Dowel bar assembly and mechanical connector
A mechanical connector for securing a dowel rod to a frame of a dowel bar assembly as well as a dowel bar assembly are detailed. Each embodiment of the mechanical connector includes a portion to receive the dowel bar. A second portion of the mechanical connector engages the frame of the dowel bar assembly. A third portion of the mechanical connector engages a separate part of the frame further stabilizing the mechanical connector and frame.
1. A connecting device for a dowel bar and frame wherein the frame includes a U-shaped portion over the dowel bar and the frame also includes a horizontal cross-member, the connecting device comprising:
a spring coil wire;
the spring coil wire comprising at least one circular member;
the at least one circular member forming a cavity;
wherein the cavity is capable of receiving the dowel bar;
wherein the at least one circular member secures the dowel bar;
the spring coil wire having a first end and a second end;
wherein the second end has a hook for engaging the horizontal cross-member of the frame;
the spring coil wire comprising an arm longitudinally extending from the at least one circular member;
wherein a longitudinal axis of the arm is parallel to a longitudinal axis of the dowel bar;
wherein the arm prevents movement of the U-shaped portion of the frame toward the at least one circular member;
wherein the connecting device secures the dowel bar and the frame without utilizing welds;
the spring coil wire bendable wherein the second end can be selectively moved to disengage the spring coil wire from the frame.
2. The connecting device of claim 1 , wherein:
the second end substantially curved around the horizontal cross-member of the frame.
3. The connecting device of claim 1 , wherein:
there is a plurality of circular members.
4. The connecting device of claim 3 , wherein:
the first end can be selectively moved to disengage at least one circular member from the dowel bar.
5. A connecting device for a dowel bar and frame wherein the frame includes a U-shaped portion over the dowel bar and the frame also includes a horizontal cross-member, comprising:
a spring coil wire;
the spring coil wire comprising at least one circular member;
the at least one circular member forming a cavity wherein the cavity is capable of receiving a dowel bar;
the spring coil wire has a first end and a second end wherein the second end is curved to secure the horizontal cross-member of the frame;
the second end is a first longitudinal distance from the at least one circular member; the spring coil wire has an arm extending to a point a second longitudinal distance from the at least one circular member;
the second distance greater than the first distance;
wherein the spring coil wire maintains the U-shaped portion of the frame at least the second distance from the at least one circular member.
6. The connecting device of claim 5 , wherein:
the spring coil wire is bendable wherein the first end and the second end can be selectively moved to disengage the wire from the frame.
7. The connecting device of claim 6 , further comprising:
a plurality of circular members.
8. A connecting device for a dowel bar and frame wherein the frame includes a U-shaped portion over the dowel bar and the frame also includes a horizontal cross-member, the connecting device comprising:
at least one circular member;
the at least one circular member forming a cavity wherein the cavity is capable of receiving a dowel bar;
a spring coil wire having a first end and a second end wherein the second end has an arm with a longitudinal axis parallel to a longitudinal axis of the dowel bar and a hook to secure the horizontal cross-member of the frame;
the hook and the at least one circular member allow a mechanical connection
wherein the connecting device, secures the dowel bar and the frame without utilizing welds.
9. The connecting device of claim 8 , wherein:
there is a plurality of circular members.
