Project Description

Lift slab

blinding used in lift shafts and stairwells.

Lift-slabs are blindings which are raised phase-wise. Mainly used for lift shafts, stairwells, chutes,…

There are two types of lifting systems:

Lift-slab with clapper:  in this type of blinding one recess of min. 250 mm high and 150 mm wide per clapper must have been provided in the wall during the previous stage. When the lift-slab is raised the 4 clappers will fall and rest into the recesses.

Lift-slab with spring support, in this type of lift-slab one lead-through with M24-wire threaded pipe per spring support must have been provided during the previous stage. The spring support is attached to the wall by means of tensioner and nut. The lift-slab beams rest on these spring supports.
