After the Ming tower of Xiaoling is Baoding. At the foot of the mountain, there are seven regular script characters of "this tomb of Ming Taizu". Baoding, also known as Baocheng, is a large round mound of 325 to 400 meters. It is surrounded by brick walls, and the walls are based on stones. The height of the mound is about 7 meters up and down, and the thickness of the wall top is 2.1 meters. On the top of the pagoda, there are towering trees, under which Zhu Yuanzhang and empress Ma are buried.

Building components

The components of ancient Chinese architecture were originally used to protect the roof ridge from rain erosion, but later became more and more decorative. Most of the materials used were metal or glass. They were located in the center of the central axis of the building, and their shapes were round, girdle round, pavilion shaped, or pagoda shaped. It is rich in decoration.

building

There are four cities, Shinto, Beidian, Wenwu square gate, minglou and Baocheng. Nearby, there are plum blossom mountain, Bo'ai Pavilion, secret fragrance Pavilion, cherry blossom garden, newly built Red Chamber art and culture garden, underwater world, and celebrity tombs: Sun Quan tomb site, Liao Zhongkai and He Xiangning

Mound

The tomb of the owner of the royal mausoleum is a high mound called Baoding, and the underground palace is under it. Baoding is made of lime, sand and loess. It is compacted layer by layer, poured with glutinous rice soup and iron nails, so it is very solid.

Baoding grid

development

Architects for any building modeling, are repeatedly considered, strive to break through the traditional, especially for high-rise buildings. For the whole building, the top selection of high-rise building is the finishing touch, especially important. Many architects call the top of a high-rise building a crown, just like the crown of a building. The traditional shapes of Baoding are strip and matchbox, and various shapes emerge one after another, such as spherical, hemispherical, pyramid and so on. In these forms, the most direct and feasible way is to use the grid structure to realize the architect's intention.

The shape of high-rise roof made of grid structure can be changed at will to meet the requirements of designers. In addition, it has the following characteristics:

1) The self weight of the structure is light, which is about the destructive effect of the reinforced house. However, it should be noted that the ring beam has little resistance to shear failure of multi-storey brick building walls. Therefore, if the number of building anti-seismic brick walls is insufficient, or the anti-seismic strength of the wall itself is too poor, and only by adding ring beams to improve is not effective.

2) To ensure the integrity of multi-storey brick house is the key to the seismic structural design: to ensure the vertical and horizontal wall biting masonry, so as to improve the integrity of the brick wall; to ensure the quality of precast slab pouring joint, to strengthen the connection of slab, beam and ring beam, so as to ensure the connection of the floor (roof), so as to ensure the integrity of the brick wall and the floor (roof).

characteristic

The design of high-rise Baoding grid structure has both similarities and characteristics compared with the general grid structure. It needs to combine the high-rise building structure, fully consider its mechanical characteristics, in which the structure selection is particularly important, that is, according to the characteristics of each building shape, choose an economic and reliable grid form. When the span is small and the supporting conditions are good, the single-layer reticulated shell structure is the most economical; when the span is large and the supporting points are few, the deformation and node displacement of the single-layer reticulated shell are large, which can not meet the requirements of stress and use, so it should be located on the supporting surface In this way, the stress and deformation requirements can be satisfied.

matters needing attention

The roof material should be carefully selected in the design of high-rise roof, which is consistent with the function required by the building. Some space trusses require lighting and ventilation, while others require heat insulation. Improper selection will cause great waste. Starting from the design of space trusses, the roof scheme and project cost should be comprehensively considered. At the same time, as the Baoding is generally located in the highest part of high-rise buildings, the lightning protection, lightning suppression system and navigation equipment of buildings should be fully considered.
