Must be strengthened after floor opening

After the opening of the concrete floor, the stress conditions of the concrete floor have changed, and the stiffness and bearing capacity of the floor slab should be reduced. How large holes are opened or not to be reinforced depends on the specific conditions and the size of the function load of the floor

Planting rebar, anchoring reinforcement

Planting rebar is refers to drilling on concrete, wall rock and other substrates, and then injecting high-strength anchoring adhesive. Then insert steel bar or profile, and glue the steel bar and base material into one.It is a more common structural strengthening technology.

CFRP sheet can improve the bearing capacity

Any method of reinforcement is not omnipotent. Carbon fiber retrofitting is carried out on the basis of the original component. The size of the original structure, the reinforcement and the strength of the concrete limit the extent of the function.

Which structure can't be removed in house retrofitting?

The housing structure needs to ensure its overall safety and can not be arbitrarily dismantled and altered. It must undergo strict inspection and appraisal, give detailed consideration to the housing structure, and the final transformation should be carried out under the condition of safety.

Working process of structural strengthening

The main process of structural strengthening is detection and identification - identification results - reinforcement and retrofitting design - reinforcement and retrofitting construction - engineering acceptance
