LIGHTWEIGHT BODY FOR A HOLLOW CONCRETE SLAB, AND UNIT PANEL FOR A HOLLOW CONCRETE SLAB USING SAME

WIPO Patent Application WO/2010/018989

A2

The present invention relates to a unit panel for a hollow concrete slab integrally assembled with a lightweight body. The unit panel for a hollow concrete slab includes a lower wire mesh, a plurality of lightweight bodies disposed on the lower wire mesh, an upper wire mesh disposed on the lightweight bodies, and a truss member fixed to the upper wire mesh and the lower wire mesh. The lower wire mesh, the lightweight bodies, the upper wire mesh, and the truss member are assembled in advance in a factory. Each of the lightweight bodies includes a semispherical upper lightweight body, a semispherical lower lightweight body facing the upper lightweight body, and a cylindrical height adjusting portion interposed between the upper lightweight body and the lower lightweight body. The upper and the lower lightweight bodies further have a plurality of grooves and double grooves. Whereby, the cost and time required for the arrangement and assembly of the lightweight bodies in the field can be reduced to shorten the overall construction period, minimize defects in the field, and reduce costs. The present invention can be applied even in the case of a varying thickness of the slab, thereby reducing costs. The present invention has grooves for the easy fixation of reinforcing rods or wire meshes for preventing the buoyancy of the lightweight bodies, and reduces costs by reducing concrete consumption. Further, the lightweight body of the present invention has an increased volume to reduce the consumption of concrete, and the height adjusting portion of the present invention adjusts the height of the lightweight body even when the lightweight body has a large volume, costs can be reduced as the present invention can be applied in the case of a varying thickness of the slab without the need for manufacturing lightweight bodies in a variety of sizes.
