FLAT SLAB USING STEEL PIPE CONCRETE COLUMN AND CONSTRUCTION FOR THE SLAB

Japanese Patent JP3802996

B2

PROBLEM TO BE SOLVED: To easily construct a flat slab capable of securely transmitting a vertical load by inserting reinforcements between a steel pipe for a lower floor column and a steel pipe for an upper floor column and placing concrete to form a steel pipe concrete column.
SOLUTION: Reinforcements 11 for a capital 4 are arranged in the head of a steel pipe 5 erected on a reinforced concrete body of a lower floor and column main reinforcememts 7 banded by hoops 6 are inserted therein. Then, a form for the capital 4 is assembled and concrete is placed in the form and the steel pipe 5 to form a lower floor column 3 as a steel pipe concrete column 2 provided with the capital 4. Further, the steel pipe 5 of the upper floor column 10 is erected in the column main reinforcements 7 projected from the lower floor column 3 and a form for the slab 9 is assembled, and slab reinforcements are arranged and concrete is placed to construct the flat slab 1. Thereafter, concrete is likewise placed in the steel pipe 5 of the upper floor column 10. In this way, the flat slab 1 through which the load of the upper floor column 10 and the slab 9 can be securely transmitted to the lower floor column 3 can be easily constructed.
