Abstract

Load bearing profile beam, which in the first instance is intended for use on building sites. It involves an extended load surface (10) which is equipped with sidelong cavity profiles (11, 12). These cavity profiles have a flat topside which makes up part of the load-bearing surface. The cavity profile's arrangement gives the profile beam an improved movement rigidity and ease of conveyance.The cavity profiles are preferably made of two joined components (11a-11b, 12-12b) which are joined in the cavity profile's neutral plane. This facilitates the modification of the profile beam and makes possible hole-punching or cross-grooving of the whole load-bearing surface (10) for effecting a slip guard. The components (10a) of the profile beam situated between the cavity profiles (11, 12) are furnished with one or more reinforcing flanges (21) on their undersides.<IMAGE>

Description

8103042-1 2 Än utföringsform av profilbalken enligt uppfinningen skall' nu närmare beskrivas nedan med hänvisning till den bifogade rit- ningsfiguren, vilken visar en tvärsektion genom profilbalken. 8103042-1 2 As an embodiment of the profile beam according to the invention, will now be described in more detail below with reference to the accompanying figure, which shows a cross section through the profile beam.

Den i ritningsfiguren visade profilbalken har en plan övre yta 10, vilken utgör balkens belastningsyta. Profilbalken är ut- med sina längsgående sidokanter utformad med hålprofiler 11 och 12, vilka sträcker sig kontinuerligt utmed balkens hela längd.The profile beam shown in the drawing figure has a flat top surface 10, which constitutes the load surface of the beam. The profile bar is with its longitudinal side edges formed with hollow profiles 11 and 12, which extend continuously along the entire length of the beam.

Var och en av dessa hålprofiler 11 och 12 är uppbyggd av två de- lar 11a,11b resp 12a,12b. Dessa delar har väsentligen Ü-formad tvärsektion och är vända mot varandra, så att de tillsammans bil- dar ett rör med rektangulär tvärsektion, vilket utgör hàlprofilen.Each of these hole profiles 11 and 12 is made up of two parts. lar 11a, 11b resp 12a, 12b. These parts are substantially Ü-shaped cross-section and face each other, so that together they there is a tube with a rectangular cross-section, which forms the hollow profile.

Hålprofilernas övre delar 11a,12a utgör en del av belastningsytan 10 och ligger i samma plan som den övriga delen 10a av belast- ningsytan 10. I Varje hålprofil är såsom ovan nämnts uppbyggd av två U-formade delar 11a,11b resp 12a,12b. Den övre delen 11a,12a i varje par är försedd med nedåtriktade skänklar 13,1H resp 15,16. Den undre de- len 11b,l2b i varje par är försedd med uppätriktade skänklar 17,18 resp 19l20. Dessa uppåtriktade skänklar är vid sina övre fria än- dar inåtböjda, så att skänklarnas ändar kan skjuta in i den till- hörande övre profildelen. Inåtböjningen är så avpassad, att skänk- larnas fria ändar med snäv passning kan skjuta in i mellanrummet mellan skänklarna på de övre delarna. Delarna i varje par samman- hålles medelst icke visade punktsvetsar. Sammanfogningspunkterna mellan profildelarna i varje par och sålunda delningsplanet för hålprofilerna ligger väsentligen i profilbalkens neutralplan.The upper parts 11a, 12a of the hole profiles form part of the load surface 10 and is in the same plane as the other part 10a of the load ningsytan 10. I Each hole profile is, as mentioned above, made up of two U-shaped parts 11a, 11b and 12a, 12b respectively. The upper part 11a, 12a in each pair is equipped with downward legs 13.1H and 15.16 respectively. The lower de- len 11b, l2b in each pair are provided with upright legs 17,18 resp 19l20. These upward-pointing legs are at their upper free ends. bent inwards, so that the ends of the legs can slide into the belonging to the upper profile part. The inward bend is so adapted that the donor the free ends of the lugs with a tight fit can slide into the gap between the legs of the upper parts. The parts of each pair are held by spot welds (not shown). The joining points between the profile parts of each pair and thus the division plane of the hole profiles are essentially in the neutral plane of the profile beam.

