1.Dab tsi yog qee qhov kev thov tsis ncaj qha?
Raws li cov khoom siv raw, nws tau ua tiav rau hauv cov qauv txheej txheem.
Mainstream xyaum: Niaj hnub nimno standardized lub teeb steel prefabricated lub tsev thav ntawv feem ntau siv "txias-tsim nyias-walled steel." Cov hlau no yog tsim los ntawm galvanized txias- dov steel coils, uas yog txias- khoov rau hauv tej yam ntoo khaub lig-sectional shapes (xws li C-zoo li tus steel, U-zoo li tus steel, thiab square tubing) siv ib tug tshwj xeeb yob txoj kev ntau lawm kab. Tom qab ntawd cov khoom no tau sib sau ua ke rau hauv lub tsev ncej siv bolts.
Xaus: Hauv cov qauv qauv no, txias- dov coils yog cov khoom siv raw khoom, tsis yog "cov khoom siv" siv ncaj qha rau ntawm -site.
Ntawm -qhov chaw tsis yog- qauv tsim (tsis pom zoo, tsis pom zoo)
Nyob rau hauv tsis yog-tus qauv, ib ntus, lossis qis heev- cov xwm txheej nyiaj txiag, theoretically, thicker txias-rolled flat sheets (los ntawm qib txias-rolled coils) tuaj yeem txiav thiab welded rau hauv ib lub thav duab.
Txawm li cas los xij, qhov no nthuav tawm cov teeb meem tseem ceeb:
Tsis muaj kev tiv thaiv corrosion: Ib qho txias txias- cov ntawv dov xeb yooj yim thiab tsis tsim nyog rau qhov chaw tsim kho qhov chaw raug tshav ntuj thiab los nag.
Kev ua haujlwm tsis zoo: Lub zog thiab ruaj khov tsis kam ntawm cov thav duab welded los ntawm cov ntawv tiaj tus yog qis dua li ntawm cov txheej txheem ua kom zoo dua qub (xws li C- zoo li cov hlau).
Kev ua tau zoo yog qhov nyuaj rau lav: Ntawm - qhov chaw vuam deformation yog qhov loj, thiab qhov tseeb thiab lub zog yog qhov nyuaj rau tswj.
2.Dab tsi yog qhov tseem ceeb ntawm cov khoom txias- dov coil (tom qab ua tiav rau hauv txias- ua nyias- cov seem steel)?
C-zoo li tus steel, U- zoo li tus hlau, thiab lwm yam, yog tsim nyob rau hauv cov txheej txheem factories.
3.Dab tsi yog cov ntsiab lus tseem ceeb uas yuav tsum nco ntsoov?
Deg tiv thaiv- kev kho corrosion yog qhov yuav tsum tau ua.
Txias- cov nplooj ntawv steel uas raug ncaj qha rau cov khoom yuav xeb sai sai. Yog tias siv, kub -dip galvanized (GI) lossis galvanized aluminium-zinc (GL) nplooj ntawv yuav tsum tau siv los ua cov khoom siv raw, lossis cov qauv tsim yuav tsum tau ua kom zoo los tiv thaiv- kev kho corrosion.
Cov lej hauv tsev yuav tsum tau ua raws.
Txawm hais tias cov tsev prefabricated yog cov qauv ib ntus, kev nyab xeeb yog qhov tseem ceeb. Lub load-cov kabmob muaj peev xwm ntawm tus ncej (cua load, daus load, kev tsim kho) yuav tsum raug xam los yog ua raws li cov qauv tsim. Kev siv cov ntaub ntawv uas tsis yog - qauv ua rau nws nyuaj rau kev lav phib xaub.
Thickness (khoom siv thickness) yog qhov tseem ceeb.
Lub hauv paus khoom thickness ntawm txias-tsim steel siv nyob rau hauv load- bearing lug feem ntau yog 0.8mm mus rau 2.0mm, nyob ntawm seb qhov ncua sij hawm thiab load. Nyuaj heev (eg,<0.8mm) results in insufficient rigidity and easy deformation; too thick makes cold bending difficult and uneconomical.
Kev ntseeg ntawm kev sib txuas nodes.
Bolt kev twb kev txuas qhov yuav tsum tau prefabricated nyob rau hauv lub Hoobkas los xyuas kom meej qhov tseeb. Randomly drilling ntawm -site yuav ua rau tus ntoo khaub lig tsis muaj zog -section thiab cuam tshuam rau qhov tseeb installation.
4.Dab tsi yog qee cov lus qhia rau kev tsim kho qhov chaw prefabricated vaj tsev?
Peb pom zoo kom yuav cov qauv prefabricated lub tsev los yog lub tsev ntim khoom ncaj qha los ntawm cov kws tsim khoom, siv lub "galvanized txias- ua nyias-walled steel" ncej. Qhov no yog qhov kev nyab xeeb tshaj plaws, ceev tshaj plaws, kev lag luam zoo tshaj plaws, thiab siab tshaj - zoo tshaj. Cov "txias- dov coils" siv ntawm no tau ua kom zoo dua qub (piv txwv li, zoo li tus thiab galvanized profiles).
5.Yog tias koj xav yuav cov ntaub ntawv ntawm koj tus kheej thiab tsim cov qauv, koj xav li cas?
Standard galvanized C-shaped / U-zoo li tus steel profiles uas ua tau raws li qhov yuav tsum tau ua yuav tsum tau muas es tsis txhob txias- dov coils rau kev ua ntxiv. Uncoiling, sib sau, thiab galvanizing cov hlau koj tus kheej tsis yog qhov siv tau lossis tsis raug nqi - zoo rau ib qhov project.
