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.
Claims6
A method of constructing a prefabricated steel reinforced concrete (PSRC) column having angle steels and reinforcement bars, the method comprising:
- erecting angle steels on corners of a PSRC column having a quadrangular cross-sectional shape;
- providing auxiliary reinforcement bars between the angle steels;
- surrounding the angle steels and auxiliary reinforcement bars with tie bars horizontally arranged at intervals;
- welding the tie bars around the auxiliary reinforcement bars and the angle steels;
- welding column capital steel plates outside the angle steels and the auxiliary reinforcement bars steel plates being corresponding to height of a beam or a bracket which is attached to the column capital steel plates;
- and
- diagonally attaching column capital reinforcing steel plates inside the PSRC column.
