Ibicuruzwa bidasanzwe.Umubyimba ni 8-50mm, ubugari 150-625mm, uburebure bwa 5-15m, kandi ibicuruzwa bisobanurwa byegeranye cyane kugirango uhuze ibyifuzo byabakoresha, kandi birashobora gukoreshwa aho kuba isahani yo hagati, utabanje gukata, kandi birashobora gusudwa neza.
Ubuso bwibicuruzwa burasa kandi bwera.Inzira yumuvuduko ukabije wamazi ukoreshwa kunshuro ya kabiri.
Impande zombi zirahagaritse kandi inguni zirasobanutse.Igice cya kabiri cyo guhagarikwa kuzunguruka neza bizunguruka bihagaritse neza kumpande zombi, inguni zisobanutse hamwe nuburinganire bwiza bwimpande.
Igipimo cyibicuruzwa kirasobanutse neza, itandukaniro ry amanota atatu kandi itandukaniro ryurwego rumwe riruta urwego rwicyuma;ibicuruzwa biringaniye kandi biragororotse, kandi isahani ni nziza.Kuzenguruka neza bifata inzira ikomeza, kuzunguruka byikora byikora byikora kugirango harebwe niba nta byuma bifata kandi nta gukurura ibyuma, uburinganire buringaniye bwibicuruzwa, urwego rwihanganirwa, itandukaniro ryamanota atatu, itandukaniro ryicyiciro kimwe, umuhoro wunamye nibindi bipimo biruta icyicaro isahani, kandi isahani igororotse ni nziza.Ubukonje bukonje, uburebure buringaniye buringaniye.
Ibicuruzwa byemeza ubuziranenge bwigihugu, kimwe nicyuma.Ibipimo byiza na tekiniki byateguwe kandi bigakorwa ukurikije YB / T4212-2010 (Q345B / Q235B bivuga GB / T1591-94.
1. Icyuma gishyushye gishyushye nicyuma kirekire, gishobora kuzunguruka hamwe nu mpande enye zingana kugirango zikoreshwe muri rusange.Ibisobanuro byayo bigaragarira muri milimetero z'ubugari * ubugari.Ibyuma bya flat birashobora kurangira ibyuma, bikoreshwa mubice, urwego, ibiraro nuruzitiro, nibindi.. .Imiterere yo gutanga: Ibyuma bitangwa bitangwa mu tubari tugororotse.Igipimo: Icyuma kiringaniye cy'uburebure butajegajega hamwe n'uburebure bw'abasore bitangwa n'uburemere bwa theoretical.
2. icyuma gihimbano gihimbwe icyapa kirekire hamwe nicyerekezo cyurukiramende.Guhimba ntibishobora gusa kubona imiterere nubunini bwibagirwa gusa, ariko birashobora no kunoza cyane ishyirahamwe ryibyuma, kuzamura ubwinshi bwibyuma;Irashobora guhindura ikwirakwizwa rya fibre organisation, ikuraho anisotropy, itezimbere imiterere yubukorikori bwicyuma, kugirango imbaraga nubukomezi bwibyuma bitezimbere;kandi irashobora gutunganywa plastike iri munsi yicyuma kinini nicyuma kinini.Icyuma gihimbano ni icyuma cyiza cyane cyo mu rwego rwo hejuru, gikoreshwa cyane cyane kumasoko, ibikoresho nibice byingenzi byubukanishi.Ibisobanuro by'ibyuma bihimbano bigaragarira muri mm y'ubugari * ubugari, naho ibisobanuro ni 20mm * 40mm ~ 160mm * 300mm.ibipimo ngenderwaho: GB / T16761-1
Igice cy'icyuma ni bumwe mu bwoko bune bw'ibyuma (isahani, umuyoboro, ubwoko, insinga).Ukurikije imiterere yicyiciro, igice cyicyuma kigabanyijemo ibice byoroheje byicyuma nicyiciro cyicyuma (igice cyicyuma).Iyambere yerekeza ku cyuma cya kare, ibyuma bizunguruka, ibyuma biringaniye, ibyuma bifatika, ibyuma bitandatu, nibindi.;ibyanyuma bivuga I-beam, umuyoboro wibyuma, gari ya moshi, idirishya ryamadirishya, ibyuma byunamye, nibindi.
Icyuma cya kare - icyuma cya kare, ibyuma bishyushye kandi bikonje;ubushyuhe bushyushye bwa kare kare uburebure bwa 5-250mm;ubukonje-bushushanyije kare kare impande 3-100mm.
Icyuma kizengurutse - igice kizengurutse ibyuma, kigabanyijemo ibice bishyushye, byahimbwe kandi bikonje bikonje bitatu, bishyushye bizunguruka ibyuma bya diametre 5-250mm, muri byo 5-9mm bikunze gukoreshwa nkibikoresho fatizo byo gushushanya insinga zicyuma, bita inkoni ;nko mubisahani bitanga nabyo byitwa coil-roll coil.Ibyuma bizengurutse ibyuma bigororotse ni binini, bikoreshwa nka fagitire ya shaft.Ubukonje bushushanyijeho ibyuma bya diametre 3-100mm, uburebure buringaniye.
Inguni y'icyuma - igabanijwemo ubwoko bubiri bw'ibyuma bingana kandi bitangana.Ibisobanuro by'ibyuma bigaragazwa n'ubunini bw'uburebure bw'uruhande n'ubugari bw'uruhande.Mubisanzwe ibisobanuro byibyuma byakozwe ni No 2-20, ni ukuvuga umubare wa santimetero z'uburebure.Nka No 5 ibyuma bingana ibyuma byerekana uburebure bwuruhande rwa 5cm (50mm).Umubare umwe w'inguni akenshi ufite 2-7 zitandukanye.
Uburyo bwo kubara uburemere bwibyuma
Icyuma kibase: uburemere kuri metero = 0.00785 * ubugari * ubugari bwuruhande
