FIELD: construction.SUBSTANCE: device for strengthening of bearing structures includes a metal shell installed onto a bearing structure and made of vertical angle elements connected to each other by transverse planks, and a spacer device, comprising jacks rested against lower thrust elements as capable of acting at the metal shell in its longitudinal direction via thrust transverse planks rigidly fixed outside on vertical angle elements. The metal shell is stiffly fixed with thrust elements, besides, the device is made as capable of strengthening of the bearing structures area not limited with building structures serving as thrusts, or having a single-sided such limitation. The device is equipped with anchors, with the help of which the upper part of the metal shell and/or the lower thrust elements are fixed to the bearing structure, thrust transverse planks and lower thrust elements are made from angle bar, reinforced with stiffening ribs under jacks, interacting by their upper part with the thrust transverse planks, and at the same time installed directly under the rib of the thrust transverse planks and between ribs of the lower thrust elements, and transverse planks of the metal shell covering the faces of the bearing structure at the side of installation of jacks and thrust transverse planks, are arranged tightly adjacent to the body of the bearing structure.EFFECT: expanded area of device usage for reinforcement of bearing structures.2 cl, 6 dwg |
