low-density pouring glue,better deal with cracks
2020-03-20 16:43:08The reason is that the round steel bar can not form a mechanical tooth key, the long-term anchoring performance of the planted reinforcement can not be guaranteed, and it is easy to leave a hidden danger to the load-bearing structure.There for improve the quality of the project, increase the seismic performance of the house, must be limited to the use of the round steel bars .
2020-03-20 16:48:48The prestressed FRP system is refers to increase the reinforcement materials in the tension zone of strengthening component(or shear weak area).Because of prestressing to improve the stress state of the original beam, bearing capacity and crack strength.
