In the absence of changing the original structure, it is decided to reinforce the column,beam and slab with carbon fiber reinfroced polymer (CFRP).
2020-03-23 13:05:23The difficulty of the old building reinforcement and retrofitting:1. Short construction period;2. Many obstacles of strengthening design;3. More difficulty in construction;4. High security requirements
2020-03-23 12:57:44The building should be reinforced and retrofitting into industrial factory building of the first and thecond level, and third to five floors for the office building.A large amount of reinforcement and repair construction of the foundation, column, beam, plate and other components which are not satisfied with the requirements of standard and safe are carried out.
2020-03-23 12:56:15According to the requirements of the standard, the reinforcement of the concrete structure should be strengthened when the opening of the concrete structure is more than 300*300mm. In order to ensure the stability of the original structure, the shear wall and floor of this project are 300*400mm and 400*700mm, which should be strengthened according to the requirements of the standard.
2020-03-23 11:31:04Under the three circumstances, it is necessary to reinforce the slab: the bearing capacity of the slab is insufficient; the strength of the floor slab is unqualified; the slab is opening.
2020-03-23 11:30:00The original structure can not meet the needs of the present stage, so it needs to change the use function of the building. In the case of ensuring the safety of the building, it is decided to dismantle a part of the load-bearing wall so that the building can be connected through space to form a whole. Based on the above reasons, the original building structure should be strengthened.
