Description

Prefabricated concrete overall without thermal bridge corner plate

technical field

The invention belongs to the technical field of buildings, in particular to a prefabricated concrete integral heat-free corner plate.

Background technique

Prefabricated concrete buildings refer to prefabricated concrete components produced in factories. Concrete structure housing buildings designed and constructed through on-site assembly. At present, the assembly methods of components generally include on-site post-casting laminated concrete, steel bar anchoring and post-casting concrete connection, etc. The steel bar connection can be connected by sleeve grouting, welding, mechanical connection and lap connection with reserved holes. In the 1980s, prefabricated prefabricated large-slab houses, which were popular in my country, had many hidden dangers and defects that affected structural safety and normal use due to poor structural integrity, leakage, and floor cracks, and were gradually replaced by on-site concrete structures. , but with the current emerging application of prefabricated concrete structures, especially the introduction of many foreign advanced technologies in recent years, domestic new technologies for the construction of prefabricated concrete structures are gradually taking shape.

With the acceleration of the process of "construction industrialization and housing industrialization" in China, the continuous reduction of China's "demographic dividend" and the emergence of labor shortages in the construction industry, the trend of industrialization of housing industry is becoming more and more 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 my country's building structure. It is conducive to the development of my country's building industrialization, improving production efficiency and saving energy, developing green and environmentally friendly buildings, and is conducive to improving and ensuring 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 Reduce noise, prevent dust, reduce environmental pollution, clean transportation, reduce site disturbance, save water, electricity, materials and other resources and energy, and follow the principles of sustainable development. Moreover, the prefabricated structure can continuously complete multiple or all processes of the project in sequence, thereby reducing the types and quantities of construction machinery entering the site, eliminating the idle time between process connections, realizing three-dimensional cross operations, reducing construction personnel, and improving work efficiency , Reduce material consumption, reduce environmental pollution, and provide guarantee for green construction. In addition, the prefabricated structure can reduce construction waste to a large extent (accounting for about 30%-40% of the total urban waste), such as waste steel bars, waste iron wires, waste bamboo wood, waste concrete, etc.

Prefabricated concrete buildings can be divided into two categories: full assembly and partial assembly according to the degree of assembly. Fully assembled buildings are generally limited to low-rise or multi-storey buildings with low seismic fortification requirements; the main components of partially assembled concrete buildings are generally prefabricated components, which are connected by cast-in-place concrete on site to form a building with an assembled monolithic structure.

North America is mainly dominated by the United States and Canada. Due to the long-term research and promotion of precast buildings by the Precast/Prestressed Concrete Association (PCI), the relevant standards and specifications for precast concrete are also very complete. Therefore, its prefabricated concrete buildings are widely used; 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. It can optimize the structural reinforcement and connection structure, 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-seismic fortified areas. Due to the impact of earthquakes in the California area, in recent years, great attention has been paid to the research on engineering application technology of earthquake resistance and mid-high-rise prefabricated structures. PCI recently published the book "Seismic Design of Prefabricated Concrete Structures", which systematically analyzes the seismic design of prefabricated buildings from the perspective of theory and practice, and summarizes the latest scientific research achievements in the seismic design of prefabricated structures. Promotion has a strong guiding significance.

Europe is the birthplace of prefabricated buildings, and the road to industrialization of buildings began as early as the 17th century. After the Second World War, due to the shortage of labor resources, Europe further studied and explored the industrialization model of construction. Whether it is economically developed Northern Europe, Western Europe, or economically underdeveloped Eastern Europe, they have been actively promoting the design and construction of prefabricated concrete buildings. 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 precast concrete engineering standards and application manuals, which played a role in promoting the application of precast concrete in the world very important role.

Drawing on the successful experience of Europe and the United States, Japan and South Korea have made breakthroughs in the overall seismic and isolation design of prefabricated structural systems on the basis of exploring the standardized design and construction of prefabricated buildings and combining their own requirements. Representative achievements are the two 58-story Tokyo Towers built in Japan in 2008 using prefabricated frame structures. At the same time, the standard specifications for the design, production and construction of precast concrete building systems in Japan are also very complete. The prefabricated specifications currently in use include "Precast Concrete Engineering" (JASSl0) and "Concrete Curtain Wall) (JASSl4).

my country began to study the design and construction technology of prefabricated concrete buildings in the 1950s and 1960s, and formed a series of prefabricated concrete building systems. The more typical building systems include prefabricated single-storey 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 have formed a prefabricated concrete industrialized building model integrating design, production, construction and installation. Prefabricated concrete buildings and masonry buildings with prefabricated hollow-core 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, the level of design and construction technology research and development of prefabricated concrete buildings in China has not kept up with the changes in social needs and the development of construction technology. By the mid-1990s, prefabricated concrete Buildings have been gradually replaced by all-cast-in-place concrete building systems. At present, 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. Insufficient research on the integrity of seismic resistance of prefabricated structures and specialized research on design and construction management have resulted in poor technical and economical performance, resulting in long-term stagnation of prefabricated structures. For this reason, it is necessary to carry out industrialized and systematic research and development aimed at the shortcomings of poor mechanical performance and poor seismic performance of existing buildings, so that my country's construction industry can truly realize the green, recyclable and sustainable process of the whole process.
