摘 要 万佛殿营造尺307.476毫米，每尺10大寸，12小寸，符合唐宋时期大小寸制度。材宽5大寸，合6小寸。单材8.4小寸，栔4小寸，足材12.4小寸。通面阔450小寸合375大寸。通进深420小寸合350大寸。明间面阔174小寸合145大寸。心间进深144小寸合120大寸。梢间138小寸合115大寸。铺作高72小寸，铺作外跳57小寸，柱头铺作最宽处为69小寸。屋举138小寸，折屋以是衰分计算而来。建筑外形是整数尺寸约束下的比例关系。Abstract :The construction ruler (Yingzao chi) of Wanfo Hall measures 307.476mm. Each chi is divided into 10 large cun as well as 12 small cun, conforming to the long - short ruler system of the Tang and Song dynasties.The width of the cai is 5 large cun, equivalent to 6 small cun. The Dang cai(single-sized timbers) is 8.4 small cun, the qi (another related unit) is 4 small cun, and the Zucai(the full-sized timbers) is 12.4 small cun.TheTong Mian Kuo of the building is 450 small cun, equivalent to 375 large cun. The Tong Jin Shen is 420 small cun, equivalent to 350 large cun. The width of the central bay is 174 small cun, equal to 145 large cun. the width of the central bay in the depth direction is144 small cun.The width of the side bay is 138 small cun, equivalent to 115 large cun.The Puzuo (bracket set) is 72 small cun in height, the outer projection of the Puzuo is 57 small cun, and the widest part of the Puzuo measures 69 small cun.The height of the ridged purlin (Wu Ju) is 138 small cun. The calculation of the roof slope (Ju Zhe) is derived through cuifen (Calculate according to the proportion). The architectural appearance exhibits proportional relationships within the constraints of integer dimensions.
