Chengdu Art Museum Space Ncej
Cov txheej txheem no yog tshwj xeeb-zoo li tus steel qauv qhov chaw pob txha / raw khoom Q235B welded yeeb nkab / tag nrho qhov siab 45 meters / tag nrho ncua 115 meters / tag nrho ntev 1577 meters.
1. Cov hlau siv nyob rau hauv steel qauv qhov chaw ncej yuav tsum muaj tensile lub zog, elongation, yield zog thiab leej faj thiab phosphorus cov ntsiab lus, thiab yuav tsum muaj qhov tsim nyog guarantee ntawm cov ntsiab lus carbon.
2. Tag nrho cov steels yog welded structural steels, thiab yuav tsum tau mus rau tensile xeem, dabtsi yog khoov xeem, thiab V-notch cuam tshuam kev xeem raws li tus tsim yuav tsum tau, thiab kuj yuav tsum tau raws li qhov yuav tsum tau ntawm weldability.
3. Tag nrho cov khoom siv hlau xws li kab teeb thiab kab yog ua los ntawm Q355B steel, saib cov duab kos kom paub meej.Cov qauv zoo ntawm cov khoom yuav tsum ua tau raws li cov qauv hauv lub tebchaws tam sim no "Low Alloy High Strength Structural Steel" (GB/T 1591-2018).Lub zog tensile, elongation, yield point, txias dabtsi yog khoov kuaj thiab cuam tshuam toughness ntawm cov khoom yuav tsum tau guaranteed kom tsim nyog, thiab cov ntsiab lus ntawm leej faj, phosphorus thiab carbon yuav tsum tau guaranteed kom tau raws li qhov yuav tsum tau.
4. Thaum lub sij hawm tsim seismic, cov hlau yuav tsum ua raws li cov cai hauv qab no:
Qhov piv ntawm qhov ntsuas tus nqi ntawm lub zog tawm los ntawm cov hlau rau qhov ntsuas tus nqi ntawm lub zog tensile yuav tsum tsis txhob ntau tshaj 0.85;
Cov hlau yuav tsum muaj cov kauj ruam pom tseeb, thiab qhov elongation yuav tsum tsis pub tsawg tshaj 20%;
Cov hlau yuav tsum muaj qhov zoo weldability thiab lees txais kev cuam tshuam toughness.
5. Cov khoom siv vuam,
Cov khoom siv vuam sib txuas yuav tsum sib phim nrog lub hauv paus hlau.Thaum ob qib steel sib txawv yog welded, cov electrode lossis hlau uas phim cov qib qis zog steel yog siv.Welded kev twb kev txuas nrog dynamic load ncaj qha los yog ib qho tseem ceeb tuab phaj vuam yuav tsum siv tsawg-hydrogen electrodes, xws li E4315, E4316, E5015, E5016 thiab lwm yam qauv.
