A cladding support device comprises a folded sheet metal body. The folded sheet method body includes a base wall, a top wall portion protruding out relative to the base wall, a side wall protruding from the base wall and having an upper edge adjacent the top wall portion; and a clamp on the top wall portion, the clamp including a substantially planar body with side edges extending between a coupled end to which the clamp is coupled to the sheet metal body and an outboard end and the clamp being positioned on the top wall with one side edge extending along the upper edge of the side wall.

A method is for installing a ceiling system attached to a structural ceiling surface. The method includes illuminating, in sequence and by a projector, different subsets of a set of optical sensors separately arranged in a known distribution pattern on the structural ceiling surface. Each optical sensor of the set of optical sensors is arranged to output a temporal signal indicative of a level of illumination. The method also includes determining an image plane relative to the projector based on the known distribution pattern of the set of optical sensors and the outputted temporal signals of each of the optical sensors, and displaying, by the projector, an image indicative of installation locations of the ceiling system at the image plane.

A system and device for leveling and aligning tiles and a method for leveling and aligning tiles are disclosed. In one embodiment of the tile leveling system, a tile leveling device includes an upright body having a head and base at opposite ends thereof. The base and the upright body are integral prior to a frangible separation. The tile leveling device is selectively threaded through a line-of-sight opening of a wedge device for use in an operational configuration.

A device for stabilizing a sheet material to a stud member includes two side members that sandwich the stud member and a back member joining the two side members together. One or more protrusions may extend inward from one or both of the side members so that the device is frictionally fit and secured to the stud member. A shelf extends away and outward from the back member so that the sheet material can be placed on the shelf before the sheet member is fastened to the stud member. The device can include an angled portion at the bottom of the back member so that a hammer can apply a force to the angled portion to cause the device to move away from the stud member for removal.

A method and assembly for laying and leveling adjacent tiles. The assembly includes a base member having a bottom plate and a cam tool. The cam tool is pivotally combined with the base member so that the cam tool rotates relative to the base member about an axis of rotation. The cam tool has a handle combined with a cam member. The cam member has a tile engaging surface around its outer periphery with a first portion that is a first distance from the axis of rotation and a second portion that is a second distance from the axis of rotation. Rotation of the cam tool around the axis of rotation causes the distance between the tile engaging surface and the bottom plate to change. One or more tiles is adapted to be placed between the tile engaging surface of the cam member and the bottom plate of the base member. The tiles are compressed between the tile engaging surface and the bottom plate as the cam tool is rotated to a desired position.

The present invention proposes a silent, safe, fast, multi-purpose and easy-to-service lifting mechanism. For this purpose, the mechanism comprises: a telescopic mast with a fixed segment (11) and a first telescopic segment (12) mounted so as to slide inside the fixed segment; a rack (13) having a set width and provided with teeth (131), which is attached to the first telescopic segment; a gear system comprising: a pinion (21) directly meshed with the rack, a driving shaft (22) which meshes with the pinion and is attached to a steering wheel, a reversible locking means for the driving shaft, designed to lock the driving shaft against rotation as long as no action is taken by a user.

A reliable swiveling fastening mechanism that allows a plate to be horizontally, obliquely and vertically fastened comprises, in the position of use: a vertical supporting profile to be arranged at the top of the mast, coaxially to the mast; two parallel backing plates mounted so as to swivel on the supporting profile and interconnected on one side by a plate carrier fastening component and on the other side by a U-shaped vertical position stop attached to the backing plates and arranged in such a way that the plate carrier fastening component is parallel to the supporting profile when the supporting profile is in contact with the vertical position stop; and a retractable stop supported by at least one backing plate so that the plate carrier fastening component forms an angle between 10° and 80° with the supporting profile when the supporting profile is in contact with the retractable stop.

A screw-driving machine support for a plate-lifting tool comprises a telescopic mast comprising a fixed segment and a first telescopic segment mounted so as to slide inside the fixed segment and a lifting mechanism using a gear or winch for the first sliding segment relative to the fixed segment. The lifting mechanism comprises a driving shaft with a rotation axis and a reversible fastening means with a shaft for screwing and unscrewing a screw-driving machine, which comprises, in the position of use a member for fastening to the mast, a lateral stop which is vertical, parallel and laterally offset to the axis of rotation of the driving shaft by a given center distance and is designed to lock a screw-driving machine handle laterally in the position of use and a member for adjusting the position of the vertical stop (420) relative to the axis of rotation of the driving shaft.
