A hollow brick for quickly building a wall. A brick joint surface (4) is additionally arranged on an upper plane (1) of a hollow brick and extends into through holes of the hollow brick to form a new brick joint surface (4). Continuous upward protrusions (5) are disposed on the inner side of the new brick joint surface (4). Protrusions (3) are disposed on the outer edge of the upper plane (1). Closed grooves are formed between the protrusions on the new brick joint surface (4) and the protrusions (3) on the outer edge of the upper plane. Protrusions (8, 9) matching the grooves formed in the upper plane (1) are disposed on a lower plane (2) of the hollow brick. Quick diversion trenches (6) are disposed on the left side and the right side of the hollow brick. The hollow brick can increase the brick joint area, and the obtained wall has small joints and does not need to be whitewashed. |
