<p>Construction blocks which can be assembled into various three-dimensional objects by changing the angle of connection between block plates by a joint. The construction blocks comprise a combination of block plates (1) and a joint (2). The block plates (1) have, in a plan view, a regular triangle shape and a square shape, and the joint (2) has plugs (10) projecting in at least two directions. The plugs (10) of the joint (2) are engaged with the block plates (1) to connect the block plates (1) to each other. The block plates (1) each have bar-like sections (4) extending along sides of the outer periphery of the block plate and connected between corner sections (3), and also each have a space section (5) facing the inner side of the bar-like sections (4). When the plugs (10) of the joint (2) are fitted to bar-like sections (4) of the block plates (1), the space sections (5) prevent interference between the plugs (10) and the block plates (1). A joint section (11) for interconnecting base ends of the plugs (10) also does not interfere with the outer periphery of the block plates (1), and as a result, the block plates (1) and the joint (2) can rotate about the bar-like sections (4) relative to each other.</p> |
