During normal construction; Ring beam and constructional column formwork are generally dismantled in 3 days; Cast-in-place slab and beam formwork will be dismantled in 3 days, and bottom formwork will be dismantled in 15 days, but a point column will be erected every 2 meters. Frame columns are usually dismantled in 7 days. The curing time is usually about 28 days.
Extended data:
Generally speaking, the time to dismantle the concrete side formwork is only to ensure that the surface and edges are not damaged by formwork removal. Under normal circumstances, concrete can be removed after one day. From the actual situation, it is better to dismantle the template as soon as possible.
The bottom die is based on the requirements of GB50204-2002. Generally speaking, in concrete construction, the test blocks with the same conditions will be kept on site, and the pressure test will be carried out when the estimated time is about the same. After the pressure test meets the requirements, it shall be dismantled with the consent of the supervisor (because the form removal inspection lot needs to be filled in, and there is a form removal strength item, so it is required to fill in the form removal test block strength).
