W matanda, zvinhu zvakakosha zvimiro muinjiniya nekuvaka, nekuda kwesimba radzo uye kuita zvakasiyana. Muchinyorwa chino, tichaongorora zviyero zvakajairwa, zvinhu zvinoshandiswa, uye makiyi ekusarudza iyo W yakanaka yepurojekiti yako, kusanganisira senge.14x22 W danda, 16x26 W danda, ASTM A992 W danda, nezvimwe.
AW beam isimbi yesimbi ine "W"-yakaita muchinjikwa-section, inoumbwa neshaft (vertical central section) uye maviri flanges (horizontal zvikamu pamativi). Iyi geometry inopa yakanakisa kuramba kukotama uye kuremedza, ichiita kuti ive yakakodzera kune zvivakwa zvinotsigira muzvivakwa, mabhiriji, uye mapurojekiti emaindasitiri. Mazwi W-beam, W-profile, uye W-beam anowanzo shandiswa zvakasiyana kureva rudzi urwu rweprofile.
W-beam zviyero zvinotsanangurwa nehurefu hwavo hwese (kuyerwa kubva kune imwe mugumo weflange kuenda kune imwe) uye huremu pamutsara tsoka, kunyangwe dzimwe nguva vachinzi flange kureba uye upamhi mune shorthand. Mamwe emhando dzakakurumbira dzinosanganisira:
12x16 W Beam: Inenge masendimita gumi nembiri kumusoro, inorema makirogiramu gumi nematanhatu netsoka.
6x12 W Beam: 6 inches kukwira, kurema 12 mapaundi patsoka, yakanakira zvikumbiro zvidiki.
14x22 W Beam: 14 inches yakakwirira, inorema 22 pounds netsoka, inoshandiswa muzvivakwa zvepakati-kati.
16x26 W Beam: Pa 16 inches yakakwirira uye inorema 26 pounds netsoka, inokodzera mitoro inorema.
Iyo inonyanya kushandiswa W-beam simbi inosangana neASTM A992 chiyero, iyo inotsanangura simbi yepamusoro ine simba regoho re50 ksi (50,000 pounds per square inch). Iyi simbi inozivikanwa ne:
Kupokana kwayo nekuora kana ichirapwa nemishonga yekudzivirira.
Iyo ductility, iyo inobvumira inodzorwa deformation pasina kutyora.
Kugona kwayo kumira static uye dynamic mitoro, zvichiita kuti ive yakakodzera kune dzakaoma nharaunda.
Pamusoro peASTM A992 simbi, W-matanda anogonawo kuwanikwa mune mamwe marudzi esimbi, akadai seASTM A36, kunyange zvazvo A992 inosarudzwa mumapurojekiti makuru ekugadzirisa nekuda kwesimba rayo guru.
Tsanangura Zvinodiwa Zveunyanzvi
Inotsigira Mitoro: Verenga iyo static (yega-huremu) uye ine simba (inofamba mitoro) inotakura danda rinotsigira. Mienzaniso yakadai seye 16x26 W-beam inokodzera mitoro inorema, nepo 6x12 W-danda iri nani kune zvidiki zvimiro.
Hurefu hunodiwa: W-matanda anogadzirwa muhurefu hwakakwana, asi anogona kugadzirwa kune yega yega purojekiti. Ita shuwa kuti kureba hakuzokonzerese zvekufambisa kana nyaya dzekuisa.
Verify the Standard and Material
Ita shuwa kuti danda rinosangana neASTM A992 yakajairwa kana iri hombe purojekiti, sezvo izvi zvinovimbisa mayunifomu emuchina.
Ongorora mhando yesimbi: inofanirwa kuratidza mamakisi emugadziri wepamutemo uye zvitupa zvekuteedzera zviyero zvepasirese.
Ongorora Mutengesi
Kuda vagadziri vane ruzivo musimbiW-matandauye mukurumbira pamusika. Bvunza mareferensi uye ongorora mapurojekiti avo apfuura.
Enzanisa mitengo, asi usakanganwa kuti zvinhu zvemhando yakakosha kupfuura mutengo wakaderera. Yakaderera-mhando W-matanda inogona kutungamirira mukukundikana kwemaitiro munguva refu.
Funga nezveSurface Treatment
W-matanda akafumurwa kune zvakatipoteredza anofanirwa kuve ne-anti-corrosion kurapwa, senge epoxy pendi kana galvanization. Izvi zvinowedzera kusimba kwavo, kunyanya munzvimbo dzine hunyoro kana munyu.
Verify Specific Application
Kune mapurojekiti akadai semabhiriji kana zvivakwa zvirefu, kusarudzwa kweW-beam kunofanira kuitwa pamwe chete neinjiniya yezvimiro, uyo anozosarudza zviyero zvakakodzera uye zvinhu zvinoenderana nezviyero zvemunharaunda uye zvinotakura zvinodiwa.
Matanda eW-matanda akakosha mukuvaka kwemazuva ano, uye kusarudzwa kwawo chaiko kunoenderana nekunzwisisa hukuru hwayo (senge 14x22 W-beam kana 12x16 W-beam), zvinhu (kunyanya ASTM A992 simbi), uye zvinodiwa neprojekiti. Paunenge uchitenga, isa pamberi pemhando, kutevedzera zviyero, uye nemukurumbira wemutengesi, nokudaro uchive nechokwadi chekuchengetedza uye kusimba kwechimiro chako.
