wall thickness of 0 14 u2033 this diameter and wall thickness is selected based on a rod spacing of approximately 2 u2032 0 u2033 assuming a 15 u2032 0 u2033 floor joist span and the associated structural demand to cantilever approximately 6 u2033 through a gap composed of brick veneer while having 14 u2033 stabilizer extension fig4 illustrates an expanded view of one end of the connector rod 9 a bolt 25 with external spiral threads 77 has its head 73 inserted into the end of the rod 9 preferably the bolt has a diameter of u00be u2033 making the inside face 71 of the pipe in close contact with a standard hexagonal head 12 of the u00be u2033 diameter bolt the bolt head 12 is welded at 72 and 73 to the inside face 71 of the rod the weld 73 may be a continuous butt weld made around the circumference of the rod 9 this single plane weld may not alone provide significant resistance to bolt rotation within the pipe 70 therefore six equally spaced holes are drilled around the circumference of the pipe 70 aligning with the external points of the hexagonal head 12 of the bolt 25 a plug weld 72 is made in each of these holes creating an additional plane of welds the connector rod 9 includes a cantilevered portion and a stabilizer extension portion 31 preferably the stabilizer extension portion is at least 12 inches long however the stabilizer extension may be shortened if desired thereby increasing rod shear forces increasing rod bearing forces and decreasing rod deflection or lengthened if desired thereby decreasing rod shear forces decreasing rod bearing forces and increasing rod deflection the stabilizer extension portion 31 of the connector rod extends through a supportive or u201c blocking u201d.
