Abstract: Laminate flooring with coupling stem comprising long rectangular planks with two types of couplings, wherein the first is carried out by their longitudinal edges equally equipped with male/female hooks-type profiles configured for angular penetration, where the hook from a plank can penetrate into the corresponding hook of the other plank, the planks placed in a coplanar position, whereas the second coupling allows the joinery of the tops using a mechanical coupling comprising an engagement stem divided into two longitudinal halves, whose upper and lower faces equally have longitudinal microteeth, where the teeth on one side are slanted towards the center of the stem, such that each longitudinal half of said profile can be penetrating and self-locking in the grooves on the transversal edges the planks, thus finalizing the side by side engagement between the two planks.

Abstract: Floor panels are secured to a sub-floor by elongated elements, one of which is secured to the floor itself and has an inverted T-shape, the other of which elements defines downwardly open socket means for receiving an arrow shaped projection on the stem portion of that T-shaped support element. A precise fit is afforded between these elements 1 and 2 so that the floor panels are locked in place by engagement between the arrow shaped projection in the support element and the socket portion of the upper retaining element. An alternative version of the disclosure shows a more secure connection between these elements.
