Aluminum alloy formwork has the advantages of good mechanical properties, easy installation, high turnover rate, good molding effect, etc., and is currently widely used in the construction of various super-high-rise residential and office buildings. According to relevant architectural design requirements, civil buildings with a building height of more than 100 meters should have a refuge floor. The height and layout of the refuge floor are often different from those of the standard floor. It is usually constructed by combining aluminum and wood (combining aluminum alloy formwork and wood formwork). The flatness control of the junction of the aluminum alloy formwork and the wood formwork, as well as the prevention of slurry leakage during pouring, are the key points for controlling the construction quality of the aluminum-wood connection of the refuge floor.
