There is security for an engineer to know that the principal reinforcement in the structural elements has been fixed in the right place in the factory, rather than be subject to the hazards of a building site where incorrect steel fixing, poor cover control, poor placing of concrete, etc. are every day occurrences

 The structural elements of the Cobute staircase

The structural elements of the Cobute staircase

The elements of the Cobute precast slab ( panels and ribs) and beam system allow for manufacturing of a precast permanent shuttering for staircases, along with the use of precast risers and treads. The Cobute staircase is modular and has no measurement constraints, satisfying any job specifications, many shapes (such as dog-leg, U and L shaped among many more) and landings, except for the round ones. As per the all the Cobute Precast slab and beam systems, only minimal shuttering is required.

 

 

Installation of the Cobute Staircase

The Cobute stair consists of 5 elements, light to handle and easy to install on site. The left and right girders form the R.C. frame of the element, which is then filled by precast ribs and panels. Before casting, risers are installed. Each staircase is custom- made according to the job requirements; a straight flight of stairs can be installed, ready for casting, in roughly 2 hours by 4 labourers

 

Why choosing the Cobute shutters for stairs?

Cobute precast stair installation

  • flexible system to fit diverse job requirements

  • Elements are easy and light to manoeuvre 

  • Easy and fast installation

  • Minimal shuttering, which guarantees a neat site management

  • Room for mistake is reduced as the principal reinforcement in the structural elements is fixed in the factory

  • When the Cobute elements are integrated, the project can be cast in only one pour, minimising risks of cold joints and cracks, with concrete savings.
