Abstract
A precast plinth for supporting an associated object, such as a rail of a railway track, includes an elongated body made of a material including concrete. The plinth includes an upper face, a lower face, a first side face, a second side face and first and second end faces. The first and second side faces taper away from each other from the upper face to the lower face. A leveling hole can extend from the upper face to the lower face with a threaded leveling insert located in the leveling hole. A grout hole can extend from the upper face to a lower face in a spaced manner from the leveling hole.
Claims14
A precast plinth for supporting an associated object, comprising:
- an elongated body comprising a concrete material and including an upper face, a lower face, a first side face and a second side face and first and second end faces, wherein said first and second side faces taper away from each other from said upper face to said lower face;
- a grout hole extending from said upper face to said lower face;
- a fastener hole extending from said upper face to said lower face, said fastener hole being spaced from said grout hole;
- a leveling hole extending in said elongated body from said upper face to said lower face, said leveling hole being spaced from said grout hole and said fastener hole;
- and
- a leveling insert located in said leveling hole, said insert cooperating with an associated leveling fastener that selectively extends in said leveling hole.
A plinth assembly including a series of spaced precast plinths generally aligned along a longitudinal axis for supporting an associated railway track, each plinth comprising:
- a generally rectangular body including an upper face and a lower face;
- a leveling hole extending from said upper face to said lower face;
- a threaded leveling insert located in said leveling hole, said insert cooperating with an associated leveling screw that selectively extends in said leveling hole;
- and,
- a grout hole extending from said upper face to said lower face, said grout hole being spaced from said leveling hole.
A plinth assembly for supporting an associated rail, comprising:
- an elongated body including an upper face, a lower face, and first and second end faces;
- at least one leveling hole extending in said elongated body from said upper face to said lower face;
- and
- a leveling insert located in said at least one leveling hole, said leveling insert cooperating with an associated leveling fastener which selectively extends in said leveling hole to allow the plinth assembly to be leveled in relation to a subjacent support surface.
