Description
Technical Field
The invention belongs to the technical field of buildings, and particularly relates to a dry type connecting node of an assembled concrete beam column.
Background
The prefabricated concrete building is a building with a concrete structure designed and built in a field assembly mode, wherein the prefabricated concrete components are mainly produced in a factory. The assembly method of the member generally comprises the steps of on-site post-pouring laminated concrete, steel bar anchoring post-pouring concrete connection and the like, and the steel bar connection can adopt the methods of sleeve grouting connection, welding, mechanical connection, reserved hole lap joint and the like. In the 80 s of the 20 th century, the prefabricated large-plate house popular in China has many hidden dangers and defects influencing the safety and normal use of the structure due to poor structural integrity, leakage, floor slab cracks and the like, and is gradually replaced by a cast-in-place concrete structure. However, with the application of the currently emerging prefabricated concrete structure, especially with the introduction of a plurality of foreign advanced technologies in recent years, a new technology for constructing a native prefabricated concrete structure is gradually formed.
With the acceleration of the 'building industrialization and housing industrialization' process in China and the continuous reduction of 'population dividends' in China, the trend of housing industrialization for the shortage of labor in the building industry is increasingly obvious. The application of the prefabricated concrete structure becomes a new technology and a new form of the prefabricated concrete structure of the residential buildings continuously emerged all over the country of the current research hotspot. The assembled reinforced concrete structure is one of the important directions for the development of building structures in China, is beneficial to the development of industrialization of buildings in China, improves the production efficiency, saves energy, develops green and environment-friendly buildings, and is beneficial to improving and ensuring the quality of building engineering. Compared with a cast-in-place construction method, the assembly type RC structure is beneficial to green construction, because the assembly type construction can better meet the requirements of land saving, energy saving, material saving, water saving, environmental protection and the like of the green construction, the negative effects on the environment are reduced, including noise reduction, dust prevention, environmental pollution reduction, clean transportation, field interference reduction, water, electricity, material and other resources and energy sources, and the principle of sustainable development is followed. Moreover, the assembly type structure can continuously finish a plurality of or all working procedures of the engineering in sequence, thereby reducing the types and the quantity of the engineering machinery entering the field, eliminating idle time of procedure connection, realizing the three-dimensional crossing operation, reducing constructors, improving the working efficiency, reducing the material consumption, reducing the environmental pollution and providing the guarantee for green construction. In addition, the fabricated structure reduces construction waste (about 30% -40% of the total amount of urban waste) to a great extent, such as waste steel bars, waste iron wires, waste bamboo and wood, waste concrete and the like.
The fabricated concrete building can be divided into a full assembly type and a partial assembly type according to the degree of assembly. The fully assembled building is generally limited to a multi-storey building with low requirements for seismic fortification or a low-rise building; the main components of the partially assembled concrete building are generally prefabricated components and are connected through cast-in-place concrete on site to form the building with an assembled integral structure.
The design and construction technology of the fabricated concrete building is researched from the fifties and sixties of the 20 th century in China, a series of fabricated concrete building systems are formed, and typical building systems comprise a fabricated single-layer industrial factory building system, a fabricated multi-layer frame building system, a fabricated large-plate building system and the like. The application of the fabricated concrete building reaches the full prosperous period in the 80 th of the 20 th century, and a fabricated concrete industrialized building mode integrating design, manufacture, construction and installation is formed in many places in the country, the fabricated concrete building and the masonry building adopting the prefabricated hollow floor slab become two main building systems, and the application popularization rate reaches more than 70%. Because the function and physical performance of the fabricated building have many limitations and defects, the level of the design and the development of the construction technology of the fabricated concrete building in China cannot keep up with the change of social requirements and the development of the construction technology, and the fabricated concrete building is gradually replaced by a full cast-in-place concrete building system in the middle of the 90 s of the 20 th century, so that the fabricated concrete building is widely applied to the fabricated single-layer industrial factory building system at present. Other prefabricated building systems have very few engineering applications. The seismic integrity of the prefabricated structure and the specialized research of design, construction and management are not enough, so that the technical economy is poor. Is the root cause of the long-term stagnation of the prefabricated structure.
