BACKGROUND OF THE INVENTION
[0001] The invention relates to a support frame according to the preamble of claim 1, and
especially to a support frame for supporting and/or fastening wall, floor, or roof
structures, the support frame comprising first and second flange parts that extend
in the longitudinal direction of the support frame, and a web extending between them.
The invention also relates to a method according to the preamble of claim 9, and especially
to a method for manufacturing a support frame for supporting and/or fastening wall
structures, the support frame comprising first and second flange parts that extend
in the longitudinal direction of the support frame, and a web extending between them.
[0002] In the wall structures and especially the partition wall structures of buildings,
support frames, or what are known as partition wall frames, are used to serve as supports
for the wall structure and to which parts of the wall structure are fastened. Horizontal
support frames, or horizontal bars, are conventionally fastened to the wall and/or
floor and/or roof structures, and vertical support frames, or vertical bars, are further
fastened to extend between the horizontal bars mounted to the roof and floor. Support
frames generally have a U- or C-shaped cross-section so that the vertical bar can
be set perpendicularly inside the support frame. If necessary, the support frame may
also be arranged to receive insulation wool that may extend between the horizontal
bars mounted to the roof and floor and between adjacent vertical bars. Wall plates
and/or surface plates or other parts of the wall structure can also be fastened to
the support frames, whereby the support frames form the body of the wall and provide
the wall structure with its rigidity. In addition, support frames are used in roof
and floor structures of buildings (roofs, floors, and base floors) as horizontal support
structures.
US 5,661,881 A discloses such a support frame.
[0003] A problem with the prior-art support frames is that their material consumption is
high, and this is the largest single cost in the manufacture of conventional support
frames. In the prior art, attempts have been made to reduce material costs by embossing,
for instance, but material savings cannot be endlessly achieved with embossing. In
addition, in these known solutions, the problem is caused by the fact that support
frames of many sizes are needed for different wall, floor and roof structures, which
means that it is necessary to manufacture several different support frames. This means
that for different construction sites, it is necessary to always have different support
frames in store and the manufacturing apparatuses also need to be occasionally adjusted
to suit the manufacture of different support frames.
BRIEF DESCRIPTION OF THE INVENTION
[0004] It is thus an object of the invention to provide a support frame and a method for
manufacturing a support frame in such a manner that the above-mentioned problems are
solved. The object of the invention is achieved with a support frame according to
claim 1. The object of the invention is further achieved with a method according to
claim 9.
[0005] Preferred embodiments of the invention are disclosed in the dependent claims.
[0006] The invention is based on providing the support frame of the invention for wall,
roof and floor structures by joining together two elongated plates. Brackets that
extend outward from the surface of the plate have been provided in the plates by cutting
and bending. In other words, cuts have been made to the plates which make it possible
to bend the parts defined by the cuts away from the surface of the plate, thus forming
an opening in the surface of the plate. The support frame is formed by joining together
two such plates with brackets provided therein as described above. The plates are
joined together by fastening together the brackets of the plates that are placed against
each other, whereby the brackets that have been fastened together extend between the
plates. In the support frame thus obtained, the plates form the flange parts of the
support frame and the joined brackets form the web extending between the flange parts.
[0007] The support frame of the invention provides the advantage that it saves material
in comparison with the prior-art support frames, because the web part of the support
frame is formed by cutting and bending the flange parts. The flange parts of the thus
formed support frame have holes and the web is made up of consecutive bridge-like
parts fastened together and formed as stated above by cutting and bending the flange
parts. This way, the flange parts and web are not completely uniform plate-like parts
of the support frame, but contain openings, whereby material is saved. Further, the
brackets cut and bent from opposite elongated plates in accordance with the invention
can be set to overlap to a desired extent when they are fastened to each other, whereby
this overlap makes it possible to adjust the width of the support frame. The width
of the support frame can also be adjusted by altering the angle at which the brackets
extend from the plates. Since it is possible to adjust the width of the support frame
during manufacturing, the same elongated plates or the same raw material sheeting
can be used, whereby the manufacturing process can be simplified and costs saved.
