PURPOSE: To eliminate the field arrangement of a hoop reinforcement, rationalize field work, increase the degree of freedom of construction procedures and use lap joints for joining the lower end reinforcements of a PC beam by forming an SRC-structure steel frame in a through-beam structure and using band plates fox junction panels.
CONSTITUTION: Column steel frames 15 are respectively joined to the upper and lower flanges 12a, 12b of a joint portion 10 formed by integrating in a cross state steel frames 12 which consist of the upper and lower flanges 12a, 12b and webs 12c. To the end faces of the steel frame 12 at the joint portion 10, beam steel frames 23 of a beam 22 are joined, where band plates 14 approximately L-shaped are provided and joined between the webs 12c of the respective steel frames 12 in horizontal in such a manner that the crossings of the joint portion 10 are encircled. Also, the lower end reinforcements 19 of a PC beam 22 are joined together via lap joints 25.
