Definitions

• the present invention relates to the sector of levelling for tiles and more specifically consists of a levelling tie rod to be used also, but not only, in emergency conditions for the laying of slab elements for the cladding of surfaces comprising a universal base adaptable both to tie rods for wedge levelling spacer devices and to other types of levelling spacer devices, such as for example screw-type levelling spacer devices or more generally levelling spacer devices having a vertical septum or thin plate which rises from a base of said spacer.
• This system consists of an emergency system comprising a pin tie rod and a knob that tightens the tie rod by screwing.
• the pin tie rod of the Raimondi system has a base that, before screwing, must be rotated underneath the tiles so that the tie rod is locked underneath said tiles.
• the disadvantage of this system is that the tie rod requires a special knob that does not coincide with the knob used during the first levelling operation. Even more so, this knob does not coincide when the first levelling system is a wedge system. Therefore, this system is not a system that can be adapted to every situation. Furthermore, care must be taken to ensure that the base of the tie rod has completed the correct and complete rotation underneath the tile so that it is locked underneath it.
• tie rods disclosed in documents US2022341191A1 and US2016090746A1 cannot be used as emergency tie rods, i.e. as tie rods to be used after the first levelling operations have already been carried out. This is because they are made with materials, shapes and dimensions that do not make them compatible with the emergency use required.
• the tie rod of the US'191 document is made of metal and its disadvantage is that, with the same applied stress, it is a material that recovers its original shape with greater difficulty.
• the yield point of the metal is not compatible with the bending angles that are required for the tie rod that is the subject of this patent application to ensure that the base returns to a substantially orthogonal position with respect to the septum after it has been inserted under the tile. Therefore, the tie rod that is the subject of this application cannot be made of metal.
• the object of the present invention is to provide a base which is universal in shape and adaptable to a tie rod of any shape, whether for wedge-shaped levelling spacers or for other types of levelling spacers, such as screw-type levelling spacers or more generally levelling spacers having a vertical septum or thin plate which rises from a base of said spacer.
• a further object of the present invention is to provide a tie rod to be used in emergency situations but not only to recover and complete the work carried out up to the moment preceding the breakage of the tie rod used in a first levelling procedure.
• a further object of the present invention is to provide a tie rod that can be used in combination with the components of the initial levelling device without requiring the use of an additional pressing means to be clamped onto the tie rod, which would be separate and entirely different from the pressing means used for the initial levelling.
• a further object of the present invention is to provide a tie rod that can be inserted into a grout line between two adjacent tiles without the covering having to be removed first.
