Iindaba-Intsimbi emile okwe-H: iNtsebenzo egqwesileyo, uLwakhiwo lwezicelo ezininzi zomqolo wentsimbi.

Kwintsimi yolwakhiwo lwangoku kunye noshishino,Intsimbi yeCarbon eQhelekileyo eqengqelekayo yeHifana nenkwenkwezi ekhanyayo, kunye nokusebenza kwayo okugqwesileyo kunye noluhlu olubanzi lwezicelo, iye yaba yinto ekhethwayo kwiiprojekthi ezininzi ezinkulu.

Ubume obukhethekileyo be-cross-section ye-H-shaped steel inika iipropati ezingaqhelekanga zemishini. I-flange ebanzi kunye ne-parallel kunye nobukhulu obufanelekileyo bewebhu buyenza ivelele ekuthwaleni umthamo. Nokuba luxinzelelo oluthe nkqo, okanye umoya othe tye, amandla enyikima kunye neminye imithwalo, intsimbi ye-H inokumelana ngokulula nayo. Idatha yovavanyo ibonisa ukuba phantsi kweemeko ezifanayo, xa kuthelekiswa nemigangatho ye-I eqhelekileyo, umthamo wokuthwalaIntsimbi yeCarbon H Beaminokunyuswa ngaphezu kwe-30%, ngelixa ubunzima bayo bunokuncitshiswa malunga ne-20%, ephucula kakhulu ukusebenza kakuhle kokusetyenziswa kwezinto.

Ngenxa yokusebenza kwayo okugqwesileyo,Welding H Beamisetyenziswa kuluhlu olubanzi lwezicelo. Kwintsimi yoshishino, ukwakhiwa kweefektri ezinkulu kuphantse kwahlulwa kwintsimbi efana ne-H. Njengomatshini wokuvelisa imoto, isityalo sayo esiphakamileyo sidinga isakhiwo esinamandla senkxaso, iikholamu zetsimbi ezinokwakheka kwe-H kunye nemiqadi, ezinokuthwala ngokukhuselekileyo ubunzima bezixhobo ezinkulu phezulu kwisityalo nangaphakathi, kunye nokuqinisekisa ukuzinza kwendawo yokuvelisa. Kwiindawo zorhwebo, uyilo lwendawo evulekileyo yamaziko okuthenga amakhulu aneemfuno eziphezulu kakhulu zokuthwala umthwalo kunye nesithuba sendawo yezinto. Intsimbi emile okwe-H ifezekisa indawo enkulu yekholamu-ekhululekileyo ngenxa yeenzuzo zayo, ukudala indawo yokuthenga evulekileyo kunye nekhululekile kubathengi.

Kwisakhiwo sentsimbi yesakhiwo,Ulwakhiwo lwentsimbi H Beamidlala indima ebalulekileyo engenakubuyiselwa. Ukusebenza kwayo kakuhle kwe-welding kwenza inkqubo yokwakha isebenze kwaye ikhawuleze. Abasebenzi bokwakha banokukhawuleza badibanise imiqadi ye-H kwisakhelo sokwakha esomeleleyo, banciphise kakhulu umjikelo wokwakha. Ukuthatha isakhiwo seofisi ephezulu kwisixeko njengomzekelo, ityhubhu engundoqo kunye nesakhiwo sesakhelo esakhiwe ngentsimbi emise okwe-H ayinikezeli nje kuphela umthamo oqinileyo wokuthwala othe nkqo kwisakhiwo, kodwa unokuxhathisa ngokufanelekileyo amandla omoya othe tye kunye nomoya. Kwezinye iindawo ezithandwa ziinyikima, izakhiwo ezakhiwe ngentsimbi emile okwe-H zibonisa ukusebenza kakuhle kwenyikima kwiinyikima, kwaye zandisa ukhuseleko lobomi babantu kunye nepropathi.

Ukongeza, intsimbi efana ne-H nayo idlala indima ebalulekileyo ekwakhiweni kwebhulorho. Ingaba ibhuloho enkulu ewela umlambo okanye i-overpass kwisixeko, izibonda zensimbi ezenziwe ngentsimbi ye-H zinokumelana nomthwalo omkhulu wesithuthi kunye novavanyo lwamandla endalo ukuqinisekisa ukhuseleko kunye nokuzinza kwebhuloho.

Ukushwankathela, insimbi ene-H ishiye uphawu olunzulu kwiindawo zokwakha kunye nezoshishino kunye nokusebenza kwayo okugqwesileyo kunye noluhlu olubanzi lwezicelo. Ngenkqubela phambili eqhubekayo yesayensi kunye nobuchwepheshe kunye nophuhliso olukhulayo lobuchwephesha bobunjineli, intsimbi ye-H-beam ngokuqinisekileyo iya kudlala indima ebalulekileyo kwiinkalo ezininzi kwaye ibe negalelo ngakumbi ekwakhiweni kwabantu.
