GET A QUOTECompared with the 11G101-2 sliding bearing, the stair isolation and anti-collapse rubber bearing has four advantages:
1. Safer — the stairs will not fall off during a major earthquake, and the stairwell will not produce brittle continuous collapse damage during a major earthquake or super earthquake!
2. More beautiful — a "deformation zone" is reserved inside the shock-absorbing support, and the building surface at the connection between the lower end of the stairs and the rest platform can be continuously set as usual.
3. Smaller seismic force — the shock-absorbing support increases the damping ratio of the stairwell, effectively reducing the seismic effect of the stair components.
4. The construction is more convenient — during construction, the isolation bearing is placed between the ladder beam and the ladder plate binding steel bars. After positioning, the whole can be cast in place.
Applications:
It is suitable for reinforced concrete frame structure, frame part of frame-shear wall (core tube) structure and steel frame (support) structure in seismic fortification intensity 6-9 seismic zone.
