Muva nje, ngentuthuko eqhubekayo yokwakhiwa kwamadolobha kanye nokusheshiswa kwamaphrojekthi engqalasizinda abalulekile, isidingo sensimbi yokwakha esebenza kahle sikhuphuke kakhulu. Phakathi kwazo,Ukukhanya kwe-H, njengengxenye eyinhloko ethwala umthwalo kumaphrojekthi okwakha, isibe ngumshayeli oyinhloko wokukhuthaza intuthuko yekhwalithi ephezulu embonini yokwakha, ngezakhiwo zayo ezinhle kakhulu zemishini kanye nezimo zokusetshenziswa ezibanzi eziholela ekuthambekeni okusha emakethe.
Kuphrojekthi enkulu yokuhlala enezitezi eziphakeme eMpumalanga yeShayina, iqembu labantuISIHEB 150 Imisebe ye-Hmuva nje ifakiwe ekwakhiweni kwesakhiwo esiyinhloko. Njengemodeli ejwayelekile yaseYurophu ye-H-beam, i-HEB 150 ithandwa amayunithi okwakha ngenxa yokwakheka kwayo kwesigaba esilinganiselayo, ukumelana okunamandla kokugoba kanye nomthamo ozinzile wokuthwala umthwalo. "Uma kuqhathaniswa nezingxenye zensimbi zendabuko, i-HEB 150 inganciphisa inani lamajoyinti okuhlanganisa ngo-30% enkambisweni yokwakha, inciphise kakhulu isikhathi sokwakha ngenkathi iqinisekisa ukuphepha kwesakhiwo," kusho unjiniyela oyinhloko wephrojekthi. Lolu hlelo lokusebenza alugcini nje ngokuqinisekisa inani elisebenzayo lemikhiqizo ejwayelekile ye-H-beam ekwakhiweni kwezindlu, kodwa futhi lunikeza inkomba yokukhuthazwa kwezakhiwo zensimbi ezijwayelekile embonini.
Nakuba amamodeli ajwayelekile esetshenziswa kabanzi,imikhiqizo ye-H-beam esebenza kahle kakhuluimelelwe yiImisebe ye-ASTM A572-50 Hfuthi ziyasheshisa ukungena kwazo kumaphrojekthi abalulekile. Kuyaqondakala ukuthi imishayo ye-ASTM A572-50 H inokuqina okuhle kakhulu kokushisa okuphansi kanye nokumelana nokugqwala, futhi amandla ayo okukhiqiza angafinyelela ngaphezu kwama-345MPa, okulungele kakhulu ama-workshop amakhulu, amabhuloho omgwaqo omkhulu kanye neminye imisebenzi enezidingo eziphezulu zesakhiwo. Njengamanje, ekwakhiweni kwebhuloho eliwela umfula eNingizimu yeShayina, imishayo ye-ASTM A572-50 H isetshenziswe esakhiweni esiyinhloko se-truss, ixazulula ngempumelelo inkinga yokucindezela kokuthwala ngaphansi kwezimo zezulu eziyinkimbinkimbi futhi iqinisekisa impilo yenkonzo yebhuloho.
Ngaphezu kwalokho,Imisebe ye-flange ebanzi ye-ASTM A572-50, njengomkhiqizo osuselwa ku-H-beam, ikhulise kakhulu ububanzi bokusetshenziswa kwe-H-beam embonini yokwakha. Ngobubanzi bayo obukhulu be-flange, lolu hlobo lwe-beam lungasabalalisa kangcono umthwalo futhi luthuthukise ukuzinza kwesakhiwo. Lusetshenziswe kabanzi ekwakhiweni kwezakhiwo ezinkulu zezentengiselwano kanye nezitshalo zezimboni eminyakeni yamuva nje. Umuntu ophethe ibhizinisi lokukhiqiza insimbi uthe: "Engxenyeni yokuqala yalo nyaka, inani le-oda le-ASTM A572-50 wide flange beams likhuphuke ngo-40% unyaka nonyaka, futhi imikhiqizo nayo ithunyelwe ezimakethe zaseNingizimu-mpumalanga ye-Asia, yaba yindawo entsha yokukhula kwebhizinisi lethu lokuthumela kwamanye amazwe."
Abangaphakathi embonini baveze ukuthi intuthuko esheshayo ye-H-beam yokwakha ayibonisi nje kuphela ukuthuthukiswa kwesidingo semboni yokwakha sensimbi esezingeni eliphezulu, kodwa futhi ikhuthaza ukusungulwa kobuchwepheshe embonini yensimbi. Esikhathini esizayo, ngokuthuthukiswa okuqhubekayo kwezindinganiso zikazwelonke zezakhiwo eziluhlaza kanye nokwakhiwa okunekhabhoni ephansi, imikhiqizo ye-H-beam esebenza kahle kakhulu, ukuvikelwa kwemvelo okwengeziwe kanye nokwehlukahluka okwengeziwe kuzodlala indima ebaluleke kakhulu ekukhuthazeni intuthuko esezingeni eliphezulu yemboni yokwakha.
