Reinforcement method

The foundation of basement is to increase the area of foundation and increase the coupling of beams. The method of strengthening shotcrete is applied to the basement and the original structure wall. The floor slab of the original structure is glued with double-layer carbon fiber cloth, and the seam of the foor and slab needs to be seamed.

The basement and the 1-4 floor should be reinforced by steel rebar;

The polymer mortar plastering to the top surface;

Basement, increase of foundation and increase continuous beam;

Library, roof steel stranded wire reinforcement, polymer mortar plastering;

1-4 floor slab surface and cast-in-place laminated construction;

1-4 floor slab construction, bonding and strengthening of carbon fiber at the bottom of the slab.
