Description
Oppfinnelsen angår en stålbjelke som sammen med betong er innrettet til å utgjøre en bærende, sammensatt struktur for forskjellige betongdekkesystemer, idet den sammensatte struktur omfatter en basisplate og to stegdeler anordnet side ved side i avstand fra hverandre og sammenføyd ved første ender av stegdelene ved hjelp av en horisontal toppdel, slik at basisplaten, stegdelene og den horisontale toppdel er anordnet slik at de danner et rom som kan fylles med betong. The invention relates to a steel beam which, together with concrete, is arranged to form a load-bearing, composite structure for various concrete covering systems, the composite structure comprising a base plate and two step parts arranged side by side at a distance from each other and joined at the first ends of the step parts by means of a horizontal top part, so that the base plate, the step parts and the horizontal top part are arranged so that they form a space that can be filled with concrete.
Oppfinnelsen angår en bjelke som de bærende strukturer i en bygning, slik som dekker med hul kjerne, kompositt-dekker, skalldekker og slike som kan støpes på stedet (cast-in-situ), kan understøttes på. Under fylling av fuger eller annen bruk av betong fylles bjelken med betong, og etter at betongen har herdet utgjør bjelken en sammensatt struktur. Bjelker av denne type er i dag velkjent på området elementstrukturer. Eksempler på løsninger som er kjent på området er slike som beskrevet i publikasjonene Fl 85745 og Fl 92089. Bruken av en sammensatt struktur frembringer en stålbjelke som er lettere enn de tidligere, og bjelken kan benyttes som lengre bære-elementer enn de tidligere bjelker. The invention relates to a beam on which the load-bearing structures in a building, such as hollow-core decks, composite decks, shell decks and the like that can be cast-in-situ, can be supported. During filling of joints or other use of concrete, the beam is filled with concrete, and after the concrete has hardened, the beam forms a composite structure. Beams of this type are today well known in the field of element structures. Examples of solutions that are known in the area are those described in publications Fl 85745 and Fl 92089. The use of a composite structure produces a steel beam that is lighter than the previous ones, and the beam can be used as longer supporting elements than the previous beams.
Løsningene i henhold til kjent teknikk, slik som løsningene beskrevet i de ovenfor nevnte publikasjoner, utgjør strukturer uten problemer. Det har imidlertid under bygging oppstått behov for bjelker med bedre skjærkapasitet enn de kjente løsninger. The solutions according to the prior art, such as the solutions described in the above-mentioned publications, constitute structures without problems. However, during construction there has been a need for beams with better shear capacity than the known solutions.
Et formål med oppfinnelsen er således å komme frem til en stålbjelke som innlednings-vis beskrevet, med hvilken ulempene ved den kjente teknikk kan elimineres. One purpose of the invention is thus to arrive at a steel beam as described in the introduction, with which the disadvantages of the known technique can be eliminated.
Dette er oppnådd med den foreliggende oppfinnelse, idet stålbjelken i henhold til oppfinnelsen kjennetegnes ved at i det minste én stegdel er fremstilt av en platedel dannet av to langsgående partier av bjelken som er i en vinkel med hverandre, og at platedelen er festet til basisplaten og toppdelen på en slik måte at det nedre parti av stegdelen er i en vinkel med basisplaten og det øvre parti er hovedsakelig vinkelrett på basisplaten. This has been achieved with the present invention, as the steel beam according to the invention is characterized by the fact that at least one step part is made of a plate part formed by two longitudinal parts of the beam which are at an angle to each other, and that the plate part is attached to the base plate and the top part in such a way that the lower part of the step part is at an angle with the base plate and the upper part is substantially perpendicular to the base plate.
Fordelen med oppfinnelsen i forhold til den kjente teknikk er fremfor alt at skjærkapa-sitéten til bjelken i henhold til oppfinnelsen er vesentlig bedre enn skjærkapasiteten til en bjelke i henhold til kjent teknikk. Stålbjelken i henhold til oppfinnelsen er også enkel, slik at implementering og bruk av oppfinnelsen er fordelaktig. En annen fordel med oppfinnelsen er at den kan modifiseres etter behov, slik at å bruke den blir fordelaktig. Enda en fordel er at bjelken i henhold til oppfinnelsen kan fremstilles i de samme produksjonslinjer som de tidligere kjente bjelker. The advantage of the invention in relation to the known technique is above all that the shear capacity of the beam according to the invention is significantly better than the shear capacity of a beam according to the known technique. The steel beam according to the invention is also simple, so that implementation and use of the invention is advantageous. Another advantage of the invention is that it can be modified as needed, so that using it becomes advantageous. Another advantage is that the beam according to the invention can be produced in the same production lines as the previously known beams.
