Concealed Connections for Mass Timber Glulam Columns
Concealed column connections are crucial for mass timber construction, offering seamless integration, structural integrity, and enhanced aesthetics. Designed for post-and-beam construction, these connectors maintain the visual appeal of timber while ensuring high load capacities and ease of installation.
Strength, simplicity, and versatility: Introducing MCT™, MCB™, MCBS™
The MCT mass timber column tie connects two columns together while allowing the vertical download to be transferred by column-to-column bearing. The MCT can be used on a wide variety of column sizes and is compatible with the Simpson Strong-Tie® line of concealed beam hangers (CBH™, ACBH™, SCBH™, HSKP™), making it ideal for use in post-and-beam style construction.
The MCB and MCBS mass timber column bases provide standardized connections between glulam columns and concrete foundations or supports. Of the two connection types, the MCB is the most economical option for use in conditions where a standoff between the column and concrete is not required. The MCBS provides the highest download capacity option for a given column size and can be used where a standoff is required. Examples include when the top of the column's foundation is located below the slab on grade, or when additional separation between the wood and concrete is desired architecturally or for moisture protection.
