| Summary: | 碩士 === 國立成功大學 === 建築學系碩博士班 === 96 === Taiwan traditional dei-do wooden frames have certain scope in the scale of the entry-direction of Central bay. However, there are no researches to explore that whether the frames of the scale have certain scope or follow certain rules to design the whole structural frames. The purpose of this study is to examine whether dei-do wooden frames have modular systems, and according to this to design the dimensions of frames.
The research target in this study focuses on lengthwise structure of two-point Hypostyle column in dei-do wooden frames. By reviewing literature we can find that the official wooden frames in the Sung Dynasty and the Manchu Dynasty are both in accordance with the basic modular to proceed the design of frames and architecture scale. Taiwan traditional great wooden frames originated from China, and as time goes by wooden frames evolved into unique methods of frames in Taiwan. This study believes that there should be basic modular in Taiwan traditional great wooden frames and then analyzes the basic modular.
“Ying Tsao Fa Shih” of the Sung Dynasty and “Gong Cheng Zuo Fa” of the Ching Dynasty used Tsai-Chih and Tou-Kou as their basic modular, which was a unit of Tou-Kung and Tou-Kou, respectively. This study compares the frame methods of Dei-Do form with the Sung Dynasty and the Ching Dynasty. The differences between dei-do form and the Sung and Ching Dynasty are the linking methods in tou-kung and frame components. In the official methods of “Ying Tsao Fa Shih” of the Sung Dynasty and “Gong Cheng Zuo Fa” of the Ching Dynasty, the parts of tou-kung used cross linkage between one Kung and another Kung, and then link crisscross Mortise of Tou. However,
the dei-do form of Taiwan Dei-Do wooden frames used Kung to link with Shu and Shuei to from a cross, and then link crisscross Mortise of Tou. Hence, this study takes Shu and Shuei into consideration as analyzing basic modular. The methods of analysis are based on the width of cross-section of frames, such as Kung, Shu and Shuei, then comparing these with the length, height and Tenon、Mortise of frames to understand if there exist a ratio relationship between modular of frames and the width of cross-section of frames. Next, this study compiles the width of Tou-Kou and the width of Shu, Shuei, main Kung, vice- Kung and Ji-She-Kung to proceed with the statistics analysis and diagnose the relationship between these statistics. Finally, after compiling the above-mentioned part, if it exists relationship or between these statistics or these statistics are equivalents, this study would compare other beam frames of the basic modular with entry-direction and side-direction to proceed with analysis.
The research results are included:
1. The cross-sections of Kung, Shu and Shuei are thin and long in Taiwan. Comparing to the height-to-width ratio of tsai-chih in the Sung Dynasty (1:1.5) and the Ching Dynasty (1:2), most height-to-width ratio of tsai-chih in Taiwan is greater than 1:2. The ratios between frames and width lie in certain multiples, but not fixed. As manufacturing notches, Kung, Shu and Shuei, they are one-forth to one to third of the width of cross-sections.
2. To compile the sizes of frames and the dimensions of this study’s setting modular.
3. To compile the distributive statistics of Dovetail Timber Connections and the dimensions of manufacturing notches.
