## Abstract

A slab module includes a stone slab having a thickness of 3-10 mm. A reinforcing plate includes a first side fixed to a rear side of the stone slab. The reinforcing plate has an area corresponding to an area of the stone slab. A base is made of a rigid material and includes a coupling face on a top side thereof. The coupling face is fixed to a second side of the reinforcing plate. A plurality of posts is provided below the coupling face, with a compartment formed between the posts for receiving a wire.

## Claims

### Claim 1

A slab module for a raised floor comprising:
a stone slab having a thickness of 3-10 mm, with the stone slab having a rear side;
a reinforcing plate including a first side fixed to the rear side of the stone slab and a second side, with the reinforcing plate having an area corresponding to an area of the stone slab; and
a base made of a rigid material, with the base including a coupling face on a top side thereof, with the coupling face fixed to the second side of the reinforcing plate, with a plurality of posts provided below the coupling face, with a compartment formed between the plurality of posts and adapted to receive a wire,
with the first side of the reinforcing plate fixed to the stone slab by glue, with the coupling face of the base fixed to the second side of the reinforcing slab by glue, further comprising:
a bumper strip including first and second lateral edges and a flange extending between the first and second lateral edges, with the peripheral wall of base including a plurality of sides, with each of the plurality of sides of the peripheral wall including an engagement groove, with the first lateral edge of the bumper strip engaged in the engagement groove in one of the plurality of sides of the peripheral wall, with the second lateral edge of the bumper strip adapted to be engaged with an engagement groove in one of a plurality of sides of the peripheral wall of a similarly constructed slab module, with the flange located between the slab module and the similarly constructed slab module.

### Claim 2 (depends on 1)

The slab module as claimed in claim 1, with the first and second lateral edges of the bumper strip made of a rigid material, with the flange made of a soft material.
