Technical documentation
Benefits
- Provides noise decoupling between stair landings and structure
- Simple and straightforward to use
- Especially suited to pre-cast concrete landings
Applications
- The HBB HALFEN bi-Trapez-Box is used as a point-load support for staircase landing slabs. The load transmission is via elastomer supports. The landing-slabs are monolithically connected with the building in this case. The impact sound insulation is placed between the landing-slab and the staircase. The units can be used both with cast on-site concrete or precast elements together with concrete or masonry walls.
