  • Publication number: 20100287878
    Abstract: A structural composite hybrid beam having an attached fire-resistant coating material, the structural composite hybrid beam including: a cold-formed steel plate beam, which is formed into a form shape having a space where concrete is placed; a concrete slab installed on the cold-formed steel plate beam and that is integrally connected to the concrete; and a flow preventing member protruding from a pair of side plates of the cold-formed steel plate beam, and preventing the fire-resistant coating material sprayed on each of the pair of side plates from flowing down so that the fire-resistant coating material is firmly attached to the each of the pair of side plates. A thickness of the fire-resistant coating material is reduced as the concrete inside the structural composite hybrid beam absorbs heat, and thus construction expenses are reduced. Accordingly, the structural composite hybrid beam has excellent fire-resistant performance unlike a general steel-frame beam.
