Description
W O 97~0113 ~ PCTAEP96/05109 SET OF BUI~DING ELEMENTS FOR FRAMEWORK STRUCTURES
The subject matter of the invention i8 a set of structural element~ ~or producing supporting QtruCtUre~, having supporting bars and connecting element~ ~or connecting the end~ of the supporting bars to one S another.
The various embodiment~ of ~upportin~ ~tructure~
which can be produced from supporting bar~ by means of connecting elements have been known for ~ome time now.
Basic elements, ~or example, pyramids, can be produced from the supporting bars and connecting elements. In this case, a R~uare base area of the pyramid i8 produced from 4 ~upporting bar~, and -Q-upporting bar~ are used to form 4 side ~urfaces in the form of i~o~celes triangles. The respective ends o~ the supporting bars are held together at the tip of the pyramid by a connecting element. sasic elements of this kind can be combined to produce sup-porting structures which extend over relatively lar~e surface area~ and exhibit sufficient ~tability.
DE-OS-24 57 674 discloses a c~nnection of sup-porting bars using h~;spherical junction pieces, thisco~nection m~; ng it possible to construct supporting ~rameworkQ for scaffolding-like or skeleton-like structures. The structures not only comprise bars r~nn;n~
at right angles to one another. In this design, the junction piece provided is a hollow hemisphere in which there are formed slots which run along great circles and ~n t-'~h it is possible to insert, at various angles, ths ends of ~ o Ling bars provided with corresr~n~;n~ bolt~
and nut~ or bolt heads. Using such connecting y oove8, it is thus possible to form tetrahedral or elge cubic basic elements 40r supporting structures which are m~de up of a number o~ such basic elements.
A set of structural elements for producing supporting structures from supporting barP and junction ~ 35 pieces is disclosed in German Utility Model 88 16 884 and DE-OS-38 00 547. The cylindrical junction pieceg have slots which are distributed uniFormly over the circum~er-ence, extend radially inward from the surface and are wi~e~, in each case on a circle around the center axis W O 97~0113 PCTAEP96/05109 _ Z _ of the junction piece, to form cylindrical chambers r~l~n~ng parallel to one another. The slots and chambers serve to recei~e, with a form fit, insertion heads which are _ormed at the flat ends of ~upporting bar The insertion heads are thick~n;ngs, in the form of cylindri-cal bead~, which correspond to the length of the chamberQ
and are adapted to the cros~ section of the cham~er. They are formed by rolling in pressed-flat end~ of the tubular supporting bars. Eowever, it i8 also possible, i~or half-cylinder ~trip~ of the height of the pressed-flat regions to be rivetted on the latter or for hemispherical or oval stamped sections to be pro~ided in these region~, on both sides in each case, such that a bead with circular cross ~QCtion i5 produced at the end of the pressed-flat supporting bars.
Despite the form fit, there is a considerable amount of play in the positioning of the supporting bars with respect to the iunction pieces, on account of the smaller diameter of the beads with respect to the cha~ber diameters and of the thickness of the pressed-flat regions in comparigon with the width of the slots, provided that the two endg of a supporting bar are not ~onn~ted to other junction pieces.
The ob~ect of the present invention is to improve 2~ further the abovedescribed, known junction pieces and insertion heads.
This object is achieved by a set of structural elements for pro~c;~g gupporting structures, having supporting bars and cylindrical connecting elements for insertion heads provided on the end sides of the support-ing bars, the co~ecting elements being provided with a plurality of slots which are open on one side and extend, parallel to one another and to the axis of the cylindri-cal connecting elements, from the surface to the center, ~nd the slots each being wi~ , at a distance _rom the radial ends of the same, to form chr ers for recei~ing the i~sertion heads, and the ingertion heads being formed at the flat endg of the gupporting bars, wherein, at a distance _orm the end edgeg of the flat ends o~ the W O 97~0113 PCT~EP96/05109 supporting bars, at least two parallel slits are provided at an angle of 90~ with respect to the end edge, and, in order to ~orm the insertion head~, in each case one bead r~nning parallel to the end edge is formed in the strips produced by the slit~, and the beads of adjacent strips are respectively ~ormed on mutually opposite sides, with the result that a cross sectionally ~nn~ r thickening with an outer circumference which corresponds to the cross section of the chamber in the slot~ o$ the connecting elements i8 i~ormed in the region of the flat ends of the supporting bar~, parallel to the end side, beside a continuous border strip.
