Background technique

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 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, and reducing construction personnel, thereby 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.

The prefabricated assembly structure is to disassemble the traditional cast-in-place wallboard into concrete wallboard components whose shape and size conform to the standard modulus, and then the components are poured and formed in the industrial production workshop, and quickly formed through high-temperature steam curing to reach the standard design concrete strength 80% of the wall is then transported to the construction site, hoisted in place by machinery, and finally the upper and lower wall panels are connected into a whole with grouting sleeves, and the assembled wall structure is formed by connecting horizontally through cast-in-place concrete concealed columns. The prefabricated monolithic structure has been widely used in high-rise prefabricated structures because of its good integrity, high rigidity, and high bearing capacity.

The existing prefabricated concrete wall panels have poor structural connection integrity, resulting in insufficient concrete strength, low life of the wall panels, and hidden dangers in safety.
