Description

461 108 10 15 20 25 30 35 40 skruv såsom indikeras med 43 på flera ställen och det bildade plåtdäcket användes som förlorad form för en platsgjuten \ betongplatta 44. I underkant på betongplattan 44 formar den trapetsprofilerade plåten balkar som på grund av att sekundär- balkarnas 16-20 överflänsar 42 är på en betydligt lägre nivå än primärbalkarnas överflänsar 23 kommer att till en väsentlig del vara belägna under primärbalkarnas överflänsar 23. Dessa betongbalkar har alla givits samma beteckning 47. Betongplattan 44 är sprickarmerad med ett armeringsnät 46. Plåtformen kring betongplattans 44 balkar 47 fungerar som dragarmering, men balkarna kan ytterligare förstärkas med längsgående armerings- stänger 48. 461 108 10 15 20 25 30 35 40 40 as indicated by 43 in several places and the formed sheet metal deck was used as a lost form for a cast-in-place concrete slab 44. At the lower edge of the concrete slab 44 the trapezoidal profiled sheet forms beams which 16-20 upper flanges 42 are at a much lower level than the upper flanges 23 of the primary beams will to a substantial extent be located below the upper flanges 23 of the primary beams. These concrete beams have all been given the same designation 47. The concrete slab 44 is crack reinforced with a reinforcing mesh 46. beams 47 act as tensile reinforcement, but the beams can be further reinforced with longitudinal reinforcement bars 48.

Armeringen i betongplattan 44 och dess balkar 47 är synnerligen enkel och går snabbt, varför byggnadstiden blir kort.The reinforcement in the concrete slab 44 and its beams 47 is extremely simple and fast, so that the construction time is short.

Primärbalkarnas 12 överflänsar är bàgformade i ett centralt parti beläget mellan sekundärbalkarna såsom framgår av fig 1.The upper flanges of the primary beams 12 are arcuate in a central portion located between the secondary beams as shown in Fig. 1.

Bågformen är väsentligen den som plåtarna 35,36,37 skulle få på grund av egenvikten om de skulle uppläggas balanserande enbart på ett mittstöd. Utanför sekundärbalkarna 17 och 19 är överflänsarna 23 raka men lutande. Anslutningen mellan den bågformade delen och de båda raka delarna är lämpligen asymptotisk. Infästningen av sekundärbalkarna 16-20 ansluter till primärbalkarnas överflänsars bågform. Denna bàgform underlättar läggningen av plåten och medför lämplig lutning för ett parkeringsdäck. Dessutom får man en förtjockning av betongen mot mitten om betongens överyta lägges rak mot en ås över primärbalkarnas mitt, såsom visas, vilket är fördelaktigt för parkeringshus, eftersom körbanorna lämpligen förläggas där. Mellan primärbalkarnas 12,13 ändar vinkelrätt mot primärbalkarna löper avvattningsrännorna 22 anslutna till stuprör i anslutning till primärbalkarnas stöd- pelare 15. Avvattningsrännorna avvattnar dels betongens överyta, men också formplåten om det skulle bildas vatten mellan form- plåten och betongen. Plåten utgör således ett extra tätskikt.The arcuate shape is essentially that which the plates 35,36,37 would have due to their own weight if they were to be laid balancing only on a central support. Outside the secondary beams 17 and 19, the upper flanges 23 are straight but inclined. The connection between the arcuate part and the two straight parts is suitably asymptotic. The attachment of the secondary beams 16-20 connects to the arcuate shape of the upper beams of the primary beams. This arch shape facilitates the laying of the sheet metal and provides a suitable slope for a parking deck. In addition, a thickening of the concrete towards the center is obtained if the upper surface of the concrete is laid straight against a ridge above the center of the primary beams, as shown, which is advantageous for parking garages, since the carriageways are conveniently located there. Between the ends of the primary beams 12,13 perpendicular to the primary beams run the drainage gutters 22 connected to downpipes adjacent to the primary beams support pillars 15. The drainage gutters drain both the upper surface of the concrete, but also the mold plate if water were to form between the mold plate and the concrete. The plate thus constitutes an extra sealing layer.

I fig 3 visas en alternativ utföringsform i vilken den trapetskorrugerade plåten har en överfläns 50 som är så bred att < den helt täcker primärbalkarnas överflänsar 23. Överflänsen 50 är tvärembosserad för att få styvhet och skarvarna 51,52 mellan plåtarna är uppstående mitt i underflänsarna och sträcker sig åtminstone till överflänsens 50 nivå eller något högre såsom visas i figuren. Varje plåt består således av en halv smal 10 461 108 underfläns 53,54 på var sida om en bred överfläns 50. De uppstàende skarvarna bildar dragarmering för betongen. En underfläns 53 pà en plàt och en underfläns 54 pà en bredvid- liggande plåt bildar således tillsammans en fullständig under- fläns. En sprickarmering i form av ett nät 46 såsom visat i fig 2 bör dock lämpligen användas.Fig. 3 shows an alternative embodiment in which the trapezoidal corrugated plate has an upper flange 50 which is so wide that it completely covers the upper flanges 23 of the primary beams. The upper flange 50 is cross-embossed to obtain rigidity and the joints 51,52 between the plates are in the middle of the lower flanges and extends at least to the level of the upper flange 50 or slightly higher as shown in the figure. Each plate thus consists of a semi-narrow lower flange 53,54 on each side of a wide upper flange 50. The upright joints form tensile reinforcement for the concrete. A lower flange 53 on a plate and a lower flange 54 on an adjacent plate thus together form a complete lower flange. However, a crack reinforcement in the form of a net 46 as shown in Fig. 2 should suitably be used.

Plàten i de uppstáende skarvarna kan vara försedd med smá bulor för att ge samverkan med betongen. Detta utförande pà plàtformen medför en än mer förkortad byggtid.'The plate in the standing joints can be provided with small bumps to provide interaction with the concrete. This design of the platform entails an even shorter construction time. '
