摘　　要：装配式叠合楼板是由预制混凝土底板和现浇钢筋混凝土层叠合而成的装配整体式楼板。对比分析了装配式叠合楼板、钢质楼承板、纤维水泥板楼承板、细石混凝土免拆钢筋桁架楼承板的生产工艺与性能特点。重点分析了采用高贝利特硫铝酸盐水泥制作的细石混凝土免拆钢筋桁架楼承板的工艺特点及性能。高贝利特硫铝酸盐水泥细石混凝土底板吊装速度快、脱模时间短、低温免蒸养、免拆模;底板密度较小、收缩变形量小、抗压强度高、吸水率小、跨度大。The assembled laminated floor slab is an assembled monolithic floor slab made of prefabricated concrete sub-slabs and cast-in-place reinforced concrete layers laminated together.The production process and performance characteristics of assembled laminated floor slabs,steel floor joist slabs,fibre cement board floor joist slabs,and fine stone concrete non-demolition reinforced truss floor joist slabs are comparatively analyzed.The analysis focuses on the process characteristics and performance of the fine stone concrete non-demolition steel truss floor joist bearing plate made with high Bailey's sulphated aluminate cement.High Bailey's sulphated aluminate cement fine stone concrete base plate has fast hoisting speed,short demoulding time,low-temperature free steaming and demolition-free moulding.The base plate has smaller density,small shrinkage and deformation,high compressive strength,small water absorption rate,and large span.
