Disclosed is a tetradecahedral building block comprising a number of unit main bodies (1), the structure, shape and volume of each of the number of unit main bodies (1) being the same. The unit main bodies (1) are tetradecahedrons with six square faces (8) and eight hexagonal faces (9), wherein the six square faces (8) are equally divided into three groups, the two square faces (8) in the same group are parallel, the eight hexagonal faces (9) are equally divided into four groups, the two hexagonal faces (9) in the same group are parallel, two or more unit main bodies (1) are plugged together and/or fixedly connected to form a group. A post (3) is provided on any square face (8) of the unit main bodies (1), an insert groove (2), located on the same axis as the post (3), is provided on another square face (8), and a secondary post (7) can also be added to the unit main bodies (1).The building blocks can be assembled by single unit components into a model of various shapes and can also make the model simultaneously extend in two mutually perpendicular directions, thus making the whole model formed by building blocks more diverse. The building block also has the advantages of a simple structure, being compact, having low manufacturing costs, and being convenient to plug together. |