The chambers in the slots of the connecting elements may ha~e a circular or oval cross section.
Accordingly, the ~nnn~ thic~en;ngs o~ the insertion heads have a corresron~;ng circular or o~al cross section.
Preferably 3 to 7 strips are formed at a distance ~rom the end edge and, thereafter, 3 to 7 beads are produced in the form of hemispherical or oval stamped ~ections which are re~pecti~ely arranged on mutually opposite sides 80 as to form a bead with an a~ o~mately circular or oval cross section. Once the boadQ have been formed, a continuous border strip ~ ~;n~ on the end edge of the flat ends, and this engages in that part of the slots which extends r~ ly inward in the connecting element from the chP~hers.
In order to strengthen the flat end region with the insertion heads with respect to the supporting bars, one or more parallel beads may be ~ormed, at an angle of 90~ with respect to the end edge of the flat ends of the supporting bars, in the f~at region between the thicken-ing with annular cross section and that end of the flat region which is remote ~rom the end side.
~5 The center axis of the ~nn~ thickening is ~paced apart from the end o~ the supporting bars, a continuous border strip being ~ormed in the process, by a distance. This distance is slightly smaller than the distance of the center axis of the chambers from the CA 02237020 l998-05-07 W O 97/20113 PCT~EP96/05109 -- 4 _ inner ends of the ~lots in the connecting e}ement~.
In order to reinforce the form-fit engagement of the insertion heads in the chambers o~ the connecting elements, a pin may be arranged in the duct, formed by the beads, of the Ann~ ~ thick~n;ng.
For the purpose of receiving the insertion heads, the connecting elements have preferably eight ~lots, with chambers, arranged in a rotationally symmetrical m~nn~
with respect to the axis of the connecting elements.
The connecting elements are profile parts which are cut to length and have continuous slots and chamber3.
The r~h~mhe~ 8 and 810t8 can be closed by dis}cs which can be fastened, on both sides, on the end faces o~ the profile parts.
The fast~n;ng can take place in that the con-necting elements have a continuous bore in the center.
This so-called central bore may have an int~nn~l thread at lQast in the end regions, in the vicinity o~ the end ~aceB .
In order to f~rm supporting structures, it is preferred to have supporting bars arranged in dif~erent ways w~th r~spect to the longit~;n~l axis of the ~upporting bars. For the supporting bars which are to be arranged horizontally or vertically in the supporting structures, the insertion heads are arranged such that the ~nn~ r thick~nings, formed from beads, with circular or oval cross section run, in the two end regions of the supporting bars, at an angle of 90~ with respect to the longit~;n~l axis of the supporting bar~.
In another ~ 'o~; ~ t of the ~o.Ling bars, in which case the latter are to be connected to other ~upporting bars at an angle other than 90~ with respect to the longit--~;n~l axis, the insertion heads are formed at d~ erent angles with respect to the longitn~in~l axis 3~ of the supportiny bars. In the ca~e of these so-called diagonal bars, the ~nnlll~ thick~n;ngs, ~ormed _rom the beadn, w~th circular or oval cross section run, in the two end regions of the supporting bars, parallel to one another and at an angle a of S5~ to 45~ with re~pect to -W O 97~0113 PCTAEP96/OS109 the longit~ l axi~ of the supporting bars.
The connecting e}ements may be produced from metal or plastic. Preferred metals are steel, al--min-~m or other corrosion-resistant metal alloy~.
If the connecting elements are produced from ~ plaQtic, impact-resi~tant polymers, which may optionally be reinforced by the insertion of fiber~, are preferred.
Suitable polymers are impact-resistant grades of poly-styrene, polycarbonates and ABS terpolymers.
Metals such as al~m;nl~m or steel are preferred for the supporting bars.
In ~rder to permit simple insertion of the insertion heads into the ~necting elements, tolerances are set at the production stage uuch that the diameter or 1~ outer circumference of the ~nn~ r beads of the insertion head8 i8 always 8 ~ t smaller than the diameter or the circumference of the ch~ers in the conne~ting slots.
