Description
15 20 25 30 35 40 iso? 062 nas ingjutna randdel och den omgivande betongen, och vidare an- visar uppfinningen att den ingjutna plåtbalkdelen inte har nå- gon egentlig egen kraftupptagande fläns, utan enbart har för- setts med medel som överför krafterna från plåtbalkens liv till den rutarmerade betongplattan. 15 20 25 30 35 40 iso? The cast edge part and the surrounding concrete, and further the invention indicates that the cast sheet metal part does not have its own actual force-absorbing flange, but has only been provided with means which transfer the forces from the life of the sheet metal beam to the window-reinforced concrete slab.
Enligt en annan aspekt på uppfinningen har plåtbalkarna därvid en mycket låg egen stabilitet, dvs. att plåtbalkarna är slanka och veka åtminstone innan de fastgjutits i betonglattan.According to another aspect of the invention, the sheet metal beams then have a very low stability of their own, i.e. that the sheet metal beams are slender and fold at least before they are cast in the concrete slab.
Vid platstillverkning av bjälklag, kan därvid plåtbalkarna överhöjas, dvs. krökas till en konvex krökning uppåt, och bibe- hållas i sådan överhöjning under gjutningsstadiet. Överhöjning- en kan erhållas antingen genom stämp stående på undervarande bärverk eller ett spännverk som anbringas på varje balk före dess montering på platsen. I det stadiet skall spännverket vara spänt endast till antydan om överhöjning. Uppspänningen för den slutgiltiga överhöjningen utföres när alla formelement monte- rats. Både stämp och spännverk skall vara så utformade att de håller kvar balken i det läge den skall ha i ingjutningsläget.In the case of on-site production of floors, the sheet metal beams can be raised, ie. is curved to a convex curvature upwards, and is maintained in such an elevation during the casting stage. The elevation can be obtained either by a stamp standing on the underlying support structure or a tensioning device which is applied to each beam before its mounting on site. At that stage, the clamping device shall be tensioned only to indicate an increase. The clamping for the final elevation is performed when all mold elements have been mounted. Both the piston and the tensioning device must be designed in such a way that they hold the beam in the position it is to be in the casting position.
Gjutformsbottnar/formelement kan därvid temporärt fästas mellan de överhöjda balkarnas liv, på en nivå under plåtbalkarnas övre rand. Gjutformsbottnarna bildar då ett gångbart golv, och be- tongplattans rutarmering kan monteras på plåtbalkarnas övre randdelar som alltså håller upp rutarmeringen från gjutformens botten, så att rutarmeringen kan ingjutas exempelvis vid be- tongplattans halva höjd/tjocklek. Överhöjningen tjänar till att säkerställa att plåtbalkar- nas material utnyttjas hållfasthetsmässigt på bästa sätt, då betongplattan med pàgjutna balkar efter betongens hårdnande un- der inverkan av egenvikten sjunker ned till ett önskat plant horisontellt läge. Detta ställer emellertid stora krav pà plåt- balkarnas infästning i betongen, med särskild hänsyn till be- tongplattans ringa höjd.Mold bases / mold elements can then be temporarily fastened between the life of the raised beams, at a level below the upper edge of the sheet metal beams. The mold bases then form a walkable floor, and the window reinforcement of the concrete slab can be mounted on the upper edge parts of the sheet metal beams which thus hold up the window reinforcement from the bottom of the mold, so that the window reinforcement can be molded in at half the height / thickness of the concrete slab. The elevation serves to ensure that the material of the sheet metal beams is utilized in terms of strength in the best way, as the concrete slab with cast beams after the hardening of the concrete under the influence of the dead weight drops down to a desired flat horizontal position. However, this places great demands on the attachment of the sheet metal beams to the concrete, with special regard to the small height of the concrete slab.
Enligt uppfinningen föredras därvid att anordna urtag- ningar i plåtbalkarnas över randdel för lokalisering av stänger tillhörande rutarmeringens ena stångskara. Vidare föredras att anordna tungor och/eller dubbar som sträcker sig vinkelrätt ut från balkarnas ingjutna livdelar. Speciellt föredragna utfö- ringsformer av medlen för att etablera en god vidhäftning/ förankring av plåtbalkarna i betongplattan framgår av patent- kraven och utföringsexemplen. 10 15 20 25 30 35 40 3 " 507 062 Gjutformsbottnarna kan avlägsnas efter betongens hàrdnan- de.According to the invention, it is then preferred to arrange recesses in the upper edge part of the sheet metal beams for locating rods belonging to one of the rod reinforcement of the window reinforcement. Furthermore, it is preferred to arrange tongues and / or studs which extend perpendicularly from the cast-in body parts of the beams. Particularly preferred embodiments of the means for establishing a good adhesion / anchoring of the sheet metal beams in the concrete slab appear from the patent claims and the exemplary embodiments. 10 15 20 25 30 35 40 3 "507 062 The mold bases can be removed after the concrete has hardened.
