Description

Technical Field

[0001] This utility model relates to the field of building structure engineering technology, and in particular to a small-sized opening tool-type lifting formwork for aluminum formwork systems. Background Technology

[0002] With the continuous development of the construction industry, aluminum formwork support systems have been widely used in the construction industry and are one of the evaluation contents of green assessment. However, in the aluminum formwork system, for some small reserved openings ≤200mm, aluminum formwork cannot be processed into hanging formwork, which makes it difficult to reinforce the aluminum-wood combination and hanging formwork at this location, and cannot guarantee the size of the reserved opening and the quality of concrete pouring.
