Cov yeeb nkab truss yog hais txog ib daim phiaj tsim los ntawm kev sib txuas cov tswv cuab ntawm qhov kawg. Nws yog kev lag luam hauv cov ntaub ntawv thiab muaj lub teeb yuag, ua kom yooj yim rau kev tsim ntau yam qauv nrog cov duab sib txawv kom haum rau ntau lub hom phiaj. Piv txwv li, nws tuaj yeem ua rau hauv kev txhawb nqa yooj yim trusses, arches, thav duab, thiab yees.
Txawm li cas los xij, tsis hais hom twg, txhawm rau ua kom zoo, kev ua haujlwm ntawm Xuzhou yeeb nkab truss yuav tsum tau them sai sai rau cov teeb meem hauv qab no:
1. Thaum welding cov yeeb nkab truss, yuav tsum tau them nyiaj mloog mus rau lub vuam ib ntus. Feem ntau hais lus, qhov nruab nrab ntawm qhov yuav tsum tau welded ua ntej, thiab tom qab ntawd cov txheej txheem vuam yuav tsum tau txuas mus rau cov nodes ntawm ob qho kawg ntawm lub truss kom tsis txhob muaj qhov sib txawv ntawm qhov sib txawv ntawm cov pob ntawm lub truss tshwm sim los ntawm kev sib sau ntawm weld seam shrinkage ntawm ib kawg. Nws tsis pom zoo kom vuam tib lub sijhawm ntawm ob qho kawg ntawm tib lub vev xaib. Cov nodes txuas nrog lub qis chord yuav tsum tau welded ua ntej, thiab tom qab ntawd cov nodes txuas nrog lub qaum chord yuav tsum tau welded.
2. Lub vuam seam loj ntawm cov yeeb nkab truss yuav tsum tau raws li cov thickness los yog vuam ko taw loj yuav tsum tau los ntawm tus tsim, tab sis yuav tsum tsis txhob muaj ntau tshaj vuam qhov siab uas yuav ua rau tseem ceeb welding residual kev nyuaj siab.
3. Thaum lub hauv paus qhov sib txawv ntawm qhov weld zawj ntawm cov yeeb nkab truss yog ntau dua li tus qauv tus nqi ntawm 1.5mm los yog ntau dua, qhov vuam ko taw loj yuav tsum tau nce raws li qhov sib txawv ntawm tus nqi ntau dhau. Txawm li cas los xij, thaum qhov sib txawv ntau dua 5 hli, qhov kawg yuav tsum tau kho los ntawm vuam thiab polishing txoj kev los yog cov hlaws vuam yuav tsum tau welded ntawm lub interface kom txo tau qhov sib txawv weld.
