Keksintö liittyy palkkiin, jonka varaan voidaan tukea rakennuksen 10 kantavat rakenteet, kuten ontelolaatat, liitto- ja kuorilaatat, paikallavalu yms. Palkki täytetään saumavalun tai muun betonivalun yhteydessä betonilla, jonka kovettumisen jälkeen palkki toimii liittorakenteena. Tällaiset palkit ovat nykyään varsin tunnettuja elementtirakenteiden yhteydessä. Esimerkkeinä alalla tunnetuista ratkaisuista voidaan mainita Fl-julkaisuissa 85745 ja 92089 kuvatut rat-15 kaisut. Liittorakenteen avulla päästään aiempaa kevyempään teräspalkkiin ja palkkia voidaan käyttää entistä pidemmällä jännevälillä.The invention relates to a beam for supporting the load-bearing structures of the building 10, such as hollow core slabs, composite and shell slabs, spot casting, etc. The beam is filled with concrete, which after curing acts as a composite structure. Such beams are nowadays quite well known in the context of elemental structures. As examples of solutions known in the art, the rat-15 variants described in Fl publications 85745 and 92089 may be mentioned. The composite structure provides a lighter steel beam and can be used for longer spans.

Aiemmin tunnetun tekniikan mukaiset ratkaisut, esimerkiksi edellä mainituista julkaisuista tunnetut ratkaisut toimivat erilaisissa rakenteissa täysin ongelmitta. Rakentamisen yhteydessä on kuitenkin syntynyt tarvetta palkille, 20 jolla on parempi leikkauskapasiteetti kuin aiemmin tunnetuilla ratkaisuilla.Prior art solutions, for example those known from the aforementioned publications, operate in various structures without any problems. However, there is a need in the construction for a beam 20 which has a better shear capacity than previously known solutions.

Keksinnön tarkoituksena on saada aikaan teräspalkki, jonka avulla **’ : aiemmin tunnetun tekniikan epäkohdat pystytään eliminoimaan. Tähän on päästy keksinnön avulla. Keksinnön mukainen teräspalkki on tunnettu siitä, et- • « · tä ainakin toinen uumaosa on muodostettu levyosasta, joka muodostuu kah- *:**: 25 desta palkin pituussuuntaisesta osasta, jotka ovat kulmassa toisiinsa nähden ja että levyosa on kiinnitetty pohjalevyyn ja yläosaan niin, että uumaosan ala- :***: osa on kulmassa pohjalevyyn nähden ja yläosa olennaisesti kohtisuorassa • · · pohjalevyyn nähden.The object of the invention is to provide a steel beam by means of which the disadvantages of the prior art can be eliminated. This has been achieved by the invention. The steel beam according to the invention is characterized in that at least one web portion is formed by a plate portion consisting of two *: **: 25 longitudinal portions of the beam which are at an angle to each other and that the plate portion is secured to the base plate and top that the lower portion of the web portion: ***: is at an angle to the base plate and the upper portion is substantially perpendicular to the base plate.

Keksinnön etuna aiemmin tunnettuun tekniikkaan verrattuna on en- • · · s·'.' 30 nen kaikkea se, että keksinnön mukaisen palkin leikkauskapasiteetti on olen- *:* naisella tavalla suurempi kuin aiemmin tunnetun tekniikan mukaisen palkin leikkauskapasiteetti. Keksinnön mukainen teräspalkki on myös yksinkertainen, jolloin keksinnön käyttöönotto ja käyttö muodostuu edulliseksi. Keksinnön etu-na on edelleen se, että keksintöä voidaan muunnella tarpeen mukaan, jolloin 35 keksinnön käyttö muodostuu edulliseksi. Etuna on edelleen se, että keksinnön • · * · « 119196 2 mukaista palkkia voidaan valmistaa samoilla valmistuslinjoilla kuin aiemmin tunnettuja palkkeja.The advantage of the invention over the prior art is en- · · s · '.' It is all the more important that the shear capacity of the beam of the invention is substantially *: * larger than the shear capacity of the beam of the prior art. The steel beam according to the invention is also simple, whereby the introduction and use of the invention becomes advantageous. A further advantage of the invention is that the invention can be modified as needed, thus making use of the invention advantageous. A further advantage is that the beam according to the invention can be manufactured using the same production lines as the beams known in the art.

