Abstract
Platform flooring for scaffolding should be designed so that it is as light as possible, can be produced from only a few components, is effective in use and can be securely assembled. In addition, its width should be variable. The invention calls for the platform flooring to be made of extruded-drawn hollow sections (1) which are connected to each other along the edges by a groove-and-tongue joint (11, 14). Also included in the system are hollow-section edging sections (1', 1") which make a specially designed support section unnecessary.
Description
F~LE, ~t~ THIS ~ ENDE~
IE~TRA.~ .TION 2 1 9 1 ~ 8 1 PLATFoRM FICORING FOR SCAFF01DING
The invention relates to a platform for sca~foldings, in p~rticular scaffoldings for the construction industry or the like, whereby the platform ls ~as~mhlP~ out of one support fr~me forming its longitudinal sides and its L~urlDv~r~ side6 perpendic~lar thereto, and defines and locks a flooring serving as a treading surface of the platform, and at least two one-piece hollow-sectlon bars, which are r~le~qably connected ~ith one another at their longitudinal sides to form the flooring, whereby the hollow-section bars are constructed as closed extrusions, the side surfaces of uhich abut one another and are parallel with the longitudinal sides of the support frame, the side surfaces have a continuous groove parallel with the side surface on the one side of the respective hollow-section bar, and an elastic tongue ~ ntarily formed with respect to the groove on it~
other side. ~wo adjacent hollow-sectlon bars can bc connected with one another by the groove of the one hollow-section bar receiving the elastic tongue of the other hollo~-section bar therein. Furthermore, the longitudinal sides of ~he support frane are also formed by a similarly connectable hollow-section bar, which on its side - for~lng the outer boundary of the support fra~e - has a side surface of any desired design, pre~erably of A smooth design, however, it is equipped on the respective other side surface facing an adjacent hollow-section bar with a groove or an elastic tongue.
F~Ul~ ~, the tr~nsverse sides of the platform are each provided with a support section, on whieh the flooring rests and whioh is used to fasten the platform to the l inln~J scaffolding.
A plat~orm for a scaffolding or the like Ls already 3~ known from the Off~nl~r~ngssrh~ift DE 43 23 381 Al. The hollow-section bars are recessed over the entire length and are r~o~,~ shaped such that they can, using these 2! 91 881 recesses, he nested into one another. ~ single section is suf~icient in order to assemble - together with ~itting head pieces - one complete platform. Beads are provided, which provide inherent stability and provide for the aonn~ct;nn of adjacent hollow-section bars.
~ owever, ths known arrangement requires th~t the n~CsAry inherent ~tability i~ created during assembly in such a manner that the ad~acent hollo~-section bars are riveted together because otherwise the vall th;~ csec woUld have had to be significantly increased due to the continuous recesses in the participating S~r~ i nn~ . The beads are t~l~uuyhuuL inwardly directed in order to enable sultable lockings of adjacent hollow-section bars so that they cannot contribute to st~bi11~;ng the position during the stacking of several platforms. It is also not possible to nest as many hollow-section bars into one ~nother as desired, rather only t~o can be nested together at a time.
A further platform is known from the Patent Application FR 2 501 26? Al, in which the hollow-section bars can be connected with one another through grooves and fitting elastic tongues. The ledgelike elastic tongues have thereby a continuous head ledge, which must be moved into a groove Or the aqjacent hollow-section bar. The larg~ head ledge can have a round, triangular or recta~gular cross section complementary ~ith the groove.
The elastic tongues are thereby char~cterized in this design by a material accumulation, ~hich is detrimental for a tension-free ~anufacture of the hollow-section bars, which are moreover manufactured with overall approximately the same wall thic~ness. ~owever, it is particularly unfavorable that the asse~bly of the hollow-sectlon bars brings about significant problems because these ~ust be inserted against one another par~llel to their longitudinal axes in order to create the connection between a groove and an elastic tongue.
The piecing together of the hollow-section bars to form a flooring is therefore very time consuming. In addition, the individual hollow-seation bar~, just like the completed platforms, are not secured during stacking.
S Whereas $t is also already known from the Patent Application EP 0 300 399 A3 to e~uip the longitudinal supports, which lie on the outsids of a platform and are ~ n~d as hollow-seation bars, with longitudinal and stacking ribs. With the help of the ribs, several lo platforms can be stacked one on top of the other, and can thereby be locked transversely to their longitudinal axis. It i~ actually obvious to provide ~uch an ~ rt also in the case of hollow-section bars, from which a flooring for such a platform can be assembled.
