Beam ophuma zokwakha

Beam metal libhekisela uhlobo olulodwa metal ophezulu ezikumgangatho isetyenziswa ikakhulu ukwenza izakhiwo elide-kubude kwezakhiwo nakumashishini, unga nciphisa ngokubaluleka umthwalo ngokubanzi kubume wenqwelwana kwaphuma. Namhlanje yenye yeendima ezibalulekileyo zonke iisayithi umsebenzi, kwezixhaso nendwe, iibrorho, imigangatho kunye nezinye iintlobo zezakhiwo ngentsimbi.

uhlobo ngalunye kwemveliso uneempawu zawo ngamnye, elikuvumela ukuba wenze ukhetho olufanelekileyo. Ke kufuneka zihambelane neemfuno iinkcukacha ukuba bakwazi ukuyila izakhiwo eziyimfuneko. Xa zokwakha mihla umqadi sobhedu isetyenziswa ngokubanzi. ukukhethwa kwayo isekelwe khrayitheriya ezifana ubungakanani beendonga, ezishelifini imbonakalo.

Bokwenziwa beam metal kwiintlobo ezimbini ezisisiseko. Umahluko ephambili kuxhomekeke kwemilo ezahlukeneyo yayo cross-candelo - i T-umqadi yaye mna-nomqadi. Tee, ukuba ukhangela esiphelweni, ifuze ileta "T", ngoxa kabini-tee - unobumba "N" okanye kabini zocaphulo "T", apho ke, yaba igama layo. Eyona endle isicelo kwaba bobabini - njengoko ethwele nemigangatho yamagumbi izakhiwo kunye nezakhiwo ukulungiselela iinjongo ezahlukeneyo.

Ngentsimbi umqadi yokwakha inceda emi- umthwalo phezu kweziseko ezixhasa. Bathi ke kugqitha kuyo ngokulinganayo phezu kwesiseko. Beam steel luhlobo amathambo isakhiwo, ngokuthe ngcembe zezinye izinto zokwakha noshowo. Kungenxa yoko eyimveliso eziqalelo iimfuno ezizodwa esemgangathweni. Classification metal yale hlobo isekelwe kwiimpawu zobugcisa:

• ngokungqinelana nefom apho kuye;

• Ebubanzini ezishelifini neendonga;

• ngokuxhomekeke lungiselelo ezishelifini ubuso;

• impahla eyayisetyenziswa xa isenziwa.

Ukongeza, imiqadi intsimbi eyahlukileyo injongo kunye nendlela ngawo.

Le umqadi unako ngokuba uhlobo umqadi ube mnye, nto leyo eye iindidi zobungakanani kunye necandelo cross. It wadalelwa ukuba kungenzeka lonikezelo umthwalo kweziseko ezixhasa ngokulinganayo kujikelezo kwesakhiwo sisephantsi kolwakhiwo. Kutsha nje lifumene ukwanda metal I-umqadi ube mnye, leyo ngokubanzi asetyenziswe ekwakheni viaducts, iibhulorho, hangars, izitora, ndingasathethi izinto ukusetyenziswa mveliso kunye yoluntu.

Enye ingongoma ebalulekileyo ekusebenziseni ukhetho kulwakhiwo ukubala oluchanekileyo imiqadi yesinyithi. Enoba umbandela, ezifana cross-candelo kunye nohlobo kokwakhiwa izibalo zalo yenziwe yi algorithm mnye. Ekuqaleni, lo scheme uyilo senziwa, ngoko ke imikhosi zangaphakathi olumiswe lwagqitywa. inyathelo elilandelayo - ziinzame lwangaphakathi ekhethiweyo cross-candelo umqadi kwinqanaba lokugqibela, ukukhangela zonke iziphumo. Ukuqinisekiswa ikuvumela ukuba ukwandisa okanye ukunciphisa umnqamlezo-icandelo ukuze kuphunyezwe ngomlinganiselo ngokupheleleyo amandla.