Ehuru överhöjningstekniken är särskilt gynnsam med avse- ende på tillverkning av bjälklag, bör det stå klart att uppfin- ningen kan användas utan sàdan överhöjningsteknik, exempelvis för framställning av väggelement bestående av en rutarmerad be- tongplatta med pàgjutna förstyvningsplàtbalkar.Although the raising technique is particularly favorable with regard to the manufacture of floors, it should be clear that the invention can be used without such a raising technique, for example for the production of wall elements consisting of a reinforced concrete slab with cast stiffening plate beams.
Uppfinningen kommer i det följande att beskrivas i exem- pelform med hänvisning till den bilagda ritningen.The invention will be described in the following in an exemplary form with reference to the accompanying drawing.
Fig. 1 visar schematiskt ett vertikalsnitt genom ett bjälklag enligt uppfinningen; Fig. 2 visar en sektion tagen utmed linje A-A i fig. 1; Fig. 3 visar en schematisk vy tagen utmed linje III-III i fig. 2; Fig. 4 visar ett alternativt utförande av det uppfinningsen- liga bjälklaget, i en sektion motsvarande A-A i fig. 1; Fig. 5 visar en schematisk vy tagen utmed linje V-V i fig. 4; Fig. 6 visar en schematisk sektionsvy tagen utmed linje VI-VI i fig. 5; Fig. 7 illustrerar schematiskt överhöjning av en balk/bjälke i bjälklaget enligt uppfinningen.Fig. 1 schematically shows a vertical section through a floor according to the invention; Fig. 2 shows a section taken along line A-A in Fig. 1; Fig. 3 shows a schematic view taken along line III-III in Fig. 2; Fig. 4 shows an alternative embodiment of the floor according to the invention, in a section corresponding to A-A in Fig. 1; Fig. 5 shows a schematic view taken along line V-V in Fig. 4; Fig. 6 shows a schematic sectional view taken along line VI-VI in Fig. 5; Fig. 7 schematically illustrates raising of a beam / beam in the floor layer according to the invention.
Enligt uppfinningen bygges ett bjälklag av parallellt riktade parallellt orienterade plåtbalkar 1 omfattande ett ver- tikalt orienterat liv 10 som i sin undre ände har en fläns 11.According to the invention, a floor is built of parallel-oriented parallel-oriented sheet metal beams 1 comprising a vertically oriented web 10 which has a flange 11 at its lower end.
Flänsen 11 kan med fördel sträcka sig ut från enbart ena sidan av livet 10. Balkarna 1 har ingen egen övre fläns vid livets 10 övre rand. En betongplatta 20 visas pàgjuten på övre randdelar- na av balkarna 1. För den sakens skull monteras formluckor 24 mellan närliggande balkar 1 på ett ringa avstånd under deras över rand. Formluckorna 24 kan monteras på plats efter det att balkarna 1 inplacerats med korrekt inbördes avstånd, och såsom visas kan formluckorna 24 uppbäras pà kilar/sprintar 25 som är lösbart monterade i tillhörande sprintöppningar genom liven 10, så att formluckorna 24 enkelt kan demonetras efter betongens hàrdnande.The flange 11 can advantageously extend from only one side of the web 10. The beams 1 do not have their own upper flange at the upper edge of the web 10. A concrete slab 20 is shown cast on the upper edge portions of the beams 1. For that matter, mold gaps 24 are mounted between adjacent beams 1 at a small distance below their upper edge. The mold doors 24 can be mounted in place after the beams 1 have been placed at the correct mutual distance, and as shown the mold doors 24 can be supported on wedges / pins 25 which are releasably mounted in associated pin openings through the webs 10, so that the mold doors 24 can be easily demounted after concrete hardening. .
Vidare visas på fig. 1 att en rutarmering är ingjuten i betongplattan 20. Rutarmeringen omfattar en skara av stänger 31 som sträcker sig parallella med balkarna 1, och en skara av 10 15 20 25 30 35 40 507 062 stänger 32 vilka sträcker vinkelräta mot stängerna 31. Rutarme- ringen 31, 32 är belägen ungefär vid plattans 20 halva höjd, varvid stängerna 32 med fördel är uppurna av balkarnas 1 övre randdelar.Furthermore, it is shown in Fig. 1 that a window reinforcement is cast in the concrete slab 20. The window reinforcement comprises a group of bars 31 extending parallel to the beams 1, and a group of bars 32 which extend perpendicular to the bars. 31. The window reinforcement 31, 32 is located approximately at half the height of the plate 20, the bars 32 being advantageously supported by the upper edge parts of the beams 1.
