High-performance autoclaved aerated concrete integrated board exterior wall structure for prefabricated building

Abstract

The invention relates to a high-performance autoclaved aerated concrete integrated board exterior wall structure for a prefabricated building. The exterior wall structure comprises high-performance autoclaved aerated concrete integrated board bodies and I-type structural steel columns, wherein an iron piece provided with a bolt hole is embedded and welded on a reinforcement main steel bar in the end of each high-performance autoclaved aerated concrete integrated board body, and the overall exterior wall of the prefabricated building is formed by sequential bolted connection and welding of theend parts of the high-performance autoclaved aerated concrete integrated board bodies through steel connectors, the iron pieces and wing plates or web plates in the I-type structural steel columns orI-type structural steel beams. One brand-new connection form of fabricated exterior wallboards is provided for the fabricated exterior wall structure, so that not only can the rigidity of the structure connection be improved greatly, but also properties including energy saving, environmental protection, sound insulation, noise reduction, light weight, high strength, insulation, fireproofing, flameretardance, efficient installation and the like of the exterior wallboards are guaranteed forcefully, and the exterior wall structure has good popularization and application values.

Description

Technical field [0001] The invention relates to the technical field of building structure forms, in particular to a high-performance autoclaved aerated concrete integrated panel exterior wall structure for prefabricated buildings. Background technique [0002] With the development of modern society, people have higher and higher requirements for the energy-saving and environmental protection performance of buildings, which makes autoclaved sand aerated concrete materials with light-weight, energy-saving and environmentally friendly effects more and more used in buildings. In the design of the connecting structure of building exterior walls and exterior wall panels, there has not been a good solution that can achieve good fire insulation effect and good structural rigidity at the joints. Especially in recent years, the exterior wall materials for buildings are different , There are various methods, most of which are on-site assembly of aerated concrete slabs, and common quality pr...

Problems solved by technology

[0002] With the development of modern society, people's requirements for energy-saving and environmental protection performance of buildings are also getting higher and higher, which makes the application of autoclaved sand aerated concrete materials with light energy-saving and environmental protection effects in buildings more and more, but In the design of the connection structure of building exterior walls and exterior wall panels, there has not been a good solution that can achieve good fire insulation effects and good structural rigidity at the joints. Especially in recent years, the materials used for building exterior walls vary There are various methods, most of which are on-site assembly of aerated concrete slabs, and common quality problems such as cracking and leakage of external walls need to be resolved urgently
