Definitions

  • the present invention relates to the laying of concrete slabs and aims to remedy the various problems of stability, settlement and shrinkage experienced by the concrete slabs after their installation, these different problems always being found in the same places, namely at shrinkage joints and construction joints.
  • the construction joint covering the entire thickness of the slab - from 12 cm to 30 cm - is currently essential to allow the concrete to expand over the full span of the slab.
  • a construction joint is essential for any slab of a length equal to or greater than 60 m, it has the effect of allowing the total withdrawal of the concrete on the span without creating cracks.
  • the disadvantage of such a joint is that, the slab being made up of two independent parts from each other, separated by the joint with a width of more or less 1 cm, the vertical settlement is not not necessarily the same for both parties. This results in level differences, which can go up to 3 cm, and the lips of the seals then deteriorate in the passage of handling equipment and vehicles.
  • the removal joint squares the slab in portions of 25 m 2 to 40 m 2 ; it has a depth equal to 25% of the thickness of said slab. Its effect is to better control shrinkage while avoiding cracks as much as possible.
  • the invention also aims to improve the results already obtained in this field and relates to a method of producing a non-settling joint characterized in that it consists in placing on spacers a concrete bar provided in its part center of a loop directed downwards, to force said loop by a waiting bar welded horizontally on the concrete bar above the loop, to pour the slab and to saw the slab by cutting the bar wait, so that the loop takes position 0 and the concrete expands at the joint.
  • the loop is treated anti-rust and sheathed with insulation.
  • an anti-settlement joint firstly consists in placing spacers 1 at a determined distance, one of the other of the concrete bars 2 provided in their central part with a loop 3 directed downwards.
  • This concrete bar advantageously comes with a diameter of 8 mm and a total length of 90 cm.
  • this diameter and this length, as well as the importance of the loop 3, are to be determined according to the load or the thickness of the slab.
  • This loop 3 is treated anti-rust and is sheathed with insulation 4 to be determined also depending on the load or the thickness of the slab, it could be about 30 mm thick.
  • This loop is then forced, that is to say stretched inward, by means of a waiting bar 5 of 3 mm to 4 mm in diameter, welded horizontally above the loop 3, and the slab 6 is poured.
  • This welded waiting bar 5 is then cut at the time of sawing the slab, this sawing 7 allowing the loop 3 to take the zero position and causing the expansion of the concrete of the slab at the location of the joint.
  • a compression seal according to the invention has the advantage of being able to absorb loads or shocks thanks to the flexibility of the concrete bar 2 and the insulation 4 of the loop 3, which has the effect of avoiding cracks and differential settlements.
