The invention provides a direct-through-cold-and-hot-bridge-free multi-row-hole multifunctional hollow brick, which comprises a brick body, wherein the brick body comprises outer and inner hole walls of multi-row holes and sealed hole shape side walls in the multi-row holes, and at least one hole shape for realizing opening holes at one end or two ends is formed in the two ends of each multi-row hole block body for blocking linear cold and hot bridge passages at the two ends of the block body, such as the hole shapes with the codes being C, D, II and III in the multi-row hole block bodies. Besides staggered sealed hole shapes formed by various mutually-staggered ribs in common use, the multi-row hole block bodies are also specially provided with end rib sealed symmetrical long strip prismatic direct through 0-shaped holes, so longest direct-through-cold-and-hot-bridge-free distance holes are formed in the middle sections of the block bodies, matching edge chamfering or angle chamfering is provided, or semicircular open holes are formed in the center of vertical ribs, or concave-convex anti-crack veins are arranged outside the wall, or interlocking mechanisms are arranged at the two ends in a vertical direction, or concave-convex interlocking mechanisms are arranged at top and bottom, and the brick with the advantages that the dry method building can be adopted, the mortar laying is carried out on the wall surface, the weight is light, the intensity is high, anti-seismic and anti-crack functions and the like can be realized, the secondary decoration of pipe laying and wire passing is convenient, the wall surface peeling is prevented, and the service life is as long as that of a building main body is formed.
