CONTINUOUS CONSTRUCTION METHOD FOR PRECAST REINFORCED CONCRETE STRUCTURE AND STEEL-FRAMED STRUCTURE AND PRECAST REINFORCED CONCRETE COLUMN FOR USING THE METHOD

摘要

The present invention relates to a method of continuously constructing a precast reinforced concrete structure and a steel structure, the method including a first step of installing a precast reinforced concrete column having a plurality of main beams exposed at an upper portion thereof; a second step of placing a precast reinforced concrete beam on the precast reinforced concrete column; a third step of installing a lower fixing part on the exposed main beam; a fourth step of placing the upper reinforcing bar in the precast reinforced concrete beam; a fifth step of positioning a fixture of the steel structure on the lower fixing part of the exposed main beam and installing the upper fixing part; a sixth step of placing on-site pouring concrete between the precast reinforced concrete beam and the precast reinforced concrete column; and a seventh step of pouring non-shrinkable mortar into a space between the on-site pouring concrete and the fixture of the steel structure. In the third step, the installation height of the lower fixing part is determined such that the on-site pouring concrete is positioned below the fixture of the steel structure. The fixture of the steel structure is installed on the precast reinforced concrete column before on-site pouring of topping concrete of the precast reinforced concrete beam, and thus the precast reinforced concrete structure and the steel structure can be continuously built by means of the same building process and apparatus.