I det følgende skal oppfinnelsen beskrives nærmere ved hjelp av foretrukne utførelser vist på de vedføyde tegninger, på hvilke: In the following, the invention will be described in more detail using preferred embodiments shown in the attached drawings, on which:

Fig. 1 og 2 er generelle avbildninger av stålbjelken i henhold til oppfinnelsen, som sammen med betong er beregnet til å utgjøre en bærende, sammensatt struktur for forskjellige betongdekkesystemer. Bjelken omfatter en basisplate 1 og to stegdeler 2, 3. Stegdelene 2, 3 er anordnet side ved side i avstand fra hverandre og sammenføyd ved de første kanter av stegdelene 2, 3 ved hjelp av en horisontal toppdel 4. Stegdelene 2, 3 og den horisontale toppdel 4 er innrettet til å danne et rom som kan fylles med betong. Stegdelene 2, 3 har åpninger 6, gjennom hvilke betong kan tilføres til rommet dannet av basisplaten 1, stegdelene 2, 3 og toppdelen 4. Bjelken har også flenskraver 5, som f.eks. et dekke med hul kjerne er anordnet på. Alle de ovenfor nevnte bjelkedeler kan tilskjæres av en stålplate. Fig. 1 and 2 are general views of the steel beam according to the invention, which, together with concrete, is intended to form a load-bearing, composite structure for various concrete covering systems. The beam comprises a base plate 1 and two step parts 2, 3. The step parts 2, 3 are arranged side by side at a distance from each other and joined at the first edges of the step parts 2, 3 by means of a horizontal top part 4. The step parts 2, 3 and the horizontal top part 4 is arranged to form a space which can be filled with concrete. The step parts 2, 3 have openings 6, through which concrete can be supplied to the space formed by the base plate 1, the step parts 2, 3 and the top part 4. The beam also has flange collars 5, which e.g. a hollow core cover is arranged on. All of the above-mentioned beam parts can be cut from a steel plate.
Stålbjelkens virkemåte som sammensatt struktur er kjent for fagfolk på området, og trenger derfor ikke beskrives nærmere her. I denne sammenheng henvises det til f.eks. publikasjonene Fl 85745 og Fl 92089 nevnt ovenfor. The operation of the steel beam as a composite structure is known to professionals in the field, and therefore does not need to be described in more detail here. In this context, reference is made to e.g. the publications Fl 85745 and Fl 92089 mentioned above.
I henhold til den essensielle idé ved oppfinnelsen er i det minste én stegdel 2, 3 laget av en platedel som er dannet av to langsgående partier, henholdsvis 2a, 2b og 3a, 3b, av bjelken. Partiene 2a, 2b og 3a, 3b befinner seg i en vinkel med hverandre. Den platedel som danner stegdelene 2, 3 er festet til basisplaten 1<p>g toppdelen 4 på en slik måte at det nedre parti 2a og 3a av stegdelene 2, 3 er i en vinkel med basisplaten 1, mens det øvre parti 2b, 3b er hovedsakelig vinkelrett på basisplaten 1. De ovenfor nevnte trekk er særlig klart vist i fig. 1. Åpningene 6 som betong kan tilføres gjennom til rommet dannet av basisplaten 1, stegdelene 2, 3 og den horisontale toppdel 4 er i denne utførelse dannet i de øvre partier 2b, 3b av stegdelene 2, 3. According to the essential idea of the invention, at least one step part 2, 3 is made of a plate part which is formed by two longitudinal parts, respectively 2a, 2b and 3a, 3b, of the beam. The parts 2a, 2b and 3a, 3b are located at an angle to each other. The plate part that forms the step parts 2, 3 is attached to the base plate 1<p>g top part 4 in such a way that the lower parts 2a and 3a of the step parts 2, 3 are at an angle with the base plate 1, while the upper parts 2b, 3b is mainly perpendicular to the base plate 1. The above-mentioned features are particularly clearly shown in fig. 1. The openings 6 through which concrete can be supplied to the space formed by the base plate 1, the step parts 2, 3 and the horizontal top part 4 are in this embodiment formed in the upper parts 2b, 3b of the step parts 2, 3.
I utførelsen vist i fig. 1 og 2 er begge stegdelene 2, 3 laget av en platedel, og henholdsvis partiene 2a, 2b og 3a, 3b av denne er i en vinkel med hverandre. Denne type løsning er imidlertid ikke den eneste mulige, og oppfinnelsen kan utføres på en noe annerledes måte. In the embodiment shown in fig. 1 and 2, both step parts 2, 3 are made of a plate part, and respectively the parts 2a, 2b and 3a, 3b of this are at an angle with each other. However, this type of solution is not the only possible one, and the invention can be carried out in a somewhat different way.
Således viser fig. 3 og 4 en andre utførelse av oppfinnelsen. De samme henvisningstall som i fig. 1 og 2 er benyttet i fig. 3 og 4 for tilsvarende elementer. Thus, fig. 3 and 4 a second embodiment of the invention. The same reference numbers as in fig. 1 and 2 are used in fig. 3 and 4 for corresponding elements.
