PURPOSE: To provide an easy brick laying method for even a Sunday carpenter to do.

CONSTITUTION: Brick layers, on which bored bricks with a middle hole 1 and side holes 2 and 3 are placed in two directions, are stacked in such a fashion that the bricks do not meet well at their joints 5 by half size for every layer. There is provided a single socket joint board 8 which is located on a horizontal surface and projects a middle socket in the central part while there is provided a twin socket joint board 14 which is located on a horizontal surface and linear in the front edge and projects high sockets 10 and 11 on both sides and low sockes 12 and 13 on the rear of the high sockets. The single socket joint boards 8 are inserted backwards on the rear edge between the brick layers is such a fashion that the middle socket 7 may fit into the middle hole 1 while the twin socket joint boars 14 are inserted with their front edge forward in such a fashion that the high sockets 10 and 11 may extend over the side holes 2 and 3 of the adjacent bricks 4 and be fitted in inversely to the middle socket, thereby fitting both the single socket joint boards 8 and the twin socket join boards 14 alternately.
