In the field of building reinforcement engineering, steel bonding reinforcement is a commonly used reinforcement method.             It pastes steel plates on the surface of concrete structures and uses the bonding force of steel bonding adhesive to make the steel plates and concrete bear forces together, thereby improving the bearing capacity and stiffness of the structure.             To ensure the effect of steel bonding reinforcement, there are strict requirements in all aspects from material selection to construction.             Today, let's take a detailed look:

Detailed introduction and analysis for everyone:

Material selection requirementsSelect qualified structural adhesive for bonding steel.             Structural adhesive is the key material for steel bonding reinforcement, and its performance directly affects the reinforcement effect.             The structural adhesive for bonding steel should have properties such as aging resistance, acid and alkali salt resistance, fatigue resistance and long-term stress resistance, strong impact resistance, strong seismic performance, and good toughness.

The steel bonding adhesive should also have good thixotropy for easy construction and application.             At the same time, the curing time of the structural adhesive should be moderate to meet the requirements of the construction schedule.

When purchasing structural adhesive for bonding steel, check the product inspection report to ensure that its various performance indicators meet the relevant requirements.             At the same time, choose products produced by regular manufacturers to ensure construction quality.

The selection of steel plates in steel bonding reinforcement is also very important.             According to the relevant experience requirements of reinforcement projects, the thickness of steel plates can usually be 4mm or 6mm.             If there is rust on the selected steel plate in steel bonding reinforcement, the rusty part needs to be cleaned up to expose the metallic luster on its surface.             The surface of the treated steel plate should be clean and dry, and there should be no pollutants such as oil stains, water stains and dust.             Because the rusty and unclean surface of the steel plate will affect the bonding strength.

Construction technology

Substrate treatment: Grind the bonding surface to remove the surface layer and loose layer until a new surface is exposed and remove dust.             Clean contaminants with acetone.

Steel plate treatment: Grind the bonding surface of the steel plate until metallic luster appears.             Drill holes in the steel plate at the specified positions according to the design drawings.

Prepare glue: Weigh the SHB-C701 structural adhesive for bonding steel according to the required proportion and fully mix and stir.

Apply glue: Apply the surfaces of the steel plate and the substrate to be bonded with a thickness of 1-3mm, and make the glue thick in the middle and thin around.

Paste the steel plate: After pasting the coated steel plate at the specified position according to the design drawing, immediately fix and pressurize it with chemical anchor bolts or expansion bolts.

Curing and maintenance: Do not move before the glue is cured.             After curing, other operations can be carried out.             During the maintenance period, the bonding condition of the steel plate should be checked regularly.             If there are phenomena such as loosening and cracking, they should be dealt with in time.

SummarySteel bonding reinforcement

Steel bonding reinforcement is a commonly used structural reinforcement method.             Its material selection and construction requirements are directly related to the quality of reinforcement performance.             When carrying out steel bonding reinforcement construction, operations should be carried out in strict accordance with material selection requirements and construction requirements to ensure the quality and safety of reinforcement projects.             At the same time, quality control and inspection of the construction process should be strengthened to discover and solve problems in time to ensure the smooth progress of reinforcement projects.
