Technical field
[0001] The present invention relates to a construction profile for dry construction of walls,
partition walls, suspended ceilings and for fixing sanitary appliances, which comprises
a hollow longitudinal body from shaped sheet metal with connected edges of the sheet
metal, which comprises a dovetail projection on each of its lateral sides, defined
by longitudinal mounting embossed depressions located at the corners of the forming
four-sided shape of the construction profile.
Background art
[0002] Systems for dry construction of walls, partition walls, suspended ceilings and for
fixing sanitary appliances ceilings are available on the market from many manufacturers.
These dry construction systems are also used for the construction of walls and partitions
intended for fixing sanitary appliances, such as toilet modules, installation frames
for wash basins, bidets, urinals and other sanitary appliances.
[0003] An important component for these construction systems are longitudinal metal construction
profiles, usually produced by successive rolling of galvanized sheet metal followed
by longitudinal welding. These construction profiles are usually approximately square
in cross-section and are provided with longitudinal mounting grooves of various shapes
at the corners. Connecting elements, such as corner couplings, mounting feet, etc.,
are accordingly adapted to the shape and size of these grooves.
[0004] An exemplary embodiment of the construction profile according to background art is
shown in Fig. 1, showing a cross-section through a known construction profile, which
has a square basic cross-section, wherein it is formed from sheet metal
1 and provided at the corners
2 with longitudinal mounting embossed depressions 3 with a bottom 30 having a semi-circular
cross-section or having the shape of a longitudinally divided cylinder half.
[0005] The disadvantages of known construction profiles consist in the necessity of longitudinal
welding of the sheet metal forming the construction profile, which results in increasing
the negative impact on the environment, requires air filtration, produces toxic fumes,
consumes a lot of energy and generates a large amount of heat, which additionally
negatively affects the material characteristics of the sheet metal constituting the
construction profile. As a result of the welding, it is also necessary to subsequently
clean the weld area and to ensure the protection of the weld area against corrosion,
which further increases the economic and environmental burden arising from the production
of known construction profiles. Another drawback of the background art is also the
presence of only a short section Δ
ST (see Fig. 1 - background art) on the front part of the side walls of the individual
embossed corner longitudinal mounting depressions. For certain applications, it also
appears that it would be necessary for the construction profile to exhibit higher
torsional rigidity and better resistance to buckling.
[0006] The object of the invention is to eliminate or at least reduce at least some of the
disadvantages of the background art.
Principle of the invention
[0007] The object of the invention is achieved by a construction profile for dry construction
of walls, partition walls, suspended ceilings and for fixing sanitary appliances,
whose principle consists in that the edges of the sheet metal are connected by a longitudinal
pressed closure.
[0008] The advantage of this solution is only the use of mechanical methods of production
without the use of welding and other similar methods of joining sheets, thereby reducing
the ecological burden and energy consumption of the production. In addition, it is
not necessary to solve the problem of protecting the sheet metal edges from corrosion.
Moreover, the use of a longitudinal pressed closure creates an additional strengthening
element that improves the resistance of the construction profile in torsion and buckling.
In combination with the features of preferred embodiments which are the subject of
the dependent patent claims, a further improvement of not only in the form strength
of the construction profile is achieved, but also in the increase of the clamping
areas on the dovetail projections for fastening couplings, support feet, etc., thereby
improving the usability of systems for dry construction.
Description of drawings
[0009] The invention is schematically represented in a drawing, wherein Fig. 1 shows a cross-section
through the construction profile known from the background art, Fig. 2 shows a cross-section
through the construction profile according to the present invention and Fig. 3 shows
a spatial view of the construction profile according to the invention.
Examples of embodiment
[0010] The invention will be described with reference to an exemplary embodiment of a construction
profile for dry construction of walls, partition walls, suspended ceilings and for
fixing sanitary appliances.
[0011] The construction profile is formed by a spatial body from shaped sheet metal 1. The
construction profile has a substantially square basic cross-section, as shown in Fig.
