Iyintoni imfuno yemarike yeentsimbi ze-H-miqadi?

Intsimbi yentsimbi H (ekwaziwa njengentsimbi emile okwentsimbi engu-H) inemfuno ekhulayo yemarike ngenxa yokuguquguquka kwayo kunye nokuqina.Intsimbi ye-H isetyenziswa ngokubanzi kulwakhiwo, iziseko zophuhliso kunye neeprojekthi zoshishino, okwenza kube yinto efunwayo kwiimarike.
Enye yezinto eziphambili eziqhubayointsimbi H-imiqadiimfuno yemarike ngamandla ayo kunye nomthamo wokuthwala umthwalo.Eyilwe ukuxhasa imithwalo enzima, intsimbi yokusila i-h beam ilungele ukusetyenziswa kwezakhiwo ezifana nezakhelo zokwakha, iibhulorho kunye neendonga zokugcina.Isakhiwo sentsimbi ye-H siyakwazi ukumelana namanqanaba aphezulu oxinzelelo kunye noxinzelelo, okwenza kube yinto yokuqala yokukhetha iinjineli kunye nabakhi bezakhiwo.
Enye into kwimfuno ekhulayo yentsimbi yentsimbi yentsimbi ye-H kukuguquguquka kwayo.Le miqadi ifumaneka ngobukhulu obahlukeneyo kunye nemilinganiselo efana ne-10m yentsimbi ye-H beam kunye200×150 intsimbi H umqadiukuhambelana neemfuno zeeprojekthi ezahlukeneyo.Ingaba ukwakha izakhiwo zetsimbi, ukugcina iintsika zodonga okanye ukuxhasa oomatshini boshishino, ii-H-beams zibonelela ngokuguquguqukayo kuyilo kunye nokusetyenziswa.
Ukongeza, umgangatho wentsimbi h umqadi ugcina isithuba sodonga ngumqhubi obalulekileyo wemfuno yemarike.I-Factory H steel beam yenziwe kwimigangatho engqongqo yoshishino, iqinisekisa umgangatho ophezulu kunye nokusebenza okungaguqukiyo.Iintsimbi ze-Galvanized H-beams nazo ziyafumaneka, zinika ukuxhathisa ukubola kunye nobomi benkonzo ende, efanelekileyo kwizicelo zangaphandle kunye nolwandle.
Imfuno yemarike yensimbi efana ne-H nayo ichaphazeleka yindleko yayo.Xa kuthelekiswa nezinye izinto, le miqadi inikezela ngesisombululo esineendleko zokuxhasa izakhiwo, okwenza kube yinto ekhangayo kwiiprojekthi zokwakha kunye neziseko.

Isishwankathelo, imfuno yemarike yeintsimbi yentsimbi H umqadiiqhutywa ngamandla ayo, ukuguquguquka, umgangatho kunye nokusebenza kakuhle kweendleko.Njengoko icandelo lokwakha nelemizi-mveliso liqhubeka nokukhula, imfuno yezinto ezithembekileyo nezihlala ixesha elide njengemiqadi ye-H kulindeleke ukuba yonyuke, izenze zibe yimpahla exabisekileyo kwimarike.
