Thermal-bridge-free aerated concrete wallboard

Abstract

The invention belongs to the technical field of building, and particularly relates to a thermal-bridge-free aerated concrete wallboard. The thermal-bridge-free aerated concrete wallboard has the beneficial effects that arranged stirrup connecting pieces provide uniform lateral pressure and effective constraint to concrete, inner row embedded column area connecting rebars, middle row connecting rebars and outer row embedded column area connecting rebars are arranged in an auxiliary mode, and a complete and multi-level restraint system is formed, it is ensured that whole slipping or deformationduring bearing of the wallboard are avoided, the self stability ability and the whole anti-slipping and anti-overturning ability of the wallboard are improved, damage caused by friction between concrete layers is prevented though a first friction-reducing layer and a second friction-reducing layer, the self-weight of the wallboard is reduced by adopting the aerated concrete, the structural ductility and energy dissipation ability are improved, and the seismic performance is further improved. According to the thermal-bridge-free aerated concrete wallboard, the overall synergistic performance isgood, the steel consumption amount is small, energy consumption is reduced, the whole thermal-bridge-free technology and a reinforced embedded column system are adopted, a thermal bridge can be effectively cut off, the heat insulation effect of the wallboard is improved, the seismic ability is ensured, and meanwhile, the thermal bridge in the wallboard is eliminated.

Description

technical field [0001] The invention belongs to the technical field of buildings, in particular to a thermal bridge-free aerated concrete wall panel. Background technique [0002] 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.

Problems solved by technology

In the 20th century, prefabricated buildings in North America were mainly used in low-rise non-seismic fortification areas. Due to the impact of earthquakes in California, in recent years, great attention has been paid to the engineering application technology research of earthquake resistance and mid-high-rise prefabricated structures to protect the main structure and components from strong earthquakes. In the industry, the method of increasing the thickness of the concrete wall is used to improve the above situation, but this not only increases the amount of concrete, but also increases the construction strength and cost, and the key point is that the seismic force is proportional to the self-weight of the wall, and the weight increases with the weight of the wall. As the thickness increases, the horizontal shear force generated by the earthquake also increases, so the horizontal shear resistance effect of the wall, that is, the horizontal bearing capacity, is still not ideal. The edge members of the traditional shear wall have the problem of too large reinforcement. Under the action of earthquake load, the ductility of the shear wall is insufficient, the energy dissipation capacity is poor, and its design and construction are more complicated. Therefore, it is necessary to carry out industrialized systematic research on the shortcomings of existing buildings, such as poor mechanical performance and poor seismic performance. The research and development of China's construction industry has truly realized the green, recyclable and sustainable process of the whole process.
