APPARATUS FOR STRENGTHENING THE NEAR-SUPPORT PARTS OF REINFORCED CONCRETE BEAMS

摘要

FIELD: building.;SUBSTANCE: invention relates to building, namely, to strengthening of reinforced concrete beams of the roofing. The apparatus for strengthening the near-support parts of the beams comprises unloading brackets on both sides thereof in the form of a pair of rod elements forming an acute angle. Each end of the rod elements located horizontally is connected with the lower part of the beam, and each end of the rod elements located at an acute angle is connected with the upper part of the beam. The opposite ends of the rod elements are united by supporting plates located on both sides of the beam, and connected by strips installed at the end thereof. The apparatus comprises tensioning tools consisting of a coupling with a stop pin installed on a support, connected with each supporting plate. Additional tensioning tools made in the form of anchors are installed between the rod elements in a mirrored arrangement on both sides of the reinforced concrete beam, connected rigidly with the upper rod element and flexibly with the lower rod element.;EFFECT: increase in the bearing capacity of the near-support parts of the beams.;1 cl, 3 dwg
