Ukuqulunqwa kwentsimbi epholileyo yinto ehlala ixesha elide, ethembekileyo kunye neendleko ezifanelekileyo kwiiprojekthi zokwakha ezisezantsi kunye neziphakathi.Ngokuqhelekileyo ibhekisa kulwakhiwo lwesakhelo sokukhanya apho izakhi zesakhiwo ezithe nkqo nezithe tye zenziwe ikakhulu yinkqubo yamalungu aphinda-phindayo okusakhelo.Amalungu aqulunqiweyo aqhele ukuhlukaniswa kwi-16 okanye i-intshi ezingama-24 embindini, kunye nokwahluka kwezithuba ezisezantsi nangaphezulu ngokuxhomekeke kwimithwalo kunye nezigqubuthelo.
Amalungu odonga adla ngokuba ngamalungu etshaneli emile nkqo emilebe ethe nkqo, angena kumacandelo etshaneli angafakwanga amagama phezulu nasezantsi.Ulungelelwaniso olufanayo lusetyenziselwa zombini iindibano zomgangatho kunye ne-rafter, kodwa kwisicelo esithe tye kwimigangatho, kunye nesicelo esithe tye okanye esithambekileyo sokwenza ifreyimu yophahla.Izinto ezongezelelweyo zenkqubo yokuqulunqa ziquka i-fasteners kunye nezixhumi, i-braces kunye ne-bracing, iziqeshana kunye nezixhumi.Umgangatho obandayo owenziwe ngentsimbi kunye neetrasi zophahla nazo ziyafumaneka kwizicelo zokuqulunqa iintsimbi ezibandayo.
Intsimbi epholileyo epholileyo ibhekisela kwinkqubo yokuvelisa apho i-metallic-coated sheet sheet yenziwe i-roll-formed ibe yimveliso efana ne-studs, joists, track, headers, engile, amalungu e-truss kunye namanye amacandelo.Kwifreyim yentsimbi epholileyo, ubukhulu bezinto eziqhelekileyo buvela kwi-0.0147 in. (0.373 mm) ukuya malunga ne-1/8 in. (3.175 mm).Iimveliso zetsimbi eziqhelekileyo ezibandayo zichazwe kwi-AISI S220, i-North American Standard ye-Cold-Formed Steel Nonstructural Framing, i-2020 Edition kunye ne-AISI S240, i-North American Standard ye-Cold-Formed Steel Structural Framing, i-2020 Edition (ukukhutshelwa kwamahhala kwi-www.aisistandards. org).Iintlobo ngeentlobo zeemveliso zentsimbi ezenziwe ngokubanda ziyafumaneka kubavelisi abahlukeneyo.Iimveliso zentsimbi ezibandayo ezenziwe ngentsimbi ziqhele ukwenziwa ngentsimbi egqunywe ngentsimbi epholileyo enezinki enamandla okuvelisa ama-33 ksi okanye ama-50 ksi.
Ukwakhiwa kwentsimbi epholileyo kuMntla Melika kuyilwe kwaye kwakhiwe ngokuhambelana nemigangatho ephuhliswe yi-American Iron and Steel Institute.Ukuqulunqwa kwentsimbi epholileyo iboleka kwizakhiwo zezakhiwo apho umgangatho kunye neenkqubo zophahla zixhaswa kwiindonga ezithwele.Ukuqulunqwa kwentsimbi epholileyo kusetyenziswe ngempumelelo kwiiprojekthi zokwakha ezingaphezu kwamabali angama-10 ubude.
