Abstract
A method of constructing a poured concrete structure protected from corrosive agents includes applying large-surface sealing elements to one surface of the structure before pouring the concrete. The sealing elements are attached to anchoring elements extending into a region into which concrete is to be poured. When the concrete is poured inside the sealing elements, the sealing elements are anchored in place by the anchoring elements which become set in the concrete. The sealing elements may have a high modulus of elasticity and be relatively rigidly affixed to the structure of may have a low modulus of elasticity and thus require overlapping perimeter areas for sealing of adjacent sealing elements.
Claims10
A method of constructing a poured concrete structure protected from corrosive agents comprising the steps of:
- applying large surface sealing elements supported by a formwork and defining at least one surface having a component in an upright direction of said concrete structure before pouring said concrete;
- overlapping perimeter areas of adjacent sealing elements to provide protection to the concrete from liquids flowing under gravity forces;
- providing anchoring elements on said sealing elements extending into a region into which concrete for said structure is to be poured;
- attaching climbing rails for a climbing formwork to said anchoring elements;
- applying a sealing strip having a high modulus of elasticity and great resistance to corrosion in a region of said climbing rails;
- pouring said concrete inside said sealing elements and said formwork;
- and
- setting said concrete whereby said sealing elements become anchored to said structure by said anchoring elements in set concrete whereby said climbing formwork is movable on said rails to another higher position.
