[0001] The invention relates to a carrier element, which has a plurality of segments, wherein
the segments are arranged side by side in a longitudinal direction, wherein each segment
has a centre region and two side regions extending to different sides from the centre
region, wherein two adjacent segments are separated by a cut extending substantially
along the entire with of the centre region between the segments, wherein two adjacent
segments are connected by a common strip of material formed by the side region of
the two adjacent segments at a first side, wherein two adjacent segments are separated
by a side cut arranged in the side region of two adjacent segments at a second side
opposite the first side and wherein the connection between two side regions and the
separation between two side regions are altering from side to side along the longitudinal
direction from segment to segment.
[0002] Carrier elements of this kind are pre-known and used in the field of construction
of buildings, especially in the field of dry mortarless construction. The advantage
of such a carrier element is that it is quite easy to construct a round arch by bending
two adjacent segments of the carrier element relatively to another until the desired
shape of the whole carrier element is formed.
[0003] A known profile device is disclosed by document
EP 1657376. It has been found that it is sometimes complicated to ensure the uniformity of such
an arch structure. This applies as well if another non-straight structure has to be
formed for which a high degree of uniformity is desired. It depends on the skills
of the construction worker to achieve a good result.
[0004] If such a skilled worker is not available the securing of a high degree of uniformity
becomes very time consuming an expensive.
[0005] Therefore, it is an object of the present invention to propose a carrier element
according to the above mentioned kind which allows to form an arch structure or, generally
spoken, a non-straight structure, with a high degree of uniformity without the necessity
of a skilled worker and/or without a time consuming process.
[0006] The solution of this object according to the invention is characterized in that at
least one of the plurality of bores are arranged in the centre region adjacent to
the side cut between two side regions, and by bringing two of the bores of adjacent
segments in an overlapping position it becomes possible in an easy way to define an
exact angle between the axis of two adjacent segments.
[0007] Preferably, a plurality of bores is arranged in the centre region adjacent to the
side cut between two side regions; the number of bores can be 3 or 4 or even more.
[0008] A preferred embodiment is equipped with bores which are arranged mirrowed to the
cut between the centre region of two adjacent segments.
[0009] The cut between two centre regions of the segments and the side cut between two side
regions of the segments can be formed continuously.
[0010] Furthermore, the bores can be located on a circle line having its centre at the end
of the cut between two centre regions adjacent to the common strip. The bores can
be arranged equidistantly or not-equidistantly along the circle line. To use a nonius
effect in the precise angled orientation of two adjacent segments it can be provided
that the distance between two bores increases or decreases from bore to bore by a
defined amount.
[0011] A stiff construction is achieved if the centre region and the two side regions form
a U-shaped structure.
[0012] The cut between the centre regions of two adjacent segments can have a T-shaped form
in the top plan view. Furthermore, the cut between the centre regions of two adjacent
segments can have has a circle shaped form at one end. By this the bending of adjacent
segments is facilitated.
[0013] The at least one of the plurality of holes can be arranged for receiving a connection
element. The connection element is preferably a bolt or a screw.
[0014] The carrier element is preferably made from a metallic material, especially from
sheet metal with steel as basis material.
[0015] A cost efficient production of the carrier element is ensured if the carrier element
is produced by a punching process.
[0016] With the suggested concept a very easy non-straight orientation of the segments of
the carrier element can be realized with a high degree of uniformity.
[0017] In the drawings embodiments of the invention are depicted.
- Fig. 1
- shows a perspective view of a sheet metal from which the carrier element according
to the invention is formed, mainly in an unfolded state, partly in a folded state,
- Fig. 2
- shows the top plan view of a sheet metal from which the carrier element is formed,
in the left part of the figure in an unfolded, plan state, in the right part of the
figure in the folded state,
- Fig. 3
- shows a perspective view of two adjacent segments of the carrier element,
- Fig. 4
- shows the top plan view of a carrier element, formed to a bow, and
- Fig. 5
- and
- Fig. 6
- show two different perspective views of the carrier element according to fig. 4.
[0018] In fig. 1 a perspective view is depicted of a flat sheet metal from which a carrier
element 1 according to the invention is formed. The figure shows a sheet metal element
which consists of a steel material; the figure shows mainly a flat, not yet folded
state of the carrier elements while a finish folded part of the carrier element 1
is shown in the left upper part of the figure.
