DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a fire resistant glass partition having at least one field formed of a pane of fireproof glass which is equipped with fittings for fastening and/or closing elements.
2. Description of the Related Art
Fire resistant glass partitions have in the past been designed in such a way that a sash was built of metal profiles into which a pane of fireproof glass was inserted and held by appropriate glass holding strips. By appropriate cover of a fire resistant material on the faces of the metal profiles facing into a room, the required fire resistance was then realized also for the region of the metal profiles. This technique was employed for stationary glass partitions, glass partitions equipped with glass doors, as well as for fire resistant glass doors alone. Accordingly, the term "glass partition" in the sense of the present invention includes a simple fire resistant door which is formed by a single field of fireproof glass as well as multi-field stationary glass partitions with and without doors. Such glass partitions have been found to be satisfactory, but do not quite meet modern architectural requirements with respect to large-area glass partitions.
Glass partitions of normal construction and employing so-called safety glass are known to be constructed in such a way that the glass panes are fixed as self-supporting components in the wall, floor and ceiling region. Adjacent glass panes are connected with one another by a thin permanently elastic silicone putty joint. Any fittings that might be required, particularly in the door region, for door strips, locks and handles, are fastened in such a way that the glass pane is provided with holes and the fittings are fixed by through-going screws and clamping plates that rest on both sides. Even if fireproof glasses are employed, a glass partition of such a design does not meet the requirements placed on it as a fire resistant partition.
SUMMARY OF THE INVENTION
It is the object of the invention to provide a fire resistant, sash-less glass partition of the above-defined type.
This is accomplished according to the invention in that the end face of the pane is covered all around with a sealing profile made of an elastic material that grips around the edges of the pane and is provided, at least in its region facing the end face of the pane, with a material that foams when heat is applied and the sealing profile also covers the fitting components that project into the edge region, with the total thickness in the enclosed region essentially corresponding to the total thickness of the pane. Such an arrangement has the advantage that the pane can be employed as a self-supporting component, with the respective joint region, be it in the region of the wall, ceiling or floor connection, be it in the region between two mutually adjacent field formed by panes, is designed in such a way that, in the case of fire, its fire resistance is ensured for the duration of the service life of the fireproof glass employed. In the case of fire, as soon as that part of the sealing profile facing the hot side is attacked or destroyed by the heat, the foaming material is exposed to the heat and is thus able to fully foam into the existing parting groove so that, for the intended period of time, neither heat nor smoke is able to pass through to the side facing away from the fire. It is significant that the fittings lying on the glass pane in the region covered by the sealing profile together with the glass pane, of which the outer layer of the fireproof glass has been partially removed, corresponds to the total thickness of the multi-layer fireproof glass pane in this region. Thus, it is possible to provide an uninterrupted continuous fire resistant seal even on doors in which, in the case of fire, the foaming material seals the joint. Another advantage of this arrangement is that the end face of the multi-layer fireproof glass is covered and is thus protected against damage, particularly against penetration of mo
