Ubwoko n'ibipimo by'icyuma

I. Isahani y'icyuma n'umukandara
Isahani y'icyumaIgabanyijemo icyuma kinini, icyuma gito n'icyuma gifunganye, imiterere yacyo ifite ikimenyetso "a" n'ubugari x ubugari x uburebure muri milimetero. Urugero: 300x10x3000 ubugari bwa 300mm, ubugari bwa 10mm, uburebure bwa 3000mm.

Isahani y'icyuma ifite ubunini: ubugari burenga 4mm, ubugari 600~3000mm, uburebure 4~12m.
Isahani y'icyuma nto: ubugari buri munsi ya 4mm, ubugari 500~1500mm, uburebure 0.5~4m.
Icyuma giteretse:ubugari 4 ~ 60mm, ubugari 12 ~ 200mm, uburebure 3 ~ 9m.
Amasahani y'icyuma n'imirongo bishyirwa mu byiciro hakurikijwe uburyo bwo kuzingurura:amasahani akonje azungurutsenaamasahani ashyushye azingiye; hakurikijwe ubunini: amasahani y'icyuma yoroshye (munsi ya 4mm), amasahani y'icyuma afite ubunini (4-60mm), amasahani afite ubunini burenze (hejuru ya 60mm)

2. icyuma gishyushye cyane
2.1I-beam
I-beam steel nkuko izina ryayo ribigaragaza, ni imiterere y'igice cya I, flange zo hejuru n'izo hepfo zirashaje.
I-beam steel igabanyijemo amoko atatu y'ubugari busanzwe, bworoheje n'ubw'amababa, hamwe n'ikimenyetso "akazi" n'umubare wa said. Ni iyihe nomero ihagarariye uburebure bw'igice cy'umubare wa santimetero. 20 na 32 hejuru y'umuraba usanzwe wa I, umubare umwe kandi ugabanyemo ubwoko bwa a, b na a, b, c, ubugari bw'urukuta rwayo n'ubugari bwa flange buri hejuru ya 2mm. nka T36a ko uburebure bw'igice cy'urukuta bwa mm 360, ubugari bw'urukuta rw'ubwoko bw'umuraba usanzwe wa I. I-beams zigomba kugerageza gukoresha ubugari bw'urukuta rworoshye cyane rw'ubwoko bwa a, bitewe n'uburemere bwarwo bworoshye, mu gihe igihe cy'urukuta rw'urukuta rw'urukuta ari kinini.
Igihe cy'uburemere n'uburebure bw'imirasire ya I mu cyerekezo cy'ubugari ni bito cyane ugereranyije n'ibiri mu cyerekezo cy'uburebure. Bityo, hari imbogamizi zimwe na zimwe mu ikoreshwa, muri rusange zikwiriye ku ngingo zigonda icyerekezo kimwe.
3.icyuma cy'umuyoboro
Ibyuma byo mu muhanda bigabanyijemo ubwoko bubiri bw'icyuma gisanzwe n'icyuma cyoroshye. Ubwoko bw'icyuma cyo mu muhanda gifite ikimenyetso “[””] n'umubare wa said. Kimwe n'umuraba wa I, umubare wa santimetero nawo ugaragaza uburebure bw'igice cyo hejuru. Nka [20 na Q [20] uko bikurikirana, mu izina ry'uburebure bw'igice cya mm 200 cy'icyuma gisanzwe n'icyuma cyoroshye. 14 n'ibyuma birenga 24 bisanzwe, umubare umwe w'ubwoko bwa sub-a, b na a, b, c, ibisobanuro byacyo hamwe n'umuraba wa I.

 

4. icyuma cy'inguni
Ibyuma by'inguni bigabanyijemo ubwoko bubiri bw'icyuma cy'inguni kiringaniye n'icyuma cy'inguni kitaringaniye.
Inguni iringaniye: amaguru yayo abiri agororotse afite uburebure bungana, icyitegererezo cyayo gifite ikimenyetso "L" n'ubugari bw'ingingo x ubugari bw'ingingo muri milimetero, nka L100x10 ku bugari bw'ingingo bwa mm 100, ubugari bw'ingingo bwa mm 10.
Inguni zitangana: amaguru yayo abiri agororotse ntabwo angana, icyitegererezo gifite ikimenyetso "" n'ubugari bw'amaguru maremare x ubugari bw'amaguru magufi x ubugari bw'amaguru muri milimetero, nka L100x80x8 ku bugari bw'amaguru maremare bwa 100mm, ubugari bw'amaguru magufi bwa 80mm, ubugari bw'amaguru bungana na milimetero 8.