Den i ritningsfiguren visade profilbalken består sålunda av tre delar, nämligen överdelen med bekßtningsytan 10 och de två i denna ingående överdelarna 11a och 12a i hålprofilerna 11 och 12 och de två separata underdelarna 11b och 12b för hålprofiler- na. Dessa underdelar 11b och 12b är sinsemellan exakt lika. Ge- nom denna uppdelning av profilbalken i tre delar, av vilka två är lika, blir profilbalken mycket lätt att tillverka.The profile beam shown in the drawing figure thus consists of three parts, namely the upper part with the covering surface 10 and the two in this included the upper parts 11a and 12a in the hole profiles 11 and 12 and the two separate lower parts 11b and 12b for the hole profiles na. These lower parts 11b and 12b are exactly the same. Give- by dividing the profile beam into three parts, two of which is equal, the profile beam becomes very easy to manufacture.

Den övre profilbalksdelen 10,11a,12a är på undersidan mellan hålprofildelarna 11a,12a försedd med en nedåtriktad fläns 21, vilken tjänar till att ytterligare förstyva profilbalken. För- styvningsflänsen 21 är anordnad i balkens längsgående vertikala _mittplan. 3 8103042-1 Om profilbalken skall användas i byggnadsställningar, förses 'den vid sina ändar med kloliknande hakar eller krokar, så att profilbalken kan anbringas mellan eller på tvärgående balkar el- ler rör i byggnadsställningarna. Dessa hakar eller krokar kan vara av tidigare känd typ och har därför icke visats i ritninga- figuren. Hakarna eller krokarna anbringas i profilbalkens hål- profiler och fästes i dessa genom fastskruvning eller svetsning. Även om endast en utföringsform av profilbalken enligt upp- finningen visats och beskrivits ovan är det uppenbart, att många modifikationer och variationer är möjliga inom ramen för uppfin- ningstanken. Hålprofilerna behöver t ex icke bestå av flera de- lar utan hela profilbalken kan strängsprutas såsom en enhet. Om hålprofilerna är upndelade i två delar med U-formade tvärsektio- ner, kan de fria skänklarnas kanter på den ena eller den andra delen utformas pä många olika sätt för att säkerställa en till- fredsställande sammanfogning av delarna. Vidare kan flera för- styvningsflänsar anordnas på den övre profilbalkdelens undersida.The upper profile beam part 10, 11a, 12a is on the underside between the hollow profile parts 11a, 12a provided with a downwardly directed flange 21, which serves to further stiffen the profile beam. For- the stiffening flange 21 is arranged in the longitudinal vertical of the beam _mittplan. 3 8103042-1 If the profile beam is to be used in scaffolding, it is provided 'it at its ends with claw-like hooks or hooks, so that the profile beam can be mounted between or on transverse beams or pipes in the scaffolding. These hooks or hooks can be of a previously known type and have therefore not been shown in the drawing. the figure. The hooks or hooks are placed in the profile beam holes. profiles and fastened to them by screwing or welding. Although only one embodiment of the profile beam according to The finding shown and described above is obvious to many modifications and variations are possible within the scope of the invention. ningstanken. The hole profiles, for example, do not have to consist of several without the entire profile beam can be extruded as a unit. If the hole profiles are divided into two parts with U-shaped cross-sections. down, the edges of the free legs can be on one or the other the part is designed in many different ways to ensure a satisfactory joining of the parts. Furthermore, several stiffening flanges are arranged on the underside of the upper profile beam part.

Dessa förstyvningsflänsar bör då placeras så, att de ligger sym- metrískt i förhållande till profilbalkens längsgående vertikala mittplan. Balkens belastningsyta kan förses med utstansade hål, såsom ovan nämnts, eller med längsgående räfflor, såsom visas på ritningsfiguren, för åstadkommande av ett gott halkskydd eller alternativt med ett:halkningsförhindrande beläggningsskikt.These stiffening flanges should then be positioned so that they are sym- metric in relation to the longitudinal vertical of the profile beam midplane. The load surface of the beam can be provided with punched holes, as mentioned above, or with longitudinal grooves, as shown on the drawing figure, to provide a good anti-slip protection or alternatively with a: anti-slip coating layer.
