Earthquake Strengthening of School Column

Project overview

Due to the lack of aseismic grade, primary school buildings need seismic reinforcement by steel angle and carbon fiber reinfroced polymer(CFRP) wrap.

1.Beams and columns of carbon fiber reinforcement

2.Columns reinforced by angle steel

2.1, all steel components are made of Q235B steel and the welding rod should conform to the corresponding design specifications. 

2.2, all perfusion structural adhesive are used a structural adhesive. 

2.3, other parts of the self leveling and grouting material for filling.  

2.4, all column reinforcement is reinforced from the bottom up, strictly according to the reinforcement from bottom to top.

Structural strengthening materials

1. Q235B steel
   

2. Carbon fiber fabric

3. Steel plate bonding adhesive

4. Perfusion steel plate adhesive
