Does anyone know anything about ancient Lubanchi?

The floor ruler, also known as "quasi-floor ruler", is a measuring tool used in building houses and houses, similar to the bending ruler used by craftsmen today. Lu Banchi, about 42.9 cm long, is said to have been written by a public school in Lu during the Spring and Autumn Period. Later, eight characters were added to the geomantic circle to measure the good and bad luck of houses and houses, which was called "door plan". Also known as "square", it is mainly used to check whether the planed plates, purlins and structures are vertical and whether the edges are at right angles to each other. 1 half a foot =0.8 foot. Soon after, Lubanchi appeared, Ding Lan ruler was integrated, and then inches and centimeters were integrated. It is an important tool for measurement and calibration.

Soon after, Lubanchi appeared, Ding Lan ruler was integrated, and then inches and centimeters were integrated. It is an important tool for measurement and calibration. Because of its special function, it is most widely displayed in geomantic culture and architectural culture. When building a house and making furniture, we should use this ruler to measure the height, width and length from the whole to each part, so as to get the scales related to Geely and avoid the scales related to disasters, so as to adapt to the psychology of praying for peace and auspiciousness. Judging from the marked text content, it is obviously related to the old astrology.

The floor ruler, also known as "quasi-floor ruler", is a measuring tool used in building houses and houses, similar to the bending ruler used by craftsmen today. It is divided into four rows from left to right, which are the traditional four scales: inch, Lu Banchi, Ding Lan ruler and centimeter. Lu Banchi, about 42.09 cm long, is said to have been written by the public transport class of Lu in the Spring and Autumn Period. Later, eight characters were added to the geomantic circle to measure the good or bad of the house, which was called "door plan".

Ancient Lu Banchi was 46.08 cm long.

The lengths of two modern Lu Banchi are 42.9 cm and 50.4 cm respectively.

The ancients attached great importance to size when building houses. Architects often use white rulers to determine the overall spatial dimensions of houses, such as height, depth and width. Carpenters use Lu Banchi to measure and determine the size of doorways. Relatively speaking, when modern people carry out architectural design and interior decoration, it is much more casual to determine the overall size of the house and the size of the door. Few people build houses and decorate rooms according to the white ruler and Lu Banchi's Geely size.

Lu Banchi is a popular building tool in ancient China. Generally used to measure and determine the size of residential doors and furniture. It is called "Luban Town Pool" and "Luban Zhou Chi" in Luban Jing and Luban Jian Zheng. In ancient times, people thought that the portal determined according to the auspicious size of Lu Banchi would shine brilliantly and bring good luck to the family, so Lu Banchi was also called "door light ruler". Because one foot in Lu Banchi is divided into eight inches, and each inch is written with expressions expressing various meanings, people also call Lu Banchi "eight-character foot", "door ruler" and "door meter".

Ancient Kanyu attached great importance to the application of Lu Banchi. "Ten Books of Yangzhai", a book of geomantic omen, said: "There are several kinds of door rulers in China, which have been tried and tested, but this ruler (Lu Banchi) is real. There is no difference between good luck and bad luck. Guy Xi lost his job in the class. His job was made of wood, so he was poor, so he created a ruler, and later he was named Lu Banchi. There are uninterrupted measuring doors, and all beds and room appliances should use this. "

How long is Lubanchi? What's the difference between ancient Lu Banchi and popular Lu Banchi now? 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." "Bending ruler" is a carpenter's ruler used by ancient carpenters, and its length is the same as 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. The Palace Museum in Beijing has a Lu Banchi, 46 cm long, which is very close to the length of Lu Banchi recorded in ancient books.

At present, there are two kinds of popular Lu Banchi in China, one is 42.9 cm and the other is 50.4 cm. The length of these two kinds of Lu half feet is different from that of ancient Lu half feet, so it can be said that these two kinds of Lu half feet are inaccurate.

Lu Banchi's eight characters are "wealth, illness, divorce, righteousness, official, robbery, harm and good luck", and some of them are written with the word "good luck". Generally speaking, the ancients thought that the size of the eight words "wealth, righteousness, official and auspicious" was auspicious, while the size of the other four words meant unlucky. But in practical application, Lu's eight characters are consistent. For example, the main entrance can be placed on the gate, but the ancients thought it was not suitable for the porch door; The official door is applicable to the yamen, not to the doors of ordinary people's homes; It is not appropriate to put the patient door on the gate, but it is "good luck" to put it on the toilet door. According to Lu Ban-ching, it is best for ordinary people to have "financial doors" and "auspicious doors" at home.

In ancient times, Lubanchi was not only the standard for installing doors in folk buildings, but also the standard for installing doors in royal buildings. The Practice of the Ministry of Industry and Social Security lists 24 kinds of door sizes of1ruled by Lu Banchi, including Jiafu 3 1 door, Yishun 3 1 door, Lu Guan 33 door and Fude 29 door.

In ancient books such as Lu Ban Jing and Shi Lin Guang Ji, some auspicious dimensions of portals are listed. "Lu Ban Jing" believes that a small single door should be opened two feet and one inch, that is, 67.2 cm is the main entrance; A single door should be 2 feet 8 inches, that is, 89.6 cm, which is an auspicious door; Small double doors should be four feet three inches, that is, 137.92 cm is the auspicious door; Double doors should be four feet, three inches and eight minutes, that is, 140.5438+06 cm, which is the financial door; The big double doors should be opened at five feet, six inches and six minutes, that is,181.12cm, which is an auspicious door.

Shilin Guangji believes that one inch (3.2 cm) is the "wealth" in Lubanchi; Six inches (19.2 cm) means "righteousness"; One foot and six inches (5 1.2 cm) is "wealth"; Two feet and one inch (67.2 cm) means "righteousness"; Two feet eight inches (89.6 cm) is "Ji"; Three feet and six inches (1 15.2 cm) means "righteousness"; Five feet six inches (179.2 cm) is "Ji"; Seven feet and one inch (227.2 cm) is "Ji"; Seven feet eight inches (249.6 cm) means "righteousness"; Eight feet and eight inches (28 1.6 cm) is "Ji"; One foot and one inch (323.2 cm) are "wealth", which are auspicious sizes and can be applied to all aspects of indoor layout.

It is also recorded in Huai Nan Zi Terrain Training: "Yu Nai made Tai Zhang walk from the East Pole to the West Pole, with a total of 233,575 steps, and made Shu Hai walk from the North Pole to the South Pole, with a total of 233,575 steps." To control floods on a large scale, preliminary investigations must be carried out from east to west and from south to north. Qiu and Shu Hai are both good people. Yu sent two people to the four directions to measure, and "Bu" became the most primitive unit for measuring the earth. "Flower King Gong Ji" said: "Wild degrees are step by step." This unit of measuring land step by step has even lasted for thousands of years. What are steps? Confucius Cong said, "Every move is enough, and it is a step." That is, the distance one leg walks is called "squat", and then the distance the other leg walks is called "step". All these show that Dayu finally achieved the purpose of water control by using various measuring methods.
