This invention relates to a facing of sheet metal
for residential, factory and other buildings
The invention, more precisely, relates to a facing
comprising facing elements and means for attaching the same.
Facings of the aforementioned kind are previously
known in a great number of designs and dimensions.
Conventional facings, however, which are assembled
of a plurality of elements, which often have dimensions of
about 0,5-1 m square, are designed so that between each element
grooves or elevations are located, to which attachment means
are provided. The conventional facing elements, thus, are not
designed so as to create a substantially plane front
Since recently facing elements are demanded, which
render it possible to imitate a plastered front. In Swedish
Patent No. 7711004-7, granted August 30, 1979, however, a facing
element is disclosed which yields an entirely smooth front
This facing element is mounted by fitting screw heads or the
like into keyhold-recesses in the elements. The mounting
method is relatively difficult, but the difficulty is compen-
sated for by the possibility

of exchanging every mounted element without requiring any one of
the remaining elements to be removed.
The present invention relates to a facing, which yields an entirely
smooth front, has a simpler design, is ea~ier and less expensive
to manufacture and extremely simple to mount. The invention, thus,
is an essential progress in several respects compared with said
known facing elements.
The present invention relates to a facing of the kind defined in
the preamble of the attached claim 1 and having substantially the
characterizing features as defined in the characterizing claufie
of claim 1.
The invention is described in the folaowing with reference to the
accom~anying drawings, in which
Figs. 1 and 2 show a facing element 6een from the rear side from
two different directions.
Fig. 3 is a section along the line A-A in Fig. 4.
Fig. 4 shows the front side of a facing element seen straight
from the front.

In Figs. 1-4 a facing element 1 according to the invention is shown.
In Figs. 1 and 2 the upper surface 2 Or the the facing element is
shown seen from the rear side. Every facing element has a substant-
ially plane upper surface intended to constitute the outer surfac~
of a mounted front. From the upper and, respectively, lower short
side of the facing element 1 an upper tongue ~ and, respectively,
a lower tongue 4 are formed. The tongues 3,4 extend upward and in
the direction from the upper surface 2 so as to form an angle with
the upper æurface. ~he upper tongue 3 as well as the lower one 4
are bent at their free ends, so that e~ery tongue together with
the associated bent portion 5,6 forms a ~-shaped cross-section,
as clearly appears from Fig. 5. The angle of the V is smaller than
90. The free legs of the bent portions 5,6 are seen by way of
a cross-section in parallel with the upper surface 2, which also
appears clearly from Fig. 5.
From the plane upper surface 2 of every facing element, two parallel
lateral edges 7,8 are bent downward to serve as the vertical side
surfaces of the facing element. One, 7, Or these lateral edges
is bent at its free end to a U-shaped portion 9, the bottom 10 of
which is in parallel with the upper surface. The free legs 11 of
the U-shaped portion 9, further, preferably are in parallel with
the lateral edge 7. The U-shaped portion 9, thus, forms a strip 9
pro~ecting from the bent-down side surface 7 of the facing element
1 .
The attachment means comprise a section 12 to be attached to a build-
ing wall 13 or the like by a suitable member 16. At one of its
ends, which in mounted state of the section is the end farthest remote
,

