Kev ua tau zoo thiab kev ua haujlwm ntawm steel rebar

Steel reinforcement yog ib qho kev siv cov khoom siv hauv tsev, feem ntau yog ua los ntawm cov hlau muaj zog. Raws li lawv daim ntawv thiab kev ua haujlwm, steel tuav tau muab faib ua pawg hauv qab no:

1. Ordinary steel bars: tseem hu ua low-carbon steel bars, muaj siab plasticity thiab ductility, thiab yog cov feem ntau siv hom tsev steel tuav.

2. High tensile steel bars: tseem hu ua high-strength steel tuav, muaj zog tensile siab thiab zoo ductility.

3. Kev tsim cov hlau tuav prestressed: siv los tsim cov pob zeb prestressed nrog lub zog tensile siab thiab ductility, uas tuaj yeem ua tiav thiab prestressed los txhim kho lawv lub peev xwm thauj khoom.

4. Twisted steel tuav: muaj ib qho kev toughness thiab ductility, thiab tau ua tiav rau hauv longitudinal threaded cov ntaub ntawv nyob rau saum npoo rau thauj tog rau nkoj nrog pob zeb, txhim kho tensile thiab torsional peev ntawm cov hlau tuav.

Ntxiv rau qhov kev faib tawm saum toj no, muaj ntau yam tshwj xeeb ntawm steel tuav, xws li hnav-resistant steel tuav thiab stainless hlau tuav.

Steel reinforcement yog cov khoom siv tseem ceeb hauv cov qauv pob zeb, uas txhim kho tag nrho cov kabmob muaj peev xwm ntawm cov pob zeb los ntawm kev koom tes nrog cov pob zeb ua rau dais dabtsi yog khoov thiab shear loads. Tshwj xeeb, lub luag haujlwm ntawm steel tuav tuaj yeem raug sau tseg hauv cov hauv qab no:

1. Txhim kho lub zog tensile ntawm pob zeb: Lub zog tensile ntawm pob zeb yog qis dua nws lub zog compressive, thiab steel tuav tuaj yeem muab lub zog tensile ntau dua rau pob zeb, yog li ua kom nws lub zog thiab ruaj khov.

2. Kev tswj cov kab nrib pleb hauv pob zeb: Cov kab nrib pleb tshwm sim los ntawm kev ua vaj tse pob zeb tuaj yeem ua rau muaj kev pheej hmoo ntawm deformation thiab kev puas tsuaj rau cov pob zeb. Qhov sib ntxiv ntawm cov hlau tuav tuaj yeem txwv qhov sib txawv thiab tawg ntawm cov pob zeb, ua kom muaj kev ruaj ntseg ntawm cov qauv.

3. Txhim kho qhov toughness ntawm pob zeb: Lub toughness ntawm pob zeb txiav txim siab nws deformation thiab tsis ua hauj lwm nyob rau hauv dabtsi yog khoov loads, thiab steel tuav yuav muab ntau dua dabtsi yog khoov toughness rau pob zeb, txhim kho lub load-bearing muaj peev xwm thiab kev ruaj ntseg ntawm cov qauv.

4. Txhim kho cov seismic kev ua tau zoo ntawm cov pob zeb: Hauv kev puas tsuaj ntuj xws li av qeeg, cov pob zeb ua kom muaj kev cuam tshuam rau cov khoom siv hluav taws xob tseem ceeb, thiab cov hlau tuav tuaj yeem muab ntau dua seismic tsis kam rau pob zeb, tiv thaiv kev nyab xeeb ntawm cov qauv thiab cov neeg ua haujlwm.

Txij li thaum nws tsim, Shanghai Zhongze Yi Hlau Khoom Co., Ltd. tau cog lus los muab cov ntaub ntawv steel rau cov neeg siv khoom thiab tam sim no tau dhau los ua cov khoom siv hlau hauv ntau yam. Lub tuam txhab muaj cov khoom siv mus sij hawm ntev ntawm cov khoom siv hauv tsev thiab txawv teb chaws, tshwj xeeb hauv cov khoom siv hlau xws li stainless hlau phaj, stainless hlau kav, stainless hlau coils, seamless steel kav, welded kav, thiab lwm yam. Peb muab cov neeg siv khoom ua ntej, muab kev pabcuam tseem ceeb, ua raws li kev txhim kho, thiab tau cog lus los muab cov neeg siv khoom yooj yim thiab ceev cov kev pabcuam. Nrog kev pabcuam zoo, lub tuam txhab tau txais kev txhawb nqa los ntawm ob qho tib si tshiab thiab qub cov neeg siv khoom, thiab tau txais kev ntseeg siab los ntawm ntau tus neeg siv khoom.
