Other details are summarized as follows for reference only.
The depth dimension stipulated the depth and the depth width in the Engineering Practice Law of Qing Dynasty.
(1) For a large building with stilts, the width-depth ratio of the open space is1:1.75 ~1:1.8.
(2) For buildings without beams and small buildings, the width-depth ratio of open space is1:1.62 ~1:1.2.
Therefore, the depth of a large building is generally 1.6-2 times of the width of the bay, and that of a small building is generally1.1-0/.2 times of the width of the bay.
1, width determination: determine the width of the room according to the door ruler; The size of the second room should be determined according to 8/ 10 of the width of the open room.
2. Determination of depth: small-sized buildings should not exceed five purlins and four steps, and seven purlins should be added with front and rear corridors; The depth of a large building is determined according to the number of bucket arches.
3. Determination of column height and diameter: the column height is 8/ 10 of the open space width, and the column diameter is11/column height.
4. Divided footing: the column height of small buildings is1100, and that of large buildings is 7/1000; The side foot of eaves column is1100 (or 7/ 1000) of column height, and there are no side feet for gold column and central column.
5. Ascending and descending (outflow and backwater): for large or small buildings without a bucket arch, it will rise to 310 of the height of the eaves column, 2/3 of the rafters, and13 of the rafters; The small size of the lower row is 4/5 of that of the upper row and the large size is 3/4 of that of the upper row.
