3 FOUNDATIONS 4 of 6 12/10 Figure 4. Connection details for misaligned piles. Connections to misaligned piles (see drawings on figure 3 and details above) Note: Pileto-beam connections must be designed by an engineer. 1. The ability to construct the pile-to-beam connections designed by the engineer is directly dependent upon the accuracy of pile installation and alignment. 2. Misaligned piles will require the contractor to modify pile-to-beam connections in the field. 3. Badly misaligned piles will require removal and reinstallation, sister piles, or special connections, all to be determined by the engineer. 3.3: WOOD PILE-TO-BEAM CONNECTIONS HOME BUILDER’S GUIDE TO COASTAL CONSTRUCTION
Figure 5. Built-up beam connections, knee brace connections, and diagonal brace connections. D = Bolt diameter Note: Splicing the beam over a pile may increase the required pile diameter because of bolt/nail end distance requirements on the beam or bolt edge distance requirements on the pile. Pile Through-bolt(s) or lag screw(s) per design Diagonal brace Built-up beam Built-up beam 3.3: WOOD PILE-TO-BEAM CONNECTIONS Pile HOME BUILDER’S GUIDE TO COASTAL CONSTRUCTION Pile Approximately 12" (follow design) 7D typical (follow design) Note: This detail is not recommended. The connection shown has reduced capacity, may violate bolt edge-distance requirements, and can result in a weaker beam. Beam Bolted at Pile (Not Recommended) Nails or bolts Pile centerline Beam D = Bolt diameter Approximately 12" (follow design) Note: Glued laminated timber. Lapped Splice (Built-up Beam) Pile Countersunk through-bolts or lag screws per design 45º Knee Brace Approximately 4' (follow design) 7D Minimum D = Bolt diameter Knee Brace Connection on Square Pile* *Knee braces of this type can also be used on notched round piles. 7D for full bolt design value (follow design) Alternate faces to ensure adequate bolt end distances Note: Pile-to-beam connections must be designed by an engineer.
