Abstract

The invention relates to a concrete structure reinforcing method, a self-anchored prestress assembly and an assembled tensioning assembly. The concrete structure reinforcing method comprises the following steps including: an anchor seat installation step: an anchor seat is fixed on a concrete structure, wherein the anchor seat is pasted by adopting a pouring method, and fastening elements are chemically buried; a prestress cable manufacturing and installation step: a prestress cable is manufactured and is arranged in the assembled tensioning assembly; a prestress tensioning step: the prestress tensioning step includes a single prestress cable pre-tensioning sub step and a whole prestress cable tensioning sub step, so that the single prestress cables can be sequentially tensioned, and all of the prestress cables can be subsequently tensioned integrally; and a mortar spraying reinforcing step: the mortar spraying is at least carried out on regions covered by the prestress cables of the concrete structure, so that the reinforcement on the concrete structure is realized. The invention aims at providing the method of obviously improving the bearing force of the concrete structure.

Description

technical field [0001] The invention relates to a method for strengthening a concrete structure, a self-anchor prestressed component used for the method for strengthening the concrete structure, and an assembled tension component for the method for strengthening the concrete structure. Background technique [0002] At present, concrete structures are widely used in various facilities, but some concrete structures that have been built have insufficient bearing capacity and need further reinforcement to meet the bearing requirements. For example, as the economy develops, the traffic volume increases, and the load class changes. Therefore, with the above-mentioned development, the bridges that have been built urgently need to be reinforced to meet the current load-bearing requirements. Commonly used bridge reinforcement methods include enlarging section reinforcement method, pasting steel plate reinforcement method, pasting carbon fiber reinforcement method, concrete crack sea...
