COLUMN-MOUNTED SHORING SYSTEMS
Column-mounted shoring system is the term used for formwork panels supported by an up-and-down adjustable bracket jack system attached to already-cast concrete bearing walls or columns. In contrast to traditional formwork systems, this formwork for slabs is supported by several levels of shores and reshores or the ground.
In multistory concrete buildings, the conventional construction method is to build formwork and place concrete for columns, then strip formwork for concrete columns after 12 to 24 hours. Erection of formwork and placing of concrete for slabs proceed after column forms are stripped. Though the newly placed columns have enough strength to support slab loads, they have a limited role in supporting the newly placed concrete slabs. The newly placed concrete slab is typically supported by several levels of shores and reshores. Those levels of shores delay or block the progress of any other construction activities underneath those concrete slabs. As a result, column-mounted shoring systems were developed to employ concrete columns to support formwork for
concrete slabs and thus eliminate any need for shoring and reshoring that may ultimately reduce the overall construction schedule.
