Grede I-If / Beams I-If

Opis elementa

Grede I i If (I filante) su horiyontalni noseći elementi od prednapregnutog betona, konstantne visine, na koje se oslanjanjaju sekundarni elementi krova (npr. korube ili rožnjače), krovni kosači tipa ‘’Opera’’, a koriste se i za horizontalne grede kranskih staza. Odvođenje atmosferske vode se rešava odvdom kroz poseban otvor koji se formira spajanjem dve susedne grede. Oslanjanje krajeva grede I i If vrši se preko neoprenskih ležišta. Spoj grede i stuba se vrši uz pomoć armaturnih šipki koje su pričvršćene u stubu i prilikom montaže provlače se kroz otvore koji se nalaze na krajevima greda I i If. Otvori se potom zalivaju cementnim malterom.

Description of elements

Beams I and If (I filaments) are horizontal supporting elemnts of prestressed concrete, they have constant height and secondary roof elemnets rely on them (e.g. TT slabs or purlins). On them can also rely roof rails named ’Opera’, as well the horizontal crane rails. Drainage of storm water drain is solved through a special opening that is formed by connecting two near beams. Reliance of the beam endings is done through the neoprene bearing. Connection between beasm endings is done through the neoprene bearing.Connection between beams and pillars is done through reinforcing bars which are attached to the pillars, and are pulled trough the openings at the ends of the beams during montage. The openings then meet with Cement mortar.

Grede tipa I

Standardne širine B=50-60cm visine H=80-120cm, karakteiše pravougaoni (puni) poprečni presekna mestu oslonca. Grede širine B=60-70cm visine H=150cm su ’’I’’ poprečnog preseka na mestu oslonca.

Beams typo I

The standard width of B=50-60cm and height of H=80-120cm. These types are characterized by rectangular (full) cross-section at the point of support. The beams width of B=60-70cm and height of H=150cm are characterized by ‘I’ cross-section at the point of support.

Grede tipa If

Standarden širine B=50-60cm i visine H=80-90-90cm su konstantnog poprečnog preseka.

Beams typo If

The standard width of B=50-60cm and height of H=80-90-100cm characterized by the constant cross-section.
