The floor plate units consist of a single 65mm skin with a mesh of reinforcement
and a steel lattice girder cast-in. The mesh reinforcement provides the
required area of steel according to traditional limit state design. The
lattice girder acts as stabilizer for the temporary condition, i.e. lifting
and propping, and as a chair for the required top layer meshes. Before the
in-situ screed is added the units are supported by temporary props. Once
the screed is cast and cured the props can be removed.
Typical applications of Half Floor:
Floors to complement the Double Wall
System forming a complete monolithic shell.
Stand alone floors for any size project from a single house to an entire
warehouse floor slab.
Car parks, bridge decks.
Permanent shutter for locations with difficult access.
Cantilever slabs.
Advantages:
Typical width 2.5m, hence reduced amount of joints in ceiling to be
treated.
No precamber, direct application of décor can be achieved.
Holes in the slab are pre-engineered into the units ready for services.
Any services/conduits can be placed within the screed depth and cast-in
to eliminate false ceilings and save on building height.
Excellent acoustic characteristics.
Excellent fire resistance, Class 0, BS8110:Part 2
Bespoke units for any situation can be produced easily due to the CAD
process.
Design:
All of the design work required is based on the traditional limit state
design for ordinary reinforced concrete, (BS8110).
The slabs can be designed either as simply supported or continuous systems.
Our experienced design team will provide the most efficient solution for
you.
Complex geometry can be accommodated easily by the state of the art
CAD methods used in our design office.
Erection:
Temporary props are installed according to our shop drawing, our standard
details respectively, typically at 1500mm c/c prior to any unit being
placed.
The slab is to be hooked on to the crane and lifted into position onto
the props/beams place in step 1.
Services can now be installed, edges and recesses shuttered, if applicable
Top layer mesh is placed prior to pouring the in-situ concrete topping.
The slab surface can then be finished per Architects specification.
