The Applied Technology And Economic Study Of Laminated Floor Slab

This paper mainly discussed one type of two-way slab floor with prestress in one way. The lower of the superposed floor is precast-prestressed slab, and the upper layer of it is cast-in-situ concrete. Reinforcements set in the precast slab lapped with each other at the side of the slab. In this way, the floor stands loads in two ways. The prestress in precast slab can improve mechanical performance and meet the demands of large room width in many building structures.1. General development situation and application prospect of the two-way laminated slab. The characteristics of two-way laminated slab are constructing rapidly, shorten the construction period, large halls, etc. These advantages will be more important in future, because of the factors such as social development, technology progress, labor cost rise, etc.2. Foundation principle and application technology of two-way laminated slab. Sum up design methods and principle, construction technology and experience of two-way laminated slab technology. It provides reference for the technology application.3. Analysis of technology and economy benefit for two-way laminated slab application. For the sake of analyzing and evaluating the technology and economy benefit of the technology application concretely and precisely, through comparing with commonly used form of floor in steel structures and concrete Structures with column girds in 9m×9m. Demonstrated in this column girds conditions, the two-way laminated slab not only technically feasible, but is also in the economic options.The research provides reference foundation for decision-making of applying composite deck slab technologically and economically.
