Antidetonation particularly advantageous.In existing hollow building cover system, be related to the packing material in cored slab, mainly have filler rod (and
Claim " tube filler ") and filling box two big class.The section configuration of filler rod is circular or polygon or other composite figure, its section
The ratio of full-size and minimum dimension is general≤and 2, its planar dimension length is general with the ratio of width >=and 2.The section shape of filling box
Shape is rectangle and rectangle corner cut or chamfering, and its flat shape is generally square or rectangle, usual planar dimension
Ratio≤1.5 of length and width.The hollow rate forming cored slab with filling box obviously will exceed the cored slab being formed with filler rod,
But say from mechanics principle, exactly because the sectional area of the relatively small then concrete of filler rod hollow rate is relatively large, so along
The bearing capacity of filler rod direction cored slab is greater than the filling box cored slab of same thickness, especially shear resistance, certainly, hangs down
The straight bearing capacity especially shear resistance in filler rod direction cored slab is weaker.
In reinforced concrete structure skyscraper, framework core wall structure (referred to as " inner core housing ") occupies sizable
Proportion.In the engineering being suitable for cored slab in framework core wall structure, generally use filler rod as packing material, floor is most
