Project overview

In accordance with the requirements of Party A, wall and floor openings, with specifications for 300*400mm and 300*700mm, according to experience, combined with site conditions, if the use of manual removal, removal efficiency is relatively low, remove dust, vibration, damage to the original structure, therefore, to ensure the stability of the original structure and meet the guarantee period civilized construction requirements, take the diamond hole cutting program for construction.

According 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.

(Wall and floor openings strengthening)

Structural method

Carbon fiber reinfroced polymer(CFRP) fabric

Structural strengthening materials

HM-30 unidirectional carbon fiber fabric

1.Light self weight,can operate in narrow and small place,not affect the normal use of the building 

2.High strength,can be used in bending,closed hoop and shear strengthening flexibly

3.Flexible,can wrap components with complex shape

4.Suitable for surface of various components(beams,columns,ventilation tube,pipe,wall)

5.Environmental-friendly,anti-acid alkali and other chemical corrosion and rugged environments(have no environmental pollution in themselves)

6.Long shelf life,allow long operational deadline

7.High strength,high modulus

8.Substrates can be the substrates of concrete,masonry structure,wood structure,and many other structure.

9.High temperature resistance,creep resistance under permanent load,corrosion resistance and good seismic resistance performance
