Description
10 40 469 968 2 fig. 4 visar en ändvy av en del av den färdiga profilerade plåtprofilen enligt uppfinningen, här även försedd med en förstyvande extra plåtprofil. 10 40 469 968 2 Fig. 4 shows an end view of a part of the finished profiled the sheet metal profile according to the invention, here also provided with a stiffening extra sheet metal profile.
Uppfinningen avser således till en del en plåtprofil, speciellt en s.k. högprofil, med en utformnig såsom speciellt framgår av fig. 4. Plåtprofilen innefattar ett övre flänsparti 1, och två från detta övre flänsparti sig nedåt sträckande, huvudsakligen vertikalt sig sträckande, liv 2 och 3. Dessa båda liv övergår vid sina nedre ändar i ett resp. undre flänsparti 4 som förbinder dessa båda liv 2 och 3 med resp. liv 3 och 2 på nästa profilupphöjning.The invention thus relates in part to a sheet metal profile, especially a so-called high profile, with a design such as special is shown in Fig. 4. The sheet metal profile comprises an upper flange portion 1, and two downwardly extending from this upper flange portion, mainly vertically extending, life 2 and 3. These two life merges at its lower ends into a resp. lower flange portion 4 which connects these two lives 2 and 3 with resp. lives 3 and 2 on next profile increase.
För att förstyva plåtprofilen och ge den högre bärighet är i liven 2 och 3 utformat lokala inpressningar 5, vilka lämpligtvis är omväxlande pressade åt olika håll i plåten, eller utåt och inåt såsom sett i fig. 1 eller fig. 4. Detta framgår speciellt av fig. lb och lc. Inpressningarna 5 har huvudsakligen parallellogramform, eventuellt rektangulära, med större utsträckning i livens 2, 3 höjdriktning än i plåtpro- filens längdriktning. Såsom framgår av fig. la och fig. 4 sträcker sig inpressningarna 5 över större delen av livens 2, 3 höjd. Inpressningarna 5 är, när de icke har rektangulär form, utformade så att de omväxlande lutar mot varandra såsom framgår av fig. la.To stiffen the sheet metal profile and give it higher bearing capacity are formed in the webs 2 and 3 local indentations 5, which suitably are alternately pressed in different directions in the plate, or outwards and inwards as seen in Fig. 1 or Fig. 4. This is particularly apparent from Figs. 1b and 1c. The indentations 5 have mainly parallelogram shape, possibly rectangular, with to a greater extent in the height 2, 3 direction of life than in sheet metal the longitudinal direction of the file. As shown in Fig. 1a and 4 the indentations 5 extend over most of the life 2, 3 height. The indentations 5, when they are not rectangular in shape, are designed so that they alternately lean towards each other as shown of Fig. 1a.
De ovannämnda inpressningarna 5 har lämpligtvis åstad- kommits i den plana plåten innan denna profilerats till'den veckade plåtprofilen. Vid profilíeringen av den plana plåten till den veckade plåtprofilen kan plåtprofilen även förses med ytterligare förstyvningsveck 6 sträckande sig i plåtprofilens längdriktning och belägna i lämpligtvis både det övre fläns- partiet 1 och det undre flänspartiet 4. Dessa förstyvningsveck 6 framgår av fig. 4.The above-mentioned indentations 5 have suitably provided placed in the flat plate before it has been profiled to it pleated sheet metal profile. When profiling the flat plate to the pleated sheet metal profile, the sheet metal profile can also be provided additional stiffening fold 6 extending in the sheet metal profile longitudinally and conveniently located in both the upper flange the portion 1 and the lower flange portion 4. These stiffening folds 6 is shown in FIG.
För en ytterligare förstyvning av plåtprofilen kan vid användning av densamma i plåtprofilens veck vara insatt en förstyvande huvudsakligen U-formad förstärkningsprofil 7, som är insatt under de övre flänspartierna 1 och mellan liven 2 och 3, såsom framgår av fig. 4. Den U-formade förstärkningsprofilen 7 är med de fria ändarna av sina skänklar 8 och 9 stödande mot undersidan av det övre flänspartiet och den U-formade för- stärkníngsprofilens horisontella del 10 är anordnad liggande huvudsakligen i plan med plåtprofilens undre flänsparti 4 för 40 3' 469 968 att liksom plåtprofilens undre flänsparti kunna vila på en tvärbalk. Förstärkningsprofilens U-formade skänklar 8 och 9 är lämpligtvis även de försedda med inpressningar 11 motsvarande inpressningarna 5 i plåtprofilens liv 2 och 3. På detta sätt erhålles en mycket styv förstärkningsprofil 7 för att ytterli- gare öka bärigheten hos plåtprofilen enligt uppfinningen.For a further stiffening of the sheet metal profile can at use of the same in the folds of the sheet metal profile be inserted one stiffening mainly U-shaped reinforcement profile 7, which is inserted below the upper flange portions 1 and between the webs 2 and 3, as shown in Fig. 4. The U-shaped reinforcement profile 7 is with the free ends of its legs 8 and 9 supporting against the underside of the upper flange portion and the U-shaped the horizontal part 10 of the reinforcing profile is arranged horizontally substantially flush with the lower flange portion 4 of the sheet metal profile for 40 3 '469 968 as well as the lower flange portion of the sheet metal profile to be able to rest on one crossbeam. The U-shaped legs 8 and 9 of the reinforcement profile are suitably also those provided with indentations 11 correspondingly the indentations 5 in the plates 2 and 3 of the sheet metal profile. In this way a very rigid reinforcement profile 7 is obtained to further further increase the bearing capacity of the sheet metal profile according to the invention.
