technical field

The utility model relates to a building energy-saving wall body, in particular to a fast-installation load-bearing heat-preservation and decorative integrated composite board adopted in an energy-saving building.

Background technique

Prefabricated concrete buildings refer to concrete structure buildings designed and constructed through on-site assembly, mainly based on factory-produced concrete prefabricated components. The assembly methods of components generally include on-site post-casting laminated layer concrete, steel bar anchoring and post-casting concrete connection, etc. The steel bar connection can be connected by sleeve grouting connection, welding, mechanical connection and lap connection of 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 cast-in-place concrete structures. . However, with the current emerging application of 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 forming.

With the acceleration of the process of "construction industrialization and housing industrialization" in my country, and the continuous reduction of China's "demographic dividend", the labor shortage in the construction industry has emerged, and the trend of housing industrialization has become increasingly obvious. The application of prefabricated concrete structures has become a current research hotspot again, and 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 reducing noise, preventing dust, reducing environmental pollution, clean transportation, reducing site disturbance, saving water, electricity, materials and other resources and energy, and following 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 prefabricated buildings by the Prefabricated / Prestressed Concrete Association (PCI), the relevant standards and specifications of precast concrete are also very complete, so 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 structures, which can optimize structural reinforcement and connection structures. 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 has recently published the book "Seismic Design of Precast 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.

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, combined with their own requirements, they have made breakthroughs in the overall seismic and isolation design of prefabricated structural systems. The representative achievement is Japan. In 2008, two 58-story Tokyo Towers were built 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 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, my country's prefabricated concrete building design and construction technology research and development level cannot keep up with social needs and changes in the development of construction technology. By the mid-1990s, prefabricated concrete buildings had been gradually replaced by all-cast-in-place concrete building systems. At present, except for the widely used prefabricated single-storey industrial plant building systems, other prefabricated prefabricated building systems have very few engineering applications. Insufficient research on structural seismic integrity and professional design and construction management results in poor technical and economic efficiency, which is the fundamental reason for the long-term stagnation of prefabricated structures.

At present, prefabricated concrete structures are all wet construction, the construction process is complicated, the cost is high, and due to the high density of the wall, the wall panels cannot be prefabricated to a large size, otherwise a series of problems will be encountered in processing, transportation and hoisting engineering; Due to the existence of the insulation layer, the integrity of the wall sheet will be significantly reduced regardless of the setting of internal insulation, sandwich insulation or external insulation; in addition, the connection method is more complicated, and the on-site operation encounters more difficulties, and the construction period is increased, and the cost is significant. promote.