[0019] As can be seen in fig. 1 the carrier element 1 is basically machined by punching
of a flat strip of sheet metal. It can be seen that cuts 8, 10 and bores 11, 12 of
a certain form and magnitude are brought into the sheet metal strip. Consequently,
the production of the basis part of the carrier element 1 is quite simple and cost
efficient.
[0020] By punching cuts 8, which have a substantial T-shaped form, the following regions
are defined in the punched part: By the cuts 8 - arranged parallel to each other along
the longitudinal direction L of the sheet metal strip - segments 2 are defined which
are arranged adjacent to another. Furthermore, by the length of the cuts 8 (seen in
transversal direction perpendicular to the longitudinal direction L) a centre region
3 of each segment 2 is defined; to both sides side regions 4 and 5 abut to the centre
region 3, wherein the side regions 4 and 5 respectively are located at the sides 6
and 7 of the sheet metal strip.
[0021] After having punched the sheet metal strip according to the design shown in fig.
1 the material is bent into the shape which is depicted in the left upper region of
fig. 1, i. e. into a U-shaped configuration.
[0022] In the synopsis of figures 1 till 3 the following design of the carrier element 1
becomes apparent: The cuts 8 have - as mentioned - a T-shaped form in the top plan
view, whereby the segments 2 are defined. The orientation of the T-shaped configuration
alters from segment 2 to segment 2 as can be easily seen. From the T-bar 19 of the
T-shaped cut 8 a side cut 10 extends transversally to the longitudinal direction L
and through the whole side region 4, 5 to separate the adjacent side regions 4, 5
of two segments 2. It should be noted that not necessarily all cuts 8 have a respective
side cut 10; side cuts 10 can be limited to a certain selection of the cuts 8. The
side cuts 10 are also produced by a punching process.
[0023] While the side cuts 10 separate adjacent side regions 4, 5 of the segments 2, common
strips 9 of material are formed at the opposite side of the segments 2, i. e. at the
other side 4, 5 with respect to the longitudinal direction L. The common strips 9
connect two adjacent side regions 4, 5 in a stiff way.
[0024] With this design it becomes possible to form the segments 2 not only along a straight
line but also along a desired curve. Specifically, it becomes possible to form an
arch structure as it can be seen in figures 4 till 6.
[0025] To facilitate the forming of such a structure with a high degree of uniformity and
in an easy way the invention proposes that at least one of a plurality of bores -
is arranged in the centre region 3 adjacent to the side cut 10 between two side regions
4, 5. For purpose of illustration reference is made to fig. 2. Here, is can be seen
that near the T-bar 19 of the T-shaped cut 8 two bores 11 and 12 are punched into
the material of the sheet metal.
[0026] If two adjacent segments 2 stay in a straight orientation - as shown in fig. 3 -
the bores 11, 12 have no function.
[0027] But if a non-straight profile has to be formed by the carrier element 1 - as depicted
in the right half in fig. 2 - the purpose of the bores 11, 12 becomes apparent: Two
adjacent segments 2 are bended relatively to another so that the common strip 9 of
material has a kink 20. The side regions 4, 5 of the segments 2 at the other side
6, 7 of the segments 2 overlap a certain amount as well as the sides of the centre
regions 3 which becomes possible due to the cuts 8 and side cuts 10. Also the bores
11 come to an overlapping position which is depicted with reference numeral 18. Overlapping
of the bores 11, 12 is made possible because the bores 11, 12 are arranged along a
circle line 14 (see fig. 2) which has its centre 15 at the point where the kink 20
will be arranged.
[0028] The distance a between the bores 11, 12, 13 can be constant. Another possibility
is that the distance a varies from bore to bore - which is basically relevant if a
bigger number of holes 11, 12, 13 is used. By a difference in the distance between
the bores 11, 12, 13 if becomes possible to use the effect of a nonius (vernier scale).
[0029] So, it is now very easy to bend two adjacent segments until the bores 11 are in an
overlapping position. It should be noted that the bores can serve just as an optical
control to check if the precise desired angle of the kink 20 is reached.
[0030] It is also possible but not mandatory to insert a bolt or screw into the overlapping
bore 18 to fix two segments 2 relatively to another in the desired position.
[0031] The bending of two adjacent segments is facilitated by punching a circle shaped form
16 (see figures 1 and 2) in the end 17 of the cut 8.
[0032] With reference to figures 4 till 6 is can be seen that here three bores 11, 12, 13
are employed at the side of each segment 2 adjacent to the cut 8.
