Grede L - TBeams L - T
Grede L i T preseka napravljene su od prednapregnutog betona.
Koriste se kao noseći horizontalni elementi međusprtnih
konstrukcija i krovnih konstrukcija. Stub na koji se oslanjaju L i
T grede treba da ima odgovarajuću širinu poprečnog preseka, zavisno
od osnove grede.
Ukoliko to nije zadovoljeno, stub se proširuje kratkim
elementom. Elementi međuspratne konstrukcije postavljaju se na zub
donjeg dela grede. Grede tipa L i T se oslanjaju preko neoprenskih
ležišta.
Uniform cross-section L- and T- beams are made of pre-stressed
concrete. They are used as supporting horizontal elements for floor
and roof structures.
Columns that support L- and T-beams should have a suitable
crosssectional width, depending on the beam base. If this criterion
is not met, consoles are used to expand the columns. The floor
structure elements are placed on the lower protuberanceof the beam.
The L-and T-beams are supported by consoles on neoprene pads.
