Construction method of column-beam frame, precast concrete member and column-beam frame

摘要

PROBLEM TO BE SOLVED: To provide a method for constructing a column-beam frame, a precast concrete member and a column-beam frame, which can be efficiently constructed by using a precast concrete member. SOLUTION: A column-beam frame 12 of a building 10 is constructed by using a plurality of precast concrete (PC) members 20, 30, 40 having joints that can be joined in the vertical direction. The PC member 20 is formed by integrally forming the beam portion 23 and the first pillar portion 21 and the second pillar portion 22 to which the end portions of the beam portion 23 are connected, respectively. The second column portion 22 of the PC member 20 as the second PC column beam member is directly joined onto the first column portion 21 of the PC member 20 as the first PC column beam member, and the first The first column portion 21 of the PC member 20 as the third PC column beam member is directly joined onto the second column portion 22 of the PC member 20 as the PC column beam member. Then, the beam portions 23 of the two PC members 20 that are directly or indirectly joined in the vertical direction are arranged at different height positions. [Selection diagram] Fig. 1
