PROBLEM TO BE SOLVED: To provide a building block connecting structure in which a connecting pin can be easily inserted into a pin penetrating hole on a joint plate and a joint plate holding power of the connecting pin is strengthened.SOLUTION: In a building block connecting structure according to this invention, a joint plate 2 is placed between building blocks and pin engaging holes 15 are formed on opposed end faces of building blocks 11,12 at a position corresponding to pin penetrating holes 21 on the joint plate 2. A penetrating installation part 31 corresponding to the pin penetrating hole 21 is formed at an intermediate part. The penetrating installation part 31 on the connecting pin 3 with taper parts 35,36 on its both end parts is inserted in the pin penetrating hole 21 and the taper parts 35,36 are engaged in the pin engaging holes 15 of both building blocks 11,12. Concavities 4 are formed on an outer peripheral surface of the penetrating installation part 31 on the connecting pin 3 and a part 20 of a peripheral part of the pin penetrating hole on the joint plate 2 is stored in the concavity 4.SELECTED DRAWING: Figure 6B |
