Kev loj hlob keeb kwm ntawm lub teeb steel villa nyob hauv tsev thiab txawv teb chaws

Tsis ntev los no, hauv kev lag luam vaj tsev tau tawg ib qho tawg ntawm "lub teeb hlau villa cua", qhov tshiab no tau ua rau ntau tus neeg mloog. Lub teeb lub tsev steel pom nyob hauv Suav teb thaum xyoo 1990s. Niaj hnub no, thev naus laus zis thev naus laus zis ntawm cov qauv hlau tsim yog qhov paub tab, txhawb nqa los ntawm lub teb chaws, thiab nws tau nkag mus rau cov pej xeem lub zeem muag. Yog li teb chaws vam meej tsim kho lub tsev no? Vim tias kev ntxiv dag zog ntawm ib puag ncig kev paub thiab tsis txaus cov ntoo thiab lwm yam, ntau lub teb chaws xws li Asmeskas, Nyiv, Britain, Australia tau nquag txhawb nqa daim ntawv thov thiab kev txhim kho ntawm cov hluav taws teeb muaj zog qis tsev qis hlau.

Txij li thaum xyoo 1960, Australia tau tso lub tswv yim ntawm "kev txhim kho kom sai ntawm lub tsev prefabricated", tab sis vim tias kev lag luam tsis loj, nws tsis tau muaj kev txhim kho zoo. Xyoo 1987, lub zog muaj zog txias-tsim thin-walled steel qauv tshwm sim, thiab kev sib koom tes tshwj xeeb ntawm Australia thiab New Zealand, raws li / nzs4600 txias-tsim cov txheej txheem hlau, tau tshaj tawm thiab siv rau xyoo 1996. Hom hlau no muaj peev xwm loj cov kabmob. Muab piv nrog tib cov kabmob muaj peev xwm ntawm cov ntoo, nws tsuas yog 1/3 ntawm qhov hnyav ntawm ntoo. Qhov saum npoo yog galvanized. Nyob rau hauv qhov xwm txheej ntawm tsis muaj kev txhim kho, lub durability tuaj yeem ncav cuag 75 xyoo.

Lub teeb steel tsev tab tom loj hlob sai tshaj hauv Asmeskas. Xyoo 1965 cov tsev tub ntxhais hluas steel txua tsuas yog 15% ntawm kev ua lag luam hauv Tebchaws Asmeskas; Hauv xyoo 1990 nws tau nce mus rau 53 feem pua, thaum xyoo 1993 nws tau nce mus rau 68 rau ib xees thiab thaum 2000 nws tau nce mus rau 75 rau ib xees. Kev ua tiav, qhov tseeb, tshwj xeeb, kev lag luam thiab kev lag luam ntawm cov khoom lag luam hauv cheeb tsam thiab cheeb tsam yuav luag yog 100%. Kev cog lus qiv ntawm ntau yam kev tsim ua tshuab, khoom siv thiab khoom siv tau tsim tau zoo heev, thiab kev lag luam qib tau ncav cuag 40%.

Nyob rau hauv xyoo tas los, lub teeb steel keel system lub tsev nrog txias-tsim steel yog txoj kev tsim kho tshiab uas tab tom txhim kho sai hauv Tebchaws Europe thiab Asmeskas. Nws yog dav siv hauv vaj tsev, tsev, zoo nkauj chaw, chaw ua haujlwm, tsev kawm ntawv, tsev kho mob, tsev coj mus muag thiab lwm yam. Hauv tebchaws Australia, kwv yees li $ 600 lab ntawm cov teeb hluav taws xob steel keel cov tsev raug tsim tsa nyob rau txhua xyoo 120,000, uas yog kwv yees li 24% ntawm tus nqi ntawm txhua qhov lag luam tsim vaj tsev hauv Australia; Hauv Asmeskas cov xov tooj ntawm cov tsev tsim txoj siv no tau dhia los ntawm 55,000 nyob rau nruab nrab xyoo 1990 txog 325,000 hauv xyoo 2000. Tam sim no, hom teeb vaj tsev steel hlau tau dhau los ua lub ntsiab qauv kev tsim qauv hauv cov tebchaws tsim.