1~ The large ~ LLu~Lion of the longitudinal and stacking ribs, however in turn, result~ in an undesired material ~n~ 1 ~tion in this area and increases the danger of the for~ation of cracks after manufacture.
~herefore the basic purpose of the invention is to design a platform of the type identified in detail above with simple means safely operated, whereby large material ~ccumulations are avoided, and to ~onaLLu~L said platform in such a manner that additional ~nnn~tl ng elements between the hollow-section bars are not needed, and the platforn can still be assembled to be inherently stable.
A staaking aid for the platform i8 also desired.
Furthermora, the number of the parallel hollow-section bars can be any number as is desired so that an ad~antageous width of the platform does not depend on the width of the hollow-section bars. ~he hollow-section bars, howe~er, are able to be quickly coupled to one another, whereby such a coupling gains stability for a load on the platform.
The purpose is attained according to the invention in such a manner that on the one hand a parallel, vertical ~eb i5 formed Ln one piece on the elastic tongue, which web can be introduced into a parallel secondary groove leceaaed into the lower ~idew~ll of the groove, whereas on the other hand both the elastic tongue and also the groOve end ln edge ledges, ~hich are parallel to one another and are approximately flat. The heights of the web or rather of the cPrnh~ry groove are adjusted to the heights of the elastia tongue or rather of the groove in such a manner th~t the elastic tongue can be swung into the groove when the web is introduced into the ~ y groove.
A platform of the invention can be A~ 'led out of individual hollow-section bars without any advanced tenhnjt~l knowledge and can be fiYedly connected through the groove and tongue cnnr~ ion in such a manner that a stable walkable surface can be a~embled of very light extruded parts. The parts Are neither screwed nor riveted together and can be joined together in any desired number. In the case o~ light construction ~ti~n~, a narrow separation thereb~L~en guarantees, through the large number of the vertical crosspieces of the individual hollow-section bars which crnccpl~n~c determine the woment of resistance, a high supporting capacity of the platform.
The rlooring can now be ~Cst~hl~ very quLckly out of the indlvidual hollow-section bars, because their elastic tongue can be lateraIly guided easily into the respective s~nn~ry groove and can be placed into same, whereafter the bollow-sectlon bars must only be s~ivelled with respect to one another about a swivel axis, which is ao~ r~ by the p~iring of elastia tongue / sec~n~ry groove. Such a swivelling asse~bly reguires very little ti~e. When the edge ledge~ of the elastic tongue and of the groove are placed one on top Or the other, then the position o~ use has been reached. It aan easily be understood that with a load on the platform through the ~5 continuously existing swivelllng car~hility of the hollow-section bars about the swivel axis, the locking Or said hollow-section bars with respect to one another is further reinforced and the applied loads are distributed through the edge ledges onto all adj~cent hollow-section bars. A further advant~ge of the arr~rJ ~t consists in both the bending resistance in the longitudinal direction and also the inherent stability in the transverse ~lirection of the platform being improved.
The hollo~-section bars can be constructed essentially ~ith an all around, approximately constant wall ~hlr~nr~e5 including the areas of groove and el~stic tongue. Such a design is technologically favorable becau~e thermal stress is avoided as much as possihle during their manufacture, which thermal stress can occur with variations in the wall thickness.
It is particularly useful when the outer edge hollow-section bars forming the longitudinal sides of the support frane are prouided on their top surface, which serves as the stepping surfacs, and the bottom surface, which lies opposite said top surface and has identical di~ensions, each with at least one bead, which is adjacent and parallel to the smooth side surface. In particular, when the bead is raised ln the top surface and the one in the bottom surface is reGessed - but for the imprGved inherent stability - the condition is created for the beads to be dimensioned such that, when the platforms are placed one on top of the other, they aat as a stacking aid by engaging one another and preventing reciprocal transverse shifting of the platforms.
~he platform is completed, in an advantageous manner, when the support section is dr~sir3nr~rl as a U or L-shaped ~ection and the hollow-section bars rest on the lo~er horizontal belt following the vertic~l crosspiece of the U or L-~haped section, whereby the hollow-section bars can be fastened with their end areas, at least partially, to the support section. It can already be sufficient to fasten the outer edge hollow-section bars to the support seG~iQnc and to merely place the others on 2 ~ 9 ~ 88 1 the support sections therebetween, in particular when using ~-shaped ~~t; n~.