The flat end regions of the supporting bars are esch ~; n'S~t th;rlrle~ than the thickness of the slots in the ao co~necting elements. The differences in thickness may be in the range from a few tenths of a millimeter up to one millimeter, and in some circumstanceg even up to two millimeters. The length and diameter of the supporting bars are selected such that the desired connecting strength of the supporting bars is achieved. If tubes are u~ed as ~o~Ling bars, the wall thickness is selected correspo~d;~g}y. In such a cage, the flat end regions can be produced simply by pressing the tubes flat.
The in~ention will now be described in more detail with reference to the figures, in which:
Figure 1 shows a cross section through a connect-ing element, Figure 2 shows a longit~ l section of a ~upporting bar, Figure 3 shows the supporting bar of Figure 2 turned through an angle of 90~ around the longit~
axis, Figure 4 shows a section along line A-B of Figure 3, W O 97~0113 PCT/EP96/05109 ~ 6 --Figure 5 ~hows a section alony line C-D of Figure 3, Figure 6 ~hows a longit~ n~- ~ection through another ~hodiment of a ~upporting bar, which may be used as a so-called diagonal bar in supporting ~tructures, Figure 7 shows the supporting bar represented in Figure 6 turned through 90~ along the longit~;n~l axis, and Figure 8 shows a section along line A-B o_ the Figure 7.
Figure 1 Rhow~ a cros~ section through the connecting element lo The cylindrical connecting elements 1 have the cross section repre~ented and are ~Y;~lly a~ long as the width of the flat ends o~ the supporting bars which are to be c~nn~cted to one another by the connectlng e}ements 1. A plurality of ~lots 2, 2a which are open on one side and are distributed in a rotationally ~ymmetrical ~nne~
extend from the surface to the center oi the cylinder, from onQ end face to the other end face of said cylinder.
Eight slots 2 are provided in the example of Figure 1.
The width of the slots 2 is Q~ l,at larger than the thickness of the flat ends of the supporting bars. The slots 2 are each widened, at a distance from the radial ends o_ the same, to ~orm approximately cylindrical ~hr 'cr~ 3 which extend, parallel to the axis of the cy~ rom one end face to the other end face. The center axes of the ~ crs 3 are preferably located on a circle around the center of the cylindrical connecting element 1. ~c-,~vGr, it is also possible to form different cornecting elements 1 in which the center axe~ of the chambers are located on circles with ~lightly dif~erent diametern, depen~;n~ on whether the connecting element i8 in~n~ to be subiected to tensile or compressi~e lo~;n~. If it is to be subjected to tensil~ lo~n~, the diameter should be smaller than for a connecting element w~ch is subiected to compressive lo~ n~ . The diameter of the ~hr ~crs 3 corresponds a~.~ximately to the ext~- nn l diameter o~ the thick~;ng with ~n~ ~ cross W O 97~0113 PCTAEP96/05109 ~ 7 --section formed in the end region of the supporting bars.
The diameters correspond to one another such that the insertion heads of the supporting bars can easily be inserted into the slots 2, provided with cha~ers 3, o~
5 the connecting element~ 1, but nevertheless a certain form fit is achieved which is sufficient to retain the supporting ~ars on the connecting element 1. Ext~n~i the slots 2, 2a in the radial direction beyond the chambers 3, the ends of the slots ne~ertheless being spaced apart form the center axis of the conn~ting elements 1 by such a distance that the strength of the elements 1 is not advergely affected, has the advantage o$ corresr~;~yly formed insertion heads 6 on the supportiny bars being able to engage as ~ar as these slot regions 2a and of better ~ n~e of the insertion heads in the connecting elementg 1 being achieved.
The connecting elements 1 may have a central bore 4. There may be an int~ thread, preferably starting _rom the end _aces, over part of the central bore 4, but not throughout said central bore 4. The thread serves for the engagement o~ screwg in order for it to be possible to ~asten, on the end faceg of the connecting elements 1, covering plates which cloge the endg o~ the slots and of the ~-hr crs 3 at the end faces of the connecting elements.
The connecting elementg 1 may be produced from drawn metal pro~ileg, by cutting the latter to the desired }ength. The height of the cylindrical connecting elements 1 coincides with the width of the flat ends of the ~G ~ Ling bars.
