Gevelmetselwerk lateien
• Stalen hoeklijn lateien
• Geveldragers
• Murfor® lateien
• Overspanningen tot 4m
• Min. Hoogte van 50 cm
• Vaak voldoen 2-3 strips Murfor
→ kosten besparingen tot 20%
mogelijk (materiaal , arbeid)
Zie STS22 , hfst Uitvoering §7.4.6.2 Lateien
Gevelmetselwerk lateien : Murfor® latei
Gevelmetselwerk lateien : Murfor® latei
Dilataties
• Metselwerk krimpt
en zet uit
• Indien hiervoor
geen
voorzieningen
getroffen worden
kan het fout gaan
• Dilatatie voegen
Dilataties
• Maximum dilatatie afstanden
volgens STS22 (hfst Uitvoering
§7.11.4)
• Murfor® laat toe deze afstanden
op te drijven (~ +50% of
dilatatie-loos in toekomst?)
• Murfor® rond openingen in
gevel
Dilataties : on-esthetisch geplaatste voegen
Dilataties : Murfor® dilatatie advies
Dilataties : referentie Kolumba Museum – Köln (2002)
Winddragend metselwerk
•

Murfor® gewapende wanden
kunnen hogere laterale lasten
aan (wind, grond/waterdruk,
seismisch)

•

Mogelijkheid tot dunnere
muren, langere
overspanningen

•

Bvb dakopstand muur tussen
kolommen.

•

Design volgens STS22 (hfst
Stabiliteit §3.3.4) en EC6

Laterale draagkracht muur
neemt af met dikte steen

•

Compenseren door meer
spouwankers ?

→Thermisch ongunstig !
(bij 4 #/m² toch - 4% R-waarde
muur)
•
Brick7 , 1m H x 1m L
• Ongewapend : laterale capaciteit 3,7kN/m²
• EFS 40mm alle 4 lagen : 22,2 kN/m²

Compenseren door lintvoeg
wapening !
