Opis elementa

Martini Gradnja u svom proizvodnom programu poseduje međuspratnu konstrukciju tipa IFLED od prednapregnutog betona. Kao i kod drugih prefabrikovanih međuspratnih konstrukcija za montažu istih nophodno je izvršiti monolitizaciju. IFLED međuspre konstrukcije karakterišu postizanje velikih raspona uz velike nosivosti elemenata. Obzirom da se kablovi za prednaprezanje nalaze u jasno definisanim pojasevima, ova međuspratna konstrukcija je pogodna za instalacione otvore. Velika primena ovih elemenata je kod višespratnih garaža i tržnih centara gde se koriste rasponi 8x16m što donosi značajnu racionalizaciju u broju elemenata i omogućava bržu montažu. Takođe, koristi se za ravne krovove. Na otvor sa gornje strane montiranog IFLED-a, postavljaju se profilisani limovi, nakon čega se vrši monolitizacija. Za standardnu širinu 250cm, predviđena su četiti visine elementa: H=30cm, H=40cm, H=50cm i H=60cm. Elementi IFLED po zahtevu ima otpornost na požar do R120’ (norm. UNI 9502).

Description of elements

Martini Gradnja in its manufacturing subsidiary have plate floor type of IFLED of prestressed concrete. As with other prefabricated plate floors, for montage of them it is necessary to do monolithically. IFLED plate floor is characterized by large span ability and elemnts of great carrying capacity. Since the prestressing tendons are in well-defined bands, the plate floors are suitabel for placing installation holes (duct). Best use of these elements in in multi-storage, garages and shopping centers where the spans of 8x16m are often used, because the usage of this construction brings significant rationalization in the number of elements used, while it allows faster montage. Also, they are used for flat roof. At the opening on the upper surface of formed IFLED, profiled sheets are placed, after which follows the procedure of monolithically sheets are placed, after which follows the procedure of monolithically. For a standard width of 250cm, there can be four element heights H=30cm, H=40cm, H=50cm i H=60cm. At the instance of, IFLED element has a fire resistance up to 120 R’ (norm. UNI 9502).

Montaža

Oslanjanje konstrukcije se postiže preko neoprenskih ležišta. Dužina oslanjanjane treba da bude manjaod 18cm. Kod izvođenja stabilizijuće ploče, gornju površinu treba zaliti betonom klase ne manje 30N/mm2, granulometrijskog sastava 0-12. Minimalan sloj za monolitizaciju je 5cm.

Montage

Supporting of structures is achieved by neoprene bearings. Length of suppoting structures should not be less than 18cm. In realization of a stabiliying plate,the upper surface are grouted with concrete of class not les than 30N/mm2, granulometric composition of 0-12. Minimum bed of monolythisation is 5cm.
