我國建筑業中，噪聲污染問題久為人們所詬病。巴中樓承板輕型樓承板的應用使得土建建筑物局面被打破，集環境破壞及污染少、材料回收和利用率高、符合可持續發展要求等眾多優點于一身的樓承板建筑應運而生，逐步被人們所接受。樓承板批發輕型樓承(cheng)板(ban)是近十年來發展(zhan)較(jiao)快的領域(yu)，在(zai)采用輕型樓承(cheng)板(ban)占非住宅建筑投資(zi)的50%以(yi)上(shang)。這種(zhong)結(jie)構(gou)工業化、商品(pin)化程度高，施工快，綜合效益(yi)高，市(shi)場需(xu)求量很大，已引(yin)起結(jie)構(gou)設(she)計(ji)(ji)人員認識。樓承(cheng)板(ban)的研究開發已在(zai)各地試點，是輕鋼發展(zhan)的一個重(zhong)要方(fang)向，目前已經有多(duo)種(zhong)的低層、多(duo)層和高層的設(she)計(ji)(ji)方(fang)案和實例。
