Yintoni inkqubo yemveliso yentsimbi H umqadi?

Imiqadi yentsimbi H, eyaziwa ngokuba yintsimbi emile okwe-H, iyinxalenye ebalulekileyo yoshishino lokwakha.Ngenxa yamandla kunye nokuqina kwazo, zisetyenziswa ngokubanzi kwizicelo ezahlukeneyo zesakhiwo.Ukuba ukwimarikeintsimbi yolwakhiwo imiqadi H, kubalulekile ukuqonda inkqubo yemveliso kunye neentlobo ezahlukeneyo ezikhoyo ukwenza isigqibo esinolwazi.
Inkqubo yokuvelisa i-carbon steel H beam ibandakanya amanyathelo amaninzi abalulekileyo.Iqala ngokunyibilikisa imathiriyeli ekrwada efana nentsimbi ekrwada, amalahle kunye nelitye lekalika kwiziko eliqhumayo.Le nkqubo ivelisa intsimbi etyhidiweyo, ethi ke ihluzwe kwisiguquli seoksijini ukuze kususwe ukungcola nokulungelelanisa imichiza ukuze ihlangabezane nemilinganiselo efunekayo yentsimbi.
Emva kokuba intsimbi yenziwe, ibunjwa ibe yintsimbi ye-H ngokusebenzisa inkqubo ebizwa ngokuba yi-rolling.Ngethuba le nkqubo, insimbi iyafudumala kwaye idlula uluhlu lwee-roller, zenza i-H shape oyifunayo.Imiqadi ke iye isikwe ukuya kubude obufunekayo kwaye inikwe unyango olongezelelekileyo olufana nokugalela okanye ukugquma ukuqinisa ukuxhathisa kokuhlwa kunye nokuqina kuko konke.
Xa kuziwa kwiindidi ze-H-beams ezikhoyo, kukho iindlela ezininzi zokukhetha.Intsimbi ekhandisiweyo H umqadingokuqhelekileyo isetyenziselwa ukwakha kwaye yenzelwe ukuthwala imithwalo enzima.Umqadi we-galvanized H ugqunywe ngomaleko we-zinc ukuthintela ukubola, oko kuyenza ilungele ukusetyenziswa kwangaphandle okanye kwimizi-mveliso.Intsimbi yekhabhoni yentsimbi ye-H yokulala iyaziwa ngamandla ayo aphezulu kwaye idla ngokusetyenziswa kwizakhiwo kunye nezicelo zoomatshini.Ukongezelela, i-A572 A992 intsimbi ye-H intsimbi ngamabakala athile ensimbi anika amandla okwandisiweyo kwaye asetyenziswa ngokuqhelekileyo ekwakhiweni kwesakhiwo.

Ukuba ukhangelaintsimbi H imiqadi ezithengiswayo, qiniseka ukuba uzithathela ingqalelo iimfuno zakho ezithile kunye nesicelo esicetywayo.Izinto ezifana nomthamo wokuthwala umthwalo, ukuxhathisa i-corrosion kunye nokuqina ngokubanzi kufuneka kuthathelwe ingqalelo xa ukhetha uhlobo olufanelekileyo lwe-H-beam yeprojekthi yakho.
Isishwankathelo, inkqubo yokuvelisa i-H-beam ibandakanya ukunyibilika, ukucocwa, kunye nokubumba intsimbi ukwenza umqadi oqinileyo kunye nobuninzi.Imiqadi ye-H ifumaneka kwiinketho ezahlukeneyo, kubandakanywa intsimbi, i-carbon steel kunye namabakala athile ensimbi, ngoko kukho into ehambelana nayo yonke imfuno yokwakha.Ukuqonda inkqubo yokuvelisa kunye neentlobo ezahlukeneyo zexabiso lentsimbi ye-H kuya kukunceda wenze isigqibo esinolwazi xa uthenga la macandelo abalulekileyo.
