The vertically bent portion and the inwardly bent portion are inserted to the bottom surface or the lateral surface of the mortar portion to reinforce the engagement between the mortar portion and the lower plate. The flat plate is provided with at least one of embossed recessed portion, a punched recessed portion, a fixing portion, and a metal lath to further reinforce the engagement between the mortar portion and the bottom surface, thereby preventing the mortar portion from being peeled from the lower plate. |
