Rakavimbika kutsigira hurongwa ichapa I-danda

I- simbi matanda anoshandiswa nevanodavira anenge ose ano yokuvakira, zvose maindasitiri uye vehurumende. Ane hwakanyatsorwisa yakaderera chaizvo giravhiti, vane yakakwirira mutoro kukwanisa Kutsauka kuti zvinobudirira kunogona kuparadzira mutoro pamusoro anotsigira hurongwa. Ava vakaitwa nokukanda zvigadzirwa zvesimbi (simbi zvigadzirwa, hot-akakungurutsa kaviri-teetä danda) kana nomoto nzira. The sectional vari H-kuumbwa kugadzirwa parusvingo uye flanges maviri perpendicular kwachiri. The echiShinto anogona kuva womukati kutsvetera nokuda okuwedzera amplification. zvigadzirwa kwakadaro akakodzera chisimbiso pamwe amplification miseve (ngaatevedzane C ane gradient 16%) uye nokuda yakaturikwa vanomhanyisa nzira (akatevedzana M ane yakatenuka 12%).

Akakungurutsira kaviri teetä danda anonziwo ane I-danda. The chikuru mafomu aya simbi mishonga - kuvaka uriri, bhiriji zvakagadzirwa, rwoga nzira, nembiru neshongwe. Zvichienderana chinangwa kuvakwa zvivako, steelI I-danda inogona kuchinjwa nokuda workloads zvakasiyana. Zvayakaita, I-zvikamu uye zvakasiyana rusvingo ukobvu pakati echiShinto, ivo echiShinto riri kunobatanidza (zviso zvavo yemukati kufananidza kana kuva pamateru). Kukosha anewo pakusarudza mukugadzira nzira, chinangwa uye michina parameters.

Steel danda kaviri till chinogona kuitwa pane zvaidiwa nehurumende mureza (GOST 8239 - 89, Standard 19425 - 74, GOST 26020 - 83 uye vamwe), uye maererano nokurondedzerwa ari mugadziri. Kana rinopfungaira zvinhu zviri kabhoni simbi STRUCTURAL munhuwo unhu. simbi Chimiro double-teetä danda yaigadzirwa welded simbi STRUCTURAL pasi-chiwanikwa nokuda welded zvivako.

Several vakasiyana mhando I-nematanda pamwe inofambirana zviso echiShinto: Muzvarirwo (B), Mbiru (K), wide- (W), Normal (SB), chimwezve dzinoti (L uye LH). Made kaviri teetä danda riri nezvinodiwa, zvichienderana nechinangwa, ane kureba kubva 4 kusvika 12 M (ichibvumirana mutengi - kusvika 24 m). Zvinogona mukuru (A) kana chakaipa (B) rinopfungaira rwakatwasuka.

Welded simbi I kunemisara wakaumbwa jira simbi mumatanho dzakawanda. First akaumba preform kunodiwa kukura nokuda slicing kubva resimbi, ipapo milled mucheto. Kumorwa Pfekenura Crane vari hwakatamisirwa conveyor bhandi, crimped uye pisa otomatiki kugadzwa. Uyezve, chigadzirwa iri yakanyikwa chaiyo mumusasa kuti kubviswa zvichibvira urema uye kupatsanurwa kuburikidza nenyunje chirimwa nokuda decontamination. Madzidziro welded I-danda vanofanira kusangana zvaidiwa GOST 23118-99 uye GOST 26020-83 (kana ayo parameters dzinokurukurwa pachine pamwe mutengi).

I-matanda dzinoita 30% kuti zviite tichibereka mutoro-hurongwa achienzaniswa inopisa nemakumbo. Rokutanga kutsunga nematanda hukuru yekudyidzana kunoderedza uwandu tsvina. Zvazvakaipira zvinosanganisira I kunemisara munjodzi kuna ngura kana pasina unodzivirira unhani, uye kudiwa michina, pasina izvo havagoni kuiswa.
