Description

Prefabricated concrete wall panel with reinforcement avoidance and reinforcement connection

technical field

The invention relates to a prefabricated concrete structure used in energy-saving buildings, in particular to an assembled concrete wall panel for avoiding and strengthening connection of steel bars.

Background technique

Prefabricated concrete buildings refer to prefabricated concrete components produced in factories. Concrete structures are designed and constructed by on-site assembly. The assembly methods of components generally include on-site post-pouring of superimposed layer concrete, steel anchoring and post-casting concrete connection, etc. The steel bar connection can be done by sleeve grouting connection, welding, mechanical connection and reserved hole lap connection. In the 1980s, the prefabricated prefabricated large slab houses that were popular in my country, due to poor structural integrity, leakage, floor cracks and other reasons, had many hidden dangers and defects that affected the safety and normal use of the structure, and were gradually replaced by cast-in-place concrete structures. . However, with the application of the current emerging prefabricated concrete structures, especially the introduction of many foreign advanced technologies in recent years, localized new technologies for the construction of prefabricated concrete structures are gradually being formed.

With the acceleration of the process of "construction industrialization and housing industrialization" in China, as well as the continuous reduction of China's "demographic dividend", the labor shortage in the construction industry has appeared, and the trend of residential industrialization has become increasingly obvious. The application of prefabricated concrete structures has become a current research hotspot again. New technologies and new forms of prefabricated concrete structures for residential buildings are emerging all over the country. Prefabricated reinforced concrete structure is one of the important directions for the development of building structures in my country. It is conducive to the development of building industrialization in China, improving production efficiency, saving energy, developing green and environmentally friendly buildings, and helping to improve and ensure the quality of construction projects. Compared with the cast-in-place construction method, the prefabricated RC structure is conducive to green construction, because the prefabricated construction can better meet the requirements of green construction, such as land saving, energy saving, material saving, water saving and environmental protection, and reduce the negative impact on the environment. Including reducing noise, preventing dust, reducing environmental pollution, clean transportation, reducing site disturbance, saving water, electricity, materials and other resources and energy, following the principle of sustainable development. Moreover, the prefabricated structure can continuously complete multiple or all processes of the project in sequence, thereby reducing the type and quantity of construction machinery entering the site, eliminating the idle time of process connection, realizing three-dimensional cross operation, reducing construction personnel, and improving work efficiency. , Reduce material consumption, reduce environmental pollution, and provide guarantee for green construction. In addition, the prefabricated structure reduces construction waste to a large extent (accounting for 30%-40% of the total urban waste), such as waste steel bars, waste iron wires, waste bamboo wood, waste concrete, etc.

North America is mainly dominated by the United States and Canada. Due to the long-term research and promotion of prefabricated buildings by the Precast/Prestressed Concrete Association (PCI), the relevant standards and specifications for precast concrete are also perfect. Therefore, its prefabricated concrete building applications are very common. Prefabricated buildings in North America mainly include two series of building prefabricated exterior walls and structural prefabricated components. The common feature of prefabricated components is the combination of large-scale and prestressed. Structural reinforcement and connection configurations can be optimized. Reduce the workload of production and installation, shorten the construction period, and fully reflect the characteristics of industrialization, standardization and technical economy. In the 20th century, prefabricated buildings in North America were mainly used in low-rise, non-seismically fortified areas. Due to the impact of earthquakes in the California area, in recent years, great attention has been paid to the engineering application technology research of earthquake-resistant and mid-to-high-rise prefabricated structures. PCI recently published the book "Seismic Design of Precast Concrete Structures", which systematically analyzes the seismic design of prefabricated buildings from a theoretical and practical perspective, summarizes the latest scientific research results of seismic design of many precast structures, and provides guidance for the design and engineering applications of precast structures. Promotion has a strong guiding significance.

Europe is the birthplace of prefabricated buildings, and the road to building industrialization began as early as the 17th century. After the Second World War, due to the shortage of labor resources, Europe further researched and explored the mode of construction industrialization. Whether it is economically developed Northern Europe, Western Europe, or economically underdeveloped Eastern Europe, the design and construction methods of prefabricated concrete buildings have been actively promoted. It has accumulated a lot of experience in the design and construction of prefabricated buildings, formed various special prefabricated building systems and standardized general prefabricated product series, and compiled a series of prefabricated concrete engineering standards and application manuals, which have played a role in promoting the application of prefabricated concrete in the world. very important role.

Japan and South Korea have learned from the successful experience of Europe and the United States, on the basis of exploring the standardized design and construction of prefabricated buildings. Combine your own requirements. Breakthrough progress has been made in the overall seismic and isolation design of prefabricated structural systems. A representative achievement is the two 58-story Tokyo Towers built in Japan in 2008 with a prefabricated frame structure. At the same time, Japan's standard specifications for the design, manufacture and construction of precast concrete building systems are also very complete. The currently used precast specifications include "Precast Concrete Engineering" (JASSl0) and "Concrete Curtain Wall) (JASSl4).

my country began to study the design and construction technology of prefabricated concrete buildings from the 1950s and 1960s, and formed a series of prefabricated concrete building systems. The more typical building systems include prefabricated single-story industrial plant building systems and prefabricated multi-storey frame buildings. system, prefabricated slab building system, etc. By the 1980s, the application of prefabricated concrete buildings reached its heyday, and many parts of the country had formed a prefabricated concrete industrialized building model integrating design, production, construction and installation. Prefabricated concrete buildings and masonry buildings with prefabricated hollow floor slabs have become the two most important building systems, with an application penetration rate of over 70%. Due to the many limitations and deficiencies in the functions and physical properties of prefabricated buildings, my country's prefabricated concrete building design and construction technology research and development level has not kept up with the changes in social needs and construction technology development. By the mid-1990s, prefabricated concrete The building has been gradually replaced by the all-in-place concrete building system, except for the prefabricated single-story industrial plant building system, which is widely used. There are very few engineering applications of other prefabricated building systems. The seismic integrity of prefabricated structures and the specialized research on design and construction management are insufficient, resulting in poor technical economy. It is the root cause of the long-term stagnation of prefabricated structures.

The connection nodes of prefabricated concrete require high strength and stiffness, and need to configure a large number of steel bars. However, unlike the cast-in-place concrete structure, the hoisting of large and bulky components and parts is more difficult. Therefore, the connection and avoidance of various steel bars are very important. Otherwise, it will cause difficulties in on-site construction, which will not only increase the man-hours, but also seriously affect the construction quality. In addition, due to the integrity of the old and new concrete, the shear resistance of the connecting nodes is often seriously insufficient. And due to the existence of a large number of steel bars, it is difficult to set a reasonable shear groove, some not only seriously affect the production, but also the effect is not ideal.
