TWO-WAY HOLLOW CORE SLAB AND CONSTRUCTION METHOD THEREOF

摘要

A two-way hollow slab and a construction method thereof are provided to obtain two-way resistant characteristics and to reduce the interlayer noise by limiting unit shaped lightweight forming agents in open cages. A plurality of unit lightweight forming agents(120) are separately installed in the concrete slab. The unit lightweight forming agents are limited in open cages(130). The open cages are extended up to the lower part under the unit lightweight forming agents. The open cage is one of a tripod cage, a spider leg cage, and a box shaped cage. The tripod cage has band shaped plane frames(131), a plurality of leg frames supporting the plane frames, connecting frames(133) connecting the leg frames with an X shape, and fixing pins(134). The unit lightweight forming agents are limited in the open cages by bending lattice iron nets on the unit lightweight forming agents.
