PROBLEM TO BE SOLVED: To provide a temporary support joint capable of greatly shortening a construction period while keeping the degree of freedom of slab design high. SOLUTION: This temporary support joint 10 is formed to be usable in a temporary structure which includes a first temporary support 2 and a second temporary support 5 arranged on an upper story. The temporary support joint 10 is provided with a bottom surface which is formed to be connectable to an upper end 2b of the first temporary support 2, and a top surface which is formed to be connectable to a lower end 5a of the second temporary support 5. In the temporary structure, the first and second temporary supports 2 and 5 are vertically connected together, formed to be engageable with reinforcements to be arranged, and integrally held in the slab even after the hardening/coagulation of concrete cast in situ in the state of contact with the reinforcements. The cast-in-place concrete on the upper and lower stories can be simultaneously hardened/coagulated to enable the great shortening of the construction period. COPYRIGHT: (C)2009,JPO&INPIT