Med hänvisning till fig. 2 kan man se att livet 10 i sin övre randdel har uppåt öppna urtagningar 14 vilka kan emotta stänger 32. Stängerna 31 kan placeras ovanpå stängerna 32. För att tillhandahålla en vidhäftning/förankring för plåtlivet 10 med avseende på rörelse i balkens 1 längdriktning relativt be- tongen, är öppningar 40 upptagna i livet 10 nära dess övre rand, och är dubbar 41 genomstuckna till sin halva längd genom öppningarna 40. Dubbarna 41 skjuter ut ungefär lika långt på vardera sidan om livet 10. Urtagningarna 14 kan vara bildade så att dess ena kant och botten är formade som snitt genom livet 10, varvid den resulterande tungan 15 är omböjd 90° från livets 10 plan, för att ytterligare förbättra vidhäftningen mellan balken 1 och betongplattan 20.Referring to Fig. 2, it can be seen that the web 10 in its upper edge portion has upwardly open recesses 14 which can receive rods 32. The rods 31 can be placed on top of the rods 32. To provide an adhesion / anchoring to the sheet metal web 10 with respect to movement in the longitudinal direction of the beam 1 relative to the concrete, openings 40 are received in the web 10 near its upper edge, and studs 41 are pierced to their half length through the openings 40. The studs 41 project approximately equally far on each side of the web 10. The recesses 14 can be formed so that one edge and bottom are formed as a section through the web 10, the resulting tongue 15 being bent 90 ° from the plane of the web 10, to further improve the adhesion between the beam 1 and the concrete slab 20.
Med hänvisning till fig. 4 visas ett alternativ till ur- tagningarna 14 och tungorna 15 enligt fig. 2, 3. Om vid först tittar på fig. 8 som illustrerar det övre randpartiet av plåt- balkens 1 liv 10, kan man se att slitsar eller inklipp 18 an- ordnats på regelbundna avstånd längs livets 10 överkant. Dessa inklipp 18 är vinkelräta mot balkens 1 längdriktning och sträcker sig till lika djup. Vidare visas på fig. 8 streckade linjer 19 som bildar en konstant vinkel mot inklippet 18 på vardera sidan om detta. Linjerna 19 utgår från bottenregionen av inklippet 18 och markerar den axel kring vilken de av in- klippen 18 och linjerna 19 bildade tungorna 16 som visas på fig. 4-6. Man kan se att tungorna på vardera sidan om ett in- klipp 18 har vridits åt olika håll.Referring to Fig. 4, an alternative to the recesses 14 and tongues 15 of Figs. 2, 3 is shown. If you first look at Fig. 8 which illustrates the upper edge portion of the web 10 of the sheet metal beam 1, it can be seen that slits or cut-outs 18 are arranged at regular intervals along the upper edge of the web 10. These notches 18 are perpendicular to the longitudinal direction of the beam 1 and extend to equal depths. Furthermore, Fig. 8 shows broken lines 19 which form a constant angle to the notch 18 on each side thereof. The lines 19 start from the bottom region of the notch 18 and mark the axis around which the tongues 16 formed by the notches 18 and the lines 19 are shown in Figs. 4-6. You can see that the tongues on each side of a cut-in 18 have been turned in different directions.
