Abstract

The invention discloses a method for reinforcing a concrete weak beam. The method is characterized in that negative reinforcements are arranged at the upper part of a concrete beam; the diameter of each negative reinforcement is 22-25 mm; two main reinforcements are arranged at the lower part of the concrete beam; the diameter of each main reinforcement is 22-25 mm; a groove is formed in the lower part of the concrete beam; the groove is 50-60 mm in depth and 70-80 mm in width and length; steel reinforcement horse-shaped stools are anchored into the groove; the groove is filled with high-strength epoxy resin mortar; the diameter of each steel reinforcement horse-shaped stool is 28 mm; the steel reinforcement horse-shaped stools are welded with stirrups; the space between the steel reinforcement horse-shaped stools is 500-550 mm; a reinforcement body is arranged at the lower part of the concrete beam; the reinforcement body adopts expanded concrete; a steel supporting plate is arranged at the lower part of the reinforcement body; a steel cover plate is arranged at the upper part of the concrete beam; the steel cover plate is connected with the steel supporting plate by prestressed supporting rods; sprayed concrete is arranged at the peripheries of the steel supporting plate and the prestressed supporting rods after prestress tension; and the sprayed concrete is 30-40 mm in thickness and C30 in strength.

Description

technical field [0001] The invention relates to a layer-added component, in particular to a reinforcement method for a concrete sick beam. Background technique [0002] In actual engineering, due to reasons such as poor design, poor construction quality, and poor construction site management, the bearing capacity of the flexural members of reinforced concrete beams is insufficient. Reduced strength and more. The purpose of strengthening concrete sick beams is to achieve repair, reinforcement, increase bearing capacity, enhance use functions, and meet service requirements through reinforcement construction. Therefore, it is particularly important to strengthen concrete sick beams with reasonable and reliable structural forms. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a method for reinforcing a concrete sick beam with good safety performance. [0004] The reinforcement structure of the concrete sick beam in the pre...
