METHOD FOR BUILDING PRESTRESSED CONCRETE STRUCTURES BY MEANS OF PROFILES CONSISTING OF A SHAPE-MEMORY ALLOY, AND STRUCTURE PRODUCED USING SAID METHOD

摘要

the present invention is a shape memory and a profile consisting of an alloy placed into the concrete, or being the concrete is roughened on the outside to be reinforced, then shaped profile consisting of a memory alloy (2), roughening of the structure the outer is fixed to 9, and for the construction method to be applied to the outer side (9) roughening the cement matrix to cover the profile (2). After the cement matrix is applied, the profile (2) generates a result of the thermal contraction force added, that is tension. Acts as a mortar covering layer 16, the reinforcing layer by mutual coupling of the structure 6 of the roughened outer 9 and the mortar covering layer (16). Profile (2) it is located outside the mortar as a reinforcing layer 16 of the outer structure along the outer side of the structure of the inside of the mortar or the reinforcing layer (16). Structures may also be prepared the prestress introduced in the mortar or the reinforcing layer attached by a heat input, the end of the electric cable (3) are arranged outwardly of the mortar or the reinforcing layer (16) from its end region or electrical cable (3) this area is accessible by removing the insert (5). ;
