2. Description of the Related Art In a method of constructing a frame from a column member made of precast concrete or steel pipe concrete and a beam member made of precast concrete, the column member is first erected and then the beam member is suspended. The joints are constructed by placing reinforcements and placing concrete into the joints, but in the past, the beam members were supported after being hung up and stabilized by a crane until they stabilize after being suspended. Therefore, it is difficult to secure the stability during this construction, and the beam members are placed in an unstable state for a long time, which poses a risk of work at the joints and the effective operating rate of the crane. Since it will decrease, the progress of construction will decrease.
