Abstract

A dowel supporting device that includes a substantially hollow tube having a top end and a bottom end. An opening may be formed at the top end and a base may be formed at the bottom end. The base of the dowel supporting device may be fastened to a concrete deck. Concrete may be poured into the concrete deck. When dowels are ready to be used, the dowels may be inserted and secured to the dowel supporting device.

Claims

1. A dowel supporting device comprising:

a substantially hollow tube having a top end and a bottom end distal from the top end, wherein the substantially hollow tube forms an opening at the top end leading into the substantially hollow tube, wherein the tube is sized to receive and secure a dowel by insertion of a dowel through the opening at the top end; and

a base at the bottom end of the hollow tube distal from the top end, wherein the base is supported by a concrete deck such that the hollow tube is in an upright vertical position relative to the concrete deck, wherein the concrete deck is a substantially horizontal surface configured to receive a concrete pour to produce a substantially horizontal concrete slab, wherein the dowel is inserted into the opening at the top end of the hollow tube after the concrete around the hollow tube has solidified and wherein the dowel is supported by the hollow tube in an upright vertical position.

2. The dowel supporting device of claim 1, wherein the tube further comprises at least a leg section near the bottom end and a middle section above the leg section, wherein the leg section has a larger diameter than the middle section, thereby forming a lip.

3. The dowel supporting device of claim 2, wherein the tube further comprises an upper tube section at the top end, wherein the upper tube section has a smaller diameter than the middle section.

4. The dowel supporting device of claim 2, further comprising a plurality of straight ties each having a substantially flat surface and a plurality of openings formed to fit around the middle section and rest against the lip of the leg section, wherein the ties are placed over the plurality of substantially hollow tubes to vertically align said tubes and wherein the plurality of straight ties are pivotally disposed relative to one another.

5. The dowel supporting device of claim 1, further comprising a fastening component which secures the base to the concrete deck.

6. The dowel supporting device of claim 1, further comprising a thin sealed covering at the top end of the hollow tube to cover the opening at the top end during a concrete pour, and wherein the covering is punctured by the dowel during dowel insertion after the concrete solidifies around the tube.

7. The dowel supporting device of claim 1, wherein the dowel is secured within the hollow tube after insertion of the dowel into the tube.

8. The dowel supporting device of claim 7, further comprising a glue within the hollow tube which secures the dowel within the hollow tube after insertion of the dowel.

9. A dowel supporting device comprising:

a plurality of substantially hollow tubes each having a top end and a bottom end distal from the top end, wherein each substantially hollow tube forms an opening at the top end leading into the substantially hollow tube, wherein the tube is sized to receive and secure a dowel by insertion of a dowel through the opening at the top end;

a base at the bottom end of each hollow tube distal from the top end, wherein the base is supported by a concrete deck such that each hollow tube is in an upright vertical position relative to the concrete deck, wherein the concrete deck is a substantially horizontal surface configured to receive a concrete pour to produce a substantially horizontal concrete slab, wherein the dowels are inserted into the openings at the top ends of the hollow tubes after the concrete around the hollow tubes has solidified and wherein the dowels are supported by the hollow tubes in an upright vertical position; and

a plurality of straight ties comprising a plurality of openings formed to fit around a plurality of hollow tubes, wherein the ties are placed over the plurality of substantially hollow tubes to vertically align said tubes and wherein the plurality of straight ties are pivotally connected to one another.

10. The dowel supporting device of claim 9, wherein the tube further comprises at least a leg section near the bottom end and a middle section above the leg section, wherein the leg section has a larger diameter than the middle section, thereby forming a lip.

11. The dowel supporting device of claim 9, wherein the tube further comprises an upper tube section at the top end, wherein the upper tube section has a smaller diameter than the middle section.

12. The dowel supporting device of claim 9, further comprising a thin sealed covering at the top end of the hollow tube to cover the opening at the top end during a concrete pour, and wherein the covering is punctured by the dowel during dowel insertion after the concrete solidifies around the tube.

13. The dowel supporting device of claim 9, wherein the dowel is secured within the hollow tube after insertion of the dowel into the tube.

14. The dowel supporting device of claim 13, further comprising a glue within the hollow tube which secures the dowel within the hollow tube after insertion of the dowel.

15. A dowel supporting device comprising:

a substantially hollow tube having a top end and a bottom end distal from the top end, wherein the substantially hollow tube forms an opening at the top end leading into the substantially hollow tube, wherein the tube is sized to receive and secure a dowel by insertion of a dowel through the opening at the top end; and

a base at the bottom end of the hollow tube distal from the top end, wherein the base is supported by a concrete deck such that the hollow tube is in an upright vertical position relative to the concrete deck, wherein the concrete deck is a substantially horizontal surface configured to receive a concrete pour to produce a substantially horizontal concrete slab, wherein the dowel is inserted into the opening at the top end of the hollow tube after solidifying of the concrete around the hollow tube, wherein the dowel is supported by the hollow tube in an upright vertical position and wherein a thin sealed covering at the top end of the hollow tube covers the opening at the top end during a concrete pour, and wherein the covering is punctured by the dowel during dowel insertion after the concrete solidifies around the tube.

16. The dowel supporting device of claim 15, wherein the tube further comprises at least a leg section near the bottom end and a middle section above the leg section, wherein the leg section has a larger diameter than the middle section, thereby forming a lip.

17. The dowel supporting device of claim 15, wherein the tube further comprises an upper tube section at the top end, wherein the upper tube section has a smaller diameter than the middle section.

18. The dowel supporting device of claim 15, further comprising a plurality of straight ties having a substantially flat surface and a plurality of openings formed to fit around the middle section and rest against the lip of the leg section, wherein the ties are placed over the plurality of substantially hollow tubes to vertically align said tubes and wherein the plurality of straight ties are pivotally disposed relative to one another.

19. The dowel supporting device of claim 15, wherein the dowel is secured within the hollow tube after insertion of the dowel into the tube.

20. The dowel supporting device of claim 19, further comprising a glue within the hollow tube which secures the dowel within the hollow tube after insertion of the dowel.