Utførelsen i fig. 3 og 4 skiller seg fra utførelsen vist i fig. 1 og 2 ved at i utførelsen i fig. 3 og 4 er bare én stegdel 2 laget av en platedel, og partiene 2a og 2b av denne er i en vinkel med hverandre. I denne utførelse er den andre stegdel 3 laget av en rett platedel uten åpninger. The embodiment in fig. 3 and 4 differ from the embodiment shown in fig. 1 and 2 in that in the embodiment in fig. 3 and 4 is only one step part 2 made of a plate part, and the parts 2a and 2b of this are at an angle with each other. In this embodiment, the second step part 3 is made of a straight plate part without openings.
Utførelsen i fig. 3 og 4 er en usymmetrisk bjelke som er særlig egnet for kantstrukturer. En bjelke egnet for kantstrukturer betyr her den bjelke som danner kanten av en struktur, slik som et plan i en bygning, på en slik måte at stegplaten 3 uten åpninger danner planets kantflate. The embodiment in fig. 3 and 4 is an asymmetrical beam which is particularly suitable for edge structures. A beam suitable for edge structures here means the beam which forms the edge of a structure, such as a plane in a building, in such a way that the stepped plate 3 without openings forms the edge surface of the plane.
Ved fremstilling av bjelken i henhold til oppfinnelsen er det funnet særlig fordelaktig å benytte sidestøtter 7 og midtre støtter 8, vist med stiplede linjer i fig. 3. Sidestøttene 7 og de midtre støtter 8 kan være anordnet på basisplaten 1 med jevne mellomrom i lengderetningen av bjelken. De kan f. eks. være fastgjort ved sveising. Sidestøttene 7 er innrettet til å bestemme stillingen til stegplaten 2 som er utformet med åpninger 6 i forhold til basisplaten 1, og de midtre deler 8 er innrettet til å bestemme beliggenheten av stegdelene som er utformet med åpninger 6 i forhold til basisplaten 1, mens de midtre deler 8 er innrettet til å bestemme stillingen til platen som danner toppdelen 4. Sidestøttene 7 kan f. eks. være L-formet, slik som i fig. 3. Sidestøttene 7 og de midtre støtter 8 kan f. eks. være tilskåret av platemateriale. When manufacturing the beam according to the invention, it has been found particularly advantageous to use side supports 7 and middle supports 8, shown with dashed lines in fig. 3. The side supports 7 and the middle supports 8 can be arranged on the base plate 1 at regular intervals in the longitudinal direction of the beam. They can e.g. be fixed by welding. The side supports 7 are arranged to determine the position of the step plate 2 which is designed with openings 6 in relation to the base plate 1, and the middle parts 8 are arranged to determine the location of the step parts which are designed with openings 6 in relation to the base plate 1, while the middle parts 8 are arranged to determine the position of the plate which forms the top part 4. The side supports 7 can, e.g. be L-shaped, as in fig. 3. The side supports 7 and the middle supports 8 can e.g. be cut to size from sheet material.
Oppfinnelsen kan også utføres på en slik måte at stegdelene 2, 3 tilskjæres til buet form i henhold til hvelvingen av bjelken. Ved denne typen løsning er bruken av side-støtter og midtre støtter særlig fordelaktig, ettersom sidestøttene og de midtre støtter understøtter og styrer stegdelene og den horisontale toppdel meget effektivt under fremstillingstrinnet hvor basisplaten bøyes til en krumning som tilsvarer stegplatene. Når basisplaten bøyes på den måte som er beskrevet ovenfor, formes også platen som danner toppdelen 4 ved hjelp av de midtre støtter, til korrekt krumning. The invention can also be carried out in such a way that the step parts 2, 3 are cut to a curved shape according to the vaulting of the beam. In this type of solution, the use of side supports and middle supports is particularly advantageous, as the side supports and the middle supports support and guide the riser parts and the horizontal top part very effectively during the manufacturing step where the base plate is bent to a curvature that corresponds to the riser plates. When the base plate is bent in the manner described above, the plate which forms the top part 4 is also shaped with the help of the middle supports to the correct curvature.
Basisplaten 1, stegdelene 2, 3 og toppdelen 4 kan fortrinnsvis fastgjøres til hverandre ved sveising. Om nødvendig kan bjelken også utstyres med endeflenser som lukker endepartiene. Endeflensene fastgjøres ved sveising til endene av bjelken. The base plate 1, the step parts 2, 3 and the top part 4 can preferably be attached to each other by welding. If necessary, the beam can also be equipped with end flanges that close the end sections. The end flanges are attached by welding to the ends of the beam.
Den ovenfor angitteUtførelsen av oppfinnelsen er ikke ment å begrense oppfinnelsen på noen måte, idet oppfinnelsen kan modifiseres fritt innen omfanget av patentkrav-ene. Det vil således være klart at stålbjelken i henhold til oppfinnelsen eller detaljene ved denne ikke trenger å være nøyaktig slik som vist i figurene, og løsninger av en annen type er også mulig. The above stated embodiment of the invention is not intended to limit the invention in any way, as the invention can be modified freely within the scope of the patent claims. It will thus be clear that the steel beam according to the invention or the details thereof do not need to be exactly as shown in the figures, and solutions of another type are also possible.
