Lu Banchi, also known as "Lu Banchi" and "Lu Banchi", is a measuring tool used in building houses, similar to the ruler used by craftsmen. Usually used in woodworking, architecture, drawing and other fields. 1 m corresponds to the scale on Lubanchi 150.
The evolution of Lubanchi
The ancient book records that "Lu Banchi is one foot, four inches and four minutes, eight inches between feet, and one inch is accurate and one inch is eight minutes." The "bending ruler" is a carpenter's ruler used by ancient carpenters, and its length is the same as that of the building ruler promulgated by the Ministry of Industry of the imperial court in previous dynasties. Because the building in Ming and Qing Dynasties is 32 cm long, Lu Banchi is 46.08 cm long, and Lu Banchi is 5.76 cm per inch.
There are very few Lubanchi handed down from generation to generation. There is a Lu Banchi in the collection of Beijing Palace Museum, which is 46 cm long, which is very close to the length of Lu Banchi recorded in ancient books. There are two kinds of popular Lu Banchi in China, one is 42.9 cm and the other is 50.4 cm. At present, Lu Banchi with 42.9 cm constraint is the most widely used.
