Reinforcement of reinforced concrete surface layer

The supporting formwork is cast in place or sprayed concrete, and a steel mixed layer is added to the outside of the component, reinforcing bars are added to increase the interface of the components.

Significantly improve the bearing capacity, ductility and rigidity, reliable effect, easy to control engineering quality and durability.

The construction period is long, the normal use of structure is restricted, and the wet environment is not good.

Wider range

Reinforcement of reinforced concrete mortar with surface layer

Laying steel bar, fixing the steel mesh and the original components, layered plastering, and maintenance.

It can improve the integrity of components, simple construction, good effect and durability.

The addition of reinforcement is limited and the thickness of reinforcement surface is limited.

Reinforced brick columns, brick walls, etc

Steel jacketing reinforcement

The outer package of the component is reinforced by section steel. According to the use of binder, it can be divided into two types: dry and wet.

The construction is convenient, and the seismic performance can be improved effectively.

Attention should be paid to the rust proof paint on the surface of the steel sleeve, or the surface protection with cement mortar.

It is used to reinforce reinforced concrete beams and columns, brick columns, brick chimneys, etc.

Bond steel plate reinforcement

Using steel plate bonfing adhesive bonding steel plate and original component to improve bearing capacity, crack resistance and ductility of members.

The construction is convenient and fast, and the environmental conditions of the construction site are good.

The steel plate must be protected and the ambient temperature should not exceed 60 C.

General bending and tensile members subjected to static action

The carbon fiber sheet is adhered to the surface of the component with resin high performance composite material to improve the bearing capacity and strength of the structural member.

Carbon fiber elastic modulus and high strength, light weight, small volume, durability and corrosion resistance, easy to construct.

The environment can’t be more than 60 degrees C
