Description
[0001] The invention relates to a device for finishing the edges of
floors, preferably reinforced concrete floors, of buildings and
possibly for supporting facades.
[0002] Currently, for the purpose of finishing the edges of
reinforced concrete floors, the reinforced concrete floor is
extended or widened as a single piece in the form of a thin
overhang. The facade is mounted on this extension or widening
section, which extends across the entire corresponding area of the
reinforced concrete floor. Facing elements or covering elements are
mounted on and a portion of the building-related mechanical and
utility services are provided above and below this extension or
widening section. The provision of such an extension or widening
section in a single-piece design with the reinforced concrete floor
results in a considerable formwork effort, which leads to an
increased cost and requires more construction time. The assembly of
the facing, covering and facade components is also complex.
Moreover, only a portion of the building-related mechanical and
utility installations can be accommodated.
[0003] It is the object of the invention to create a device for
finishing the edges of floors, especially reinforced concrete
floors, of buildings of the kind described above, which can be
provided in a fast and inexpensive fashion and is essentially able
to accommodate all conventional building-related installations.
[0004] To attain this object, the device for finishing the edges of
floors, preferably of reinforced concrete floors, of buildings of
the kind mentioned above is provided with the features disclosed in
claim 1.
[0005] By utilizing an embodiment of the present invention, the
complicated and complex formwork associated with forming a
reinforced concrete like finishing edge is avoided, and a support
frame, which is easily mounted after producing the prestressed
concrete or reinforced concrete floor, is created instead. The
building-related mechanical and utility installations can be easily
accommodated within the support frame. Depending on the embodiment
corresponding to the features of claims 2 and/or 3, the support
frame may be composed of cantilevers mounted side-by-side and one
after the other on the reinforced concrete floor or affixed as a
complete prefabricated unit on the reinforced concrete floor so
that the complete support frame of a building edge is delivered
preassembled to the construction site. The embodiment comprising
individual cantilevers, either individually or in a combination,
produces a weight reduction. The support frame is preferably made
of steel or aluminum.
[0006] Preferred embodiments include, in particular, adjustable
mounting parts for attaching the support frame to the building
floor or to a facade provided on the support frame having the
features recited in one or more of the claims 4 through 7.
[0007] Depending on how the building-related mechanical and utility
installations of claim 9 are accommodated, the support frame of
claim 8 is equipped with corresponding facing and/or covering
elements. The building-related mechanical and utility installations
may include, for example, cable conduits, underfloor convectors,
antiglare fixtures, sprinkler systems and the like, wherein the
support frame may be provided with a correspondingly perforated
sheet metal covering or top air grille and otherwise perforated or
non-perforated cover plates.
[0008] Pursuant to claim 10, the support frame or the individual
cantilevers preferably exhibit an approximately channel-like
configuration in cross section, wherein this also includes cross
sections in which the bottom side leg is not arranged in a
horizontal configuration, but is inclined with respect to the
horizontal plane of the building floor.
[0009] Further details of the invention are disclosed in the
following description, in which the invention is described and
explained in more detail based on the exemplary embodiment
illustrated in the drawing.
[0010] The single FIGURE shows a partially broken off schematic
representation in vertical section through a building at the outer
edge area of a building floor.
[0011] In the building 10 depicted in the drawing, a prestressed or
reinforced concrete floor 11 is represented seen from the edge,
which rests on a column 12 arranged below the floor 11 and supports
a column 12' that extends upwardly from the floor to support other
structures. Although only one column is illustrated, it will be
appreciated that typically a number of columns will be utilized and
will be arranged across the floor and separated by various
longitudinal and/or transverse sections or distances. The building
10 is surrounded or covered by a facade 13 supported at a distance
outward from the longitudinal edge 14 of the building floor 11.
[0012] An edge finishing 16 of the building floor 11 is provided
through a support frame 17, which both accommodates
building-related mechanical and/or utility installations, such as
installations 31-34, and provides a mounting connection between the
facade 13 and the building floor. The support frame 17 may be made
of stainless steel, aluminum or a similar material and may be
composed of several cantilevers 18, which are arranged periodically
along the edge 14 of the building floor 11. The support frame 17 or
the cantilevers 18 are fixed or mounted on the building floor 11,
specifically on the face edge 14 as well as also on the adjacent
surface area 15 of the building floor 11.
[0013] The cantilever 18 has an approximately channel-like
configuration seen from the side and comprises an inner leg 21
adjacent the building floor 11, an outer leg 22, which is
adjustably mounted on the facade 13, and a bottom side connecting
leg 23. In the illustrated embodiment, the inner leg 21 is longer
than the outer leg 22, while these legs are arranged approximately
at the same upper edge height, so that the connecting leg 23 is
inclined with respect to the plane of the building floor 11.
Instead of this trapezoidal channel-like cross-section or lateral
view of the support frame 17, the cantilever 18 can also be
arranged to provide approximately U-shaped channel shape.
[0014] The cantilever 18 rests with the lower area of its inner leg
21 attached to the face edge 14 of the building floor 11 via a
first adjustable mounting device 26. As illustrated, a mounting leg
24, arranged along a middle portion of the inner leg 21, may extend
horizontally over an upper surface 15 of the building floor 11 and
be attached to the building floor via a second adjustable mount 27.
The inside leg 21 and the connecting leg 23 are firmly connected to
the building floor 11 in a fashion that is not shown in detail,
wherein the alignment of the cantilever 18 can be adjusted or
varied via the two mounts 26 and 27. The mounting leg 24 can also
be held with a triangular connecting metal sheet 28.
[0015] The support frame 17, which consists of several cantilevers
18 arranged in a generally parallel and spaced arrangement, can be
prefabricated in a workshop in accordance with the length of the
affected edge of the building floor 11 by connecting several
cantilevers 18 (not shown). In this way, the support frame 17 can
be mounted as a prefabricated unit directly on the building floor
11. It is also possible to affix the cantilevers 18 individually to
the building floor 11 and subsequently connect the cantilevers 18
to form the support frame 17.
[0016] The support frame 17 may be configured to accommodate most,
if not all, conventional building-related mechanical and utility
installations or equipment, such as the cable conduit 31,
underfloor blowers or convectors 32, antiglare lighting fixtures
33, sprinkler systems 34 and the like. The bottom of the support
frame 17 or of the cantilevers 18 is formed by a facing metal sheet
36, which is mounted on the bottom of the connecting legs 23 of the
cantilevers 18. The facing metal sheet 36 can also extend into a
lower surface area 19 of the building floor 11. The top of the
support frame 17 or of the cantilevers 18 may support, for example,
air grills or vents 37 that provide outlets for the underfloor
convectors 32, and coverings 38 for shielding and/or concealing the
antiglare light fixtures 33 and sprinkler system 34. As
illustrated, the cantilever 18 includes additional reinforcement or
support elements 29 and 30.
[0017] It is understood that the support frame 17, which provides
for the attachment of the facade 13 to the building floor 11 on the
one hand, and accommodates the building-related mechanical and
utility installations 31 through 34 on the other hand, can also
incorporate a corresponding fire protection lining, as well as heat
protection and sound insulation materials.
