If, in addition, the connection tab is not blocked by a screw on the head of the block, it can also rotate relative to the head of the block.

• Figure 9 shows the support element mounted via the connection tab on the head of the stud. Since the connection lug can rotate on the stud head 3, the support element 1 fixed on this connection lug can rotate 360 ° both in the direction and anticlockwise, as indicated by the arrows 50 and 51. As moreover the support element can slide on the connection lug this makes it possible to combine the rotational movement with a translational movement and thus apply the flaps against the wall or the wall. Finally the fact that the inserts can rotate and slide in the first and second window as well as in the hole will allow a wide range of adjustment to correctly place the inserts between the flooring elements and this for a wide range of geometry of these flooring elements.

• FIG. 10b illustrates the use of the support element according to the invention when the wall or the wall 25 form an angle. Thanks to the presence of the notch 7-1 it is possible to fold the first section of the flap 6-1 so that it matches the angle in the wall or the wall 25.

• the floor covering element will be supported by the support element and the stud.
• the covering element 26-1 To adjust the covering element 26-1 to the geometry of the wall or wall, it will suffice to cut an angle of this covering element so that it too matches the geometry of the wall or wall. Thanks to the fact that the support element can be moved over the head of the stud and therefore come into contact with the wall or the wall, the flooring element will be partly supported by the support element as far as the wall or the wall thus reducing the risk of it being cantilevered. The presence of the spacers in the first and second windows will allow the spacers to be placed correctly between the adjacent flooring elements.
• FIG. 10c illustrates the use of the support element according to the invention when the wall or the wall 25 form a 90 ° corner. It can be seen that the flap 6-1 has been removed to accommodate the support element with the corner geometry of the wall or of the wall. For this it was enough to break or cut in the flap 6-1 at the level of its foot 8-1. In case it would be necessary to still have a section of one of the flaps before reaching the corner of the wall or of the wall, it will suffice to remove only one section of the flap using the notch 7 as a cutting line.