BRIEF DESCRIPTION OF THE FIGURES
[0008] The invention will now be described in greater detail by means of preferred embodiments
and with reference to the attached drawings, in which
Figure 1 shows a schematic view of a plate part of an embodiment of the invention,
Figure 2 shows a schematic side view of a support frame of the present invention,
and
Figure 3 shows a schematic top view of the support frame according to Figure 2.
DETAILED DESCRIPTION OF THE INVENTION
[0009] Figure 1 shows a partial view of an elongated plate part 4 used in manufacturing
a support frame according to the present invention for wall, roof and floor structures.
Two of these plate parts 4 are used in manufacturing the support frame by joining
them together. The plate part 4 is preferably made of sheet metal with a thickness
of 0.5 to 1 mm, for instance. To increase its rigidity, the plate part 4 may be embossed
in a desired manner and with a desired pattern. According to Figure 1, the plate part
4 is profiled to increase its rigidity. In the case of Figure 1, the profiling is
done by providing folds 10 on the longitudinal edges of the plate part 4. It is also
possible to profile only one longitudinal edge of the plate part 4. It should be noted
that the profiling may be performed in a desired manner such that the resulting profiled
plate part 4 has a desired shape and rigidity properties. The width of such a plate
part 4 may be 40 to 60 mm, for instance, and the depth obtained by profiling may be
approximately 5 to 10 mm. In length, the plate parts 4 may be as required in each
case.
[0010] As shown in Figure 1, areas 6 are cut into the plate part 4 which are, however, not
entirely separated from the plate part 4, but the cuts 9 are made in such a manner
that the area 6 defined by the cuts is still attached to the plate part 4 on one of
its edges or at one or more points. The cuts may be made by any known method. The
cut area 6 may be rectangular as shown in Figure 1, or square, oblong elongated strip-like,
curved, semicircular, semielliptical, or of any other shape in such a manner that
the cut area 6 is at least at one point or on one side at least partly attached to
the plate part 4. The cuts 9 are preferably provided on the straight surface part
of the profiled plate part 4. Thus, the cut areas 6 are provided in such a manner
that they may be bent in relation to the rest of the plate part 4, whereby they extend
leaf-like outward from the surface of the plate part 4. The cut areas 6 are provided
in the plate part 4 consecutively in its longitudinal direction as shown in Figure
1. For the formation of the support frame, there are two or more of these cut areas
in each plate part. Adjacent or consecutive cut areas 6 are cut in Figure 1 in such
a manner that they may be bent in different directions in relation to the plate part
4. In other words, the top cut part in Figure 1 is bendable upward, because it is
still attached to the plate part 4 at its top edge, and the bottom cut part is bendable
downward, because it is still attached to the plate part 4 at its bottom edge. Adjacent
or consecutive cut parts may also be identical, in which case they are bendable in
the same direction in relation to the plate part 4. It should also be noted that preferably
all cut areas 6 of the plate part are similar in shape and dimensions, but in special
cases at least some of them may also be different. For instance, every second consecutive
cut area may be similar. Alternatively, the cut areas may be provided such that they
may be bent sideways to the right or left, whereby they are attached to the plate
part from either side edge. Adjacent cut areas may then also be attached to the plate
part at different side edges, in which case they may be bent in different directions.
[0011] It should be noted that the cuts can also be made at the edges of the plate parts
4, in which case notchings form at the edges when the cut areas are bent away from
the plate part. Such cuts provided at the edges may be formed at one or both edges
of the plate part.
[0012] Consecutive or adjacent cut areas 6 are preferably provided at a predefined distance
from each other in such a manner that a uniform neck 12 is formed between them. This
neck 12 forms a screw area to which a wall plate and/or surface plate to be fastened
to the plate part or support frame can be screwed or otherwise fastened.
