不同预制楼板适用性研究分析及工程案例

Research on Applicability of Different Precast Concrete Slabs and Project Case Studies

目前,工程中常用的预制楼板主要包括SP空心板、双T板以及桁架钢筋混凝土叠合板等。本文首先概括了三种预制楼板的发展进展。然后,从受力性能、构造措施、计算方法等角度梳理总结各种预制板的适用性,并提出了桁架钢筋混凝土单向叠合板选用表。最后,给出了三种预制楼板的实际工程案例。本文得到的关于预制楼板适用性的一些结论,可为装配式建筑工程设计提供参考,帮助解决预制楼板选用问题。

For the moment,the most common precast concrete slabs used in projects include SP prestressed concrete hollow slab,double-T plates,and composite slab by steel bar truss and concrete. This paper firstly briefly introduces the recent development of the three kinds of precast concrete slabs. Then the applicability of different precast concrete slabs was summarized in terms of the stress performance,construction measures,calculation methods,and so on. In addition,the selection table of the composite slab by steel bar truss and concrete was proposed in this paper. Lastly,different projects of the three common precast concrete slabs were given. Some conclusions about the applicability of precast concrete slabs obtained in this paper can be evidential references for the design of prefabricated buildings,and assist in solving the problems in selecting precast concrete.