Figure 2 showg a section of a supporting bar 5 with insertion heads 6, formed in the region of the two flat ends, for engagement in 810ts, provided with cham-bers, of the connecting elementg. In order to form the insertion heads 6, at leagt two, preferably up to six, parallel slits are provided at the f}at ends of the ~olLing bars 5, at a digtance from the end edges, at an angle of 90~ with respect to the end edge, this resu}ting in at least three, pre_erably up to soven, WO 97~0113 PCT~EP96/05109 strips 9 located one beside the other in the region of the flat ends, at a distance from the end edges. In each case one bead 7 r~nn; ng parallel to the end side is made in the ~3trips 9, at a distance from the end edges.
The hemispherical or oval stamped ~;ections formed by the beads 7 are respectively formed on mutually opposite side~3 in adjacent l:trips 9 in order to form, parallel to the end side of the flat ends of the support-ing bars 5, a cross ~3ectionally zlnn~ lAr thi~k~n;ng whose outer circumference corresponds with the inner circum-ference of the chambers in the slots of the connecting ~lement~:. The ;-nn~ n thi~ken~ng, which extends o~rer the width of the flat ends o~ the supporting bars 5, has an outer surface which is interrupted in each stxip on one side. Once the insertion head 6 has been inserted into a nn~t~ting element, it is possible, in order to reinforce the form-fit engagement, to insert a pin (not shown) into the duct 8 formed by the beads 7, the external diameter of this pin being slightly larger than the inte~
diameter of the duct 8.
The continuous border strip 10 of the insertion heads 6 which Y- ~; n ~ in each case on the end edges of the flat ends of the supporting bars 5 engages in the region between the chamberE~ 3 and the inner ends of the 2S slots 2 when the insertion heads 6 are inserted into the slots 2a of the conn~ting elements.
F~gure 3 shows, in plan ~riew, the supporting bar 5 shown in Figure 2 turned through 90~ around the longi-t~ n~l axis. The insertion heads 6 are formed at both ends. It i8 pos~ible to see the arrangement of the bQads formed from the strips 9 in the region ad~oining the cont~n~ Q border strip 10. In the case of this ~n-~o~;-ment of the supporting bars 5, which are used as 80-called two-~i -n~ional bars in supporting gtructures, the 35 cross sectionally s-nn-ll~n thi~k~n~ng rung at an angle of 90~ with re~pect to the longitn~;n~l axis of the support-ing bars 5. In order to strengthen the flat ends of the ~uyy~ Ling bars 5, one or more beads 11 r?~nn;n~ at an angle of 90~ with respect to the end edge o~ the support-W O 97/20113 PCT~EP96/05109 _ 9 _ ing }:ars 5 may be provided in the region of the flat ends, between the thick~n; ng with annular cros~ section and that end of the Elat region which i~: remote from the end edge. In the case of the ~upporting bar 5 shown in 5 Figure 3, these beads ll run parallel to the longit~3in~l axis of the supporting bar 5.
Figure 4 i8 a section along line A-B of Fig~ure 3, for the purpose of illustrating the formation of the beads 7 o~ adjacent strips 9 respectively on mutually 10 opposite sides.
Figure 5 is a section along line C-D of Figure 3 and shows the })eads 11 for E;treng~h~n;n~ this region of the flat ends.
Figure 6 show~ a section through another : ' -';-15 ment of a supporting bar 5, which is int~nr~ to be us~das a so-called three~ Qional diagonal bar in support-ing structures. In the case of this embo~;m~r~t, the axes of the insertion heads 6 run at an angle cY other than 90~
with respect to the longit"~;n~l axis of the supporting 20 bar 5, a~ can be seen from Figure 7.
In the same T-nn~ a~ in Figure 2, the insertion head6 6 have beads 7 which are formed, in individual sections (strips 9), in mutually opposite directions, to form the beads or the thiclr~n;ng with ~nn~ cross 25 section and duct 8. Once the beads 7 ha~re been formed, a cont~n~o~Q border strip 10 still ~ -;nQ in each case on the end edges of the flat ends of the supporting bar 5.
Figure 7 shows the supporting bar 5 represented in Figure 6 turned through 90~ around the longit~;nS~l 30 axis, 80 that it is posgible to see the insertion heads 6 arranged parallel to one another at the two ends of the supporting bar 5 as well as their aligDment with respect to the longit~;n~l axig of the gupporting bar. The angle c~ of the longit~ n~l axis of the insertion heads, in 35 particular of the this~k~n;ng, formed from the beads 7, with ~nn~ ~ cross section, may be ~rom 55 to 45~ with respect to the longi~ l axig of the supporting bar 5, in thQ example shown it is 33~.

