LIGHTWEIGHT RIB TRUSS DECK COMBINING A RIB DECK AND A STEEL WIRE TRUSS, CAPABLE OF BEING MECHANICALLY INTEGRATED WITHOUT WELDING AND PRESSURE WELDING

摘要

PURPOSE: A lightweight rib truss deck combining a rib deck and a steel wire truss is provided to reduce the amount of electricity consumed to manufacture a deck by mechanically integrating the rib deck and the steel wire truss.;CONSTITUTION: A lower permanent mold steel plate is attached to a lattice feet (180) formed on the lower part of a steel wire truss (100) comprising an upper chord (120), a lower chord (140), and a lattice (160) in a lightweight rib truss deck combining a rib deck and the steel wire truss. The lattice feet of the steel wire truss is pushed into a ⊂-shaped groove (370) of a shallow curved rib deck or a deep curved rib deck which is cold-formed into a steel plate (200) of 0.5 mm thicknesses so that the weight of concrete and construction loads are supported without welding.;COPYRIGHT KIPO 2013;[Reference numerals] (a) Steel wire truss; (AA) Deep curved rib truss deck-a cross sectional view; (b) Rib deck; (c) Combination of a steel wire truss and a rib deck
