PFEIFER Slab and Stair Support Systems

Application

Provides structural bearing points on supporting beams for double-T and trough floor slabs.

Description

PFEIFER PS-A Steel Bearings provide structural bearing points on supporting beams for double-T and trough floor slabs. They are cast into the precast floor unit to provide both temporary bearing points for the floor during construction and permanent bearing after construction is completed. They support dead weight loads during assembly without the need for temporary propping. After a reinforced concrete topping is applied to the floor live loads can also be transferred to the floor's support beams via the PFEIFER PS-A Steel Bearings.

PFEIFER offers two staircase bearing products. PFEIFER Intermediate Staircase Bearing VarioSonic SL is intended for use as an intermediate support for absorbing vibration while also transferring vertical and resultant loads from the stair unit to the stairwell walls. PFEIFER Staircase Bearing SLE is normally used to transfer loads to the landing or floor. Both systems are vertically adjustable allowing the stair unit to be easily levelled and accommodate any construction tolerances.

  • Fire resistance of R90.

- PFEIFER PS-A Steel Bearings:

  • Secure bearing to structural beams.
  • Direct bearing with low load eccentricity.
  • Replaces concrete corbels and locating bolts.
  • Saves construction costs and time.
  • Cast into the precast components under controlled conditions.
  • Saves time in construction and design.
  • Screeding is no longer essential after concreting the slab topping.