Figure 8 i8 a section along A-B of Figure 7 and ~hows the formation of the beads 7 on mutually opposite ~ides for adjacent strips 9.
The supporting bars 5 represented in Figures 2 to 8 are preferably produced from tube~ whose respecti~e end regions have been pressed flat in order to be able to form the inE~ertion heads 6.

In order to reinforce the form-fit engagement of the insertion heads in the chambers o~ the connecting elements, a pin may be arranged in the duct, formed by the beads, of the Ann~ ~ thick~n;ng.
For the purpose of receiving the insertion heads, the connecting elements have preferably eight ~lots, with chambers, arranged in a rotationally symmetrical m~nn~
with respect to the axis of the connecting elements.
The connecting elements are profile parts which are cut to length and have continuous slots and chamber3.
The r~h~mhe~ 8 and 810t8 can be closed by dis}cs which can be fastened, on both sides, on the end faces o~ the profile parts.
The fast~n;ng can take place in that the con-necting elements have a continuous bore in the center.
This so-called central bore may have an int~nn~l thread at lQast in the end regions, in the vicinity o~ the end ~aceB .
In order to f~rm supporting structures, it is preferred to have supporting bars arranged in dif~erent ways w~th r~spect to the longit~;n~l axis of the ~upporting bars. For the supporting bars which are to be arranged horizontally or vertically in the supporting structures, the insertion heads are arranged such that the ~nn~ r thick~nings, formed from beads, with circular or oval cross section run, in the two end regions of the supporting bars, at an angle of 90~ with respect to the longit~;n~l axis of the supporting bar~.
In another ~ 'o~; ~ t of the ~o.Ling bars, in which case the latter are to be connected to other ~upporting bars at an angle other than 90~ with respect to the longit--~;n~l axis, the insertion heads are formed at d~ erent angles with respect to the longitn~in~l axis 3~ of the supportiny bars. In the ca~e of these so-called diagonal bars, the ~nnlll~ thick~n;ngs, ~ormed _rom the beadn, w~th circular or oval cross section run, in the two end regions of the supporting bars, parallel to one another and at an angle a of S5~ to 45~ with re~pect to -W O 97~0113 PCTAEP96/OS109 the longit~ l axi~ of the supporting bars.
The connecting e}ements may be produced from metal or plastic. Preferred metals are steel, al--min-~m or other corrosion-resistant metal alloy~.
If the connecting elements are produced from ~ plaQtic, impact-resi~tant polymers, which may optionally be reinforced by the insertion of fiber~, are preferred.
Suitable polymers are impact-resistant grades of poly-styrene, polycarbonates and ABS terpolymers.
Metals such as al~m;nl~m or steel are preferred for the supporting bars.
In ~rder to permit simple insertion of the insertion heads into the ~necting elements, tolerances are set at the production stage uuch that the diameter or 1~ outer circumference of the ~nn~ r beads of the insertion head8 i8 always 8 ~ t smaller than the diameter or the circumference of the ch~ers in the conne~ting slots.
The flat end regions of the supporting bars are esch ~; n'S~t th;rlrle~ than the thickness of the slots in the ao co~necting elements. The differences in thickness may be in the range from a few tenths of a millimeter up to one millimeter, and in some circumstanceg even up to two millimeters. The length and diameter of the supporting bars are selected such that the desired connecting strength of the supporting bars is achieved. If tubes are u~ed as ~o~Ling bars, the wall thickness is selected correspo~d;~g}y. In such a cage, the flat end regions can be produced simply by pressing the tubes flat.
The in~ention will now be described in more detail with reference to the figures, in which:
Figure 1 shows a cross section through a connect-ing element, Figure 2 shows a longit~ l section of a ~upporting bar, Figure 3 shows the supporting bar of Figure 2 turned through an angle of 90~ around the longit~
axis, Figure 4 shows a section along line A-B of Figure 3, W O 97~0113 PCT/EP96/05109 ~ 6 --Figure 5 ~hows a section alony line C-D of Figure 3, Figure 6 ~hows a longit~ n~- ~ection through another ~hodiment of a ~upporting bar, which may be used as a so-called diagonal bar in supporting ~tructures, Figure 7 shows the supporting bar represented in Figure 6 turned through 90~ along the longit~;n~l axis, and Figure 8 shows a section along line A-B o_ the Figure 7.