2 by means of corners
10 of the forming four-sided shape, which is here, for example, a square, indicated
in Fig. 2 by a dashed line.
[0012] The corners
10 of the forming square indicated in Fig. 2 by a dashed line are pressed diagonally
relative to the forming square in the V direction inside the profile with respect
to the centre S of the profile in the form of longitudinal mounting embossed depressions
3.
[0013] The longitudinal mounting embossed depressions 3 have a rounded bottom 30 and a pair
of mutually opposing plane walls
31. The plane walls
31 connect to the rounded bottom
30 with a transition arc
32.
[0014] Preferably, the radius
R32 of the transition arcs
32 is 3 times to 8 times smaller than the radius
R30 of the rounded bottom
30. Preferably, the depth
H3 of the longitudinal mounting embossed depressions
3 is only by 10 to 20 % smaller than the width
S3 of the longitudinal mounting embossed depressions
3. The length
ΔAP of the plane walls
31 in the
V direction from the circumference
O of the construction profile to the centre
S of the construction profile is 40 to 70 % of the depth
H3 of the longitudinal mounting embossed depressions
3.
[0015] The construction profile further comprises lateral sides
33 defined by the longitudinal mounting embossed depressions
3, whereby these lateral sides
33 of the construction profile together with adjacent plane walls
31 of the longitudinal mounting embossed depressions
3 form a dovetail projection
34, which widens in the direction from the centre
S of the construction profile to the outer edge of the construction profile. In a preferred
embodiment, the lateral sides
33 of the construction profile are provided with longitudinal auxiliary embossed depressions
5, which can advantageously be created already within the rolling process of the construction
profile from a strip of sheet metal
1, e.g., galvanized steel sheet, or another suitable material. In the exemplary embodiment
shown, the longitudinal auxiliary embossed depressions
5 have a rounded cross-sectional shape and have a depth of half the thickness of the
wall of the construction profile.
[0016] In the exemplary embodiment shown, the bottom
30 of one longitudinal mounting embossed depression
3 is formed by folding and pressing the edges
11 of the sheet
1 together, thereby joining the edges
11 of the sheet metal
1 together, to form a longitudinal pressed closure
4 which closes the construction profile without welding or otherwise joining the sheet
1. In the embodiment shown, the mutual folding and pressing of the edges
11 of the sheet metal
1 is at least double.
[0017] To increase the longitudinal and transverse rigidity of the longitudinal pressed
closure
4, the longitudinal pressed closure
4 is provided with a row of embossed spot depressions
40 arranged one behind the other, in the exemplary embodiment shown, situated along
the entire length of the longitudinal pressed closure
4. In the embodiment shown, the embossed spot depressions 4
0 have substantially a conical shape and their longitudinal axis is perpendicular to
the outer surface of the longitudinal pressed closure
4, i.e., it is directed towards the centre
S of the construction profile. With the aid of the embossed spot depressions
40 further deformation of the individual mutually folded and pressed edges
11 of sheet metal
1 is achieved and the mechanical strength of the longitudinal pressed closure
4. Is ensured. The embossed spot depressions
40 are distributed along the length of the longitudinal pressed closure
4 at mutual intervals
Δ40, for example here in the range from 5 mm to 25 mm.
[0018] In an unillustrated exemplary embodiment, the longitudinal pressed closure
4 with optional embossed spot depressions
40 is situated in another part of the circumference
O of the construction profile, e.g., in the surface of one lateral side
33 of the construction profile etc. Also in this embodiment, the longitudinal pressed
closure
4 with optional embossed spot depressions
40 is preferably formed by at least double mutual folding and pressing of the edges
11 of the sheet metal
1.
[0019] The construction profile is produced in a required length, wherein if smaller lengths
are required, the construction profile can be cut with the usual tools, e.g., by means
of a hand-held or electrical saw, etc.
Industrial applicability
[0020] The present invention is applicable in construction production for dry construction
of walls, partition walls, suspended ceilings and for fixing sanitary appliances,
such as WC modules, wash basins, bidets, urinals and other sanitary appliances.
