Split Level Protection

Split level protection is to prevent vehicles and pedestrians falling through the open spaces in between floor levels. Any drop greater than 380mm needs to be protected and a simple barrier system is the minimum requirement. A pedestrian mesh infill system is also recommended with the mesh meeting the 100mm sphere ruling from BS 6180. Lighter weight systems can generally be used taking advantage of the free space behind for barrier deflection and to minimise incursion into the parking bay lengths. Typical examples include, but are not limited to:

• RB1 Buffer Detail with Berry Beam	RB1 Spring Steel Steel Buffer with Barrier Rail, Handrail and Mesh infill.

  Max Post Centres: 1600mm Barrier Rail 1500mm Berry Beam
  
  Special height buffers can be custom made to suit the opening.
  
  No of fixing bolts: 1
  
  The RB1 buffer has a small footprint (only 200mm) in the parking bay and overall parking length is only reduced by the 100mm depth of the barrier. Sufficient free space must be available behind for barrier deflection. Up to 550mm should be allowed although most impacts will result in deflection much less than this.
  
  

• RB1X Buffer Detail with Berry Beam	RB1X Spring Steel Steel Buffer with Barrier Rail, Handrail and Mesh infill.

  Mesh can be added to suit approriate split level openings if required.
  
  No of fixing bolts: 1
  
  The RB1X is designed to reduce deflection while minimising the incursion onto the parking bay. It is ideal where a structure behind the barrier needs to be protected as well.
  
  

• GH Buffer Detail with Berry Beam	RB1X Spring Steel Steel Buffer with Berry Beaml, Handrail and Mesh infill.

  Max Post Centres: 1600mm Barrier Rail
  1500mm Berry Beam
  
  Mesh can be added to suit approriate split level openings if required.
  
  No of fixing bolts: 2
  
  The strongest of the split level solutions but has a larger footprint. Deflection is contained with the depth of the system providing excellent protection for any structures behind.
  
  NB. Mesh infill can be added to any of the above systems to suit specific split level openings if required.