Keksinnön olennaisen ajatuksen mukaisesti ainakin toinen uumaosa • · · 2, 3 on muodostettu levyosasta, joka muodostuu kahdesta palkin pituussuun-täisestä osasta 2a, 2b ja vastaavasti 3a, 3b. Osat 2a, 2b ja vastaavasti 3a, 3b • # · 30 ovat kulmassa toisiinsa nähden. Uumaosan 2, 3 muodostava levyosa on kiinni- • · tetty pohjalevyyn 1 ja yläosaan 4 niin, että uumaosan 2, 3 alaosa 2a ja vastaa-vasti 3a, on kulmassa pohjalevyyn 1 nähden ja yläosa 2b ja vastaavasti 3b olennaisesti kohtisuorassa pohjalevyyn 1 nähden. Edellä mainittu rakenne nä-]·, kyy erityisen hyvin kuviossa 1. Aukot 6, jonka kautta pohjalevyn 1, uumaosien 35 2, 3 ja vaakasuoran yläosan 4 muodostamaan tilaan voidaan syöttää betonia, ***** on tässä sovellutusmuodossa sovitettu uumaosien 2, 3 yläosiin 2b, 3b.In accordance with the essential idea of the invention, at least one web portion • · · 2, 3 is formed by a plate portion consisting of two longitudinal portions 2a, 2b and 3a, 3b, respectively. The parts 2a, 2b and 3a, 3b • # · 30, respectively, are at an angle to each other. The plate portion forming the web portion 2, 3 is fixed to the bottom plate 1 and the upper portion 4 so that the lower portion 2a and the corresponding portion 3a of the web portion 2, 3 is at an angle to the bottom plate 1 and the upper portion 2b and 3b, respectively. The above structure can be seen particularly well in Figure 1. The openings 6 through which concrete can be fed into the space formed by the base plate 1, the web members 35 2, 3 and the horizontal top part 4 are adapted in this embodiment to the web members 2, 3 the upper portions 2b, 3b.

Kuvioiden 1 ja 2 sovellutusmuodossa molemmat uumaosat 2, 3 on muodostettu levyosasta, jonka osat 2a, 2b ja vastaavasti 3a, 3b ovat kulmassa toisiinsa nähden. Tällainen ratkaisu ei kuitenkaan ole ainoa mahdollinen, vaan keksintöä voidaan soveltaa myös hieman toisinkin.In the embodiment of Figures 1 and 2, both web portions 2, 3 are formed by a plate portion whose portions 2a, 2b and 3a, 3b, respectively, are at an angle to each other. However, such a solution is not the only one possible, but the invention can also be applied in slightly different ways.

5 Kuvioissa 3 ja 4 on esitetty keksinnön toinen sovellutusesimerkki.Figures 3 and 4 show another embodiment of the invention.

Kuvioissa 3 ja 4 on vastaavissa kohdissa käytetty samoja viitenumerolta kuin kuvioissa 1 ja 2.In Figures 3 and 4, the same reference numerals as in Figures 1 and 2 are used at respective positions.

Kuvioiden 3 ja 4 sovellutusmuoto eroaa kuvioiden 1 ja 2 sovellutus-muodosta siinä, että kuvioiden 3 ja 4 sovellutusmuodossa ainoastaan toinen 10 uumaosa 2 on muodostettu levyosasta, jonka osat 2a, 2b ovat kulmassa toisiinsa nähden. Tässä sovellutusmuodossa toinen uumaosa 3 suorasta aukottomasta levyosasta.The embodiment of Figures 3 and 4 differs from the embodiment of Figures 1 and 2 in that in the embodiment of Figures 3 and 4 only the second web part 2 is formed by a plate part whose parts 2a, 2b are at an angle to each other. In this embodiment, the second web portion 3 is formed from a straight, open aperture portion.

Kuvioiden 3 ja 4 mukainen sovellutusmuoto epäsymmetrinen palkki, joka on erityisen edullinen reunarakenteiden yhteydessä. Reunarakenteisiin 15 soveltuvalla palkilla tarkoitetaan sitä, että edellä kuvattu palkki muodostaa rakenteen, esimerkiksi rakennuksen jonkin tason reunan niin, että aukoton uumaosa 3 muodostaa tason reunapinnan.The embodiment of Figures 3 and 4 is an asymmetrical beam, which is particularly advantageous in connection with edge structures. By means of a beam suitable for edge structures 15, it is meant that the beam described above forms a structure, for example an edge of a plane of a building, so that the open web portion 3 forms the edge of the plane.