from the wall, the section 12 is formed to a portion 14 of
U-shaped cross-section. The bent portion 5 of the upper tongue
3 of a facing element 1 and the bent portion 6 of the lower tongue
4 of a facing element located next above said aforementioned facin~
element are intended at the mounting of facing elements to be
inserted into the U-shaped portions 14 of the attachment means,
as can be seen in Fig. 5 where facing elements in mounted state
are shown. The U-shaped portion 14 hereby retains the two facing
elements in vertical and horizontal direction when the upper
surfaces 2 of the facing element~ are in a vertical plane.
The bent portion 5 of the upper tongue 3 of the facing element 1
has such a length, that the bent portion 5 substantially or fully
reaches to the bottom of the U-shaped portion 14 of the attachment
means 12. When the fac~ng element is being mounted, the bent
portion 5 is connected to the U-shaped portion 14 by a screw 15,
a rivet or the like, as shown in Fig. 5. Said screw or rivet pref-
erably connects also the bottom 10 of said projecting ctrip 9 with
the U-shaped portion, as shown in Fig. 5. ~very facing element
i8 attached preferably by only one screw or rivet, but in certain
cases, depending a~o. on climatological conditions, several screws
can be used. Alternatively, in many cases the facing elemer.t can
be attached without using a screw at all.
The attachment means 12 according to a preferred embodiment com-
prises a bent sheet metal section, which has a length corresponding
to a part of or to the entire horizontal length of a wall 13 or
the like to be faced. The length of the attachment section 12
along the wall, however, also can be very short. Th_ attachment
v
1125471
section 12 preferably is designed so that the distance of the
U-6haped portion from the building wall 13 permits the mounting
of insulation material 17 between the wall 13 and the facing
elements 1.
In the foregoing a building wall 13 has been 0entioned, but the
attachment means 12 can be 6ecured also in frame work or the
like.
In Fi~s. 6 and 7 i5 shown how facing elements 1 are positioned
and attached to the ~ide of each other. ~ig. 6, which is a
6ection along the line B-B in Fig. 5 on a slightly reduced scale,
show6 that the downward bent side surface 8, which is not provided
with a projecting strip, at the mounting is positioned in the
U-6haped portion of the projecting strip 9 of a facing element
located adjacent in horizontal direction. In Fig. 7 this i6
shown on an enlarged scale. ~ig. 7, which is a section along the
line C-C in Fig. 5, the screw or rivet 15 is-indicated dashed in
order to show how it connects a facing element with the attachment
means 12.
Fig. 9 shows two lacing elements 18,19, which agree with the pre-
viously shown facing element~; 1, except for the configur`ation at
the corner 20. At the facing elements 18,19, which are intended
to constitute a corner of A building, so-called corner elements,
their lateral edge 21,22 located at the corner is bent inward
beneath the upper surface 2, so that the lateral edge on each
corner element forms an angle of sub6tantially 45 with the upper
6urface. The inward bent lateral edge 21 of one corner element 18
is bent at its free end to a U-shaped portion 23, into which the
1~2S4~7~
lateral edBe 22 of the other corner element is intended to be
inserted and secured by a screw, rivet or other connection ~not
shown).
In the lower part of ~ig. 5 the attachment means 23 for a facing
element 1 located lowermost on the wall is shown. The facing
element 1, as mentioned, is provided farthest downwardly with
its lower V-shaped portion, which consists of the lower tongue
4 and associated bent portion 6. The attachment means 23 consists
of a bent sheet m¢tal soction to be secured in a building wall
13 by a suitable member 24 or the like, the cross-section of which
at the location of the lower V-shaped portion 4,6 consists of
a V-shaped portion 25, which substantially a~rees with the form
of the V-shaped portion 4,6 of the facing element 1. This
attachment means, thus, locks the lower portion of the facing
element against movement to and from the wall 13. The attachment
means 23 further preferably comprises a portion 26 projecting
from the front and formed to serve as a drip sheet.
Facing elements for front parts located perpendicularly to the
plane of the main building front, such as about windows and doors,
so~called window and door recess elements 27,28, are secured
in the facing elements described above by a screw 32, rivet or the
like, when the facing elements adjoin a window or door recess
element. The window and door recess element may have any suitable
design, but preferably it is formed as shown in Fig. 8 whcre a
window or door recess element 27,28 is shown adjacent a window-
frame 29 with associated window-pane 30. The two parts of the
1125471
--7--
window or door recess element 27,28 are movable relative one
another and fixed in position relative one another by a screw
31, rivet or the like.
~hen mounting facing elements 1 according to the invention, after
some or all of the attachment means 12,23 have been mounted, first
the lowermost elements 1 are attached by suspending them on the
attachment means 12,23 and pushing them adjacent each other, so
that two adjacent facing elements 1 engage with each other by a
lateral edge 8 and a projecting strip 9. As appears from Fig. 7,
the lateral edge 8 can be moved at the mounting into abutment to
the lateral edge 7, so that an entirely smooth front is obtained.
The next row of facing elements 1, counted upward, are suspended
on the next following attachment means 12 and also fitted into
the attachment means 12 located next below, as appears from Fig.
5-
The present invention, thus, provides a facing comprising facing
elements and attachment means, which are extremely easy to mount.
As appears from the aforesaid, in many cases it is only necessary
to suspend the facing elements on the attachment means without
screwin~ or riveting them. Even when only one screw or rivet
i8 used, this reduces the working time and thereby the cost
substantially compared with the mounting of known facings.
Furthermore, a completely covering and substantially entirely
smooth front is obtained.
A further advantage is the possibility of positioning the facing
elements spaced from the building wall, so that additional insul-
ation of insulated buildings or the insulation of uninsulated
buildings i6 possible in a simple manner.

described above, but can be varied within the scope of the attached
claims.
