Abstract

The invention relates to floor beam comprising two ribs (3), which fix a first and a second flange (1, 2) at a distance from each other, where the two ribs (3) and the first flange (1) make a profile formed in one piece, essentially of U-shape, and that at least one groove (4a) formed in each rib (3) extends in the longitudinal direction of the beam (5).

Description

5142 615 Detta löses genom en bjälklagsbalk, avi inledningen angivet slag, där de båda liven och den första flänsen utgör en i ett stycke bildad profil, med i huvudsak U-form, och att åtminstone en i varje liv bildad lilla sträcker sig i balkens längdriktning och att vinkeln a mellan livet och normalen mot den andra flänsen är mellan 0 och 45 grader, vari rillorna är utförda med en lcrökning, vars konvexa sidor är vända mot varandra och den andra flänsen utgör en upplagsyta för bjälklagselement. 5142 615 This is solved by a joist beam, of the type indicated in the introduction, where the two webs and the first end form a one-piece profile, with a substantially U-shape, and that at least one small formed in each web extends in the longitudinal direction of the beam. and that the angle α between the waist and the normal towards the other end is between 0 and 45 degrees, wherein the grooves are made with a curve, the convex sides of which are facing each other and the other end forms a support surface for floor elements.

Bjälklagsbalken innefattar vidare, för att öka hållfastheten och vridstyvheten hos den- samma, ett eller flera bandformiga förstärkningselement, anordnade vid den första flänsen. Den andra flänsen fimgerar även som stöd för ett eller flera betongelement.The floor beam further comprises, in order to increase the strength and torsional rigidity of the same, one or fl your band-shaped reinforcing elements, arranged at the first fl end. The other end also functions as a support for one or more of your concrete elements.

Med fördel kan en eller flera iillor anordnas i den första flänsen, i balkens längd- riktning, och därmed ersätta det vid den första flänsen monterade bandforrniga för- stärkningselementet.Advantageously, one or more of the eyelets can be arranged in the first fl end, in the longitudinal direction of the beam, and thereby replace the band-shaped reinforcing element mounted at the first fl end.

Uppfinningen innebär att en bjälklagsbalk har åstadkommits, vilket samtidigt med sin lätta konstruktion har en stor vridstyvhet samt hög hållfasthet, som är enkelt och billigt att tillverka och som tillåter en flexibilitet vid byggandet av exempelvis en flervånings- byggnad.The invention means that a floor beam has been achieved, which at the same time as its light construction has a high torsional rigidity and high strength, which is simple and inexpensive to manufacture and which allows flexibility in the construction of, for example, an upstairs building.

Uppfinningen innebär vidare att ett baselement har åstadkommits, det vill säga den i ett stycke bildade profilen med i huvudsak U-form, vilket baselement utgör en grund- konstruktion i själva bjälklagsbalken. En grundkonstruktion, vilken kan tillverkas i stora serier med ett fåtal dimensioner och vilken kan påbyggas efter behov.The invention also means that a base element has been achieved, i.e. the one-piece beam with a substantially U-shape, which base element constitutes a basic construction in the floor beam itself. A basic construction, which can be manufactured in large series with a few dimensions and which can be added as needed.

Uppfinningen kommer närmare beskrivas i form av två utföringsexempel med hänvis- ning till bifogade figurer, vari fig.1 visar en perspektivvy av en bjälklagsbalk enligt uppfinningen, i en första ut- töringsfoim, 20 25 30 5134 615 fig. 2 visar en perspektivvy av en bjälklagsbalk enligt uppfirmingen, i en andra ut- föringsfonn, och fig. 3 visar ett tvärsnitt av en i ett stycke bildad profil med i huvudsak U-form, enligt den första utföringsformen.The invention will be described in more detail in the form of two embodiments with reference to the attached urer gures, in which fi g.1 shows a perspective view of a floor beam according to the invention, in a first embodiment, 20 25 30 5134 615 fi g. 2 shows a perspective view of a floor beam according to the invention, in a second embodiment, and fi g. 3 shows a cross section of a one-piece profile with a substantially U-shape, according to the first embodiment.

