Nguva pfupi yadarika, nekuenderera mberi kwekufambira mberi kwemadhorobha uye nekukwidziridzwa kwemapurojekiti akakosha ezvivakwa, kudiwa kwesimbi yekuvaka kwepamusoro kwakawedzera. Pakati pavo,H-danda, sechinhu chakakosha chinotakura mutoro mumapurojekiti ekuvaka, chave mutyairi akakosha mukusimudzira budiriro yemhando yepamusoro yeindasitiri yekuvaka, neayo emakanika zvivakwa uye nehupamhi hwemashandisirwo emamiriro ezvinhu anotungamira maitiro matsva mumusika.
Mune yakakura-yepamusoro-yepamusoro pekugara chirongwa muEast China, batch yeVAHEBHERU 150 H-matandaichangobva kuiswa muchivako chikuru chekuvaka. Seyakajairwa yeEuropean standard H-beam modhi, HEB 150 inofarirwa nezvikamu zvekuvaka kune yayo yakaenzana chikamu dhizaini, yakasimba kubhenda kuramba uye yakagadzikana inotakura mutoro. "Kuenzaniswa nezvikamu zvesimbi zvechinyakare, HEB 150 inogona kuderedza huwandu hwemajoini egungano ne30% mukuvaka, kupfupisa zvakanyanya nguva yekuvaka uku ichivimbisa kuchengetedza kwemaitiro," akadaro injinjiniya mukuru weprojekiti. Ichi chishandiso hachingoonese kukosha kunoshanda kweyakajairwa H-beam zvigadzirwa mukuvaka kwekugara, asi zvakare inopa chirevo chekusimudzirwa kwezvimiro zvesimbi muindasitiri.
Nepo mastandard modhi achishandiswa zvakanyanya,yepamusoro-inoshanda H-beam zvigadzirwainomiririrwa naASTM A572-50 H matandavari kusimudzirawo kupinda kwavo muzvirongwa zvakakosha. Zvinonzwisiswa kuti ASTM A572-50 H matanda ane yakanakisa kudzika-tembiricha kuomarara uye kusimba kwegoho, uye goho ravo rinogona kusvika kupfuura 345MPa, iyo inonyanya kukodzera mahombe-span workshops, mabhiriji emigwagwa uye mamwe mapurojekiti ane akakwira zvimiro zvinodiwa. Parizvino, mukuvakwa kwebhiriji rekuyambuka rwizi muSouth China, ASTM A572-50 H matanda akashandiswa mune yakakura truss chimiro, zvinobudirira kugadzirisa dambudziko rekutakura kumanikidzwa pasi pemamiriro ekunze akaoma uye kuve nechokwadi chehupenyu hwebasa rebhiriji.
Pamusoro pe,ASTM A572-50 yakafara flange matanda, sechigadzirwa cheH-beam, vakawedzera kuwedzera huwandu hwekushandisa hweH-beam muindasitiri yekuvaka. Nehupamhi hwayo hurefu hweflange, rudzi urwu rwedanda runogona kugovera zvirinani mutoro uye kugadzirisa kugadzikana kwechimiro. Yakave yakashandiswa zvakanyanya mukuvaka hukuru-hukuru hwekutengesa zvivako uye zvigadzirwa zvemaindasitiri mumakore achangopfuura. Mumwe munhu anotarisira bhizinesi rekugadzira simbi akati: "Muhafu yekutanga yegore rino, kurongeka kwevhoriyamu yeASTM A572-50 yakafara flange matanda yakawedzera ne40% gore negore, uye zvigadzirwa zvakatumirwawo kune dzimwe nyika kumisika yeSoutheast Asia, ikava nzvimbo itsva yekukura kwebhizinesi redu rekunze."
Indasitiri insiders yakaratidza kuti kukurumidza kukurumidza kweH-beam yekuvaka hakungoratidzi kuvandudzwa kweindasitiri yekuvaka kudiwa kwesimbi yemhando yepamusoro, asiwo inosimudzira hunyanzvi hwehunyanzvi hweindasitiri yesimbi. Mune ramangwana, nekuenderera mberi kwekuvandudzwa kwemitemo yenyika yezvivakwa zvakasvibirira uye yakaderera-kabhoni kuvaka, zvigadzirwa zveH-beam zvine basa repamusoro, kuchengetedzwa kwakawanda kwezvakatipoteredza uye kusiyanisa kwakawanda kuchaita basa rakakosha mukusimudzira kusimudzira kwemhando yepamusoro yeindasitiri yekuvaka.
