  • Concrete slab sockets
    Patent number: 5941045
    Abstract: A dowel bar socket for concrete slab construction comprises a hollow elongate body (30, 31) having a mounting means (34) at a proximal end and a closed distal end (32). The socket is characterized in that the upper and lower portions of the body wall are parallel and provide a snug fit for a dowel bar to prevent movement in an upright direction. The hollow body tapers divergently from the distal end to the proximal end to permit limited lateral movement of a dowel bar as a curing concrete slab undergoes shrinking.