Fig. 1 visar en bjälldagsbalk 5, innefattande en i ett stycke bildad profil i huvudsak med U-form, enligt en första utiöringsform. Bjälklagsbalken är i utföringsexemplet placerat med en första fläns l uppåt. Den första flänsen 1 utgör balkens 5 botten.Fig. 1 shows a bell day beam 5, comprising a one-piece profile substantially with a U-shape, according to a first embodiment. In the exemplary embodiment, the joist beam is placed with a first fl even l upwards. The first 1 end 1 forms the bottom of the beam 5.

Utifiån den första flänsen 1 utgår två utåt lutande liv 3. Balken 5 uppvisar vidare en lilla 4a i vardera livet 3. Balkämnet kan exempelvis vara plåt.Outside the first 1 end 1 there are two outwardly sloping webs 3. The beam 5 further has a small 4a in each web 3. The beam blank can, for example, be sheet metal.

Vid den första flänsen 1 har ett metallband 7 fastsvetsats, för att ge bjälklagsbalken en större lastupptagningsförmåga. Även andra bandmaterial, kan här med fördel användas.At the first end 1 a metal strip 7 has been welded on, in order to give the floor beam a greater load-bearing capacity. Other tape materials can also be used to advantage here.

Likaså kan så kallade studs (inte visade) fastsvetsas på ovansidan av den första flänsen l och därmed i kombination med betong, som gjuts över bjälklagsbalken vid byggna- tionen, ge balken 5 den önskade lastupptagnirrgsförmågan.Likewise, so-called bounces (not shown) can be welded to the top of the first ridge 1 and thus in combination with concrete, which is cast over the floor beam during construction, give the beam 5 the desired load-bearing capacity.

Vid livens 3 fria kanter har en andra fläns 2 fastsvetsats, för att dels utgöra stöd för betongelement (inte visade), dels öka balkens lastupptagningsfönnåga. Det kan vara ett metallband, bandstål eller något annat bandelement. Den andra flänsen 2 betecknas hädanefter även som ett bandformigt element.At the 3 free edges of the life, a second fl than 2 has been welded, to partly provide support for concrete elements (not shown), and partly increase the load-bearing capacity of the beam. It can be a metal strip, strip steel or some other strip element. The second axis 2 is hereinafter also referred to as a band-shaped element.

Vinkeln ot mellan nonnalen till flänsen 2 och livet 3 kan vara mellan 0 och 45 grader, men är företrädesvis mellan 4 och 10 grader. En viss lutning är i många fall önskvärd, varvid betong lättare kan transporteras ner mellan livens 3 utsidor och nämnda betong- elements (inte visade) kortsidor. Lutningen i sig, innebär även en ökad hållfasthet hos balken, enär en valvverkan åstadkommes. Vinkeln ot kan vara upp till 45 grader.The angle ot between the nonnal to fl änsen 2 and the waist 3 can be between 0 and 45 degrees, but is preferably between 4 and 10 degrees. A certain slope is in many cases desirable, whereby concrete can be more easily transported down between the 3 outer sides of the life and the short sides of the said concrete elements (not shown). The slope itself also means an increased strength of the beam, since an arching effect is achieved. The angle ot can be up to 45 degrees.

Dock bestäms, utav den andra flänsens 2 bredd, en övre gräns på vinkeln ot, eftersom uppläggningsytor 10 för bjälklagselementen (inte visade) erfordras. Uppfinningen har 20 25 30 5144615 den fördelen att endast de bandformiga elementens 2, 7 dimension behöver anpassas efter den lastupptagningsförmåga som bjälklagsbalken skall ha.However, from the width of the other end 2, an upper limit of the angle ot is determined, since support surfaces 10 for the floor elements (not shown) are required. The invention has the advantage that only the dimensions of the strip-shaped elements 2, 7 need to be adapted to the load-bearing capacity of the floor beam.

Tjockleken på plåten hos profilen med i huvudsak U-form, är företrädesvis mellan 4 och 8 millimeter och tjockleken på den andra flänsen 2, vilken har sammansvetsas med livens 3 fria kanter, år företrädesvis mellan 10 och 20 millimeter och kan variera uti- från den belastning som bj älklagsbalken kommer att utsättas för.The thickness of the plate of the profile with a substantially U-shape, is preferably between 4 and 8 millimeters and the thickness of the other end 2, which has been welded together with the 3 free edges of the web, is preferably between 10 and 20 millimeters and can vary from the load to which the floor beam will be exposed.