Figure 1 Rhow~ a cros~ section through the connecting element lo The cylindrical connecting elements 1 have the cross section repre~ented and are ~Y;~lly a~ long as the width of the flat ends o~ the supporting bars which are to be c~nn~cted to one another by the connectlng e}ements 1. A plurality of ~lots 2, 2a which are open on one side and are distributed in a rotationally ~ymmetrical ~nne~
extend from the surface to the center oi the cylinder, from onQ end face to the other end face of said cylinder.
Eight slots 2 are provided in the example of Figure 1.
The width of the slots 2 is Q~ l,at larger than the thickness of the flat ends of the supporting bars. The slots 2 are each widened, at a distance from the radial ends o_ the same, to ~orm approximately cylindrical ~hr 'cr~ 3 which extend, parallel to the axis of the cy~ rom one end face to the other end face. The center axes of the ~ crs 3 are preferably located on a circle around the center of the cylindrical connecting element 1. ~c-,~vGr, it is also possible to form different cornecting elements 1 in which the center axe~ of the chambers are located on circles with ~lightly dif~erent diametern, depen~;n~ on whether the connecting element i8 in~n~ to be subiected to tensile or compressi~e lo~;n~. If it is to be subjected to tensil~ lo~n~, the diameter should be smaller than for a connecting element w~ch is subiected to compressive lo~ n~ . The diameter of the ~hr ~crs 3 corresponds a~.~ximately to the ext~- nn l diameter o~ the thick~;ng with ~n~ ~ cross W O 97~0113 PCTAEP96/05109 ~ 7 --section formed in the end region of the supporting bars.
The diameters correspond to one another such that the insertion heads of the supporting bars can easily be inserted into the slots 2, provided with cha~ers 3, o~
5 the connecting element~ 1, but nevertheless a certain form fit is achieved which is sufficient to retain the supporting ~ars on the connecting element 1. Ext~n~i the slots 2, 2a in the radial direction beyond the chambers 3, the ends of the slots ne~ertheless being spaced apart form the center axis of the conn~ting elements 1 by such a distance that the strength of the elements 1 is not advergely affected, has the advantage o$ corresr~;~yly formed insertion heads 6 on the supportiny bars being able to engage as ~ar as these slot regions 2a and of better ~ n~e of the insertion heads in the connecting elementg 1 being achieved.
The connecting elements 1 may have a central bore 4. There may be an int~ thread, preferably starting _rom the end _aces, over part of the central bore 4, but not throughout said central bore 4. The thread serves for the engagement o~ screwg in order for it to be possible to ~asten, on the end faceg of the connecting elements 1, covering plates which cloge the endg o~ the slots and of the ~-hr crs 3 at the end faces of the connecting elements.
The connecting elementg 1 may be produced from drawn metal pro~ileg, by cutting the latter to the desired }ength. The height of the cylindrical connecting elements 1 coincides with the width of the flat ends of the ~G ~ Ling bars.
Figure 2 showg a section of a supporting bar 5 with insertion heads 6, formed in the region of the two flat ends, for engagement in 810ts, provided with cham-bers, of the connecting elementg. In order to form the insertion heads 6, at leagt two, preferably up to six, parallel slits are provided at the f}at ends of the ~olLing bars 5, at a digtance from the end edges, at an angle of 90~ with respect to the end edge, this resu}ting in at least three, pre_erably up to soven, WO 97~0113 PCT~EP96/05109 strips 9 located one beside the other in the region of the flat ends, at a distance from the end edges. In each case one bead 7 r~nn; ng parallel to the end side is made in the ~3trips 9, at a distance from the end edges.
