摘　　要：将废旧泡沫塑料加工成方形块体,在双向板中性轴部位非连续填充该块体,替换掉普通混凝土形成新型双向填充板,具有节省材料、降低楼板自重、提高保温隔热及隔声性能的优点。通过对该新型双向填充板进行现场加载试验和其力学性能分析,得到了钢筋和混凝土的荷载-应变曲线,试验结果分析可知,在与相同尺寸的普通混凝土板相比,在配筋相同的情况下,该新型双向填充板承载力并没有降低,力学性能仍能满足规范对楼板的要求。Disused expanded polystyrene plastic is processed into square blocks which are filled in the neutral axis location of cast-in-situ slabs. These blocks replace concrete to construct a new kind of slab.According/y, concrete is saved, weight is decreased and its function such as warm keeping, heat insulation and acoustic insulation are improved.Based on the practical experiment and mechanical analysis;the load-strain curves of steel and concrete under dead load is obtained.According to the experimental results, it is found that the bearing capacity of the slab is not lower compared with the normal concrete slab with equivalent size and steel.The mechanical properties of the slab filled with disused expanded polystyrene plastic blocks can fulfil the requirements of the correlative codes.
