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.
