Bracket structure and method for producing the same

Standardized modular bracket system for traditional architecture using interlocking tenon-and-groove bracket arms and plate-type blocks

This technology is a bracket structure for traditional buildings, assembled by fixing bracket units—formed by interlocking first and second bracket arms with central, extended, and end-coupling sections via fixing grooves—onto a block unit featuring assembly grooves on its top.

Brackets, composed of components like column capitals, blocks, and bracket arms, transfer roof loads to columns and serve decorative purposes. Because these components are joined through interlocking, their precise dimensions are critical, traditionally requiring skilled craftsmen to carve and assemble them. Furthermore, changing the bracket dimensions necessitated creating entirely new components, leading to a lack of compatibility between parts.

This technology features protrusions at one end of each bracket arm and corresponding coupling grooves at the other, allowing for longitudinal extension, or stepped sections on the top and bottom of the coupling parts for overlapping. The block unit is created by inserting first and second fastening members in a cross-direction into a plate-type fixing member with paired outer fastening grooves, with the number of groove pairs matching twice the number of bracket arms. Applicable to new hanok construction, cultural heritage restoration, and traditional-style public buildings, this system allows for factory-produced standardized parts, enabling unskilled labor to assemble brackets and accommodating dimension changes by simply extending the bracket arms.

Key Features:

• A first bracket arm comprising a central first fixing section, first extension sections at both ends, and first coupling sections at the tips, with a first fixing groove formed in the lower center of the fixing section
• A second bracket arm comprising a central second fixing section, second extension sections at both ends, and second coupling sections at the tips, with a second fixing groove formed in the upper center of the fixing section
• A protrusion formed at one end of the coupling sections and a corresponding coupling groove formed on the other
• A block unit consisting of a plate-type fixing member with multiple outer fastening grooves and first and second fastening members inserted in a cross-direction