[0013] The support frame comprises flange parts extending in its longitudinal direction
and a web extending between the flange parts. Figure 2 shows a support frame 2 according
to the present invention, which is provided by joining together two plate parts 4
according to Figure 1. In other words, the support frame 2 is made up of two elongated
plate parts 4 and 5 that are joined together. The plate parts 4 and 5 preferably extend
parallel in the longitudinal direction of the support frame 2 in such a manner that
the straight surface parts of the plate parts 4 and 5 are essentially parallel, whereby
they form the flange parts of the support frame 2. In accordance with Figure 2, the
areas cut into the first plate part 4 are bent to extend outward from the surface
of the plate part 4 so as to form brackets 6. In a similar manner, the areas cut into
the second plate part 5 are bent to extend outward from the surface of the plate part
so as to form brackets 7. The brackets 6 and 7 are herein referred to as fastening
brackets 6 and 7. In the manner stated above, the fastening brackets 6, 7 are formed
correspondingly by cutting and bending the plate parts 4, 5, whereby openings corresponding
to the fastening brackets 6, 7 remain in the plate parts 4, 5 after bending.
[0014] The fastening brackets 6, 7 may be bent to a required angle in relation to the plate
parts 4, 5, whereby the angle between the plate part 4, 5 and the fastening bracket
therein may for instance be 90° to 20°, preferably 45° to 90°. Typically, all fastening
brackets 6, 7 of the plate part 4, 5 extend from the plate part 4, 5 at the same angle.
The angle between consecutive or adjacent fastening brackets 6, 7 and the plate part
may be the same even though the consecutive or adjacent fastening brackets were bent
into different directions in relation to the plate part 4, 5 in the manner described
above. In some embodiments, the consecutive or adjacent fastening brackets 6, 7 may
also extend outward from the plate part 4, 5 at different angles.
[0015] According to Figure 2, the support frame 2 is provided by joining together two above-mentioned
plate parts 4, 5 that comprise fastening brackets 6, 7. This is done by fastening
the first fastening brackets 6 of the first plate part 4 to the second fastening brackets
7 of the second plate part 5 in such a manner that the joined first and second fastening
brackets 6, 7 extend between the first and second plate parts 4, 5. The first fastening
brackets 6 of the first plate part 4 preferably extend at the same angle from the
first plate part 4 as the second fastening brackets 7 of the second plate part 5 extend
from the second plate part 5. Thus, the first and second fastening brackets 6, 7 are
parallel between the first and second plate parts 4, 5 and they may be set to overlap
as shown in Figure 2.
[0016] Alternatively, it is possible to join together two plate parts in which the cut areas
may be bent sideways in relation to the longitudinal direction of the plate parts
to form a web. The cut and bent fastening brackets may then extend between opposite
plates from diagonal plate edges or close thereto. Consecutive joined fastening brackets
extend transverse to each other to provide a lattice structure, or parallel in which
case the fastening brackets of both plate parts extend in the same direction. The
cut and bent fastening brackets may also extend from opposite edges to opposite plate
parts or close thereto, whereby a sheath-like structure may be formed when consecutive
joined fastening brackets are provided at the edges of the plate parts or close thereto.
When joining two plate parts together, these sideways bent cut areas may be fastened
to each other to form a web. This way, the cut areas of opposite plate parts may extend
diagonally in relation to the plate parts to form a web with a lattice structure,
when the cuts in the second plate part are made in the same way. Similarly, the cuts
that have been made consecutively on the plate part edges and bent may be fastened
to each other to form a web.
[0017] The first and second fastening brackets 6, 7 are, as shown in Figure 2, set to overlap
and fastened to each other with fastening means 8. The fastening means 8 may be rivets,
screws, or other corresponding mechanical fastening means. Alternatively, the first
and second fastening brackets 6, 7 may be fastened to each other by welding using
laser, for instance.
