According to the modular unit and the modular building method using the same according to the present invention, the modular building constructed using the modular unit is provided with a plurality of buffer members 150 along the square frame structure of the floor frame module 100, so the floor frame module ( 100) It is possible to relieve the vibration in the floor 400 constructed on the floor 400 and the vibration transmitted from the floor 400 to the floor frame module 100 and the load applied to the ground direction of the modular unit 1000. .

In addition, since the earthquake-resistant pillar is installed on one side of the modular building, there is an advantage in that it is possible to build a modular building capable of withstanding the vibration caused by the earthquake by the earthquake-resistant pillar together with the effect of reducing vibration and load by the modular unit.

The description of the presented embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the invention. Thus, the present invention is not intended to be limited to the embodiments presented herein, but is to be construed in the widest scope consistent with the principles and novel features presented herein.
