FORMED STEEL PLATE CONCRETE BEAM HAVING FIRE-RESISTANT COATING MATERIAL ATTACHING STRUCTURE AND CONSTRUCTION METHOD THEREOF

摘要

PURPOSE: A formed steel plate concrete composite beam having a fireproofing material attaching structure is provided to improve fireproof efficiency and covering efficiency by attaching fireproofing materials between a fireproofing material and a side surface plate. CONSTITUTION: A formed steel plate concrete composite beam having a fireproofing material attaching structure(10) comprises formed steel plate girders(100), a concrete slab(400), and flow prevention members(120). The formed steel plate beams are formed in a mold shape so that concrete(200) is placed in a space. The concrete slab is installed on the upper part of the formed steel plate beams for connecting with the concrete. The flow prevention members protruded from side surfaces(110) of the formed steel plate beams attach fireproofing materials(300) to the side surfaces of the formed steel plate beams by preventing the fireproofing materials from flowing vertically.
