Formwork for forming high thickness concrete shear wall of building, has side walls defining space that is provided with filtering elements, where elements define inner volume separated from space by filtering wall permeable to water

摘要

The formwork has two side walls (1, 2) connected together by connection elements (3, 4), where the walls (1, 2) define a space to be filled with a mixture of concrete and water. The space includes circular shaped inner filtering elements (6) defining an inner volume that is not intended to be filled with concrete and is separated from the space by a filtering wall (7) permeable to the water. The element provides a steel thread supporting outside the filtering wall.
