Abstract

1. ARMATURE PRE-STRESSED ELEMENT, containing a pipe, a core housed in it, end and intermediate anchors, characterized in that, in order to increase its adhesion to concrete, the intermediate anchors are made in the form of annular linings periodically arranged along the length of the pipe and fixed with a gap relative to its surface. 2. A reinforcing element according to claim 1, characterized in that the annular linings are elliptical in shape, the size of the minor axis of which is equal to the outer diameter of the pipe.

I: HM (LB) COKOi pOCHNY The material of the pipe is in compression and thereby increase its calculated compressive resistance for the limiting states of the first group and, accordingly, reduce the consumption of reinforcement. When using a reinforcing element in a compressed zone of bent reinforced concrete structures, the force in a pre-compressed pipe creates a moment of internal forces in the direction opposite to the moment of external forces. As a result, the characteristics of crack resistance and deformability of the bent structure are improved.

Claims (2)

1. A reinforcing pre-stressed element containing a pipe, a core placed in it, end and intermediate anchors, characterized in that, in order to increase its adhesion to concrete, intermediate anchors are made in the form of annular overlays periodically located along the length of the pipe and fixed with a gap relative to its surface. 2. Reinforcing element in π. 1, characterized in that the annular lining is made of elliptical shape, the size of the minor axis of which is equal to the outer diameter of the pipe.
