JOINT PART CONSTRUCTION OF REINFORCED CONCRETE POST AND STEEL FRAMED BEAM AND CONSTRUCTION METHOD THEREOF

PURPOSE:To provide rigid joint part construction against, earthquake force by arranging a saddle member in a space between the lower part of girders and vertical part concrete, contacting a plate member with the upper part of the saddle member so as to rigidly join girders, and pin-joining beams squarely with a girder through a bracket. CONSTITUTION:A peripheral wall 1, pillars 2, and posts 3 are formed into RC-structures, and girders 4 and beams 5 are formed into S-structures. Concrete of the vertical part of the post 3 under the girder 4 is placed and mortar 11 is laid thereon, and a saddle member 9 is fixed thereon with anchor bolts 10. Next the girders 4 are butted with each other on the member 9 and piled up, a plate member 12 is contacted with them and fastened with the member 9 by bolts so as to join together the girders 4 in the lengthwise direction. The beams 5 are fitted to the joint part of the girders 4 through a bracket 6 so as to squarely cross the girders 4. Because the beams 5 are pin-joined in the construction for joining the posts and beams, earthquake force is borne by the surrounding RC-structure, but the girders 4 are fastened with each other by bolts through the members 12 so as to be a rigid joint, and have resistance against earthquake force in the direction of the girder 4.
