Abstract:
A steel reinforced concrete (PSRC) column is prefabricated with angle steels at the corners. The column has auxiliary reinforcement bars between the angle steels and tie bars surround the angle steels and auxiliary reinforcement bars. Column capital steel plates are fixed to the structure, outside the angle steels and the auxiliary reinforcement bars. Column capital reinforcing steel plates are diagonally attached inside the PSRC column. A mold is used to fill the column with cement.

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.
Abstract:
Disclosed herein is a built-up type box-shaped steel column for filling concrete therein, that can be formed easily and economically in a built-up scheme by using ┐-beams and steel plates, and a method for manufacturing the same that includes bonding a steel plate at the inner surface of a ┐-shapes during a process of making a built-up type box-shaped steel column, thereby having a good resistance against a lateral pressure of concrete filled in the steel column and preventing the bonded portion from being exposed to the outside to provide a better outer appearance. The built-up type box-shaped steel column for filling concrete therein, includes: a ┐-shapes disposed at each of the four corners of a box-shaped steel column to be formed; and a steel plate disposed between the ┐-shapes adjacent to each other for connecting the ┐-shapes with each other.
