Description

An assembled multi-story prestressed steel special-shaped column frame-diagonal support system

technical field

The invention relates to an assembled multi-story prestressed steel special-shaped column frame-diagonal support system, which belongs to the technical field of structural engineering.

Background technique

my country's annual urban and rural housing area is 2 billion square meters, of which more than 80% are high-energy buildings, and the energy consumption per unit building area in my country is more than twice that of developed countries. According to the statistics of the China Iron and Steel Association, in 2011, my country's steel output exceeded 700 million tons, ranking first in the world's steel output for 16 consecutive years. Our country is less than 4%. As the country with the largest construction scale and steel output in the world, China lags behind seriously in the development of steel structures for houses (including residences).

The implementation of my country's "Twelfth Five-Year Plan" has brought the construction industry into the era of energy conservation, emission reduction, and green environmental protection. The "Green Building Evaluation Standards" issued by the Ministry of Housing and Urban-Rural Development defines green buildings as: To save resources (land, energy, water, and materials), protect the environment, and reduce pollution to the greatest extent, provide people with healthy, applicable, and efficient use of space, and a building that coexists harmoniously with nature. This concept is an important strategic transformation for changing the mode of economic growth and promoting sustainable development, and it really provides a major opportunity for the innovation and industrialization of the corresponding system of steel structures for houses (residential buildings) in my country.

At present, the systematic research on high-rise steel structure residences at home and abroad is in its infancy, and the innovation of industrially assembled high-rise steel structure systems is imperative. A lot of welding is used in the construction of traditional steel structure residential buildings, the construction speed is slow, and the pollution to the environment is serious. The most important thing is that the quality of the welds is not suitable for control, which seriously affects the safety performance of the building.
