1、引言轻质墙板是我国近年来发展起来的一种新型的墙体材料。种类比较多,如 GRC 板、陶粒隔墙板、玻璃网增强石膏板、硅镁板、夹芯复合板等,与传统的墙体相比,具有重量轻,保温隔热性能好,施工速度快,且能钉、能锯、能荷,易加工等优点。由于其重量(按面密度)仅为一般轻质砌块重量的1/3～1/4,在高层建筑中,能大大减轻建筑物的重 1, Introduction Lightweight wallboard is a new type of wall material developed in recent years in our country. More types, such as GRC board, ceramsite wall panels, glass reinforced gypsum board, Si-Mg board, sandwich panels, compared with the traditional wall, with light weight, good thermal insulation properties, construction speed Fast, and can nail, saw, charge, easy processing and so on. Because of its weight (according to surface density) is only 1/3 ~ 1/4 of the weight of light-weight block, in high-rise buildings, can greatly reduce the weight of buildings