Keksinnön mukaista palkkia valmistettaessa on havaittu olevan edullista käyttää kylkitukia 7 ja keskitukia 8, jotka on esitetty katkoviivoin kuvi-20 ossa 3. Kylkituet 7 ja keskituet 8 voidaan sovittaa pohjalevylle 1 palkin pituussuunnassa katsottuna määrävälein. Kiinnitys voi tapahtua esimerkiksi hitsaa-maila. Kylkituet 7 on sovitettu määrittämään aukoilla 6 varustettujen uumaosi-en asennon pohjalevyn 7 suhteen ja keskituet 8 puolestaan yläosan 4 muo-dostavan levyn sijainnin. Kylkituet 7 voivat olla esimerkiksi L-muotoisia osia ku-*:·*: 25 ten kuviossa 3 on esitetty. Kylkituet ja keskituet voidaan valmistaa esimerkiksi ;\j leikkaamalla levymäisestä materiaalista.In the manufacture of the beam according to the invention, it has been found advantageous to use the side supports 7 and center supports 8, shown in broken lines in Figure 20, part 3. The side supports 7 and center supports 8 can be fitted to the base plate 1 at regular intervals. Attachment can be done, for example, by a welding club. The side supports 7 are arranged to determine the position of the web parts with openings 6 with respect to the bottom plate 7 and the center supports 8 in turn the position of the plate forming the upper part 4. The side supports 7 may, for example, be L-shaped portions as shown in Figure 3. The side supports and center supports can be made, for example, by cutting from a sheet material.

• · .···. Keksintöä voidaan soveltaa myös niin, että uumaosat 2 ja 3 leika taan palkin esikorotuksen mukaiseen kaarevaan muotoon. Tällaisessa ratkai-(V< sussa muodostuu kylkitukien ja keskitukien käyttö erityisen edulliseksi, sillä M 30 kylkituet ja keskituet tukevat ja ohjaavat uumaosia ja vaakasuoraa yläosaa erit-**:*’ täin tehokkaasti valmistusvaiheessa, jossa pohjalevy taivutetaan uumalevyjen mukaiseen kaarevuuteen. Kun pohjalevy on taivutettu edellä mainitulla tavalla niin yläosan 4 muodostava levy muotoutuu samalla keskitukien avulla oikeaan kaarevuuteen.• ·. ···. The invention can also be applied by cutting the web portions 2 and 3 into a curved shape according to the pre-rise of the beam. In such a solution, the use of side supports and center supports becomes particularly advantageous, since the M 30 side supports and center supports support and guide the web parts and the horizontal upper part - **: * 'very effectively in the manufacturing step of bending the bottom board to the curvature of the webs. in the above-mentioned manner, the plate forming the upper part 4 at the same time with the center brackets is formed into the correct curvature.

Pohjalevy 1, uumaosat 2, 3 ja yläosa 4 voidaan kiinnittää toisiinsa edullisesti hitsaamalla. Palkki voidaan tarvittaessa varustaa myös päätyosat sulkevilla päätylaipoilla. Päätyosat kiinnitetään hitsaamalla palkin päihin.The bottom plate 1, the web parts 2, 3 and the top part 4 can be fastened to one another preferably by welding. If necessary, the beam can also be provided with end flanges closing the end portions. The end sections are welded to the beam ends.

Edellä esitettyjä keksinnön sovellutusesimerkkejä ei ole mitenkään 5 tarkoitettu rajoittamaan keksintöä, vaan keksintöä voidaan muunnella patenttivaatimusten puitteissa täysin vapaasti. Näin ollen on selvä, että keksinnön mukaisen teräspalkin tai sen yksityiskohtien ei välttämättä tarvitse olla juuri sellaisia kuin kuvioissa on esitetty, vaan muunlaisetkin ratkaisut ovat mahdollisia.The foregoing embodiments of the invention are in no way intended to limit the invention, but the invention can be modified freely within the scope of the claims. Thus, it is clear that the steel beam according to the invention or its details need not necessarily be exactly as shown in the figures, but other solutions are possible.