The hemispherical or oval stamped ~;ections formed by the beads 7 are respectively formed on mutually opposite side~3 in adjacent l:trips 9 in order to form, parallel to the end side of the flat ends of the support-ing bars 5, a cross ~3ectionally zlnn~ lAr thi~k~n;ng whose outer circumference corresponds with the inner circum-ference of the chambers in the slots of the connecting ~lement~:. The ;-nn~ n thi~ken~ng, which extends o~rer the width of the flat ends o~ the supporting bars 5, has an outer surface which is interrupted in each stxip on one side. Once the insertion head 6 has been inserted into a nn~t~ting element, it is possible, in order to reinforce the form-fit engagement, to insert a pin (not shown) into the duct 8 formed by the beads 7, the external diameter of this pin being slightly larger than the inte~
diameter of the duct 8.
The continuous border strip 10 of the insertion heads 6 which Y- ~; n ~ in each case on the end edges of the flat ends of the supporting bars 5 engages in the region between the chamberE~ 3 and the inner ends of the 2S slots 2 when the insertion heads 6 are inserted into the slots 2a of the conn~ting elements.
F~gure 3 shows, in plan ~riew, the supporting bar 5 shown in Figure 2 turned through 90~ around the longi-t~ n~l axis. The insertion heads 6 are formed at both ends. It i8 pos~ible to see the arrangement of the bQads formed from the strips 9 in the region ad~oining the cont~n~ Q border strip 10. In the case of this ~n-~o~;-ment of the supporting bars 5, which are used as 80-called two-~i -n~ional bars in supporting gtructures, the 35 cross sectionally s-nn-ll~n thi~k~n~ng rung at an angle of 90~ with re~pect to the longitn~;n~l axis of the support-ing bars 5. In order to strengthen the flat ends of the ~uyy~ Ling bars 5, one or more beads 11 r?~nn;n~ at an angle of 90~ with respect to the end edge o~ the support-W O 97/20113 PCT~EP96/05109 _ 9 _ ing }:ars 5 may be provided in the region of the flat ends, between the thick~n; ng with annular cros~ section and that end of the Elat region which i~: remote from the end edge. In the case of the ~upporting bar 5 shown in 5 Figure 3, these beads ll run parallel to the longit~3in~l axis of the supporting bar 5.
Figure 4 i8 a section along line A-B of Fig~ure 3, for the purpose of illustrating the formation of the beads 7 o~ adjacent strips 9 respectively on mutually 10 opposite sides.
Figure 5 is a section along line C-D of Figure 3 and shows the })eads 11 for E;treng~h~n;n~ this region of the flat ends.
Figure 6 show~ a section through another : ' -';-15 ment of a supporting bar 5, which is int~nr~ to be us~das a so-called three~ Qional diagonal bar in support-ing structures. In the case of this embo~;m~r~t, the axes of the insertion heads 6 run at an angle cY other than 90~
with respect to the longit"~;n~l axis of the supporting 20 bar 5, a~ can be seen from Figure 7.
In the same T-nn~ a~ in Figure 2, the insertion head6 6 have beads 7 which are formed, in individual sections (strips 9), in mutually opposite directions, to form the beads or the thiclr~n;ng with ~nn~ cross 25 section and duct 8. Once the beads 7 ha~re been formed, a cont~n~o~Q border strip 10 still ~ -;nQ in each case on the end edges of the flat ends of the supporting bar 5.
Figure 7 shows the supporting bar 5 represented in Figure 6 turned through 90~ around the longit~;nS~l 30 axis, 80 that it is posgible to see the insertion heads 6 arranged parallel to one another at the two ends of the supporting bar 5 as well as their aligDment with respect to the longit~;n~l axig of the gupporting bar. The angle c~ of the longit~ n~l axis of the insertion heads, in 35 particular of the this~k~n;ng, formed from the beads 7, with ~nn~ ~ cross section, may be ~rom 55 to 45~ with respect to the longi~ l axig of the supporting bar 5, in thQ example shown it is 33~.

Figure 7 represents an embodiment of a supporting bar 5 in which the flat end region i~ likewise ~trength-ened by beads 11 between the bead 7 and that end of the flat ends which i8 remote from the end edge.
Figure 8 i8 a section along A-B of Figure 7 and ~hows the formation of the beads 7 on mutually opposite ~ides for adjacent strips 9.
The supporting bars 5 represented in Figures 2 to 8 are preferably produced from tube~ whose respecti~e end regions have been pressed flat in order to be able to form the inE~ertion heads 6. However, it i5 also possible, in principle, to produce ~o ~ing bars with flat end regions and with insertion headg from solid material.
