Iindaba - Iinqwaba zePhepha leNtsimbi: Iintlobo, Ubungakanani kunye nokusetyenziswa okubalulekileyo

Kwinjineli yezakhiwo, iinqwaba zentsimbi zibalulekile kwizakhiwo ezizinzileyo nezihlala ixesha elide—kwayeiinqwaba zeshiti zentsimbiZihlukile ngokuguquguquka kwazo. Ngokungafaniyo neengqumba zentsimbi zemveli (ezigxile ekudluliseleni umthwalo), iingqumba zamaphepha zibalasele ekubambeni umhlaba/amanzi ngelixa zixhasa imithwalo, ngenxa “yezihluthulelo” zazo ezidibeneyo. Apha ngezantsi sisikhokelo esilula seentlobo zazo, ubungakanani obuqhelekileyo, kunye nokusetyenziswa okusebenzayo.

Iintlobo zeeNqwaba zePhepha zeNsimbi

Iinqwaba zeeshiti zahlulwe zibe ziindidi ezimbini eziphambili zokwenza: ezigoqwe ngobushushu kunye nezibandayo, nganye inoyilo lohlobo lwe-U kunye nolwe-Z.

Zenziwe ngokufudumeza intsimbi ngaphezulu kwe-1,000°C kwaye ziyiqengqele zibe yimo, ezi nqwaba ziqinile, zihlala ixesha elide, kwaye zilungele iiprojekthi ezinkulu, zexesha elide.

Ishushu EqengqelekayoInqwaba yePhepha lohlobo lwe-U: I-“U” cross-section yayo (ii-parallel flanges + web) inika ukufakelwa okulula—nokuba kusemhlabeni oxineneyo. Izinzile kakhulu ecaleni, ifanelekile ekubambeni iindonga okanye ekuxhaseni ukumba. Indawo yangaphakathi ye-U-shape ingazaliswa ngekhonkrithi ukuze ibe namandla angakumbi.

Ishushu EqengqelekayoInqwaba yeSheet yeCandelo le-Z: Ifana no-“Z,” iiflange zayo zijonge kwicala elichaseneyo, kunye neengcango ezikwimiphetho engaphandle. Oku kudala ububanzi obubanzi obusebenzayo, ngoko ke iinqwaba ezimbalwa zigubungela indawo (ukunciphisa iindleko). Iyamelana namandla amakhulu asecaleni, nto leyo eyenza ukuba ibe ntle kakhulu ekugrumbeni nzulu okanye emsebenzini wonxweme lomlambo.

Iinqwaba zePhepha zeNsimbi ezenziwe ngoBubandayo

Zenziwe ngentsimbi esicaba kubushushu begumbi (akukho bushushu), ezi zikhaphukhaphu, zitshiphu, kwaye zingcono kwiiprojekthi ezincinci/zexesha elifutshane (nangona zingenamandla kangako kuneziqengqelekayo ezishushu).

Inqwaba yephepha le-U eyenziwe ngombala obandayo: Incinci kune-hot-rolled U-types, kulula ukuyithutha nokuyifakela. Yisebenzisele udonga olugcina ixeshana, ucingo lwegadi, okanye izithintelo ezincinci zezikhukula—ilungele iiprojekthi ezingabizi kakhulu.

Inqwaba yePhepha leCandelo le-Z elenziwe ngoBubandayo: Ifana no-“Z” kodwa iguquguquka ngakumbi. Ifanelekile kwiindawo zexeshana (umz., imida yokwakha) kuba kulula ukuyisusa kwaye iyakwazi ukuqhelana nentshukumo encinci yomhlaba.

Ubungakanani obuqhelekileyo

Ubungakanani buxhomekeke kwiimfuno zeprojekthi, kodwa le yimigangatho yoshishino:

Inqwaba yePhepha lohlobo lwe-U:
400mm × 100mm: Incinci kwiindawo ezixineneyo (iindonga ezincinci zokukhusela, umphetho wegadi).
400mm × 125mm: Mde kakhulu kwimisebenzi ephakathi (ukwemba kwiindawo zokuhlala, imiqobo emincinci yezikhukula).
500mm × 200mm: Umsebenzi onzima kwiindawo zorhwebo (ukwemba nzulu, iindonga ezihlala zihleli).

Inqwaba yeSheet yeCandelo le-Z: 770mm×343.5mm yeyona nto ifanelekileyo. Uyilo lwayo olubanzi lugubungela iindawo ezinkulu, kwaye lomelele ngokwaneleyo ukuqinisa unxweme lomlambo okanye ukulawula izikhukula ezinkulu.

Izicelo eziphambili

Iimfumba zesinyithi zentsimbi ziyakhanya kwiiprojekthi zokwenyani ezifana nezi:

Iindonga zoMkhuseli woMlamboIintlobo ze-U/Z eziqengqelekayo ezishushu ziqinisa iibhanki ukuze ziyeke ukukhukuliseka. Amandla azo ayamelana namandla amanzi, kwaye amaqhina adibeneyo agcina umhlaba usendaweni yawo.

Iindonga (Ukugcina kunye noMda)Ii-U-types ezenziwe ngobandayo zisebenza kwiindonga zokuhlala; ii-U/Z ezigoqwe ngobushushu zibamba iindonga zorhwebo (umz., ezijikeleze iivenkile ezinkulu). Izitshixo zenza zingangeni manzi, zithintele umonakalo wamanzi.

Ulawulo lweZikhukulaIintlobo ze-Z ezigoqekileyo zakha imiqobo enamandla yezikhukula; ezo zenziwe ngokubanda zikhawuleza ukufakwa kwiimeko ezingxamisekileyo (umz., ukugaleleka kwesiphango). Zombini zigcina amanzi engangeni ngokufanelekileyo.

Kutheni Ukhetha Iingqumba Zeeshiti Zentsimbi?
Zihlala ixesha elide (zihlala iminyaka engaphezu kwama-50), kulula ukuzifaka, kwaye zisebenza kakuhle ixesha elide. Ngeentlobo/ubukhulu obahlukeneyo, zilungele phantse nayiphi na iprojekthi yokugcina okanye yokulayisha.
Ngexesha elizayo xa ubona udonga olugcina izinto okanye umqobo othintela izikhukula, kusenokwenzeka ukuba uxhaswa kukuthembeka kweenqwaba zeeshiti zentsimbi!
