Opanga CFS Apambana Mphotho Yaumisiri pa Ntchito Yovuta ku Arizona

Digital Building Components (DBC), wopanga zitsulo zozizira (CFS) za polojekiti ya Mayo West Tower ku Phoenix, Arizona, adalandira Mphotho ya 2023 Cold Formed Steel Engineers Institute (CFSEI) chifukwa cha Kupambana mu Design (Municipal Services/ Services ”) . chifukwa chakuthandizira kwake pakukulitsa gawo la chipatalacho. Njira zatsopano zopangira ma facade.
Mayosita ndi nyumba yansanjika zisanu ndi ziwiri yomwe ili ndi masikweya mita pafupifupi 13,006 (140,000 sq ft) ya khoma lakunja la CFS lopangidwa kale lopangidwa kuti likulitse pulogalamu yachipatala ndikuwonjezera mphamvu zachipatala chomwe chilipo. Mapangidwe a nyumbayi amakhala ndi konkriti pa sitima yachitsulo, zitsulo zopangira zitsulo ndi ma panels akunja a CFS osanyamula katundu.
Pa ntchitoyi, Pangolin Structural anagwira ntchito ndi DBC ngati injiniya wa CFS. DBC inapanga makoma pafupifupi 1,500 okhala ndi mawindo oyikiratu, pafupifupi 7.3 m (24 ft) utali ndi 4.6 m (15 ft) utali.
Chinthu chimodzi chodziwika bwino cha Mayota ndi kukula kwa mapanelo. 610 mm (24 mu.) makulidwe a khoma la 152 mm (6 mu.) Kunja kwa Insulation ndi Finishing System (EIFS) yoikidwa pa 152 mm (6 mu.) matabwa a J-high 305 mm (12 in.) pamwamba pa ndime yokhala ndi zomangira . . Kumayambiriro kwa ntchitoyi, gulu lopanga DBC linkafuna kufufuza njira zosiyanasiyana zopangira khoma lazenera la 610 mm (24 in) wandiweyani, 7.3 m (24 ft) lalitali lokhazikitsidwa kale zenera. Gululo lidaganiza zogwiritsa ntchito 305 mm (ma mainchesi 12) pagawo loyamba la khoma, kenako ndikuyika matabwa a J mopingasa pansanjikayo kuti athandizire kunyamula ndikukweza mapanelo aatali awa.
Pofuna kuthetsa vuto lochoka pakhoma la 610 mm (24 in.) kupita ku khoma loyimitsidwa la 152 mm (6 in.), DBC ndi Pangolin anapanga mapanelo ngati zigawo zosiyana ndikuwalumikiza pamodzi kuti azikweza ngati unit.
Kuonjezera apo, mapanelo amkati mwa mawindo a mawindo adasinthidwa ndi 610 mm (24 mu) makoma akuluakulu a 102 mm (4 mu) makoma akuluakulu. Kuti athane ndi vutoli, DBC ndi Pangolin adakulitsa kulumikizana mkati mwa 305 mm (12 in) stud ndikuwonjezera 64 mm (2.5 in) stud ngati chodzaza kuti zitsimikizire kusintha kosalala. Njirayi imapulumutsa mtengo wamakasitomala pochepetsa kukula kwa ma studs mpaka 64 mm (2.5 in.).
Chinthu chinanso chapadera cha Mayosita ndi sill yotsetsereka, yomwe imatheka powonjezera mbale yokhotakhota ya 64 mm (2.5 in.) yokhala ndi zipilala ku njanji yachikhalidwe ya 305 mm (12 in.).
Ena mwa makoma a pulojekitiyi amapangidwa mwapadera ndi "L" ndi "Z" pamakona. Mwachitsanzo, khoma ndi 9.1 m (30 ft) utali koma 1.8 m (6 ft) m'lifupi, ndi "L" ngodya zooneka 0.9 m (3 ft) kuchokera gulu lalikulu. Kuti alimbikitse kulumikizana pakati pa mapanelo akulu ndi ang'onoang'ono, DBC ndi Pangolin amagwiritsa ntchito zikhomo ndi zingwe za CFS ngati X-brace. Mapanelo ooneka ngati L amenewa amafunikiranso kulumikizidwa ku batten yopapatiza yokhala ndi 305 mm (12 in) m'lifupi, yotalikira 2.1 m (7 ft) kuchokera panyumba yayikulu. Yankho lake linali kuyika mapanelo awa m'magulu awiri kuti achepetse kuyika.
Kupanga kampandako kunabweretsa vuto lina lapadera. Pofuna kuti chipatalacho chiwonjezeke molunjika m'tsogolo, zolumikizira zidapangidwa m'makoma akulu ndikumangirira pansi kuti zitheke kupasuka.
Womanga wolembetsedwa wa polojekitiyi ndi HKS, Inc. ndipo injiniya wolembetsedwa ndi PK Associates.
