Opening retrofitting

Because there is a window on the wall of the structural drawing, and there is no window in the actual east wall, it is necessary to reopen a window. The design strength of the original wall weakened after the opening. Therefore, it is necessary to reinforce the new openings. The project is reinforced with 300g carbon fiber reinfroced polymer(CFRP) wrap.

Construction sequence

A, drill hole, perforation

Line laying, line inspection -- opening and punching -- large blocks

Externally bonded 300g carbon fiber reinfroced polymer(CFRP) wrap

Laying out -- surface treatment of concrete -- pretreatment of substrate before coating -- coating primer -- carbon fiber wrap -- maintenance -- inspection.