Uppfinningen innefattar även, såsom nämnts ovan, ett förfarande för framställning av plåtprofilen enligt uppfin- ningen. Detta förfarande åskådliggöres främst med hjälp av fig. 2 och 3, av fig. 2 framgår att en tunnplåt 12 matas in mellan ett första samverkande valspar 13a, 13b och sedan genom ett andra samverkande valspar 14a, 14b. Båda valsparen 13 och 14 är försedda med samverkande upphöjningar 15 och urtagningar 16, där dock upphöjningarna och urtagningarna på det första valspa- ret 13 har ett större djup inpressande en djupare inpressning i plåten medan upphöjningen och urtagningen på det andra valspa- ret 14 har ett mindre djup än det första valsparet och där- igenom tíllbakapressande en del av inpressningen 5 i plåten, såsom framgår vid en jämförelse mellan fig. lb och fig. lc och såsom speciellt även framgår av den större vyn visad i fig. 3a, fig. 3b. Inpressningsdjupet i det första valsparet 13 kan t.ex. vara 2,5 mm, och det andra valsparet 14 har ett inpressnings- djup på enbart 1,5 mm, således tillbakapressande plåten 1 mm.The invention also comprises, as mentioned above, a process for producing the sheet metal profile according to the invention ningen. This method is mainly illustrated by means of fig. 2 and 3, Fig. 2 shows that a sheet 12 is fed in between a first cooperating pair of rollers 13a, 13b and then through one other cooperating roller pairs 14a, 14b. Both roller pairs 13 and 14 are provided with cooperating elevations 15 and recesses 16, where, however, the elevations and recesses on the first roll ret 13 has a greater deep indentation a deeper indentation in plate while the elevation and recess on the second roller the 14 has a smaller depth than the first pair of rollers and through back-pressing a part of the indentation 5 in the plate, as can be seen from a comparison between Fig. 1b and Fig. 1c and as is also particularly apparent from the larger view shown in Fig. 3a, Fig. 3b. The indentation depth in the first pair of rollers 13 can e.g. be 2.5 mm, and the second pair of rollers 14 has a depth of only 1.5 mm, thus compressing the plate 1 mm.
På detta sätt erhålles en styvare inpressning än vad som skulle vara fallet om pressningen skedde enbart i ett steg till ett bestämt djup. Denna typ av inpressning genomföres både på den plåt som ska bilda plåtprofilen liksom även på den plåt som användes till den eventuellt förekommande förstärkningsprofilen 7.In this way a stiffer impression is obtained than would be the case be the case if the pressing took place only in one step to one certain depth. This type of pressing is performed both on it sheet metal that will form the sheet metal profile as well as on the sheet metal that was used for the possible reinforcement profile 7.
Efter det att en tunnplåt försetts med inpressningarna 5 i valsparen 13 och 14 förs tunnplåten vidare till ett pro- fileringsverk av vanligt slag för att bilda en profilplåt, exempelvis av det utseende som visas i fig. 4. På motsvarande sätt förfares även med den eventuella förstärkningsprofilen 7.After a sheet is provided with the indentations 5 in roller pairs 13 and 14, the sheet is passed on to a filing plant of ordinary type to form a profile plate, for example, of the appearance shown in Fig. 4. On the corresponding procedure is also carried out with the possible reinforcement profile 7.
Det är självklart att plåtprofilen enligt uppfinningen ej behöver ha den profilform som visas i fig. 4, utan den kan ha vilken som helst för ändamålet lämplig profilform, då det viktiga med uppfinningen är just att åstadkomma förstyvningen genom inpressningar i plåtprofilens liv.It is obvious that the sheet metal profile according to the invention does not need to have the profile shape shown in Fig. 4, but it may have any profile shape suitable for the purpose, then important with the invention is precisely to achieve the stiffening by indentations in the life of the sheet metal profile.
