a frame composed of frame parts,
  • 2 is a side view of the frame of FIG. 1 in an enlarged view,
  • Fig. 3 is a section along the line III - III in Fig. 1 in an enlarged view and
  • Fig. 4 shows a section along a further embodiment of the connection between two frame parts by means of connecting tabs along the line IV IV in Fig. 1 in an enlarged view.

In Fig. 1 ist ein Rahmen 1 dargestellt, der aus zwei Paaren von Rahmenteilen 2 zusammengesetzt ist, die an ihren Enden durch Querrahmenteile 3 miteinander verbunden sind. Für die Verbindung der Rahmenteile miteinander und mit dem Querrahmenteile 3 sind Verbindungslappen 4, 5 vorgesehen, die an der Rahmenaussenseite angeordent sind und übereinanderliegen. Die Verbindungslappen 4, 5 weisen eine Bohrung 6 oder zwei Bohrungen 6 auf, wie auf der linken Seite von Fig. 1 dargestellt ist. Die Zahl der Bohrungen ist beliebig.In Fig. 1, a frame 1 is shown, which is composed of two pairs of frame parts 2, which are connected at their ends by transverse frame parts 3. For the connection of the frame parts to one another and to the transverse frame parts 3, connecting tabs 4, 5 are provided which are arranged on the outside of the frame and lie one above the other. The connecting tabs 4, 5 have a bore 6 or two bores 6, as shown on the left side of FIG. 1. The number of holes is arbitrary.

Jeder Rahmenteil 2 weist an seinem einen Ende einen tieferliegenden Verbindungslappen 4 und an seinem andern Ende einen höhergelegenen Verbindungslappen 5 auf. Der Querrahmenteil 3 könnte ebenfalls an seinen Enden mit je einem tieferliegenden und einem höherliegenden Verbindungslappen 4, 5 versehen sein. In Fig. 1 ist jedoch der eine Querrahmenteil an beiden Enden mit höherliegenden Verbindungslappen 5 und der andere Querrahmenteil 3 mit tieferliegenden Verbindungslappen versehen. Die Rahmenteile 2 weisen im Gegensatz zu den Querrahmenteilen 3 einen Rahmenfuss 7 auf, der sich von der Innenseite des Rahmenteils 2 auf dessen Aussenseite erstreckt. Eine Rahmenwand 8 an den Rahmenteilen 2 und den Querrahmenteilen 3 grenzt den Innenraum 10 des Rahmens 1 ab. Entsprechend den zwei Rahmenteilen auf jeder Seite des Rahmens 1 können auch zwei Deckel oder Roste (nicht dargestellt) vorgesehen werden, welche die gleiche Ausdehnung wie der Rahmenteil 2 aufweisen. Es können auch Deckel oder Rose anderer Grösse verwendet werden. Selbstverständlich ist es möglich, Rahmen mit mehr als zwei Rahmenteilpaaren auszuführen; es können auf jeder Seite beliebig viele Rahmenteile verwendet werden und soviel Deckel oder Roste wie dies zur Abdeckung der von den Rahmenteilen 2,3 gebildeten Oeffnung erforderlich ist.Each frame part 2 has a lower-lying connecting tab 4 at one end and a higher-lying connecting tab 5 at its other end. The transverse frame part 3 could also be provided at its ends with a lower and a higher-lying connecting tab 4, 5. In Fig. 1, however, the one transverse frame part is provided at both ends with higher-lying connecting tabs 5 and the other transverse frame part 3 with lower-lying connecting tabs. In contrast to the transverse frame parts 3, the frame parts 2 have a frame foot 7 which extends from the inside of the frame part 2 to the outside thereof. A frame wall 8 on the frame parts 2 and the transverse frame parts 3 delimits the interior 10 of the frame 1. Corresponding to the two frame parts on each side of the frame 1, two lids or grids (not shown) can also be provided, which have the same dimensions as the frame part 2. Lids or roses of other sizes can also be used. Of course, it is possible to design frames with more than two pairs of frame parts; any number of frame parts and so many covers can be used on each side or grates as required to cover the opening formed by the frame parts 2, 3.

In Fig. 2 ist die Anordnung der Verbindungslappen 4, 5 besser erkennbar. In Fig. 2 sind zwei Rahmenteile vollständig, d.h. mit beiden Enden, und daran anschliessend die Enden zweier weiterer Rahmenteile dargestellt.The arrangement of the connecting tabs 4, 5 can be seen better in FIG. In Fig. 2, two frame parts are complete, i.e. with both ends, and then the ends of two further frame parts shown.

