A knob (1), for correctly laying tiles, comprises a first jaw (10) and a second jaw (20) which are connected to each other in such a way that said knob (1) can adopt a clamped configuration, in which the first and the second jaw (10,20) are in contact with each other, and a wide apart configuration, in which the first and the second jaw (10,20) are not in contact with each other.

A levelling spacer device for the application of slabs for covering surfaces, including a base having a lower surface and an opposite upper surface, a separator element extending upwardly from the upper surface of the base, a threaded stem which rises up from the separator element, a pressing element able to screw into the threaded stem, and a corner spacer that rises up from the upper surface of the base. The separator element includes a main zone having side faces parallel to one another and spaced apart defining a first thickness of the main zone. The corner spacer includes two side edges parallel to one another and square-angled with respect to the side faces. The separator element includes a central zone proximal to the base having a non-zero second thickness smaller than the first thickness. The corner spacer joins the central zone and has a longitudinal axis perpendicular to the side faces.

A device for leveling and aligning tiles and method for leveling and aligning tiles are disclosed. In one embodiment, the leveling device includes a body and two spaced and parallel strip members extending transversely from the body. Each of the spaced and parallel strip members extend to the front and rear of the body. Two opposing lateral open windows are formed in the body. A breakaway section is defined along the body. A wedge device is provided for penetrating one or more of the two opposing lateral open windows and exerting a force on the tiles for leveling them relative to each other.

The present application provides systems for installing tile on a flat surface, such as a wall, and methods of using same to install tile.

Disclosed are a ceramic tile leveling bracket, pushing and clamping pliers, and a ceramic tile leveling and laying system. The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket, an insertion block, and pushing and clamping pliers, wherein the ceramic tile leveling bracket is disposed at a junction of at least two adjacent ceramic tiles, one end of the insertion block is inserted into an insertion block receiving portion of the ceramic tile leveling bracket, and the pushing and clamping pliers push and clamp the insertion block into a ceramic tile leveling bracket such that a bottom face of the insertion block is tangent to upper surfaces of the ceramic tiles. The ceramic tile leveling and laying system is easy to operate, and improves the laying efficiency and laying quality.

A levelling spacer device (10) for laying slab-shaped products (P) comprising: at least one base (20) having a lower surface (21) and an opposite upper surface (22) defining a support plane for at least two tiles (P) placed side by side, which is placed at a first distance (d1) from the lower surface (21); a spacer bridge (30) provided with: two legs (31) placed side by side between each other along a flanking direction and each one rising from a portion of the upper surface (22) of the base (20), wherein each leg (31) is frangibly connected to the respective base portion by a predefined fracture line (310) placed at a second distance (d2) from the lower surface (21) greater than the first distance (d1), wherein the fracture line (310) is formed by a longitudinal cut that is parallel to the flanking direction; and crosspiece (32), which joins the top of the two legs (31); and a through opening (40) adapted to be crossed by a pressure wedge (50) along a crossing direction (C) orthogonal to the flanking direction, wherein the through opening (40) is peripherally delimited at the top by the crosspiece (32) of the bridge (30), laterally by the legs (31) of the bridge (30) and at the bottom by a central portion (220) of the upper surface (22) of the base (20) coplanar with the support plane.

Disclosed is a leveler to make coplanar the faces of two adjacent tiles (P) without using pincers or other tools. The leveler uses a disposable element and a wedge to be inserted in the disposable element, so as to push down the tiles and make them coplanar.

A levelling spacer device for the laying of slab-shaped products for coating surfaces, including at least one base having a lower surface and an opposite upper surface defining a support plane for two slab-shaped products placed side by side, a spacer bridge perimetrically delimiting a through opening adapted to be crossed by a pressure wedge along a crossing direction, wherein the bridge has at least two legs placed side by side between each other along a flanking direction orthogonal to the crossing direction and each one projecting from a respective portion of the upper surface of the base, in a direction orthogonal thereto, wherein each leg of the bridge is frangibly connected to the respective base portion, and a crosspiece, which joins the top of the two legs along the flanking direction, wherein each leg has an inner sidewall and an opposite outer sidewall converging on each other.
