The threaded bolts 21 are inserted through the passage openings 20 and into the openings 28 screwed in the crosspiece 27 of the profile rails 1. The bolt head is located protected in the area between the two triangular ones Side walls 23, 24. The web 26 lies on the outside of the wall 19 flat. The profile part 25 also lies with its flat end face on the corresponding flat end face 22 of the respective connection 3 to 6 of the connector 2.

In der Stirnseite 22 des Anschlusses 3 befindet sich eine durchgehende Nut 31, in die eine Trockendichtung 32 (Fig. 2 bis 4) eingelegt wird. Sie besteht vorteilhaft aus Silikon, kann aber auch aus Polytetrafluorethylen, aus Polyethylen, aus Gummi oder dergleichen bestehen. Die Trockendichtung 32, die vor dem Ansetzen der Profilschienen 1 an das Verbindungsstück 2 in die Nuten 31 eingelegt wird, ist in ihrer Form an die Form der Stirnseite 22 des jeweiligen Anschlusses 3 bis 6 angepaßt. Die als Formteil ausgebildete Trockendichtung 32 hat dementsprechend zwei endseitige, parallel zueinander liegende Schenkel 33, 34, die durch jeweils ein senkrecht zu ihnen verlaufendes Verbindungsstück 35, 36 mit inneren Schenkeln 37 und 38 verbunden sind. Sie liegen parallel zueinander und zu den äußeren Schenkeln 33, 34 und sind am anderen Ende durch einen Quersteg 39 miteinander verbunden. Die äußeren Schenke 33, 34 liegen in der Einbaulage in den den Seitenwänden 8, 9 zugeordneten Nutenabschnitten des Verbindungsstückes 2. Die inneren Schenke 37, 38 liegen in den den Seitenwänden 12, 13 des Verbindungsstückes 2 zugeordneten Nutenabschnitten, während der Quersteg 39 in den der Decke 16 zugeordneten Nutenabschnitt eingesetzt wird. Der Boden 14 der Anschlüsse 3 bis 6 ist nicht mit einer Nut versehen.In the end face 22 of the connection 3 there is a continuous Groove 31, in which a dry seal 32 (Fig. 2 to 4) is inserted becomes. It is advantageously made of silicone, but can also be made of polytetrafluoroethylene, made of polyethylene, rubber or the like. The dry seal 32, which is before attaching the rails 1 is inserted into the connector 31 in the grooves 31 in their shape to the shape of the end face 22 of the respective connection 3 to 6 adjusted. The dry seal designed as a molded part Accordingly, 32 has two ends that are parallel to one another Legs 33, 34, each by a perpendicular to them Connector 35, 36 with inner legs 37 and 38 are connected. They are parallel to each other and to the outside Legs 33, 34 and are at the other end through a crossbar 39 connected. The outer legs 33, 34 are in the Installation position in the groove sections assigned to the side walls 8, 9 of the connecting piece 2. The inner legs 37, 38 lie in the side walls 12, 13 of the connecting piece 2 associated groove sections, while the crossbar 39 in the Cover 16 associated groove section is used. The floor 14 of the connections 3 to 6 is not provided with a groove.

Die Trockendichtung 32 läßt sich vor der Montage der Profilschienen 1 leicht in die Nuten 31 in den Stirnseiten der Anschlüsse 3 bis 6 des Verbindungsstückes 2 einlegen. Insbesondere kann hierbei zuverlässig überprüft werden, ob die Dichtung sauber eingesetzt worden ist. Die Nuten 31 in den Stirnseiten 22 der Anschlüsse 3 bis 6 sind so tief, daß die Trockendichtungen 32 sicher in den Nuten gehalten werden. Dadurch ist gewährleistet, daß die Trockendichtungen 32 bei der Montage der Profilschienen 1 nicht unbeabsichtigt herausfallen oder innerhalb der Nuten 31 verrutschen. Die Trockendichtungen 32 stehen geringfügig aus den Nuten 31 vor, so daß sie beim Anschrauben der Profilschienen 1 elastisch zusammengedrückt werden, da die Profilteile 25 der Profilschienen 1 gleiches Querschnittsprofil wie die Anschlüsse 3 bis 6 haben. Auf diese Weise wird eine einwandfreie Abdichtung im Stoßbereich zwischen den Profilschienen 1 und den Anschlüssen 3 bis 6 erreicht. Der Einsatz der Trockendichtungen 32 hat den Vorteil, daß sie mehrmals verwendet werden können, so daß nach einer Reparatur am Deckenraster die Trockendichtungen erneut eingesetzt werden können. Hinzu kommt, daß die Trockendichtung 32 ein preisgünstiges Bauteil ist.The dry seal 32 can be installed before mounting the rails 1 easily into the grooves 31 in the end faces of the connections 3 to 6 of the Insert connector 2. In particular, this can be reliable check whether the seal has been inserted properly. The grooves 31 in the end faces 22 of the connections 3 to 6 are like this deep that the dry seals 32 are held securely in the grooves. This ensures that the dry seals 32 in the Assembly of the profile rails 1 does not accidentally fall out or slip within the grooves 31. The dry seals 32 are slightly out of the grooves 31, so that they are screwed on the rails 1 are compressed elastically, because the Profile parts 25 of the rails 1 the same cross-sectional profile as that Have connections 3 to 6. This way, a flawless one Sealing in the joint area between the profile rails 1 and Connections 3 to 6 reached. The use of dry seals 32 has the advantage that they can be used several times, so that the dry seals again after a repair on the ceiling grid can be used. Add to that the dry seal 32 is an inexpensive component.

Die Trockendichtung 32 hat rechteckigen Querschnitt mit vorzugsweise abgerundeten Kanten. Dadurch läßt sich die Trockendichtung 32 einfach in die Nut 31 einlegen.The dry seal 32 preferably has a rectangular cross section rounded edges. This allows the dry seal 32 simply insert into the groove 31.

Die Nut 31 kann auch in der Stirnseite des Profilteils 25 der jeweiligen Profilschiene 1 vorgesehen sein. Auch ist es möglich, in den Stirnseiten des Anschlusses 3 und des Profilteiles 25 jeweils eine Nut für die Trockendichtung 32 vorzusehen. Sie ist dann so dick, daß sie in der Einbaulage elastisch zusammengedrückt wird, um die Dichtheit im Stoßbereich zu gewährleisten.The groove 31 can also in the end face of the profile part 25 of the respective Profile rail 1 may be provided. It is also possible in the End faces of the connection 3 and the profile part 25 each have a groove to provide for the dry seal 32. Then it is so thick that it is elastically compressed in the installation position to ensure tightness to ensure in the joint area.
