Concrete Construction Method For Slab And Core Wall Construction The Same Time Using Temporary Columns

摘要

PURPOSE: A method for simultaneously placing concrete on a slab and a core wall using temporary support columns is provided to remarkably reduce construction time and costs by uniting overlapped construction processes. CONSTITUTION: A method for simultaneously placing concrete on a slab and a core wall using temporary support columns is as follows. Multiple steel columns are installed on an N layer of a structure(a). Multiple temporary support columns having the height of a layer are installed on the tops of N layer steel beams to surround a core part on the N layer(b). Multiple N+1 layer steel beams are installed between the tops of the steel columns and the temporary support columns(c). A deck plate is installed on the tops of the N layer steel beams(d). Reinforcing bars for forming a core wall on an N-1 layer and a core wall form are installed(e). Concrete is simultaneously placed on the top of the deck plate and the N-1 layer core wall(f).
