Installing a Lintel Supporting a Concrete Floor

STEP 1: Note: Please read "Installing a Cavity Lintel" in addition to the following.
concrete floor installation
  1. Check that the correct lintel is being used according to the manufacturer's lintel schedule design criteria.
  2. Bed the Lintel on full blocks and allow mortar to cure before applying floor loads.
  3. Raise both leaves of cavity wall together and allow masonary to cure sufficiently before applying heavy loads. Alternatively prop the lintel if large loads are to applied to fresh masonary.
  4. When using Catnic CH & CX Open back range with concrete floors, always ensure that the blockwork is built tight against the inner vertical face of the lintel, and that a mortar joint is added to the top of the blockwork so that the floor units have an even spread over inner flange of the lintel.


STEP 2:
cavity wall installation
  1. Avoid shock loading lintels during installation of concrete floor units and also any sideways loading while being lifted into position.
  2. Precast flooring units should be laid on a mortar bearing of the full inner leaf wall width and should not be dragged over supports.
  3. Avoid loading newly laid floors with building materials.
  4. Lintels must be built-in as illustrated, ensuring that the blockwork infill is well-jointed during construction and compatible with the strength of the masonary above.
