Description
Technical Field
The utility model belongs to the technical field of building structures, and relates to an energy-consumption damping beam column node for an assembled building.
Background
The assembled concrete building is a concrete structure house building which is designed and built in a field assembly mode by taking a concrete prefabricated part produced in a factory as a main part. The assembly method of the component generally comprises the steps of on-site post-pouring laminated layer concrete, post-pouring concrete connection of steel bar anchoring and the like, and the steel bar connection can be made by sleeve grouting connection, welding, mechanical connection, reserved hole lap joint connection and the like. In the eighties of the twentieth century, in the assembled prefabricated large-panel house popular in China, due to poor structural integrity, leakage, floor cracks and the like, many hidden dangers and defects affecting structural safety and normal use exist, and are gradually replaced by cast-in-place concrete structures. However, with the application of the currently emerging fabricated concrete structures, particularly, many advanced foreign technologies have been introduced in recent years, and new native fabricated concrete structure construction technologies are gradually developed.
Along with the acceleration of the progress of building industrialization and residence industrialization in China and the continuous reduction of population bonus in China, the appearance of labor waste in the building industry and the trend of residence industrialization are increasingly obvious. The application of the fabricated concrete structure is newly a current research hot spot, and new technologies and new forms of the fabricated concrete structure of the residential building are continuously emerging all over the country. The assembled reinforced concrete structure is one of important directions of building structure development in China, is beneficial to the development of building industrialization in China, improves the production efficiency, saves energy, develops green and environment-friendly buildings, and is beneficial to improving and guaranteeing the quality of building engineering. Compared with the cast-in-situ construction method, the fabricated reinforced concrete structure is beneficial to green construction, because the fabricated construction can better meet the requirements of land saving, energy saving, material saving, water saving, environmental protection and the like of the green construction, reduces the negative influence on the environment, including noise reduction, dust emission prevention, environmental pollution reduction, clean transportation, site interference reduction, water saving, electricity saving, material saving and other resources and energy sources, and follows the principle of sustainable development. In addition, the assembly structure can continuously finish a plurality of or all working procedures of the engineering in sequence, thereby reducing the types and the quantity of engineering machinery entering the engineering, eliminating the idle time for the connection of the working procedures, realizing the three-dimensional cross operation, reducing constructors, improving the work efficiency, reducing the material consumption and reducing the environmental pollution and providing a guarantee for the green construction. In addition, the assembled structure reduces construction waste (about 30-40% of the total amount of municipal waste) to a large extent, such as waste steel bars, waste iron wires, waste bamboo wood, waste concrete and the like.
The assembled concrete building can be divided into two main types of full assembly and partial assembly according to the degree of assembly. Fully assembled buildings are generally limited to multi-storey buildings with lower requirements for low-rise or earthquake fortification; the main components of the partially assembled concrete building are generally prefabricated components, and are connected on site through cast-in-place concrete to form the building with the assembled integral structure.
The design construction technology of the fabricated concrete building is researched from the fifth sixty of the twentieth century in China, a series of fabricated concrete building systems are formed, and typical building systems comprise fabricated single-layer industrial factory building systems, fabricated multi-layer frame building systems, fabricated large-plate building systems and the like. By the twentieth eighties, the application of the fabricated concrete building reaches the full period, and a fabricated concrete industrial building mode integrating design, manufacture, construction and installation is formed in many places of the whole country. The assembled concrete building and the masonry building adopting the prefabricated hollow floor slab become two main building systems, and the application popularization rate is more than 70%. Because of a plurality of limitations and defects of the functions and the physical properties of the fabricated building, the development level of the fabricated concrete building design and construction technology in China is not kept pace with the change of the social demands and the development of the building technology, the fabricated concrete building is gradually replaced by a full cast-in-place concrete building system in the middle ninety of the twentieth century, and other prefabricated building systems are seldom applied in engineering except that the fabricated single-layer industrial factory building system is widely applied at present. The integrity of the prefabricated structure earthquake resistance and the specialized research of design construction management are insufficient, so that the technical economy is poor, and the prefabricated structure is a root cause for causing the prefabricated structure to be in a stagnation state for a long time.
