A Study on the Changes of Rafter Fixation Methods of the Jeonjagak(丁字閣) in the Later Joseon Period

Research reveals significant advancements in rafter fixation techniques during the later Joseon period, particularly at Jeongjagak. The study found that the use of rafter nails increased substantially and that the fixed parts were widened, enhancing the structural stability and bearing capabilities of these traditional Korean architectural elements. Analyzing 42 official reports from royal tombs, the researchers examined measurement methods for rafter amounts, changes in fixation techniques, installation methods for rafter nails, and connecting niddles. These findings highlight Jeongjagak's role as a government-constructed innovation that improved the durability and strength of wooden structures, offering valuable insights into the evolution of architectural engineering in Joseon-era Korea.