The platfor~ Or the lnvention makes it possible to construct the hollow-section bars forming the longitudinal sides of the platform the s2me or mirror imaged with respect to the opposite side. It is advantageous in the latter casel when a hollow-section ~ar on both ~ide surfaces either iG provided on eaGh side with a groove or instead each side with ~n elastic tongue.
It i8 possible to Ztc~mhlP with ~he platfor~ o~ the invention platforms with very different widths out of the same basia structural element. The manufacture and the storage can, in this manner, be limited to few different structural Pl ts and can accordingly be simplified.
The invention will ~te dicCllcc~d in greater detail herelnafter in conn~rtion with one exemplary Pttt~o~;r -t and the &a~ings, in which:
Figure 1 illustrates a hOlloW-section bar for a platform of the inYentlon, ~ igure 2 illustrates a further hollow-section bar, Figure 3 illustrates two stacked hollow-section bars, ~ igure 4 illustrates ~ narrow platform Or the lnYention, and Figure 5 illustrates a similar, howeYer, wide platform, all il}ustrated in cross section and simplified.
A h~tll~t~: _cction bar 1, according to Figure l, is manufactured in an extrusion process and has an ~prvsl~t~-ly rectangular cross section. A groove ll is recessed in a fir~t side surface la so that a longittl~intlly continuously Pytpn~;ng ledge 12 or 1} is positioned at the top and at the bottom. The lower ledge 13 is thick, however, a secondary groove 13a is recessed therein so as to open into the grooYe la, and is separ~ted from the side surface la by a crrt~cr~p~p 13b.
~ 2 ~ 9 1 88 1 A second side surface lb is provided - complimentarily to the groove 11 - uith a raised elastic tongue 14 so that a longit~;n~lly continuously extending resldual space 15 or 16 remains at the top and at the bottom thereof. ~
web }4a projects into the lower residual space 16, which web has a crcss section shaped complementary to the secondary groove 13a. A top sur~aoe lc and a bottom surface ld extend between the side surfaces to complete the cross section of the hollow-section bar 1. The top sur~ace lc is ~a~u ed such that it is safe for a person to step on it.
Figure 5 shows that as many hollow-section bars 1 as desired can be provided side-by-side with the groove 11 raceiving the elastic tongue 14. The secondary groove 13a receives the web 14a, and the upper residual spaces 15 are each filled in with an upper ledge 12. The hollow-~ection bars 1 are in this ~anner securely connected with one another. ~he ledges 12 rsst after the assembly and the swinging in of the hollow-section bars 1 with their (lower~ horizontal edge ledges on the ~upper) edge ledges of the elastic tongue 14 Another hollow-section bar 1' only slightly different from the one of Figure 1 is illustrated in cross section in Figure 2. It is used for receiving an elastic tongue 14 on both sides ahd is thus e~uipped with a groove 11' on both side surfaces la', whereby the grooves 11' are designed symmetrical about a central vertioal axis, houever, otherwise, they do not differ ~rom the groove 11 of Figure 1. A ledge 13' is ~ ~Lical about the central vertical axis and is below the top surface lc~- ~he residual spaces 15, 16 do not exist here on the hollow-section bar 1~. Figures 4 and 5 clearly show that the platform of the invention requires at ~ost one hollow-section bar 1', either (~igure 4) between two outer edge hollow-section bars 1" or ~Figure S~ between an "inner" hollou-section bar 1 and cne o~ the outer sdge hollow-secticn bars ln.
The outer edge hollow-section bars 1" at the outer longitudinal edge of the plat~orm of the invention are illustrated - placed one above the other - in Figure 3 They differ ~rom the hollow-section bars 1 and 1' only by not having an elastic tongue 14 on the associated side surface lb", instead it is ~o~eq as a smooth wall ~urface. Both side D~rf~c~s lb" are thus parts o~ the platfor~, which are formed as ~-s~aped or L-shaped support se~t1~nC on the sides facing the transverse lo direction of the platform, on which support sections other hollow-section bars are ~ VL L~d. In the simplest design, they rest on the tlouer) belt of the respective support section, and are connected - at le~st the outer edge hollow-section bars 1" - positlvaly or with self locking to the respective support section. ~o~ever, the details can be designed relatively as desired, are not directly connected with the invention and are not shown in the drawingS.
