fourth step: a self-tapping screw freely penetrates through a hole of the ecological wallboard bottom beam connecting steel plate and the force transmission steel plate and then is connected with the force transmission steel plate on the tenon of the convex foundation beam in a self-tapping way;
fifth step: trowelling grooves at two sides of the ecological wallboard connecting steel plate by using high-performance mortar;
sixth step: installing a layer of floor slab on the convex foundation beam; and painting the wall body by adopting the inner wall decorative paint.
