Slab-type concrete building element - has notches formed parallel to side at join onto coupling eyes

摘要

The concrete constructional component is in slab form, with coupling members on two opposite sides to engage with those on adjacent components. These members comprise cylindrical eyes hinging on those of the adjacent components and of the same dia. as the slab thickness. Where the slab portion (1) joins onto the eyes, notches (6) are formed parallel to the slab side and the peripheral surfaces of the eyes (2) merge into the notches. The latter can be continued by chamfers (8) on the portions of the slab edge free from eyes.
