Description

Dry-type connected node of assembled concrete beam column
Technical Field
The invention belongs to the technical field of buildings, and particularly relates to a dry type connection node of an assembled concrete beam column.
Background
The assembled concrete building is a concrete structure house building designed and built in a field assembly mode, wherein the prefabricated concrete building is mainly produced in a factory mode. The assembly method of the component generally comprises the steps of on-site post-pouring laminated layer concrete, steel bar anchoring post-pouring concrete connection 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 80 s of the 20 th century, the prefabricated large plate house popular in China has many hidden dangers and defects affecting the structural safety and normal use due to poor structural integrity, leakage, floor cracks and the like, and is gradually replaced by a cast-in-place concrete structure. 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.
With the acceleration of the process of building industrialization and residence industrialization in China and the continuous reduction of population bonus in China, the trend of the appearance of residence industrialization of the labor waste in the building industry is becoming obvious. The application of the fabricated concrete structure is newly changed into a new technology and a new form of the fabricated concrete structure of the residential building continuously and nationally in the current research hot spot. 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 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 RC 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, material 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 rest time for connecting the working procedures, realizing three-dimensional cross operation, reducing constructors, improving work efficiency, reducing material consumption and reducing environmental pollution, and providing guarantee for green construction. In addition, the assembled structure reduces construction waste (about 30% -40% of the total urban 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. The whole assembled building is generally limited to a multi-layer building with low requirements on low-layer or earthquake-proof fortification, and 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 an assembled integral structure.
The design construction technology of the fabricated concrete building is researched from the fifth sixty of the 20 th 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 time of the application of the fabricated concrete building in the 80 th century of the 20 th century, a fabricated concrete industrial building mode integrating design, manufacture, construction and installation is formed in many places of the whole country, the fabricated concrete building and a 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 changes 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 90 s of the 20 th century, and the fabricated single-layer industrial factory building system is widely applied at present. Other prefabricated building systems have few engineering applications. 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. Is the root cause of the long-term stagnation of the prefabricated structure.
