Cofrajul pentru diafragme

Domenii de utilizare Caracteristici / Avantaje Lista de produse
 

Mic & compact

EcoAs este un sistem de cofrare ramă, care poate fi montat manual, este multifuncţional, compact, fiind destinat utilizării la:

  • fundaţii
  • curţi de lumină
  • grinzi şi grinzi întoarse
  • centuri
  • rampe scări
  • ziduri de sprijin grădină

  1. betonare la înălţimea elementului, posibilă independent de reţeta de preparare a betonului, consistenţa betonului, condiţiile meteorologice si fără a se lua în considerare viteza de betonare
 

Rama

CARACTERISTICI

AVANTAJE

  • ramă din profile închise, foarte durabile, din oţel
  1. rigiditate sporită la torsiune, durată de viaţă sporită 
  • Profilele de ramă MEVA sunt prevăzute cu două straturi. Baza o constituie o grunduire neagră anticorozivă. O protecţie suplimentară împotriva coroziunii este asigurată prin conservarea spaţiului gol al ramei cu ceară. Stratul roşu dintr-un praf sintetic special este aplicat printr-o procedură de vopsire în câmp electrostatic, crescând astfel rezistenţa la zgârieturi şi lovituri a ramei.
  1. protecţie sporită anticorozivă
  2. necesitate redusă de curăţare, datorită aderenţei scăzute a betonului
  3. durată de viaţă sporită

  1. cei mai buni timpi de cofrare la realizarea fundaţiilor
  2. poziţia găurilor pentru tiranţi avantajoasă în cazul rosturilor de betonare cu benzi de etanşare
  • un tensor la nivelul punctului de îmbinare al elementelor, la utilizarea pentru fundaţii
  1. nu mai este nevoie de poziţia superioară a găurilor de ancoraj
  • îmbinarea elementelor cu cleştele MEVA - o singură piesă, numai 1,5 kg
