2. Usoro mgbazi
2.1 Nrụrụ akụkụ nke efere flange
Gbazie nrụrụ nke ogidi igwe nwere ụdị H, ihie na akụkụ nkwado.Na flange efere (n'èzí alignment weld) longitudinal linear kpo oku (okpomọkụ okpomọkụ na-achịkwa n'okpuru 650 degrees), ntị ka kpo oku nso adịghị gafere nso nke na-achịkwa abụọ ịgbado ọkụ ụkwụ, otú adịghị eji mmiri jụrụ.Mgbe ị na-ekpo ọkụ n'ahịrị, ṅaa ntị na: (1) ekwesịghị ikpo ọkụ ugboro ugboro n'otu ọnọdụ ahụ;(2) Adịla mmiri n'oge okpomọkụ.
2.2 Ntugharị elu na mgbada dị ala na ngbanwe ngbanwe
(1) N'elu efere flange, na-eche ihu weld longitudinal, site na etiti ruo na nsọtụ abụọ nke ikpo ọkụ linear, ị nwere ike dozie nrụrụ na-ehulata.Iji zere ịgbagọ na ngbanwe ngbanwe, a na-eme eriri ọkụ abụọ ahụ n'otu oge.Enwere ike iji mmezi ọnọdụ okpomọkụ dị ala ma ọ bụ mgbazi okpomọkụ.Usoro a na-enyere aka ibelata nrụgide na weld, ma usoro a nwere nnukwu mpụta n'akụkụ n'otu oge ahụ ogologo oge shrinkage, nke siri ike ịmụta.
(2) Linear kpo oku na flange efere na triangular kpo oku na webụ.Jiri usoro a iji dozie nrụrụ nke ogidi, ogwe, ihe nkwado, mmetụta ahụ dị ịrịba ama, a na-ewere obosara ikpo ọkụ ahịrị kwụ ọtọ 20-90mm, ọkpụrụkpụ efere ahụ bụ otu elekere, obosara kpo oku kwesịrị ịdị warara, na usoro kpo oku kwesịrị ịdị warara. a ga-agbatị site na etiti obosara ruo n'akụkụ abụọ.Linear kpo oku kacha mma na-arụ ọrụ mmadụ abụọ n'otu oge ahụ, na-ekpo ọkụ na obosara nke triangle triangle ekwesịghị gafere 2 ugboro ọkpụrụkpụ nke efere, na ala nke triangle hà nhata linear kpo oku obosara nke kwekọrọ ekwekọ nku. efere.Triangle kpo oku na-amalite n'elu wee gbasaa site na etiti ruo n'akụkụ, na-ekpo ọkụ oyi akwa site na oyi akwa ruo ala nke triangle.Okpomọkụ ekwesịghị ịdị elu mgbe ị na-ekpo ọkụ na weebụ, ma ọ bụghị ya, ọ ga-eme ka ịda mbà n'obi na-esiwanye ike ịrụzi.
Mara: Usoro kpo oku triangle dị n'elu dịkwa na mgbazi akụkụ nke akụkụ ahụ.Mgbe ị na-ekpo ọkụ, a ga-eji mmezi okpomọkụ nke ọkara mee ihe, na ịgbara mmiri kwesịrị ịdị ntakịrị.
(3) Nrụrụ ebili mmiri nke kọlụm, bems na webụ nkwado
Iji dozie nrụrụ nke ebili mmiri, anyị ga-ebu ụzọ chọta ọnụ ọgụgụ dị elu wee jiri usoro kpo oku dot jiri hama aka dozie.The dayameta nke kpo oku ntụpọ bụ n'ozuzu 50 ~ 90mm, mgbe ọkpụrụkpụ nke ígwè efere ma ọ bụ wavy ebe dị ukwuu, na dayameta kwesịrị ka gbasaa, nke nwere ike pịa d = (4δ + 10) mm (d bụ dayameta). nke ebe kpo oku; δ bụ efere efere) gbakọọ iji gbakọọ uru nke kpo oku.Ihe grille na-agagharị n'okirikiri site na elu nke ebili mmiri ma na-edozi ya na ọkara okpomọkụ.Mgbe okpomọkụ ahụ ruru ogo 600 ruo 700, a na-etinye hammer na nsọtụ ebe a na-ekpo ọkụ, mgbe ahụ, a na-eji sledgehammer kụnye hama ahụ, nke mere na ígwè dị na mpaghara kpo oku na-agbaze, na nkwekọrịta jụrụ oyi na-adaba.Ekwesịrị izere nrụgide nrụrụ aka dị ukwuu n'oge mgbazi.Mgbe emezichara otu ntụpọ, a na-ekpo ọkụ nke abụọ crest, dị ka n'elu.Iji mee ka ọnụego jụrụ oyi dị ngwa, igwe Q235 nwere ike mee ka mmiri dị jụụ.Usoro mgbazi a bụ nke usoro kpo oku ntụpọ, na nkesa ebe kpo oku nwere ike ịbụ ntụpọ plum ma ọ bụ yinye nwere nnukwu ntụpọ.Kpachara anya ka ị ghara ịgafe ogo 750.
Usoro mmezi maka welds fillet
Fillet welds
Nkebi 5.23 nke mbipụta 2015 nke AWS D1.1 na-ekwu maka ndokwa gbasara profaịlụ welded na-anabata na nke anabataghị.Mgbe nha nke weld fillet buru ibu n'ihi nleghara anya, a ga-aghọtahie ihe ngosi profaịlụ ịgbado ọkụ nke edepụtara na ngalaba 5.23.Dị ka American Steel Structure Association si kwuo, na-eche na oke weld metal adịghị egbochi iji njedebe nke onye òtù ahụ, na-enweghị mgbazi fillet weld, ọ nwere ike ime ka akụkụ angular nke fillet weld (ma n'otu akụkụ ma ọ bụ n'akụkụ abụọ). ) ka ibu ibu.Ịgbalị iwepụ ígwè weld ngafe akọwara n'elu nwere ike ịkpata mbelata, nrụrụ na/ma ọ bụ mgbawa nke weld.Ijikwa ọdịdị nke weld fillet ga-agbaso ihe ndị dị mkpa e depụtara na Nkebi 5.23.1 nke mbipụta 2015 nke AWS D1.1.
