Mukuvaka nekuvaka, kushandiswa kwechiteshi chesimbi (chinowanzonzi C-chikamu simbi) kwakajairika. Idzi nzira dzakagadzirwa nesimbi uye dzakaumbwa seC, saka zita. Ivo vanowanzoshandiswa muindasitiri yekuvaka uye vane huwandu hwakawanda hwekushandisa. Kuti ive nechokwadi chekuti mhando uye zvakatemwa zveC-section simbi zvinochengetwa, American Society for Testing and Materials (ASTM) inovandudza zviyero zvezvigadzirwa izvi.
Iyo ASTM chiyero cheC-yakaita simbiinonzi ASTM A36. Iyi chiyero inovhara hunhu hwemhando yekabhoni simbi maumbirwo ekushandiswa mukuvaka riveted, bhaudhi kana welded yemabhiriji uye zvivakwa uye nezvinangwa zvakajairika. Iyi chiyero inotsanangudza zvinodikanwa pakuumbwa, zvivakwa zvemakanika uye zvimwe zvakakosha zvekabhoni simbi C-zvikamu.
Chimwe chezvakakosha zvinodiwa zveASTM A36 standard yeC-chiteshi simbiikemikari yesimbi inoshandiswa mukugadzirwa kwayo. Chiyero chinoda simbi inoshandiswa kune C-zvikamu kuti zvive nemazinga akatsanangurwa ekhabhoni, manganese, phosphorus, sarufa nemhangura. Izvi zvinodikanwa zvinovimbisa kuti simbi inoshandiswa muC-channel ine zvivakwa zvinodiwa kuti ipe simba uye kusimba kunodiwa kune zvimiro zvekushandisa.
Pamusoro pekuumbwa kwemakemikari, iyo ASTM A36 yakajairwa zvakare inotsanangura ma mechanic zvimiro zvesimbi inoshandiswa muC-chikamu simbi. Izvi zvinosanganisira zvinodiwa pakusimba kwegoho, kusimba kwesimba uye kurebesa kwesimbi. Izvi zvivakwa zvakakosha kuve nechokwadi chekuti C-channel simbi ine simba rinodiwa uye ductility kutsungirira mitoro uye kushushikana kunowanikwa mumashandisirwo ekuvaka.
Iyo ASTM A36 chiyero zvakare inovhara dimensional kushivirira uye kutwasanuka uye curvature zvinodiwa zveC-chikamu simbi. Aya maratidziro anovimbisa kuti C-zvikamu zvinogadzirwa kune iyi chiyero zvinosangana nehukuru uye chimiro chinodiwa pakushandisa kwavo kwavanoda kushandiswa mumapurojekiti ekuvaka.
Pakazere, iyo ASTM A36 yakajairwa yeC-yakaita simbi inopa yakazara seti yezvinodiwa zvemhando uye kushanda kwesimbi idzi. Nekutevedzera chiyero ichi, vagadziri vanogona kuona kuti C-zvikamu zvavanogadzira zvinosangana nezvinodiwa pakushandisa kuvaka.
Muchidimbu, iyo ASTM chiyero cheC-chiteshi simbi, inozivikanwa seASTM A36, inotsanangura zvinodikanwa zvekugadzirwa kwemakemikari, zvivakwa zvemuchina, uye kushivirira kwemasimbi aya. Nekuzadzisa izvi zvinodiwa, vagadziri vanogona kugadzira emhando yepamusoro C-zvikamu zvinosangana nemazinga anodiwa kune akasiyana siyana ekuvaka. Angave mabhiriji, maindasitiri emuchina kana zvivakwa, anoomerera kune ASTM C-chikamu simbi zviyero zvinovimbisa kuchengetedzeka uye kuvimbika kwesimbi inoshandiswa.
