Description
466 507 För att få en gynnsam upptagning av det moment som uppstår i infäst- ningen är armeringsjärnen, enligt en fördelaktig vidareutveckling av anord- ningen enligt uppfinningen fastskruvade i den övre delen av U-profilernas liv. 466 507 In order to obtain a favorable absorption of the moment which arises in the fastening, the reinforcing bars are, according to an advantageous further development of the device according to the invention, screwed into the upper part of the life of the U-profiles.
En såsom exempel vald utföringsform av anordningen enligt uppfinningen kommer nu att beskrivas närmare med hänvisning till bifogade ritningar, på vilka fig. 1 visar en del av en prefabricerad balkongplatta med fäste vid ena sidokanten, figur 2 visar en del av en balkongplatta med tre fästen, figur 3 visar en del av balkongplatta med fäste i sidovy, fig. 4-6 motsvarar fig. 1-3 varvid armeringsjärn är fastskruvade vid balkongens fästorgan, vilka arme- ringsjärn är avsedda att förankras i bjälklaget vid dess gjutning, fig. 7 illustrerar vissa hâllfasthetsmässiga förhållanden vid uppfinningen, fig. 8- 10 motsvarar fig. 4-5 med bjälklagskanten kompletterad med armering, fig. 11 och 12 visar delar av balkong och bjälklag efter gjutning av bjälklaget, i vy snett uppifrån respektive från sidan.An exemplary embodiment of the device according to the invention will now be described in more detail with reference to the accompanying drawings, in which Fig. 1 shows a part of a prefabricated balcony slab with a bracket at one side edge, Fig. 2 shows a part of a balcony slab with three brackets, Fig. 3 shows a part of a balcony slab with a bracket in side view, Figs. 4-6 correspond to Figs. 1-3, in which reinforcing bars are screwed to the fastening members of the balcony, which reinforcing bars are intended to be anchored in the floor during its casting, Fig. 7 illustrates certain strength conditions in the invention, Figs. 8-10 correspond to Figs. 4-5 with the floor edge supplemented with reinforcement, Figs. 11 and 12 show parts of the balcony and floor layer after casting of the floor layer, in a view obliquely from above and from the side, respectively.
I fig 1-3 illustreras en prefabricerad balkong, levererad från betong- fabriken med stående, väsentligen vertikala, infästningsplåtar 22 ingjutna i balkongplattan 2.Figures 1-3 illustrate a prefabricated balcony, delivered from the concrete factory with upright, substantially vertical, fastening plates 22 cast in the balcony plate 2.
Pâ änden av plåten 22 är en U-profil 8 fastsvetsad.A U-profile 8 is welded to the end of the plate 22.
En likadan U-profil är lämpligen fastsvetsad pâ den i balkongplattan 2 injutna änden av fästplâten 22 för att förbättra dess förankring i balkong- plattan.A similar U-profile is suitably welded to the end of the mounting plate 22 inserted into the balcony plate 2 in order to improve its anchoring in the balcony plate.
De sålunda framställda balkongerna levereras sålunda med fästen, som endast skjuter ut en mindre sträcka från balkongplattan, vilket underlättar transport och annan hantering av de prefabricerade balkongerna.The balconies thus manufactured are thus delivered with brackets, which only project a small distance from the balcony slab, which facilitates transport and other handling of the prefabricated balconies.
Pâ byggarbetsplatsen monteras bal kongpl attan genom att armeringsjärn 10,12 med gängade ändar fastskruvas i U-profilernas 8 liv, efter det att balkongplattan 2 fixerats i rätt läge vid bjälklagskanten. Dessa armerings- järn 10,12 förankras sedan i bjälklaget vid dess gjutning.At the construction site, the bal kongpl attan is mounted by screwing reinforcement iron 10,12 with threaded ends into the life of the U-profiles 8, after the balcony plate 2 has been fixed in the correct position at the floor edge. These rebar 10,12 are then anchored in the floor during its casting.
Hâllfasthetsmässiga fördelar uppnås genom att armeringsjärnen 10,12 fastskruvas i profillivens övre delar, såsom illustreras i fig 4-6. Arme- ringsjärnen 10,12 upptar sålunda dragkrafter och betongen under stängerna tryckkrafter, vilket kraftpar alltså upptar det inspänningsmoment som kommer vid konsolade balkongkonstruktioner.Strength advantages are achieved by screwing the reinforcing bars 10,12 into the upper parts of the profile life, as illustrated in Figs. 4-6. The reinforcing bars 10,12 thus absorb tensile forces and the concrete under the bars compressive forces, which pair of forces thus absorbs the clamping moment that occurs with braced balcony constructions.