Die Verbindungslappen 4, 5 liegen übereinander, wobei der tiefergelegene Verbindungslappen 4 mit Abstand über der Sohle 11 des Rahmenfusses 7 und der höhergelegene Verbindungslappen 5 unterhalb des obereren Randes 12 der Rahmenwand 8 angeordnet ist.The connecting tabs 4, 5 lie one above the other, the lower-lying connecting tab 4 being arranged at a distance above the sole 11 of the frame foot 7 and the higher-lying connecting tab 5 below the upper edge 12 of the frame wall 8.

Die beiden Verbindungslappen 4, 5 sind durch eine Verschraubung 13 verbunden, welche sich aus einem Schraubenbolzen 14, einer Mutter 15 und einer Unterlagsscheibe 16 zusammensetzt. Wie aus Fig. 2 erkennbar ist, sind die Bohrungen 6 in den beiden Verbindungslappen 4, 5 konisch ausgebildet. Im weiteren weist der höhergelegene Verbindungslappen 5 einen auf der Unterseite angeordneten Hohlraum 20 auf, während auf der Oberseite des tieferliegenden Verbindungslappens 4 zwei flache Stege 21 angeordnet sind.The two connecting tabs 4, 5 are connected by a screw connection 13, which is composed of a screw bolt 14, a nut 15 and a washer 16. As can be seen from Fig. 2, the bores 6 in the two connecting tabs 4, 5 are conical. Furthermore, the higher-lying connecting tab 5 has a cavity 20 arranged on the underside, while two flat webs 21 are arranged on the upper side of the lower-lying connecting tab 4.

In Fig. 3 ist ein Schnitt durch die Bohrungen 6 der Verbindungslappen 4, 5 dargestellt. Gleiche Bezugszeichen in Fig. 2 und 3 bezeichnen dieselben Teile. Die Darstellung nach Fig. 3 entspricht den fertigmontierten Rahmen. Hierbei wird eine formschlüssige Verbindung durch Einführen eines Füllmaterials 22 in den Hohlraum 20 und in die Bohrung 6 des höherliegenden Verbindungslappens 5 erreicht. Als Füllmaterial 22 kann geschmolzenes Aluminium, Blei oder ein synthetisches Material in flüssigem, pastösem oder granuliertem Zustand eingefüllt- werden. Dies erfolgt dadurch, dass die Rahmenteile auf den Kopf gestellt werden, wie noch im Detail erläutert wird.3 shows a section through the bores 6 of the connecting tabs 4, 5. The same reference numerals in FIGS. 2 and 3 denote the same parts. 3 corresponds to the fully assembled frame. Here, a positive connection is achieved by introducing a filling material 22 into the cavity 20 and into the bore 6 of the higher-lying connecting tab 5. Molten aluminum, lead or a synthetic material in the liquid, paste or granulated state can be filled in as filler 22. This is done by turning the frame parts upside down, as will be explained in detail.

In Fig. 4 ist eine ähnliche Verbindung zweier Rahmenteile mit ihren Verbindungslappen 4, 5 dargestellt, wobei hier zwei Bohrungen 6 und entsprechend zwei Verschraubungen 13 verwendet werden. Ein weiterer Unterschied besteht darin, dass hier der tieferliegende Verbindungslappen 4 auf seiner Oberseite einen Hohlraum 23 aufweist, während der höherliegende Verbindungslappen 5 auf seiner Unterseite einen Steg 24 aufweist. Die formschlüssige Verbindung der beiden Verbindungslappen 4, 5 wird dadurch erreicht, dass das Füllmaterial 22 in den Hohlraum 23 und in die Bohrungen 6 des tieferliegenden Verbindungslappen eingefüllt wird und dort erstarrt.4 shows a similar connection of two frame parts with their connecting tabs 4, 5, two bores 6 and correspondingly two screw connections 13 being used here. Another difference is that here the lower-lying connecting tab 4 has a cavity 23 on its upper side, while the higher-lying connecting tab 5 has a web 24 on its underside. The positive connection of the two connecting tabs 4, 5 is achieved in that the filling material 22 is filled into the cavity 23 and into the bores 6 of the lower-lying connecting tab and solidifies there.

