A hollow building block is a rectangular block with H-shaped or square-shaped through holes (2). Bolting parts (1) are attached to the rectangular block. The bolting part (1) is attached to the inner wall of each through hole (2) in the H-shaped block and the inner facade of an end rib (4), and is provided with a U-shaped horizontal section or two L-shaped horizontal sections. Or, the bolting part (1) is attached to the inner wall of each through hole (2) in the square-shaped block and the inner facade of the end rib (4), and is provided with an L-shaped horizontal section. The concave facades of the bolting parts (1) are opposite to each other. The outer facade, a wall (3) and the end rib (4) are seamlessly attached to form a stepped shape. The upper end of the bolting part (1) extends out of the through hole (2), and the extension height is smaller than the height of the through hole (2). A wall is built by using the hollow building block. By means of the bolt and hole connecting structure, the built wall has high shear strength and good shock-resistant and anti-crack functions, and is easy to build. |
