EMBEDDING MATERIAL USED IN CAST-IN-PLACE HOLLOW CONCRETE SLAB STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an embedding material 20a suitably used for constructing a cast-in-place hollow concrete slab structure.;SOLUTION: The embedding material 20a used for constructing a cast-in-place hollow concrete slab structure is a foam resin molding having a rectangular shape in plan view, and two or more ridges 22 with a narrow width are formed on the rear face. The ridges are formed in the direction slantly crossing a side. Preferably, the embedding material 20a has at least two through-holes 21 through which a fixing member is passed. The through-holes 21 are formed to penetrate the embedding material 20a from the bottom face of the ridges 22 to the top face of the embedding material 20a.;COPYRIGHT: (C)2010,JPO&INPIT
