Abstract:
A building block (100) comprises a first mating portion and a second mating portion which are complementary. The first mating portion comprises a mating protrusion (140) which defines an axially extending through bore (144) and the second mating portion comprises an axially extending mating receptacle (180) which is complementary to the mating protrusion (140). The mating protrusion (140) and the mating receptacle (180) are in communication via the through bore (144), and a fastener anchoring device (146) adapted for engaging with an engagement means (920) of a fastener (900) is formed inside the through bore (144). The through bore (144) is adapted to permit axial insertion of the engagement means (920) of the fastener (900) into the mating protrusion (140). The fastener anchoring device (146) is adapted to obstruct axial passage of the engagement means (920) until the engagement means (920) overcomes the obstruction by negotiating rotationally with the fastener anchoring device (146) to thereby gain axial advancement and enter into engagement with the fastener anchoring device (146).