~he top sur~ace lc" and the bottom surface ld"
2G adjacent the vertical smooth side surfaces Lo~ includes beaas }7 or 18 The beads 1~ of the top surface lc" are raised and the ~eads 18 in the bottom surfaces ld" are recassed. They are equally spaced ~rom the next side surface lb" and are shaped such that they, when the Z5 hollow-section bars l~ are stacked and, accordingly, the platforms are also stacked, engage one anothOE in such a manner that the top and ~ottom surfaces 1cr lc', lc" and ld, ld~, ld" rest on one another in a rlat c~ ing arrangement. It is thereby at the sama time assured that transversely directed mo~ements of the stacked hollow-section bars or platforms are prevented

Claims (10)
1. A platform for scaffoldings, in particular scaffoldings for the construction industry or the like, whereby the platform is assembled out of one support frame forming its longitudinal sides and its transverse sides perpendicular thereto, and defining and locking a floor serving as a treading surface thereon, and at least two one-piece hollow-section bars (1), which are releasably connected with one another at their longitudinal sides to form the flooring, whereby the hollow-section bars (1) are constructed as closed extrusions, the side surface (1a, 1b) of which abut one another and are parallel with the longitudinal sides of the support frame, have on the one side of the respective hollow-section bar (1) a continuous groove (11) parallel with the side surface (1a), and on the other side an elastic tongue (14) complementarily formed with the groove (11), whereby two adjacent hollow-section bars (1) can be connected with one another with the groove (11) of the one hollow-section bar (1) receiving the elastic tongue (14) of the other hollow-section bar (1) therein, whereby the longitudinal sides of the support frame are also formed by a similarly connectable hollow-section bar (1"), which on its side - forming the outer boundary of the support frame - has a side surface (1b") of any desired design, preferably of a smooth design, however, the side surface is equipped on the respective other side surface (1a") facing an adjacent hollow-section bar (1, 1') with a groove (11) or an elastic tongue (14), and whereby the transverse sides of the platform are each provided with a support section, on which the flooring rests and which is used to fasten the platform to the remaining scaffolding, characterized in that on the one hand, a parallel, vertical web (14a) is formed in one piece to the elastic tongue (14), which web can be introduced into a parallel secondary groove (13a) recessed into the lower sidewall of the groove (11, 11'), on the other hand, both the elastic tongue (14) and also the groove (11) end in edge ledges which are parallel to one another and are approximately flat, whereby the heights of the webs (14a) or, rather, of the secondary groove (13a) are adjusted with the heights or the elastic tongue (14) or, rather, or the groove (11) in such a manner that the elastic tongue can be swung into the groove (11) when the web (14a) is introduced into the secondary groove (13a).
2. The platform according to Claim 1, characterized in that the outer edge hollow-section bars (1") forming the longitudinal sides of the support frame are each provided with at least one bead (17, 18) on their top surface (1c") serving as the stepping surface and on the bottom surface (1d"), which has the same dimensions and is opposite said top surface, which beads are adjacent and parallel to the smooth side surface (1b").
3. The platform according to Claim 2, characterized in that the bead (17) in the top surface (1c") is raised and the bead (18) in the bottom surface (1d") is recessed.
4. The platform according to Claim 2 or 3, characterized in that the beads (17, 18) are dimensioned such that they, when the platforms are placed one onto the other, engage one another and act as a stacking aid to prevent a transverse shifting of the platforms.
5. The platform according to one of the Claims 1 to 4, characterized in that the support section is designed as a U-shaped or L-shaped section, and the hollow-section bars (1, 1', 1") rest on the lower horizontal belt following the vertical crosspiece of the U-shaped or the L-shaped section.
6. The platform according to Claim 5, characterized in that the hollow-section bars (1, 1', 1") are fastened with their end areas at least partially to the support section.
7. The platform according to Claims 1 to 6, characterized in that the hollow-section bars (1") forming the longitudinal sides of the platform are constructed identically.
8. The platform according to Claims 1 to 6, characterized in that the hollow-section bars (1") forming the longitudinal sides of the platform are constructed as mirror images of each other.
9. The platform according to Claim 8, characterized in that a hollow-section bar (1') is provided on both side surfaces (1a') each with either a groove (11'), or with each an elastic tongue (14').
10. The platform according to one of the Claims 1 to 9, characterized in that the hollow-section bars (1, 1', 1") are constructed with a wall thickness, which is approximately constant on all sides.
