Embodiment 1
[0060] Such as Figure 1-4 , Picture 9 As shown, this embodiment provides the use of embedded wet-bonded FRP strips for bending reinforcement of the reinforced concrete structure 1, and the implementation steps include:
[0061] (1) A trench 2 is opened on the bottom surface of the concrete structure 1 to be reinforced. The trench 2 has a depth of 25 mm and a width of 12 mm. (2) Rinse the groove 2 with high-pressure water, and after the groove 2 is left to dry for at least one day, blow it with an air pump with a pressure of about 1.7 MPa to ensure that the groove 2 is clean and dry. (3) Use a glue gun to inject the adhesive into the groove 2, and the dosage is limited to a slight overflow of the groove. (4) Brush the surface of the FRP strip 3 with an adhesive that is the same as or compatible with the adhesive poured in the groove 2 and make it brush to fully wet the FRP strip 3. (5) Except for anchoring or adapting to the surface shape of the structure, the FRP strip 3 shoul...
Embodiment 2
[0063] Such as Figure 5-8 , Picture 9 As shown, this embodiment provides the use of embedded wet-bonded FRP strips for shear reinforcement of the reinforced concrete structure 1, and the implementation steps include:
[0064] (1) A number of trenches 2 are opened on the surface (including the ground, top and side surfaces) of the concrete structure 1 to be reinforced. The trenches 2 are 25mm deep and 12mm wide. The bottom trenches 2 or When the top groove 2 transitions to the side groove 2, a circular arc with a radius of 25 mm is used for transition. (2) Rinse the groove 2 with high-pressure water, and blow the groove 2 with an air pump with an air pressure of about 1.7 MPa after being dried for at least one day to ensure that the groove 2 is clean and dry. (3) Use a glue gun to inject the adhesive into the groove 2, and the dosage is limited to a slight overflow of the groove. (4) Brush the surface of the FRP strip 3 with an infiltrating adhesive that is the same as or compa...
Embodiment 3
[0066] This embodiment provides a component obtained by using the reinforcement method of the first embodiment. Such as Figure 1-4 , Picture 9 As shown, it includes a concrete structure 1 and an FRP strip 3. A groove 2 is provided on the surface of the concrete structure 1. The groove 2 is embedded with an FRP strip 3, and the FRP strip 3 is bonded The agent is embedded in the groove 1, the FRP strip 3 is woven from long fiber filaments, and the cross section of the FRP strip 3 is rectangular. Among them, the concrete structure 1 has a clear span of 4000 mm, a cross-sectional height of 450 mm, and a cross-sectional width of 200 mm. The FRP strip 3 has a thickness of 4 mm and a width of 25 mm, and the groove 2 has a width of 12 mm.
