What is the reinforcement of building structure, and what are the ways?

There are many structural reinforcement methods, such as:

Auxiliary reinforcement:

Reinforcement planting technology, also known as reinforcement rooting technology, is to drill holes in the original concrete structure, inject structural glue, and insert new reinforcement into the holes by rotation. This technology is widely used in design changes, adding beams, columns, cantilever beams, slabs and other reinforcement and change projects.

Sticking steel:

The original design bearing capacity and failure resistance of reinforced concrete structural members strengthened with steel plates can be greatly improved after they are bonded with adhesives.

Steel bar:

Baotou steel reinforcement is also called bonded steel reinforcement method, and reinforced concrete beam-column reinforcement is called Baotou steel reinforcement. When glued with latex cement or chemically grouted with epoxy resin, it is called wet ladle reinforcement.

Structural underpinning: structural underpinning technology refers to the functional transformation of the original load-bearing structure that affects the use function of the building by changing the stress system, with the aim of obtaining more ideal use space.

Enlarging cross-section: Enlarging cross-section reinforcement technology, also known as concrete reinforcement technology, is to increase the cross-section and reinforcement of members to improve their strength, stiffness, stability and crack resistance, and can also be used to repair cracks. This reinforcement technology has a wide range of applications, and can reinforce plates, beams, columns, foundations and roof trusses.