[0018] The thus obtained support frame 2 of the invention is made up of first and second
plate parts 4, 5 that form the flange parts of the support frame 2, and joined first
and second fastening brackets 6, 7 that form the web of the support frame 2. In other
words, the web of the support frame 2 is formed by cutting strips from the flange
parts and bending the strips to extend from the flange parts, the strips being further
fastened to corresponding strips of the opposite flange part. The web is then formed
of the material of the flange parts, in which case the flange parts have openings
that correspond to the strips cut and bent from the flange parts. The web is thus
made up of consecutive bent and joined fastening brackets 6, 7 of opposite plate parts
4, 5, and the fastening together of these brackets join the plate parts 4, 5 together.
Thus, the web of the support frame 2 is formed of a cellular structure, and the web
is no longer a uniform plate, but a structure made up of consecutive plate-like bridges
connecting the first and second plate parts 4, 5 to each other. The web is thus not
uniform, but comprises openings between the fastening brackets 7, 6. The obtained
support frame 2 thus has openings in both the flange parts and web, whereby material
is saved. In other words, the web of the support frame 2 is formed from the flange
parts or plate parts by cutting and bending.
[0019] Figure 2 also shows that the arrangement of the invention makes it possible to adjust
the width D of the support frame 2 by means of the fastening brackets 6, 7. Firstly,
the width of the support frame 2 can be influenced by adjusting the bending angle
of the fastening brackets 6, 7 in relation to the plate parts 4, 5. The smaller the
angle of the fastening brackets 6, 7 in relation to the plate parts is, the narrower
a support frame 2 can be made by fastening the fastening brackets 6, 7 of the opposite
plate parts to each other. The widest width of the support frame 2 can in turn be
achieved by bending the fastening brackets 6, 7 to a 90° angle in relation to the
plate parts 4, 5. Another possible way of altering the width of the support plate
2 is to vary the overlap of the fastening brackets 6, 7 to be fastened to each other.
In other words, the longer the overlap of the fastening brackets 6 and 7 is, the smaller
is the width D of the support frame 2. On the other hand, the smaller the overlap
of the fastening brackets 6, 7 is, the wider is the support frame 2. This way, similar
plate parts can be made into very different support frames with different widths as
necessary.
[0020] Figure 3 shows the embodiment of Figures 1 and 2 from the top. Figure 3 shows that
the first and second plate parts 4, 5 are fastened to each other with the fastening
brackets 6, 7. The first fastening brackets 6 are cut into the first plate part and
bent to extend outward from the first plate part 4. Correspondingly, the second fastening
brackets 7 are cut into the second plate part 5 and bent to extend outward from the
second plate part 5. The first and second fastening brackets 6, 7 are set to overlap
in such a manner that they extend a predefined distance on top of each other. In Figure
3, the second fastening brackets 7 are set on top of the first fastening brackets
6. These overlapping fastening brackets 6, 7 are then fastened to each other with
rivets 8. In Figure 3, the longitudinal edges of the first and second plate parts
4, 5 are profiled to increase the rigidity of the plate parts 4, 5.
[0021] When manufacturing the support frames 2 of the invention for wall, roof and floor
structures, elongated even plate parts 4, 5 are first provided and cut into suitable
dimensions. After this, the plate parts 4, 5 are profiled by roll forming, for instance.
After profiling, fastening brackets 6, 7 are cut into the plate parts 4, 5 and then
bent to extend outward from the plate parts 4, 5. Next, the fastening brackets 6,
7 of the two plate parts 4, 5 are fastened to each other to form the support frame
2. It should be noted that the above-mentioned steps may also be performed in some
other alternative order, and they may also be performed consecutively or in part simultaneously
in one manufacturing apparatus. In addition, it is possible to utilize a manufacturing
apparatus that can be brought to and used at the site, which means that it is not
necessary to transport the finished support frames to the site, but they can be manufactured
there as necessary and with the required dimensions.
[0022] It is obvious to a person skilled in the art that as technology advances, the basic
idea of the invention can be implemented in many different ways. The invention and
its embodiments are thus not restricted to the above examples, but may vary within
the scope of the claims.
