Expansion type prefavricated house using dome member and its construction method

摘要

The present invention is a structure that is easy to construct by using a self-supporting post and does not install a post in the interior space, thereby increasing space utilization, increasing water permeability, and improving the antibacterial function. In more detail, it relates to a prefabricated house manufactured using high-density foamed polystyrene panels, a foundation frame installed on a foundation having a permeable and antibacterial function, a vertical frame installed on the foundation frame, and installed on the top of the vertical frame It consists of a horizontal frame, a vertical frame and a panel installed on the outer surface of the horizontal frame; By installing the panel using the frame installed on the outside, there is no need for a frame or a pillar supporting the panel in the inner space, so there is an effect of reducing the facility investment cost.
