Abstract

The invention discloses a steel-bonded reinforcement method for a steel structure. The steel-bonded reinforcement method comprises the following steps: marking a bonding range on the predetermined position of a steel structure to be reinforced; cleaning and grinding the surface of the steel structure within the bonding range; bonding the cleaned and grinded prefabricated steel plate within the bonding range by steel bonding glue; pressing and fixing the bonded steel plate to set time. The steel-bonded reinforcement method for the steel structure has the advantages that the construction is convenient, the reinforced steel structure is simple and light, the steel bonding proposals are flexible, and the reinforcement cost is economical and rational.

Description

technical field [0001] The invention relates to a method for repairing a steel structure, in particular to a method for reinforcing a steel structure by sticking steel. Background technique [0002] With the rapid development of the national economy, steel structures are widely used in engineering structures, such as steel structure bridges, steel structure civil buildings, steel structure industrial plants, tower mast structures, etc., and some are used in some special equipment, such as pressure vessels, transportation Pipelines, steel storage tanks and mechanical equipment, etc. [0003] When these steel structures have serious defects and damage or change the service conditions, and the strength, stiffness or stability of the structure does not meet the requirements of use after inspection, there will be potential safety hazards in the structure. In order to prolong the service life of these damaged steel structures and ensure In order to ensure the safety of the struct...
