Mzere wa Himagwiritsidwa ntchito kwambiri popanga chitsulo masiku ano. Pamwamba pa chitsulo cha gawo la H palibe kupendekera, ndipo pamwamba ndi pansi pali malo ofanana. Chizindikiro cha gawo la H - beam ndi chabwino kuposa chachikhalidwe.I - kuwala, chitsulo cha njira ndi chitsulo cha Angle. Ndiye kodi kuwala kwa H beam ndi kotani?
1. Mphamvu yayikulu yomanga
Poyerekeza ndi I-beam, gawo la modulus ndi lalikulu, ndipo mkhalidwe wonyamula ndi womwewo nthawi yomweyo, chitsulocho chikhoza kupulumutsidwa ndi 10-15%.
2. Kalembedwe kosinthasintha komanso kolemera
Ngati mtengo wake ndi wofanana, kapangidwe ka chitsulo kamakhala kokulirapo ndi 50% kuposa kapangidwe ka konkriti, zomwe zimapangitsa kuti kapangidwe kake kakhale kosinthasintha.
3. Kulemera kochepa kwa kapangidwe
Poyerekeza ndi kapangidwe ka konkriti, kulemera kwa kapangidwe kake ndi kopepuka, kuchepetsa kulemera kwa kapangidwe kake, kuchepetsa mphamvu yamkati ya kapangidwe kake, kungapangitse kuti zofunikira pakukonza maziko a kapangidwe kake zikhale zochepa, kapangidwe kake ndi kosavuta, ndipo mtengo wake umachepetsedwa.
4. Kukhazikika kwakukulu kwa kapangidwe kake
Mzere wozungulira wa H ndiye kapangidwe ka chitsulo chachikulu, kapangidwe kake ndi kasayansi komanso koyenera, kabwino komanso kosinthasintha, kokhazikika kwambiri, koyenera kugwedezeka ndi kugwedezeka kwa nyumba zazikulu, kuthekera kolimba kolimbana ndi masoka achilengedwe, makamaka koyenera nyumba zina m'malo okhudzidwa ndi zivomerezi. Malinga ndi ziwerengero, padziko lonse lapansi lomwe lili ndi chivomerezi champhamvu kwambiri cha 7 kapena kuposerapo, nyumba zokhala ndi chitsulo chooneka ngati H makamaka chitsulo sizinachite bwino.
5. Wonjezerani malo ogwiritsira ntchito bwino a kapangidwe kake
Poyerekeza ndi kapangidwe ka konkriti, gawo la gawo la chitsulo ndi laling'ono, lomwe lingathe kuwonjezera malo ogwiritsira ntchito bwino a nyumbayo, kutengera mitundu yosiyanasiyana ya nyumbayo, lingathe kuwonjezera malo ogwiritsira ntchito bwino a 4-6%.
6. Sungani ntchito ndi zipangizo
Poyerekeza ndi chitsulo chowotcherera cha H-beam, chimatha kupulumutsa kwambiri ntchito ndi zipangizo, kuchepetsa kugwiritsa ntchito zipangizo zopangira, mphamvu ndi ntchito, kupsinjika kochepa, mawonekedwe abwino komanso khalidwe la pamwamba.
7. Kukonza kosavuta kwa makina
Zosavuta kulumikiza ndi kuyika momwe zimakhalira, komanso zosavuta kuchotsa ndikugwiritsanso ntchito.
8. Kuteteza Zachilengedwe
Kugwiritsa ntchitoChitsulo cha gawo la Hakhoza kuteteza bwino chilengedwe, zomwe zimawonekera m'mbali zitatu: choyamba, poyerekeza ndi konkriti, ingagwiritse ntchito zomangamanga zouma, zomwe zimapangitsa kuti phokoso likhale lochepa komanso fumbi lichepe; Chachiwiri, chifukwa cha kuchepetsa kulemera, kuchotsa nthaka pang'ono pomanga maziko, kuwonongeka pang'ono kwa zinthu zapadziko lapansi, kuwonjezera pa kuchepetsa kwakukulu kwa konkriti, kuchepetsa kuchuluka kwa kukumba miyala, komwe kumathandiza kuteteza chilengedwe; Chachitatu, moyo wa ntchito ya nyumbayo utatha, kuchuluka kwa zinyalala zolimba zomwe zimapangidwa pambuyo poti nyumbayo yagwetsedwa kumakhala kochepa, ndipo mtengo wobwezeretsanso wa zitsulo zotsalira ndi wokwera.
9. Kuchuluka kwa mafakitale opanga zinthu
Kapangidwe kachitsulo kozikidwa pa mtanda wa H wotentha kamakhala ndi kupanga kwakukulu kwa mafakitale, komwe ndikosavuta kupanga makina, kupanga kwambiri, kulondola kwambiri, kuyika kosavuta, kutsimikizira khalidwe mosavuta, ndipo kumatha kumangidwa kukhala fakitale yopanga nyumba yeniyeni, fakitale yopanga milatho, fakitale yopanga mafakitale, ndi zina zotero. Kukula kwa kapangidwe kachitsulo kwapanga ndikuyendetsa chitukuko cha mafakitale atsopano mazana ambiri.
10. Liwiro la ntchito yomanga ndi lachangu
Malo ochepa, komanso oyenera kumangidwa nthawi zonse, sakhudzidwa kwambiri ndi nyengo. Liwiro la kapangidwe ka chitsulo chopangidwa ndi chitsulo chotenthedwa ndi H beam ndi pafupifupi nthawi ziwiri kapena zitatu kuposa kapangidwe ka konkriti, chiwongola dzanja cha ndalama chimawirikiza kawiri, ndalama zimachepetsedwa, kuti tisunge ndalama. Potengera "Nsanja ya Jinmao" ku Pudong ku Shanghai, "nyumba yayitali kwambiri" ku China mwachitsanzo, thupi lalikulu la nyumbayo lomwe lili ndi kutalika kwa pafupifupi 400m linamalizidwa pasanathe theka la chaka, pomwe kapangidwe ka chitsulo ndi konkriti kanafunika zaka ziwiri kuti amalize nthawi yomanga.
