Split columns with locating features
A split column includes two half sections with locating features for aligning the half sections. A whole column is formed and then split into half sections. The locating features are formed on the inner surfaces of the half sections after the column is split into half sections.
1. A split column comprising:
a first half section;
a second half section; and
first and second locating features formed on respective inner surfaces of the first and second half sections to structurally facilitate alignment of the first and second half sections;
wherein the first locating feature comprises at least one groove defined between the inner surface of the first half section and a wall extending from that inner surface at a non-normal angle, and wherein said first and second locating features have complementary configurations.
2. The split column of claim 1 wherein the second locating feature comprises at least one complementary projection configured to fit in said groove when the first and second half section are aligned.
3. The split column of claim 1 wherein the first and second locating features are configured to vertically align the half sections.
4. The split column of claim 3 wherein the first locating feature comprises a plurality of longitudinally spaced grooves, and wherein the second locating feature comprises a plurality of longitudinally spaced projections that fit into the longitudinally spaced grooves.
5. The split column of claim 4 wherein the first and second locating features each further include at least one dowel hole for receiving a dowel pin.
6. The split column of claim 5 wherein at least one dowel hole is disposed between two of said plurality of longitudinally spaced grooves in the first locating feature and at least one dowel hole is disposed between two of said plurality of longitudinally spaced projections on the second locating feature.
7. The split column of claim 4 wherein said plurality of longitudinally spaced grooves and said plurality of longitudinally spaced projections are longitudinally extending and have defined longitudinal boundaries on the grooves' and projections' respective locating features, the longitudinal boundaries of the grooves and projections being spaced from an outer surface of the grooves' and projections' respective half section and being spaced from an inner surface of the grooves' and projections' respective locating feature.
8. The split column of claim 1 wherein said first and second locating features facilitate alignment of the first and second half sections to form a press fit connection.
9. The split column of claim 1 wherein said first and second locating features define a longitudinally extending chordal planar surface within the split column when said first and second half sections are aligned by said first and second locating features.
10. The split column of claim 1 , wherein edges of the first and second half sections are configured to abut in a non-interlocking manner when the first and second half sections are aligned.
11. The split column of claim 1 , wherein the first and second locating features structurally preclude edges of the first and second half sections from abutting unless the first and second half sections are aligned.
12. The split column of claim 1 , wherein the second locating feature comprises at least one complementary projection that extends past an edge of the second half section and that is configured to fit in said at least one groove when the half sections are aligned, and wherein the first locating feature also comprises at least one flat area that is vertically adjacent to the at least one groove, that is flush with an edge of the first half section, and that is configured to engage the at least one complementary projection, and thereby preclude the edges of the first and second half sections from abutting, when the at least one complementary projection is not vertically aligned with the at least one groove.
13. The split column of claim 1 , wherein the first and second locating features are formed proximal to ends of the first and second half sections.
14. The split column of claim 1 , wherein said wall extends from the inner surface of the first half section towards the second half section when the first and second half sections are aligned.
15. The split column of claim 1 , wherein the first locating feature is formed proximal to an edge of the first half section, and wherein said wall extends from the inner surface of the first half section towards that edge.
