Description

15 20 25 30 35 ...;..._ f; 'ï-f -, g f: %W3O /f % samverkar med den färdiga konstruktionen, varvid en betydande förstärkning av fördjupningarnas effekt pà skjuvkrafterna erhålles genom utförandet en- ligt uppfinningen. 15 20 25 30 35 ...; ..._ f; 'ï-f -, g f:% W3O / f% cooperates with the finished construction, whereby a significant reinforcement of the effect of the depressions on the shear forces is obtained by the embodiment according to the invention.

Lyftbyglarnas närmast fördjupningarnas botten belägna delar är företrädesvis väsentligen vinkelräta mot bjälklagsplattans ovansida för bästa samverkan med tryckkrafter från delar av fördjupningarnas sidor.The parts of the lifting brackets closest to the bottom of the recesses are preferably substantially perpendicular to the upper side of the floor slab for best cooperation with compressive forces from parts of the sides of the recesses.

Lyftbyglarnas inre ändar kan vara förenade, exempelvis hopsvetsade, med bjälklagsplattans armering, och varje fördjupning är med fördel försedd med två bågformigt böjda armeringsjärn, som är belägna i två plan, som bildar 900 vinkel med varandra. De kan alternativt vara utförda som en integrerad del av ett av plattans längs- gående armeringsjärn.The inner ends of the lifting brackets can be joined, for example welded together, with the reinforcement of the floor plate, and each recess is advantageously provided with two arcuately curved reinforcing bars, which are located in two planes, which form 900 angles with each other. They can alternatively be designed as an integral part of one of the longitudinal reinforcement bars of the plate.

Den påstrukna betongen fungerar mellan fördjupningarna som stång med konstant normalkraft, vilket är mindre effektivt än vid kontinuerlig skjuvkraftsöverföring men skillnaderna är i allmänhet utan betydelse.The coated concrete functions between the depressions as a bar with constant normal force, which is less efficient than with continuous shear force transmission, but the differences are generally insignificant.

Uppfinningen är närmare tydliggjord i det följande un- der hänvisning till bifogade ritning, som schematiskt visar.ett utföringsexempel på en prefabricerad bjälk- lagsplatta enligt uppfinningen, och på vilken fig. 1 är en planvy av plattan, fig. 2 är en sidovy av plattan i fig. l, fig. 3 är en planvy av en del av plattan visande en fördjupning med två lyftbygeljärn och fig. 4 är en sektion efter linjen IV-IV i fig. 3.The invention is further elucidated in the following with reference to the accompanying drawing, which schematically shows an embodiment of a prefabricated floor slab according to the invention, and in which Fig. 1 is a plan view of the slab, Fig. 2 is a side view of the slab in Fig. 1, Fig. 3 is a plan view of a part of the plate showing a recess with two lifting bar irons and Fig. 4 is a section along the line IV-IV in Fig. 3.

Fig. 1 och 2 visar den med brukliga dimensioner V.. 10 15 20 prefabricerade bjälklagsplattan 1 med två vid vardera ändpartiet anordnade fördjupningar 2, i vilka lyftbyg- lar 3 sticker upp. En efter bjälklagsplattans montage avsedd pågjutning 4 med gjutbetong är markerad med en punktstreckad linje.Figs. 1 and 2 show the prefabricated floor plate 1 with customary dimensions V .. 10 with two depressions 2 arranged at each end portion, in which lifting brackets 3 protrude. A casting 4 with cast concrete intended for the installation of the floor slab is marked with a dotted line.

Fig. 1 och 2 visar den med brukliga dimensioner pre- fabricerade bjälklagsplattan 1 med två vid varandra ändpartiet anordnade fördjupningar 2, i vilka lyftbyg- lar 3 sticker upp. En efter bjälklagsplattans montage avsedd pågjutning 4 med gjutbetong är markerad med en punktstreckad linje.Figs. 1 and 2 show the floor plate 1 prefabricated with usual dimensions with two depressions 2 arranged at each other end portion, in which lifting brackets 3 protrude. A casting 4 with cast concrete intended for the installation of the floor slab is marked with a dotted line.

Fig. 3 och 4 visar en fördjupning 2 med tvâ i denna upp- skjutande, bâgformigt böjda armeringsjärn 5,6, som bil- dar en lyftbygel. Armeringsjärnens 5,6 ben 7,8 sträcker sig väsentligen vinkelrätt mot plattans 1 konventionella armering med längsgående armeringsjärn 10, med vilka järnens 5,6 änddelar 11,12, som är utåtbockade, kan vara hopsvetsade eller på annat sätt förbundna.Figs. 3 and 4 show a depression 2 with two in this projecting, arcuately bent reinforcing iron 5,6, which forms a lifting bracket. The legs 7.8 of the reinforcing bars 5.6 extend substantially perpendicular to the conventional reinforcement of the plate 1 with longitudinal reinforcing bars 10, with which the end portions 11,12 of the bars 5, 6, which are bent outwards, can be welded together or otherwise connected.
