Description

Technical Field

[0001] The present invention relates to the installation of precast wall panels, and in particular to a method for installing tall and light precast wall panels with combined prevention and control throughout the whole process. Background Art

[0002] In recent years, China has achieved remarkable results in the modernization of the construction industry, and the development momentum of steel structure prefabricated buildings has been getting better and better. The technologies of components such as precast wall panels supporting steel structures have also become more and more mature. Autoclaved aerated concrete roof panels, exterior wall panels, floor slabs, and partition wall panels are collectively referred to as ALC wall panels, which are a kind of tall and light precast wall panels. Reinforcing bars are required for the production of ALC wall panels so that the components can withstand the bending tensile stress generated by bending loads. Due to the porous nature and low alkalinity of autoclaved aerated concrete itself, autoclaved aerated concrete cannot effectively protect the reinforcing bars inside it from corrosion. On the contrary, due to the autoclaved curing process of autoclaved aerated concrete and the easy moisture absorption during use, the reinforcing bars are corroded. Therefore, it is necessary to process the reinforcing bars and their storage. The conventional dipping and drying of steel bar meshes are operated in two devices and steps, with low operation efficiency and high labor costs. Moreover, when the precast wall panels are transported to the construction site and positioned, common ordinary trolleys are likely to cause cracks in the wall panels during the trolleying process. In addition, due to the characteristics of the precast wall panels themselves, conventional rigid installation is likely to cause cracks in the wall panels, affecting the construction quality.

[0003] In summary, it is particularly important to seek a method for installing tall and light precast wall panels with combined prevention and control throughout the whole process, which has high construction efficiency, is simple to operate, and saves costs. Summary of the Invention
