The main reinforcement methods of civil buildings?

There are a variety of ways to reinforce building, but mainly from two aspects, one is retrofitting to the damaged and the other is up to a certain resistance to abuse such as seismic retrofitting

First, the foundation reinforcement:


(1) Reinforcement of foundation by grouting: It is applicable to reinforce foundation on the basis of uneven settlement due to stress, frost heaving or other reasons.


(2) To increase the basis of the bottom area: It is applicable to reinforce existing buildings when the foundation bearing capacity or foundation area size does not meet the design requirements.


(3) Anchor Static Pressure Pile: It is suitable for foundation soil consolidation and rectification and consolidation of silt, muddy soil, cohesive soil, silt and artificial soil.


(4) Root reinforcement: It is suitable for foundation soil consolidation and rectification and consolidation of silt, muddy soil, cohesive soil, silt and artificial soil.



Second, the column strengthening:


(1) Reinforcement of concrete enclosure: It is suitable for reinforcement when the cross-section flexural capacity and shear capacity are not enough.


(2) Epoxy bonded steel plate: applies to the serious lack of capacity when the cross-section, and does not allow to increase the cross-section reinforcement.



Third, the wall reinforcement:


(1) Mortar surface reinforcement: suitable for carrying capacity of similar static reinforcement and seismic reinforcement.


(2) Reinforced mesh mortar surface reinforcement: suitable for static reinforcement and high strength seismic reinforcement.


(3) Reinforcement of reinforced concrete wall: apply to a larger increase of static reinforcement and seismic reinforcement.



Fourth, the beam strengthening:


(1) Steel jacketing, epoxy bonded steel plate reinforcement.


(2) The use of carbon fiber fabric, carbon fiber reinforced polymer laminate(CFRP laminate/strip/plate).


(3) The use of increased cross-section reinforcement.



Fifth, the slab reinforcement:


(1) Steel jacketing, epoxy bonded steel plate reinforcement.


(2) The use of carbon fiber fabric, carbon fiber reinforced polymer laminate(CFRP laminate/strip/plate).



Six, the balcony strengthening:


(1) Steel jacketing, epoxy bonded steel plate reinforcement.


(2) The use of carbon fiber fabric, carbon fiber reinforced polymer laminate(CFRP laminate/strip/plate).



Seven, anchoring anchor:


Suitable for adding new columns, add more wall, new floor and hole sealing.



Eight, curtain wall strengthening


For curtain wall and steel structure base parts, fence installation.
