Amafasitela amahle e-aluminium extrusions abalulekile endlini yethu. Khetha iphrofayela yewindi ye-aluminium evumelekile, gwema ukusebenzisa izinto ezinephutha ezingase zithinte ukuqina ngemva kokufakwa.
Ngenkathi kushintsha amafasitela neminyango esetshenziswe ekhaya, abantu abajwayele ukufakwa nokuqaqa. Uma kunjalo, ikhwalithi yokufaka iba yisihloko sokufunda ukuze wonke umsebenzisi asiqonde.
Ngesikhathi nangemva kokufakwa, ngaphandle kokuqapha izinga eliphezulu, kudinga ukunaka izinqubo zokufakwa kwabasebenzi, ukukhetha okusebenzayo.iphrofayili yewindi le-aluminium, gwema ukusebenzisa izinto ezinephutha ezingase zithinte ukuqina ngemva kokufakwa.
Ngenkathi ikhipha,ama-extrusions ewindi le-aluminium futhi iminyango idinga uzimele, uxhumo oluzinzile, ukubekwa uphawu, nokuhlolwa kokugcina, zonke lezi zinqubo ezifanele zihlobene nekhwalithi yefasitela neminyango nokuqina.
Uma sikhuluma ngokufaka, ukwenza uhlaka kuyisiteji esibalulekile, futhi sinquma ukubuka kwewindi nokusebenza. Setha izixhumanisi zamafreyimu zibe yisisekelo sezimbobo ezisefasiteleni nasezicabheni. Bese, faka ifremu khona kanye ngaphakathi kwezixhumanisi ezisethiwe.
Ukufakwa okomile kanye nokufakwa okumanzi
Izindlela zokufaka amafasitela nezicabha zesistimu zihlukaniswe izinhlobo ezimbili, i-Dry-installation kanye ne-Wet-installation. Ngenxa yomehluko wezindlela zokufaka, izindlela zokufaka amafreyimu lapho odongeni nazo zihlukile.
1. Ukufaka okomile
Ukufakwa okomile, amafreyimu ensimbi kufanele afakwe ngaphambi kokudweba odongeni,aluminium ifreyimu extrusion iwindi kufanele kwenziwe ngemuva kokudweba odongeni. Bheka ngezansi ngezidingo zokufakwa kwamafreyimu ensimbi:
(1) Ububanzi obuvumelekile bohlaka lwensimbi nohlaka oluseceleni lwewindi kufanele lube banzi kuno-30mm.
(2) Ukukhetha izinsimbi zozimele zensimbi ukuxhuma izimbobo ngezindonga. Ukuxhuma udonga namafreyimu ensimbi angaphandle ngezixhumi.
(3) Igebe lezixhumi zensimbi nama-engeli kufanele libe ngaphansi kuka-150mm, izibophelelo ezimbili kufanele zigcine igebe elingaphansi kuka-500mm.
2. Ukufakwa okumanzi
Ngenkathi usebenzisa ukufakwa okumanzi, amafasitela esistimu namafreyimu eminyango kufanele afakwe ngaphambi kokupenda odongeni. Amafreyimu wefasitela nezicabha kufanele asebenzise izinsimbi ukulungisa. Izicelo ziyefana nokufaka okomile. Igebe lamafreyimu eminyango yamafasitela esistimu kanye nezinto zokubopha akufanele libe ngaphezu kuka-150mm, igebe phakathi kwezibophelelo ezimbili kufanele libe ngaphansi kuka-500mm.
Mayelana nendlela yokuxhuma yezinsimbi kanye nezikhala zeminyango yamafasitela, ingakhetha isikulufu sokuzithepha ngokwakho noma i-POP Self Plugging Rivet. Ngemuva kokufakwa, izindonga ezizungeze amafasitela kufanele zibe nokwelashwa okulondolozayo usebenzisa amapende okulondoloza noma amafilimu epulasitiki.
