Description

Technical Field

[0001] The invention relates to a prefabricated wall panel installation, and in particular to a method for installing a tall and lightweight prefabricated wall panel with combined prevention and control throughout the entire process. Background Art

[0002] In recent years, my country has made remarkable achievements in the modernization of the construction industry, among which the development momentum of steel structure prefabricated buildings is getting better and better. The technology of prefabricated wall panels and other parts matching steel structures is also becoming more and more mature. Autoclaved aerated concrete roof panels, exterior wall panels, floor panels, and partition panels are referred to as ALC wall panels, which are tall and lightweight prefabricated wall panels. Rebars are required to produce ALC wall panels so that the components can withstand the bending tensile stress generated by bending loads. Due to the porosity and low alkalinity of autoclaved aerated concrete itself, autoclaved aerated concrete cannot effectively protect the steel bars inside it from rusting. On the contrary, due to the autoclaving curing process and easy moisture absorption during the use of autoclaved aerated concrete, the steel bars are corroded. Therefore, the steel bars and their storage must be processed. Conventional steel mesh dipping and drying are divided into two devices and steps, with low operating efficiency and high labor costs. Moreover, when the prefabricated wall panels are transported to the construction site, the commonly used ordinary carts are prone to cause wall panel collisions and cracks during the carting process. In addition, due to the inherent characteristics of prefabricated wall panels, conventional rigid installation can easily cause cracks in the wall panels, affecting construction quality.
