The present invention relates to a load transference element for laying concrete slabs intended to avoid differential settlements between adjacent concrete slabs in paving on elastic soils, which element has a base (1) and two anchorage elements (2), both of which are made of steel. It is essentially characterised in that it also includes a W- shaped joint blade (3) and a bar (4) for attaching the blade and supporting the formwork of the joint, making it possible to simultaneously create a retraction, contraction and dilation joint. The aforementioned element is attached to a connecting joint blade (6) and an intersection blade, which fit inside the blade (3) and both ensure the guiding and watertightness of the joints. This element, as well as efficiently ensuring the creation of a retraction joint, also guarantees watertightness by preventing water or other residual liquids present in the paving from infiltrating into the foundations and allowing perfect adaptation to the irregular oscillations of the foundations. It is intended to be used in road paving, industrial paving, paving in ports and airports and any paving with dynamic or static requirements.