Genom att tungorna 16 utböjts kring sluttande böjnings- linjer/böjningsaxlar 19 kommer deras överkant 17 efter utvrid- ningen att slutta nedåt såsom bäst framgår av fig. 6, varvid tungans 16 kantlinje som definieras av mittlinjen 18 bildar en underskuren kantlinje. Genom att man placerar armeringsstänger- na 31 ovanpå stängerna 32 i kontakt med den underskurna kanten 18, kommer stängerna 31 även att bilda en mekanisk låsning mot utdragning av livet 10 i riktning nedåt, om betongplattan och balkarna utsättes för en kraftig vertikal nedåtriktad belast- ning. Såsom framgår av fig. 5 och 6 kan de båda armeringsstäng- lO 15 20 25 30 5 L 507 oez erna 31 som samverkar med de båda fránvända kanterna 18 pà ett balkliv 10 vara inbördes kopplade med ett fjäderelement 50. Sá- som schematiskt illustreras på fig. 5 och 6, erbjuds en mycket enkel montering av detta par av armeringsstänger 31, speciellt som tungornas kantytor 17 bildar en expanderingskil med avseen- de på monteringen av de av fjädrar 50 sammanhàllna stängerna 31. Stàngparet 31 kan sålunda centreras pà den rygg som defini- eras av skärningen av kanterna 17 i fig. 6 och helt enkelt tryckas nedåt, varvid stängerna 31 kilas isär. När stängerna 31 sedan har kommit in på kantytorna 18, dras de automatiskt nedåt inåt till korrekt läge av fjädrarna 50 och kvarålles på plats fram till gjutningen av betongplattan 20.As the tongues 16 are bent around sloping bending lines / bending axes 19, their upper edge 17 will rotate downwards after the rotation, as best seen in Fig. 6, the edge line of the tongue 16 defined by the center line 18 forming an undercut border. By placing the reinforcing bars 31 on top of the bars 32 in contact with the undercut edge 18, the bars 31 will also form a mechanical lock against pulling out the web 10 in the downward direction, if the concrete slab and beams are subjected to a strong vertical downward load. . As can be seen from Figs. 5 and 6, the two reinforcing rods L 507 oezs 31 which cooperate with the two opposite edges 18 of a beam web 10 can be interconnected with a spring element 50. As schematically illustrated on Figs. 5 and 6, a very simple mounting of this pair of reinforcing bars 31 is offered, especially as the edge surfaces 17 of the tongues form an expansion wedge with respect to the mounting of the bars 31 held by springs 50. The bar pair 31 can thus be centered on the back which is defined by the cutting of the edges 17 in Fig. 6 and is simply pushed downwards, the rods 31 being wedged apart. When the rods 31 have then entered the edge surfaces 18, they are automatically pulled downwards inwards to the correct position by the springs 50 and retained in place until the casting of the concrete slab 20.
Balkarna bör normalt överhöjas i samband med etablering av ett bjälklag. Med överhöjning avses att balkarna 1 elastiskt ökas till uppåt välvd form och hålles i sådan form ända tills den pàgjutna betongplattan 20 har hàrdnat, varefter balkarna 1 frisläppes och elastiskt kan återgå under inverkan av balkarnas och betongplattans 20 egenvikt, mot ett rakt tillstànd.The beams should normally be raised in connection with the establishment of a floor. By raising is meant that the beams 1 are elastically raised to an upwardly curved shape and held in such a shape until the cast concrete slab 20 has hardened, after which the beams 1 are released and can return elastically under the influence of the beams and concrete slab 20, against a straight condition.
Fig. 7 illustrerar överhöjningsprincipen.En böjstyv balk 60 anslutes med tryckbelastade strävor 1 till två symmetriskt belägna centala punkter på balken 1. Ãndarna av balken 1 anslu- tes med dragstag 62 till den böjstyva överhöjningsbalken 60.Fig. 7 illustrates the bending principle. A bending rigid beam 60 is connected with pressure-loaded struts 1 to two symmetrically located central points on the beam 1. The ends of the beam 1 are connected with tie rods 62 to the bending rigid bending beam 60.
Genom justering av dragstagens 62 längd och strävornas 61 pla- cering kan balken 1 ges en lämplig överhöjning.By adjusting the length of the tie rods 62 and the position of the struts 61, a beam can be given a suitable elevation.
För att åter hänvisa till fig. 1 ser man att J-formade bjälklagsbalkar 1 underlättar anslutning av stagen 61, 62 till balkarna 1, varvid stagen 61, 62 och den styva balken 60 även kan tjäna till att stabilisera den tillhörande balken 1 så att denna bibehàlles rak och med vertikalt liv under de belastning- ar som uppkommer i samband med byggande av bjälklaget.Referring again to Fig. 1, it is seen that J-shaped floor beams 1 facilitate connection of the struts 61, 62 to the beams 1, whereby the struts 61, 62 and the rigid beam 60 can also serve to stabilize the associated beam 1 so that this maintained straight and with vertical life under the loads that arise in connection with the construction of the floor.
Med avseende på fig. 1 inses att man med fördel samman- häller balkarna 1 inbördes till tät kontakt mot gjutformluckor- na 24, så att läckage av betong inte uppträder invid balkarna 1, och så att balkarna 1 får korrekt inbördes avstånd.With respect to Fig. 1, it will be appreciated that the beams 1 are advantageously joined together for close contact with the mold hatches 24, so that leakage of concrete does not occur next to the beams 1, and so that the beams 1 are correctly spaced apart.
