Izindaba - Construction-Grade H-imishayo: A Core Driver Fueling High-Quality Industry Development

Muva nje, ngokuthuthuka okuqhubekayo kokuthuthuka kwezindawo zasemadolobheni kanye nokusheshisa kwemiklamo ebalulekile yengqalasizinda, isidingo sensimbi yokwakha esebenza kahle siye sanda. Phakathi kwazo,I-H-beam, njengengxenye ewumgogodla ethwala umthwalo kumaphrojekthi wokwakha, isibe umshayeli oyinhloko ekukhuthazeni intuthuko yekhwalithi ephezulu yemboni yezokwakha, enezakhiwo zayo ezinhle kakhulu zokusebenzisa imishini kanye nezimo ezibanzi zokusetshenziswa okuholela kumkhuba omusha emakethe.

Kuphrojekthi enkulu yokuhlala enezitezi eziphakeme eMpumalanga China, iqoqo leI-HEB 150 I-H-imishayoisanda kufakwa ekwakhiweni kwesakhiwo esikhulu. Njengemodeli evamile yaseYurophu ye-H-beam, i-HEB 150 ithandwa amayunithi okwakha ngomklamo wayo wesigaba olinganiselayo, ukumelana nokugoba okuqinile kanye nomthamo ozinzile wokuthwala umthwalo. “Uma kuqhathaniswa nezingxenye zensimbi ezivamile, i-HEB 150 inganciphisa inani lamajoyinti ahlanganisayo ngo-30% ohlelweni lokwakha, ifinyeze kakhulu isikhathi sokwakha kuyilapho iqinisekisa ukuphepha kwesakhiwo,” kusho unjiniyela omkhulu wephrojekthi. Lolu hlelo lokusebenza aluqinisekisi kuphela inani elisebenzayo lemikhiqizo ejwayelekile ye-H-beam ekwakhiweni kwezindawo zokuhlala, kodwa futhi inikeza ireferensi yokukhuthazwa kwezakhiwo zensimbi ezijwayelekile embonini.

Nakuba amamodeli ajwayelekile asetshenziswa kabanzi,imikhiqizo ephezulu ye-H-beamemelelwe nguI-ASTM A572-50 H imishayoziphinde zisheshise ukungena kwazo kumaphrojekthi abalulekile. Kuyaqondakala ukuthi imishayo ye-ASTM A572-50 H inokuqina okuhle kakhulu kwezinga lokushisa eliphansi kanye nokumelana nokugqwala, futhi amandla ayo okukhiqiza angafinyelela ngaphezu kuka-345MPa, elungele ikakhulukazi ama-workshops amakhulu, amabhuloho omgwaqo kanye namanye amaphrojekthi anezidingo eziphezulu zesakhiwo. Njengamanje, ekwakhiweni kwebhuloho eliwela umfula eNingizimu China, imishayo ye-ASTM A572-50 H isetshenziswe esakhiweni esiyinhloko se-truss, ukuxazulula ngokuphumelelayo inkinga yokuthwala ingcindezi ngaphansi kwezimo zezulu eziyinkimbinkimbi nokuqinisekisa impilo yesevisi yebhuloho.

Ngaphezu kwalokho,I-ASTM A572-50 imishayo ye-flange ebanzi, njengomkhiqizo osuselwe ku-H-beam, baye banweba ngokwengeziwe ububanzi bokusetshenziswa kwe-H-beam embonini yezokwakha. Ngobubanzi bayo obubanzi be-flange, lolu hlobo lwesigxobo lungasabalalisa kangcono umthwalo futhi luthuthukise ukuzinza kwesakhiwo. Isetshenziswe kabanzi ekwakhiweni kwezakhiwo ezinkulu zezentengiselwano nezitshalo zezimboni eminyakeni yamuva. Umuntu ophethe ibhizinisi lokukhiqiza insimbi uthe: "Engxenyeni yokuqala yalo nyaka, umthamo we-oda we-ASTM A572-50 ububanzi be-flange beams ukhuphuke ngo-40% unyaka nonyaka, futhi imikhiqizo iphinde yathunyelwa ezimakethe zaseNingizimu-mpumalanga ye-Asia, ibe yindawo entsha yokukhula kwebhizinisi lethu lokuthumela ngaphandle."

Abangaphakathi embonini baveze ukuthi ukuthuthukiswa okusheshayo kwe-H-beam yokwakha akubonisi nje kuphela ukuthuthukiswa kwesidingo semboni yezokwakha ngensimbi yezinga eliphezulu, kodwa futhi kukhuthaza ukusungulwa kwezobuchwepheshe embonini yensimbi. Esikhathini esizayo, ngokuthuthukiswa okuqhubekayo kwamazinga kazwelonke ezakhiwo eziluhlaza kanye nokwakhiwa kwekhabhoni ephansi, imikhiqizo ye-H-beam esebenza kahle, ukuvikelwa kwemvelo okwengeziwe kanye nokuhlukahluka okuningi kuzodlala indima ebaluleke kakhulu ekukhuthazeni ukuthuthukiswa kwekhwalithi ephezulu yemboni yezokwakha.
