The application of common building structural adhesives in the field of reinforcement

Application in adhesive reinforcement

This type of application mainly uses silicone structural adhesive as a bonding material to firmly bond steel plates or profiles for reinforcement, or other reinforcement materials (such as carbon fiber, aramid, and chloroprene) to various reinforced concrete components, such as beams, columns, nodes, bracket panels, tunnels, and arch roofs. The completed reinforcement projects have achieved satisfactory results. Taking beams as an example, they can be ordinary load-bearing beams on buildings, beams for lifting cranes, beams and slabs of highway bridges, reinforced concrete beams of railway bridges, etc. After careful design and construction, the reinforcement and reinforcement effect is very good.

Application in adhesive repair of various buildings

Structural adhesive can also be used to bond and repair various old and ancient buildings (such as wooden structures, concrete structures, stone structures, and brick structures), as well as to repair and repair a certain unit component. The repair process is cumbersome and the repair effect is good, and there are many examples of such applications. In addition, it has been applied for decades in the repair of highway surfaces and airport runways, and the bonding in hydraulic underwater engineering also has broad prospects.

Application in perfusion and repair bonding

It can be applied by pouring adhesive between steel plates and concrete components for external steel reinforcement, and building structural adhesive solidly connects the steel plates and concrete to achieve a joint working effect. It can also be used to seal cracks in ordinary components, ensuring that they meet the original design requirements and avoiding further propagation of cracks. This type of application is also a broad and extensive category, which can be applied not only in building components, but also in various structures such as hydraulic engineering and military engineering for repair and repair.

Application in on-site construction of adhesive components

It has been used in the bonding of the concrete roof of the Sydney Opera House in Australia, and there are also practical examples of column extension and foundation pile extension in China. However, due to the fundamental research on its design theory and calculation method, it is still in the initial stage and is currently in the trial period.
