Title:
METHOD OF STRENGTHENING REINFORCED CONCRETE STRUCTURES (VARIANTS)
Document Type and Number:
WIPO Patent Application WO/1997/012102
Kind Code:
A1
Abstract:
The proposed method of strengthening reinforced concrete structures pertains to construction and improves resistance to splitting, breaking and bursting of reinforced concrete structures. It can be implemented in either of two variants. In the first variant involving the use of reinforcing and concreting elements in formwork, the reinforcing and concreting elements used are a longitudinal and a transverse helical element in a free untensioned state; transverse spirals are fitted in the windings of the longitudinal helical element, the axes of the longitudinal and transverse helical elements are aligned to be mutually perpendicular, and are then spaced evenly and secured throughout the volume of the three-dimensional casing of the reinforced concrete structure, or alternatively the casing is formed from a three-dimensional helical matrix, the three-dimensional casing is concreted to create conditions under which when any stretching forces are applied in any direction reinforcement is produced which is perpendicular to the planes of the principal forces. In the second variant involving the use of reinforcing and concreting elements in formwork, the reinforcing elements used are a lamellar element with projections in a free untensioned state, and concreting is done to create conditions for moulding the casing of the reinforced concrete structure from the lamellar element.
