1. Cov ntsiab lus tseem ceeb tsom xam ntawm steel kem kev tsim kho rau high-rise steel lug
Cov kab hlau yog cov khoom ntsug uas txiav txim siab hauv pem teb qhov siab thiab tag nrho qhov siab ntawm lub tsev, thiab lawv cov kev tsim khoom thiab kev ua haujlwm yuav tsum ua kom tau raws li cov lus qhia thiab cov qauv. Nyob rau tib lub sijhawm, nws yog qhov yuav tsum tau xav txog qhov shrinkage deformation ntawm weld seam thiab compression deformation los ntawm ntsug loads thaum lub sij hawm tig thiab txiav. Yog li ntawd, txoj kev tig thiab txiav ntev ntawm cov kab hlau tsis sib npaug ntawm qhov tsim ntev, txawm tias nws tsuas yog ob peb millimeters, nws tsis tuaj yeem tsis quav ntsej. Tsis tas li ntawd, thaum cov ntoo khaub lig-seem ntawm cov kab hlau sab saud thiab sab qis yog sib npaug tag nrho, lawv tsis raug tso cai sib hloov. Yuav kom txhua lub steel kem yuav tsum tau suav nrog sib txawv thiab ntsia kom raug. Kev vuam ntawm stiffeners nyob rau hauv daim duab plaub los yog square steel kab yuav tsum tau nqa tawm siv nozzle electroslag welding raws li tam sim no specifications, thiab nws tsis raug tso cai siv txoj kev xws li lub thawv phaj drilling los yog qhov ntsaws vuam.
2. Kev txheeb xyuas cov ntsiab lus tseem ceeb ntawm kev tsim kho rau siab siab Steel Structure Frame Beams
Txhawm rau ua kom zoo ductility, kev ntseeg tau ntawm kev sib txuas, thiab hauv pem teb qhov siab qhov tseeb ntawm kev sib txuas ntawm cov ncej ncej thiab steel kem, cantilever beams (cov nyuj luv luv) raug ntsia rau ntawm qhov chaw ntawm lub thav duab beam thaum lub Hoobkas tsim. Kev sib txuas ntawm sab sauv thiab qis flanges ntawm cantilever beam thiab steel kem txais fusion welds, thiab lub vev xaib phaj txais cov welds. Lub nqaj nqaj yog txuas nrog steel kem cantilever beam (luv nyuj ceg), thiab sab sauv thiab sab flanges txuas nrog tag nrho cov nkag welds rau hauv ob sab phlu (tseem ua hauj lwm raws li arc phaj). Lub vev xaib phaj txuas nrog lub zog muaj zog bolts. Vim tias qhov kev sib txawv ntawm qhov kev tsim kho pob zeb ua kom muaj zog ntau dua li qhov yuav tsum tau ua ntawm cov qauv steel, thaum txuas cov kab teeb ci rau cov phab ntsa vaj huam sib luag los yog cov pob zeb txuas ntxiv, lub vev xaib txuas phaj tuaj yeem muaj qhov elliptical, uas yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua. kev xav tau ntawm qhov kev ncua deb ntawm lub qhov npoo. Qhov ntev ntawm cov ncej nqaj tsis sib npaug ntawm qhov ntev tsim, thiab vuam shrinkage deformation yuav tsum tau txiav txim siab. Vuam shrinkage deformation tuaj yeem xam los ntawm cov qauv empirical, thiab tom qab ntawd txheeb xyuas raws li qhov tseeb machining los txiav txim siab qhov ntev ntawm kev tig thiab txiav. Kev sib txuas ntawm cov flanges sab sauv thiab qis ntawm cov kab teeb ci tuaj yeem ua los ntawm kev siv lub zog siab bolts lossis kev sib txuas welded. Tam sim no, feem ntau ntawm lawv txuas nrog kev nkag mus rau tag nrho cov welding nrog lub hauv ob sab phlu. Thaum lub sij hawm tsim kho, weld lub qis flange ua ntej, thiab ces weld lub sab flange. Ib kawg yog qhov chaw welded rau qhov chaw, thiab lwm qhov kawg yog welded. Lub vev xaib phaj txuas nrog lub zog muaj zog bolts. Nws yog ib qho tsim nyog yuav tsum nkag siab tag nrho seb hom kev sib txhuam los yog hom siab-lub zog bolts siv rau hauv kev tsim. Tsim nyog xaiv qhov sib txhuam coefficient ntawm kev sib txhuam hom high-strength bolts. Qhov tseeb ntawm qhov chaw ua haujlwm yog qhov tseem ceeb thaum siv cov pab pawg muaj zog bolt rau kev sib txuas. Tam sim no, template drilling thiab multi axis CNC drilling feem ntau yog siv los ua lub qhov. Tus qub muaj qhov tseeb qis dua, thaum tom kawg muaj qhov tseeb dua, thiab qhov kawg yuav tsum tau muab qhov tseem ceeb rau kev txiav txim siab. Thaum ua cov template qhov, qhov tseeb ntawm lub template yuav tsum tau ua kom tau raws li qhov yuav tsum tau ntawm high-strength bolt los ua ke qhov thiab nyob rau hauv-site installation qhov. Thaum muaj qhov sib txawv hauv zos nyob rau hauv qhov chaw, tsuas yog ib qho reamer raug tso cai siv los laum lub qhov. Nws yog nruj me ntsis txwv tsis pub siv cov roj txiav los nthuav qhov. Yog tias cov roj txiav yog siv los nthuav lub qhov, nws yuav tsum tau kho raws li kev sib tsoo loj.
