Maeda Master Frame
Technology overview
The Main Frame construction method is a construction method that strengthens the columns and beams of an existing building from the outside of the building. It is suitable for buildings with poles and beams on the outer wall. In addition, since it is reinforced with reinforced concrete elements, it is most effective in reinforced concrete structures and middle and low buildings (up to about 6th floor) with steel reinforced concrete.
For those considering seismic retrofitting, the "mainframe" construction method ensures that construction is completed in a short time while staying at home, and the appearance design upon completion is unique. As a precast (PCa) element is attached to the exterior wall of the building, the cost is lower than the traditional construction method using steel aggregates, and the use of PCa enables a shorter construction time by making it possible to not cast concrete on site.
