Self-heat insulation wall with cutoff bridges arranged in mortar layers and building method of the self-heat insulation wall

The invention provides a self-heat insulation wall with cutoff bridges arranged in mortar layers and a building method of the self-heat insulation wall. The self-heat insulation wall comprises self-heat insulation building blocks, horizontal mortar joints, vertical mortar joints, horizontal heat-insulation strips, vertical heat-insulation strips and mortar shear connectors, longitudinal grooves are formed in the surfaces of the widths of the self-heat insulation building blocks in the length direction of the building blocks, vertical grooves are formed in the surfaces of the widths of the self-heat insulation building blocks in the height direction of the building blocks, and equally-spaced transverse grooves are formed in the surfaces of the widths of the self-heat insulation building blocks in the length direction of the building blocks; and the horizontal heat-insulation strips are laid in the horizontal mortar joints and the vertical heat-insulation strips are inserted into the vertical mortar joints so t
