Description
Technical Field
The invention belongs to the technical field of buildings, and particularly relates to an assembled concrete column beam dry-type connecting structure.
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 component generally comprises a post-cast integral structure, a full-assembly structure connection and the like, and the steel bar connection can adopt methods of sleeve grouting connection, steel bar grout anchor lap joint connection 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.
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. By the 20 th century and the 80 th century, the application of the fabricated concrete building reaches the full prosperity, and a design, manufacture, construction and installation integrated fabricated concrete industrialized building mode 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 the social demand and the development of the construction technology, and the fabricated concrete building is gradually replaced by a full cast-in-place concrete building system by the middle of the 90 s of the 20 th century. At present, except that the application of an assembly type single-layer industrial factory building system is wider, the engineering application of other prefabricated assembly type building systems is very little. The seismic integrity of the prefabricated structure and the specialized research of design construction management are not enough, so that the poor technical integrity is the root cause of the long-term stagnation state of the prefabricated structure.
