HOLLOW CORE DECK PLATE WITH LIGHT WEIGHT BODY

摘要

The present invention relates to a hollow deck plate having lightweight bodies capable of obtaining the integrated movement of rebars and concrete by installing lightweight bodies and the rebars not to be met each other and preventing the strength degradation of a hollow slab wherein the concrete is completely cured. The hollow deck plate comprises: a floor plate (300); truss girders (200) coupled to an upper part of the floor plate (300) at a predetermined interval; and lightweight bodies (100) arranged in spaces between the truss girders (200). The truss girder (200) comprises: an upper rebar (210); lattice members (220) gradually widened downwards from a top, of which inner side comes in contact with and is welded to both sides of the upper rebar (210); and lower rebars (230) coming in contact with and welded to an outer bottom of each lattice member (220). The lightweight body (100) comprises: a lower body (110) in a hollow container shape; an upper body (120) in a hollow lid shape coupled to an upper part of the lower body (110) to form the lightweight body (100); and connection protrusion parts (111) horizontally protruding from a front and a rear surface of the lower body (110). The whole height of the upper body (120) is manufactured in various sizes to allow selection of the size in accordance with the thickness of a slab and the connection protrusion parts of the lightweight bodies close to each other come in contact with each other.
