What is the difference between five beams ancient buildings between five beams and seven beams

It is a beam with five purlins and a length of four steps.

The practice is the same as that of seven beams. Cut the material according to the pole, draw the flat water line, the head line, the wide and narrow line, and the bear back line; Nose, etc. If the small style does not make a purlin three pieces, the front and rear eaves can be made purlins.

Jinbu can be used as a substitute for the wooden mouth, the width and depth of the same as the pad plate mouth, the height of 4 cm. Round slow flute, chisel purlin and other operations.

The purlin is a horizontal member along the width of the building at the beam head. Its function is to fix the rafters directly and transfer the roof load down through the beams. The name of the purlin varies with the position of the column where the beam head is located, such as the eaves purlin above the eaves column, the gold purlin above the golden column, and the ridge purlin above the middle column.

Extended Materials. The five-frame beam-sitting frame is the main large wooden frame form of traditional folk buildings such as temples, ancestral halls, academies, and dwellings in southern Fujian. The study shows that the five-frame frame has the characteristics of lifting beams and wearing buckets.

Among them, three-way five-melon and two-way three-melon are its common forms. The practice of stacking buckets is mostly used on the beam and column joints.

It uses a curved fang and a kanban on the longitudinal connection frame, and its origin can be traced back to southern China during the Tang and Song dynasties. In the overhang structure of the cornice, it is overhanging with beam heads and ding heads and stably connected with components such as squatter bundles, hanging tubes, vertical firewood, and supporting wood, which is a typical overhang method of cornice in the popular area of the bucket frame in southern China.

The five-frame beam is the backbone member of the main body beam frame, which is four steps long, and supports five purlins on it. Seven beams, on which seven purlins are supported, and the length is the beam of the six-step frame.

Most of China's ancient buildings are based on wood structure as the main structural form, and the most common frame forms of beam frame structure are beam lifting type, bucket type, and beam lifting and bucket combination type. Among them, the beam frame is the main structural part in the ancient building. The bucket is located between the column and the beam, which has both a structural and decorative function.

In addition to this, there are two types of timber framing, namely dry bar type and well dry type.

In ancient timber frames, beams are an important horizontal stress member, and in larger buildings, beams are placed on top of bucket arches. In smaller buildings, the beams are placed directly on the column heads. Depending on their position, function, and shape, each has its own name and structure.

They mainly include: seven beams, five beams, three beams, six beams, four beams, double-step beams, moon beams, three-step beams, head beams, pick-tip beams and more than 30 kinds.

According to the number of purlins supported on the beam, it can be divided into: moon beam, three beams, four beams, five beams, six beams, and seven beams.

The practice is the same as that of seven beams. Press the pole to cut the material, draw the waterline

Head up line, wide and narrow line, bear back line; Do nose, etc. back operation. If the small style does not make a purlin three answers, the front and rear eaves can be made purlins. Jinbu can be used as a substitute for the wooden mouth, the width and depth of the same as the pad plate mouth, the height of 4 cm. Round slow flute, chisel purlin and other operations.

The frame beam is named after the number of purlin roots erected on it (also called the frame), such as three purlins above the beam is called three beams, and five purlins are called five beams.

Erection beam, a Chinese word, is a common saying in the Ming Dynasty army, calling the camp "erecting beam".

It seems that the one that supports three purlins on the beam is called "three beams", and the one with five purlins is called "five beams".

The five-frame beam is a beam with five purlins on the upper bearing and a length of a four-step frame. It is a very important beam in the building.

The name of the erection beam is the name of the Qing Dynasty, and for details, see the "Code of Engineering Practice" of the Ministry of Industry of the Qing Dynasty. Karpsen was right. According to the Song-style title, the three beams are divided into flat beams (above the four rafters directly below the ridge) and milk oaks according to their positions, and the five beams are called four rafters, and the head beam is called tie-in.
