I-STEEL COMPOSITE HOLLOW FLOOR PLATE HAVING VERTICAL JOINT AND CONNECTION METHOD THEREOF

摘要

PURPOSE: A connection method for an I-steel composite hollow floor plate having a vertical joint is provided to reduce a weight of a floor plate remarkably by reducing a weight of concrete, to apply for maintenance of the floor plate effectively, to construct a slim structure, to shorten a period of work remarkably and to simplify a construction by precasting a product. CONSTITUTION: The connection method for the I-steel composite hollow floor plate having the vertical joint comprises the steps of: installing a base plate(1) composed of a steel plate to use as a floor form possibly; arranging many I-steels(10) provided with a through hole on the base plate(1) instead of a main reinforcement bar; arranging a hollow pipe(20) through the through hole to cross the I-steel(10); arranging lower distributing bars(21) to the through hole and arranging upper distributing bars(22) on an upper flange of the I-steel(10); placing looped connecting bars(50) between the I-steels(10) to make a looped part of the looped connecting bar(50) projected toward the lateral side of the floor plate and to make the other end of the looped connecting bar(50) buried under concrete; constructing an I-steel composite hollow floor plate by placing concrete on the I-steel(10), the hollow pipe(20) and the upper, lower distributing bars(21,22) arranged on the base plate(1); arranging I-steel composite hollow floor plates horizontally to make the looped part of the looped connecting bar(50) overlapped; arranging joint distributing bars(23) vertically on the looped part of the overlapped looped connecting bar(50); and forming a joint by placing joint concrete to the looped part of the looped connecting bar(50) where the joint distributing bars are arranged.