Die Montage des Rahmens nach Fig. 3 verläuft wie folgt: Der Deckel oder Rost oder die Lehre und die Rahmenteile 2,3 werden auf dem Kopf auf einer Montageunterlage aufgestellt und die Rahmenteile 2 an ihren Verbindungslappen 4, 5 miteinander verschraubt. Wenn der Deckel oder Rost oder die Lehre und die Rahmenteile 2 ausgerichtet sind, erfolgt das Einfüllen des Füllmaterials 22 in den Hohlraum 20 und in die Bohrung 6 des höherliegenden Verbindungslappens 5. Ist das Füllmaterial 22 erstarrt, kann der Rahmen durch Lösen der Mutter 15 in seine einzelnen Teile zerlegt werden, wenn dies beispielsweise für Transportzwecke erforderlich ist. An der Einbaustelle kann der Rahmen wieder in gleicher Weise zusammengebaut werden wie beim Einfüllen des Füllmaterials 22. Die konische Ausbildung der Bohrung 6 verbessert die Verbindung der Schraubenbolzen 14 mit den Rahmenteilen 2 und erleichtert das Entfernen des Schraubenbolzens, fall dies aus irgendeinem Grund erforderlich sein sollte.3 proceeds as follows: the cover or grate or the gauge and the frame parts 2, 3 are placed upside down on an assembly base and the frame parts 2 are screwed together at their connecting tabs 4, 5. When the cover or grate or the gauge and the frame parts 2 are aligned, the filling material 22 is filled into the cavity 20 and into the bore 6 of the higher-lying connecting tab 5. If the filling material 22 has solidified, the frame can be loosened by loosening the nut 15 its individual parts can be disassembled if this is necessary for transport purposes, for example. At the installation point, the frame can be reassembled in the same way as when filling material 22 is filled in. The conical design of bore 6 improves the connection of screw bolts 14 to frame parts 2 and makes it easier to remove the screw bolt, if this should be necessary for any reason .

Die Montage des Rahmens nach Fig. 4 verläuft wie folgt: Für diese Montage ist ein auf den Kopf stellen der Teile nicht erforderlich. Der Rahmen wird durch Aufstellen der Rahmenteile 2, 3, durch Einsetzen der Deckel oder der Roste oder der Lehre und durch Verschrauben der Rahmenteile mit den Verschraubungen 13 gebildet. Nun wird das Füllmaterial 22 in den Hohlraum 23 des tieferliegenden Verbindungslappens 4 eingefüllt, welches auch in die konischen Bohrungen 6 des tieferliegenden Verbindungslappen 4 fliesst, welche durch eine Unterlagsscheibe 24 geschlossen sind. Ist nach dem Erstarren des Füllmaterials 22 eine Demontage des Rahmens nicht mehr erfoderlich, können die Schraubverbindungen 13 auch umgekehrt, d.h. mit untenliegender Mutter 15, montiert werden.The assembly of the frame according to FIG. 4 proceeds as follows: For this assembly, turning the parts upside down is not necessary. The frame is made by setting up the frame parts 2, 3, by inserting the cover or the grids or the gauge and by screwing the frame parts to the screw connections 13 educated. Now the filling material 22 is filled into the cavity 23 of the lower connecting tab 4, which also flows into the conical bores 6 of the lower connecting tab 4, which are closed by a washer 24. If, after the filling material 22 has solidified, dismantling of the frame is no longer necessary, the screw connections 13 can also be mounted the other way round, ie with the nut 15 underneath.

Der beschriebene Rahmen 1 weist den wesentlichen Vorteil auf, dass die Teile des Rahmens und die Deckel oder Roste ohne maschinelle Bearbeitung montiert werden können. Trotzdem wird eine saubere Lagerung der Deckel und Roste erreicht und auch das Spiel derselben im Innenraum 10 des Rahmens kann dem Mass des Deckels oder des Rostes angepasst werden. Durch das Einfüllen eines Füllmaterials 22 erhält der Rahmen seine Stabilität.The frame 1 described has the essential advantage that the parts of the frame and the cover or grids can be assembled without machining. Nevertheless, a clean storage of the cover and grate is achieved and the play of the same in the interior 10 of the frame can be adapted to the size of the cover or grate. By filling a filling material 22, the frame gets its stability.
