Taw qhia
Expanded Polystyrene (EPS) lub tsev modules, feem ntau siv hauv Insulated Concrete Form (ICF) systems, sawv cev rau kev nce qib tseem ceeb hauv kev tsim kho tshuab. Cov tshuab no muaj lub teeb yuag, ntxaib - cov ntawv EPS phab ntsa uas kaw ua ke - zoo ib yam li cov menyuam yaus lub tsev thaiv - los tsim formwork rau structural pob zeb phab ntsa. Tsis zoo li cov qauv ua qauv, EPS modules tseem nyob hauv qhov chaw tom qab kev tso chaw ua vaj tse, ua haujlwm ruaj khov thermal rwb thaiv tsev.
ICF kev tsim kho muaj ntau yam zoo: txo lub sijhawm tsim kho, sib raug zoo nrog ntau yam kev ua tiav, kab tsis kam, lub zog, txo suab nrov, thiab txuag hluav taws xob tseem ceeb. ICF cov tsev yog cua- pov thawj, lub zog- ua haujlwm tau zoo, thiab muaj zog ntau dua li ntoo- cov vaj tsev. Txawm li cas los xij, txawm tias cov txiaj ntsig zoo li no, cov thev naus laus zis nthuav tawm ntau qhov kev sib tw ntawm cov khoom siv, cov txheej txheem tsim kho, lub tsev physics, thiab kev txiav txim siab tsim.
Khoom siv & kev ua tau zoo
Kev Sib Tw: Tsis muaj kev siv tshuab tsis txaus thiab deformation thaum muab pob zeb
EPS nyob rau hauv qhov tseeb yog qhov tsawg- cov khoom ua npuas ncauj uas muaj peev xwm tsim tau tsawg. Thaum cov pob zeb tau nchuav rau hauv cov ntawv EPS, lub siab hydrostatic tuaj yeem ua rau bulging, deformation, lossis txawm tias daim ntawv tsis ua haujlwm. Module phab ntsa yog cov mos mos ua ntej pob zeb pouring, uas tuaj yeem yooj yim ua rau cov phab ntsa tsis zoo.
Mitigation Strategies:
Xaiv lub siab - qhov ceev EPS modules (Ntau dua lossis sib npaug li 20 kg / m³) nrog kev ua kom muaj zog compressive (Ntau dua lossis sib npaug rau 100 kPa ntawm 10% strain)
