新型预应力空心薄板(80mm厚)叠合板工程技术经济分析

Engineering and Cost-Effectiveness Analysis of a New Type of Prestressed Hollow-Thin Slab(80mm Thick) Assembled Laminate

依据80 mm厚预应力空心板结构性能试验结果,分析了该类板作为叠合板底板的可能性;并依据多跨连续叠合板的受力特征,提出了该类板作为叠合板底板时其纵向接头的连接方法.将80 mm厚预应力空心板叠合板、60 mm厚实心底板叠合板、以及传统现浇板的主要经济指标进行对比,指出了该类板作为底板的叠合板在工程造价上的优势.

Based on the structural performance test results of 80 mm thick pre-stressed hollow slab, the possibility of using this kind of slab as the bottom plate of assembled laminate was analyzed. According to the mechanical characteristics of multi-span continuous assembled laminates, the connection method of their longitudinal joints when they were used as the bottom slabs of assembled laminates was put forward. Comparing the main economic indicators of 80 mm thick prestressed hollow slab laminate, 60 mm thick solid floor slab, and traditional cast-in-place slab, the advantages of this type of slab as the bottom plate in engineering cost were pointed out.
