Kev tsim khoom thiab kev siv ntawmprefabricated qhov chawnyob rau hauv Suav teb muaj keeb kwm ze li ntawm 60 xyoo.Hauv 60 xyoo no, kev txhim kho ntawm prefabricated qhov chaw tuaj yeem piav qhia tias yog ib qho snag tom qab lwm qhov.
Txij li thaum xyoo 1950, Tuam Tshoj tau nyob rau lub sijhawm ntawm kev lag luam rov qab thiab thawj Tsib Xyoo Kev Npaj ntawm kev lag luam hauv lub tebchaws.Nyob rau hauv lub hwj chim ntawm kev tsim kho industrialization ntawm yav tas los Soviet Union, Tuam Tshoj txoj kev tsim kho kev lag luam pib coj txoj kev ntawm prefabricated txoj kev loj hlob.Lub ntsiabprefabricated qhov chawNyob rau hauv lub sij hawm no muaj xws li kab, crane kab, ru tsev kab, ru tsev panels, skylight thav duab, thiab lwm yam. Tsuas yog rau lub ru tsev panels, ib co me me crane beams thiab me-span ru tsev trusses, lawv feem ntau yog qhov chaw precasting.Txawm hais tias prefabricated nyob rau hauv factories, lawv feem ntau prefabricated nyob rau hauv ib ntus prefabrication yards tsim rau ntawm qhov chaw.Prefabrication tseem yog ib feem ntawm kev tsim kho kev lag luam.

Tsuas yog rau lub ru tsev panels, ib co me me crane beams thiab me-span ru tsev trusses, lawv feem ntau yog qhov chaw precasting.Txawm hais tias prefabricated nyob rau hauv factories, lawv feem ntau prefabricated nyob rau hauv ib ntus prefabrication yards tsim rau ntawm qhov chaw.Prefabricationtseem yog ib feem ntawm kev tsim kho kev lag luam.

Nyob rau hauv lub lig 1960s thiab thaum ntxov 1970s, nrog rau kev loj hlob ntawm me me thiab nruab nrab-sized prestressed Cheebtsam, ib tug loj tus naj npawb ntawm prefabricated qhov chaw factories tau tshwm sim nyob rau hauv nroog thiab nyob deb nroog.Hollow slab, tiaj tus phaj, purlin thiab dai pobzeb phaj rau pej xeem vaj tse;ru tsev panels, F-shaped daim hlau, trough plates siv nyob rau hauv industrial vaj tse thiab V-shaped folded daim hlau thiab eeb daim hlau siv nyob rau hauv industrial thiab pej xeem vaj tse tau dhau los ua cov khoom tseem ceeb ntawm cov koom haum factories, thiab cov prefabricated qhov chaw kev lag luam tau pib ua zoo.
3. Kauj Ruam Peb
Nyob rau hauv nruab nrab-1970s, nrog rau cov kev tawm tswv yim muaj zog ntawm tsoom fwv departments, ib tug loj tus naj npawb ntawm cov pob zeb loj slab factories thiab thav duab teeb slab factories tau tsim, uas tsim tawm ib tug upsurge ntawm txoj kev loj hlob ntawm prefabricated qhov chaw kev lag luam.Los ntawm nruab nrab-1980s, kaum tawm txhiab tus prefabrication nroj tsuag ntawm ntau qhov sib txawv tau tsim nyob rau hauv nroog thiab nyob deb nroog, thiab txoj kev loj hlob ntawm Tuam Tshoj cov khoom lag luam mus txog qhov siab tshaj plaws.Nyob rau theem no, lub ntsiab hom ntawm prefabricated qhov chaw yog raws li nram no.Cov khoom siv hauv tsev: sab nrauv phab ntsa slab, prestressed tsev slab, prestressed ncig orifice phaj, precast qhob sam thiaj, thiab lwm yam. (raws li qhia nyob rau hauv daim duab 1);
Cov khoom siv hauv tsev: crane beam, prefabricated kem, prestressed ru tsev truss, ru tsev slab, ru tsev beam, thiab lwm yam (raws li qhia nyob rau hauv daim duab 2);
Los ntawm ib qho kev pom zoo, kev tsim cov khoom siv prefabricated hauv Suav teb tau ntsib cov txheej txheem kev loj hlob los ntawm qis mus rau siab, los ntawm cov ntawv qhia feem ntau mus rau kev sib xyaw tshuab, kev sib sau tshuab, thiab tom qab ntawd mus rau kev sib dhos kab ntau lawm nrog qib siab ntawm kev siv tshuab hauv lub hoobkas. .
4. Thawj kauj ruam
Txij li thaum xyoo 1990, cov tuam txhab lag luam tsis muaj txiaj ntsig, feem ntau ntawm cov tuam txhab loj thiab nruab nrab hauv cov nroog tau mus txog qhov tsis muaj kev vam meej, thiab cov khoom me me hauv cov vaj tse hauv pej xeem tau muab txoj hauv kev rau kev tsim cov khoom me me hauv cov zos thiab cov nroog. .Nyob rau tib lub sijhawm, qhov tsis zoo hollow slabs uas tsim los ntawm qee lub nroog cov tuam txhab ua lag luam nyab xeeb kev tsim kho kev lag luam, uas cuam tshuam ntxiv rau cov duab ntawm cov khoom lag luam prefabricated.Txij li thaum pib ntawm 1999, qee lub nroog tau ua tiav kom txwv tsis pub siv precast hollow pem teb thiab siv cov cam khwb cia hauv-situ pob zeb, uas tau cuam tshuam hnyav rau kev lag luam prefabricated, uas tau mus txog qhov tseem ceeb ntawm lub neej thiab tuag.
Nyob rau hauv lub xyoo pua 21st, tib neeg tau pib pom tias cov txheej txheem cast-in-situ tsis muaj tag nrho raws li txoj kev loj hlob ntawm lub sijhawm.Rau kev txhim kho kev tsim kho kev lag luam hauv Suav teb, qhov tsis zoo ntawm cov txheej txheem cast-in-situ yuav pom tseeb.Nyob rau hauv lub ntsej muag ntawm cov teeb meem no, ua ke nrog cov kev vam meej ntawm txawv teb chaws vaj tse industrialization, Tuam Tshoj txoj kev lag luam kev tsim kho tau ib zaug dua tawm ib nthwv dej ntawm "kev tsim kho industrialization" thiab "tsev industrialization", thiab kev loj hlob ntawm prefabricated qhov chaw tau nkag mus rau lub hnub nyoog tshiab.
Nyob rau hauv xyoo tas los no, nyob rau hauv cov kev taw qhia ntawm cov kev cai ntawm tsoom fwv departments, txoj kev loj hlob ntawm kev tsim kho industrialization yog zoo.Qhov no kuj ua rau cov pab pawg, cov tuam txhab, tuam txhab, cov tsev kawm ntawv thiab cov chaw tshawb fawb tshawb fawb tau nce lawv cov kev txaus siab rau kev tshawb fawb ntawm prefabricated qhov chaw.Tom qab xyoo ntawm kev tshawb fawb, lawv kuj tau ua tiav qee qhov txiaj ntsig.
