Spacer end cap for reinforcing rods in steel reinforced concrete

摘要

The end cap fits on the end (1) of a concrete reinforcing rod, and comprises a sleeve (3) bearing at its closed end (4) against the shuttering, while the rod fits in an axial opening (5) at the other end. Clamping protrusions (6) inside the opening secure the rod.The protrusions consist of annular or spiral hard elastic lips one behind the other in the axial direction. The bottom (7) of the opening is at a predetermined minimum distance from the closed end of the sleeve, which can be of hard plastic. The clear internal diameter of the opening can be less than the external diameter of the rod, and it can have a tapering face (8) at the insertion end.