Såsom illustreras i fig. 7 får man ett böjmoment M på infästningen i betongen, som skall upptas av dragkraften FS i armeringsjärnen och en tryck- resultant FC från betongen, vilket sker på gynnsammare sätt om dragkraften FS angriper i profillivets övre del. 466 507 En väsentlig faktor att beakta vid dimensioneringen av infästningen är att tryckytan vid betongen blir tillräckligt stor, så att betongen ej krossas till följd av böjmomentet M. Fördelningen av spänningen 0 i betongen illus- treras i-fig. 7.As illustrated in Fig. 7, a bending moment M is obtained on the attachment in the concrete, which is to be absorbed by the tensile force FS in the reinforcement bars and a pressure resultant FC from the concrete, which takes place in a more favorable manner if the tensile force FS attacks in the upper part of the profile life. 466 507 An important factor to consider when dimensioning the attachment is that the pressure surface at the concrete becomes sufficiently large, so that the concrete is not crushed as a result of the bending moment M. The distribution of the stress 0 in the concrete is illustrated in fig. 7.
Montaget på byggarbetsplatsen blir således vid uppfinningen mycket enkelt och består endast i fastskruvning av de gängade armeringsjärnen i U- profilerna.The assembly at the construction site thus becomes very simple in the invention and consists only in screwing the threaded reinforcement bars into the U-profiles.
För att uppnå erforderlig hållfasthet i betongen vid bjälklagskanten krävs normalt att den kompletteras med armering, såsom illustreras i fig. 8- 10. Armeringen utgörs lämpligen av längsgående armeringsstänger 14, omslutna av armeringsbyglar 15, vid varje fästplât. Därefter gjutes bjälklaget, vilket alltså i detta utföringsexempel är platsgjutet.In order to achieve the required strength in the concrete at the floor edge, it is normally required that it be supplemented with reinforcement, as illustrated in Figs. 8-10. The reinforcement preferably consists of longitudinal reinforcing bars 14, enclosed by reinforcing brackets 15, at each fastening plate. Then the floor is cast, which in this exemplary embodiment is spot cast.
Uppfinningen är emellertid användbar även vid andra typer av bjälklag, t ex med kvarsittande form och prefabricerade bjälklag.However, the invention is also applicable to other types of floors, for example with a retained shape and prefabricated floors.
I fig. 11 och 12 visas balkongen monterad vid bjälklaget 4.Figures 11 and 12 show the balcony mounted to the floor 4.
Med fördel anbringas isolering mellan balkongplatta och bjälklag i samband med monteringen. Denna isolering kan utgöra kant för bjälklagets gjutform. Isoleringen är lämpligen av brandsäkert material, såsom stenull.It is advantageous to apply insulation between the balcony slab and the floor in connection with the installation. This insulation can form an edge for the mold of the floor. The insulation is suitably made of fireproof material, such as rock wool.
Härigenom uppfylls brandsäkerhetsnormerna och man får god värmeisolering mellan balkong och bjâlklag.In this way, the fire safety standards are met and you get good thermal insulation between the balcony and the floor.
Fästplâten kan lämpligen ha dimensionerna 270 x 120 x 20 mm. Plâtens dimensioner behöver ej alltid vara bestämd enbart av hâllfasthetsmässiga hänsyn. Ibland kan det finnas anledning att beakta infästningens egenfrek- vens, vilken ändras med fästplâtens tjocklek.The mounting plate can suitably have the dimensions 270 x 120 x 20 mm. The dimensions of the plate do not always have to be determined solely for reasons of strength. Sometimes there may be reason to consider the natural frequency of the fastening, which changes with the thickness of the fastening plate.
Lämplig U-profil kan vara USP-140. Lämpligt avstånd mellan bjälklagens och balkongens mot varandra vända kanter kan vara 70 mm.Suitable U-profile can be USP-140. A suitable distance between the facing edges of the floor and the balcony can be 70 mm.
Ovan har anordningen enligt uppfinningen beskrivits tillämpad på in- fästning av balkong vid betongbjälklag. Anordningen enligt uppfinningen är emellertid självfallet användbar för infästning av andra utskjutande kon- struktioner vid bjälklag, såsom loftgångar, bryggor etc. Den ovan, i anslut- ning till figurerna beskrivna utföringsformen, och i synnerhet ovan angivna siffervärden, utgör självfallet enbart exempel, som kan modifieras inom ramen för det av patentkraven definierade skyddsomfânget.Above, the device according to the invention has been described applied to the attachment of a balcony to concrete floors. However, the device according to the invention is of course useful for attaching other projecting constructions to floors, such as attic corridors, bridges, etc. The embodiment described above, in connection with the figures, and in particular the numerical values given above, is of course only examples, which can modified within the scope of the scope of protection defined by the claims.
