MAGNUM® MHLS1005 Boardwalk H-Bracing System

Description

The Magnum MHLS1005 Boardwalk H-Bracing System consists of a 3.0? O.D. cross tube with 3.5? I.D. collar tubes for connection to Magnum
MH3521 helical pile shafts and steel angle brackets got connection to a dimension lumber, engineered wood, or rough timber cross beam. The H brace system can accommodate 6 ft and 8 ft wide boardwalks with clear heights above ground from 24″ to 48″. H-Braces can be used for boardwalks above this height, but Magnum generally recommends adding Magnum helical anchors as tie-backs at a 45 deg angle at 16 to 24 ft on center along the length of the boardwalk for improved lateral performance. Custom H-brace sizes are available for narrower or wider boardwalks. H-braces provide lateral resistance and sideway stabilization. Each plate steel bracket is fastened to wooden cross beam with (4) ?” lag bolts. Collar tubes are fastened to helical pile shaft using (1) 1″ diameter through bolt on each side. The entire assembly can be hot-dip galvanized for increased corrosion resistance.

Installation Note:
Layout and install MH3521 helical pile foundations for boardwalk bents. Cut-off helical pile shafts at required elevation. Drill holes in pile shaft to facilitate attachment to H-brace. Mount H-brace to tops of piles and secure with through bolts. Place wood cross beam and attach with lag bolts.

*Lateral capacity is based on maximum structural resistance. Lateral capacity of brace/pile system depends on ground conditions and should be determined by a design professional for the specific job site and subsurface conditions. Contact Magnum technical support for design assistance.

Allowable Lateral Capacity 2 Tons*
