Pliers for tightening parts for levelling cladding tiles, including: a first arm (1) with a handle (10) and a guide bar (11); a second arm (2) with a handle (20) and a contact surface (21) with a levelling wedge; a rotation shaft (4); and a supporting stop (3) comprising: a passage (31) for assembly in the guide bar; a shaft (32) assembled in a longitudinal slot (12) of the guide bar for the longitudinal movement of the supporting stop (3) with respect to the guide bar (11) and the relative rotation thereof between a fastening position with a pawl (13, 34) and a longitudinal movement position of the supporting stop (3) with respect to said guide bar (11); and a spring (33) which tends to maintain the supporting stop (3) in the fastening position with respect to the guide bar (11).

A flooring installation assembly for pressing a warped floorboard into position for installation includes a mounting plate that is mounted to a floor joist during installation of floorboards onto the floor joist. A pair of rods slidably extends through the mounting plate. Each of the rods extends through a pressure plate such that the pressure plate is spaced from the mounting plate. A push plate is coupled to each of the rods. A nut is coupled to the mounting plate, and a bolt is threaded into the nut to abut the pressure plate. The bolt urges the pressure plate away from the second section of the mounting plate when the bolt is rotated in a first direction such that the push plate compresses the floorboard into position for installation.

Provided are a fluid laying device, a floor tile laying robot, and a slurry laying method. The fluid laying device includes a chassis, a translation deviation correction mechanism, a slurry laying mechanism, and a slurry supply mechanism. The translation deviation correction mechanism is disposed on the chassis and includes a movable base configured to move in a direction perpendicular to a laying direction of fluid and a deviation correction detection member disposed on the movable base. The slurry laying mechanism is connected to the movable base. The slurry supply mechanism is disposed on the chassis to supply the fluid to the slurry laying mechanism. When the fluid laying device works, the deviation correction detection member controls the movable base according to received laser rays so that the slurry laying mechanism performs slurry laying linearly along the laying direction.

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.

Brick assemblies are prepared for covering the floor of an electrolysis cell. A tiling pattern is overlaid on a floor plan. Virtual tiles of the tiling pattern have a size and a shape of a template. Each brick assembly is formed to match zero or more departures from the template of a portion of the floor overlaid by each virtual tile. The brick assemblies are placed in piles and successively picked up for placement in adjacent positions on the floor of the electrolysis cell. Successive brick layers may be installed, in which tiling patterns are shifted to avoid overlap of the edges of bricks of the successive brick layers. A system comprises a working bench to prepare the brick assemblies, a vacuum brick lifter carried by a motorized structure to pick up and position the brick assemblies, and a controller to control the preparation and installation of the brick assemblies.

A spacing plate for tile lippage control has a base plate and at least one spacing member extending perpendicularly from an upper surface thereof. At least one spacing member comprises a pair of parallel elongate spacer walls defining parallel outer facing spacing control faces and the elongate spacer walls are spaced apart to define an elongate gap therebetween. As such, the spacing members may flexibly slightly to account for slight horizontal misalignments. Furthermore, edges of the baseplate may comprise cutouts dividing the baseplate into independently flexing leaves which can flexibly engage under individual tiles to account for slight vertical misalignments.
