Patent attributes
The present invention provides a multi-storey modular building including at least a first and a second lightweight concrete-based prefabricated modules each having at least a beam, a column, and one horizontal structure selected from a ceiling or a floor at least partially attached to two or more of the beams and columns. A connection system includes at least one vertical alignment connector attached to a horizontal load-distributing plate positioned between the first and second lightweight concrete-based prefabricated modules for connecting the first and second lightweight concrete-based prefabricated modules, where a top portion thereof is positioned in a grout accepting cavity in the bottom end of the column of the second lightweight concrete-based prefabricated module and that in the top end of the column of the first lightweight concrete-based prefabricated module. In-situ grout embeds the vertical alignment connector in each grout accepting cavity.
