The invention relates to a multifunctional brick board composite hollow wall, which comprises two wall panels. The wall is characterized in that: a brick built screen body is arranged between the two wall panels; the brick built screen body comprises continuous obliquely built bricks/blocks which have opposite tilt directions and a mortar combined poles which are arranged on an end-to-end joint parts of adjacent obliquely built bricks/blocks; and one side of the mortar combined pole tightly clings to the inner walls of the wall panels and a hollow pole of a triangular cross section is provided between the side faces of the two adjacent obliquely built bricks/blocks and the inner walls of the wall panels. The multifunctional brick board composite hollow wall has the following advantages that: the stability is greatly improved when compared with that of an empty brick wall; due to the fact that the bricks are laterally built, the bending resistance is increased so that the intensity of a built body is effectively improved; the requirement on the target that the external wall saves 65 percent of energy can be met; and the dosage of the mortar is decreased, the quality is improved andthe state of strong bricks and weak mortar of a conventional brick built body is changed.
