Moment resistant building column insert system and method

A moment resistant building column insert system, comprising:

• a. a first column of generally tubular shape having a first column top end and a first column bottom end;
• b. a second column of generally tubular shape having a second column top end and a second column bottom end, wherein said second column bottom end has through-holes arranged in a pattern that are transverse to a length of said tube;
• c. a column insert, wherein said insert is sized to fit within said building columns, whereby said insert has a top half having through-holes arranged in said pattern and a bottom half inserted to said first column top end and welded thereto;
• and
• d. insert connectors, wherein said insert connector comprises;
• i. a threaded element incorporated to an inside wall of said insert and concentric to said column insert through-hole;
• and
• ii. a connection bolt;
• wherein said insert top end is inserted to said second column bottom end and said second column hole pattern is aligned with said insert hole pattern, wherein said connection bolts are inserted through said building column through-holes, through said column insert though holes and into said threaded elements and pre-tensioned thereto, wherein deforming or crushing of said first column and said second column is prevented by said pre-hardened structural filler during said pre-tensioning.

A moment resistant building column insert, comprising:

• a. an insert column of generally tubular shape;
• b. a pre-hardened structural filler disposed within said insert column;
• c. a pattern of through-holes transverse to a length of said insert column and through said pre-hardened structural filler;
• d. at least a pair of erection through holes disposed through a wall of said insert column;
• e. at least a pair of threaded elements incorporated to an inner wall of said insert column and disposed concentric to said pair of erection holes;
• f. a threaded element cover disposed over each said threaded element, wherein said threaded element cover is surrounded by said pre-hardened structural filler, wherein said threaded element cover forms a cavity around said threaded element within said pre-hardened structural filler, wherein said threaded element cover is disposed to protect said threaded elements from contamination by said structural filler;
• and
• g. an insert positioning element disposed axially along said column, wherein said insert positioning element comprises a positioning through-hole disposed for receiving a hoist end there though.
