Jimyeo it before folding for storage or transportation is made easy to install, expand when you want to install for easy installation can help with the addition and the construction is finishing layer on the top surface to allow sufficient space between the building slabs and finishing layer is made, possibly folded superstructure is connected fixed to each other; Provides interlayer Noise folding support device for containing; lower structure which is provided makes it possible to adjust the upper structure from the slab to a predetermined height so that additional space for the vibration and noise canceling and between the slab formed in the lower portion of the upper structure .
Accordingly it may be made to the logistics convenient, not only can improve economic efficiency and reduce overall construction time to fundamentally block that vibration or noise transmitted to the lower layer has the effect that you can live a comfortable life in the downstairs.
