Nkhani - Maupangiri Athunthu a W Beams: Makulidwe, Zida, ndi Kuganizira Zogula

W masamba, ndi zinthu zofunika kwambiri pa zomangamanga ndi zomangamanga, chifukwa cha mphamvu zake komanso kusinthasintha. M'nkhaniyi, tiwona miyeso yofananira, zida zomwe zimagwiritsidwa ntchito, ndi makiyi osankha mtengo woyenerera wa W pulojekiti yanu, kuphatikiza monga14x22W mtengo, 16x26W mtengo, Mtengo wa ASTM A992 W, ndi zina.

Kulowera Kwakuya mu H-Beams Kuyang'ana pa ASTM A992

Kodi W beam ndi chiyani?

AW mtengo ndi mbiri yachitsulo yokhala ndi "W"-woboola pakati, yopangidwa ndi shaft (yolunjika pakati) ndi ma flanges awiri (magawo opingasa m'mbali). Geometry iyi imapereka kukana kopindika ndi kulemetsa, kuwapangitsa kukhala abwino pazothandizira zomanga m'nyumba, milatho, ndi ma projekiti a mafakitale. Mawu akuti W-beam, W-profile, ndi W-beam nthawi zambiri amagwiritsidwa ntchito mosiyana kutanthauza mbiri yamtunduwu.

Common W-Beam Dimensions

Miyezo ya W-beam imatanthauzidwa ndi kutalika kwake konse (kuyezedwa kuchokera kumapeto kwa flange kupita ku imzake) ndi kulemera kwa phazi lozungulira, ngakhale nthawi zina amatchedwa kutalika kwa flange ndi m'lifupi mwachidule. Ena mwa miyeso yodziwika kwambiri ndi awa:
12x16W mtengo: Pafupifupi mainchesi 12 m'mwamba, wolemera mapaundi 16 pa phazi.
6x12W mphamvu: mainchesi 6 m'mwamba, yolemera mapaundi 12 pa phazi, yabwino kwa mapulogalamu ang'onoang'ono.
14x22W mtengo: mainchesi 14 m'mwamba, yolemera mapaundi 22 pa phazi, yogwiritsidwa ntchito m'mapangidwe apakati.
16x26W mtengo: Pa mainchesi 16 m'mwamba ndi kulemera mapaundi 26 pa phazi, ndi yoyenera kunyamula katundu wolemera.

Chitsulo cha W-beam chomwe chimagwiritsidwa ntchito kwambiri chimakumana ndi muyezo wa ASTM A992, womwe umatanthawuza chitsulo chogwira ntchito kwambiri chokhala ndi mphamvu zokolola za 50 ksi (mapaundi 50,000 pa inchi imodzi). Chitsulo ichi chimadziwika ndi:
Kukaniza kwake ku dzimbiri pothandizidwa ndi mankhwala oteteza.
ductility ake, amene amalola ankalamulira deformations popanda kuswa.
Kukhoza kwake kupirira katundu wosasunthika komanso wosunthika, ndikupangitsa kuti ikhale yabwino kumadera ovuta.
Kuphatikiza paASTM A992 chitsulo, matabwa a W angapezekenso mumitundu ina yazitsulo, monga ASTM A36, ngakhale A992 imakonda ntchito zazikulu zamapangidwe chifukwa cha mphamvu zake zazikulu.

Mfundo Zofunika Kwambiri Pogula W-Beams

Kutanthauzira Zofunikira Zaukadaulo
Katundu Wothandizira: Mawerengereni osasunthika (kulemera kwanu) ndi zosunthika (zonyamula katundu) zomwe mtengowo ungathandizire. Zitsanzo monga 16x26 W-mtengo ndizoyenera kunyamula katundu wolemera, pamene 6x12 W-mtengo ndi yabwino kwa nyumba zazing'ono.
Utali Wofunika: Mitanda ya W imapangidwa muutali wokhazikika, koma imatha kusinthidwa pulojekiti iliyonse. Onetsetsani kuti kutalika sikudzayambitsa zovuta zamayendedwe kapena kukhazikitsa.

Tsimikizirani Standard ndi Material
Onetsetsani kuti mtengowo ukukumana ndi muyezo wa ASTM A992 ngati ndi polojekiti yayikulu, chifukwa izi zimatsimikizira mawonekedwe amamakina ofanana.
Yang'anani mtundu wachitsulo: iyenera kuwonetsa zolembera zovomerezeka ndi ziphaso zotsatizana ndi miyezo yapadziko lonse lapansi.

Unikani Wopereka
Kukonda opanga odziwa zitsuloZithunzi za Wndi mbiri pamsika. Onani maumboni ndikuwunikanso ma projekiti awo akale.

Fananizani mitengo, koma musaiwale kuti zinthu zakuthupi ndizofunikira kwambiri kuposa mtengo wotsika. Ma W-otsika otsika amatha kuyambitsa kulephera kwadongosolo pakapita nthawi.

Ganizirani za Surface Treatment
Mitanda ya W yomwe imawonekera ku chilengedwe iyenera kukhala ndi mankhwala oletsa dzimbiri, monga utoto wa epoxy kapena galvanization. Izi zimawonjezera kukhazikika kwawo, makamaka m'malo okhala ndi chinyezi kapena mchere.

Tsimikizirani Kugwiritsa Ntchito Mwachindunji
Kwa ma projekiti monga milatho kapena nyumba zazitali, kusankhidwa kwa mtengo wa W kuyenera kupangidwa molumikizana ndi mainjiniya omanga, omwe adzazindikira miyeso yoyenera ndi zida zotengera miyeso yam'deralo ndi zofunikira za katundu.

Mitanda ya W ndi zinthu zofunika kwambiri pakumanga kwamakono, ndipo kusankha kwawo kolondola kumadalira kumvetsetsa makulidwe awo (monga 14x22 W-beam kapena 12x16 W-beam), zinthu (makamaka ASTM A992 chitsulo), ndi zofunikira za polojekitiyi. Mukamagula, yang'anani ubwino, kutsata miyezo, ndi mbiri ya wogulitsa, motero onetsetsani kuti chitetezo ndi kulimba kwa kapangidwe kanu.
