SLIDING SURFACE STRUCTURE OF CAST-IN-PLACE EXTENSION FLOOR SLAB

摘要

<P>PROBLEM TO BE SOLVED: To reduce construction cost by forming a bottom slab and an extension floor slab of cast-in-place concrete. Ž<P>SOLUTION: The bottom slab 3 is formed of cast-in-place concrete. The extension floor slab 4 is formed of a steel plate lower surface structure 41 placed on the bottom slab 3 and a concrete upper surface structure 42 deposited on the lower surface structure 41 at site. The construction cost is reduced by constructing the bottom slab and the extension floor slab having respective reduced coefficients of friction on their sliding surfaces.
