Field
[0001] The invention relates to a sealing arrangement for a glazed balcony
Background
[0002] People do not want walls that hinder visibility on their balcony or terrace or on
some other space to be protected but, on the other hand, an open balcony is windy
and possibly even cold. However, visibility and protection from wind can be provided
with a balcony glazing system that comprises several panes usually made of glass.
The panes may also be turned aside, or pushed into either side, when necessary.
[0003] A problem with glazed balconies is that, in spite of the glazing, cigarette smoke
or smoke from barbecuing or some other undesired or even harmful smell may drift especially
from a balcony below. In some places, the fire regulations require that smoke and
combustion gases be prevented from traveling from a lower balcony to the one above
it.
[0004] It is known to try to eliminate the above-mentioned problems with silicone or some
other sealing paste extruded from a tube by extruding it between the balcony slab
end and the bottom part of a laminar balcony railing or in the slots between a toe
rail and surrounding structures. Adhesive seals are also known. However, the known
solutions are not necessarily very good in terms of implementation and service durability.
[0005] Therefore, there is a need for a novel sealing arrangement for sealing a glazed balcony.
Brief description
[0006] An object of the invention is to provide an improved sealing arrangement for a glazed
balcony.
This is achieved by the glazing arrangement of claim 1.
[0007] Preferred embodiments of the invention are disclosed in the dependent claims.
[0008] The sealing arrangement of the invention provides several advantages, such as good
sealing ability, mountability and endurance of operating conditions.
List of figures
[0009] The invention will now be described in greater detail in connection with preferred
embodiments and with reference to the accompanying drawings, in which
Figure 1 shows a pane system, and
Figure 2 shows a mounted sealing strip between the front edge of a balcony slab and
a rail panelling as seen in the direction of the front edge of the balcony.
Description of embodiments
[0010] A pane system, that is, balcony glazing 100 comprises three panes 120, 122, 124,
for instance. Each pane may be made of glass or some other material that permeates
light to a desired extent and in a desired manner. The pane system 100 may comprise
at least one pane 120 that is not movable, while panes 122, 124 are movable by sliding.
[0011] The panes are between a top rail structure 130 and a bottom rail structure 140. On
the top and bottom edges of the actual glass portion of the panes 120, 122, 124, there
are support structures, by means of which the panes are supported to the top rail
structure 130 and the bottom rail structure 140. The bottom rail structure 140 may
be supported to the top rail 144 of the railing, which top rail 144 also serves as
the top support of the railing panelling 800, that is, cover plate structure 800.
The bottom rail 140 and the top rail 144 of the railing may also be integrated into
one and the same rail.
[0012] The invention relates to a sealing arrangement for a balcony to be furnished with
balcony glazing 100.
[0013] Reference number 200 represents the balcony slab which is either a factory-made element
or cast in place.
[0014] Figure 2 shows that the sealing arrangement comprises a sealing strip 320 equipped
with a barrier seal 310 preventing the flow of smoke or other agent and arranged in
a sealing groove 300. Thus, the sealing strip comprises a sealing groove 300 and a
barrier seal 310, such as a smoke barrier seal, therein.
[0015] Figure 2 shows that in a preferred embodiment, on both longitudinal sides or edges
of the sealing strip 320, there is a groove 300, 500 for a seal 310, 510 and in the
groove a barrier seal 310, 510, in other words, a sealing groove 300 for the seal
310 and a sealing groove 500 for the seal 510. It can be seen that the sealing strip
comprises a support 600 that connects the sealing grooves 300, 500 while the dimensions
of the support 600 have been selected on the basis of the necessary filling distance
in such a manner that the seals 310, 510 in the grooves 300, 500 are suitably compressed
in the slot 700 requiring sealing or filling between the walls of the slot, that is,
between the railing panelling 800 and the vertical end 210 of the balcony slab 200.
[0016] In an embodiment, the seal is a rubber seal made of EPDM rubber, for instance. This
way, good operating characteristics are achieved in terms of sealing ability and endurance
of operating conditions.
[0017] The sealing grooves 300, 500 and support 600 are of the same profile piece that is
most preferably made of aluminium by impact extrusion.
[0018] The sealing strip 320 should preferably be a metal profile strip, and an embodiment
where the sealing strip is an aluminium profile strip is especially practical, as
mentioned above. Thus, the smoke barrier seals 310, 510 are inserted in an extruded
profile strip preferably in such a manner that the seal fastens to the groove of the
profile strip by form-locking.
[0019] In the sealing arrangement, the sealing strip 320 with its smoke barrier seal 310
is between the horizontal balcony slab 200 and the second structural part 800 of the
balcony and in contact with both the balcony slab 200 and the second structural part
800 of the balcony.
[0020] In Figure 2, arrow A shows the prevention of smoke or other harmful flow from rising
from the lower balcony toward the bottom part of the upper balcony. The smoke may
be from a fire, smoking or cookery, or it may be some other undesired, such as malodorous,
air flow.
[0021] Even though the invention has been described above with reference to the examples
according to the attached drawings, it is clear that the invention is not restricted
thereto but may be modified in many ways within the scope of the accompanying claims.