 
5. Umurabyo wa H(zizungurutse kandi zisutswe)
Umuraba wa H utandukanye na I-beam.
(1) umugozi mugari, bityo habayeho umugozi mugari wa I-beam.
(2) Ubuso bw'imbere bw'urukiramende ntibugomba kugira ubuhaname, ubuso bwo hejuru n'ubwo hasi buringaniye.
(3) uhereye ku buryo bwo gukwirakwiza ibikoresho, igice cya I-beam cy’ibikoresho kiba cyiganjemo urushundura, uko icyuma kinini kigera ku mpande z’inyongera, icyuma gito, n’umuraba wa H-beam uzungurutse, ni ko gukwirakwiza ibikoresho biba ku nkengero z’igice.
Kubera iyo mpamvu, imiterere y’igice cya H-beam iraruta cyane akazi gasanzwe, umuyoboro, inguni hamwe n’uburyo bihuriramo ibice byacyo, ikoreshwa ry’umusaruro mwiza mu bukungu.
Dukurikije ibipimo ngenderwaho by’igihugu ubu “Hot rolled H-beam and section T-beam” (GB/T11263-2005), H-beam igabanyijemo ibyiciro bine, bigizwe n’ibi bikurikira: wide flange H-beam - HW (W for Wide English prefix), ibisobanuro kuva kuri 100mmx100mm ~ 400mmx400mm; middle flange H-beam - HM (M for Middle English prefix), ibisobanuro kuva kuri 150mmX100mm ~ 600mmX300mm: Narrow Cui-edge H-beam - HN (N for Narrow English prefix); thin-walled H-beam - HT (T for Thin English prefix). Hakoreshwa ikimenyetso cy’imiterere ya H-beam: H n’agaciro k’uburebure bw’agaciro ka h x ubugari bw’agaciro ka b x agaciro k’ubunini bw’agaciro ka web t x agaciro k’ubunini bw’agaciro ka t2 kavuzwe. Urugero nka H800x300x14x26, ni ukuvuga, ku burebure bw'igice cya 800mm, ubugari bwa flange bwa 300mm, ubugari bwa web bwa 14mm, ubugari bwa flange bwa 26mm H-beam. Cyangwa hagaragazwa mbere n'ibimenyetso bya HWHM na HN icyiciro cya H-beam, hagakurikiraho "uburebure (mm) x ubugari (mm)", nka HW300x300, ni ukuvuga uburebure bw'igice cya 300mm, ubugari bwa flange bwa 300mm h-beam.
6. Umurabyo wa T
Umuraba wa T (Ishusho) ugabanyijemo ibyiciro bitatu, kode ni iyi ikurikira: igice cy'umuraba wa T-beam - TW (W ku mutwe wa Wide English); mu gice cy'umuraba wa T-beam - TM (M ku mutwe wa Middle English); igice cy'umuraba wa T-beam - TN (N ku mutwe wa Narrow English). Umuraba wa T-beam ukurikije umuraba wa H ujyanye n'uwo hagati mu muyoboro ungana ugabanyijemo kabiri. Ibisobanuro bya T-beam byanditseho: T n'uburebure agaciro ka h x ubugari agaciro ka b x ubunini bwa web agaciro ka t x ubunini bwa flange agaciro ka t. Nka T248x199x9x14, ni ukuvuga, ku burebure bwa 248mm, ubugari bw'ibaba bwa 199mm, ubunini bwa web bwa 9mm, ubunini bwa flange bwa 14mm T-beam. Ishobora kandi gukoreshwa hamwe n'umuraba wa H usa n'aho ugaragara, nka TN225x200, ni ukuvuga uburebure bw'igice bwa 225mm, ubugari bw'umuraba wa 200mm, igice cya T-beam.

7.umuyoboro w'icyuma wubatswe
Umuyoboro w'icyuma nk'igice cy'ingenzi cy'ibikoresho by'icyuma n'ibyuma, bitewe n'uburyo ukorwamo n'imiterere y'umuyoboro ukoreshwa mu bintu bitandukanye bibi kandi bigabanyijemo ibiceumuyoboro w'icyuma udakora(ibisa n'ibibi) naumuyoboro w'icyuma ushongeshejwe(isahani, hamwe n'ibibi) ibyiciro bibiri, reba Ishusho.
Imiterere y'icyuma ikunze gukoreshwa mu muyoboro w'icyuma ushyushye udafite umugozi n'umuyoboro w'icyuma uvanze, umuyoboro w'icyuma uvanze uvanze uva mu gice cy'icyuma, hakurikijwe ingano y'umurambararo w'umuyoboro, kandi ugabanyijemo ubwoko bubiri bwo gusudira imigozi igororotse n'umuyoboro wo gusudira uzungurutse.Umuyoboro w'icyuma wa LSAWIbipimo ngenderwaho by'umurambararo w'inyuma wa mm 32 ~ 152, ubugari bw'urukuta bwa mm 20 ~ 5.5. Ibipimo ngenderwaho by'igihugu by'"umuyoboro w'icyuma wa LSAW" (GB/T13793-2008). Umuyoboro w'icyuma udakora neza ukurikije ibipimo ngenderwaho by'igihugu by'"umuyoboro w'icyuma udakora neza" (GB/T8162-2008), hari ubwoko bubiri bw'umuyoboro ushyushye n'umuyoboro ukururwa ukonje, umuyoboro ukururwa ukonje ugarukira ku murambararo muto w'umuyoboro, umurambararo w'icyuma udakora neza ushyushye wa mm 32 ~ 630, ubugari bw'urukuta bwa mm 25 ~ 75.
Ibisobanuro by'umurambararo wo hanze x ubugari bw'urukuta (mm), nka φ102x5. Umuyoboro w'icyuma uhujwe ugoswe kandi ugasukwa n'icyuma, igiciro ni gito cyane. Ikwirakwizwa ry'agace k'amaso k'umuyoboro w'icyuma ni ryiza, igihe cyo kutagira imbaraga mu mpande zose n'uburebure bw'umuyoboro ni kimwe kandi kinini, bityo imikorere y'imbaraga, cyane cyane iyo igitutu cy'umugongo ari cyiza, n'imiterere yawo ituma udahangana n'umuyaga, imiraba, urubura, ariko igiciro kirahenze cyane kandi imiterere yo guhuza ikunze kuba ingorabahizi.
