Spre deosebire de cuiele standard de 70-100 mm folosite la astereal\u0103 sau cofraje, cuiele lungi sunt veritabile „ancore” din o\u021bel. La Ancora SCM, producem aceste elemente cu diametre masive, menite s\u0103 str\u0103pung\u0103 \u0219i s\u0103 lege grinzi de sec\u021biuni mari.<\/em><\/p>\n<\/div>\n<\/div>\n<\/div>\n

Cel mai mare risc la utilizarea unui cui cu diametrul de 8.0 mm este despicarea fibrei lemnoase, fenomen care anuleaz\u0103 complet rezisten\u021ba \u00eembin\u0103rii.<\/em><\/p>\n<\/div>\n<\/div>\n<\/div>\n

\u2022 <\/span>Regula pre-g\u0103uririi<\/strong>: Pentru cuiele cu diametru mai mare de 6 mm, inginerii structuri\u0219ti recomand\u0103 forarea prealabil\u0103 a unei g\u0103uri de ghidaj (pre-g\u0103urire). Burghiu trebuie s\u0103 aib\u0103 un diametru egal cu 0.8 x diametrul cuiului (ex: pentru un cui de 8.0 mm, folosi\u021bi un burghiu de 6.0 – 6.5 mm).<\/span><\/p>\n
