What are the commonly used steel structure reinforcement engineering technologies?

        1.Bonded steel reinforcement

It is suitable for bending, shear, tension and compression reinforcement of beam, slab and column members mainly subject to static force.When it is used for the reinforcement of compression and large dynamic components, additional anchoring methods shall be added; for example, two planting bolt or through beam and through plate split bolt anchoring shall be set every 100mm.The strength grade of the reinforced component concrete shall not be lower than C15.

 

  2.Bonded carbon fiber reinforcement

It is suitable for beam, slab and column to be strengthened by bending, shearing, tension and compression, and it is suitable for receiving the reinforcement of dynamic components and curved components.When the reinforced members are used for compression members, they shall be enclosed and pasted, and the concrete strength grade of the reinforced members shall not be lower than C15.

 

  3.External steel reinforcement

The scope of application is the same as that of (6.1), which is used for the members that need to greatly improve the bearing capacity.

 

  4.Chemical planting

It is applicable to the connection and extension of reinforced concrete structure and other components, or the addition of stressed steel bars.When the base material is plain concrete or rock, the anchorage length of planting reinforcement shall be determined by special experiment.The strength grade of base material concrete shall not be lower than C20.

 

  5.Chemical bolt

It is applicable to the anchoring of non structural members, non main members, appliances and concrete (such as the fixation of air conditioning pipes and equipment bases).The strength grade of base material concrete shall not be lower than C20.

 

  6.Crack chemical grouting reinforcement

It is suitable for recovering the integrity and application function of cracked components and blocking the erosion of concrete and steel bars by other media.

 

  7.Structural adhesive repair and reinforcement

It is suitable for repairing the holes, pits and sections of concrete and masonry components.

 

  8.Pre-stressed reinforcement

It is suitable for beam, slab and column to be strengthened by bending, tension and compression, with less stress lag and good cooperation.

 

  9.Increase section reinforcement

It is applicable to structures that are insensitive to self weight addition and appearance change.

 

  10.Add support and reinforcement

It is applicable to structures with low requirements for space use and vision.
