In the invention, the same clad bricks are laid in the forward direction, and a positioning convex platform 2 and a longitudinal positioning convex platform 3 are used for realizing transverse and longitudinal self-locking positioning, thereby naturally ensuring the designed thickness and surface smoothness of the wall, forming a combined still air layer 12 which is 9mm to 10mm wide and vertical to the ground, and further blocking heat bridges in vertical bricklaying seams. The cavity of a 28-30mm-wide groove 4 in the horizontal bricklaying seam between two clad bricks is filled with a broken bridge insulation board 10 which is as wide as the groove and has a thickness of 15mm; the broken bridge insulation board 10 is used for sealing a long-strip groove still air layer 11 and the combined still air layer 12 and cutting off the heat bridges in the horizontal bricklaying seams; the exposed part of broken bridge insulation board with a height of 10mm, is used for controlling the coating thickness of anti-crack masonry mortar 13 to be even and uniform. When the self-insulating and energy-saving wall is built, Z-shaped energy-saving building blocks 1 of the upper clad bricks and the lower bricks are laid in a staggered manner so as to cut off heat bridges in vertical bricklaying seams. The structure of the invention, with a reasonable thickness, can satisfy the requirement of saving 50 percent of energy in various regions, or even higher requiremets without an internal or external insulating layer of walls. Simultaneously, the structure is easy to build and the formation of the block shape effectively ensures the thickness of walls and the smoothness of wall surfaces. The thermal insulation function of the still air layer with a thickness of 10mm to 12mm strengthens the heat insulation effect. The insulation boards (28-30mm wide and 15mm thick) between the two clad bricks is capable of cutting off the heat bridge effects.
