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 sheetrock lifting device including a base with a protrusion centrally disposed on a front side of the base. A plurality of locking caster wheels is disposed on the base and on the protrusion. A pair of stanchions is used to house a battery and a manual wench. A pair of support rods supports the device by connecting the stanchions to the protrusion. A pair of stabilizing beams further supports the stanchions. A pulley device containing a pulley arm, pulley, and pulley cable is disposed on the stabilizing beams. An electric wench is disposed between the stabilizing beams and is in operational communication the battery. The electric wench raises and lowers a telescoping tube to which is attached a drywall frame. A manual wench alternately raises and lowers the telescoping tube with a cable hook connected to a ring on the telescoping tube.

An autonomous construction robotic system is disclosed which includes a processing unit, a robotic arm, the robotic arm is adapted to be coupled to a central attachment arm and thereby position the central attachment arm according to a plurality of degrees of freedom, a panel handling and fastening system, including a panel handling assembly coupled to the central attachment arm and adapted to pick and place a construction panel onto a framed structure within a construction zone, and a vision system adapted to provide visual information to the processing unit associated with the framed structure, wherein the processing unit processes the visual information to automatically determine placement position of the construction panel on the framed structure.

A system for applying a tile adhesive, including: an adhesive supplying device for supplying the tile adhesive on a surface of a tile, including a nozzle for emerging the tile adhesive and a pump unit for pumping the tile adhesive in the direction of the nozzle; and an automated supporting and moving device, in particular robot, for supporting and positioning the tile with respect to the nozzle so that the tile adhesive is distributable onto the surface of the tile when emerging from the nozzle.

A lifting cart for assist in building construction processes using precast wall panels can include a panel handling mechanism coupled to a movable vehicle. The panel handling mechanism can include a clamping mechanism, a rotational mechanism, a linear mechanism, and a tilting mechanism. The movable vehicle can include two sets of wheels configured to move the vehicle in perpendicular directions. The lifting cart can handle the precast wall panels, from a wall panel package delivered to the construction site to the final location of the wall panels between beams of the building frame.

The present drywall installation tool is configured to facilitate the installation of interior panels such as drywall, plywood or any applicable material on horizontal and vertical framed surfaces and to avoid the necessity of having more than one person to install each drywall panel and without using the floor as a supportive base for the installation tool.

The drywall sheet lifting device comprises a lower frame and an upper frame. The lower frame may comprise a set of wheels to allow the drywall sheet lifting device to be moved into position. The lower frame may comprise telescopic joints in the side supports and hinged joints in the front and rear support to permit reduction of size of the lower frame for storage and transportation purposes. The upper frame may be coupled to the lower frame via two uprights. The upper frame may comprise a plurality of center braces to support a sheet of drywall. The upper frame may comprise a plurality of stop plates to prevent the sheet of drywall from sliding off. The upper frame may pivot between a first position for loading and a second position for installing. The upper frame may be raised or lower via telescopic joints in the uprights.
