AI Technical Summary
Existing technologies for strengthening by increasing the cross-section have long construction cycles and reduce the usable space inside the building, which cannot meet the owner's requirements for construction period and space.
Angle steel and hoops are used to form an outer steel structure on the surface of the frame beam. Combined with tie rods and column hoops, it is fixed by chemical bolts and welding to form a steel-concrete structure, which enhances the connection strength of the beam-column joint.
This approach strengthens the frame beams, reduces the construction period, avoids encroachment on interior space, and prevents damage to existing walls, thereby enhancing the structural load-bearing capacity.
