Makoma a zitsulo zotchinga

Mapangidwe amakono a khoma lotchinga nthawi zambiri amafunikira zida zomangika zolimba momwe zimasunthika kuti zigwirizane ndi masiku ano zomwe zikuchulukirachulukira zaulere, ma angles ovuta, komanso kukongola kovala magalasi. Zitsulo zotchinga khoma mafelemu angaonedwe ngati njira yabwino pomanga khoma lotchinga lero. Kwa nthawi yaitali, mbiri yachitsulo monga ntchito yomangamanga yamakono imapindula bwino. Kuyambira pa milatho yokwera mpaka ku ma skyscrapers, imatha kupirira zinthu zina zofunika kwambiri zamapangidwe popanda kupunduka, kugawanika, ngakhale kusweka pakapita nthawi. Ngakhale kuti ntchito yake ndi yapadera, zolepheretsa kupanga zalepheretsa kugwiritsidwa ntchito kwake ngati chinthu choyambirira pamapangidwe a khoma lonyezimira. Komabe, m'zaka zaposachedwa, njira zopangira zotsogola zathana ndi vutoli. Ena opanga nsalu zotchinga apanga zigawo zonse mpaka pomwe dongosolo lathunthu limapezeka nthawi zambiri, kuphatikiza: 1) tsatanetsatane wa kulumikizana ndi zida; 2) gasketing; 3) mbale zokakamiza zakunja ndi zipewa zophimba; ndi 4) khomo lothandizira ndi machitidwe olowera, komanso kufotokozera. Kuphatikiza apo, dongosolo lathunthu la khoma lotchinga lingakhale lothandiza kufewetsa ndi kulinganiza njira zopangira ndi kuyika, ndikukwaniritsa zofunikira pamapangidwe amakono a makatani - mosasamala kanthu za zomwe zasankhidwa. Mwachitsanzo, kukana kwamadzi kumatha kukhala kokulirapo ndi 25 peresenti pakhoma lachitsulo chopanda shelefu kuposa makina wamba opangidwa ndi aluminiyamu wamba. Komanso, kulowa kwa mpweya kumakhala pafupifupi kulibe m'makoma a zitsulo zotchinga. Ngati mwasankha kusankha zitsulo zotchinga khoma muzomangamanga, pali malingaliro angapo ogwiritsira ntchito zitsulo ku mphamvu yake yonse mu ntchito zovuta zotchinga khoma. Kunena mwatchutchutchu, chitsulo ndi champhamvu ndipo chili ndi mphamvu yonyamula katundu wambiri ndi Young's modulus pafupifupi 207 miliyoni kPa (30 miliyoni psi), poyerekeza ndi aluminiyamu, pafupifupi 69 miliyoni kPa (10 miliyoni psi). Izi zimathandiza akatswiri okonza mapulani kuti afotokoze kachitidwe kachitsulo kansalu kansalu kokhala ndi zipatala zazikulu zaulere (zikhale kutalika kowongoka ndi/kapena m'lifupi mwake) ndi makulidwe ocheperako kuposa makoma a aluminium ochiritsira omwe ali ndi miyeso yofananira ndi katundu wogwiritsidwa ntchito. Kuphatikiza apo, mbiri yachitsulo nthawi zambiri imakhala magawo awiri pa atatu a kukula kwa aluminiyamu yofananira pomwe ikukumana ndi njira yofananira yotchinga khoma. Mphamvu yachitsulo imalola kuti igwiritsidwe ntchito m'magulu osakhala akona amakona anayi, pomwe utali wa membala wa chimango ukhoza kukhala wautali kuposa momwe umafunikire pama gridi amtundu wamba, opingasa / opingasa. M'zaka zaposachedwa, chifukwa cha njira zapamwamba zopangira zitsulo, zimatha kumangiriza zitsulo zamitundu yosiyanasiyana, kuphatikiza ma hollow-, I-, T-, U-, kapena L-channel, ndi mamiliyoni ambiri. Ndi mtengo wokwanira wotchinga khoma, zingakhale zodabwitsa kwa inu kukhala ndi makoma osiyanasiyana azitsulo azitsulo omwe amapezeka pa ntchito yanu yomanga.
