Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a top-pressing structure in which a masonry wall top is staggeredly connected with a steel beam. Background Art

[0002] In modern construction projects, especially in high-rise buildings and complex structural systems, secondary structure masonry is a vital link, and the setting of structural columns is particularly critical to enhancing the integrity and earthquake resistance of buildings. Traditional construction techniques usually require the layout of formwork around the structural columns and fixation through a formwork system to ensure the accurate shape and size of the concrete when pouring. However, in specific design scenarios, the position of the secondary structure column may be very close to the steel beam structure of the top plate. Due to the narrow distance between the two and the lack of support points, conventional formwork means will make the installation and fixation of the formwork extremely difficult, which greatly increases the construction difficulty and safety hazards of concrete pouring.