Livens 3 höjd kan med fördel varieras utifrån betongelementens (inte visade) tjocklek och önskad lastupptagningsförmåga hos balken 5. De mått som, vid tillverkningen av balken, kan vara konstanta, är den första flänsens 1 bredd och avståndet från rillorna 4a till den första flänsen 1. Avståndet mellan rillorna 4a och den andra flänsen 2 kan med fördel varieras utifrån balkämnets bredd, det vill säga höjden på bjälklagsbalken kan bestämmas genom plåtens bredd, utan att inställningen av produktionsanordningen, exempelvis ett rullpressverktyg, för balktillverkningen behöver ändras.The height of the web 3 can advantageously be varied on the basis of the thickness of the concrete elements (not shown) and the desired load-bearing capacity of the beam 5. The dimensions which, in the manufacture of the beam, can be constant are the width of the first groove 1 and the distance from grooves 4a to the first groove 1 The distance between the grooves 4a and the other end 2 can advantageously be varied according to the width of the beam blank, i.e. the height of the floor beam can be determined by the width of the plate, without the setting of the production device, for example a roller press tool, for beam production.

Med fördel är rillorna 4a utförda inåt med en krökning, vars konvexa sidor är vända mot varandra, för att betongen lättare ska kunna transporteras mellan liven och betong- elementen (ej visade).Advantageously, the grooves 4a are made inwards with a curvature, the convex sides of which face each other, so that the concrete can be more easily transported between the webs and the concrete elements (not shown).

Fig. 2 visar en andra utföringsform enligt uppfinningen. Det, enligt den första ut- föringsforrnen i fig. 1, monterade metallbandet 7 har härvidlag ersatts av en lilla 4b i den första flänsen 1, vilken rilla 4b sträcker sig i balkens 5 längdriktning.Fig. 2 shows a second embodiment according to the invention. That, according to the first embodiment in fi g. 1, mounted metal strip 7 has in this respect been replaced by a small 4b in the first end 1, which groove 4b extends in the longitudinal direction of the beam 5.

Rillans 4b uppgift är att ge bjälklagsbalken en större lastupptagningsförniåga, samt att ge de egenskaper, som eftersträvas i den första utföringsformen. Detta innebär sam- tidigt en míndre materialåtgång vid tillverkningen av bjälklagsbalken. Likaså blir till- verkningskostnaden lägre.The task of the groove 4b is to give the floor beam a greater load-bearing capacity, and to give the properties which are sought in the first embodiment. At the same time, this means less material consumption in the manufacture of the floor joists. The production cost will also be lower.

Fig. 3 visar ett tvärsnitt av en i ett stycke bildad profil i huvudsak med U-form, enligt det första utföringsexemplet. 515; 615 Profilen är utförd med en väsentligen platt första fläns 1. Figuren visar de utförda rillorna 4a i liven 3. Rilloma 4a är med fördel vända inåt. Självfallet kan antalet rillor 4a varieras och även utföras i plåtbalkens första fläns 1.Fig. 3 shows a cross-section of a one-piece profile formed substantially in a U-shape, according to the first embodiment. 515; 615 The profile is made with a substantially flat first end 1. The figure shows the made grooves 4a in the web 3. The grooves 4a are advantageously turned inwards. Of course, the number of grooves 4a can be varied and also made in the first beam 1 of the sheet metal beam 1.

Enligt de visade utföringsformema, har profilen formen av ett U, men denna form kan naturligtvis varieras. Exempelvis kan liven 3 vara svagt lcrökta och den första flänsen l kan vara buktad inåt.According to the embodiments shown, the profile has the shape of a U, but this shape can of course be varied. For example, the web 3 may be slightly curved and the first edge 1 may be curved inwards.

Bjälklagsbalken kan, naturligtvis, vara belägen i andra positioner än traditionella bjälk- lag. Det vill säga, utgöra stödelement i väggar och i lutande konstruktioner.The joist beam can, of course, be located in positions other than traditional joists. That is, constitute supporting elements in walls and in sloping structures.

Den i ett stycke utförda profilen, enligt utföringsfonnerna, kan till exempel tillverkas med ett rullpressverktyg eller ett kantpressverktyg.The one-piece pro, according to the embodiments, can be manufactured, for example, with a roller press tool or an edge press tool.
